Abstract
Epidemiological evidence presents that dust storms are related to respiratory diseases, such as pulmonary fibrosis (PF). However, the precise underlying mechanisms of SPM-elicited adverse effects still need to be investigated. Epithelial-mesenchymal transition (EMT) process is a characteristic of PF. We discussed whether suspended particulate matter (SPM) is involved in EMT induction via transforming growth factor-β1 (TGF-β1). In this study, a detailed elemental analysis (55 elements), particle size, and morphology were determined. To investigate the toxicity of SPM, an MTT test was performed to detect cell viability. Next, A549 cells were exposed to selected concentrations of SPM (20 and 40 µg/mL) for single and repeated exposures. The DCFH-DA assay showed that exposure to SPM could produce reactive oxygen species (ROS). The ELISA assay demonstrated increased levels of interleukin-8 (IL-8) and TGF-β1 in the supernatant. Western blot was used to detect the expression of proteins associated with EMT and the SMAD3-dependent pathway. Results of western blot demonstrated that E-cadherin was reduced, whereas p-SMAD3, vimentin, and α-smooth muscle actin were elevated. Our findings indicated that SPM triggered EMT by induction of oxidative stress, inflammation, and the TGF-β1/SMAD3 pathway activation.

Abstract
Despite advancements in elucidating biological mechanisms of cardiovascular remodeling, cardiovascular disease (CVD) remains the leading cause of death worldwide. When stratified by sex, clear differences in CVD prevalence and mortality between males and females emerge. Regional differences in phenotype and biological response of cardiovascular cells are important for localizing the initiation and progression of CVD. Thus, to better understand region and sex differences in CVD presentation, we have focused on characterizing in vitro behaviors of primary vascular smooth muscle cells (VSMCs) from the thoracic and abdominal aorta of male and female mice. VSMC contractility was assessed by traction force microscopy (TFM; single cell) and collagen gel contraction (collective) with and without stimulation by transforming growth factor-beta 1 (TGF-β1) and cell proliferation was assessed by a colorimetric metabolic assay (MTT). Gene expression and TFM analysis revealed region- and sex-dependent behaviors, whereas collagen gel contraction was consistent across sex and aortic region under baseline conditions. Thoracic VSMCs showed a sex-dependent sensitivity to TGF-β1-induced collagen gel contraction (female > male; p = 0.025) and a sex-dependent proliferative response (female > male; p < 0.001) that was not apparent in abdominal VSMCs. Although primary VSMCs exhibit intrinsic region and sex differences in biological responses that may be relevant for CVD presentation, several factors-such as inflammation and sex hormones-were not included in this study. Such factors should be included in future studies of in vitro mechanobiological responses relevant to CVD differences in males and females.

Abstract
This study is aimed to evaluate the effect and underling mechanism of dietary supplementation with pyrroloquinoline quinone (PQQ) disodium on improving inflammatory liver injury in piglets challenged with lipopolysaccharide (LPS). A total of seventy-two crossbred barrows were allotted into four groups as follows: the CTRL group (basal diet + saline injection); the PQQ group (3 mg/kg PQQ diet + saline injection); the CTRL + LPS group (basal diet + LPS injection) and the PQQ + LPS group (3 mg/kg PQQ diet + LPS injection). On days 7, 11 and 14, piglets were challenged with LPS or saline. Blood was sampled at 4 h after the last LPS injection (day 14), and then the piglets were slaughtered and liver tissue was harvested. The results showed that the hepatic morphology was improved in the PQQ + LPS group compared with the CTRL + LPS group. PQQ supplementation decreased the level of serum inflammatory factors, aspartate aminotransferase and alanine transaminase, and increased the HDL-cholesterol concentration in piglets challenged with LPS; piglets in the PQQ + LPS group had lower liver mRNA level of inflammatory factors and protein level of α-smooth muscle actin than in the CTRL + LPS group. Besides, mRNA expression of STAT3/TGF-β1 pathway and protein level of p-STAT3(Tyr 705) were decreased, and mRNA level of PPARα and protein expression of p-AMPK in liver were increased in the PQQ + LPS group compared with the CTRL + LPS group (P < 0·05). In conclusion, dietary supplementation with PQQ alleviated inflammatory liver injury might partly via inhibition of the STAT3/TGF-β1 pathway in piglets challenged with LPS.

Abstract
BACKGROUND The gut dysbiosis correlates with non-alcoholic steatohepatitis (NASH), involving the moderation of miRNAs. AIMS This study was aimed to investigate the correlation between gut microbiota and miR-582-3p in patients with non-alcoholic steatohepatitis (NASH) and to explore the possible regulation of miR-582-3p in the function of the activated hepatic stellate cells (HSCs). METHODS GSE69670 and GSE14435 datasets were analyzed by GEO2R. Plasma and fecal samples were obtained from the subjects, non-steatosis (n = 35), simple steatosis (n = 35), and NASH (n = 35). The variations in intestinal microbiota in the non-steatosis and NASH groups were analyzed using 16S rRNA sequencing. The expression of miR-582-3p among the groups was detected using RT-qPCR. Correlations between top-changed intestinal microbiota and miR-582-3p expression were analyzed using the Pearson correlation coefficient. Target gene identification was performed by prediction and dual-luciferase reporter assay. The effect of miR-582-3p on the cell function of TGF-β1-induced HSCs was assessed in vitro. RESULTS miR-582-3p was the common differentially expressed miRNA between GSE69670 and GSE14435. miR-582-3p was upregulated in NASH patients' plasma, as well as in TGF-β1-induced LX-2 cells. The non-steatosis and NASH groups showed significantly different intestinal microbiota distribution. miR-582-3p was positively correlated with specific microbiota populations. TMBIM1 was a target gene for miR-582-3p. Knockdown of miR-582-3p suppressed HSC proliferation and myofibroblast markers' expression but induced cell apoptosis, via TMBIM1. CONCLUSIONS This present study suggests that miR-582-3p promotes the progression of NASH. Knockdown of miR-582-3p may alleviate NASH by altering the gut microbiota composition and moderating TMBIM1.

Abstract
OBJECTIVE To determine whether celastrol, an inhibitor of the mechanosensitive transcriptional cofactor yes-associated protein-1 (YAP1), impairs the ability of TGFβ1 to stimulate fibrogenic activity in human gingival fibroblast cell line. DESIGN Human gingival fibroblasts were pre-treated with celastrol or DMSO followed by stimulation with or without TGFβ1 (4 ng/ml). We then utilized bulk RNA sequencing (RNAseq), real-time polymerase chain reaction (RT-PCR), Western blot, immunofluorescence, cell proliferation assays to determine if celastrol impaired TGFβ1-induced responses in a human gingival fibroblast cell line. RESULTS Celastrol impaired the ability of TGFβ1 to induce expression of the profibrotic marker and mediator CCN2. Bulk RNAseq analysis of gingival fibroblasts treated with TGFβ1, in the presence or absence of celastrol, revealed that celastrol impaired the ability of TGFβ1 to induce mRNA expression of genes within extracellular matrix, wound healing, focal adhesion and cytokine/Wnt signaling clusters. RT-PCR analysis of extracted RNAs confirmed that celastrol antagonized the ability of TGFβ1 to induce expression of genes anticipated to contribute to fibrotic responses. Celastrol also reduced gingival fibroblast proliferation, and YAP1 nuclear localization in response to TGFβ1. CONCLUSION YAP1 inhibitors such as celastrol could be used to impair pro-fibrotic responses to TGFβ1 in human gingival fibroblasts.

Abstract
Epigenetic modifications are involved in fibrotic diseases, such as idiopathic pulmonary fibrosis (IPF), and contribute to the silencing of anti-fibrotic genes. H3K27me3, a key repressive histone mark, is catalysed by the methyltransferase enhancer of Zeste homologue 2 (EZH2), which is regulated by the post-translational modification, O-linked N-Acetylglucosamine (O-GlcNAc). In this study, we explored the effects of O-GlcNAc and EZH2 on the expression of antifibrotic genes, cyclooxygenase-2 (Cox2) and Heme Oxygenase (Homx1). The expression of Cox2 and Hmox1 was examined in primary IPF or non-IPF lung fibroblasts with or without EZH2 inhibitor EZP6438, O-GlcNAc transferase (OGT) inhibitor (OSMI-1) or O-GlcNAcase (OGA) inhibitor (thiamet G). Non-IPF cells were also subjected to TGF-β1 with or without OGT inhibition. The reduced expression of Cox2 and Hmox1 in IPF lung fibroblasts is restored by OGT inhibition. In non-IPF fibroblasts, TGF-β1 treatment reduces Cox2 and Hmox1 expression, which was restored by OGT inhibition. ChIP assays demonstrated that the association of H3K27me3 is reduced at the Cox2 and Hmox1 promoter regions following OGT or EZH2 inhibition. EZH2 levels and stability were decreased by reducing O-GlcNAc. Our study provided a novel mechanism of O-GlcNAc modification in regulating anti-fibrotic genes in lung fibroblasts and in the pathogenesis of IPF.

Abstract
This study was aimed to investigate the preventive effects of N-acetyl-L-cysteine (NAC) against renal tubular cell injury induced by oxalate and stone formation and further explore the related mechanism. Transcriptome sequencing combined with bioinformatics analysis were performed to identify differentially expressed gene (DEG) and related pathways. HK-2 cells were pretreated with or without antioxidant NAC/with or silencing DEG before exposed to sodium oxalate. Then, the cell viability, oxidative biomarkers of superoxidase dismutase (SOD) and malondialdehyde (MDA), apoptosis and cell cycle were measured through CCK8, ELISA and flow cytometry assay, respectively. Male SD rats were separated into control group, hyperoxaluria (HOx) group, NAC intervention group, and TGF-β/SMAD pathway inhibitor group. After treatment, the structure changes and oxidative stress and CaOx crystals deposition were evaluated in renal tissues by H&E staining, immunohistochemical and Pizzolato method. The expression of TGF-β/SMAD pathway related proteins (TGF-β1, SMAD3 and SMAD7) were determined by Western blot in vivo and in vitro. CDKN2B is a DEG screened by transcriptome sequencing combined with bioinformatics analysis, and verified by qRT-PCR. Sodium oxalate induced declined HK-2 cell viability, in parallel with inhibited cellular oxidative stress and apoptosis. The changes induced by oxalate in HK-2 cells were significantly reversed by NAC treatment or the silencing of CDKN2B. The cell structure damage and CaOx crystals deposition were observed in kidney tissues of HOx group. Meanwhile, the expression levels of SOD and 8-OHdG were detected in kidney tissues of HOx group. The changes induced by oxalate in kidney tissues were significantly reversed by NAC treatment. Besides, expression of SMAD7 was significantly down-regulated, while TGF-β1 and SMAD3 were accumulated induced by oxalate in vitro and in vivo. The expression levels of TGF-β/SMAD pathway related proteins induced by oxalate were reversed by NAC. In conclusion, we found that NAC could play an anti-calculus role by mediating CDKN2B/TGF-β/SMAD axis.

Abstract
Articular cartilage injury is a common disease in clinical medicine. Because of its special physiological structure and lack of blood, lymph, and nerves, its ability to regenerate once damaged is very limited. In this study, we designed and synthesized a series of self- and coassembled cartilage-inducing functional peptide molecules and constructed a coassembled functional peptide hydrogel based on phenylboronic acid-o-dihydroxy "click chemistry" cross-linking to promote aggregation and signal transduction of mesenchymal stem cells (MSCs) in the early stage and differentiation toward cartilage, thereby promoting the repair of cartilage damage. Three functional peptide molecules were produced using solid-phase peptide synthesis technology, yielding a purity higher than 95%. DOPA-FEFEFEFEGHSNGLPL (DFP) and PBA-FKFKFKFKGHAVDI (BFP) were coassembled at near-neutral pH to form hydrogels (C Gels) based on phenylboronic acid-o-dihydroxy click chemistry cross-linking and effectively loaded transforming growth factor (TGF)-β1 with a release period of up to 2 weeks. Furthermore, chondrocytes and bone marrow mesenchymal stem cells (BMSCs) were cocultured with functional peptide hydrogels, and the results displayed that the coassembled functional peptide hydrogel group C Gels significantly promoted the proliferation of chondrocytes and MSCs. The chondrocyte markers collagen type I, collagen type II, and glycosaminoglycan (GAG) in the coassembled functional peptide hydrogel group were significantly higher than those in the control group, indicating that it can induce the differentiation of MSCs into cartilage. In vivo experiments demonstrated that the size and thickness of the new cartilage in the compound gel group were the most beneficial to cartilage regeneration. These results indicated that peptide hydrogels are a promising therapeutic option for cartilage regeneration.

Abstract
OBJECTIVES Our study aimed to clarify the role of mitogen-activated protein kinases (MAPKs) in transforming growth factor (TGF)-β1-stimulated mineralization in the human osteoblast-like MG63 cells. METHODS The viability of MG63 cells under TGF-β1 stimulation was assessed by MTS assay. Western blotting determined TGF-β1-mediated activation of extracellular signal-related protein kinase (ERK), p38, and c-Jun amino-terminal kinase (JNK). Mineralization-related gene expression was examined by quantitative real-time PCR, and mineral deposition levels were evaluated by alizarin red S staining. RESULTS TGF-β1 had no effect on MG63 cell proliferation. Activation of p38 was observed at 3 h post TGF-β1 stimulation. Moreover, JNK phosphorylation was upregulated by TGF-β1 from 1 to 6 h post stimulation, but had no activation on ERK phosphorylation throughout the experimental period. Treatment with JNK inhibitor diminished the alizarin red S-stained area in a dose-dependent manner. Mineral deposition was unaffected by MEK inhibitor, whereas p38 inhibitor increased the red-stained area. Gene expression levels of ALP and BSP were significantly decreased under treatment with JNK inhibitor and p38 inhibitor. The MEK inhibitor had no effect on the TGF-β1-mediated upregulation of ALP and BSP. Although all three inhibitors suppressed expression of COL I, none were found to stimulate expression of OCN. CONCLUSIONS Human osteoblast-like MG63 cells maturation and mineralization are induced through JNK activation of MAPK signaling in response to TGF-β1.

Transforming growth factor (TGF)-β1 plays a pivotal role in inducing osteogenic differentiation of mesenchymal stem cells (MSCs). In this study, we investigated the influence of connective tissue growth factor (CTGF), known to function synergistically with TGF-β1, on osteogenic differentiation in MSCs. METHODS UE7T-13 cells were treated with TGF-β1 and/or CTGF. Subsequently, protein levels of intracellular signaling pathway molecules were determined through western blot analysis. The mRNA expression levels of osteogenic differentiation markers were investigated using reverse transcription-quantitative polymerase chain reaction. Bone matrix mineralization was evaluated through alizarin red staining. RESULTS Co-treatment with TGF-β1 and CTGF resulted in the suppression of TGF-β1-induced phosphorylation of extracellular signal-regulated kinase 1/2, an intracellular signaling pathway molecule in MSCs, while significantly enhancing the phosphorylation of p38 mitogen-activated protein kinase (MAPK). In MSCs, co-treatment with CTGF and TGF-β1 led to increased expression levels of alkaline phosphatase and type I collagen, markers of osteogenic differentiation induced by TGF-β1. Osteopontin expression was observed only after TGF-β1 and CTGF co-treatment. Notably, bone sialoprotein and osteocalcin were significantly upregulated by treatment with CTGF alone. Furthermore, CTGF enhanced the TGF-β1-induced mineralization in MSCs, with complete suppression observed after treatment with a p38 MAPK inhibitor. CONCLUSIONS CTGF enhances TGF-β1-induced osteogenic differentiation and subsequent mineralization in MSCs by predominantly activating the p38 MAPK-dependent pathway.

Abstract
A combination of hydrogels and stem cell spheroids has been used to engineer three-dimensional (3D) osteochondral tissue, but precise zonal control directing cell fate within the hydrogel remains a challenge. In this study, we developed a composite spheroid-laden bilayer hydrogel to imitate osteochondral tissue by spatially controlled differentiation of human adipose-derived stem cells. Meticulous optimization of the spheroid-size and mechanical strength of gelatin methacryloyl (GelMA) hydrogel enables the cells to homogeneously sprout within the hydrogel. Moreover, fibers immobilizing transforming growth factor beta-1 (TGF-β1) or bone morphogenetic protein-2 (BMP-2) were incorporated within the spheroids, which induced chondrogenic or osteogenic differentiation of cells in general media, respectively. The spheroids-filled GelMA solution was crosslinked to create the bilayer hydrogel, which demonstrated a strong interfacial adhesion between the two layers. The cell sprouting enhanced the adhesion of each hydrogel, demonstrated by increase in tensile strength from 4.8 ± 0.4 to 6.9 ± 1.2 MPa after 14 days of culture. Importantly, the spatially confined delivery of BMP-2 within the spheroids increased mineral deposition and more than threefold enhanced osteogenic genes of cells in the bone layer while the cells induced by TGF-β1 signals were apparently differentiated into chondrocytes within the cartilage layer. The results suggest that our composite spheroid-laden hydrogel could be used for the biofabrication of osteochondral tissue, which can be applied to engineer other complex tissues by delivery of appropriate biomolecules.

Abstract
BACKGROUND Epithelial-to-mesenchymal transition (EMT) in nasal epithelial cells is involved in tissue remodeling of chronic rhinosinusitis with nasal polyps (CRSwNP). Our study investigated the molecular mechanisms that microRNA-182 (miR-182) regulated EMT in eosinophilic (Eos) and non-eosinophilic (non-Eos) CRSwNP. OBJECTIVE To investigate the mechanism by which miR-182 regulates EMT in human nasal epithelial cells (hNEPCs). METHODS The expression of EMT markers (E-cadherin, N-cadherin and vimentin), transforming growth factor (TGF)-β1, and miR-182 were determined by western blotting and reverse transcription-quantitative PCR (RT-qPCR). Fluorescence in situ hybridization (FISH) was used to detect the miR-182 localization. Additionally, EMT markers expression and cell morphology changes were checked upon treatment with TGF-β1, or TGF-β1 with miR-182 inhibitor, or miR-182 mimics, or miR-182 inhibitor alone in hNEPCs. RESULTS In both Eos CRSwNP and non-Eos CRSwNP, the expression levels of E-cadherin were downregulated while the expression levels of N-cadherin, vimentin, TGF-β1 and miR-182 were significantly upregulated compared with control nasal tissues. Additionally, more significant changes in these EMT markers were observed in the Eos-CRSwNP when compared with the non-Eos CRSwNP. Invitro hNEPCs model, TGF-β1 upregulated miR-182 expression and promoted EMT in hNEPCs, indicated by changes in cell morphology and EMT markers expression. Furthermore, these upregulations were reversed by miR-182 inhibitor. CONCLUSIONS This study showed that miR-182-induced EMT in response to TGF-β1 might promote nasal polypogenesis in both Eos CRSwNP and non-Eos CRSwNP, thus providing potential targets for the future development of novel therapeutic approaches for the management of CRSwNP.

Abstract
PURPOSE To investigate the role of Crocin on proliferation, fibrosis, and migration of orbital fibroblasts, as well as the possible signaling pathway. METHODS Immunofluorescence assay was performed to detect the expression of fibroblast marker proteins vimentin cytokeratin, desmin, and S-100. The quantity of 5‑ethynyl‑2'‑deoxyuridine-positive cells in orbital fibroblast was analyzed. Quantitative real-time PCR and western blots were performed to evaluate the expression level of fibrosis-related marker including alpha-smooth muscle actin, connective-tissue growth factor, collagen 1A1, and fibronectin. Scratch wound assays were performed to assess wound widths of orbital fibroblast. The expression and phosphorylation of extracellular signal-regulated kinase/signal transducer and activator of transcription 3 were evaluated using western blots. The phosphorylation of smad2 and smad3 was evaluated using immunofluorescence assay. RESULTS Crocin treatment reduced 5‑ethynyl‑2'‑deoxyuridine-positive cells, indicating inhibitory effect on orbital fibroblast proliferation. The expression levels of alpha-smooth muscle actin, connective-tissue growth factor, collagen 1A1 and fibronectin were declined in Crocin treatment. Delayed wound closures were observed in Crocin treatment. Furthermore, Crocin did not affect the expression of extracellular signal-regulated kinase and signal transducer and activator of transcription 3, but weakened extracellular signal-regulated kinase and signal transducer and activator of transcription 3 phosphorylation in orbital fibroblast. The phosphorylation of smad2 and smad3 was attenuated by Crocin as well. CONCLUSION In conclusion, Crocin inhibits the phosphorylation of extracellular signal-regulated kinase and signal transducer and activator of transcription 3, contributing to the inhibitory effect on proliferation, fibrosis, and migration of orbital fibroblast, suggesting that Crocin has potential to be a novel therapeutic candidate for thyroid-associated ophthalmopathy treatment.

Abstract
Mammary fibrosis in dairy cows is a chronic condition caused by mastitis, and can lead to serious culling of dairy cows resulting in huge economic losses in the dairy industry. MicroRNAs (miRNAs) exert an important role in regulating mammary gland health in dairy cows. This study investigated whether exosomal miRNAs in mammary epithelial cells can regulate the proliferation of bovine mammary fibroblasts (BMFBs) in mastitis. Liposome transfection technology was used to construct a cellular model of the overexpression and inhibition of miRNAs. The STarMir software, dual luciferase reporter gene test, real-time quantitative PCR (qRT-PCR), a Cell Counting Kit-8 (CCK-8), and a Western Blot and plate clone formation test were used to investigate the mechanism by which bta-miR-1296 regulates the proliferation of BMFBs. Target gene prediction results revealed that glutamate-ammonia ligase was a direct target gene by which bta-miR-1296 regulates cell proliferation. It was found that bta-miR-1296 significantly inhibited the proliferation of BMFBs. After BMFBs were transfected with a bta-miR-1296 mimic, mRNA expression in the extracellular matrix (ECM), α-smooth muscle actin (α-SMA), collagen type I alpha 1 chain (COL1α1) and collagen type III alpha 1 chain (COL3α1), and various cell growth factors (basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF), platelet-derived growth factor-BB (PDGF-BB), and transforming growth factor-β1 (TGF-β1)) were down-regulated, and the expressions of α-SMA, COL1α1, COL3α1, phospho-extracellular regulated protein kinases, phospho-protein kinase B, TGF-β1, and phospho-Smad family member3 proteins were inhibited. In conclusion, bta-miR-1296 can inhibit the proliferation of BMFBs and the synthesis of ECM in BMFBs, thus affecting the occurrence and development of mammary fibrosis in dairy cows and laying the foundation for further studies to clarify the regulatory mechanism of mammary fibrosis.

Abstract
Pulmonary fibrosis (PF) is a progressive and fatal lung disease with high incidence and a lack of effective treatment, which is a severe public health problem. PF has caused a huge socio-economic burden, and its pathogenesis has become a research hotspot. SIRT1 is a nicotinamide adenosine dinucleotide (NAD)-dependent sirtuin essential in tumours, Epithelial mesenchymal transition (EMT), and anti-aging. Numerous studies have demonstrated after extensive research that it is crucial in preventing the progression of pulmonary fibrosis. This article reviews the biological roles and mechanisms of SIRT1 in regulating the progression of pulmonary fibrosis in terms of EMT, oxidative stress, inflammation, aging, autophagy, and discusses the potential of SIRT1 as a therapeutic target for pulmonary fibrosis, and provides a new perspective on therapeutic drugs and prognosis prospects.

Abstract
BACKGROUND Hyperglycemia, which can lead to apoptosis, hypertrophy, fibrosis, and induces hyperinflammation in diabetic vascular complications due to oxidative stress. In order to elucidate the potential dual roles and regulatory signal transduction of TGF-β1 and TGF-β2 in human trabecular meshwork cells (HTMCs), we established an oxidative cell model in HTMCs using 5.5, 25, 50, and 100 mM d-glucose-supplemented media and characterized the TGF-β-related oxidative stress pathway. METHODS Further analysis was conducted to investigate oxidative damage and protein alterations in the HTMC caused by the signal transduction. This was done through a series of qualitative cell function studies, such as cell viability/apoptosis analysis, intracellular reactive oxygen species (ROS) detection, analysis of calcium release concentration, immunoblot analysis to detect the related protein expression alteration, and analysis of cell fibrosis to study the effect of different severities of hyperglycemia. Also, we illustrated the role of TGF-β1/2 in oxidative stress-induced injury by shRNA-mediated knockdown or stimulation with recombinant human TGF-β1 protein (rhTGF-β1). RESULTS Results from the protein expression analysis showed that p-JNK, p-p38, p-AKT, and related SMAD family members were upregulated in HTMCs under hyperglycemia. In the cell functional assays, HTMCs treated with rhTGFβ-1 (1 ng/mL) under hyperglycemic conditions showed higher proliferation rates and lower ROS and calcium levels. CONCLUSIONS To summarize, mechanistic analyses in HTMCs showed that hyperglycemia-induced oxidative stress activated TGF-β1 along with its associated pathway. GENERAL SIGNIFICANCE While at low concentrations, TGF-β1 protects cells from antioxidation, whereas at high concentrations, it accumulates in the extracellular matrix, causing further HTMC dysfunction.

Abstract
Arthrofibrosis, which causes joint motion restrictions, is a common complication following total knee arthroplasty (TKA). Key features associated with arthrofibrosis include myofibroblast activation, knee stiffness, and excessive scar tissue formation. We previously demonstrated that adiponectin levels are suppressed within the knee tissues of patients affected by arthrofibrosis and showed that AdipoRon, an adiponectin receptor agonist, exhibited anti-fibrotic properties in human mesenchymal stem cells. In this study, the therapeutic potential of AdipoRon was evaluated on TGFβ1-mediated myofibroblast differentiation of primary human knee fibroblasts and in a mouse model of knee stiffness. Picrosirius red staining revealed that AdipoRon reduced TGFβ1-induced collagen deposition in primary knee fibroblasts derived from patients undergoing primary TKA and revision TKA for arthrofibrosis. AdipoRon also reduced mRNA and protein levels of ACTA2, a key myofibroblast marker. RNA-seq analysis corroborated the anti-myofibrogenic effects of AdipoRon. In our knee stiffness mouse model, 6 weeks of knee immobilization, to induce a knee contracture, in conjunction with daily vehicle (DMSO) or AdipoRon (1, 5, and 25 mg/kg) via intraperitoneal injections were well tolerated based on animal behavior and weight measurements. Biomechanical testing demonstrated that passive extension angles (PEAs) of experimental knees were similar between vehicle and AdipoRon treatment groups in mice evaluated immediately following immobilization. Interestingly, relative to vehicle-treated mice, 5 mg/kg AdipoRon therapy improved the PEA of the experimental knees in mice that underwent 4 weeks of knee remobilization following the immobilization and therapy. Together, these studies revealed that AdipoRon may be an effective therapeutic modality for arthrofibrosis.

Abstract
Transforming growth factor (TGF)-β1 is a multifunctional cytokine that plays important roles in health and disease. Previous studies have revealed that TGFβ1 activation, signaling, and downstream cell responses including epithelial-mesenchymal transition (EMT) and apoptosis are regulated by the elasticity or stiffness of the extracellular matrix. However, tissues within the body are not purely elastic, rather they are viscoelastic. How matrix viscoelasticity impacts cell fate decisions downstream of TGFβ1 remains unknown. Here, we synthesized polyacrylamide hydrogels that mimic the viscoelastic properties of breast tumor tissue. We found that increasing matrix viscous dissipation reduces TGFβ1-induced cell spreading, F-actin stress fiber formation, and EMT-associated gene expression changes, and promotes TGFβ1-induced apoptosis in mammary epithelial cells. Furthermore, TGFβ1-induced expression of integrin linked kinase (ILK) and colocalization of ILK with vinculin at cell adhesions is attenuated in mammary epithelial cells cultured on viscoelastic substrata in comparison to cells cultured on nearly elastic substrata. Overexpression of ILK promotes TGFβ1-induced EMT and reduces apoptosis in cells cultured on viscoelastic substrata, suggesting that ILK plays an important role in regulating cell fate downstream of TGFβ1 in response to matrix viscoelasticity.

Airway fibrosis is among the pathological manifestations of benign central airway obstruction noted in the absence of effective treatments and requires new drug targets to be developed. Slit guidance ligand 2-roundabout guidance receptor 1 (Slit2-Robo1) is involved in fibrosis and organ development. However, its significance in airway fibrosis has not yet been reported. The study explored how the recombinant protein Slit2 functions in transforming growth factor-β1 (TGF-β1)-mediated airway fibrosis in vivo and in vitro. In this study, Slit2 expression initially increased in the tracheal granulation tissues of patients with tracheobronchial stenosis but decreased in the fibrotic tissue. In primary rat tracheal fibroblasts (RTFs), recombinant Slit2 inhibited the expression of extracellular matrices such as Timp1, α-SMA, and COL1A2, whereas recombinant TGF-β1 promoted the expression of Robo1, α-SMA, and COL1A2. Slit2 and TGF-β1 played a mutual inhibitory role in RTFs. Slit2 supplementation and Robo1 downregulation inhibited excessive extracellular matrix (ECM) deposition induced by TGF-β1 in RTFs via the TGF-β1/Smad3 pathway. Ultimately, exogenous Slit2 and Robo1 knockdown-mediated attenuation of airway fibrosis were validated in a trauma-induced rat airway obstruction model. These findings demonstrate that recombinant Slit2 alleviated pathologic tracheobronchial healing by attenuating excessive ECM deposition. Slit2-Robo1 is an attractive target for further exploring the mechanisms and treatment of benign central airway obstruction.

Abstract
PURPOSE To investigate collagen I, collagen V, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), lysyl oxidase (LOX), transforming growth factor β1 (TGF-β1) and interleukin-6 (IL-6) expression in healthy and keratoconus human corneal fibroblasts (HCFs and KC-HCFs), 24 h after Rose Bengal photodynamic therapy (RB-PDT). METHODS HCFs were isolated from healthy human corneal donors (n = 5) and KC-HCFs from elective penetrating keratoplasties (n = 5). Both cell cultures underwent RB-PDT (0.001% RB concentration, 0.17 J/cm2 fluence) and 24 h later collagen I, collagen V, NF-κB, LOX, TGF-β1 and IL-6 mRNA and protein expression have been determined using qPCR and Western blot, IL-6 concentration in the cell culture supernatant by ELISA. RESULTS TGF-β1 mRNA expression was significantly lower (p = 0.02) and IL-6 mRNA expression was significantly higher in RB-PDT treated HCFs (p = 0.01), than in HCF controls. COL1A1, COL5A1 and TGF-β1 mRNA expression was significantly lower (p = 0.04; p = 0.02 and p = 0.003) and IL-6 mRNA expression was significantly higher (p = 0.02) in treated KC-HCFs, than in KC-HCF controls. TGF-β1 protein expression in treated HCFs was significantly higher than in HCF controls (p = 0.04). IL-6 protein concentration in the HCF and KC-HCF culture supernatant after RB-PDT was significantly higher than in controls (p = 0.02; p = 0.01). No other analyzed mRNA and protein expression differed significantly between the RB-PDT treated and untreated groups. CONCLUSIONS Our study demonstrates that RB-PDT reduces collagen I, collagen V and TGF-β1 mRNA expression, while increasing IL-6 mRNA and protein expression in KC-HCFs. In HCFs, RB-PDT increases TGF-β1 and IL-6 protein level after 24 h.

Abstract
Within the tumor microenvironment (TME), cancer cells use mechanotransduction pathways to convert biophysical forces to biochemical signals. However, the underlying mechanisms and functional significance of these pathways remain largely unclear. The upregulation of mechanosensitive pathways from biophysical forces such as interstitial flow (IF), leads to the activation of various cytokines, including transforming growth factor-β (TGF-β). TGF-β promotes in part via a Smad-dependent signaling pathway the epithelial-mesenchymal transition (EMT) in cancer cells. The latter process is linked to increased cancer cell motility and invasion. Current research models have limited ability to investigate the combined effects of biophysical forces (such as IF) and cytokines (TGF-β) in a 3D microenvironment. We used a 3D-matrix based microfluidic platform to demonstrate the potentiating effect of IF on exogenous TGF-β induced upregulation of the Smad-signaling activity and the expression of mesenchymal marker vimentin in A549 lung cancer spheroids. To monitor this, we used stably integrated fluorescent based reporters into the A549 cancer cell genome. Our results demonstrate that IF enhances exogenous TGF-β induced Smad-signaling activity in lung cancer spheroids embedded in a matrix microenvironment. In addition, we observed an increased cell motility for A549 spheroids when exposed to IF and TGF-β. Our 3D-microfluidic model integrated with real-time imaging provides a powerful tool for investigating cancer cell signaling and motility associated with invasion characteristics in a physiologically relevant TME.

Abstract
Epithelial-mesenchymal transition (EMT) is the process by which epithelial cells acquire mesenchymal characteristics. This process induces cell migration and invasion, which are closely related to cancer metastasis and malignancy. EMT consists of various intermediate states that express both epithelial and mesenchymal traits, called partial EMT. Recently, several studies have focused on the roles of voltage-gated potassium (Kv) channels associated with EMT in cancer cell migration and invasion. In this study, we demonstrate the relationship between Kv3.4 and EMT and confirm the effects of cell migration and invasion. With TGF-β treatment, EMT was induced and Kv3.4 was also increased in A549 cells, human lung carcinoma cells. The knockdown of Kv3.4 blocked the EMT progression reducing cell migration and invasion. However, the Kv3.4 overexpressed cells acquired mesenchymal characteristics and increased cell migration and invasion. The overexpression of Kv3.4 also has a synergistic effect with TGF-β in promoting cell migration. Therefore, we conclude that Kv3.4 regulates cancer migration and invasion through TGF-β-induced EMT and these results provide insights into the understanding of cancer metastasis.

Abstract
BACKGROUND Ovarian cancer is the fifth leading cause of cancer-related death in women. Patients are usually diagnosed with advanced tumor metastass. Epithelial over cancer cells spread from primary tumor by undergoing epithelial mesenchymal transition (EMT). It has been suggested that alpha lipoic acid (ALA), a natural antioxidant lipophilic compound, reduces the oxidative stress by causing apoptosis and inhibition of proliferation of cell in cancer cells. The aim of our study was to establish a transforming growth factor β1 (TGF β1) dependent epithelial mesenchymal transition model in the SKOV-3 ovarian adenocarcinoma cell line which is an epithelial subtype of ovarian cancer and to investigate the effects of alpha lipoic acid on EMT and ovarian cancer migration. METHODS For establish an EMT model, SKOV-3 cells were treated with different dose of TGF β1 and XTT cell viability kit was used to find IC 50 dose of ALA. Four different groups that are control, TGF β1, ALA and ALA + TGF β1 were created. Changes in the expression of genes related to EMT markers that are E-cadherin, vimentin, Snail, Slug, Twist and Zeb were analyzed with quantitative real-time PCR. These proteins were determined with the immunocytochemistry method. The migration capacity was analyzed with wound healing assay. Matrigel invasion capacity test was used to show invasion and colonization test to show colonization. RESULTS The dose of TGF β1 was determined 100 ng/ml at 72 h, the IC50 dose of ALA 219.033 µM at 48 h was determined. EMT markers in the TGF β1 group were compatible with EMT and it was shown to inhibit EMT in the groups given ALA. According to wound healing, colonization and invasion experiments, proliferation and invasion increased in TGF β1 group, but decreased in ALA and combined groups (p < 0.05). CONCLUSION These results indicate that ALA suppresses the metastasis of ovarian cancer cells by regulating EMT, implying that ALA might be a potential therapeutic agent for the treatment of ovarian cancer.

Abstract
Ammonia can induce pulmonary fibrosis in humans and animals. Platycodin D (PLD) possesses various bioactive activities including anti-fibrotic properties. In this study, we aimed to explore the activity and mechanism of PLD in pulmonary fibrosis induced by ammonia. The mouse model of ammonia-induced lung fibrosis was established, and the role of PLD was assessed by H&E and Masson's trichrome staining. The differentially expressed genes (DEGs) were identified by RNA-seq and subjected to GO and KEGG pathway analyses. BEAS-2B cells were treated with NH4 Cl alone or along with PLD. Results showed that PLD attenuated ammonia-induced pulmonary inflammation and fibrosis in vivo. The extracellular matrix (ECM)-receptor interaction pathway was predicted as a prominent pathway underlying the anti-fibrotic function of PLD. In ammonia-induced mouse models and NH4 Cl-treated BEAS-2B cells, PLD could repress the activation of the TGF-β1 pathway. By incubating lung fibroblast HFL1 cells with the conditioned medium of BEAS-2B cells treated with NH4Cl alone or along with PLD, PLD was confirmed to attenuate NH4 Cl-induced ECM deposition in HFL1 cells. Our findings demonstrate that PLD exerts a protective function in ammonia-induced pulmonary fibrosis by repressing TGF-β1-mediated ECM remodeling, suggesting the potential therapeutic value of PLD in this disease.

Abstract
Renal fibrosis is a common pathway leading to progressive renal function loss in various forms of chronic kidney disease. Many fibrogenic factors regulate renal fibrosis; two key players are post-injury inflammation and transforming growth factor-β1 (TGF-β1)-induced myofibroblast differentiation. Myofibroblast differentiation is tightly regulated by the microtubule polymerization. Noscapine, an antitussive plant alkaloid, is a potent microtubule-interfering agent previously identified as a potential anticancer compound. Here, we examined how noscapine affects renal fibrogenesis in an in vitro renal fibroblast model and an in vivo unilateral ureteral obstruction (UUO) model. UUO mice were intraperitoneally treated with noscapine at 1 day before UUO surgery and daily thereafter. At 7 days post-surgery, kidneys were collected for further analysis. To analyze whether noscapine inhibits downstream TGF-β1-related signaling, we pre-incubated NRK-49F fibroblasts with noscapine and then performed TGF-β1 stimulation. In UUO mice, noscapine attenuated extracellular matrix protein deposition and the expression levels of type I collagen, type IV collagen, α-smooth muscle actin, and fibronectin. In addition, noscapine decreased tubulointerstitial inflammation in UUO kidneys by reducing TLR2 expression, modulating NLRP3 inflammasome activation, reducing macrophage infiltration, and antagonizing the M2 macrophage phenotype. Furthermore, noscapine pre-incubation suppressed the TGF-β1-induced fibroblast-myofibroblast transformation by downregulating the TGF-β/Smads signaling pathways in NRK-49F cells. These results suggest that noscapine reduces tubulointerstitial inflammation and fibrosis in the kidneys of UUO mice and inhibits the fibroblast-myofibroblast transformation induced by TGF-β1. Noscapine is an over-the-counter antitussive that has been used safely for several decades. Therefore, noscapine is an attractive therapeutic agent for inhibiting renal tubulointerstitial fibrosis.

Abstract
Calcitriol and transforming growth factor beta 1 (TGF-β1) are unrelated molecules that regulate biological processes according to the genetic target, cell type, and context. Several studies have shown independent effects of calcitriol and TGF-βs on the placenta, but there is no information regarding the impact of their combination on these cells. Therefore, this study analyzed the effects of calcitriol, TGF-β1, and their combination in primary cultures of human trophoblast cells using a whole genome expression microarray. Data analysis revealed a set of differentially expressed genes induced by each treatment. Enrichment pathway analysis identified modulatory effects of calcitriol on genes related to metabolic processes such as vitamin D, steroid, and fat-soluble vitamins as well as antimicrobial and immune responses. In relation to TGF-β1, the analysis showed a few differentially expressed genes that were mainly associated with the neutrophil immune response. Lastly, the analysis revealed that the combination of calcitriol and TGF-β1 up-regulated genes involving both immunologic processes and the biosynthesis of unsaturated fatty acids, eicosanoids, and lipoxins, among others. In contrast, pathways down-regulated by the combination were mostly associated with the catabolic process of acylglycerols and peptides, PPAR signaling pathway, cellular response to low-density lipoprotein stimulus, renin angiotensin system and digestion, mobilization and transport of lipids. Consistent with these results, the combined treatment on human trophoblast cells induced the accumulation of intracellular neutral lipid droplets and stimulated both gene and protein expression of 15-hydroxyprostaglandin dehydrogenase. In conclusion, the results revealed that differentially expressed genes induced by the combination modified the transcriptional landscape compared to each treatment alone, mainly altering the storage, activity and metabolism of lipids, which might have an impact on placental development.

Abstract
To investigate the potential protective effect of intermittent cold stimulation on lung tissues of broilers exposed to acute cold stress (ACS). A total of 384 one-day-old broilers were assigned to 4 experimental groups with 6 replicates of 16 birds each: control (CON) and ACS groups were reared at normal feeding temperature from d 1 to 42; cold treatment groups (CS3+ACS and CS9+ACS) were reared, respectively, at 3°C or 9°C for 5 h on alternate days below the CON group from d 15 to 35. Animals in CS3+ACS, CS9+ACS, and ACS groups were exposed at 10°C for 24 h on d 43. Subsequently, lung tissues were collected to perform histopathological examination and measurement of relevant indexes. The results showed that lung tissues in CS9+ACS and ACS groups exhibited increased inflammatory cell infiltrates and collagen deposition compared to the CON group, while this pathological phenomenon was less pronounced in the CS3+ACS group. Compared to CON group, H2O2 and MDA contents were increased, and the activities of antioxidant enzymes (CAT, SOD, GPx, T-AOC) were reduced in CS9+ACS and ACS group (P < 0.05); mRNA and protein levels of inhibitor of NF-κB, Smad7, matrix metallopeptidase (MMP)-2, MMP9, and antioxidant-related genes were downregulated, whereas mRNA and protein levels of genes related to NF-κB/NLRP3 pathway-regulated inflammation and TGF-β1/Smad pathway-regulated fibrosis were upregulated in cold-stressed broilers (P < 0.05). mRNA levels of heme oxygenase-1, NAD(P)H quinone oxidoreductase-1, and MMP9 were increased in CS3+ACS group (P < 0.05). Moreover, the expression of most antioxidant-related genes was increased, and that of inflammation- and fibrosis-related genes was reduced in CS3+ACS group (P < 0.05). Therefore, cold stress caused oxidative stress and inflammation, leading to pulmonary fibrosis in broilers, whereas intermittent mild cold stimulation at 3°C below normal rearing temperature alleviated fibrosis by inhibiting the TGF-β1/Smad pathway modulated by the Nrf2/HO-1 and NF-κB/NLRP3 signaling pathway. This study suggests that intermittent mild cold stimulation can be a potential strategy to reduce ACS-induced lung damage in broilers.

Abstract
Soluble E-cadherin (sE-cad) is an 80 kDa fragment derived from E-cadherin that is shed from the cell surface through proteolytic cleavage and is a biomarker in various cancers that promotes invasion and migration. Alveolar epithelial destruction, aberrant lung fibroblast migration and inflammation contribute to pulmonary fibrosis. Here, we hypothesized that E-cadherin plays an important role in lung fibrosis. In this study, we found that E-cadherin was markedly increased in the bronchoalveolar lavage fluid (BALF) and serum of mice with pulmonary fibrosis and that blocking sE-cad with HECD-1, a neutralizing antibody targeting the ectodomain of E-cadherin, effectively inhibited myofibroblast accumulation and collagen deposition in the lungs after bleomycin (BLM) exposure. Moreover, transforming growth factor-β (TGF-β1) induced the shedding of sE-cad from A549 cells, and treatment with HECD-1 inhibited epithelial-mesenchymal transition (EMT) stimulated by TGF-β1. Fc-E-cadherin (Fc-Ecad), which is an exogenous form of sE-cad, robustly promoted lung fibroblast migration. E-cadherin participates in bleomycin (BLM)-induced lung fibrosis by promoting EMT in the alveolar epithelium and fibroblast activation. E-cadherin may be a novel therapeutic target for lung fibrosis.

Abstract
OBJECTIVE Treatment options for acquired tracheal stenosis (ATS) are limited due to a series of pathophysiological changes including inflammation and cell proliferation. Micro ribonucleic acid-21-5p (miR-21-5p) may promote the excessive proliferation of fibroblasts. However, various types of fibrosis can be prevented with pirfenidone (PFD). Currently, the effect of PFD on miR-21-5p and its biological function has not been clarified. In this study, PFD was evaluated as a potential treatment for ATS by inducing fibroblast proliferation in lipopolysaccharide (LPS)-induced fibroblasts by targeting miR-21-5p. METHODS For 48 h, 1 g/ml LPS was used to generate fibroblasts in vitro, followed by the separation of cells into four groups: control, PFD, mimic, and mimic + PFD. The Cell Counting Kit-8 (CCK-8) technique was adopted to measure the proliferation of fibroblasts. Real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB) were used to measure the relative expressions of tumor necrosis factor-α (TNF-α), transforming growth factor-β1 (TGF-β1), drosophila mothers against decapentaplegic 7 (Smad7) and collagen type I alpha 1(COL1A1) messenger RNA (mRNA) and proteins, respectively. RESULTS (1) At 0, 24, 48, and 72 h, fibroblast growth was assessed using the CCK-8 method. Compared with the control group, the mimic group showed the highest fibroblast viability, and the PFD group showed the lowest fibroblast viability. However, fibroblast viability increased in the mimic + PFD group but decreased in the mimic one. (2) RT-qPCR and WB showed that the mimic group exhibited a significant up-regulation in the relative expressions of TNF-α, TGF-β1, and COL1A1 mRNA and proteins but a down-regulation in the relative expression of Smad7 mRNA and protein compared with the control one. In the PFD group, the results were the opposite. Nevertheless, the relative expressions of TNF-α, TGF-β1, and COL1A1 mRNA and proteins were increased, whereas that of Smad7 mRNA was decreased in the mimic + PFD group. The change was less in the mimic group. CONCLUSION PFD may have a preventive and curative effect on ATS by inhibiting fibroblast proliferation and the fibrotic process and possibly through down-regulating miR-21-5p and up-regulating Smad7 and its mediated fibrotic and inflammatory responses.

Abstract
Background Activated fibroblasts are reported partly of endothelial origin, derived through endothelial-mesenchymal transition (EndMT). Few studies have investigated EndMT in atrial fibrillation (AF), which may have a potential effect on cardiac fibrosis. Objective To investigate whether EndMT occurs in an animal model of AF. Methods A total of 80 Sprague‒Dawley rats (8 weeks, male, 200-250 g) were randomly divided into two groups: the control group and the AF group (n = 40 in each group). Rats in the AF group received a daily intravenous injection of acetylcholine-calcium chloride for seven days to establish an AF model, and rats in the control rats were injected with saline in the same way. At different time points (Day 3, Day 5, Day 7, Day 9, Day 11, Day 13, Day 15, and Day 17), we observed changes in EndMT-related indexes (CD31, VE-cadherin, FSP-1, TGF-β1 and collagen) and HIF-1α in the rat atria of two groups, as well as immunofluorescence co-expression of CD31/FSP-1 and VE-cadherin/FSP-1 in the endocardial endocardium of the atria. Results In the AF group, atrial EndMT was observed and enhanced with time. Compared with the control group, the levels of CD31 and VE-cadherin in the AF group decreased, while mesenchymal marker (FSP-1) and EndMT inducer (TGF-β1) were dynamically increased after Day 3. The co-expression of CD31/FSP-1 and VE-cadherin/FSP-1 was observed from Day 3 to the end of observation time Day 17 by immunofluorescence in AF rat hearts, indicating the existence of EndMT. In addition, the level of HIF-1α in the hearts of AF rats was increased. Conclusion As far as we know, this is the first study to explore the dynamic process of EndMT in an AF rat model. The presence of EndMT was verified in the atria of the AF rat model, and Day 7-Day 17 was the best observation time point for the model. This may lead to a better understanding of the pathological changes and mechanisms in AF with a short modeling cycle.

Abstract
To enhance the production of recombinant human transforming growth factor-beta1 (rhTGF-β1) in Chinese hamster ovary (CHO) cells, rhTGF-β1 was first characterized for endocytosis, signaling pathway, and overall maturation process. The mature rhTGF-β1 used for clinical application was internalized into CHO cells and inhibited the growth of CHO cells in a dose-dependent manner. However, mature rhTGF-β1 was mostly produced in the form of latent rhTGF-β1 in cultures of recombinant CHO (rCHO) cells producing rhTGF-β1 (CHO-rhTGF-β1). The concentration of active mature rhTGF-β1 in the culture supernatant of CHO-rhTGF-β1 cells was not high enough to compromise yield. In addition, a significant amount of unprocessed precursors was produced by CHO-rhTGF-β1 cells. Overexpression of PACEsol, a soluble form of furin, in CHO-rhTGF-β1 cells was effective for the proteolytic cleavage of unprocessed precursors. The highest mature rhTGF-β1 concentration (6.4 μg mL-1 ) was obtained with the PACEsol-expressing clone, which was approximately 45% higher than that of the parental clone (P < 0.01). Thus, a comprehensive understanding of the intrinsic properties of rhTGF-β1 with respect to the overall maturation process, signaling pathway, and endocytosis is essential for effectively enhancing the production of mature rhTGF-β1 in CHO cells.

Abstract
BACKGROUND/AIM Hypertrophic scars (HS) are an abnormal cutaneous condition of wound healing characterized by excessive fibrosis and disrupted collagen deposition. This study assessed the potential of a silicone patch embedded with chemically stable zirconium-based metal-organic frameworks (MOF)-808 structures to mitigate HS formation using a rabbit ear model. MATERIALS AND METHODS A silicone patch was strategically engineered by incorporating Zr-MOF-808, a composite structure comprising metal ions and organic ligands. Structural integrity of the Zr-MOF-808 silicone patch was validated using scanning electron microscopy and X-ray diffraction analysis. The animals were divided into three groups: a control, no treatment group (Group 1), a silicone patch treatment group (Group 2), and a group treated with a 0.2% loaded Zr-MOF-808 silicone patch (Group 3). HS suppression effects were quantified using scar elevation index (SEI), dorsal skin thickness measurements, and myofibroblast protein expression. RESULTS Histopathological examination of post-treatment HS samples revealed substantial reductions in SEI (34.6%) and epidermal thickness (49.5%) in Group 3. Scar hyperplasia was significantly diminished by 53.5% (p<0.05), while collagen density declined by 15.7% in Group 3 compared to Group 1. Western blot analysis of protein markers, including TGF-β1, collagen-1, and α-SMA, exhibited diminished levels by 8.8%, 12%, and 21.3%, respectively, in Group 3, and substantially higher levels by 21.9%, 27%, and 39.9%, respectively, in Group 2. On the 35th day post-wound generation, Zr-MOF-808-treated models exhibited smoother, less conspicuous, and flatter scars. CONCLUSION Zr-MOF-808-loaded silicone patch reduced HS formation in rabbit ear models by inducing the proliferation and remodeling of the wound healing process.

Abstract
Following wounding, endogenously secreted TGFβs drive resident and bone marrow-derived cells to convert into α-smooth actin (SMA)-rich, contractile myofibroblasts. The TGFβ effect is initiated by the phosphorylation of SMADs 2 and 3 (SMAD2/3). This event has been referred to as the canonical response to TGFβ. TGFβ also elicits other responses viewed as parallel events not directly connected to the SMAD activation, and thus referred to as noncanonical. A recognized response is the phosphorylation of the -activated kinase (TAK1/MAP3K), an upstream component of the mitogen-activated protein kinase (MAPK) cascade. We have now examined the relationship between these two effects of TGFβ1 at their earliest stages. The bulk of the studies were carried out with primary fibroblasts derived from the human cornea. The results' widespread relevance was confirmed in critical experiments with dermal-, and Tenon's capsule-derived fibroblasts. Cells were treated with kinase inhibitors or targeting siRNAs followed by induction by 2 ng/ml TGFβ1, and/or 10 ng/ml TNF-α. Cells were collected after 1 to 30 min for Western blot analysis and assayed for the accumulation of phosphorylated TAK1, ASK1, JNK1/2, p38, HPS27, MELK, SMAD2/3, and GAPDH. The effect of the kinase inhibitors on α-SMA expression and α-SMA stress fiber organization was also tested. For the immediate response to TGFβ1 we found that a) activation of the MAPK pathway was completed within 1 min after the addition of TGFβ1; b) phosphorylation of JNK1/2 was fully dependent on TAK1 and ASK1 activity, c) phosphorylation of MELK was fully dependent on JNK1/2 activity; d) phosphorylation of ASK1 depends on MELK activity, indicating the existence of an ASK1-MELK positive activation feedback loop; e) phosphorylation of SMAD2/3 started only after a 5 min period and reached a nadir after 10-15 min, f) the latter phosphorylation was fully blocked by inhibition of TAK1, ASK1, JNK1/2, and MELK, and siRNA-driven MELK downregulation; g) the inhibitors equally blocked the α-SMA protein expression, stress fiber development, and cell morphology changes at 72 h. These results demonstrate that the activation of the canonical pathway is fully subordinate to the activity of the MAPK pathway, challenging the concept of canonical and noncanonical TGFβ pathways and that SMAD2/3 activation is mediated by MELK, a kinase not previously associated with rapid pharmacological responses.

Abstract
OBJECTIVE At present, cartilage repair does not offer ideal efficacy. Fortunately, recent studies have claimed that RADA-16 peptide is an attractive therapeutic strategy for repairing cartilage defects. Therefore, this study tried to explore the effect of RADA-16 loaded with transforming growth factor-beta (TGF-β) 1 on cartilage differentiation of bone marrow mesenchymal stem cells (BMSCs). METHODS First, the RADA-16 peptide was synthesized by solid phase peptide, and a well-defined hydrogel was formed by supramolecular peptide self-assembly. Then, TGF-β1 (loading concentration of 10 ng/mL) was loaded into RADA-16, with scanning electron microscopy to observe the morphology of the TGF-β1/RADA-16 hydrogel and detect its related properties. Next, BMSCs were isolated from bone marrow samples and identified. TGF-β1/RADA-16 was co-cultured with L929, BMSCs, and C28/I2 cells, respectively, and the survival and proliferation ability of the cells was determined by live/dead cell staining and MTT assay. Chondrogenic differentiation and sGAG production of BMSCs were determined by Alcian blue staining and Blyscan assay, the expression of cartilage-associated genes by qRT-PCR, and the levels of inflammatory factors by ELISA. As for mechanism investigation, the Smad and ERK/MAPK signaling pathways were detected by western blot. RESULTS RADA-16 hydrogel exhibited a well-distributed and interconnected porous surface structure, with a loading rate of 91.9% for TGF-β1. The TGF-β1/RADA-16 hydrogel had good release and degradation properties, and had no negative effect on the survival and proliferation ability of BMSCs, L929, and C28/I2 cells. Importantly, TGF-β1/RADA-16 hydrogel significantly accelerated chondrogenic differentiation and sGAG generation in BMSCs, and decreased pro-inflammatory factor production. In addition, the hydrogel also significantly activated the Smad and ERK/MAPK pathways of BMSCs. CONCLUSION RADA-16 loaded with TGF-β1 has good biological properties and can enhance the chondrogenic differentiation ability of BMSCs.

Abstract
Dihydromyricetin (DHM) is a bioactive flavonoid extracted from Hovenia dulcis, which has various activities. In the present study, the molecular mechanism of dihydromyricetin (DHM) in relieving liver cirrhosis was investigated through network pharmacology and experimental verification. The cell model was induced by TGF-β1 activating the human hepatic stellate cell line (HSC; LX-2). The protein levels of α-SMA, collagen I, and collagen III and pathway-related proteins within LX-2 cells were detected using Western blot. EdU staining was conducted to detect cell proliferation. Immunofluorescence staining was performed to detect the expression levels of α-SMA and collagen I. Next, the drug targets of DHM were screened from the PubChem database. The differentially expressed genes in the liver cirrhosis dataset GSE14323 were identified. The expression of the identified drug targets in LX-2 cells was verified using qRT-PCR. The results showed that TGF-β1 treatment notably increased LX-2 cell viability, promoted cell proliferation, and elevated α-SMA, collagen I, and collagen III protein contents. DHM treatment could partially eliminate TGF-β1 effects, as evidenced by the inhibited cell viability and proliferation and reduced α-SMA, collagen I, and collagen III contents. After network pharmacology analysis, nine differentially expressed target genes (MMP2, PDGFRB, PARP1, BCL2L2, ABCB1, TYR, CYP2E1, SQSTM1, and IL6) in liver cirrhosis were identified. According to qRT-PCR verification, DHM could inhibit the expression of MMP2, PDGFRB, PARP1, CYP2E1, SQSTM1, and IL6, and enhance ABCB1 expression levels within LX-2 cells. Moreover, DHM inhibited mTOR and MAPK signaling pathways in TGF-β1-induced HSCs. In conclusion, DHM could inhibit HSC activation, which may be achieved via acting on MMP2, PDGFRB, PARP1, CYP2E1, SQSTM1, IL6, and ABCB1 genes and their downstream signaling pathways, including mTOR and MAPK signaling pathway.

Abstract
Hirsutella sinensis is the anamorph of Ophiocordyceps sinensis, and its mycelia has been used to effectively treat a variety of hepatobiliary diseases in clinical practice. In the present study, we performed a systematic study on the composition and structure of its polysaccharides, and then employed a TGF-β1-induced human intrahepatic bile duct epithelial cell-epithelial-mesenchymal transition (HIBEC-EMT) model to investigate their effects on treating primary biliary cholangitis (PBC) based on hepatic bile duct fibrosis. Four polysaccharide fractions were obtained from H. sinensis mycelia by hot-water extraction, DEAE-cellulose column and gradient ethanol precipitation separation. HSWP-1a was an α-(1,4)-D-glucan; HSWP-1b and HSWP-1d mainly consisted of mannoglucans with a backbone composed of 1,4-linked α-D-Glcp and 1,4,6-linked α-D-Manp residues branched at O-6 of the 1,4-linked α-D-Glcp with a 1-linked α-D-Glcp as a side chain; and HSWP-1c mainly contained galactomannoglucans. These polysaccharide fractions protected HIBECs from a TGF-β1-induced EMT, according to HIBEC morphological changes, cell viability, decreased E-cadherin and ZO-1 expression, and increased vimentin and collagen I expression. Furthermore, the effects of the polysaccharides might be mediated by inhibiting the activation of the TGF-β/Smad signaling pathway, which attenuated hepatic bile duct fibrosis and potential PBC effects.

Abstract
Chondrogenic induction of bone-marrow-derived stromal cells (BMSCs) is typically accomplished with medium supplemented with growth factors (GF) from the transforming growth factor-beta (TGF-β)/bone morphogenetic factor (BMP) superfamily. In a previous study, we demonstrated that brief (1-3 days) stimulation with TGF-β1 was sufficient to drive chondrogenesis and hypertrophy using small-diameter microtissues generated from 5000 BMSC each. This biology is obfuscated in typical large-diameter pellet cultures, which suffer radial heterogeneity. Here, we investigated if brief stimulation (2 days) of BMSC microtissues with BMP-2 (100 ng/mL) or growth/differentiation factor (GDF-5, 100 ng/mL) was also sufficient to induce chondrogenic differentiation, in a manner comparable to TGF-β1 (10 ng/mL). Like TGF-β1, BMP-2 and GDF-5 are reported to stimulate chondrogenic differentiation of BMSCs, but the effects of transient or brief use in culture have not been explored. Hypertrophy is an unwanted outcome in BMSC chondrogenic differentiation that renders engineered tissues unsuitable for use in clinical cartilage repair. Using three BMSC donors, we observed that all GFs facilitated chondrogenesis, although the efficiency and the necessary duration of stimulation differed. Microtissues treated with 2 days or 14 days of TGF-β1 were both superior at producing extracellular matrix and expression of chondrogenic gene markers compared to BMP-2 and GDF-5 with the same exposure times. Hypertrophic markers increased proportionally with chondrogenic differentiation, suggesting that these processes are intertwined for all three GFs. The rapid action, or "temporal potency", of these GFs to induce BMSC chondrogenesis was found to be as follows: TGF-β1 > BMP-2 > GDF-5. Whether briefly or continuously supplied in culture, TGF-β1 was the most potent GF for inducing chondrogenesis in BMSCs.

Abstract
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease (ILD) with unknown etiology, characterized by sustained damage repair of epithelial cells and abnormal activation of fibroblasts, the underlying mechanism of the disease remains elusive. METHODS To evaluate the role of Tuftelin1 (TUFT1) in IPF and elucidate its molecular mechanism. We investigated the level of TUFT1 in the IPF and bleomycin-induced mouse models and explored the influence of TUFT1 deficiency on pulmonary fibrosis. Additionally, we explored the effect of TUFT1 on the cytoskeleton and illustrated the relationship between stress fiber and pulmonary fibrosis. RESULTS Our results demonstrated a significant upregulation of TUFT1 in IPF and the bleomycin (BLM)-induced fibrosis model. Disruption of TUFT1 exerted inhibitory effects on pulmonary fibrosis in both in vivo and in vitro. TUFT1 facilitated the assembly of microfilaments in A549 and MRC-5 cells, with a pronounced association between TUFT1 and Neuronal Wiskott-Aldrich syndrome protein (N-WASP) observed during microfilament formation. TUFT1 can promote the phosphorylation of tyrosine residue 256 (Y256) of the N-WASP (pY256N-WASP). Furthermore, TUFT1 promoted transforming growth factor-β1 (TGF-β1) induced fibroblast activation by increasing nuclear translocation of pY256N-WASP in fibroblasts, while wiskostatin (Wis), an N-WASP inhibitor, suppressed these processes. CONCLUSIONS Our findings suggested that TUFT1 plays a critical role in pulmonary fibrosis via its influence on stress fiber, and blockade of TUFT1 effectively reduces pro-fibrotic phenotypes. Pharmacological targeting of the TUFT1-N-WASP axis may represent a promising therapeutic approach for pulmonary fibrosis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Dalbergia pinnata, as a natural and ethnic medicine in China, has been used for burns and wounds with a long history, which has the effect of invigorating blood and astringent sores. However, there were no reports on the advantage activity of burns. AIM OF STUDY The purpose of this study was to screen out the best active extract part of Dalbergia pinnata and investigate its therapeutic effect on wound healing and scar resolution. MATERIALS AND METHODS Rat burn model was established and the healing effects of extracts from Dalbergia pinnata on burn wounds were evaluated by the percentage of wound contraction and period of epithelialization. Histological observation, immunohistochemistry, immunofluorescence and ELISA were used for the examination of inflammatory factors, TGF-β1, neovascularization and collagen fibers through the period of epithelialization. In addition, the effect of the optimal extraction site on fibroblast cells was evaluated by cell proliferation and cell migration assays. The extracts of Dalbergia pinnata were analyzed by UPLC-Q/TOF-MS or GC-MS technique. RESULTS Compared to the model group, there were better wound healing, suppressed inflammatory factors, more neovascularization as well as newly formed collagen in the ethyl acetate extract (EAE) and petroleum ether extract (PEE) treatment groups. The ratio of Collagen I and Collagen III was lower in the EAE and PEE treatment groups, suggesting a potential for reduced scarring. Furthermore, EAE and PEE could repair wounds by up-regulating TGF-β1 in the early stage of wound repair and down-regulating TGF-β1 in the late stage. In vitro studies showed that both EAE and PEE were able to promote NIH/3T3 cells proliferation and migration compared with the control group. CONCLUSIONS In this study, EAE and PEE were found to significantly accelerate wound repair and might have an inhibitory effect on the generation of scars. It was also hypothesized that the mechanism might be related to the regulation of TGF-β1 secretion. This study provided an experimental basis for the development of topical drugs for the treatment of burns with Dalbergia pinnata.

Abstract
Cardiac fibrosis is characterized by pathological proliferation and activation of cardiac fibroblasts to myofibroblasts. Inhibition and reverse of transdifferentiation of cardiac fibroblasts to myofibroblasts is a potential strategy for cardiac fibrosis. Despite substantial progress, more effort is needed to discover effective drugs to improve and reverse cardiac fibrosis. The main reason for the slow development of antifibrotic drugs is that the traditional polystyrene culture platform does not recapitulate the microenvironment where cells reside in tissues. In this study, we propose an in vitro cardiac fibrotic model by seeding electrospun yarn scaffolds with cardiac fibroblasts. Our results show that yarn scaffolds allow three-dimensional growth of cardiac fibroblasts, promote extracellular matrix (ECM) deposition, and induce the transdifferentiation of cardiac fibroblasts to myofibroblasts. Exogenous transforming growth factor-β1 further promotes cardiac fibroblast activation and ECM deposition, which makes it a suitable fibrotic model to predict the antifibrotic potential of drugs. By using this platform, we demonstrate that both Honokiol (HKL) and Pirfenidone (PFD) show potential in antifibrosis to some extent. HKL is more efficient in antifibrosis than PFD as revealed by biochemical composition, gene, and molecular analyses as well as histological and biomechanical analysis. The electrospun yarn scaffold provides a novel platform for constructing in vitro fibrotic models to study cardiac fibrosis and to predict the antifibrotic efficacy of novel drugs.

Abstract
Paraquat (PQ) is a highly effective and highly toxic herbicide that is highly toxic to both humans and animals. Pulmonary fibrosis is the primary cause of fatality in patients with PQ poisoning, there is no effective drug treatment yet. 2-Methoxyestradiol (2ME) is a natural metabolite of estradiol with anti-tumor, anti-angiogenesis, and anti-proliferative effects. Whether 2ME has the potential to inhibit pulmonary fibrosis induced by PQ is unclear. This study aims to investigate the potential effects and mechanism of 2ME on PQ-induced pulmonary fibrosis. C57BL/6 mice and A549 cells were exposed to PQ to establish pulmonary fibrosis model. In vivo, Hematoxylin and eosin (H&E) staining was utilized to assess the pathological characteristics. Masson's trichrome staining was employed to evaluate the collagen deposition. Western blot and immunohistochemistry were conducted to determine the expressions of fibrosis markers. In vitro, the expressions of epithelial-mesenchymal transition (EMT) markers were detected using western blot and immunofluorescence to evaluated the potential inhibition of PQ-induced EMT by 2ME. And proteins associated with the TGF-β1/Smad2/3 signaling pathway were measured by western blot in vivo and in vitro. The result found that 2ME can ameliorated PQ-induced pulmonary fibrosis and inhibit the activation of TGF-β1/Smad2/3 signaling pathway. These findings suggest that 2ME may serve as a potential therapeutic agent for treating PQ-induced pulmonary fibrosis.

Abstract
BACKGROUND Although aberrant expression of CDGSH iron sulfur domain 2 (CISD2) contributes to the tumorigenesis and progression of numerous human cancers, the biological function of CISD2 and its specific prognostic value in lung squamous cell carcinoma (LUSC) have yet to be comprehensively explored. The current study aimed to elucidate the role of CISD2 in LUSC as well as the underlying molecular mechanisms. METHODS Immunohistochemistry was conducted to detect the protein expression of CISD2 and analyze whether high expression of CISD2 affects the overall survival (OS) of LUSC patients. Cell proliferation, colony formation, wound healing and Transwell invasion assays were performed to clarify whether CISD2 contributes to LUSC cell proliferation and disease progression. Quantitative real-time reverse transcription-PCR and western blot assays were used to detect the levels of transcription factors and key epithelial-mesenchymal transition (EMT)-related markers in LUSC cells after CISD2 knockdown and overexpression to determine whether CISD2 regulates transforming growth factor-beta (TGF-β)-induced EMT in LUSC. RESULTS Immunohistochemistry of human tissue microarrays containing 90 pairs of adjacent and cancerous tissues revealed that CISD2 is considerably overexpressed in LUSC and strongly linked to poor OS. Functional experiments suggested that silencing endogenous CISD2 inhibited the growth, colony formation, migration, and invasion of H2170 and H226 cell lines. Exogenous overexpression of CISD2 facilitated these phenotypes in SK-MES-1 and H2170 cells. Furthermore, CISD2 promoted EMT progression by increasing the expression of mesenchymal markers (N-cadherin, vimentin, Snail, and Slug) as well as SMAD2/3 and reducing the expression of the epithelial marker E-cadherin. Mechanistically, our studies provide the first evidence that CISD2 can promote EMT by enhancing TGF-β1-induced Smad2/3 expression in LUSC cells. CONCLUSION In conclusion, our research illustrates that CISD2 is highly expressed in LUSC and may facilitate LUSC proliferation and metastasis. Thus, CISD2 may serve as an independent prognostic marker and possible treatment target for LUSC.

Abstract
Background: Hyperglycemia usually impairs wound healing by dysregulating the inflammatory response and angiogenesis. This study aimed to examine the synergistic effect of dapagliflozin and Zamzam water (ZW) on the healing of diabetic wounds and to explore their anti-inflammatory and proangiogenic effects.Materials and methods: A full-thickness excisional wound was made on the backs of all groups after two weeks of diabetes induction. Forty rats were divided into five groups, with eight rats per group; Group 1: Control non-diabetic rats; Group II: Untreated diabetic rats; Group III: Diabetic rats drinking ZW; Group IV: Diabetic rats receiving an oral dose of 1 mg/kg dapagliflozin; and Group V: Received both dapagliflozin and ZW. The healing of diabetic wounds was assessed by measuring wound closure, oxidative stress markers, immunohistochemical staining of NF-βB, VEGF, CD34, CD45, Ki-67, and eNOS, gene expression of MMP-9, TGF-β1, EGF-b1, FGF, and Col1A1, protein levels of TNFα, IL-1β, IL6, Ang II, and HIF-1α by ELISA assay, and histological examination with H & E and Masson's trichrome. Combined treatment with dapagliflozin and ZW significantly (p < 0.05) enhanced the wound closure and antioxidant enzyme level, with apparent histological improvement, and shortened the inflammatory stage of the diabetic wound by decreasing the level of inflammatory markers NF-κB, TNF-α, IL-1β, IL6, and CD45. Therefore, it improved angiogenesis markers VEGF, CD34, eNOS, EGF-β1, FGF, Ang II, and HIF-1α, increasing Ki-67 cellular proliferation. Moreover, it enhanced the remodeling stage by increasing MMP-2, TGF-β1, and Col1A1 levels compared to diabetic rats.

Abstract
Although many efforts have been made to improve management strategies and diagnostic methods in the past several decades, the prevention of anastomotic complications, such as anastomotic leaks and strictures, remain a major clinical challenge. Therefore, new molecular pathways need to be identified that regulate anastomotic healing, and to design new treatments for patients after anastomosis to reduce the occurrence of complications. Rabbits were treated with a MST1/2 inhibitor XMU-XP-1, a Chinese medicine formula Shenhuang plaster (SHP) or a control vehicle immediately after surgery. The anastomotic burst pressure, collagen deposition, and hydroxyproline concentration were evaluated at 3 and 7 days after the surgery, and qRT-PCR and western-blot analyses were used to characterize mRNA and protein expression levels. Both XMU-XP-1 and SHP significantly increased anastomotic burst pressure, collagen deposition, and the concentration of hydroxyproline in intestinal anastomotic tissue at postoperative day 7 (POD 7). Importantly, SHP could induce TGF-β1 expression, which activated its downstream target Smad-2 to activate the TGF-β1 signaling pathway. Moreover, SHP reduced the phosphorylation level of YAP and increased its active form, and treatment with verteporfin, a YAP-TEAD complex inhibitor, significantly suppressed the effects induced by SHP during anastomotic tissue healing. This study demonstrated that activation of the Hippo-YAP pathway enhances anastomotic healing, and that SHP enhances both the TGF-β1/Smad and YAP signaling pathways to promote rabbit anastomotic healing after surgery. These results suggest that SHP could be used to treat patients who underwent anastomosis to prevent the occurrence of anastomotic complications.

Abstract
Vocal fold scar formation due to vocal fold injury (VFI) is a common cause of surgery or trauma-induced voice disorders. Severe scar formation can lead to reduced voice quality or even be life-threatening. Here, we investigated the role of autophagy in VFI, focusing on fibrosis as a consequence of autophagy in inducing VFI. A VFI model was constructed in rats by dissecting the lamina propria tissue from the thyroarytenoid muscle. Real-time PCR and Western blot were used to analyze expressions of autophagy markers, including Beclin1 and Atg7, in VFI. Tgfb1 and Col1a1 were assessed to determine the correlation of fibrosis with VFI progression and autophagy levels. Rat vocal fold fibroblasts were also treated with TGF-β1 or rapamycin, which activates and suppresses autophagy respectively, to explore how autophagy regulates fibrosis in VFI. Initially, we observed that autophagy was downregulated in vocal fold mucosa after VFI in rats. This was particularly evident by the time-dependent downregulation of Beclin1 and Atg7 following VFI. Concurrently, levels of Tgfb1 and Col1a1 also surged, hinting at elevated fibrosis levels. Furthermore, our experiments with TGF-β1 stimulation revealed that it inhibited autophagy in rat vocal fold fibroblasts. Interestingly, when we introduced rapamycin, this effect was reversed. Our data suggest that autophagy is a suppressor of VFI by alleviating fibrosis, making targeting autophagy a potential therapeutic route in VFI.NEW & NOTEWORTHY The study has demonstrated that autophagy is a suppressor of VFI by alleviating fibrosis, making autophagy a potential therapeutic target in VFI.

Abstract
OBJECTIVE To observe whether metformin (MET) inhibits transforming growth factor-β1 (TGF-β1)/Smad3 signaling pathway by activating adenosine activated protein kinase (AMPK), so as to alleviate the pulmonary fibrosis caused by paraquat (PQ) poisoning in mice. METHODS Male C57BL/6J mice were randomly divided into the Control group, PQ poisoning model group (PQ group), MET intervention group (PQ+MET group), AMPK agonist group (PQ+AICAR group), and AMPK inhibitor group (PQ+MET+CC group), according to a random number table method. A mouse model of PQ poisoning was established by one-time peritoneal injection of 1 mL PQ solution (20 mg/kg). The Control group was injected with the same volume of normal saline. After 2 hours of modeling, the PQ+MET group was given 2 mL of 200 mg/kg MET solution by gavage, the PQ+AICAR group was given 2 mL of 200 mg/kg AICAR solution by intraperitoneal injection, the PQ+MET+CC group was given 2 mL of 200 mg/kg MET solution by gavage and then 1 mL complex C (CC) solution (20 mg/kg) was intraperitoneally injected, the Control group and PQ group were given 2 mL of normal saline by gavage. The intervention was given once a day for 21 consecutive days. The 21-day survival rate of ten mice in each group was calculated, and the lung tissues of remaining mice were collected at 21 days after modeling. The pathological changes of lung tissues were observed under light microscope after hematoxylin-eosin (HE) staining and Masson staining, and the degree of pulmonary fibrosis was evaluated by Ashcroft score. The content of hydroxyproline in lung tissue and oxidative stress indicators such as malondialdehyde (MDA) and superoxide dismutase (SOD) were detected. The protein expressions of E-cadherin, α-smooth muscle actin (α-SMA), phosphorylated AMPK (p-AMPK), TGF-β1 and phosphorylated Smad3 (p-Smad3) in lung tissue were detected by Western blotting. RESULTS Compared with the Control group, the 21 days survival rate was significantly reduced, lung fibrosis and Ashcroft score were significantly increased in PQ group. In addition, the content of hydroxyproline, MDA and the protein expressions of α-SMA, TGF-β1 and p-Smad3 in lung tissue were significantly increased, while the activity of SOD and the protein expressions of E-cadherin and p-AMPK were significantly decreased in PQ group. Compared with the PQ group, the 21 days survival rates of mice were significantly improved in the PQ+MET group and PQ+AICAR group (70%, 60% vs. 20%, both P < 0.05). The degree of pulmonary fibrosis and the Ashcroft score were significantly reduced (1.50±0.55, 2.00±0.63 vs. 6.67±0.52, both P < 0.05). The content of hydroxyproline and MDA in lung tissue, as well as α-SMA, TGF-β1 and p-Smad3 protein expressions were significantly reduced [hydroxyproline (mg/L): 2.03±0.11, 3.00±0.85 vs. 4.92±0.65, MDA (kU/g): 2.06±1.48, 2.10±1.80 vs. 4.06±1.33, α-SMA/GAPDH: 0.23±0.06, 0.16±0.06 vs. 1.00±0.09, TGF-β1/GAPDH: 0.28±0.03, 0.53±0.05 vs. 0.92±0.06 p-Smad3/GAPDH: 0.52±0.04, 0.69±0.06 vs. 1.11±0.10, all P < 0.05], SOD activity and the protein expressions of E-cadherin and p-AMPK were significantly increased [SOD (μmol/g): 39.76±1.35, 33.03±1.28 vs. 20.08±1.79, E-cadherin/GAPDH: 0.91±0.08, 0.72±0.08 vs. 0.26±0.04, p-AMPK/GAPDH: 0.62±0.04, 0.60±0.01 vs. 0.20±0.04, all P < 0.05]. However, these protective effects of MET were inhibited by the addition of AMPK inhibitor CC solution. CONCLUSIONS MET can effectively alleviate the degree of pulmonary fibrosis in mice poisoned with PQ, and its mechanism may be related to the activation of AMPK and inhibition of TGF-β1/Smad3 signaling pathway, which can be inhibited by AMPK inhibitor CC.

Abstract
OBJECTIVE Human umbilical cord perivascular cells (HUCPVCs) are derived from the human umbilical cord perivascular tissue and are expected to replace mesenchymal stromal cells in the future. We investigated the synergistic effects of fibroblast growth factor 2 (FGF-2) and transforming growth factor-beta 1 (TGF-β1) on HUCPVC mineralization. DESIGN We prepared HUCPVCs with (FGF(+)HUCPVCs) or without FGF-2 (FGF(-)HUCPVCs) in the presence of activated vitamin D3, a bone morphogenic protein inhibitor, and TGF-β1. We examined the cell proliferative capacity, expression of various hard tissue-forming cell gene markers, and mineralization induction ability and identified the crystalline phases of the mineralized nodules. RESULTS FGF(+)HUCPVCs exhibited higher intracellular alkaline phosphatase (ALP) gene expression and ALP activity, and their cell proliferation rate was higher than that of FGF(-)HUCPVCs. The expression levels of osteoblast marker genes increased in FGF(+)HUCPVCs, whereas those of elastic fiber and muscle cell markers increased in FGF(-)HUCPVCs. The expression of genes related to matrix vesicle-mediated mineralization was increased in FGF(+)HUCPVCs. While FGF(-)HUCPVCs displayed myofibroblast-like properties and could not induce mineralization, FGF(+)HUCPVCs demonstrated the ability to produce mineralized nodules. The resulting mineralized nodules consisted of hydroxyapatite as the major phase and minor amounts of octacalcium phosphate. The mineralized nodules exhibited the morphological characteristics of bone hydroxyapatite, composed of fibrous hydroxyapatite nanorods and polycrystalline sheets. CONCLUSION We found that FGF-2 synergizes with TGF-β1 and is a key factor in the differentiation of HUCPVCs into osteoblast-like cells. Thus, HUCPVCs can potentially serve as a new stem cell source for future bone regeneration and dental treatments.

Abstract
Perioperative neurocognitive disorder (PND) is a common complication of surgery and anesthesia, especially among older patients. Microglial activation plays a crucial role in the occurrence and development of PND and transforming growth factor beta 1 (TGF-β1) can regulate microglial homeostasis. In the present study, abdominal surgery was performed on 12-14 months-old C57BL/6 mice to establish a PND model. The expression of TGF-β1, TGF-β receptor 1, TGF-β receptor 2, and phosphor-smad2/smad3 (psmad2/smad3) was assessed after anesthesia and surgery. Additionally, we examined changes in microglial activation, morphology, and polarization, as well as neuroinflammation and dendritic spine density in the hippocampus. Behavioral tests, including the Morris water maze and open field tests, were used to examine cognitive function, exploratory locomotion, and emotions. We observed decreased TGF-β1 expression after surgery and anesthesia. Intranasally administered exogenous TGF-β1 increased psmad2/smad3 colocalization with microglia positive for ionized calcium-binding adaptor molecule 1. TGF-β1 treatment attenuated microglial activation, reduced microglial phagocytosis, and reduced surgery- and anesthesia-induced changes in microglial morphology. Compared with the surgery group, TGF-β1 treatment decreased M1 microglial polarization and increased M2 microglial polarization. Additionally, surgery- and anesthesia-induced increase in interleukin 1 beta and tumor necrosis factor-alpha levels was ameliorated by TGF-β1 treatment at postoperative day 3. TGF-β1 also ameliorated cognitive function after surgery and anesthesia as well as rescue dendritic spine loss. In conclusion, surgery and anesthesia induced decrease in TGF-β1 levels in older mice, which may contribute to PND development; however, TGF-β1 ameliorated microglial activation and cognitive dysfunction in PND mice.

Abstract
Bone marrow mesenchymal stem cell (BSMC)-derived extracellular vehicles (EVs) have a pivotal therapeutic potential in hepatic fibrosis (HF). Activation of hepatic stellate cells (HSCs) is the key mechanism in HF progression. Downregulation of miR-192-5p was previously observed in activated HSCs. Nonetheless, the functions of BSMC-derived exosomal miR-192-5p in activated HSCs remain unclear. In this study, transforming growth factor (TGF)-β1 was used to activate HSC-T6 cells to mimic HF in vitro. Characterization of BMSCs and BMSC-derived EVs was performed. Cell-counting kit-8 assay, flow cytometry, and western blotting revealed that TGF-β1 increased cell viability, promoted cell cycle progression, and induced upregulation of fibrosis markers in HSC-T6 cells. Overexpression of miR-192-5p or BMSC-derived exosomal miR-192-5p suppressed TGF-β1-triggered HSC-T6 cell activation. RT-qPCR revealed that protein phosphatase 2 regulatory subunit B'' alpha (PPP2R3A) was downregulated in miR-192-5p-overexpressed HSC-T6 cells. Luciferase reporter assay was used for verifying the relation between miR-192-5p and PPP2R3A, which showed that miR-192-5p targeted PPP2R3A in activated HSC-T6 cells. Collectively, BMSC-derived exosomal miR-192-5p targets PPP2R3A and inhibits activation of HSC-T6 cells.

Abstract
BACKGROUND Breast cancer-related depression (BCRD) is strongly associated with BC and increases recurrence and mortality. This study investigated the role of kaempferol in the pathogenesis of BCRD and its underlying mechanism. METHODS 4T1 mouse BC cells were treated with corticosterone (Cort) in vitro to develop a neuronal injury model, and a BCRD mouse model was established by injecting 4T1 cells and Cort. The effects of kaempferol on 4T1 cells and BCRD models were measured by behavioral tests, Cell Counting Kit-8 assay, wound healing assay, colony formation assay, Western blot analysis, quantitative real-time PCR, hematoxylin and eosin staining, enzyme-linked immunosorbent assay, and immunofluorescence. BCRD cells were transfected with the cyclo-oxygenase-2 (COX-2) overexpression plasmid to study the role of the COX-2/prostaglandin E2 (PGE2) axis in the anti-BCRD activity of kaempferol. The connection between kaempferol and COX-2 was analyzed by molecular docking. RESULTS Kaempferol reduced the viability, migration, and clones of 4T1 cells and inhibited BC growth and depression-like behavior in mice. Kaempferol alleviated inflammation in BCRD, decreased interleukin 1 beta (IL-1β) and IL-6 levels, and increased transforming growth factor beta 1 (TGF-β1) and IL-10 levels. In addition, kaempferol elevated the levels of serotonin, dopamine, and norepinephrine and the amount of 5-Bromo-2'-deoxyuridine/neuronal nuclei-positive cells. Kaempferol downregulated COX-2 and PGE2, and kaempferol could dock with the protein structure of COX-2. Overexpression of COX-2 reduced BCRD viability, upregulated IL-1β and IL-6 levels, and downregulated TGF-β1 and IL-10 expression. Overexpression of COX-2 reversed the protective effects of kaempferol. CONCLUSION Kaempferol exerted anti-BCRD effects, at least in part by inhibiting the COX-2/PGE2 pathway, which regulates neuroinflammation, neurotransmitter imbalance, and defective neurogenesis. Therefore, kaempferol may be a promising candidate active ingredient for treating BCRD.
