Kavishahi NN, Rezaee A, Jalalian S. The Impact of miRNAs on the Efficacy of Tamoxifen in Breast Cancer Treatment: A Systematic Review. Clin Breast Cancer 2024:S1526-8209(24)00026-0. [PMID: 38413339 DOI: 10.1016/j.clbc.2024.01.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 01/17/2024] [Accepted: 01/22/2024] [Indexed: 02/29/2024]
Abstract
Seventy percent of breast cancer patients have an active estrogen receptor. Tamoxifen interferes with estrogen's ability to bind to cancer cells. The most challenging aspect of tamoxifen, however, is that breast cancer cells become resistant to its effects. Some studies have shown that alterations in miRNA expression contribute significantly to drug resistance in breast cancer. Therefore, the present systematic review aims to investigate miRNAs that significantly influence the response to tamoxifen treatment. The present study follows the PRISMA instructions. The Web of Science, PubMed, and Scopus databases were searched to retrieve English articles. The searches were conducted up to September 11, 2022. The search strategy included the terms "Tamoxifen", "Breast Neoplasm", and "MicroRNA". The inclusion criteria of this study are English, original, and experimental studies investigating miRNAs that are effective in the treatment efficacy of tamoxifen. A total of 565 articles were retrieved. After screening, 75 studies met our inclusion criteria. This systematic review study examined 105 miRNAs, of which 44 have a positive effect, and 47 miRNAs inhibit tamoxifen function. Fourteen miRNAs have a controversial effect, ie, some studies show positive and negative effects. The study of miRNAs affecting tamoxifen function in breast cancer patients may facilitate the identification of individuals at higher risk of disease recurrence. Conversely, it can potentially utilize appropriate interventions to defeat drug resistance effectively.

Abstract
Long noncoding RNAs (lncRNAs) are important regulators of bone metabolism. In this study, lncRNA microarray analysis was used to identify differentially expressed lncRNAs in differentiated osteoclasts. lncRNA-Gm5532 is highly expressed during osteoclast differentiation. lncRNA-Gm5532 knockdown impairs osteoclast formation and bone resorption. Mechanistic experiments show that lncRNA-Gm5532 functions as a competing endogenous RNA (ceRNA) and acts as a sponge for miR-125a-3p, which promotes TNF receptor-associated factor 6 (TRAF6) expression. miR-125a-3p mimics suppress osteoclast differentiation and TAK1/NF-κB/MAPK signaling. The miR-125a-3p inhibitor reverses the negative effects of siGm5532 on osteoclast differentiation. In summary, our study reveals that lncRNA-Gm5532 functions as an activator in osteoclast differentiation by targeting the miR-125a-3p/TRAF6 axis, making it a novel biomarker and potential therapeutic target for osteoporosis.

FASEB J 2023; 37:e23146. [PMID: 37584664 DOI: 10.1096/fj.202300851r] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 06/28/2023] [Accepted: 08/03/2023] [Indexed: 08/17/2023]
Abstract
Adipogenesis is tightly regulated by various factors, including genes and microRNAs. Excessive fat deposition is the key feature of obesity, which is a low-grade chronic inflammatory disease. Follistatin-like 1 (FSTL1) has been reported to be an important mediator involved in various inflammatory diseases. However, the underlying mechanism of FSTL1 in preadipocyte differentiation and inflammatory response is still unclear. The current study was designed to explore the biological function and potential mechanism of FSTL1 in mouse subcutaneous preadipocyte differentiation. We found that FSTL1 was highly expressed in the early stage of differentiation and subsequently decreased sharply, suggesting that FSTL1 played a possible role in adipogenesis. Meanwhile, the gain- and loss-of-function assays showed that FSTL1 was not only involved in the inflammatory response by inducing the expression of pro-inflammatory factors IL-1β and CCL2 but also significantly attenuated preadipocyte differentiation, as evidenced by the reduction of lipid accumulation and the levels of adipogenic genes, including PPARγ and FABP4. In addition, the target gene prediction and luciferase reporter assay validated that miR-125a-3p targeted the 3' UTR region of FSTL1. These results demonstrated that miR-125a-3p negatively regulated the expression of FSTL1 at the mRNA and protein levels. Furthermore, overexpressing miR-125a-3p in preadipocytes dramatically accelerated adipogenic differentiation and downregulated the levels of IL-1β and CCL2, which were in accordance with the knockdown of FSTL1. On the contrary, treatment with miR-125a-3p inhibitors attenuated adipogenesis but induced the expression of inflammatory genes. In summary, this study suggests a positive function of FSTL1 in adipocyte-induced inflammation and negatively regulates preadipocyte differentiation. Further studies demonstrated that miR-125a-3p could reverse the effect by targeting FSTL1, which might provide a better understanding of treating obesity-related inflammatory diseases.

Abstract
Introduction miR-125a-3p could have a role in gastric cancer by targeting HER2. This study aimed to investigate the expression pattern of miR-125a-3p, identify the expression level of its target gene in gastric carcinoma, and test its effect in HER-2 positive gastric carcinoma cells. Materials and Methods The levels of miR-125a-3p in both cancer and noncancer tissues were measured by using Quantitative real-time polymerase chain in 70 gastric carcinomas. Immunohistochemical study was used to measure the expression of HER2 protein in these carcinomas. In addition, the level of expression of this miRNA is correlated to different pathological and clinical parameters. The effects of miR-125a-3p alone and in combination with 5-FU (fluorouracil) on the growth of HER2 positive (NUGC4) and HER2 negative (ECC10) gastric carcinoma cells were also analyzed by in vitro studies. Results Most gastric cancer tissues samples showed downregulation of miR-125a-3p (84%) when compared to their noncancer tissues. Significant correlations of downregulation of miR-125a-3p with cancer recurrence and pathological staging of gastric carcinoma (P = 0. 02 and 0.02, respectively) were noted. HER2 protein expression correlated significantly and inversely with miR-125a-3p expression (P < 0.05). A reduction in cell growth rate was noted significantly in miR-125a-3p transfected gastric carcinoma cells when 5-FU was added to them in comparison to other control cells (P < 0.01). When both gastric carcinoma cell lines were transfected with miR-125a-3p, a significantly higher growth inhibition percentage in HER2 positive (NUGC4) cell line was seen in comparison to the HER2 negative (ECC10) cells (P < 0.01). Conclusion miR-125a-3p plays a significant role in the pathogenesis of gastric carcinoma. Therapeutic transfection of miR-125a-3p in HER2 positive gastric cancer cells resulted in reduced cell proliferation and potentiate the effect of 5-FU.

Abstract
Breast cancer (BC) leads to the most amounts of deaths among women. Chemo-, endocrine-, and targeted therapies are the mainstay drug treatments for BC in the clinic. However, drug resistance is a major obstacle for BC patients, and it leads to poor prognosis. Accumulating evidences suggested that noncoding RNAs (ncRNAs) are intricately linked to a wide range of pathological processes, including drug resistance. Till date, the correlation between drug resistance and ncRNAs is not completely understood in BC. Herein, we comprehensively summarized a dysregulated ncRNAs landscape that promotes or inhibits drug resistance in chemo-, endocrine-, and targeted BC therapies. Our review will pave way for the effective management of drug resistance by targeting oncogenic ncRNAs, which, in turn will promote drug sensitivity of BC in the future.

Abstract
BACKGROUND MiRNAs can affect the radiosensitization of head and neck squamous cell carcinoma (HNSCC). We aimed to analyze the function of miR-125 family members in HNSCC using The Cancer Genome Atlas (TCGA) and determine their effect on radiation in laryngeal squamous cell cancer (LSCC). METHODS First, we systematically analyzed the role of the miR-125 family in HNSCC using the TCGA database and found that miR-125a-5p is associated with radiotherapy. We then performed comprehensive enrichment analysis of miR-125a-5p and predicted target genes. Then, we performed transfection, cell proliferation assays, reverse transcription polymerase chain reaction, apoptosis assays, micronucleus tests, and western blotting on hep-2 cells selected with puromycin. RESULTS MiR-125 family members exhibited significantly different expression in HNSCC. They were significantly associated with tumor-node-metastasis staging, clinical stages, and histological grades. Radiation therapy had a statistically effect on miR-125 family members, except miR-125a-3p. Moreover, miR-125a-5p was related to overall survival in LSCC. Thus, we predicted 110 target genes and seven hub genes of miR-125a-5p. The proliferation rate of cells transfected with lentivirus vector expressing miR-125a-5p was significantly reduced compared to the other groups. The radiation effect was enhanced in cells transfected with miR-125a-5p. The ratio of apoptotic cells transfected and exposed to X-rays (10 Gy) was distinctly higher than that of the Ad-control group. Western blotting analysis revealed that miR-125a-5p upregulated the apoptotic regulators P53 and rH2AX. Thus, miR-125a-5p may increase radiosensitivity in LSCC via upregulation of pro-apoptotic genes. CONCLUSIONS MiR-125 family members could be prognostic biomarkers of HNSCC and improve HNSCC sensitivity to radiotherapy by activating P53. Upregulating miR-125a-5p via lentivirus vectors may be a novel strategy to strengthen the effect of radiotherapy on LSCC.

Abstract
The etiology of systemic lupus erythematous (SLE) remains unclear. Pyroptosis, a new model of programmed cell death, was poorly explored in the pathogenesis of SLE. We found cell pyroptosis in CD4+T cells of SLE patients and kidneys from MRL/lpr mice by examining caspase-1 and gasdermin D (GSDMD) in by RT-PCR, Western blot, and levels of IL-1β, IL-18 and TNF-α were detected by RT-PCR and Elisa. Expression of caspase-1 and GSDMD and levels of IL-1β, IL-18, TNF-α decreased significantly after downregulation of hsa_circ_0012919 (p < 0.05). Inhibition of miR-125a-3p enhanced expression of caspase-1 and GSDMD (p < 0.05), and increased the release of IL-1β, IL-18 and TNF-α (p < 0.05), thereby counteracting the effect of hsa_circ_0012919 knockdown on pyroptosis. Finally, we identified GSDMD as the target gene of miR-125a-3p. Silencing GSDMD reversed the effect of 5-aza-deoxycytidine in increasing release of IL-1β, IL-18, TNF-α and activating caspase-1, but it could be reversed by miR-125a-3p inhibitor. In conclusion, hsa_circ_0012919 regulated the pyroptosis in the CD4+ T cells of SLE patients by miR-125a-3p/GSDMD axis.

Abstract
OBJECTIVE T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignancy, and T-ALL patients are prone to early disease relapse and suffer from poor outcomes. The crucial function of RNA-binding proteins (RBPs) has been reported in the progression of cancers by regulating the expression of transcripts. This study aimed to reveal the role and molecular regulatory mechanism of RBP Pumilio2 (PUM2) in T-ALL. METHODS The expression of genes was detected by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blot analysis. The viability, proliferation, and apoptosis of T-ALL cells were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, 5-ethynyl-2'-deoxyuridine, and flow cytometry analysis. Luciferase reporter, RNA pulldown, and RNA immunoprecipitation assays were performed to confirm the binding of PUM2 to RBM5. The combination between RNA-binding motif protein 5 (RBM5) and microRNA (miR)-28-5p was validated using luciferase reporter assay. RESULTS Our data revealed that PUM2 was highly expressed in T-ALL blood samples and cell lines. PUM2 knockdown suppressed the proliferation but accelerated the apoptosis of T-ALL cells in vitro. Additionally, RBM5 exhibited a low expression level in T-ALL samples and cells. PUM2 negatively regulated RBM5 via targeting its 3'untranslated region (3'UTR). Moreover, PUM2 competitively bound to RBM5 3'UTR with miR-28-5p. Rescue experiments showed that RBM5 knockdown reversed the anti-tumor effects mediated by PUM2 knockdown in T-ALL cells. CONCLUSION PUM2 plays as a novel oncogenic RBP in T-ALL by competitively binding to RBM5 mRNA with miR-28-5p.

Abstract
Background Cyclin-dependent kinases (CDKs) are cell cycle regulators, and abnormal activation can accelerate tumor cell proliferation. However, The relation between CDKs dysregulation to colorectal cancer incidence and progression have not been examined in detail. Methods:Differences in CDKs expression between colorectal cancer and normal tissues, associations between expression and clinical prognosis, incidence and frequencies of CDKs gene mutations, and the influences of CDKs on tumor infiltration by immune cells were examined by analyses of Oncomine, Gene Expression Profiling Interactive Analysis, Kaplan-Meier plotter, cBioPortal, GeneMANIA, and TIMER databases. Results Colorectal cancer tissues showed enhanced expression levels of CDKs 1/2/4/5/6/8/12/13/19 but reduced CDK3 expression. CDK7 was highly expressed in some colorectal cancer tissues but downregulated in others. Expression levels of CDK1/3/4/7/8/10/11b/13/18/19/20 were correlated with clinical stage, and CDK 5/10/12/16 expression levels predicted prognosis and survival. Differential CDKs expression correlated with cell cycle progression, amino acid polypeptide modifications, and activation of other protein kinases. Expression levels of all CDKs except CDK16 were correlated with infiltration of CD4+T, CD8+T, B and Tregs cells. Conclusions CDK 1 and 4 could be used as diagnostic biomarkers for CRC. CDK 5/10/12/16 can be utilized as prognostic biomarkers.

Effects of Yogurt Intake on Cardiovascular Strain during Outdoor Interval Walking Training by Older People in Midsummer: A Randomized Controlled Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19084715. [PMID: 35457579 PMCID: PMC9024697 DOI: 10.3390/ijerph19084715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 04/04/2022] [Accepted: 04/11/2022] [Indexed: 11/16/2022]
Abstract
We examined whether post-exercise yogurt intake reduced cardiovascular strain during outdoor interval walking training (IWT) in older people during midsummer. The IWT is a training regimen repeating slow and fast walking at ~40% and ≥70% peak aerobic capacity, respectively, for 3 min each per set, ≥5 sets per day, and ≥4 days/wk. We randomly divided 28 male and 75 female older people (~73 yr), who had performed IWT ≥12 months, into a carbohydrate group (CHO-G) consuming jelly (45 g CHO, 180 kcal) and a yogurt group (YGT-G) consuming a yogurt drink (9.3 g protein, 39 g CHO, 192 kcal) immediately after daily IWT for 56 days while monitoring exercise intensity and heart rate (HR) with portable devices. We analyzed the results in 39 subjects for the CHO-G and 37 subjects for the YGT-G who performed IWT ≥ 4 days/wk, ≥60 min total fast walking/wk, and ≥4 sets of each walk/day. We found that the mean HR for fast walking decreased significantly from the baseline after the 30th day in the YGT-G (p < 0.03), but not in the CHO-G (p = 1.00). There were no significant differences in training achievements between the groups. Thus, post-exercise yogurt intake might reduce cardiovascular strain during outdoor walking training in older people.

METHODS In vitro mammary spheroid formation, flow cytometry assay on CD24-/CD44+ sub-population, ALDH activity detection, cell viability assay and western blot analysis, and in vivo tumor-initiating analysis were performed to examine the effects of Tanshinone IIA on the stemness of breast cancer cells. MiRNAs-based transcriptome sequencing and data analysis, online dataset analysis, luciferase reporter assay combined with rescuing experiments were constructed to explore the underlying mechanisms. RESULTS Tanshinone IIA attenuated the stemness of breast cancer cells, evident by downregulating the expression of stemness markers, hindering the capacity of spheroid formation, decreasing the CD24-/CD44+ sub-population in a concentration-dependent manner and reducing the tumor-initiating ability of breast cancer cells. Additionally, Tanshinone IIA enhanced adriamycin sensitivity and attenuated adriamycin resistance of breast cancer cells. Combined with miRNAs-based transcriptome sequencing assay, it was found that Tanshinone IIA downregulated miR-125b level and upregulated its target gene STARD13 (StAR-related lipid transfer protein 13) level, thus inactivating the miR-125b/STARD13 axis, which had been previously confirmed to promote breast cancer progression. Notably, miR-125b overexpression enhanced the stemness of breast cancer cells, and miR-125b overexpression or STARD13 knockdown impaired the inhibitory effects of Tanshinone IIA on the stemness of breast cancer cells. CONCLUSIONS Tanshinone IIA could attenuate the stemness of breast cancer cells via targeting the miR-125b/STARD13 axis.

Abstract
Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer mortality among women. Two thirds of patients are classified as hormone receptor positive, based on expression of estrogen receptor alpha (ERα), the main driver of breast cancer cell proliferation, and/or progesterone receptor, which is regulated by ERα. Despite presenting the best prognosis, these tumors can recur when patients acquire resistance to treatment by aromatase inhibitors or antiestrogen such as tamoxifen (Tam). The mechanisms that are involved in Tam resistance are complex and involve multiple signaling pathways. Recently, roles for microRNAs and lncRNAs in controlling ER expression and/or tamoxifen action have been described, but the underlying mechanisms are still little explored. In this review, we will discuss the current state of knowledge on the roles of microRNAs and lncRNAs in the main mechanisms of tamoxifen resistance in hormone receptor positive breast cancer. In the future, this knowledge can be used to identify patients at a greater risk of relapse due to the expression patterns of ncRNAs that impact response to Tam, in order to guide their treatment more efficiently and possibly to design therapeutic strategies to bypass mechanisms of resistance.

Downregulation of miR-497-5p Improves Sepsis-Induced Acute Lung Injury by Targeting IL2RB. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6624702. [PMID: 33954185 PMCID: PMC8057895 DOI: 10.1155/2021/6624702] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Revised: 01/29/2021] [Accepted: 03/13/2021] [Indexed: 01/04/2023]
Abstract
Introduction Acute lung injury (ALI) induced by sepsis is a process related to inflammatory reactions, which involves lung cell apoptosis and production of inflammatory cytokine. Here, lipopolysaccharide (LPS) was applied to stimulate the mouse or human normal lung epithelial cell line (BEAS-2B) to construct a sepsis model in vivo and in vitro, and we also investigated the effect of miR-497-5p on sepsis-induced ALI. Material and Methods. Before LPS treatment, miR-497-5p antagomir was injected intravenously into mice to inhibit miR-497-5p expression in vivo. Similarly, miR-497-5p was knocked down in BEAS-2B cells. Luciferase reporter assay was applied to predict and confirm the miR-497-5p target gene. Cell viability, apoptosis, the levels of miR-497-5p, IL2RB, SP1, inflammatory cytokine, and lung injury were assessed. Results In BEAS-2B cells, a significant increase of apoptosis and inflammatory cytokine was shown after LPS stimulation. In septic mice, increased inflammatory cytokine production and apoptosis in lung cells and pulmonary morphological abnormalities were shown. The miR-497-5p inhibitor transfection showed antiapoptotic and anti-inflammatory effects on BEAS-2B cells upon LPS stimulation. In septic mice, the miR-497-5p antagomir injection also alleviated ALI, apoptosis, and inflammation caused by sepsis. The downregulation of IL2RB in BEAS-2B cells reversed the protective effects of the miR-497-5p inhibitor against ALI. Conclusion In conclusion, downregulation of miR-497-5p reduced ALI caused by sepsis through targeting IL2RB, indicating the potential effect of miR-497-5p for improving ALI caused by sepsis.

Abstract
The abnormal expression and regulation of circular RNA (circRNA) is involved in the occurrence and development of a variety of tumors. The current study aimed to determine the role of circRNA_141539 in esophageal squamous cell carcinoma (ESCC). CircRNA_141539 expression in ESCC was detected via circRNA chip analysis and verified via reverse transcription-quantitative PCR. Associations between circRNA_141539, patient clinicopathological characteristics and prognosis were also statistically analyzed. Additionally, the effects of circRNA_141539 on ESCC cell proliferation and invasion were assessed. A dual-luciferase assay was performed to analyze the interaction between circRNAs, microRNAs (miRs) and mRNAs. The results revealed that circRNA_141539 was significantly up-regulated in patients with ESCC. Furthermore, high circRNA_141539 expressions were significantly associated with TNM stage, differentiation and poor prognosis, revealing high diagnostic value (P<0.05). Furthermore, circRNA_141539 overexpression promoted cell proliferation and invasion, while circRNA_141539 silencing inhibited cell proliferation and invasion (P<0.05). The dual-luciferase reporter assay identified that circRNA_141539 directly binds to miR-4469 and also revealed that cyclin-dependent kinase-3 (CDK3) was negatively regulated by miR-4469. The results indicated that circRNA_141539 served as an oncogenic factor in ESCC by sponging miR-4469 and activating CDK3 expression. circRNA_141539 may present as a novel diagnostic and prognostic biomarker and a therapeutic target for patients with ESCC.

Abstract
Breast cancer, which is the most common malignancy in women, does not form a uniform nosological unit but represents a group of malignant diseases with specific clinical, histopathological, and molecular characteristics. The increasing knowledge of the complex pathophysiological web of processes connected with breast cancercarcinogenesis allows the development of predictive and prognostic gene expressionand molecular classification systems with improved risk assessment, which could be used for individualized treatment. In our review article, we present the up-to-date knowledge about the role of miRNAs and their prognostic and predictive value in luminal A breast cancer. Indeed, an altered expression profile of miRNAs can distinguish not only between cancer and healthy samples, but they can classify specific molecular subtypes of breast cancer including HER2, Luminal A, Luminal B, and TNBC. Early identification and classification of breast cancer subtypes using miRNA expression profilescharacterize a promising approach in the field of personalized medicine. A detection of sensitive and specific biomarkers to distinguish between healthy and early breast cancer patients can be achieved by an evaluation of the different expression of several miRNAs. Consequently, miRNAs represent a potential as good diagnostic, prognostic, predictive, and therapeutic biomarkers for patients with luminal A in the early stage of BC.

Abstract
Estrogen receptors (ERs) comprise several nuclear and membrane-bound receptors with different tissue-specific functions. ERα and ERβ are two nuclear members of this family, whereas G protein-coupled estrogen receptor (GPER), ER-X, and Gq-coupled membrane estrogen receptor (Gq-mER) are membrane-bound G protein-coupled proteins. ERα participates in the development and function of several body organs such as the reproductive system, brain, heart and musculoskeletal systems. ERβ has a highly tissue-specific expression pattern, particularly in the female reproductive system, and exerts tumor-suppressive roles in some tissues. Recent studies have revealed functional links between both nuclear and membrane-bound ERs and non-coding RNAs. Several oncogenic lncRNAs and miRNAs have been shown to exert their effects through the modulation of the expression of ERs. Moreover, treatment with estradiol has been shown to alter the malignant behavior of cancer cells through functional axes composed of non-coding RNAs and ERs. The interaction between ERs and non-coding RNAs has functional relevance in several human pathologies associated with estrogen regulation, such as cancers, intervertebral disc degeneration, coronary heart disease and diabetes. In the current review, we summarize scientific literature on the role of miRNAs and lncRNAs on ER-associated signaling and related disorders.

Abstract
The relapse of breast cancer could be due to the existence of breast cancer stem cells (BCSCs). Other and our researches have indicated the suppressive roles of miR-375 in various tumors, however, its roles in breast cancer stemness remain confusing. Here, we constructed breast cancer cells with miR-375 stable overexpression via lentivirus infection. Flow cytometry, Western blot, mammosphere formation, cell colony formation and CCK8 as well as in vivo assays were performed to identify the role of miR-375 in the stemness of breast cancer cells. Luciferase reporter, RNA-Fluorescence in situ hybridization (RNA-FISH) and RNA-binding protein immunoprecipitation (RIP) assays were utilized to elucidate the mechanism whereby miR-375 exerts its effects. It was found that miR-375 not only reduced the stemness, but also decreased adriamycin resistance of breast cancer cells. These results were characterized by the decrease of BCSC rate, mammosphere-forming and tumor-initiating ability, and IC50 value of adriamycin, and weakened by JAK2 re-expression. This work indicates that miR-375 suppresses the stemness of breast cancer cells through targeting JAK2.

Abstract
Background The oncogenic roles of lncRNA THOR have been revealed in several tumors, however, its functions in breast cancer are still unclear. Material/Methods Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect THOR expression in clinical samples and the expression of stemness regulatory factors. ALDH1 assay and sphere-formation analysis were constructed to examine the stemness of cells. Cell viability assay was constructed to determine the cell proliferation capacity. In vitro RNA-RNA interaction and messenger RNA (mRNA) stability assays were performed to explore the mechanisms. Results THOR was overexpressed in triple-negative breast cancer (TNBC) compared to that in luminal A- and B-type breast cancer. THOR silencing reduced TNBC cell stemness, which was evident by the decreased sphere-formation ability, stemness marker expression and ALDH1 activity. Mechanistically, THOR directly bound to β-catenin mRNA, enhanced β-catenin mRNA stability and thus increased its expression. Furthermore, overexpression of β-catenin partially diminished THOR silencing-mediated inhibition on TNBC cell stemness. Conclusions This work proposes that THOR facilitates TNBC cell stemness through activating β-catenin signaling.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that can post-transcriptionally regulate the genes involved in critical cellular processes. The aberrant expressions of oncogenic or tumor suppressor miRNAs have been associated with cancer progression and malignancies. This resulted in the dysregulation of signaling pathways involved in cell proliferation, apoptosis and survival, metastasis, cancer recurrence and chemoresistance. In this review, we will first (i) provide an overview of the miRNA biogenesis pathways, and in vitro and in vivo models for research, (ii) summarize the most recent findings on the roles of microRNAs (miRNAs) that could potentially be used for miRNA-based therapy in the treatment of breast cancer and (iii) discuss the various therapeutic applications.

[PMID: 32711380 PMCID: PMC7381513 DOI: 10.1016/j.omtn.2020.06.018] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 04/20/2020] [Accepted: 06/22/2020] [Indexed: 01/01/2023]
Abstract
Transcription factor Yin Yang 1 (YY1) is upregulated in multiple tumors and plays essential roles in tumor proliferation and metastasis. However, the function of YY1 in breast cancer stemness remains unclear. Herein, we found that YY1 expression was negatively correlated with the overall survival and relapse-free survival of breast cancer patients and positively correlated with the expression of stemness markers in breast cancer. Overexpression of YY1 increased the expression of stemness markers, elevated CD44+CD24− cell sub-population, and enhanced the capacity of cell spheroid formation and tumor-initiation. In contrast, YY1 knockdown exhibited the opposite effects. Mechanistically, YY1 decreased microRNA-873-5p (miR-873-5p) level by recruiting histone deacetylase 4 (HDAC4) and HDAC9 to miR-873-5p promoter and thus increasing the deacetylation level of miR-873-5p promoter. Sequentially, YY1 activated the downstream PI3K/AKT and ERK1/2 pathways, which have been confirmed to be suppressed by miR-873-5p in our recent work. Moreover, the suppressed effect of YY1/miR-873-5p axis on the stemness of breast cancer cells was partially dependent on PI3K/AKT and ERK1/2 pathways. Finally, it was found that the YY1/miR-873-5p axis is involved in the chemoresistance of breast cancer cells. Our study defines a novel YY1/miR-873-5p axis responsible for the stemness of breast cancer cells.

Hepatocyte nuclear factor-1β suppresses the stemness and migration of colorectal cancer cells through promoting miR-200b activity. Mol Carcinog 2020; 59:989-999. [PMID: 32495507 DOI: 10.1002/mc.23229] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 03/06/2020] [Accepted: 05/20/2020] [Indexed: 01/23/2023]
Abstract
The effects of hepatocyte nuclear factors (HNFs) have been established in various tumors; however, the roles of HNF-1β in colorectal cancer progression are never been found. In the present study, HNF-1β expression was initially detected in clinical tissue samples and online datasets and HNF-1β was found to be highly expressed in colorectal cancer tissues. In addition, a positive correlation existed between HNF-1β expression and the overall survival of patients with colorectal cancer. In vitro and in vivo experiments revealed that HNF-1β suppressed the stemness and migration of colorectal cancer cells. Combined with microRNAs (miRNAs) based on transcriptome-sequencing analysis, mechanistic studies showed that HNF-1β directly bound to miR-200b promoter and thus promoted miR-200b expression, this HNF-1β/miR-200b resulted in the downregulation of the expression of miR-200b downstream effectors. Furthermore, HNF-1β inhibits the stemness and migration of colorectal cancer cells through miR-200b. This study reveals a novel HNF-1β/miR-200b axis responsible for the stemness of colorectal cancer cells.

The miRNA-149-5p/MyD88 axis is responsible for ursolic acid-mediated attenuation of the stemness and chemoresistance of non-small cell lung cancer cells. ENVIRONMENTAL TOXICOLOGY 2020; 35:561-569. [PMID: 31855318 DOI: 10.1002/tox.22891] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 12/04/2019] [Accepted: 12/08/2019] [Indexed: 06/10/2023]
Abstract
Although the inhibitory roles of ursolic acid (UA) have been established in various tumors, its effects on the stemness of non-small cell lung cancer (NSCLC) cells are still unclear. Here, we constructed NSCLC cells with paclitaxel resistance (A549-PR) and showed that A549-PR exhibited a remarkably stronger stemness than the parental A549 cells, which is evident by the increase of spheroid formation capacity, stemness marker expression, and ALDH1 activity. Additionally, UA significantly reduced the stemness and paclitaxel resistance of A549-PR cells. Mechanistic investigations revealed that UA inhibited the miR-149-5p/MyD88 signaling, which is responsible for UA-mediated effects on the stemness of A549-PR cells. Notably, miR-149-5p/MyD88 axis promoted the stemness of A549 cells, while inhibition of this axis attenuated the stemness of A549-PR cells. Therefore, these results suggest that UA could attenuate the stemness and chemoresistance of NSCLC cells through targeting miR-149-5p/MyD88 axis.

Abstract
The promoting effects of transcriptional factor Yin Yang 1 (YY1) have been confirmed in various tumors, however, its roles in ovarian cancer (OC) progression are still unclear. Here, Kaplan-Meier Plotter analysis was used to determine the correlation between YY1 expression and the survival of OC patients. It was found that YY1 expression was negatively correlated with the overall survival, progression-free survival and post-progression survival of OC patients. Functional experiments indicated that overexpression of YY1 facilitated the stemness of OC cells, while YY1 knockdown reduced it. MiRNAs-based RNA-sequencing analysis showed that miR-99a was the mostly upregulated miRNA in RNA extracted from OC cells with YY1 knockdown. Mechanistic studies revealed that YY1 recruited (Histone deacetylase) HDAC5 to the promoter of miR-99a, and subsequently enhanced miR-99a deacetylation level and decreased miR-99a level. Additionally, overexpression of miR-99a or knockdown of HDAC5 attenuated the promoting effects of YY1 on the stemness of OC cells. This work firstly indicated a novel YY1/miR-99a axis, which promotes the stemness of OC cells.

Abstract
The bromodomain protein BRD4 exerts carcinogenic effects in many cancers. However, its roles in glioma occurrence are still confused. Here, it is found that BRD4 expression is increased in glioma tissues and negatively correlated with the overall survival of glioma patients. We construct cellular experiments indicating that BRD4 promotes glioma cell stemness by analyzing ALDH1 activity, master stemness regulator expression, and sphere formation ability. Mechanistically, BRD4 knockdown triggers a switch of miR-142-5p promoter methylation, which targets Wnt3a and thus further inactivates Wnt/β-catenin signaling. Importantly, inhibition of miR-142-5p or reactivation of Wnt/β-catenin signaling rescues the inhibition of BRD4 knockdown on glioma cell stemness. As a result, these results not only indicate an unforeseen connection between BRD4, miR-142-5p, and Wnt/β-catenin signaling, but also reveal a promising epigenetic-based therapeutic strategy that might be explored for glioma patients.

Thorac Cancer 2020; 11:394-407. [PMID: 31901156 PMCID: PMC6996984 DOI: 10.1111/1759-7714.13283] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Revised: 11/25/2019] [Accepted: 11/29/2019] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND TP73 antisense RNA 1 (TP73-AS1) is a long noncoding RNA which has been shown to be involved in the progression of multiple malignant tumors. Previous studies have demonstrated the oncogenic role of TP73-AS1 in breast cancer. However, its molecular mechanism remains largely unknown in breast tumorigenesis. METHODS Expression of TP63-AS1, miRNA-125a-3p (miR-125a) and metadherin (MTDH) was detected by real-time quantitative PCR and western blotting. The malignancy was evaluated by cell counting kit 8 (CCK-8), transwell assays, flow cytometry and western blotting. The target binding was confirmed by dual luciferase reporter assay. Xenograft tumor model was performed to detect tumor growth in vivo. RESULTS Expression of TP73-AS1 was higher in breast cancer tissues and cell lines. Biologically, its knockdown could promote cell apoptosis rate, and inhibit proliferative capacity, migration and invasion ability in HCC-70 and MB231 cells, accompanied with higher cleaved caspase 3 level and lower Ki67, N-cadherin and Vimentin level. Moreover, TP73-AS1 downregulation restrained the tumor growth of HCC-70 cells in vivo. Mechanically, TP73-AS1 functioned as a molecular "sponge" for miR-125a to modulate MTDH, a downstream target of miR-125a. Intriguingly, both miR-125a overexpression and MTDH silencing exerted a tumor-suppressive effect in the malignant progression of HCC-70 and MB231 cells, which was counteracted by TP73-AS1 upregulation and miR-125a downregulation, respectively. CONCLUSION Knockdown of TP73-AS1 inhibited cell proliferation, migration and invasion, but facilitated apoptosis in breast cancer cells in vitro through targeting miR-125a and upregulating MTDH, suggesting a novel TP73-AS1/miR-125a/MTDH pathway in the malignant progression of breast cancer.

Abstract
BACKGROUND Tamoxifen (TAM) is the first-line drug for estrogen receptor-positive (ER+) breast cancer (BC) treatment. However, its resistance is a main obstacle in clinical practice. Thus, new therapeutic agents are urgently needed to fight TAM resistance. MATERIAL AND METHODS Here, we constructed TAM-resistant ER+BC cells with TAM resistance, named MCF-7-R. Western blot, quantitative real-time PCR (qRT-PCR), ALDH1 activity analysis, and spheroid-forming detection were used to detect the stemness of cells and the effects of napabucasin (NP) on BC cell stemness. Cell counting kit-8 (CCK8) assay was used to evaluate the effects of NP on cell viability. RESULTS MCF-7-R cells exhibited higher stemness compared with the parental MCF-7 cells, which was evident by the increased spheroid formation ability at diluted concentration, aldehyde dehydrogenase (ALDH) activity, and expression of stemness critical biomarkers (Oct4, Nanog, and Sox2). Additionally, it was found that napabucasin (NP) specifically killed MCF-7-T cells, characterized by remarkably decreased IC₅₀ value. Notably, NP reduced MCF-7-R cell stemness, which was evident as the decreased stemness marker expression, spheroid-forming capacity, and ALDH1 activity. Importantly, NP attenuated TAM resistance of MCF-7-R cells and enhanced sensitivity of MCF-7 cells to TAM. Mechanistic study showed that NP inhibited STAT3 activation, and overexpression of STAT3 rescued NP-mediated inhibition of the stemness-like characteristics of MCF-7-R cells. CONCLUSIONS NP might be used as an adjuvant therapy for ER+ BC patients with TAM resistance.

Abstract
Background: Breast cancer is the most common female cancer with considerable metastatic potential, which urges the need for developing novel potential drug candidate to inhibit tumor metastasis. Signal transducer and activator of transcription 3 (Stat3) have critical roles in cancer growth and metastasis and have been confirmed as a promising anticancer target. Here, we report our finding with pectolinarigenin, a flavonoid compound isolated from the aerial parts of Cirsium chanroenicum. Methods: The role of Pec. in cell proliferation, cell apoptosis, and cell migration and invasion in three breast cancer cells (4T1, MDA-MB-231, MCF-7) was investigated. Cell proliferation was determined by MTT assay, cell apoptosis was determined by flow cytometry, and protein expression was detected by western blotting. Tumor xenograft mice model and breast tumor metastasis model in vivo were built to further assess the effects of Pec. on 4T1 cells. Results: Intraperitoneal administrations of pectolinarigenin significantly inhibited breast cancer metastasis to lungs without affecting the tumor growth of incubated 4T1 breast cancer cells. Pectolinarigenin could also recruit CD8+ T cells to mediate tumor immune response. Furthermore, pectolinarigenin markedly impaired cancer cell migration and invasion by down-regulating phosphorylated-Stat3, and expression of matrix metalloproteinase (MMP)-2, MMP-9, while up-regulating the expression of TIMP2. We also found that pectolinarigenin inhibited breast cancer cell proliferation and induced apoptosis via mitochondrial-related apoptosis pathway, reduced mitochondrial membrane potential and the expression of Bcl-2, increased expression of Bax, and cleaved caspase-3 as well as disturbed the ROS generation. Conclusions: Pectolinarigenin might potentially be a candidate for metastasis of breast cancer by mediating Stat3 pathway.

MicroRNA-125a-3p affects smooth muscle cell function in vascular stenosis. J Mol Cell Cardiol 2019; 136:85-94. [PMID: 31499051 DOI: 10.1016/j.yjmcc.2019.08.014] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2019] [Revised: 08/04/2019] [Accepted: 08/31/2019] [Indexed: 11/21/2022]
Abstract
AIMS Many studies have indicated that microRNAs are closely related to the process of peripheral arterial disease (PAD). Previously, we found that microRNA-125a-3p (miR-125a-3p) in restenotic arteries after interventional therapy of lower extremity vessels was notably decreased compared with that of normal control arteries. However, its role in the development of vascular stenosis is not yet clearly understood. The purpose of this study was to investigate the expression, regulatory mechanism and function of miR-125a-3p in the process of vascular stenosis. METHODS AND RESULTS Quantitative reverse-transcription polymerase chain reaction assays indicated that miR-125a-3p in restenotic arteries after interventional therapy was significantly lower than that in normal control arteries. Immunofluorescence and in situ hybridization co-staining assays in arterial sections demonstrated that miR-125a-3p was mainly expressed in the medial smooth muscle layer. Transfection of miR-125a-3p mimics into cultured vascular smooth muscle cells (VSMCs) effectively inhibited cell proliferation and migration. Then, western blot and luciferase activity assays showed that recombinant human mitogen-activated protein kinase 1 (MAPK1) was a functional target of miR-125a-3p and was involved in miR-125a-3p-mediated cell effects. Finally, the lentiviral infection of miR-125a-3p in balloon-injured rat carotid vascular walls showed that miR-125a-3p overexpression significantly reduced the probability of neointimal membrane production. CONCLUSIONS miR-125a-3p can effectively inhibit the function of VSMCs and the occurrence of vascular stenosis by targeting MAPK1. This study introduces a new molecular mechanism of PAD. We show that regulation of the miR-125a-3p level has the potential to provide a new treatment for PAD and other proliferative vascular diseases.

[PMID: 31254127 DOI: 10.1007/s10456-019-09675-z] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2019] [Accepted: 06/24/2019] [Indexed: 01/09/2023]
Abstract
BACKGROUND PIN2/TRF1-interacting telomerase inhibitor 1 (PinX1) is a tumor suppressor in various tumors. However, the molecular mechanism underlying PinX1's role in cancer development and progression remains unclear. In this study, we aimed to uncover the new molecular mechanism and role of PinX1 in renal cell carcinoma (RCC) progression. METHODS We used miRNA microarray to detect the different expressed miRNAs upon PinX1 knockdown. Chromatin immunoprecipitation and Luciferase reporter assays were taken to identify the molecular mechanism of PinX1 in regulating mir-125-3p. In situ hybridization was performed to analyze the expression of mir-125a-3p in RCC using tissue microarray. The correlations between the mir-125a-3p expression level and clinicopathological features were evaluated using the χ2 test. The role and molecular mechanism of PinX1 in RCC angiogenesis were investigated through a series of in vitro and in vivo experiments. RESULTS In this study, we discovered a new molecular mechanism of PinX1, in which PinX1 transcriptionally activated mir-125a-3p expression, thereby inhibiting the expression of vascular endothelial growth factor (VEGF), which is the target gene of mir-125a-3p. PinX1 also repressed tumor angiogenesis by increasing the mir-125a-3p expression in renal cancer. Moreover, the loss of mir-125a-3p expression was manifested in patients with RCC, and low miR-125a-3p levels correlated with poor survival of these patients. CONCLUSIONS PinX1 represses renal cancer angiogenesis through mir-125a-3p/VEGF signal pathway. The miR-125a-3p may be a candidate clinical prognostic marker and a novel therapeutic target in RCC.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that play a wide variety of critical roles in different biological processes by post-transcriptionally regulating gene expression. They access diverse regulatory pathways during various stages of cellular differentiation, growth, and apoptosis, and can contribute to both normal and diseased functions. One important family of miRNAs involved in these functions is the miR-125 family (miR-125a and miR-125b). Investigations have been made to increasingly uncover the mechanisms by which the miR-125 family regulates normal homeostasis and growth in a variety of cell types including immune cells, and how dysregulation of miR-125a and miR-125b can lead to disease pathogenesis and tumorigenesis. In this review, we summarize what is currently known about miR-125a and miR-125b, mainly focusing on their roles in immune cell development and function as well as tumor suppression and promotion.

Abstract
The critical roles of TGFBR2/Smad2 signaling have been established in LPS-induced sepsis, however, the underlying mechanisms by which TGFBR2/Smad2 signaling was regulated in LPS-induced sepsis are still confused. Here, miRNA-based on RNA-sequencing dataset revealed that miR-145 was significantly decreased in human umbilical vein endothelial cells (HUVECs) following LPS treatment. Bioinformatics, luciferase reporter and RNA immune co-precipitation (RIP) assays showed that miR-145 could directly target TGFBR2 and thus inactivated TGFBR2/Smad2 axis. On the contrary, luciferase reporter and chromatin immunoprecipitation (ChIP) analysis showed that Smad2 could directly bind to DNA methyltransferase 1 (DNMT1), the upregulation of which led to miR-145 promoter hypermethylation and downregulation of miR-145 expression, conversely promoting TGFBR2 expression. Notably, knockdown of TGFBR2 partially rescued the inhibition on miR-145 expression induced by LPS treatment. Additionally, we found that knockdown of TGFBR2 or overexpression of miR-145 attenuated LPS-induced sepsis and prolonged the overall survival of septic mice. Furthermore, TGFBR2 overexpression abrogated miR-145 overexpression-mediated attenuation on LPS-induced sepsis. Our results demonstrate the TGFBR2/SMAD2/DNMT1/miR-145 negative regulatory loop is responsible for LPS-induced sepsis.

Abstract
The really interesting new gene (RING) finger protein 8 (RNF8) is a central factor in DNA double strand break (DSB) signal transduction. DSB damage is the most toxic type of DNA damage to cells and is related to genomic instability. Multiple roles for RNF8 have been identified in DNA damage response as well as in other functions, such as telomere protection, cell cycle control and transcriptional regulation. These functions are closely correlated to tumorigenesis and cancer progression. Indeed, deficiency of RNF8 caused spontaneous tumorigenesis in a mouse model. Deciphering these mechanisms of RNF8 may shed light on strategies for cancer treatment. In this review, we summarize the current understanding of both classical and nonclassical functions of RNF8, and discuss its roles in the pathogenesis and progression of tumor.

Abstract
In recent study, microRNAs have various important functions in diverse biological
processes and progression of cancer. In human breast cancer, microRNA-22 has been reported
to be downregulated. However, molecular mechanism of microRNA-22 in breast cancer
progression and chemosensitivity has not been well studied. In our study, these results
demonstrated that microRNA-22 expression levels were significantly reduced in 40 pairs of
human breast cancer tissues when compared to normal tissues. Enforced expression of
microRNA-22 inhibited activity of cell proliferation and cell migration in breast cancer
cells. Furthermore, microRNA-22 targeted NRAS proto-oncogene, GTPase (NRAS) in breast
cancer cells. The expression levels of NRAS in human clinical specimens were higher in
breast cancer tissues when compared to normal tissues. Moreover, microRNA-22 sensitized
breast cancer cells to paclitaxel by regulation of NRAS. Our results then demonstrated
that microRNA-22 functioned as a tumor suppressor microRNA and indicated potential
application for the diagnosis and treatment of cancer in the future.

Transcriptional factor six2 promotes the competitive endogenous RNA network between CYP4Z1 and pseudogene CYP4Z2P responsible for maintaining the stemness of breast cancer cells. J Hematol Oncol 2019; 12:23. [PMID: 30832689 PMCID: PMC6399913 DOI: 10.1186/s13045-019-0697-6] [Citation(s) in RCA: 48] [Impact Index Per Article: 9.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2018] [Accepted: 01/13/2019] [Indexed: 12/22/2022] Open
Abstract
Background The expression of CYP4Z1 and the pseudogene CYP4Z2P has been shown to be specifically increased in breast cancer by our group and others. Additionally, we previously revealed the roles of the competitive endogenous RNA (ceRNA) network mediated by these genes (ceRNET_CC) in breast cancer angiogenesis, apoptosis, and tamoxifen resistance. However, the roles of ceRNET_CC in regulating the stemness of breast cancer cells and the mechanisms through which ceRNET_CC is regulated remain unclear. Methods Transcriptional factor six2, CYP4Z1-3′UTR, and CYP4Z2P-3′UTR were stably overexpressed or knocked down in breast cancer cells via lentivirus infection. ChIP-sequencing and RNA-sequencing analysis were performed to reveal the mechanism through which ceRNET_CC is regulated and the transcriptome change mediated by ceRNET_CC. Clinical samples were used to validate the correlation between six2 and ceRNET_CC. Finally, the effects of the six2/ceRNET_CC axis on the stemness of breast cancer cells and chemotherapy sensitivity were evaluated by in vitro and in vivo experiments. Results We revealed that ceRNET_CC promoted the stemness of breast cancer cells. Mechanistically, six2 activated ceRNET_CC by directly binding to their promoters, thus activating the downstream PI3K/Akt and ERK1/2 pathways. Finally, we demonstrated that the six2/ceRNET_CC axis was involved in chemoresistance. Conclusions Our results uncover the mechanism through which ceRNET_CC is regulated, identify novel roles for the six2/ceRNET_CC axis in regulating the stemness of breast cancer cells, and propose the possibility of targeting the six2/ceRNET_CC axis to inhibit breast cancer stem cell (CSC) traits.

Abstract
This study aims to explore the roles of miR-145/TGFBR2 axis in sepsis-induced acute lung injury. Here, RNA-sequencing assay showed that miR-145 was significantly decreased in exosomes from sepsis patient blood samples. And miR-145 was decreased but TGFBR2 was increased in LPS-treated mice lung tissues or BEAS-2B cells in a time-dependent manner. Mechanistically, TGFBR2 was identified as a direct target of miR-145 and the downstream effector Smad3 was also suppressed in BEAS-2B cells with miR-145 overexpression. Pre-injection or post-injection of miR-145 agomir following LPS treatment attenuated LPS-induced inflammation, characterized as the downregulation of IL-2 and TNF-α secretion and ameliorate sepsis, and prolonged the overall survival of septic mice with lung injury. Additionally, TGFBR2 overexpression partially abrogated miR-145-mediated inhibition on LPS-induced inflammation and sepsis-induced acute lung injury. Importantly, TGF-β (Transforming growth factor-β) and miR-145 level displayed a negative correlation in sepsis patients. Thus, these results suggest that miR-145 could ameliorate sepsis-induced lung injury via inhibiting TGFBR2 signaling.

Abstract
Limonin has been shown to exert anti-inflammatory effects, however, its roles in tumor progression remain unclear. This work aims to investigate the roles and related mechanism of limonin in the stemness of breast cancer cells. Here, we found that limonin attenuated the stemness of breast cancer cells in a concentration-dependent manner, evident by the decreasing the capacity of cell spheroid formation, expression of stemness markers and ALDH1 activity, whereas had no toxicity on non-tumorigenic cells. Additionally, limonin enhanced adriamycin sensitivity of breast cancer cells and attenuated adriamycin resistance in adriamycin-resistant breast cancer cells. Mechanistically, limonin decreased MIR216A methylation level and thus increased miR-216a-3p expression. Furthermore, miR-216a-3p could directly bind to WNT3A and thus inactivated Wnt/β-catenin pathway. Therefore, our results indicate that limonin could attenuate the stemness and chemoresistance via inhibiting MIR216A methylation and subsequently suppressing Wnt/β-catenin pathway.

MiR-873/PD-L1 axis regulates the stemness of breast cancer cells. EBioMedicine 2019; 41:395-407.

Abstract
Background Breast cancer stem cells have self-renewal capability and are resistant to conventional chemotherapy. PD-L1 could promote the expression of stemness markers (OCT4 and Nanog) in breast cancer stem cells. However, the mechanisms by which PD-L1 regulates the stemness of breast cancer cells and PD-L1 is regulated in breast cancer cells are still unclear. Methods Lentivirus infection was used to construct stable cell lines. The correlation between PD-L1 and stemness markers expression was evaluated in clinical samples. Additionally, luciferase reporter assay combined with RNA-Fluorescence in situ hybridization (RNA-FISH) and RNA-binding protein immunoprecipitation (RIP) assays were used to verify the direct binding of miR-873 on PD-L1. Furthermore, flow cytometry, mammosphere formation combined with nude mouse tumor xenograft model were carried out to examine the effects of miR-873/PD-L1 axis on the stemness of breast cancer cells. Finally, MTT assay was performed to determine the effects of miR-873/PD-L1 axis on drug resistance. Findings PD-L1 expression was positively correlated with the expression of stemness markers, and overexpression of PD-L1 contributed to chemoresistance and stemness-like properties in breast cancer cells via activating PI3K/Akt and ERK1/2 pathways. Mechanistically, miR-873 inhibited PD-L1 expression through directly binding to its 3′-untranslated region (UTR), and miR-873 attenuated the stemness and chemoresistance of breast cancer cells which was dependent on PD-L1 and the downstream PI3K/Akt and ERK1/2 signaling. Notably, the promotion of PD-L1 on the stemness and chemoresistance was enhanced by recombinant PD-1 (rPD-1), this effect was attenuated by PD-1/PD-L1 inhibitor. Interpretation miR-873/PD-L1 regulatory axis might serve as a therapeutic target to enhance the chemo-sensitivity and eliminate the stemness of breast cancer cells. Fund This work was supported by the National Nature Science Foundation of China, No. 81702957, China Postdoctoral Science Foundation, No. 2017M620230, the Postdoctoral Research Funding Scheme of Jiangsu Province (2017), No. 1701197B, and the Priority Academic Program Development (PAPD) of Jiangsu Higher Education Institutions. A critical role of PD-L1 in stemness and chemoresistance is proposed. A negative miR-873/PD-L1 interaction was identified in breast cancer cells. The mechanisms of miR-873/PD-L1 in stemness and chemoresistance were studied. The results provide new insights for breast cancer progression and treatment.

Abstract
Background The roles and related mechanism of miR-376a in breast cancer cell progression are unclear. Methods Kaplan-Meier plotter analysis was used to analyze the correlation between miR-376a and the overall survival (OS) of breast cancer patients. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was performed to detect miR-376a level in breast cancer cells. Cell viability, transwell migration and invasion, and cell apoptosis were constructed to investigate the effects of miR-376a on breast cancer cells. Luciferase reporter and RNA immunoprecipitation (RIP) were used to explore the targeting of miR-376a on NRP-1. Results miR-376a expression was positively correlated with the overall survival of breast cancer patients, and significantly decreased in breast cancer cells. Functionally, miR-376a over-expression suppressed cell proliferation, migration and invasion, and promoted cells apoptosis. Additionally, miR-376a could directly target NRP-1 and exerted its effect through NRP-1. Conclusion miR-376a could suppress breast cancer cell progression via directly targeting NRP-1.

Abstract
OBJECTIVES This work aims to reveal the roles and related mechanisms of RNA binding protein PUM2 in osteosarcoma progression. MATERIALS AND METHODS Transcriptome analysis based on RNA sequencing data, real-time quantitative PCR (RT-qPCR), and western blot analysis were used to detect the expression of RBPs and miRNAs in OS and normal adjacent tissues, and the correlation between them in OS tissues. RT-qPCR, western blot, cell viability, transwell migration, tumour spheres formation and in vivo tumour formation assays were used to examine the effects of RBP PUM2 on OS progression. Additionally, RNA immunoprecipitation (RIP) assay combined with RNA sequencing was performed to determine the binding site of RBP PUM2 on STARD13 3'UTR. Luciferase reporter and RIP assays were used to confirm the binding of miRNAs or PUM2 on STARD13 3'UTR. RESULTS PUM2 and STARD13 expression was significantly decreased in OS tissues, and positively correlated. Overexpression of PUM2 or STARD13 3'UTR inhibited OS cells proliferation, migration, and stemness. Mechanistically, PUM2 competitively bound to STARD13 3'UTR with miR-590-3p and miR-9. The inhibition of PUM2 on OS cells progression was attenuated by STARD13 knockdown or related miRNAs overexpression. CONCLUSION PUM2 suppresses OS progression via partly and competitively binding to STARD13 3'UTR with miRNAs.

Curcumol Exerts Anticancer Effect in Cholangiocarcinoma Cells via Down-Regulating CDKL3. Front Physiol 2018; 9:234.

Abstract
Curcumol is the major component extracted from root of Rhizoma Curcumae. Recent studies have shown that curcumol exerts therapeutic effects against multiple conditions, particularly cancers. However, the therapeutic role and mechanism of curcumol against cholangiocarcinoma cells are still unclear. In our current research, we tested the effect of curcumol in cholangiocarcinoma cells, and using two-dimensional electrophoresis, proteomics and bioinformatics, we identified cyclin-dependent kinase like 3 (CDKL3) as a potential target for curcumol. We have demonstrated that curcumol can evidently suppress growth and migration of cholangiocarcinoma cells. Furthermore, curcumol could significantly block the cell cycle progression of the cholangiocarcinoma cells. These effects could be largely attributed to the inhibition of CDKL3 by curcumol. Further studies have recapitulated the oncogenic role of CDKL3 in that knockdown of CDKL3 by lentiviral mediated transfection of shRNA against CDKL3 also led to a significant inhibition on cell proliferation, migration, invasion, and cell cycle progression. Given the high level of CDKL3 expression in human cholangiocarcinoma tissues and cell lines, we speculated that CDKL3 may constitute a potential biological target for curcumol in cholangiocarcinoma.

Abstract
OBJECTIVES To study the roles and mechanisms of HuR in cancer stem cell maintenance of lung cancer. RESULTS HuR expression was increased in tumor spheres of lung cancer cells. Knockdown of HuR suppressed spheroid formation and size, inhibited the expression of stemness-related marker, Oct4, Nanog and ALDH in lung cancer cells. Importantly, HuR and CDK3 expressions were increased in lung cancer tissues compared with normal adjacent tissues, and positively correlated. Mechanistically, HuR directly bound to CDK3, and increased CDK3 mRNA stability and expression. Additionally, miR-873 or miR-125a-3p attenuated the promotion of HuR on CDK3 expression and lung cancer stemness. Furthermore, HuR facilitated lung cancer stemness dependent on CDK3 expression. miR-873 or miR-125a-3p level was negatively correlated with HuR and CDK3 expression levels in lung cancer tissues. CONCLUSIONS HuR facilitates lung cancer stemness via regulating miR-873/CDK3 and miR-125a-3p/CDK3 axis.
