Abstract
Background Glioblastoma (GBM) is an aggressive adult brain tumor that poses a huge threat to people's health. Previous studies have shown that microRNAs (miRNAs) are important regulators in the progression of GBM. However, the role of miR-448 in GBM remains largely unknown. Therefore, the regulatory mechanism of miR-448 in the development of GBM is elucidated in this study. Methods The protein and mRNA expressions of miR-448 and ROCK1 were measured by Western blot analysis and RT-qPCR. Cell proliferation, migration, and invasion were detected by CCK-8 assay and Transwell assay. The relationship between miR-448 and ROCK1 was probed by luciferase reporter assay. Results miR-448 expression was downregulated in GBM tissues and cells. And poor clinical outcomes of GBM patients were related to miR-448 downregulation. Functionally, overexpression of miR-448 restrained cell viability, migration, and invasion in GBM. Additionally, miR-448 reduced ROCK1 expression by binding to its 3'-UTR. Moreover, knockdown of ROCK1 inhibited the progression of GBM. Furthermore, overexpression of ROCK1 abolished the antitumor effect of miR-448 in GBM. Conclusion miR-448 restrained cell viability, invasion, and migration in GBM by inhibiting ROCK1 expression.

Abstract
Hepatocellular carcinoma (HCC) is a highly lethal type of malignancies that possesses great loss of life safety to human beings worldwide. However, few effective means of curing HCC exist and its specific molecular basis is still far from being fully elucidated. Activation of nuclear factor kappa B (NF-κB), which is often observed in HCC, is considered to play a significant part in hepatocarcinogenesis and development. The emergence of regulatory non-coding RNAs (ncRNAs), particularly microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), is a defining advance in cancer biology, and related research in this branch has yielded many diagnostic and therapeutic opportunities. Recent studies have suggested that regulatory ncRNAs act as inhibitors or activators in the initiation and progression of HCC by targeting components of NF-κB signaling or regulating NF-κB activity. In this review, we attach importance to the role and function of regulatory ncRNAs in NF-κB signaling of HCC and NF-κB-associated chemoresistance in HCC, then propose future research directions and challenges of regulatory ncRNAs mediated-regulation of NF-κB pathway in HCC.

[PMID: 34399695 PMCID: PMC8365892 DOI: 10.1186/s12871-021-01423-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Accepted: 07/27/2021] [Indexed: 02/27/2023] Open
Abstract
BACKGROUND Cerebral ischemia/reperfusion injury (CIRI) is a complication of surgical procedure associated with high mortality. The protective effect of dexmedetomidine (DEX) on CIRI has been explored in previous works, yet the underlying molecular mechanism remains unclear. Our study explored the protective effect of DEX and its regulatory mechanism on CIRI. METHODS A CIRI rat model was established using middle cerebral artery occlusion (MCAO). Neurological deficit scores for rats received MCAO modeling or DEX treatment were measured. Cerebral infarction area of rats was detected by TTC staining, while damage of neurons in hippocampal regions of rats was determined by hematoxylin-eosin (HE) staining. Apoptosis rate of neurons in hippocampal regions was examined by TUNEL staining. The dual-luciferase assay was performed to detect the binding of microRNA-214 (miR-214) to Rho-associated kinase 1 (ROCK1). RESULTS DEX treatment significantly reduced infarction area of MCAO rats and elevated miR-214 expression. Injection of miR-214 inhibitor attenuated the effect of DEX in MCAO rats by increasing the area of cerebral infarction in rats and apoptosis rate of hippocampal neurons. ROCK1 was targeted and negatively regulated by miR-214. The overexpression of ROCK1 led to activation of NF-κB to aggravate CIRI. CONCLUSION Therapeutic effects of DEX on CIRI was elicited by overexpressing miR-214 and impairing ROCK1 expression and NF-κB activation. Our finding might provide novel insights into the molecular mechanism of DEX in rats with CIRI.

Abstract
BACKGROUND Acute respiratory distress syndrome (ARDS) causes substantial mortalities. Alveolar epithelium is one of the main sites of cell injuries in ARDS. As an important kind of microRNAs (miRNAs), microRNA-145 (miR-145) has been studied in various diseases, while its role in ARDS has not been investigated. METHODS Lipopolysaccharide (LPS) was intratracheally instilled to establish a rat ARDS model. Cytokines from bronchoalveolar lavage fluid (BALF) were measured using rat tumor necrosis factor-α and interleukin-6 enzyme-linked immunosorbent assay kits (R&D Systems), and the pathological structures were evaluated using hematoxylin and eosin (H&E) staining and transmission electron microscope; the lung miR-145 messenger RNA (mRNA) was detected using quantitative polymerase chain reaction. Bioinformatics focused on the target genes and possible pathways of gene regulation. RESULTS A rat model of LPS-induced ARDS was successfully established. The miR-145 was down-regulated in the LPS-induced ARDS lung, and mitochondrial dysfunction was observed in alveolar epithelial cells, most obviously at 72 hours after LPS. TargetScan and miRDB databases were used to predict the target genes of miR-145. A total of 428 overlapping genes were identified, seven genes were associated with mitochondrial function, and Ogt, Camk2d, Slc8a3, and Slc25a25 were verified. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were enriched in the mitogen-activated protein kinase (MAPK) signaling pathway, and Gene Ontology (GO) biological process was mainly enriched in signal transduction and transcription regulation. CONCLUSIONS The miR-145 is down-regulated in LPS-induced ARDS, and affects its downstream genes targeting mitochondrial functions.

Abstract
Globally, lung cancer is known as a major cause of cancer-associated death and non-small-cell lung cancer (NSCLC) accounts for majority of all cases. Growing evidence has emerged that long non-coding RNAs (lncRNAs) act as vital regulatory molecules in various malignancies. Nevertheless, the function of SLCO4A1 antisense RNA 1(SLCO4A1-AS1) in NSCLC is vague. This study intended to investigate the biological role and probable regulatory mechanism of SLCO4A1-AS1 in NSCLC. qRT-PCR revealed that SLCO4A1-AS1 level was upregulated in NSCLC. Function assays manifested that silence of SLCO4A1-AS1 attenuated NSCLC cell proliferation, migration and invasion but promoted NSCLC cell apoptosis. Furthermore, we disclosed that SLCO4A1-AS1 activated NF-κB pathway in NSCLC, and that IKKα, an NF-κB pathway-related gene, possessed an enhanced level in NSCLC tissues and cells. Importantly, miR-223-3p bound with SLCO4A1-AS1 and IKKα. Further, SLCO4A1-AS1 competitively bound with miR-223-3p to increase IKKα expression, thereby activating NF-κB signaling pathway. In conclusion, SLCO4A1-AS1 drove NSCLC progression by activating NF-κB signaling pathway via sponging miR-223-3p to enhance IKKα expression. Thus, SLCO4A1-AS1 might be a promising biomarker for NSCLC treatment.

Abstract
Aim Circular RNAs (circRNAs) play important roles in the progression of human cancers. circRNA nuclear receptor interacting protein 1 (circNRIP1) has been reported to play as an oncogene in gastric cancer. However, the mechanism underlying circNRIP1 in gastric cancer progression is far from understood. Patients and Methods Forty-five gastric cancer patients were recruited and overall survival of patients was analyzed. Gastric cancer cell lines MGC-803 and AGS cells were cultured for study in vitro. The expression levels of circNRIP1, microRNA (miR)-182 and rho-associated protein kinase 1 (ROCK1) were detected by quantitative real-time polymerase chain reaction or Western blot. Cell migration, invasion, cell cycle distribution and apoptosis were determined by transwell, flow cytometry and Western blot assays, respectively. The target association between miR-182 and circNRIP1 or ROCK1 was assessed by luciferase reporter assay and RNA immunoprecipitation. Results circNRIP1 expression was enhanced in gastric cancer tissues and cells and high expression of circNRIP1 indicated poor survival of patients. Knockdown of circNRIP1 suppressed cell migration and invasion, arrested cell cycle at G0-G1 phase and promoted apoptosis in gastric cancer cells. miR-182 was a target of circNRIP1 and its deficiency reversed the effect of circNRIP1 silence on cell migration, invasion, cell cycle distribution and apoptosis in gastric cancer cells. Moreover, ROCK1 was validated as a target of miR-182 and competitively regulated by circNRIP1. Conclusion Silence of circNRIP1 inhibited progression of gastric cancer by increasing miR-182 and decreasing ROCK1, providing a novel target for the treatment of gastric cancer.

Abstract
The incidence of intervertebral disc degeneration (IDD) is increasing, especially among elderly individuals. The present study aimed to investigate the effects of the NF-κB/p53 signaling pathway on IDD and its regulatory effect on associated cytokines. In the present study, human nucleus pulposus cells were isolated from patients with thoracic-lumbar fractures and patients with IDD to observe cellular morphology and detect phosphorylated (p)-p65/p53 expression levels. The locality and expression levels of p65 in interleukin (IL)-1β-stimulated nucleus pulposus cells, with or without the addition of ammonium pyrrolidinedithiocarbamate (PDTC; a NF-κB signaling pathway-specific blocker), were measured. Furthermore, the effects of IL-1β stimulation on the protein and gene expression levels of IDD-related cytokines were determined following p53 knockdown and inhibition of the NF-κB signaling pathway. The results suggested that p-p65 and p53 expression was significantly increased in IDD cells compared with normal nucleus pulposus cells. Moreover, nucleus pulposus cells isolated from patients with IDD contained less cytoplasm compared with normal nucleus pulposus cells, and p65 expression levels were higher in the cytoplasm than the nucleus of IL-1β-stimulated PDTC-treated healthy nucleus pulposus cells. Moreover, the p53 expression levels were significantly decreased following transfection with sip53. PDTC treatment and p53 knockdown significantly decreased matrix metallopeptidase (MMP)-3, MMP-13, metallopeptidases with thrombospondin type 1 motif (ADAMTS)-4 and ADAMTS-5 expression levels, and increased aggrecan and collagen type II expression levels in IL-1β-stimulated cells. The present study indicated that activation of the NF-κB/p53 signaling pathway might be related to the occurrence of IDD; therefore, the NF-κB/p53 signaling pathway may serve as a therapeutic target for IDD.

Abstract
OBJECTIVE To investigate the role of microRNA-145-5p (miR-145-5p) in regulating the proliferation, migration, invasion and apoptosis of human endometrial carcinoma cells. METHODS Human endometrial carcinoma Ishikawa cells were transfected with miR-145-5p mimic, miR-145-5p inhibitor, or their negative controls via liposome (Lipo2000), and the changes in the expression of miR-145-5p was verified by real-time PCR. The effects of overexpression or inhibition of miR-145-5p on the proliferation, migration, invasion and apoptosis of the cells were evaluated using MTT assay, wound healing assay, Transwell assay or flow cytometry. Bioinformatic analysis was performed to predict the target genes of miR-145-5p. The mRNA and protein expression levels of the downstream target of miR-145-5p, namely dual specific phosphatase 6 (DUSP6), were detected using real-time PCR and Western blotting. RESULTS Transfection of the cells with miR-145-5p mimic significantly suppressed the proliferation of Ishikawa cells, while transfection with miR-145-5p inhibitor obvious enhanced the proliferation of the cells (P < 0.05). Over-expression of miR-145-5p significantly suppressed the migration and invasion and promoted apoptosis of the cells, and inhibition of miR-145-5p caused the reverse changes (P < 0.05). Bioinformatic analysis showed that DUSP6 was the potential target gene of miR-145-5p. Over-expression of miR-145-5p significantly lowered while inhibition of miR-145-5p significantly enhanced the expression of DUSP6 protein (P < 0.05). CONCLUSIONS Overexpression of miR-145-5p inhibits the proliferation, migration and invasion and promotes apoptosis of endometrial cancer cells possibly by negative regulation of DUSP6 expression.

JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2020; 39:113. [PMID: 32546278 PMCID: PMC7298755 DOI: 10.1186/s13046-020-01618-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/01/2020] [Accepted: 06/08/2020] [Indexed: 01/26/2023]
Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive tumors in the world. Aryl hydrocarbon receptor (AHR) has been reported to promote tumor metastasis and epithelial-mesenchymal transition (EMT) is a vital process of conferring cancer cells capabilities of migration and invasion. However, the mechanism by which modulation of AHR can inhibit tumor metastasis remains unknown. Thus, we aim to investigate the underlying mechanism regarding reversing EMT process of ESCC through modulation of AHR. METHODS We used AHR selective modulator 3,3'-diindolylmethane (DIM) to treat ESCC cell lines TE1 and KYSE150 so as to examine alterations of migration and invasion by wound healing and Transwell assay. Western blotting (WB) and qPCR were performed to detect relative genes and proteins changes regarding EMT process. Cell transfection was utilized for confirming pathways involved in DIM-induced reversal of EMT and in vivo assay was conducted for verification of the underlying mechanism. Co-IP assay was conducted for detecting protein-protein interactions. RESULTS AHR was overexpressed in ESCC and modulation of AHR by DIM could inhibit migration and invasion as well as downregulate mesenchymal cell markers β-Catenin, Vimentin and Slug and upregulate epithelial cell marker Claudin-1. Meanwhile, synergically overexpression of AHR, RhoA and ROCK1 correlated with poor clinical outcomes. DIM could inhibit COX2/PGE2 pathway by targeting AHR, and COX2 selective inhibitor Celecoxib could suppress EMT and metastasis. Results of PGE2 treatment were opposite to that of Celecoxib. Meanwhile, blockade of RhoA/ROCK1 pathway also exerted prohibitive effects on EMT and metastasis. WB results showed COX2/PGE2 pathway could be regulated by RhoA/ROCK1 pathway and DIM could inhibit RhoA/ROCK1 pathway through modulation of AHR. In vivo assay verified the results in vitro. Co-IP results showed DIM could modulate AHR to reverse EMT directly through inhibition of interaction between AHR and EGFR (epidermal growth factor receptor) so as to block RhoA/ROCK1-mediated COX2/PGE2 pathway which was connected by NF-κB. CONCLUSIONS In brief, modulation of AHR by DIM can reverse EMT process and inhibit metastasis of ESCC through repressing RhoA/ROCK1-mediated COX2/PGE2 pathway.

Abstract
Thyroid hormone receptor-interacting protein 6 (TRIP6), a member of the zyxin family of Lin-Isl-Mec (LIM) proteins, is an adaptor protein primarily expressed in epithelial cells. TRIP6 can regulate a variety of cellular responses, such as actin cytoskeletal reorganization and cell adhesion. However, to the best of our knowledge, the role of TRIP6 in osteosarcoma (Os) has not been previously reported. Therefore, the present study investigated the role of TRIP6 in the occurrence and development of Os, and the potential of utilizing TRIP6 as a therapeutic target in Os. The present results suggested that the expression levels of TRIP6 were significantly increased in Os cells and clinical tissue specimens compared with normal osteoblasts and adjacent non-tumor tissue. Moreover, the present results suggested that overexpressing TRIP6 significantly increased proliferation, migration and invasion, while inhibiting apoptosis in Os cells. However, silencing TRIP6 decreased proliferation, migration and invasion, while activating apoptosis in Os cells. The present results suggested that overexpression of TRIP6 increased NF-κB activation by decreasing the protein expression levels of inhibitor of κBα, and increasing total and phosphorylated P65 levels. The present results indicated that TRIP6 silencing decreased NF-κB activation. Collectively, the present results suggested that TRIP6 may play a role in promoting Os cell proliferation, migration and invasion, while inhibiting cell apoptosis. Furthermore, TRIP6 may be utilized as a novel prognostic biomarker and therapeutic target in Os.

Inhibition of Rho-Kinase Downregulates Th17 Cells and Ameliorates Hepatic Fibrosis by Schistosoma japonicum Infection. Cells 2019; 8:cells8101262. [PMID: 31623153 PMCID: PMC6829618 DOI: 10.3390/cells8101262] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 10/14/2019] [Accepted: 10/15/2019] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Schistosomiasis is an immunopathogenic disease in which Th17 cells play vital roles. Hepatic granuloma formation and subsequent fibrosis are its main pathologic manifestations and the leading causes of hepatic cirrhosis, and effective therapeutic interventions are lacking. In this study, we explored the effects of fasudil, a selective RhoA-Rho-associated kinase (ROCK) inhibitor, on Th17 cells and the pathogenesis of schistosomiasis. METHODS Mice were infected with Schistosoma japonicum and treated with fasudil. The worm burden, hepatic granuloma formation, and fibrosis were evaluated. The roles of fasudil on Th17, Treg, and hepatic stellate cells were analyzed. RESULTS Fasudil therapy markedly reduced the granuloma size and collagen deposit in livers from mice infected with S. japonicum. However, fasudil therapy did not affect the worm burden in infected mice. The underlying cellular and molecular mechanisms were investigated. Fasudil suppressed the activation and induced the apoptosis of CD4+ T cells. Fasudil inhibited the differentiation and effector cytokine secretion of Th17 cells, whereas it upregulated Treg cells in vitro. It also restrained the in vivo interleukin (IL)-4 and IL-17 levels in infected mice. Fasudil directly induced the apoptosis of hepatic stellate cells and downregulated the expressions of hepatic fibrogenic genes, such as collagen type I (Col-I), Col-III, and transforming growth factor-1 (TGF-β1). These effects may contribute to its anti-pathogenic roles in schistosomiasis. CONCLUSIONS Fasudil inhibits hepatic granuloma formation and fibrosis with downregulation of Th17 cells. Fasudil might serve as a novel therapeutic agent for hepatic fibrosis due to schistosome infections and perhaps other disorders.
