Abstract
Ovarian cancer is the common cause of cancer-related death in women and is considered the most deadly gynecological cancer. It has been established that GATA-binding protein 6 (GATA6) is abnormally expressed in several types of malignant tumors and acts as an oncogenic protein or a tumor suppressor. However, the underlying mechanism of GATA6 in ovarian cancer progression has not been elucidated. Data in the present study revealed that GATA6 expression was negatively correlated to microRNA-10a-5p (miR-10a-5p) in ovarian cancer tissue and cells and that GATA6 is directly targeted by miR-10a-5p. Notably, upregulated miR-10a-5p dramatically inhibited ovarian cancer cell proliferation, tumorigenic ability, migration, and invasion by targeting GATA6. In vitro and in vivo experiments confirmed that miR-10a-5p-mediated downregulation of GATA6 suppressed Akt pathway activation. Overall, our findings suggest that miR-10a-5p could be a novel therapeutic target for ovarian cancer, and targeting the miR-10a-5p/GATA6/Akt axis could improve outcomes in this patient population.

Abstract
Cholangiocarcinoma is a rare tumor but a challenging cancer in terms of pathological changes, clinical manifestations and therapeutic options. Recent studies have provided evidence for participation of non-coding RNAs in the carcinogenic process of cholangiocarcinoma. We demonstrate the role of long non-coding RNAs, microRNAs and circular RNAs in the pathogenesis of cholangiocarcinoma and highlight their significant position as therapeutic targets and biomarkers for this type of cancer. We also list a number of molecular axes comprising these non-coding RNAs that represent potential targets for therapeutic options in cholangiocarcinoma, based on their significant roles in the regulation of cell proliferation, differentiation and apoptosis of these cells.

Abstract
Background Osteosarcoma is a malignant bone tumor composed of mesenchymal cells producing osteoid and immature bone. This study is aimed at developing novel potential prognostic biomarkers and constructing a miRNA-mRNA network for progression in osteosarcoma. Method GSE70367 and GSE70414 were obtained in the Gene Expression Omnibus (GEO) database. GEO software and the GEO2R calculation method were used to analyze two gene profiles. The coexpression of differentially expressed miRNAs (DEMs) and genes (DEGs) was identified and searched for in the FunRich database for pathway and ontology analysis. Cytoscape was utilized to construct the mRNA-miRNA network. Survival analysis of identified miRNAs and mRNAs was performed by utilizing the Kaplan-Meier Plotter. Besides, expression levels of DEMs and target mRNAs were verified by performing quantitative real-time PCR (qRT-PCR) and Western blot (WB). Results Six differentially expressed microRNAs (DEMs) were identified, and 8 target genes were selected after screening. By using the KM Plotter software, miRNA-124 and ARHGEF3 were obviously associated with the overall survival of patients with osteosarcoma. Furthermore, ARHGEF3 was found downregulated in osteosarcoma cells by performing qRT-PCR and WB experiments. Results also showed that downregulated ARHGEF3 may associate with invasion, metastasis, and proliferation. Conclusions By using microarray and bioinformatics analysis, DEMs were selected, and a complete miRNA-mRNA network was constructed. ARHGEF3 may act as a therapeutic and prognostic target of osteosarcoma.

Abstract
Background This study aimed to investigate the expression level of the GATA6 gene in different oral cancer cells. Methods In this study, we sub-cultured normal oral epithelial cell lines HOK, human tongue squamous cell carcinoma cell lines CAL-27 and SCC-4, and human salivary gland adenoid cystic carcinoma cell lines SACC-LM and SACC-83. Subsequently, we used reverse transcription-polymerase chain reaction RT-PCR and Western blot methods to detect the mRNA and the protein expressions of GATA6 in normal oral epithelial cells, human tongue squamous cell carcinoma cells, and human salivary gland adenoid cystic carcinoma cells. Results The results of this study showed that the mRNA expression levels of GATA6 in CAL-27, SCC-4, and SACC-LM cells were significantly increased when compared with the HOK cells. However, the mRNA expression level of GATA6 in the SACC-83 cells had no significant difference compared with the HOK cells. The protein expression levels of GATA6 in the SCC-4 and SACC-LM cells were, however, significantly increased whereas the protein expression levels of GATA6 in the CAL-27 and SACC-83 cells had no significant difference when compared with the HOK cells. Conclusion The GATA6 gene may be related to the occurrence and progression of certain oral cancers.

Abstract
Cholangiocarcinoma (CCA) is a malignant tumour with high recurrence and mortality rates and poor prognosis. However, the pathogenic mechanism remains unclear. In the present study, we aimed to investigate the roles and regulatory mechanism of SNHG16 in the occurrence and development of CCA. Gene Expression Profiling Interactive Analysis (GEPIA) was used to predict the expressions of SNHG16 and GATA6 in CCA samples from TCGA database. The levels of SNHG16, miR-146a-5p and GATA6 were evaluated using qRT-PCR. CCK-8 and flow cytometry assays were conducted to evaluate cell proliferation and apoptosis, respectively. Western blotting was applied to analyse the protein levels of GATA6 and apoptosis-related proteins. SNHG16 was significantly elevated in CCA tissues from TCGA database and CCA cell lines. Moreover, downregulation of SNHG16 restricted cell proliferation and increased apoptotic rate of RBE and HuCCT1 cells. miR-146a-5p, a downstream target of SNHG16, was shown to be an intermediate mediator of GATA6 expression regulated by SNHG16. In addition, either the miR-146a-5p inhibitor or overexpression of GATA6 obviously impaired the regulatory effects of SNHG16 downregulation in RBE and HuCCT1 cells. These data demonstrated that SNHG16 promoted cell proliferation and repressed apoptosis by regulating the miR-146a-5p/GATA6 axis, which provides some helpful insights for the diagnosis and treatment of CCA.

[PMID: 33833529 PMCID: PMC8020141 DOI: 10.2147/ott.s290567] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Accepted: 03/14/2021] [Indexed: 12/14/2022] Open
Abstract
Background miR-944 belongs to the MicroRNAs family, as shown in our previous study, and is essential in the colorectal cancer (CRC) progression. It is negatively associated with invasion depth and lymph node status. Epithelial-mesenchymal transition (EMT) is essential in tumor invasion and metastasis. However, the relationship between miR-944 and EMT in CRC is unknown and should be further investigated. Methods Epithelial–mesenchymal transition (EMT) progression in CRC cell lines was detected with Cell morphology and Western blotting. CRC cell migration and invasion were examined using Transwell assays. Transcriptome and clinical data were obtained from The Cancer Genome Atlas (TCGA) database. The potential pathway of miR-944 and GATA6 were predicted using KEGG analysis. Colocalization was validated using immunofluorescence and Immunohistochemistry. Nuclear and Cytoplasmic Protein Extraction assays were conducted to determine the effects of miR-944 on Wnt/β-catenin signaling. Results We found that miR‑944 influences EGF-induced EMT malignant phenotype in vitro. KEGG analyses showed that miR-944 and GATA6 are associated with EMT related pathways, wnt signaling pathways. On the other hand, Western Blot analyses showed that miR-944 can regulate EMT and wnt-β-catenin pathway-related protein, including β-catenin, ZEB1, snail1 via GATA6 regulation. miR-944 also abrogates E-ca after EGF induction. Immunohistochemistry (IHC) and Immunofluorescence (IF) co-expression showed that GATA6 expression is positively associated with β-catenin and ZEB1. GATA6 silencing can reverse EMT malignant phenotype and alterations of related protein induced by miR-944. Quantitative polymerase chain reaction analysis results showed that miR-944 is negatively associated with the UICC stage (P= 0.02), lymph nodes (p=0.04), and liver metastasis (p=0.03). Moreover, patients with high miR-944 expression have better survival (p=0.045). We finally combined miR-944 and GATA6 and found that miR-944/GATA6 ratio could be a novel prognostic biomarker in the TCGA dataset and it is an independent risk prognosis factor (p=0.045). Conclusion Our results suggest that miR-944 suppresses the aggressive biological processes by directly repressing GATA6 expression and could be a potential candidate for therapeutic applications in CRC.

Abstract
MicroRNA-124 (miR-124) is a copious miRNA in the brain, but it is expressed in a wide range of human/animal tissues participating in the pathogenesis of several disorders. Based on its important function in the development of the nervous system, abnormal expression of miR-124 has been detected in nervous system diseases including Alzheimer's disease, Parkinson's disease, Hypoxic-Ischemic Encephalopathy, Huntington's disease, and ischemic stroke. In addition to these conditions, miR-124 contributes to the pathogenesis of cardiovascular disorders, hypertension, and atherosclerosis. Besides, it has been shown to be down-regulated in a wide range of human cancers such as colorectal cancer, breast cancer, gastric cancer, glioma, pancreatic cancer, and other types of cancer. Yet, few studies have reported upregulation of miR-124 in some cancer types. In the current study, we describe the role of miR-124 in these malignant and non-malignant conditions.

GATA6 promotes epithelial-mesenchymal transition and metastasis through MUC1/β-catenin pathway in cholangiocarcinoma. Cell Death Dis 2020; 11:860.

Abstract
GATA6 acts as an oncogene or tumour suppressor in different cancers. Previously, we found that aberrant expression of GATA6 promoted metastasis in cholangiocarcinoma (CCA). However, the mechanism by which GATA6 promotes metastasis in CCA is unclear. In the present study, we aimed to investigate the role of GATA6 in CCA cell epithelial–mesenchymal transition (EMT). Our results showed that GATA6 expression was positively associated with N-cadherin and vimentin expression but negatively associated with E-cadherin expression in 91 CCA samples. GATA6 promoted EMT and metastasis in CCA cells in vitro and in vivo based on knockdown and overexpression analyses. ChIP-sequencing data revealed that MUC1 is a novel downstream target of GATA6. GATA6 upregulated MUC1 expression through binding to both the 1584 and 1456 GATA-motifs in the promoter region and enhancing its transcription by luciferase reporter assays and point-mutant assays. MUC1 expression was positively associated with N-cadherin and vimentin expression but negatively associated with E-cadherin expression in 91 CCA samples. In addition, MUC1 promoted EMT in CCA cells based on knockdown and overexpression analyses. Moreover, MUC1 knockdown significantly abrogated the GATA6-induced EMT in CCA cells, indicating that MUC1 promoted EMT through upregulating MUC1 in CCA cells. β-Catenin is a putative transcriptional coactivator that regulates EMT in cancers. Our data showed that MUC1 expression was positively associated with nuclear β-catenin expression in 91 CCA samples. MUC1 upregulated nuclear β-catenin expression in CCA cells. Moreover, MUC1 bound to β-catenin in CCA cells based on protein immunoprecipitation analyses. MUC1 knockdown significantly decreased the binding of MUC1 to β-catenin, and thereby decreased nuclear β-catenin protein levels in CCA cells, indicating that MUC1 bound to β-catenin and increased its nuclear expression in CCA cells. Together, our results show that GATA6 promotes EMT through MUC1/β-catenin pathway in CCA, indicating potential implications for anti-metastatic therapy.

miR-124 Intensified Oxaliplatin-Based Chemotherapy by Targeting CAPN2 in Colorectal Cancer. MOLECULAR THERAPY-ONCOLYTICS 2020; 17:320-331.

Abstract
Our previous study demonstrated that miR-124 was downregulated in colorectal cancer (CRC) compared with normal mucosa, and the downregulated expression of miR-124 was an independent prognostic factor in CRC patients. However, the function of miR-124 in CRC patients treated with chemotherapy is currently unclear. The aim of this study was to determine the miR-124 expression and its regulative role in oxaliplatin (L-OHP)-based chemotherapy of CRC patients. We observed that low miR-124 expression was correlated with worse overall survival (OS) in the 220 patients who received postoperative chemotherapy of 5-fluorouracil [5-FU]+leucovorin+L-OHP (FOLFOX) or capecitabine+L-OHP (XELOX). miR-124 overexpression promoted L-OHP-induced, but not 5-FU-induced, cytotoxicity and apoptosis in HT29 and SW480 cells. CAPN2 was a direct target of miR-124, and its protein expression was reduced by forced expression of miR-124. miR-124 inhibited tumorigenesis and promoted OS of mice bearing xenograft tumors, especially upon L-OHP treatment. miR-124 also promoted L-OHP-induced apoptosis and restrained CAPN2 protein expression in xenograft tumors. Our results suggest that miR-124 could be considered as both a predictor of L-OHP-based chemotherapy for personalized treatment and a therapeutic target for CRC.

Abstract
Background: Rheumatoid arthritis (RA) is a systematic autoimmune disease which may lead to joint dysfunction and disability. Aberrant migration and invasion of fibroblast-like synoviocytes (FLSs) is one of the most predominant etiopathogenesis of RA. Quercetin is a bioflavonoid which is implicated in the development of RA, yet its role in regulating the migration and invasion of FLSs is still elusive. The aim of this study is to investigate the impact of quercetin treatment on migration and invasion of FLSs and the underlying mechanism.Methods: Capacity of migration and invasion of FLSs were assessed using transwell assay. Immunofluorescence assay was used to determine the expression of F-actin. The RNA levels of miR-146a and GATA transcription factor 6 (GATA6) were measured using quantitative real-time PCR. Western blot was used to examine the protein level of GATA6. The correlation between miR-146a and GATA6 was validated using luciferase reporter assay.Results: Transwell assay revealed that the migration and invasion of FLSs were significantly inhibited after quercetin treatment, which was also proved by decreased expression of F-actin. The RNA level of miR-146a was decreased in RA tissues and was negatively related to the expression of GATA transcription factor 6 (GATA6). Quercetin treatment elevated the RNA level of miR-146a, but suppressed the expression of GATA6 in FLSs. Further luciferase reporter assay validated that GATA6 is a downstream target of miR-146a. Besides, miR-146a inhibited the migration and invasion of FLSs, and further GATA6 over-expression abrogated the miR-146a-induced inhibition. In addition, specific anti-miR-146a inhibitor abolished quercetin-mediated suppression of migration and invasion of FLSs.Conclusion: Our study suggested that quercetin suppresses the migration and invasion of FLSs via regulating the miR-146a/GATA6 axis.

Abstract
Recent studies have indicated that ANXA7 promotes progression and metastasis of hepatocellular carcinoma (HCC). In this study we found a significant negative correlation between the levels of miR-124-3p and ANXA7 protein in HCC. Level of miR-124-3p in tumor tissues was negatively correlated, while ANXA7 protein was positively correlated, with TNM stage and tumor metastasis. Furthermore, we confirmed ANXA7 was a target gene of miR-124-3p by a dual luciferase reporter assay. In vitro, up-regulation of miR-124-3p promotes apoptosis and inhibits migration and invasion of Hca-F. Bcl-2 correlates X protein (Bax) protein level was up-regulated, while ANXA7, B-cell lymphoma-2 (Bcl-2), Matrix metalloproteinase (MMP-9) and C-X-C motif chemokine 12 (CXCL12) protein levels were suppressed relative to miR-124-3p over-expression. In vivo, up-regulation of miR-124-3p suppresses lymph node metastasis (LNM) and tumorigenicity of Hca-F cells. The expression of ANXA7, MMP-9, and CXCL12 protein in transplanted tumors was suppressed relative to miR-124-3p overexpression. In addition, we found the levels of Bcl-2, MMP-9, and CXCL12 in Hca-F cells decreased significantly after transfection of shRNA-Anxa7 in vitro. In conclusion, our study revealed miR-124-3p inhibits tumor growth, invasion, and lymphatic metastasis in HCC by down-regulation of ANXA7 gene, thereby reducing the expression of Bcl-2, MMP-9, and CXCL12.

Abstract
Cholangiocarcinoma (CCA) is devastating for its delayed presence, difficulty in diagnosis, and high mortality. Other studies have supported the important role of microRNAs (miRNAs) in the pathogenesis of CCA, and the role of miR-194 was investigated in several human cancers, though, the molecular mechanism of miR-194 in CCA stem cells remains largely unknown. We aimed to identify the functional significance of miR-194 in CCA. The microarray-based analysis was applied to detect the epithelial cell transforming sequence 2 (ECT2) expression and predict the miRNA-regulated ECT2, followed by the identification of relationship between ECT2 and obtained miRNA by dual-luciferase reporter gene assay. The effects of depletion or ectopic expression of miR-194 on Rho pathway and the biological characteristics of CCA were assessed by reverse transcription quantitative polymerase chain reaction, immunoblotting, 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide, scratch test, Transwell, and flow cytometry. Lastly, tumor growth was assessed by xenograft tumor in nude mice. ECT2 was highly expressed while miR-194 was poorly expressed in CCA stem cells, and the targeting relation between ECT2 and miR-194 was proved. More important, the elevated expression of miR-194 or ECT2 silencing inhibited the Rho pathway, and further promoted the apoptosis and suppressed the stem cell proliferation, migration, and invasion of CCA in vitro. miR-194 inhibited the tumor growth in vivo. In a word, miR-194 inhibits ECT2 and blocks the activation of Rho signaling pathway, thus promoting apoptosis, inhibiting proliferation and migration of CCA stem cells, and suppressing tumor growth. The mechanism can be regarded as a target for treating CCA.

Upregulated miR-27a-3p Indicates a Poor Prognosis in Pancreatic Carcinoma Patients and Promotes the Angiogenesis and Migration by Epigenetic Silencing of GATA6 and Activating VEGFA/VEGFR2 Signaling Pathway. Onco Targets Ther 2019; 12:11241-11254. [PMID: 31908490 PMCID: PMC6927607 DOI: 10.2147/ott.s220621] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Accepted: 11/16/2019] [Indexed: 01/03/2023] Open
Abstract
Background Abnormal miR-27a-3p expression has been frequently reported in several types of human cancer and contributes to tumor progression. However, the role and potential molecular mechanism of miR-27a-3p in the progression of pancreatic carcinoma have not been clarified. Materials and methods The expression of miR-27a-3p and GATA binding protein 6 (GATA6) in pancreatic carcinoma tissues and cell lines was evaluated by quantitative real-time PCR and Western blotting analysis. The relationship between clinical pathologic features and miR-27a-3p expression was analyzed with Chi-square test. The regulatory mechanism of miR-27a-3p on GATA6 was confirmed by luciferase reporter assay and bioinformatics analysis. The effects of miR-27a-3p by targeting GATA6 on cell angiogenesis and migration were assessed by capillary tube formation and wound healing assays. Results MiR-27a-3p expression was significantly upregulated in pancreatic carcinoma tissues and cell lines. Highly expressed miR-27a-3p was closely related to more lymph node metastasis, present peritoneal metastasis, and poor prognosis in patients with pancreatic carcinoma. MiR-27a-3p promoted migration and angiogenesis of pancreatic carcinoma cells by activating vascular endothelial growth factor A (VEGFA) and vascular endothelial growth factor receptor 2 (VEGFR2) expression. A significantly negative correlation between GATA6 mRNA and miR-27a-3 expression was found in pancreatic carcinoma samples. Modulation of miR-27a-3p could alter GATA6 expression in pancreatic carcinoma cells. GATA6 was identified as a functional target gene of miR-27a-3p, and GATA6 knockdown partially reversed the effects of miR-27a-3p siliencing on the migration and angiogenesis of pancreatic carcinoma cells by regulation of VEGFA/VEGFR2 pathway. Conclusion Upregulated miR-27a-3p indicates a poor prognosis in pancreatic carcinoma patients and promotes the angiogenesis and migration by epigenetic silencing of GATA6 and activating VEGFA/VEGFR2 signaling pathway, and indicating miR-27a-3p may be a promising therapeutic target for pancreatic carcinoma treatment.

Abstract
Background miRNAs are small noncoding RNAs that function as posttranscriptional regulators during development and disease. Aberrant expression of miRNAs has been associated with various types of malignant tumors. Decreased levels of miR-124 have been observed in human cancers. RACK1 is a scaffold protein that acts as an oncogene in various human cancers. The association between miR-124 and RACK1 in melanoma has not been characterized. Materials and methods Real-time quantitative PCR was used to analyze RACK1 and miR-124 expression in melanoma tissue and cell lines. Dual-Luciferase reporter assay was performed to evaluate the effect of miR-124 inhibition on RACK1 expression. The effects of miR-124 on RACK1 in melanoma cell lines were evaluated using Western blot analysis and immunocytochemical staining. Wound-healing, transwell, and MTT assays, and annexin V-fluorescein isothiocyanate/propidium iodide followed by flow cytometry were used to evaluate the effects of miR-124 on RACK1-mediated proliferation, migration, invasion, and apoptosis of melanoma cells. Results The expression of miR-124 in melanoma tissue was lower than that in normal skin tissue, and the expression of RACK1 was higher in melanoma tissue than that in normal skin tissue. Analysis using Dual-Luciferase reporter assay showed that RACK1 was a direct target of miR-124. Western blot and immunocytochemical staining showed that the expression of RACK1 was significantly inhibited by miR-124 in both A375 and A875 melanoma cells. Furthermore, the results of functional experiments showed that degradation of RACK1 by miR-124 inhibited proliferation, migration, and invasion of melanoma cells, and promoted melanoma cell apoptosis. Conclusion The results suggested that miR-124 affected melanoma cells by directly targeting RACK1. miR-124 and RACK1 may be biomarkers for clinical diagnosis, and prognostic factors of human melanoma. Furthermore, miR-124 and RACK1 may be targets for the treatment of melanoma.

Abstract
Cancer is a common type of non-communicable disease, and its morbidity and mortality are rapidly increasing. It is expected to become the largest obstacle to the promotion of global human health in the future. Some transcription factors that play important regulatory roles in embryogenesis and subsequent tissue maintenance can be selectively amplified during tumorigenesis. Due to its high expression in the embryonic endoderm and mesoderm, GATA6 plays a crucial role in the normal development of early human heart, lung, digestive system, adrenal glands, breasts, ovaries, retina, skin, and nervous system. Up to now, overexpression of the GATA6 gene has been shown to play an important role in several cancers, including lung cancer, digestive system tumors, breast cancer, and ovarian cancer. However, the human body is a complex organism, which causes the transcription factor GATA6 to have multiple roles in cancer. In this review, we summarize the multiple roles of transcription factor GATA6 in various cancers and its regulatory mechanisms. The aim is to better understand the relationship between GATA6 gene expression and cancer development and to provide new insights for exploring potential therapeutic targets.

Abstract
MicroRNAs (miRNAs) are noncoding single‐stranded RNAs, approximately 20‐24 nucleotides in length, known as powerful posttranscriptional regulators. miRNAs play important regulatory roles in cellular processes by changing messenger RNA expression and are widely involved in human diseases, including tumors. It has been reported in the literature that miRNAs have a precise role in cell proliferation, programmed cell death, differentiation, and expression of coding genes. MicroRNA‐124 (miR‐124) has reduced exparession in various human neoplasms and is believed to be related to the occurrence, development, and prognosis of malignant tumors. In our review, we focus on the specific molecular functions of miR‐124 and the downstream gene targets in major cancers, which provide preclinical evidence for the treatment of human cancer. Although some obstacles exist, miR‐124 is still attracting intensive research focus as a promising and effective anticancer weapon.

The p53/miRNAs/Ccna2 pathway serves as a novel regulator of cellular senescence: Complement of the canonical p53/p21 pathway. Aging Cell 2019; 18:e12918.

Abstract
Aging is a multifactorial process characterized by the progressive deterioration of physiological functions. Among the multiple molecular mechanisms, microRNAs (miRNAs) have increasingly been implicated in the regulation of Aging process. However, the contribution of miRNAs to physiological Aging and the underlying mechanisms remain elusive. We herein performed high-throughput analysis using miRNA and mRNA microarray in the physiological Aging mouse, attempted to deepen into the understanding of the effects of miRNAs on Aging process at the "network" level. The data showed that various p53 responsive miRNAs, including miR-124, miR-34a and miR-29a/b/c, were up-regulated in Aging mouse compared with that in Young mouse. Further investigation unraveled that similar as miR-34a and miR-29, miR-124 significantly promoted cellular senescence. As expected, mRNA microarray and gene co-expression network analysis unveiled that the most down-regulated mRNAs were enriched in the regulatory pathways of cell proliferation. Fascinatingly, among these down-regulated mRNAs, Ccna2 stood out as a common target of several p53 responsive miRNAs (miR-124 and miR-29), which functioned as the antagonist of p21 in cell cycle regulation. Silencing of Ccna2 remarkably triggered the cellular senescence, while Ccna2 overexpression delayed cellular senescence and significantly reversed the senescence-induction effect of miR-124 and miR-29. Moreover, these p53 responsive miRNAs were significantly up-regulated during the senescence process of p21-deficient cells; overexpression of p53 responsive miRNAs or knockdown of Ccna2 evidently accelerated the cellular senescence in the absence of p21. Taken together, our data suggested that the p53/miRNAs/Ccna2 pathway might serve as a novel senescence modulator independent of p53/p21 pathway.

Abstract
MicroRNAs (miRNAs) have been proven to regulate gene expression at the protein translation level. miRNA abnormal expression has been associated with the development of lung cancer. In the present study, we aimed to investigate the mechanism of miR-196 in non-small cell lung cancer (NSCLC). The miR-196b and GATA-6 (GATA6) expression levels were examined in NSCLC by RT-qPCR and western blot analysis. Transwell assay was used to assess cell migration and invasion. Moreover, the specific target of miR-196b in NSCLC was verified by the luciferase reporter assay. The expression of miR-196b was higher in both NSCLC tissues and cells than the normal levels. Specifically, the miR-196b mimic group in NSCLC cells markedly promoted cell migration and invasion, while the miR-196b inhibitor group exhibited the opposite effect. Furthermore, GATA6 was verified as a specific target of miR-196b in NSCLC cells and GATA6 could attenuate the migratory and invasive ability of NSCLC cells regulated by miR-196b. In addition, the relationship between GATA6 and miR-196b expression was negatively correlated in NSCLC tissues. Thus, miR-196b enhanced NSCLC cell migration and invasion via the downregulation of GATA6, indicating its potential application in NSCLC diagnosis and therapy.

Abstract
The aim of the present study was to investigate the expression and function of microRNA (miR)-371-5p in nasopharyngeal carcinoma (NPC). The levels of miR-371-5p were analyzed in nasopharyngeal epithelium tissues, NPC tissues, human NPC cell lines and NP69 cells using reverse transcription-quantitative polymerase chain reaction analysis. The association between the level of miR-371-5p and clinicopathological variables was also investigated. Cell proliferation was determined using an MTT assay, and the activities of cell metastasis were determined using wound healing and Transwell migration assays. To assess whether miR-371-5p can combine with the targeting sequence of B-cell lymphoma 2 (BCL2) mRNA or not, a luciferase activity assay was performed. An animal experiment was used to examine the effect of miR-371-5p on the development of NPC. The results revealed that the expression of miR-371-5p was reduced in NPC samples and NPC cells. The level of miR-371-5p was associated with clinical stage and distant metastasis in patients with NPC, and was inversely associated with the protein level of BCL-2 in NPC tissues. The upregulation of miR-371-5p reduced cell growth, migration and invasion, and inhibited carcinoma growth through targeting BCL2 mRNA. Taken together, the regulation of miR-371-5p was shown to offer potential as a novel treatment approach for NPC.

Abstract
AIM We sought to determine the function of miR-181a/GATA6 pathway in the progression of laryngeal squamous cell carcinoma (LSCC). MATERIALS & METHODS The expression of miR-181a and GATA6 were detected using quantitative real-time-PCR and western blotting in 127 LSCC samples and 32 corresponding control mucosa tissues. Cell death, migration and apoptosis were measured in Hep-2 cells using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT), Transwell migration assay and apoptosis assay, respectively. The prognosis was determined by the follow-up, univariate analysis and multivariate analysis. RESULTS We observed decreased miR-181a levels and increased GATA6 expression in LSCC samples compared with control mucosa tissues. Transfection of miR-181a decreased GATA6 expression, suppressed migration and promoted apoptosis in Hep-2 cells. Furthermore, silencing GATA6 suppressed cell migration and promoted apoptosis in Hep-2 cells. Notably, patients with high miR-181a levels had a longer life span. CONCLUSION MiR-181a inhibits LSCC progression via suppressing GATA6 expression. MiR-181a is an independent prognostic factor in LSCC patients.

Wu YF, Li ZR, Cheng ZQ, Yin XM, Wu JS. Decrease of miR-622 expression promoted the proliferation, migration and invasion of cholangiocarcinoma cells by targeting regulation of c-Myc. Biomed Pharmacother 2017; 96:7-13. [PMID: 28961507 DOI: 10.1016/j.biopha.2017.09.043] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2017] [Revised: 09/04/2017] [Accepted: 09/10/2017] [Indexed: 02/07/2023] Open
Abstract
OBJECTIVE To explore the mechanism of miR-622 in regulating the proliferation, migration and invasion of cholangiocarcinoma (CCA) cells. MATERIALS AND METHODS Quantitative real-time PCR was conducted to measure the expression of miR-622 and c-Myc in CCA tissues and cell lines. Protein level of c-Myc was measured by Western blot. The effect of miR-622 on cell proliferation, migration and invasion was analyzed by MTT assay and Transwell chamber migration assay. Luciferase reporter assay was performed to measure the effect of miR-622 on c-Myc. RESULTS miR-622 expression was downregulated in both CCA tissues and cell lines, while c-Myc expression was uregulated. Overexpression of miR-622 in CCA cells was statistically correlated with a decrease of cell proliferation, migration and invasion, while inhibition of miR-622 made an inverse result. We also proved c-Myc was identified as a target gene of miR-622 in CCA. Moreover, we found overexpression of c-Myc can strengthen the effects of miR-622 on the proliferation, migration and invasion of CCA cells. CONCLUSION Decrease of miR-622 promotes the proliferation, migration and invasion of CCA cells by directly targeting c-Myc.
