Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in the world, and the morbidity and mortality of HCC rate in the first few malignant tumors, seriously threatening the safety of human life. LncRNA is a hot topic in tumor research in recent years. The abnormal expression of LncRNA FBXL19-AS1 and its potential target as a tumor diagnostic marker have been confirmed in colon cancer, breast cancer and lung cancer, etc. However, the study on LncRNA FBXL19-AS1 in HCC has not been reported. Rt-qPCR was used to detect the expression of FBXL19-AS1 and miR-541-5p in HCC cell lines, and luciferase reporter gene was used to detect whether there were binding sites between LncRNA FBXL19-AS1 and miR-541-5p. Interfered with FBXL19-AS1 and overexpressed miR-541-5p were detected by cell transfection. Then CCK-8 and colony formation assay were used to detect cell viability and cell proliferation. Wound healing detected the rate of cell migration and Transwell detected the rate of cell invasion. Western blot was used to detect the expression of proteins related to cell migration and invasion. The expression of FBXL19-AS1 in HCC cell lines was significantly higher than that in normal liver cells (LO2). Moreover, FBXL19-AS1 can promote HCC cell proliferation, migration and invasion. Luciferase reporter gene confirmed the binding site between LncRNA FBXL19-AS1 and miR-541-5p. After interfering with the expression of FBXL19-AS1, miR-541-5p was significantly increased. Subsequently, overexpression of miR-541-5p can inhibit the expression of lncRNA FBXL19-AS11 and promote proliferation, migration and invasion of hepatocellular carcinoma. So we can conclude that lncRNA FBXL19-AS1 promoted the proliferation, migration and invasion of HCC cells through targeting miR-541-5p.

AbstractCircular RNAs (circRNAs), continuous loops of single-stranded RNA, regulate gene expression during the development of various cancers. However, the function of circRNAs in hepatocellular carcinoma (HCC) is rarely discussed. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to determine the mRNA levels of circ_0011385, miR-361-3p, and STC2 in 96 pairs of HCC tissues (tumor tissues and adjacent normal tissues), HCC cell lines, and L02 (human normal liver cell line) cells. The relationships between circ_0011385 expression and clinical features of HCC were evaluated. Functional experiments in vitro or in vivo were used to evaluate the biological function of circ_0011385. Bioinformatics analysis was performed to predict miRNAs and mRNAs sponged by circ_0011385. RNA immunoprecipitation (RIP) and dual-luciferase reporter gene assays were used to elucidate the interactions among circ_0011385, miR-361-3p, and STC2 (stanniocalcin 2). ChIP and dual-luciferase reporter gene assays were used to identify the upstream regulator of circ_0011385. High expression of circ_0011385 was observed in HCC tissues and cell lines and was significantly associated with tumor size, TNM stage, and prognosis. In addition, inhibition of circ_0011385 expression prevented the proliferation of HCC cells in vitro and in vivo. Circ_0011385 sponged miR-361-3p, thereby regulating the mRNA expression of STC2. In addition, the transcription of circ_0011385 was regulated by SP3. Circ_0011385 knockdown suppressed cell proliferation and tumor activity in HCC. Circ_0011385 may therefore serve as a new biomarker in the diagnosis and treatment of HCC.

Background: Gastric cancer (GC), one of the common clinical malignant tumors of the digestive system, is the fourth most commonly diagnosed cancer and the second lethal cancer worldwide, has the characteristics of high metastasis, fatality, and recurrence rate. This research was conducted to investigate the role and mechanism of miR-4295 in gastric cancer. Methods: The expression capacity of miR-4295 was determined in gastric cancer tissues and its normal tissues by qRT-PCR. PTEN expression level was detected by western blot. SGC-7901 and MGC-803 cell lines were cultured and transfected with miR-4295 or its inhibitor. The effects of miR-4295 on cell proliferation, colony formation, migration and invasion in vitro were investigated. The mutual effect between miR-4295 and PTEN in 293T cells was explored by luciferase reporter gene assays. Results: The results showed that miR-4295 expression was higher in gastric cancer tissues and cell lines, and the miR-4295 level was significantly negative associated with the tumor size and distal metastasis of gastric cancer. Notably, up-regulated miR-4295 promoted cell proliferation, migration and invasion in vitro, whereas it led to contrary effects while down-regulating miR-4295 expression. Further mechanism studies displayed that miR-4295 could directly fasten the PTEN 3’UTR and dramatically decrease the level of PTEN in vitro. Conclusion : The findings revealed that miR-4295 could promote gastric cancer cell proliferation, migration and invasion, which might be attributed to targeting PTEN. Our study suggested that miR-4295 might be a potential therapeutic target for gastric cancer.

Abstract Background Hepatocellular carcinoma (HCC) is a common type of malignant human cancer with high morbidity and poor prognosis, causing numerous deaths per year worldwide. Growing evidence has been demonstrated that long non-coding RNAs (lncRNAs) are closely associated with hepatocarcinogenesis and metastasis. However, the roles, functions, and working mechanisms of most lncRNAs in HCC remain poorly defined. Methods Real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression level of CCDC183-AS1 in HCC tissues and cell lines. Cell proliferation, migration and invasion ability were evaluated by CCK-8 and transwell assay, respectively. Animal experiments were used to explore the role of CCDC183-AS1 and miR-589-5p in vivo. Bioinformatic analysis, dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were performed to confirm the regulatory relationship between CCDC183-AS1, miR-589-5p and SKP1. Results Significantly upregulated expression of CCDC183-AS1 was observed in both HCC tissues and cell lines. HCC patients with higher expression of CCDC183-AS1 had a poorer overall survival rate. Functionally, overexpression of CCDC183-AS1 markedly promoted HCC cell proliferation, migration and invasion in vitro and tumor growth and metastasis in vivo, whereas the downregulation of CCDC183-AS1 exerted opposite effects. MiR-589-5p inhibitor counteracted the proliferation, migration and invasion inhibitory effects induced by CCDC183-AS1 silencing. Mechanistically, CCDC183-AS1 acted as a ceRNA through sponging miR-589-5p to offset its inhibitory effect on the target gene SKP1, then promoted the tumorigenesis of HCC. Conclusions CCDC183-AS1 functions as an oncogene to promote HCC progression through the CCDC183-AS1/miR-589-5p/SKP1 axis. Our study provided a novel potential therapeutic target for HCC patients.

Background/Aims: To investigate the biological roles and underlying molecular mechanisms of long non-coding RNA (lncRNA) PVT1 in Hepatocellular carcinoma (HCC). Methods: qRT-PCR was performed to measure the expression of miRNA and mRNA. Western blot was performed to measure the protein expression. CCK-8 assay was performed to determine cell proliferation. Flow cytometry was performed to detect cell apoptosis. Wounding-healing assay and Transwell assay was performed to detect cell migration and invasion. Dual luciferase reporter assay was performed to verify the target relationship. Quantichrom iron assay was performed to check uptake level of cellular iron. Results: PVT1 expression was up-regulated in HCC tissues and cell lines. Function studies revealed that PVT1 knockdown significantly suppressed cell proliferation, migration and invasion, and induced cell apoptosis in vitro. Furthermore, PVT1 could directly bind to microRNA (miR)-150 and down-regulate miR-150 expression. Hypoxia-inducible protein 2 (HIG2) was found to be one target gene of miR-150, and PVT1 knockdown could inhibit the expression of HIG2 through up-regulating miR-150 expression. In addition, the expression of miR-150 was down-regulated, while the expression of HIG2 was up-regulated in HCC tissues and cell lines. Moreover, inhibition of miR-150 could partly reverse the biological effects of PVT1 knockdown on proliferation, motility, apoptosis and iron metabolism in vitro, which might be associated with dysregulation of HIG2. In vivo results showed that PVT1 knockdown suppressed tumorigenesis and iron metabolism disorder by regulating the expression of miR-150 and HIG2. Conclusion: Taken together, the present study demonstrates that PVT1/miR-150/HIG2 axis may lead to a better understanding of HCC pathogenesis and provide potential therapeutic targets for HCC.

Background/Aims: MicroRNA-142-3p (miR-142-3p) is dysregulated in many malignancies and may function as a tumor suppressor or oncogene in tumorigenesis and tumor development. However, few studies have investigated the clinical significance and biological function of miR-142-3p in hepatocellular carcinoma (HCC). Methods: The expression levels of taurine upregulated gene 1 (TUG1), miR-142-3p, and zinc finger E-box-binding homeobox 1 (ZEB1) were evaluated in HCC tissues and cell lines by quantitative real-time PCR. MTT and colony formation assays were used to detect cell proliferation ability, transwell assays were used to assess cell migration and invasion, and luciferase reporter assays were used to examine the interaction between the long noncoding RNA TUG1 and miR-142-3p. Tumor formation was evaluated through in vivo experiments. Results: miR-142-3p was significantly downregulated in HCC tissues, but TUG1 was upregulated in HCC tissues. Knockdown of TUG1 and upregulation of miR-142-3p inhibited cell proliferation, cell migration, cell invasion, and the epithelial-mesenchymal transition (EMT). miR-142-3p was found to be a prognostic factor of HCC, and the mechanism by which TUG1 upregulated ZEB1 was via direct binding to miR-142-3p. In vivo assays showed that TUG1 knockdown suppressed cell proliferation and the EMT in nude mice. Conclusion: The results of this study suggest that the TUG1/miR-142-3p/ ZEB1 axis contributes to the formation of malignant behaviors in HCC.

The present study explored the effect of long non-coding RNA-human ovarian cancer-specific transcript 2 (LncRNA-HOST2) on cell proliferation, migration, invasion and apoptosis of human hepatocellular carcinoma (HCC) cell line SMMC-7721. HCC tissues and adjacent normal tissues from 162 HCC patients were collected. The HCC cell lines were assigned into the control group (regular culture), negative control (NC) group (transfected with siRNA) and experimental group (transfected with Lnc-HOST2 siRNA). Quantitative real-time PCR (qRT-PCR) was used to detect the expression of LncRNA-HOST2. Cell proliferation was detected by CCK-8 and colony-forming assays, cell apoptosis by flow cytometry and cell migration by Scratch test. Transwell assay was used to evaluate cell migration and invasion abilities. LncRNA-HOST2 expression in the HCC tissues increased 2–10 times than that in the adjacent normal tissues. Compared with the HL-7702 cell line, LncRNA-HOST2 expression in HepG2, SMMC-7721 and Huh7 cell lines was all up-regulated, but the SMMC-7721 cell had the highest Lnc-HOST2 expression. The LncRNA-HOST2 expression in the experimental group was down-regulated as compared with the control and NC groups. In comparison with the control and NC groups, cloned cells reduced, cell apoptosis increased, clone-forming ability weakened and inhibitory rate of colony formation increased in the experimental group. The cells migrating and penetrating into the transwell chamber were fewer in the experimental group than those in the control and NC groups. The experimental group exhibited slow wound healing and decreased cell migration area after 48 h. These findings indicate that LncRNA-HOST2 can promote cell proliferation, migration and invasion and inhibit cell apoptosis in human HCC cell line SMMC-7721.

This paper mainly studies the important role of miR-889 in the occurrence and development of hepatocellular carcinoma and the prognostic significance of miR-889 in hepatocellular carcinoma. Methods Quantitative real-time PCR analysis detected the expression levels of miR-889 in hepatocellular carcinoma tissues and cell lines. Kaplan-Meier curve and Cox regression analysis were used to explore the prognostic significance of miR-889 in hepatocellular carcinoma. The CCK-8 and Transwell assays assay were used to assess cell proliferation, migration, and invasion abilities ability. Results The expression of miR-889 in hepatocellular carcinoma tissues was significantly higher than that in adjacent tissues. Overexpression of miR-889 was significantly associated with TNM stage, hepatitis B virus infection, and cirrhosis. Patients with high miR-889 expression had shorter overall survival than those with low miR-889 expression. And functional studies in two hepatocellular carcinoma cell lines have shown that overexpression of miR-889 significantly promoted cell proliferation, migration, and invasion in vitro. Conclusions Overall, miR-889 was upregulated in hepatocellular carcinoma tissues and cell lines, and overexpression of miR-889 promoted cell proliferation, migration, and invasion in hepatocellular carcinoma cells. Based on our findings, high expression of miR-889 may promote the progression of hepatocellular carcinoma, and high expression of miR-889 is also forecasted for an unfavorable prognosis in hepatocellular carcinoma.

IntroductionThis study aimed to investigate the biological role of microRNA 93 (miR-93), a novel tumor-related miRNA, in human hepatocellular carcinoma (HCC) and elucidate the potential molecular mechanisms involved.Material and methodsQuantitative real-time polymerase chain reaction (qRT-PCR) was conducted to determine the expression of miR-93 in HCC tissues and cell lines. The log-rank test and Kaplan-Meier survival analysis were performed to evaluate the relationship between miR-93 expression and overall survival. MTT assay, colony formation assay, Transwell migration and invasion assays were carried out to exam cell proliferation, colony formation, migration and invasion, respectively. Murine xenograft models were established to the effect of miR-93 on tumor growth in vivo. TargetScan online software was applied to predict the potential target of miR-93. Luciferase reporter assays were used to validate the direct binding of miR-93 and its putative target.ResultsHere we found that miR-93 was significantly down-regulated in HCC tissues and cell lines. Patients with decreased miR-93 expression had a significantly shorter overall survival. Functional investigations demonstrated miR-93 over-expression suppressed HCC cell proliferation, weakened clonogenic ability, and slowed down cell migration and invasion; whereas miR-93 depletion facilitated HCC cell proliferation, colony formation, cell migration and invasion. MiR-93 over-expression retarded tumor growth in vivo. Luciferase reporter assay and rescue assay revealed that zinc finger protein 322 (ZNF322) was a direct target of miR-93 and mediated the inhibitory effects of miR-93 on HCC cell proliferation and motility.ConclusionsOur data may provide some evidence for miR-93/ZNF322 axis a candidate therapeutic target for HCC.
