CircFOXM1 promotes proliferation and metastasis of hepatocellular carcinoma via regulating miR-1179/SPAG5 axis

AbstractHepatocellular carcinoma (HCC) predominantly occurs in patients with chronic liver disease, accounting for 70–90% of all liver cancer cases. The role of circFOXM1/miR-1179/SPAG5 axis in HCC has not been reported. This study aimed to explore the regulatory mechanism of circFOXM1 in HCC proliferation and metastasis. RNA polymerase inhibitor actinomycin D and RNase R exonuclease were used to identify circFOXM1 in HCC cells. The qRT-PCR was used to detect circFOXM1 expression. Specific siRNA for circFOXM1 was designed, and the sequence of circFOXM1 was inserted in pLCDH-ciR to overexpress circFOXM. Cell proliferation was detected by CCK8 in vitro, by tumor volume and tumor weight of HCC xenograft in vivo. Cell migration was detected by transwell test. Binding status of circFOXM1 with miR-1179 was detected by luciferase reporter gene assay. Rescue experiments were applied to identify the oncogenic mechanism of circFOXM1 in HCC cells. Actinomycin D assay confirmed the cyclization of circFOXM1. RNase R treatment showed that circFOXM1 was not affected by RNase R exonuclease. CCK8 assay, tumor volume and tumor weight showed that circFOXM1 effectively promoted HCC cell proliferation. Transwell assay showed that circFOXM effectively promoted migration and invasion abilities of HCC cells. Luciferase reporter gene activity assay showed that miR-1179 had complementary binding sites with circFOXM1 and SPAG5. CircFOXM1 silencing inhibited malignant phenotypes in HCC cells were partly rescued by either miR-1179 silencing or SPAG5 overexpression. CircFOXM1 promoted HCC cell proliferation and metastasis by regulating miR-1179/SPAG5 axis.

Abstract Objective Dysregulation of KLF7 participates in the development of various cancers, but it is unclear whether there is a link between HCC and aberrant expression of KLF7. The aim of this study was to investigate the role of KLF7 in proliferation and migration of hepatocellular carcinoma (HCC) cells. Methods CCK8, colony growth, transwell, cell cycle analysis and apoptosis detection were performed to explore the effect of KLF7, VPS35 and Ccdc85c on cell function in vitro. Xenografted tumor growth was used to assess in vivo role of KLF7. Chip-qPCR and luciferase reporter assays were applied to check whether KLF7 regulated VPS35 at transcriptional manner. Co-IP assay was performed to detect the interaction between VPS35 and Ccdc85c. Immunohistochemical staining and qRT-PCR analysis were performed in human HCC sampels to study the clinical significance of KLF7, VPS35 and β-catenin. Results Firstly, KLF7 was highly expressed in human HCC samples and correlated with patients’ differentiation and metastasis status. KLF7 overexpression contributed to cell proliferation and invasion of HCC cells in vitro and in vivo. KLF7 transcriptional activation of VPS35 was necessary for HCC tumor growth and metastasis. Further, co-IP studies revealed that VPS35 could interact with Ccdc85c in HCC cells. Rescue assay confirmed that overexpression of VPS35 and knockdown of Ccdc85c abolished the VPS35-medicated promotion effect on cell proliferation and invasion. Finally, KLF7/VPS35 axis regulated Ccdc85c, which involved in activation of β-catenin signaling pathway, confirmed using β-catenin inhibitor, GK974. Functional studies suggested that downregulation of Ccdc85c partly reversed the capacity of cell proliferation and invasion in HCC cells, which was regulated by VPS35 upregulation. Lastly, there was a positive correlation among KLF7, VPS35 and active-β-catenin in human HCC patients. Conclusion We demonstrated that KLF7/VPS35 axis promoted HCC cell progression by activating Ccdc85c-medicated β-catenin pathway. Targeting this signal axis might be a potential treatment strategy for HCC.

AbstractCircular RNAs have been reported to play significant roles in regulating pathophysiological processes while also guiding clinical diagnosis and treatment of hepatocellular carcinoma (HCC). However, only a few circRNAs have been identified thus far. Herein, we investigated the role of a specific closed-loop structure of hsa_circ_101555 that was generated by back-splicing of the host gene casein kinase 1 gamma 1 (CSNK1G1) in the development and proliferation of HCC. We investigated the expression of Hsa_circ_101555 in HCC and normal tissues using bioinformatics. The expression level of hsa_circ_101555 was further detected by fluorescence in situ hybridization and qRT-PCR in ten HCC patients. Transwell, migration, WST-1 assays, and colony formation assays were used to evaluate the role of hsa_circ_101555 in HCC development and proliferation. The regulatory mechanisms of hsa_circ_101555 in miR-145-5p and CDCA3 were determined by dual luciferase reporter assay. A mouse xenograft model was also used to determine the effect of hsa_circ_101555 on HCC growth in vivo. hsa_circ_101555 showed greater stability than the linear RNA; while in vitro and in vivo results demonstrated that hsa_circ_101555 silencing significantly suppressed cell proliferation, migration, and invasion of HCC cells. Rescue experiments further demonstrated that suppression of miR-145-5p significantly attenuated the biological effects of hsa_circ_101555 knockdown in HCC cells. We also identified a putative oncogene CDCA3 as a potential miR-145-5p target. Thus, our results demonstrated that hsa_circ_101555 might function as a competing endogenous RNA of miR-145-5p to upregulate CDCA3 expression in HCC. These findings suggest that hsa_circ_101555 may be a potential therapeutic target for patients with HCC.

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.

Hepatocellular carcinoma (HCC) is a severe disease with high mortality in the world. Emerging evidence has suggested that lncRNAs play an important role in cancer progression, including HCC. This study aimed to comprehensively investigate the effect of lncRNA RHPN1 antisense RNA 1 (RHPN1-AS1) on HCC and its underlying molecular mechanism. In this study, we evaluated the expressions of lncRNA RHPN1-AS1 and miR-7-5p by qRT-RCR in both HCC tissue and HCC cells. Our findings showed that lncRNA RHPN1-AS1 was upregulated in HCC tissue and HCC cells, while miR-7-5p was downregulated. LncRNA RHPN1-AS1 expression in HCC patients was closely related to vascular invasion, tumor-node-metastasis (TNM) stage and barcelona clinic liver cancer (BCLC) stage. Furthermore, we quantified cell clone-formation ability, proliferation, migration and invasion of HCCLM3 and MHCC97 H cells using several assays (colony formation assay, 5-Ethynyl-2′-deoxyuridine (EdU) assay and transwell assay, respectively). Functional experiments confirmed that silencing lncRNA RHPN1-AS1 inhibited cell proliferation, migration and invasion in HCCLM3 and MHCC97 H cells. After that, bioinformatics analysis, dual luciferase reporter gene assay, qRT-PCR and western blot were used to investigate the molecular mechanism of lncRNA RHPN1-AS1 on HCC. Mechanistically, the rescue experiments demonstrated that miR-7-5p inhibitor reversed the inhibition effect of silencing lncRNA RHPN1-AS1 on HCCLM3 cells proliferation, migration and invasion. Moreover, silencing lncRNA RHPN1-AS1 also inhibited the activation of PI3K/AKT/mTOR pathway. Taken together our findings demonstrated that lncRNA RHPN1-AS1 could facilitate cell proliferation, migration and invasion via targeting miR-7-5p and activating PI3K/AKT/mTOR pathway in HCC.

Hepatocellular carcinoma (HCC) represents a malignant tumor predominantly arising in the setting of cirrhosis and is the third most common cause of cancer-associated death on a global scale. The heterogeneous nature of HCC and limited well-recognized biomarkers may contribute to poor patient prognosis and treatment failure. In this study, we identified expression pattern of microRNA-202-3p (miR-202-3p) in HCC and characterized its functional role as well as related mechanisms. First, we collected 50 HCC tissues and 38 normal liver tissues, and after bioinformatics prediction, the expression of miR-202-3p and KDM3A was determined in the tissues. We found lowly expressed miR-202-3p and overexpressed KDM3A in HCC tissues. Then, dual-luciferase reporter gene assay was employed to test the presence of miR-202-3p binding sites in the 3’UTR of KDM3A and chromatin immunoprecipitation (ChIP) assay to homeobox A1 (HOXA1) interaction with KDM3A and MEIS3. It has been confirmed that miR-202-3p negatively regulated KDM3A responsible for increasing the expression of HOXA1 by eliminating the histone H3 lysine 9 (H3K9)me2 in HCC cells. HOXA1 could evidently increase H3K4me1 and H3K27ac enrichment in the MEIS3 enhancer region and enhance the expression of MEIS3. Functional assays were also performed with the results showing that upregulated miR-202-3p or downregulated KDM3A retarded HCC cell viability, migration, and invasion. In addition, HepG2 cells were xenografted into nude mice, and we demonstrated that upregulated miR-202-3p reduced the growth of human HCC cells in vivo. Taken together, the present study elicits a novel miR-202-3p/KDM3A/HOXA1/MEIS3 pathway in HCC, potentiating an exquisite therapeutic target for HCC.

IntroductionEmerging evidence suggests that circular RNAs (circRNAs) play critical roles in tumorigenesis. However, the roles and molecular mechanisms of circRNA leucine-rich repeat immunoglobulin domain-containing protein 3 (circ_LRIG3) in hepatocellular carcinoma (HCC) has not been investigated.Material and methodsThe expression levels of circ_LRIG3, miR-223-3p, and mitogen-activated protein kinase kinase 6 (MAP2K6) were determined by qRT-PCR. Flow cytometry was applied to determine the cell cycle distribution and apoptosis. Cell proliferation, migration and invasion were assessed by MTT, colony formation, and transwell assays. Western blot assay was employed to measure the protein levels of the snail, E-cadherin, MAP2K6, mitogen-activated protein kinase (MAPK), phospho-MAPK (p-MAPK), extracellular signal-regulated kinases (ERKs), and phospho-ERKs (p- ERKs). The relationship between miR-223-3p and circ_LRIG3 or MAP2K6 was predicted by bioinformatics tools and verified by dual-luciferase reporter assay. A xenograft tumor model was established to confirm the functions of circ_LRIG3 in vivo.ResultsCirc_LRIG3 and MAP2K6 expression were enhanced while miR-223-3p abundance was reduced in HCC tissues and cells. Knockdown of circ_LRIG3 inhibited cell proliferation, metastasis, and increasing apoptosis. MiR-223-3p was a target of circ_LRIG3, and its downregulation reversed the inhibitory effect of circ_LRIG3 knockdown on the progression of HCC cells. Moreover, MAP2K6 could bind to miR-223-3p, and MAP2K6 upregulation also abolished the suppressive impact of circ_LRIG3 interference on progression of HCC cells. Additionally, the silence of circ_LRIG3 suppressed the activation of the MAPK/ERK pathway and tumor growth by upregulating miR-223-3p and downregulating MAP2K6.ConclusionsCirc_LRIG3 knockdown inhibited HCC progression through regulating miR-223-3p/MAP2K6 axis and inactivating MAPK/ERK pathway.

Abstract MiR-130a-3p has been certified to have low expression in several types of tumors. However, the function of miR-130a-3p in glucose metabolism and hepatocellular carcinoma progression is still elusive. Here we report that miR-130a-3p has explicitly low expression in human HCC tissues and cells and is closely related to the patient's tumor size and grade. Overexpression of miR-130a-3p significantly inhibits the glucose metabolism, proliferation and migration of HCC cells in vitro. In order to further study the effects of miR-130a-3p in the glucose metabolism of HCC cells, we found that overexpression of miR-130a-3p significantly inhibited the expression of pyruvate dehydrogenase kinase 1 (PDK1). Consistently, we confirmed that PDK1 is the target gene of miR-130a-3p through dual luciferase reporter gene assays. Cell rescue experiments showed that PDK1 inhibitors reversed the enhancement of cell proliferation, migration and glucose metabolism by miR-130a-3p inhibitor in Hep3B cells. In terms of mechanism, overexpression of miR-130a-3p targeted and inhibited the expression of PDK1, after which pyruvate dehydrogenase (PDH) is activated, thus glycolysis is inhibited, the production of lactic acid and ATP is reduced, and the ability to proliferate and migrate in HCC cells is weakened. In conclusion, our study highlights efforts to target PDK1 and miR-130a-3p as potential therapeutic strategies for the treatment of HCC.

Hepatocellular carcinoma (HCC) is the third-highest cause of cancer-related death in the world. miRNAs have a role in cell division, differentiation, and death biological processes. They are typically dysregulated in cancers, affecting tumor progression. miRNA-296-3p appears to play a crucial role in cancer control, according to new research. However, its expression and roles in HCC are unknown. This study used qRT-PCR and western blotting to detect the miRNA-296-3p and male-specific lethal 2 (MSL2) expression. In addition, cell proliferation, migration, invasion, and apoptosis were studied using CCK-8, flow cytometric analysis, colony formation assay, wound healing test, and transwell assays. The results show that miRNA-296-3p is underexpressed in HCC cell lines, particularly in Huh-7 and HepG2 cells. miRNA-296-3p overexpression lowers the ability of HCC cells to proliferate, migrate, and invade while increasing cell death. Luciferase reporter experiments revealed that the MSL2 is a direct target of miRNA-296-3p. Furthermore, overexpression of miRNA-296-3p reduced MSL2 mRNA and protein levels considerably, according to our findings. Furthermore, the rescue experiments showed that the MSL2 overexpression partially blocked the inhibition effects of miRNA-296-3p mimic on the proliferation and migration of HCC cells. The above results show that miRNA-296-3p may have a repressive effect in HCC by targeting MSL2 and could be used as a therapeutic target for HCC treatment.

Abstract Background Circular RNA (circRNA), a novel type of non-coding RNA, could interact with miRNA and protein molecules to regulate the occurrence and progression of hepatocellular carcinoma (HCC). However, little is known about the pathogenesis of circ_0004913 in HCC.Materials Through the GEO (Gene Expression Omnibus database) to find dysfunctional circRNAs in HCC, and circ_0004913 was selected as the research object. Quantitative reverse transcription PCR (qRT-PCR) was used to detect the expression level of circ_0067934 in HCC tissues and cells. CCK-8, Edu and flow cytometry assays were chosed to determine the malignant behavior of transfected HCC cells. Mechanistically, RNA immunoprecipitation and dual-luciferase reporter gene assay were performed to explore the relation between circ_0067934, miR-1290 and FOXC1 (Forkhead box C1) in HCC.Results The expression of circ_0004913 was down-regulated in HCC tissues and cell lines, while the overexpression of circ_0004913 attenuates the malignant behavior of HCC cells. Bioinformatics predicted that circ_0004913 interacts with miR-1290, which targeted FOXC1 mRNA. In fact, miR-1290 promoted the malignant behavior of HCC cells, while FOXC1 had the opposite effect. In addition, circ_0004913 overexpression enhanced FOXC1 expression by reducing miR-1290 expression, thereby inhibiting the proliferation of HCC cells.Conclusion Circ_0004913 / miR-1290 / FOXC1 regulatory axis could inhibit the progress of HCC. Our findings may provide potential new targets for the diagnosis and treatment of HCC.
