    Background. Circular RNAs (circRNAs) possess key functions in the pathogenesis of hepatocellular carcinoma (HCC). Nonetheless, the actions of individual circRNAs in HCC remain undefined. Methods. circ_0031242, miR-944, and MAD2L1 expression were quantified by qRT-PCR. Transwell assay was utilized to examine cell invasion and migration. Glucose consumption and lactate production were measured to assess the impact on glycolysis. The relationships among circ_0031242, MAD2L1, and miR944 were examined via luciferase reporter assay. Results. circ_0031242 was notably augmented in HCC. Loss of function of circ_0031242 hindered cell proliferation, invasion, migration, glycolysis, and promoted apoptosis, as well as impeding HCC tumor growth. circ_0031242 directly targeted miR-944. Inhibition of miR-944 counteracted the effects of sicirc_0031242 on HCC cells. Additionally, miR-944 was proved to directly target MAD2L1 in HCC cells. Moreover, the promotion of MAD2L1 was able to rescue the inhibition of high miR-944 expression on HCC cell progression. Meanwhile, circ_0031242 involved the post-transcriptional modulation of MAD2L1 through miR-944. Conclusion. This study suggested that circ_0031242 regulated tumor cell progression and tumor growth through the miR-944/MAD2L1 axis in HCC.

    Background. Circular RNAs (circRNAs) play vital regulatory roles in human cancers, including hepatocellular carcinoma (HCC). In this study, we aimed to explore the functions of hsa_circ_0048674 in HCC development. Methods. Quantitative real-time polymerase chain reaction (qRT-PCR) assay was used to detect hsa_circ_0048674, ubiquitin-like with PHD and RING finger domains 1 (UHRF1), microRNA-223-3p (miR223-3p) and programmed death ligand 1 (PDL1). RNase R assay and Actinomycin D assay were employed to analyze the stability of hsa_circ_0048674. Cell Counting Kit-8 (CCK-8) assay, colony formation assay and 5- ethynyl-2'- deoxyuridine (EdU) assay were conducted to assess cell proliferation. Flow cytometry analysis, transwell assay and tube formation assay were carried out for cell apoptosis, migration, invasion and angiogenesis, respectively. Western blot assay was adopted for protein levels. Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were used to analyze the relationship between miR-223-3p and hsa_circ_0048674 or PDL1. Murine xenograft model assay was conducted for the function of hsa_circ_0048674 in vivo. Immunohistochemistry (IHC) assay was used to detect Ki-67 level in tumor tissues. Enzyme linked immunosorbent assay (ELISA) kits were employed for the concentrations of inflammatory factors. Results. Hsa_circ_0048674 was highly expressed in HCC tissues and cells. Silencing of hsa_circ_0048674 repressed cell growth, migration, invasion and angiogenesis and promoted apoptosis in HCC cells in vitro and hampered tumor growth in vivo. Hsa_circ_0048674 served as an miR-223-3p sponge to alter PDL1 expression. MiR-223-3p inhibition or PDL1 overexpression restored the impacts of hsa_circ_ 0048674 silencing on HCC malignant behaviors. In addition, hsa_circ_0048674 knockdown promoted natural killer (NK) cell-mediated cytotoxicity to HCC cells. Conclusion. Hsa_circ_0048674 knockdown decelerated HCC progression through the mediation of the miR-223-3p/PDL1 axis.

    Matrine inhibits hepatocellular carcinoma cell malignancy through the circ_0013290/miR-139-5p/MMP16 pathway
    (Universidad de Murcia, Departamento de Biologia Celular e Histiologia, 2023) Chang, Xinfeng; Huang, Zhengchun; Zhang, Zhihua; Pan, Wen; Song, Chunhua
    Background. Previous studies have shown the anticancer effect of Matrine on hepatocellular carcinoma (HCC); however, the underlying mechanism is still indistinct. Methods. The expression of circular RNA_0013290 (circ_0013290), microRNA-139-5p (miR-139-5p), matrix metallopeptidase 16 (MMP16), CyclinD1 and N-cadherin was analyzed by quantitative real-time polymerase chain reaction, Western blotting or immuno-histochemistry assay. Cell viability, proliferation, apoptosis, invasion and tube formation were analyzed by cell counting kit-8, 5-Ethynyl-2’-deoxyuridine, flow cytometry analysis, transwell invasion and tube formation assays, respectively. The associations among circ_0013290, miR-139-5p and MMP16 were predicted by starbase online database, and identified by dual-luciferase reporter and RNA pull-down assays. A xenograft mouse model assay was conducted to disclose the effects of circ_0013290 and Matrine on tumor tumorigenesis in vivo. Results. Circ_0013290 and MMP16 expression were significantly upregulated, while miR-139-5p was downregulated in HCC tissues and cells compared with the matched normal liver tissues and cells. Matrine treatment inhibited HCC cell proliferation, invasion and tube formation but induced cell apoptosis, accompanied by the decrease of CyclinD1 and N-cadherin expression; however, these effects were counteracted when circ_0013290 expression was increased. MiR-139-5p depletion or MMP16 introduction relieved Matrine-induced effects in HCC cells. The regulation of circ_0013290 toward HCC cell processes involved MMP16. With respect to the mechanism, circ_0013290 acted as a miR-139-5p sponge, and miR-139-5p targeted MMP16 in HCC cells. Besides, circ_0013290 regulated MMP16 expression through miR-139-5p. Further, circ_0013290 depletion enhanced the inhibitory effects of Matrine on tumor tumorigenesis. Conclusion. Matrine inhibited HCC cell malignancy through the circ_0013290/miR-139-5p/MMP16 pathway, suggesting that Matrine is a potential therapeutic agent for HCC

    Nomogram based on CMTM6 expression and clinical characteristics to predict postoperative overall survival in patients with hepatocellular carcinoma
    (Universidad de Murcia, Departamento de Biologia Celular e Histiologia, 2024) Dai, Mengjie; Lan, Tao; Chen, Hui; Li, Xin; Zhao, Zilong; Jiang, Yingxue; Yang, Long; Wang, Songxiang
    Background. The purpose of this study was to investigate the expression of CMTM6 in HCC tissues and its prognostic value, and to try to develop a nomogram prognostic model based on CMTM6. Methods. In this retrospective study, immunohistochemical (IHC) staining was performed in 178 patients who underwent radical hepatectomy in the same surgical team. R software was used to construct the nomogram model. The Bootstrap sampling method was used for internal validation. Results. CMTM6 is significantly expressed in HCC tissues and is closely associated with decreased overall survival (OS). PVTT (HR=6.2, 95% CI: 3.06 12.6, P<0.001), CMTM6 (HR=2.30, 95% CI: 1.27 4.0, P=0.006) and MVI (HR=10.8, 95% CI: 4.19-27.6, P<0.001) were independent predictors of OS. The nomogram combined with CMTM6, PVTT and MVI was more predictive than the traditional TNM scoring system, and the prediction effects of 1-year and 3-year OS were accurate. Conclusions. The prognosis of a patient may be predicted using high levels of CMTM6 expression in HCC tissues, and the nomogram model including CMTM6 expression has the best predictive ability.
