Abstract

MircroRNA functions as tumor suppressor or promoter in hepatocellular carcinoma (HCC). Researchers have found that miR-365 expression was lower in HCC tissues compared with that in adjacent normal tissues. However, its prognostic significance and anti-proliferation effect in HCC remain to be clarified. In this study, we firstly found that miR-365 expression was lower in HCC tissues compared with that in adjacent normal tissues. Then, we analyzed miR-365 expression level and its clinicopathological and prognostic significance. Finally, overexpression of miR-365 inhibits HCC cell proliferation and migration in vitro. Our findings suggest that miR-365 expression was an independent poor prognostic factor for HCC patient overall survival and suppressed tumor cell growth. Therefore, miR-365 may serve as a valuable prognostic marker and promising target for HCC.

摘要

微小RNA在肝细胞癌(HCC)中发挥着肿瘤抑制或促进作用。研究人员发现,与相邻正常组织相比,HCC组织中miR-365的表达较低。然而,其在HCC中的预后意义和抗增殖作用仍有待阐明。在本研究中,我们首先发现与相邻正常组织相比,HCC组织中miR-365的表达较低。然后,我们分析了miR-365的表达水平及其临床病理和预后意义。最后,miR-365的过表达在体外抑制HCC细胞的增殖和迁移。我们的研究结果表明,miR-365表达是HCC患者总生存的独立不良预后因素,并抑制肿瘤细胞生长。因此,miR-365可能作为HCC的一个有价值的预后标志物和有前景的治疗靶点。
