摘要
Abstract
Objective To investigate the expression of miR-145 in hepatic carcinoma, adjacent normal hepatic tissues and HepG2 cell line, and its effect on proliferation and invasion of human hepatic carcinoma. Methods RT-PCR was performed to determine the expression of miR-145 in hepatic carcinoma, adjacent normal liver tissues and human hepatocellular carcinoma HepG2 cells. Proliferation, invasion assays were conducted to examine the effects of miR-145 on HepG2 cells through up-regulating miR-\45 expression by miR-145 mimics. Results Compared to normal hepatic tissues, miR-145 expression was decreased in liver cancer specimens and HepG2 cells (P <0. 05). Proliferation assay revealed that 100 nmol/L miR-145 significantly inhibited HepG2 cell growth at 72 h. A significantly different number of invaded HepG2 cells were observed between groups treated by 100 nmol/1 miR-\45 and controls. Conclusion The expression of miR-145 is decreased in hepatic carcinoma and HepG2 cell line. Up-regulation of miR-145 expression inhibits cell growth and invasion of HepG2 cells in vitro.关键词
