MicroRNA-761 is downregulated in colorectal cancer and regulates tumor progression by targeting Rab3D.

MicroRNA-761 is downregulated in colorectal cancer and regulates tumor progression by targeting Rab3D. Exp Ther Med. 2019 Mar;17(3):1841-1846 Authors: Ren Y, Shi G, Jiang P, Meng Q Abstract The purpose of the present study was to investigate the biological role of microRNA-761 (miR-761) in colorectal cancer (CRC) and the underlying mechanisms by which miR-761 regulates CRC cell proliferation and migration. Quantitative polymerase chain reaction was performed to measure miR-761 expression in CRC tumor tissues and cell lines. It was demonstrated that miR-761 expression was dramatically reduced in CRC tumor tissues and cell lines compared with in normal tissues and cell lines. Overexpression of miR-761 significantly decreased CRC cell growth and migration. Using bioinformatics analysis and luciferase reporter assays, Rab3D was identified as a novel target of miR-761. In addition, it was demonstrated that Rab3D expression was negatively correlated with miR-761. Furthermore, overexpression of Rab3D could reverse the inhibitory effects of miR-761 on cell proliferation and migration. Collectively, the present study demonstrated that miR-761 overexpression could inhibit the proliferation and migration of CRC cell lines, partly at least, via directly targeting Rab3D.
