Abstract: Objective To explore the effect of silencing metastasis-associated in colon cancer 1 ( MACC1 ) gene on proliferation and invasion of cervical cancer Hela cells. Methods siRNA MACC1 and siRNA NC were transfected into cervical cancer Hela cells with liposomes. The expression of MACC1 protein and mRNA was detected by western blot and RT-PCR. Cell viability and invasion ability were measured by MTT and transwell assay, respectively. The expression of cyclin D1, cyclin E matrix metalloproteinase 2 (MMP2), MMP9 and the level of extracellular regulated protein kinases ( ERK) phosphorylation was detected by western blot. Results Compared with siRNA NC, the expression of MACC1 protein and mRNA was down-regulated, cell viability and invasion ability were reduced ( P < 0. 01 ) , cell cycle was arrested at G1 phase (P < 0. 01), the expression of cyclin D1, cyclin E, MMP2, MMP9 and p-ERK1/2 was down-regulated (P< 0. 01). Conclusions siRNA MACC1 can inhibit proliferation and invasion of cervical cancer Hela cells, which migiht be related to down-regulation of p-ERK.
