Objective To investigate the effect of RORct overexpression on human gastric cancer MGC803 cells proliferation, migration and invasion. Methods The expressions of RORct, MMP-9 and TIMP3 mRNA and protein were detected by Real-time PCR or RT-PCR and Western blot. The effect of RORct overexpression on the proliferation, cell cycle, migration and invasion of MGC803 cells were detected by MTf, flow cytometry, wound healing and Transwell assays. Results The expressions of RORa mRNA and protein were stably increased in the RORa/MGC803 cells. The proli...
