Objective: To investigate the mechanism of CUL4A gene on the proliferation and invasion in gastric cancer. Methods: siRNA interference the expression of CUL4A in gastric cancer SCG-7901 cells. Using CCK-8 method to detect the proliferation of each group cells. To detect the invasion of each group cells by Transwell chambers. To detect each group cells apoptosis by Annexin V-FITC/PI method,and analysis the effects of CUL4A on cell apoptosis. Using Real time-PCR to analyze the expression of EMT related genes ...
