Silencing of YAP gene expression inhibits gastric cancer cell proliferation and promotes apoptosis. (A, upper panels) and (B) Ki-67 expression levels were detected by immunohistochemistry. (A, lower panels) and (C) TUNEL analysis of cell apoptotic rate. Magnification, x200. Data are presented as the mean ± standard deviation. **P<0.01 vs. CON and NC groups. CON, untransfected cells; NC, negative control vector-transfected cells; YAP-shRNA, yes-associated protein small hairpin RNA vector-transfected cells; TUNEL, terminal deoxynucleotidyl transferase dUTP nick end labeling.
