qRT-PCR results showed that CDH1 expression was decreased and CDH2, VIM and ZEB1 expression were significantly increased in the TGFβ experimental group compared with the control group (Figures 7A–D), which indicated that TGFβ is an important regulator of EMT and the promotion of EMT progression in gastric cancer cells. The gene discussed is TGFB1; the disease is gastric cancer.
