To investigate the correlation between EMT and ULBP1, we successfully induced EMT in the gastric cancer cell line SGC7901 with TGF‐β1 at concentrations of 5, 10, and 20 ng/mL in the current study, and the results showed that EMT markers, including EpCAM and Vimentin, as well as ULBP1, underwent significant changes in expression dependent on TGF‐β1 dosage (Figures 4 and 5). The gene discussed is TGFB1; the disease is gastric cancer.
