Overexpression of TES and its inhibitory effect on the proliferation of GC cells. Three GC cell lines used in this study were MGC803, HGC27 and SGC7901. A. TES mRNA expression in GC cells 36 h after transfection. B-D. The inhibitory effect of TES overexpression on the proliferation of GC cells sorted by flow cytometry for 7 consecutive days. This experiment is a representative of three independent experiments.
