TWIST1-EP300 Expedites Gastric Cancer Cell Resistance to Apatinib by Activating the Expression of COL1A2

Figure 7

Knockdown of TWIST1 or EP300 reduces resistance to apatinib in parental cells overexpressing COL1A2. GC parental cells transfected with oe-COL1A2 were further transfected with sh-TWIST1 or sh-EP300. (a) The mRNA expression of TWIST1, EP300, and COL1A2 in parental cells by RT-qPCR. (b) The protein expression of TWIST1, EP300, and COL1A2 in parental cells by western blot. (c) The IC50 values of parental cells by CCK-8 assay. (d) The number of colonies formed by parental MKN-45 and AGS cells treated with 1 μM apatinib. (e) Flow cytometry analysis of the proportion of apoptotic cells in parental MKN-45 and AGS cells. Data indicate of three biological replicates. Two-way ANOVA and Tukey’s multiple comparison test; (vs. ).
