AKT1 and gastric cancer: We analyzed clinical drug‐resistant GC samples using immunohistochemical analysis, and the results showed that p‐p85 and p‐AKT expression in drug‐resistant GC tissues were significantly increased, and no significant differences in the expression of the apoptosis‐associated and CDDP metabolism‐related proteins were observed between CDDP chemotherapy‐resistant and nonresistant GC tissues.
