AKT1 and gastric cancer: The protein expression pattern of 5FU treatment in the present study was similar to that of EGCG treatment, which was consistent with a previous study showing that the changes caused by 5FU injection in an orthotopic xenograft of human gastric cancer cells in the gastric submucosal layer from nude mice on the protein expression of the PI3K/Akt/mTOR pathway were small [122].
