Combining the results of LC–MS/MS and GO analysis, PEC controlled the expression of 582 proteins in the AGS-xenografted tumor, and it was shown to be implicated in pathways such as PI3K/AKT/mTOR, HIF-1, and Wnt, as well as the cell cycle, apoptosis, and ferroptosis. The gene discussed is MTOR; the disease is neoplasm.
