Therefore, PEC PEC is believed to the therapeutic potential for gastric cancer and regulates tumors via pathways such as calcium, MAPK, PI3K/AKT/mTOR, and others, based on LC–MS/MS analysis, GO analysis, and reconfirmation of the expression of 6 genes in cells of AGS-xenograft tumors. The gene discussed is MTOR; the disease is gastric cancer.
