According to the KEGG analysis results and the core target protein screening analysis, the cancer cell proliferation pathway and cancer cell apoptosis pathway-related proteins of the classical pathway were selected, including PI3K, mTOR, Rap, Ras, Casp3, Casp9, EGFR, VEGF, and MAPK1 as target proteins to be docked [19,20,21]. This evidence concerns the gene PIK3CD and cancer.
