TGFB2 and colorectal cancer: The networks for the pathways and the involved genes are presented in Fig. 7b, from which we could see they were all related to the cancer processes and might involve in the pathological processes of GC; interestingly, we also found that TGFβ2 was included in 8 pathways, i.e., pathways in cancer, proteoglycans in cancer, hepatocellular carcinoma, gastric cancer, colorectal cancer, chronic myeloid leukemia, cell cycle, and renal cell carcinoma.
