Our data showed that PIK3CA level was positively correlated with mitotic scores in most of the cancer types, whereas the correlation between CDH1 expression and the proportion of immune cell infiltration was positive in PRAD, LGG, OV, Uveal Melanoma (UVM), THCA, LIHC, and LUAD but negative in BRCA, Testicular Germ Cell Tumors (TGCT), Thymoma (THYM), LUSC, BLCA, Head and Neck squamous cell carcinoma (HNSC), Sarcoma (SARC), Esophageal carcinoma (ESCA), PAAD, and STAD (Figure 6A–B). The gene discussed is CDH1; the disease is pancreatic adenocarcinoma.
