Therefore, we analyzed the prognosis of TMPRSS2 in abnormally expressed cancers using the Kaplan-Meier plotter databases and GEPIA databases, and we found that increased TMPRSS2 expression was correlated with a better prognosis in KIRP, LUAD, UCEC, LIHC, and STAD (Supplementary Figures S1A–F). This evidence concerns the gene TMPRSS2 and cancer.
