Meanwhile, high ptpn6 expression was correlated with good prognosis in BLCA, PAAD, sarcoma (SARC), SKCM, STAD, BRCA, CESC, KIRP, LUAD, thymoma (THYM) and UCEC from GEPIA2 and Kaplan-Meier plotter database (Fig. 3A, S1-2, all P < 0.05), suggesting the complexity of the correlation between ptpn6 expression and prognosis of different tumor types. This evidence concerns the gene PTPN6 and bladder transitional cell carcinoma.
