Through the one-way ANOVA analysis of 33 tumors, we found that the expression of ptpn6 in BLCA, ESCA, HNSC, KIRC, LUAD, SKCM, STAD and UCS was significantly positively correlated with different tumor stages (Fig. 2, p < 0.05). This evidence concerns the gene PTPN6 and bladder transitional cell carcinoma.
