STEAP1 and colonic neoplasm: The total protein expression of STEAP1 in breast cancer, colon cancer, lung adenocarcinoma, and UCEC samples was significantly higher than that in normal samples with p value less than 0.001 (Figure S1a-d) whereas primary ovarian tumor samples exhibited lower STEAP1 expression level than normal samples with p value less than 0.01 (Figure S1e).
