Medium protein expressions of REV1 were observed in urinary bladder, breast, prostate and endometrium normal tissues, while not detected (breast cancer, endometrial carcinoma) or low (urothelial carcinoma, prostate adenocarcinoma) protein expressions of REV1 were observed in corresponding cancer tissues (Figures 7A,B,D,F). Here, REV1 is linked to urothelial carcinoma.
