Activation and/or overexpression of the protein product of the ras gene family (p21ras) has been implicated in the development of various cancers, including bladder carcinoma. We have used the anti-p21ras monoclonal antibody, RAP-5, to assess the level and pattern of expression in formalin-fixed, paraffin-embedded tissue sections of both normal and malignant urothelium. All 14 random normal bladder biopsies and 67 of 68 transitional cell carcinomas of the urinary bladder were positively stained with the RAP-5 antibody. In normal urothelium, p21ras staining tended to be localized to the superficial cell layer. With increasing histological grade and/or depth of invasion of the tumour, a greater proportion of tissue sections demonstrated a staining pattern which was more uniform with respect to the different epithelial cell types. Serially diluting the primary antibody did not reveal any significant differences in the staining patterns observed. Despite the change in staining pattern with increasing grade, these results suggest that p21ras expression by itself is not a useful indicator of the malignant phenotype.
