Abstract

Clear cell renal cell carcinoma is characterized by the loss of chromosome 3p, which includes several tumor suppressor genes (e.g., VHL, PBRM1, SETD2, and BAP1) as well as RASSF1a, a frequently inactivated gene in many cancers. This commentary highlights work by Catalano et al., which explores the functional consequences of Ras association domain family 1, isoform A (RASSF1A) loss in kidney epithelial cells and calls for further research to investigate the impacts of 3p loss to uncover new therapeutic targets for clear cell renal cell carcinoma.
