RNF20 and nonpapillary renal cell carcinoma: In a recent issue, Lee et al. (Molecular and Cellular Biology (2017) pii: MCB.00265-17) demonstrate that SREBP-1c is up-regulated in ccRCC by ring finger protein 20 (RNF20) down-regulation, leading to aberrant lipid storage and pituitary tumor transforming gene 1 (PTTG1)-dependent cell cycle progression.
