Abstract

Background

Polybromo-1 (PBRM1), a targeting subunit of the SWI/SNF chromatin remodeling complex, is mutated at a rate of ~40% in clear cell Renal Cell Carcinoma (ccRCC), second only to VHL. Whether its mutation is correlated with tumor stage is controversial. As other components of the SWI/SNF complex were also reported to be mutated in ccRCC, we aim to examine the protein expression patterns of PBRM1, ARID1A, BRG1, and BRM in ccRCC, and to investigate possible association between their loss of expression and tumor stage, as well as survival. We also included a histone modifier, SETD2, which is recently discovered to be mutated in ~15% of ccRCC.
