EZH2 Expression is increased in BAP1-mutant renal clear cell carcinoma and is related to poor prognosis.

ABSTRACT: Aim: BAP1 is frequently mutated in clear cell renal cell carcinoma (ccRCC) with a definitive role still unclear. Methods: In silico analysis of BAP1-mutant and wild-type gene enrichment and functional annotation in TCGA-KIRC dataset was performed. Target gene was studied based on functional clustering and was knowledge-based. Validation using in-house pathological sections were performed immunohistochemically. In vitro and in vivo studies on target gene were performed. Results: The TCGA ccRCC dataset included 534 ccRCC samples. BAP1 was frequently mutated and more frequently downregulated in ccRCC compared to normal kidney tissue or benign renal tumors. In the analysis between samples with BAP1 mutation (N = 33) and pan-negative (N = 33), we found that ca
