Effect of EZH2 inhibition on ARID1A mutant bladder cancer cell lines


ABSTRACT: ARID1A, a subunit of SWI/SNF chromatin remodeling complex. SWI/SNF complex can regulate expression of genes involved in vital biological processes such as cell cycle, DNA damage repair and development. ARID1A is known to have high mutation rate in human cancers including bladder cancer, leading to its loss of function. Publicly available whole exome sequencing data for muscle invasive and non-muscle invasive bladder cancers, show fraction of tumors with truncated ARID1A. Thus identifying therapeutic strategies for ARID1A mutant cancers is of high importance. EZH2, a histone methyltransferase is known to over-express and play pivotal role in aggressive bladder cancer. Our preliminary studies show that treatment of EZH2 inhibitor (GSK126) on ARID1A mutant bladder cancer cells significantly reduced cancer cell viability, invasion and colony formation relative to wild type ARID1A containing cells. Here, we performed microarray experiments to assess the effect of EZH2 inhibitor on global transcriptome of both ARID1A mutant and wild type bladder cancer cell line.
