BRG1 was enriched at >2500 acetylated promoters in MDA-MB-231 cells (Figure 1B); thus their functional association goes beyond proliferation and DNA repair, and comprises inter alia cellular metabolism, response to stress, and regulation of transcription from POLR2A (Figure 1C), i.e., all three mentioned aspects related to BRG1’s role in defining the potential of cancer cells to proliferate. Here, POLR2A is linked to cancer.
