    4. Clear-cell renal carcinoma cell lines whose ability to proliferate in vitro and in vivo is sensitive to wild-type BAF180, but not a tumor-associated BAF180 mutant, showed that the growth suppression by BAF180 is linked to its ability to form a canonical PBAF complex containing BRG1 that dampens the HIF transcriptional signature.
