BRD7 and posterior cortical atrophy: In addition, to evaluate the specificity of BRD2/3/4 involvement, we treated PCa-cells with the Bi7273 inhibitor that acts explicitly on BRD9, the BRD-containing subunit of the BAF (BRG-/BRM-associated factor), and its close homolog BRD7, showing excellent selectivity versus other BET family members [35].
