Our observations indicate that treatment of MM cells with micromolar concentrations of a CBP/EP300-BRi (SGC-CBP30) repressed the expression of IRF4 and upregulated cell surface and mRNA expression of MICA (Fig. 8), suggesting an immunomodulatory potential associated with the selective inhibition of the CBP/EP300 bromodomain. This evidence concerns the gene CREBBP and Miyoshi myopathy.
