EP300 and Miyoshi myopathy: Our observations indicate that treatment of human MM cell lines with CBP/EP300-BRi (SGC-CBP30) (24 to 72 h) selectively upregulates cell surface and mRNA expression of MICA with no significant effects on MICB or PVR/CD155 (Fig. 8a–c), suggesting an immunomodulatory potential associated with the specific CBP/EP300 bromodomain inhibition.
