While BET proteins are known to similarly target MYC in multiple myeloma, a comparison of CBP/EP300 and BET bromodomain inhibition demonstrated that these modalities target the IRF4-MYC network at different nodes, with BET inhibition having no impact on IRF4 at the doses and timepoints examined (Figure 6E, Figure 3D, and Figure 4—figure supplement 1B). The gene discussed is CREBBP; the disease is plasma cell myeloma.
