IRF4 and Miyoshi myopathy: Noteworthy, as shown in Additional file 6E, the combination of the two treatments (lenalidomide + BETi) further increased the expression of MICA, suggesting the possibility that low-dose combinations of IMiDs with BETi could display additional or synergistic activities in MM, as already shown in primary effusion lymphoma (PEL) preclinical data, where the simultaneous targeting of IKZF1-IRF4-MYC increased the cytotoxic effect as compared with either agent alone [48].
