(A) Schematic representation of IKAROS and IRF4 response elements of MICA and MICB promoters. (B, C) Effect of BETi on IKZF1 and IKZF3 mRNA expression in SKO-007(J3) MM cells. Real-time PCR analysis of total mRNA obtained from SKO-007(J3) cells, untreated or treated with JQ1 (0.5 μM) or lenalidomide (5 μM) for 48 h. Data, expressed as fold change units, were normalized with GAPDH and referred to the untreated cells considered as calibrator and represent the mean of three experiments (*P
