Fig. 6. Targeting IRF4 by inhibition of the bromodomain of CBP/EP300 re-sensitized XG1LenRes and several other resistant HMCLs to lenalidomide.

a The IMiD-resistant cell line, XG1LenRes, was analyzed by MTT assay after co-treatment with lenalidomide and the indicated doses of SGC-CBP30. The response to lenalidomide was substantially restored after SGC-CBP30 was added. b Immunoblotting assays detected the changes of IRF4, MYC, and STAT3 after treatment with either lenalidomide and SGC-CBP30 (S, 0.2 and 0.4 μM) alone or combination (day 3). c SGC-CBP30 treatment also reduced IL6 levels in the culture media of XG1LenRes at day 2 after treatment (by ELISA assay). df The IMiD-resistant HMCLs (JJN3, MM.1SLenRes, and KMS11LenRes) were analyzed by MTT assay at day 5 after co-treatment with lenalidomide (10 μm) and the indicated doses of SGC-CBP30. g Immunoblotting analysis was performed at 24 h after co-treatment of KMS11LenRes with Lenalidomide (10 μm) and SGC-CBP30 (S1: 0.5 μM and S2: 0.625 μM)
