Treatment of DLBCL cells with CDK7/9 inhibitors (CDK9-IN-2, SNS-032, and THZ1) showed that both SUDHL6 and SUDHL16 venetoclax-sensitive and -resistant DLBCL cells were killed by CDK7/9 inhibition at similar IC50 concentrations, whereas SUDHL4 parental cells were more sensitive than the BH3-mutant SUDHL4 resistant cells (Figure 5B, Supplementary Figure S3A). This evidence concerns the gene CDK9 and diffuse large B-cell lymphoma.
