RNA-Seq of B-Cell Lines Clones, parental and resistant to Idelalisib or IMGN529

Idelalisib was the first-in-class PI3Kδ inhibitor and additional compounds are undergoing clinical investigation. To identify modalities to overcome resistance to these agents, we have developed idelalisib-resistant model derived from marginal zone lymphoma cell line (VL51). Cells were kept under idelalisib until acquisition of resistance (VL51-RER) or with no drug (parental). In this experiment we identified the modulated genes between the resistant cell line and the parental counterpart (sensitive to the drug) We invastigated the transcriptomic profiles of parental K1718 B-cell lymphoma cell lines and the same cell line made resistant to Idelalisib. in addition two B-Cells (SUDHL2 and SUDHL4) are made resistant to IMGN529 (Naratuximab emtansine) an antibody-drug conjugate (ADC) incorporating an anti-CD37 monoclonal antibody conjugated to the maytansinoid DM1 as payload.
