Druggable host gene dependencies in primary effusion lymphoma.

ABSTRACT: Kaposi's sarcoma-associated herpesvirus (KSHV) causes primary effusion lymphoma (PEL). Here, we review what is known about human gene essentiality in PEL-derived cell lines. We provide an updated list of PEL-specific human gene dependencies, based on the improved definition of core essential genes across human cancer types. The requirements of PEL cell lines for interferon regulatory factor 4 (IRF4), basic leukine zipper ATF-like transcription factor (BATF), G1/S cyclin D2 (CCND2), CASP8 and FADD like apoptosis regulator (CFLAR), MCL1 apoptosis regulator (MCL1), and murine double minute 2 (MDM2) have been confirmed experimentally. KSHV co-opts IRF4 and BATF to drive superenhancer (SE)-mediated expression of IRF4 itself, MYC, and CCND2. IRF4 dependency of SE-mediated gene expression is shar
