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 (<em>IRF4</em>), basic leukine zipper ATF-like transcription factor (<em>BATF</em>), G1/S cyclin D2 (<em>CCND2</em>), CASP8 and FADD like apoptosis regulator <em>(CFLAR)</em>, MCL1 apoptosis regulator (<em>MCL1)</em>, and murine double minute 2 (<em>MDM2</em>) have been confirmed experimentally. KSHV co-opts IRF4 and BATF to drive superenhancer (SE)-mediated expression of <em>IRF4</em> itself, <em>MYC</em>, and <em>CCND2</em>. IRF4 dependency of SE-mediated gene expression is shared with Epstein–Barr virus-transformed lymphoblastoid cell lines (LCLs) and human T-cell leukemia virus type 1-transformed adult T-cell leukemia/lymphoma (ATLL) cell lines, as well as several B-cell lymphomas of nonviral etiology. LCLs and ATLL cell lines similarly share dependencies on <em>CCND2</em> and <em>CFLAR</em> with PEL, but also have distinct gene dependencies. Genetic dependencies could be exploited for therapeutic intervention in PEL and other cancers.</p></div>","PeriodicalId":11082,"journal":{"name":"Current opinion in virology","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9682098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
