{"doi":"10.1093/narcan/zcac046","title":"Targeted zinc-finger repressors to the oncogenic HBZ gene inhibit adult T-cell leukemia (ATL) proliferation","abstract":"Human T-lymphotropic virus type I (HTLV-I) infects CD4+ T-cells resulting in a latent, life-long infection in patients. Crosstalk between oncogenic viral factors results in the transformation of the host cell into an aggressive cancer, adult T-cell leukemia/lymphoma (ATL). ATL has a poor prognosis with no currently available effective treatments, urging the development of novel therapeutic strategies. Recent evidence exploring those mechanisms contributing to ATL highlights the viral anti-sense gene HTLV-I bZIP factor (HBZ) as a tumor driver and a potential therapeutic target. In this work, a series of zinc-finger protein (ZFP) repressors were designed to target within the HTLV-I promoter that drives HBZ expression at highly conserved sites covering a wide range of HTLV-I genotypes. ZFPs were identified that potently suppressed HBZ expression and resulted in a significant reduction in the proliferation and viability of a patient-derived ATL cell line with the induction of cell cycle arrest and apoptosis. These data encourage the development of this novel ZFP strategy as a targeted modality to inhibit the molecular driver of ATL, a possible next-generation therapeutic for aggressive HTLV-I associated malignancies.","journal":"NAR Cancer","year":2023,"id":354611,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":6,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.952,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":429216,"name":"Citradewi Soemardy","orcid":null,"position":1,"is_corresponding":false},{"id":451901,"name":"Roslyn M.
