While identification of cytogenetic lesions improved risk stratification, prognostication remains inadequate with 30% of standard-risk patients experiencing relapse within 5 years. To deeply characterize pAML heterogeneity and identify poor outcome-associated blast cell profiles, we performed an analysis on 708,285 cells from 164 bone marrow biopsies of 95 patients and 11 healthy controls. The longitudinal analysis on cell abundances at the time of disease diagnosis, end of induction, and relapse identified treatment resistant stem-like blast cells specific to RUNX1::RUNX1T1, FLT3-ITD, and CBFB::MYH11 patients that are associated with poor outcomes. Treatment resistant blast cells from RUNX1::RUNX1T1 were found to associate with T cell exhaustion, while those from FLT-ITD utilized enriched antioxidant metabolism to persist through treatment. Interestingly, the analysis also identified novel mast cell-like pAML associated with treatment resistance and poor outcomes. Deconvolution of ex vivo treatment data and subsequent in vitro validation identified bortezomib (RUNX1), ponatinib, and venetoclax (FLT3) as specifically potent against treatment resistant blasts from the respective cytogenetic groups.

Therefore, it is essential to elucidate the mechanisms of resistance and develop novel treatment strategies. Histone deacetylases (HDACs) are often dysregulated in hematological malignancies, and many HDAC inhibitors have shown potent antitumor activities. In this study, we found that HDAC8 was highly expressed in Ph<sup>+</sup> B-ALL patient samples upon TKI treatment. HDAC8 inhibition significantly increased TKI-mediated elimination of leukemia cells and decreased their ability to initiate leukemia. Using two mouse models, we demonstrated that TKIs in combination with targeting HDAC8 effectively inhibited leukemia progression and reduced the frequencies of stem cells. Mechanistically, HDAC8 deacetylated hypoxia inducible factor-1α (HIF-1α) at lysine 19/21, leading to a reduction in PHD2-mediated hydroxylation and subsequent pVHL-mediated ubiquitination, which slowed the degradation of HIF-1α. HIF-1α inhibition induced apoptosis and decreased the initiating capacity of leukemia cells. Importantly, in a Ph<sup>+</sup> B-ALL patient–derived xenograft model, targeting HDAC8 or HIF-1α in combination with TKIs significantly inhibited leukemia progression.

Precision medicine approaches for MDS-<i>SF3B1</i> remain challenging due to both the complexity of the mis-splicing landscape and its evaluation in disease-accurate models. To uncover novel RNA mis-splicing events, isogenic <i>SF3B1</i><sup>K700E</sup> and <i>SF3B1</i><sup>WT</sup> iPSC lines from an MDS-<i>SF3B1</i> patient were differentiated into hematopoietic cells and analyzed via unsupervised splicing event profiling using full-length RNA sequencing. This identified <i>SF3B1</i><sup>K700E</sup>-specific mis-splicing of ubiquitin-like modifier activating enzyme 1 (<i>UBA1</i>), which encodes a key E1 protein at the apex of the ubiquitination cascade. <i>UBA1</i> mis-splicing (<i>UBA1</i><sup>ms</sup>) introduced protein instability and decreased total UBA1 levels, rendering mutated cells susceptible to the small-molecule UBA1 inhibitor TAK-243. Analysis of CD34<sup>+</sup> RNA sequencing data from an MDS patient cohort confirmed unique and ubiquitous <i>UBA1</i><sup>ms</sup> in MDS-<i>SF3B1</i> patients, absent in other splicing factor-mutated MDS cases or healthy controls. TAK-243 selectively targeted MDS-<i>SF3B1</i> primary CD34<sup>+</sup> cells and reduced mutant cell numbers in colony-forming assays. In contrast, normal hematopoietic progenitor cells were unaffected. Altogether, we here define <i>UBA1</i><sup>ms</sup> as a novel therapeutic vulnerability in <i>SF3B1</i>-mutant cells, introducing UBA1 inhibition as a potential avenue for future MDS-<i>SF3B1</i> treatments.</p><figure></figure>","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":"24 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144899260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
