We illustrate four use cases of ASHOP: (1) stratification of DUX4-rearranged B-cell leukemias into Early/Multipotent and Committed subgroups with distinct outcomes, (2) characterization of HOXA/HOXB expression patterns in acute myeloid leukemias, (3) correlating mutational burden with mismatch repair deficiency and mutational signatures, (4) investigation of TP53 alteration landscape. ASHOP is an open-access resource to inform genomic and transcriptomic data interpretation for hematologic malignancies, and will expand to support additional diseases and data modalities from the ASH community.
The present study suggests that SPINK1 may modulate glycolytic metabolism in lung cancer cells, inhibiting their growth and proliferation, and potentially providing therapeutic insights.
Additionally, we explore the mechanisms underlying TP53 mutations in the leukemic transformation of MPNs, including clonal evolution to multihit status and the role of inflammation and therapy. Finally, recent findings on the clinical impact of multihit TP53 mutations and potential strategies for targeting the p53 pathway in MPNs and sAML are presented.
Our findings suggest that reduced STAG2 protein expression plays a relevant role in MDS pathogenesis. Immunohistochemical assessment of STAG2 may be incorporated into the clinical workflows as a potential diagnostic and prognostic biomarker, as well as indicate therapeutic targets, particularly in association with complex karyotypes and trisomy 8.
In this study, we demonstrate that IDH1-mutant AML cells are markedly more sensitive to cuproptosis induced by the copper ionophore elesclomol (ES), compared to their wild-type counterparts...In vivo experiments confirm that ES more effectively suppresses tumor growth in IDH1-mutant xenografts. These findings uncover a copper-dependent metabolic vulnerability and provide a rationale for exploiting cuproptosis as a therapeutic strategy in IDH1-mutant AML.
