Translating these mechanistic insights into the clinic, we evaluate the next-generation of therapeutic strategies, ranging from novel molecular biomarkers to rationally designed allosteric modulators and synthetic lethality. Finally, we discuss how deciphering these altered structural dynamics can guide the identification of splicing-derived neoantigens and biomarkers, establishing a roadmap for precision immunotherapy.

We corroborate our findings in an independent cohort of 625,328 Danish primary care patients. Our findings underscore the clinical relevance of CMUS and CCMUS as distinct high-risk states within the spectrum of clonal hematopoiesis, and establish an evidence base to refine their diagnostic definition.

The presence of a single MRG mutation did not confer a worse prognosis in favorable-risk AML, whereas a high MRG mutation burden (≥2 mutations) was independently associated with poorer LFS. This study suggests that quantifying the MRG mutation burden may inform risk stratification in this patient population.

According to ELN 2022, AML post-MDS mostly clustered in the adverse-risk group (84.1%), while t-AML showed more heterogeneous ELN profiles (12.9% favorable, 33.8% intermediate, and 53.3% adverse risk) reflecting diverse overall survival. Our findings underscore that genetic features and the ICC classification reliably capture disease biology, refine risk stratification, and ultimately guide treatment decisions in most secondary AML and MDS/AML.

Our findings support the Exon Regulon model of MDM2 splicing, regulated by distal elements analogous to distal enhancer elements that control transcription. These finding sheds light on intricacies in the splicing code that could have significant implications for developing splice variant targeting cancer therapies.

mTORC1 pathway inhibition using rapamycin normalized FYNB- and Srsf2P95H-induced impaired erythropoiesis and significantly increased erythroid colony formation of SRSF2-mutant myelodysplastic neoplasm (MDS) bone marrow cells. Our data reveal targetable molecular mechanisms of impaired erythropoiesis in SRSF2-mutant cells.

MRD based solely on secondary type mutations lacked predictive value, whereas MRD of non-DTA mutations in CR was associated with increased CIR in st-AML (subdistribution hazard ratio &lsqb;SHR] 3.25; P< .001). Molecularly defined st-AML, including st-MDS/AML, defines a distinct AML category with a unique genetic, clinical and treatment response profile, in which next-generation sequencing (NGS)-based MRD holds markedly prognostic significance.

This study evaluated the clinical efficacy of venetoclax and azacitidine (VEN+AZA) versus CAG (cytarabine, aclarubicin, and granulocyte colony-stimulating factor) for newly diagnosed adult acute myeloid leukemia (AML) unfit patients. 31.7 % (P = 0.20). Patients with age ≥ 60 y (EFS, P = 0.032), ECOG≥ 2 (EFS, P = 0.047), secondary AML (OS, P = 0.015; EFS, P = 0.039), ELN intermediate-adverse karyotype (OS, P = 0.034; EFS, P = 0.044), RUNX1 mutation (OS, P = 0.003; EFS, P = 0.003) and IDH1/2 mutation (EFS, P = 0.039) showed a preference for VEN+AZA regarding OS, and patients with SRSF2 mutation favored CAG in OS (P = 0.031).
