Several predictive and prognostic models are used but have considerable inaccuracy at individual level. We tried to increase prediction accuracy using a multi-omics strategy. We interrogated data from 1391 consecutive, newly diagnosed subjects with AML, integrating information on mutation topography, DNA methylation, and transcriptomics. We developed an unsupervised multi-omics classification system (UAMOCS) with these data. UAMOCS provides a multidimensional understanding of AML heterogeneity and stratifies subjects into three cohorts: (a) UAMOCS1 [high lymphocyte activating 3 (LAG3) expression, chromosome instability, myelodysplasia-related mutations]; (b) UAMOCS2 (monocytic-like profile, immune suppression and activated angiogenesis and hypoxia pathways); and (c) UAMOCS3 [CCAAT enhancer binding protein alpha (CEBPA) mutations and MYC pathway activation]. UAMOCS distinguishes overall survival rates across the cohorts (TCGA P = 0.042; GSE71014 P = 0.043; ihCAMs-AML, GSE102691 and GSE37642 all P < 0.001). The model's C-statistic is comparable to the 2022 ELN risk classification (0.87 vs 0.82; P = 0.162), but offers a more nuanced distinction between intermediate- and high-risk groups. When combined with high-throughput drug sensitivity testing, UAMOCS can accurately predict sensitivity to azacitidine (AZA) and venetoclax. The UAMOCS system is available as an R package. The UAMOCS system has the potential to redefine AML subtypes, enhance prognostic predictions, and guide treatment strategies based on patients' immune status and expected responses to therapies.</p>","PeriodicalId":18764,"journal":{"name":"Molecular Oncology","volume":" ","pages":"1836-1854"},"PeriodicalIF":6.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12161470/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143382782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is well accepted that etoposide triggers cell death due to DNA damage. Our results indicate that multiple molecular mechanisms contribute to etoposide-induced apoptosis, including the overexpression of the mitochondrial voltage-dependent anion channel 1 (VDAC1) and its oligomerization, forming a mega-channel that releases pro-apoptotic proteins, thereby activating apoptosis. Etoposide induces C-terminal truncation of VDAC1 (VDAC1-ΔC) via the proteolytic actions of calpain-1 and asparagine endopeptidase (AEP). A calpain-specific inhibitor effectively prevented etoposide-induced VDAC1-ΔC formation, apoptosis, and the nuclear translocation of apoptosis-inducing factor (AIF). Additionally, etoposide upregulates the expression levels of apoptosis regulators (p53, Bax, p21, AIF) and of the proteases calpain and AEP. Etoposide-induced apoptosis and VDAC1 truncation are cell-type dependent and associated with calpain levels and activity. Etoposide-induced VDAC1-ΔC formation and apoptosis are tightly linked: as both display similar patterns of concentration- and time-dependence, both are inhibited by calpain and AEP inhibitors, as well as the VDAC1 oligomerization inhibitor VBIT-4, and are dependent on intracellular Ca<sup>2+</sup>.

Current clinicopathological factors inadequately predict biochemical recurrence, a critical indicator guiding post-treatment strategies following radical prostatectomy. To address this, we conducted a meta-analysis of four large-scale PCa datasets and found 33 previously reported PCa-associated genes to be consistently up-regulated in prostate tumours. By analysing single-cell RNA-sequencing data, we found these genes predominantly as markers in epithelial cells. Subsequently, we applied 97 advanced machine-learning algorithms across five PCa cohorts and developed an 11-gene epithelial expression signature. This signature robustly predicted biochemical recurrence-free survival (BCRFS) and stratified patients into distinct risk categories, with high-risk patients showing worse survival and altered immune cell populations. The signature outperformed traditional clinical parameters in larger cohorts and was overall superior to published PCa signatures for BCRFS. By analysing peripheral blood data, four of our signature genes showed potential as biomarkers for radiation response in patients with localised cancer and effectively stratified castration-resistant patients for overall survival. In conclusion, this study developed a novel epithelial gene-expression signature that enhanced BCRFS prediction and enabled effective risk stratification compared to existing clinical- and gene-expression-derived prognostic tools. Furthermore, a set of genes from the signature demonstrated potential utility in peripheral blood, a tissue amenable to minimally invasive sampling in a primary care setting, offering significant prognostic value for PCa patients without requiring a tumour biopsy.</p>","PeriodicalId":18764,"journal":{"name":"Molecular Oncology","volume":" ","pages":"1811-1835"},"PeriodicalIF":6.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12161480/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143458668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
