Using lineage tracing, we find the tumor-initiating activity of ERG resides in a subpopulation of murine basal cells that coexpress luminal genes (BasalLum) and not in the larger population of ERG+ luminal cells. Upon ERG activation, BasalLum cells give rise to highly proliferative intermediate (IM) cells with stem-like features that coexpress basal, luminal, hillock and club marker genes, before transitioning to Krt8+ luminal cells. Transcriptomic analysis of ERG+ human prostate cancers confirms the presence of rare ERG+ BasalLum cells, as well as IM cells whose presence is associated with a worse prognosis. Single-cell analysis revealed a chromatin state in ERG+ IM cells enriched for STAT3 transcription factor binding sites and elevated expression of the KMT2A/MLL1 and DOT1L, all three of which are essential for ERG-driven tumorigenicity in vivo. In addition to providing translational opportunities, this work illustrates how single-cell approaches combined with lineage tracing can identify cancer vulnerabilities not evident from bulk analysis. Lineage tracing in mice identifies a subpopulation of basal cells that express Tmprss2 and Nkx3 as the origin of ERG-driven prostate cancer. Upon expansion, these cells show an enrichment for STAT3 chromatin binding and elevated expression of KMT2A and DOT1L as dependencies for ERG oncogenicity.","PeriodicalId":18985,"journal":{"name":"Nature genetics","volume":"57 9","pages":"2177-2191"},"PeriodicalIF":29.0,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41588-025-02289-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144900354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We unveiled a high-resolution mutational portrait of TNBC in AA women reminiscent of that in Asian and non-Hispanic white women, with no evidence of associations of mutational features with African ancestry. We also made some distinctive discoveries, including an almost complete dominance of TP53 mutations, low frequency of PIK3CA mutations and mutational signature-based subtypes with etiologic and prognostic significance. These findings do not support major racial differences in TNBC biology at the level of somatic mutations. Our study contributes considerably to diversifying the knowledge base of breast cancer genomics and provides insights into the disease etiology, disparities and therapeutic vulnerability of TNBC in AA women.

The association between tamoxifen therapy and secondary uterine cancers is uncommon but well established; however, the genetic mechanisms underlying tamoxifen-driven tumorigenesis remain unclear. We find that oncogenic PIK3CA mutations, common in spontaneously arising estrogen-associated de novo uterine cancer, are significantly less frequent in tamoxifen-associated tumors. In vivo, tamoxifen-induced estrogen receptor stimulation activates phosphoinositide 3-kinase (PI3K) signaling in normal mouse uterine tissue, potentially eliminating the selective benefit of PI3K-activating mutations in tamoxifen-associated uterine cancer. Together, we present a unique pathway of therapy-associated carcinogenesis in which tamoxifen-induced activation of the PI3K pathway acts as a non-genetic driver event, contributing to the multistep model of uterine carcinogenesis. While this PI3K mechanism is specific to tamoxifen-associated uterine cancer, the concept of treatment-induced signaling events may have broader applicability to other routes of tumorigenesis. Sequencing analysis of tamoxifen-associated uterine cancers and further in vivo analyses suggest that the drug tamoxifen can activate the PI3K pathway in the absence of oncogenic mutations.","PeriodicalId":18985,"journal":{"name":"Nature genetics","volume":"57 9","pages":"2192-2202"},"PeriodicalIF":29.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41588-025-02308-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144898390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inadequate expression of mSWI/SNF in heterozygous mice can lead to developmental defects, indicating dosage-sensitive effects of mSWI/SNF. However, how its dosage affects function has remained unclear. Using a targeted protein degradation system, we investigated its dosage-sensitive effects by precisely controlling protein levels of BRG1, the ATPase subunit of the mSWI/SNF complex. We found that binding of BRG1 to chromatin exhibited a linear response to the BRG1 protein level. Although chromatin accessibility at most promoters and insulators was largely unaffected by BRG1 depletion, 44% of enhancers, including 84% of defined superenhancers, showed reduced accessibility. Notably, half of the BRG1-regulated enhancers, particularly superenhancers, exhibited a buffered response to BRG1 loss. Consistently, transcription exhibited a predominantly buffered response to changes in BRG1 levels. Collectively, our findings demonstrate a genomic feature-specific response to BRG1 dosage, shedding light on the dosage-sensitive effects of mSWI/SNF complex defects in cancer and other diseases. This study investigates the dosage-sensitive effects of BRG1, a core SWI/SNF subunit, on chromatin binding, accessibility and transcriptional regulation by precisely controlling its protein level.","PeriodicalId":18985,"journal":{"name":"Nature genetics","volume":"57 9","pages":"2250-2263"},"PeriodicalIF":29.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41588-025-02305-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144898392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using clock-like mutational signatures, we estimated a time lag of two to four decades between the initiation of events and diagnosis. We demonstrate that odd-numbered chromosome trisomies in patients with hyperdiploidy can be acquired simultaneously with other chromosomal gains (for example, 1q gain). We show that hyperdiploidy is acquired after immunoglobulin heavy chain translocation when both events co-occur. Finally, patients with early 1q gain had adverse outcomes similar to those with 1q amplification (>1 extra copy), but fared worse than those with late 1q gain. This finding underscores that the 1q gain prognostic impact depends more on the timing of acquisition than on the number of copies gained. Overall, this study contributes to a better understanding of the life history of myeloma and may have prognostic implications. This analysis of whole-genome sequencing data from 421 multiple myeloma samples elucidates the timing of key genomic events and shows associations between the timing of 1q gain and clinical outcome.","PeriodicalId":18985,"journal":{"name":"Nature genetics","volume":"57 9","pages":"2203-2214"},"PeriodicalIF":29.0,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144898187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we analyze 27 genomes of Arabidopsis thaliana to illustrate these issues. Genome size variation is mostly due to tandem repeat regions that are difficult to assemble. However, while the rest of the genome varies little in length, it is full of structural variants, mostly due to transposon insertions. Because of this, the pangenome coordinate system grows rapidly with sample size and ultimately becomes 70% larger than the size of any single genome, even for n = 27. Finally, we show how short-read data are biased by read mapping. SNP calling is biased by the choice of reference genome, and both transcriptome and methylome profiling results are affected by mapping reads to a reference genome rather than to the genome of the assayed individual. New concepts for comparing the genomes of 27 naturally inbred Arabidopsis thaliana accessions provide essential insights into obtaining a less biased view of whole-genome polymorphism.","PeriodicalId":18985,"journal":{"name":"Nature genetics","volume":"57 9","pages":"2289-2301"},"PeriodicalIF":29.0,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41588-025-02293-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144883236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leveraging genome-wide chromatin tracing to visualize 3D genome folding directly in tissues, we generated 3D genome cancer atlases of oncogenic Kras-driven mouse lung adenocarcinoma (LUAD) and pancreatic ductal adenocarcinoma. Here we define nonmonotonic, stage-specific alterations in 3D genome compaction, heterogeneity and compartmentalization as cancers progress from normal to preinvasive and ultimately to invasive tumors, discovering a potential structural bottleneck in early tumor progression. Remarkably, 3D genome architectures distinguish morphologic cancer states in single cells, despite considerable cell-to-cell heterogeneity. Analyses of genome compartmentalization changes not only showed that compartment-associated genes are more homogeneously regulated but also elucidated prognostic and dependency genes in LUAD, as well as an unexpected role for Rnf2 in 3D genome regulation. Our results highlight the power of single-cell 3D genome mapping to identify diagnostic, prognostic and therapeutic biomarkers in cancer.</p>","PeriodicalId":18985,"journal":{"name":"Nature genetics","volume":" ","pages":""},"PeriodicalIF":29.0,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144874143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
