Strikingly, GSR depletion also enhanced sensitivity to cuproptosis triggered by the copper ionophore Es. In multiple in vivo tumor models, GSR inhibition synergizes with RSL3 or Es to suppress tumor growth, inhibit lung metastasis, and prolong survival. Mechanistically, GSR deficiency amplified ROS production, induced mitochondrial stress, and triggered the cytosolic mitochondrial DNA release under ferroptotic or cuproptotic stress, activating the cGAS-STING pathway in vitro and in vivo. This increased inflammatory cytokine production, promoted immunogenic cell death, and enhanced the release of damage-associated molecular patterns (DAMPs), including HMGB1.

A defining feature of aggressive PC is its propensity for perineural invasion (PNI), a pathological finding that is associated with poor prognosis. Despite its clinical significance, very little is known about the spatial and molecular determinants of PNI in PC. To address this, we used high-definition spatial transcriptomics (Visium HD) to profile the PNI-associated tumor microenvironment (TME) of a representative PC patient at near single-cell resolution. Spatial mapping of the expressed genes and inferred cell types revealed transcriptionally divergent malignant cell states spatially linked to PNI within this patient. Nerve-invasive PC cells were organized within a distinct spatially localized niche that exhibited altered TME characteristics, including increased proportions of macrophages, CD4 T-cells, and endothelial cells, suggesting coordinated changes in the tumor- and immune microenvironments. The PNI-associated niche in this patient further displayed enrichment of pathways involved in immune regulation and extracellular matrix remodeling, consistent with PNI-associated niche remodeling. APP-CD74 was identified as a potential signaling axis associated with tumor-nerve, nerve-macrophage, and nerve-endothelial cell interactions, suggesting PNI in this patient may be associated with distinct microenvironmental signaling programs. We further revealed a PNI-associated PC signature that held biomarker potential at the early-localized and advanced-metastatic disease stages. Although based on a single patient, these results contribute to our understanding of the spatial and molecular features of PNI in PC and may help guide personalized treatment choices for PC patients in the future.</p>","PeriodicalId":16023,"journal":{"name":"Journal of Hematology & Oncology","volume":"19 1","pages":""},"PeriodicalIF":47.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13531779/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148873136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This correspondence highlights how the first-in-class pan-RAS (ON) inhibitor daraxonrasib (RMC-6236) virtually doubled median overall survival (13.2 vs. 6.6 months) and progression-free survival compared to chemotherapy in second-line mPDAC, establishing a new standard of care.

Furthermore, we address the KRAS G12C cohort where farnesyl transferase co-inhibition (darlifarnib plus adagrasib) successfully bypasses adaptive resistance. Ultimately, the therapeutic landscape of mPDAC is transitioning toward tailored genomic frameworks.
