Using single‑cell RNA sequencing and spatial transcriptomics, we characterized CD8⁺ exhausted T (Tex) cells in pancreatic ductal adenocarcinoma (PDAC). We generated single‑cell profiles from PDAC tumors and matched peripheral blood mononuclear cells, and performed T cell sub‑analysis. We found CXCL13 upregulated and GZMK downregulated in CD8⁺ Tex cells. Cell‑cell interaction analysis showed that T cells most frequently interacted with myeloid cells and cancer cells via ligand‑receptor pairs; INHBA⁺ macrophages and cancer cells communicated most with CD8⁺ Tex cells. Two key LR pairs (SPP1–integrin α4β1 and PLAUR–integrin α4β1) mediated crosstalk between cancer cells and CD8⁺ Tex cells, confirmed by immunofluorescence, spatial mapping, and protein docking. High SPP1 and PLAUR expression correlated with poor prognosis in TCGA‑PAAD. These findings provide a resource for understanding CD8⁺ T cell exhaustion in PDAC.

  • 📝 描述:Contributors : Honglin Tang ; Xiaojie Xu ; Lilong Liu ; Silu Tan ; Chongzhi Wu ; Zijian Shen ; Bowen Li ; Tingting Yuan ; Da Li ; Shipeng Ning ; Yuan PingSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusTumor cells often outcompete T cells for methionine, impairing T cell function and immune surveillance. However, selectively targeting methionine metabolism in tumors remains challenging. Here, we develop a Wnt-activated RNA editing nanoplatform (TREND) to specifically disrupt the tumor methionine transporter SLC43A2 and reprogram the metabolic competition between tumor cells and CD8+ T cells. By taking advantages of aberrant Wnt signaling pathway in tumor cells, we first established a Wnt-responsive promoter which was used to control the transcription of the plasmid encoding RNA editor (CasRx) targeting SLC43A2, in order to ensure RNA editing in tumor cells with activated Wnt signaling. To further promote the accumulation and the intracellular translocation of CasRx in the tumor cells in vivo, a tumor-targeted delivery system was engineered by cloaking hybrid cell membrane over the polymeric carriers for the systemic delivery of CasRx plasmid. Such a therapeutic strategy combining tumor-targeted delivery and tumor-specific RNA editing greatly relieves the metabolic competition of methionine between tumor cells and T cells, restores H3K79me2 and STAT5 expression and increases intracellular glutathione (GSH) to suppress ROS-driven activation of the NFAT/NR4a/Tox exhaustion axis, thereby reducing immune checkpoint expression. This strategy significantly boosts the activity of T-cell effectors and suppresses the progression of tumors in multiple mouse models, providing a modular and programmable RNA-based approach for tumor-targeted metabolic immunotherapy.

Despite endomyocardial biopsy (EMB) transcriptome enriching our understanding of DCM, the link between its gene expression and phenotype remains unclear. RNA-seq analysis of 58 DCM samples and 12 publicly available control samples unveiled about 25,000 transcripts. A principal component analysis highlighted a distinct DCM-control separation. WGCNA revealed four transcriptome modules strongly associated with DCM. The purple module, which is the DCM-related module, was enriched with fibrosis-related genes and showed FSTL3 as a pivotal DCM-associated gene.

The prevailing view is that omental adipocytes promote tumor growth by providinglipids, since global FABP4 deficiency curbs tumor growth. Here, we generated mice lacking mature adipocytes in the peritoneum and omentum. ID8p53–/–Brca2–/– , BPPNM, and KPCA OC cells retained a propensity to seed at regions typically associated with adipocytes, even without mature adipocytes. However, lack of mature adipocytes did not suppress peritoneal OC expansion, whereas removing the adipocyte-free omentum did. Murine and human single-cell RNA sequencing analysis revealed that endothelial FABP4 was high in the omentum. Indeed, endothelial cell-selective deficiency of FABP4 reduced OC growth in the peritoneum. These findings prompt a re-evaluation of adipocyte contributions to OC progression and point to a key role of the omental vasculature in supporting OC growth metabolically.

6.GSE304945 肿瘤来源的ADAMTSL4通过TGFβ信号通路驱动癌症恶病质

Whereas CCx is associated with reduced quality of life and poor survival, no approved pharmacological intervention exists. Here we show that elevated circulating levels of the tumour-derived glycoprotein ADAMTSL4 were associated with weight loss in various preclinical CCx models as well as in cachectic patients with different cancers. ADAMTSL4 overexpression in non-cachexia-inducing tumour cells conferred cachexia-inducing properties upon exposure of cultured myocytes and adipocytes as well as implantation in mice. Reversely, genetic ADAMTSL4 deletion in cachexia-inducing cancer cells markedly repressed wasting phenotypes both in vitro and in vivo. Ligand-receptor capture technology identified the latency-associated peptide of TGF-β1 as ADAMTSL4 target on muscle cell surface. ADAMTSL4 mediated muscle atrophy and adipose tissue wasting through local TGF-β1 activation, sensitive to inhibition of TGFβR1 or knockdown of proTGF-β1. Given the conserved correlation between circulating ADAMTSL4 and skeletal muscle TGF pathway component expression in an independent human cancer patient cohort, our data suggest that blockade of ADAMTSL4 function represents a first rational approach towards efficient cancer cachexia pharmacotherapy.

7. GSE328601 肌肉质膜渗漏过多会破坏细胞外基质含量并改变巨噬细胞介导的肌肉修复 [scRNA-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:macrophage、scRNA
  • 📝 描述:Contributors : GaHyun Lee ; Lauren Vaught ; Dorothy DeBiasse ; Alexis Demonbreun ; Elizabeth McNallySeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusPlasma membrane repair is critical for tissue integrity, especially for elongated contractile muscle cells. Genetically-mediated defects in plasma membrane resealing produce persistent leak, leading to a disordered extracellular matrix. Loss of the membrane repair protein dysferlin slows sarcolemmal resealing and promotes excess leak. Annexin A6 is also implicated in sarcolemmal repair, forming repair caps at the site of membrane disruption. On its own, deletion of the gene for annexin A6, Anxa6, had little effect on muscle health. In contrast, combined loss of dysferlin and annexin A6 (DysfA6) generated muscle fibers with profoundly defective membrane leak. Strikingly, Anxa6 deletion in the context of loss of dystrophin (mdxA6) did not exacerbate muscle defects. The persistent membrane leak in DysfA6 muscle resulted in marked macrophage infiltration with disordered macrophage polarization. Injured muscle fibers were targets of macrophage efferocytosis. Loss of Anxa6 was associated with increased expression of annexins A1 and A2, both of which were heavily deposited into the extracellular matrix. In vitro, macrophages exposed to annexins A1 and A2 expressed increased Csf1, consistent with a model where excess leak results in annexins A1 and A2 in the extracellular matrix, where this protein composition elicits macrophage proliferation and efferocytosis.

8. GSE314776 解码 3D 染色质结构揭示前列腺癌中分层基因调控背后的不同增强子类别 [ChIP-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、ChIP-seq
  • 📝 描述:Contributors : Huan Cao ; Zexun Wu ; Baixi Ji ; Seolyn Yang ; Leonardo Gonzalez-Smith ; Suhn RhieSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensBackground: The transcription process is controlled by non-coding regulatory elements, more than 70% of which are putative enhancers. These enhancers comprise over 600,000 regions and are marked by histone modifications. However, the mechanisms by which altered enhancers in cancer cooperate within the three-dimensional chromatin architecture to drive oncogenic programs remain poorly understood. Results: By integrating 201 H3K27ac ChIP seq datasets from prostate, we identify 3,216 high confidence prostate cancer-specific putative enhancers. Ultra high resolution chromatin interaction profiling by Region Capture Micro-C at a representative chr6q24.1 locus reveals that these enhancers form cancer specific, highly nested interactions with promoters that coalesce into a multi connected hub absent in normal prostate cells. CRISPR/Cas9 perturbations of these enhancers, examined one by one, distinguish enhancer classes within the hub. Deletion of a central enhancer collapses hub-wide enhancer activities and architecture, leading to the downregulation of target genes, impaired proliferation, and reduced clonogenic growth. In contrast, deletion of a redundant enhancer results in minimal transcriptional changes, as neighboring enhancers rescue cancer signaling through compensatory architectural rewiring that strengthens alternative enhancer-promoter interactions. We also observe that FOXA1, a pioneer transcription factor activated in prostate cancer, directly binds to these enhancers and regulates distinct enhancer classes, leading to varying degrees of chromatin accessibility and gene expression changes.Conclusions: These findings suggest that enhancers function in a coordinated manner, forming multi-connected cancer-specific chromatin interaction hubs, with distinct enhancer classes contributing differently to gene regulation. This study advances our ability to modulate gene expression in a cell type-specific manner, opening new avenues for precision therapies.
