2.GSE296145 SPEN 缺失导致滤泡外弥漫性大 B 细胞淋巴瘤,该淋巴瘤具有女性特异性致死性和 TLR 通路治疗脆弱性。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:lymphoma、B cell、TLR、pathway
  • 📝 描述:Contributors : Benedikt Pelzer ; Matt Teater ; Cem Meydan ; Ari M MelnickSeries Type : Expression profiling by high throughput sequencing ; Genome binding/occupancy profiling by high throughput sequencing ; OtherOrganism : Mus musculusIn this study, we explore the interplay between SPEN and NOTCH2 truncating mutations, identifying an alternative, extra-follicular, trajectory of diffuse large B cell lymphomas (DLBCL) transformation. Our findings challenge the traditional germinal centre-centric model of lymphomagenesis, showing that marginal zone B cells (MZB) can give rise to aggressive lymphomas with autoimmune/aged B cells (AiBC)-like features, under the influence of these compound mutations. At a mechanistic level, we found that SPEN loss re-routes NOTCH2-driven transcriptional programs, promoting a ZEB2-driven cell fate that blocks plasmacytic differentiation and skews B cell identity toward a MZB/AiBC mixed phenotype. We further show that SPENTRUNC/NOTCH2TRUNC-mutant lymphomas are associated with reduced overall survival of female DLBCL patients, due to X-chromosomal transcriptional perturbations. By characterizing their unique molecular dependencies, we identify actionable features in this aggressive DLBCL subset, paving the way for new precision medicine strategies that address the disease’s heterogeneity.

3.GSE327372 小鼠正常乳腺成纤维细胞 (mNFs) 和 MMTV-PyMT 癌相关成纤维细胞 (mCAF1) 的表观遗传分析 (H3K27ac ChIP-seq)

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、ChIP-seq、epigenetic
  • 📝 描述:Contributors : Miguel Juliá ; Fernando CalvoSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusIn comparison with normal tissue fibroblast (normal fibroblasts, NFs), cancer-associated fibroblasts (CAFs) have pathologically activated phenotypes that impact in a wide variety of tumoral processes including cancer cell growth and invasion, extracellular matrix (ECM) remodelling, angiogenesis and immune suppression. These phenotypes result from the establishment of altered gene expression programs that may be further sustained through epigenetic alterations. However, how epigenetic rearrangements influence CAF behaviour is not well delineated. Here, we identify aspartoacylase (ASPA) as a metabolic enzyme consistently repressed in tumour stroma and CAFs. We report a reciprocal crosstalk between ASPA and Transforming Growth Factor Beta (TGFβ) signalling that influences fibroblast behaviour. TGFβ suppresses ASPA expression in fibroblasts, whereas ASPA restrains TGFβ-dependent myofibroblast conversion, ECM remodelling, angiogenesis and pro-tumoral macrophage phenotypes. TGFβ/SMAD3-dependent transcriptional repression may require the activity of histone deacetylases (HDACs), which participate in epigenetic rearrangements modulating gene expression. Epigenomic analysis of the 3’ regulatory regions at the Aspa locus in murine MMTV-PyMT-derived breast cancer CAFs (mCAF1) as compared to normal murine mammary gland fibroblasts (mNFs), revealed a selective loss of H3K27Ac, an epigenetic mark of active enhancers. As expected, bona fide CAF marker genes such as Acta2, Fap, Lrrc15 and others presented increased H3K27Ac signal at regulatory regions in mCAF1, whereas peaks at NF marker genes (Cxcl1 and Pi16) were decreased. Our findings unveil ASPA expression in fibroblasts as a previously unknown gatekeeper of TGFβ responses and activation in cancer progression.

4.GSE308260 小鼠胸腔内粘连的空间转录组学研究

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:spatial、spatial transcriptomics、transcriptomics
  • 📝 描述:Contributors : Tomohisa Sakaue ; Yu Mori ; Hironori IzutaniSeries Type : OtherOrganism : Mus musculusIntrathoracic adhesions (IAs) complicate thoracic surgery, causing risks such as bleeding, prolonged operative time, and postoperative air leakage. Severe adhesions (>10% pleura) often necessitate conversion from VATS to open thoracotomy due to dissection difficulties and pleural damage. Given the increasing role of lung segmentectomy and re-lobectomy for small or recurrent NSCLC, reoperations with IA are expected to rise, highlighting the need for effective IA prevention. This study aimed to establish such a murine IA model, evaluate pathological and gene expression changes, and identify targets to prevent lung–chest wall adhesions.

7. GSE300843 解析病毒感染过程中显性抗性基因的细胞类型特异性作用 [scRNA-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:resistance、scRNA
  • 📝 描述:Contributors : Yuhong Zhang ; Shan Bu ; Luyou Wang ; Jiayi Liu ; Junchen Xu ; Jiejun Peng ; Fei Yan ; Jian WuSeries Type : Expression profiling by high throughput sequencingOrganism : Solanum lycopersicumPlant viruses cause widespread crop epidemics, with resistance (R) genes playing key roles in plant defense by triggering responses that limit viral replication and spread. However, given the diversity of plant cell types and their developmental paths, the specific roles of R genes in distinct cell types remain unclear. Using tomato brown rugose fruit virus (ToBRFV), which partially overcomes the tobamovirus resistance gene Tm-22, this study employed single-cell RNA sequencing to explore infection dynamics and Tm-22-mediated responses at the cellular level. Results indicated that upon ToBRFV infection, the Tm-22 gene and the tm-2 allele, which carries a recessive form of Tm-22, differentially regulate the composition of cell types in tomato leaves. Tm-22 does not fully inhibit viral entry or movement during the early stages but selectively restricts viral replication or accumulation in certain cell types. ToBRFV differentially modulates signaling pathways depending on cell type and genotype, including Tm-22 and tm-2 homozygotes. Pseudotime analysis revealed that during mesophyll cell development in Tm-22 plants, ToBRFV reverses expression of BR positive regulators, but not negative ones; silencing these BR positive regulators increased infection in Tm-22 plants while suppressing it in tm-2 plants, linking BR signaling to Tm-22-dependent resistance. This study offers the first cell-type-specific insight into R gene function, showing how Tm-22 restrains ToBRFV accumulation through BR signaling pathways. It provides a valuable framework for future single-cell investigations of resistance genes, enhancing our understanding of plant-virus interactions.

8. GSE299489 LY6D 鉴定出驱动胰腺肿瘤发生的持续性肿瘤起始细胞 [ATAC-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、ATAC-seq
  • 📝 描述:Contributors : Juanjuan Shi ; Jing XueSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusPancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy driven by oncogenic KRAS and inflammation-induced cellular heterogeneity, yet the mechanisms underlying tumor-initiating cells (TICs) emergence and maintenance remain unclear. Our study establishes LY6D as a marker of persistent TICs that orchestrate pancreatic cancer progression across all disease stages. Single-cell RNA sequencing of inflammation-driven PDAC models reveals that LY6D+ TICs specifically originate from KRAS-mutant acinar-to-ductal metaplasia (ADM) lesions under inflammatory conditions, maintaining conserved stemness properties and exhibiting a distinctive oxidative phosphorylation (OXPHOS) dependency throughout tumor evolution. Moreover, genetic ablation of Ly6d in KrasG12D pancreata delays tumorigenesis, while forced Ly6d expression enhances tumorigenic potential and metastatic capability. Mechanistically, LY6D-despite lacking intracellular domains-scaffolds lipid raft-associated kinase networks and FOSL1-dependent epigenetic reprogramming to establish a stable pro-tumorigenic state. Clinically, LY6D+ cells are enriched in human PDAC and exhibit conserved stemness and epithelial-mesenchymal transition (EMT) properties. Strikingly, LY6D expression levels demonstrate PDAC-restricted prognostic power. Our work defines LY6D as pan-stage TICs marker linking cellular plasticity to PDAC initiation and progression, offering new avenues for early detection and interception of this lethal malignancy.
