1.GSE276542 弥漫性大B细胞淋巴瘤免疫肿瘤微环境生态系统的空间转录组学特征

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、lymphoma、immune、tumor microenvironment、spatial、spatial transcriptomics、transcriptomics
  • 📝 描述:Contributors : Alba Diaz Herrero ; Pierre TonnerreSeries Type : OtherOrganism : Homo sapiensThis dataset comprises spatial transcriptomic profiles from 10 tissue samples of Diffuse Large B-cell Lymphoma (DLBCL) the most common subtype of non-Hodgkin’s lymphoma and secondary lymphoid organ controls (SLO). The diffuse nature of DLBCL challenges the analysis of cellular organization within the immune tumor microenvironment (TME). We employed spatial transcriptomics to map spatially-resolved gene expression patterns. The analysis led to the identification of six cellular ecosystems (Cell-Eco) that differ in cellular composition, functional patterns, and neighborhood characteristics. The spatially-resolved Cell-Eco signatures provided prognostic scores that stratified patients with different overall survival rates. We also found that C1q+ tumor-associated macrophages are the primary cells interacting with malignant B cells and influencing the spatial architecture of the TME. This resource offers valuable insights into the spatial complexity of the DLBCL microenvironment and its potential prognostic significance.

2.GSE328719 癌细胞内在的 SSBP4 通过促进胆固醇生物合成实现肿瘤免疫逃逸 [RNA-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、cancer、immune、RNA-seq
  • 📝 描述:Contributors : Ou Peiqi ; Eres Ittai ; Zhao Junjie ; Han Chia-Jung ; Oh Jaehak ; Kim Aeryon ; Dong Jiayi ; Zhou Hong ; Yamawaki Tracy ; Li Chi-Ming ; Rankin Andrew ; Noubade Rajkumar ; Yu XinSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusThe immunosuppressive tumor microenvironment (TME) contributes to resistance against checkpoint inhibitors. However, the precise factors that shape the immune contexture of the TME remain elusive. Here, we report that Single-Stranded DNA Binding Protein 4 (SSBP4), a previously uncharacterized protein, suppresses intratumoral T-cell activation by promoting excessive cholesteryl ester production in tumor cells. Overexpression of SSBP4 in tumor cells decreased T-cell infiltration and accelerated tumor growth in murine syngeneic tumor models. Conversely, genetic ablation of SSBP4 in tumor cells enhanced T-cell infiltration and inhibited tumor growth in a CD8+ T cell–-dependent manner. Mechanistically, SSBP4 upregulated cholesterol synthesis genes, leading to increased production of cholesterol and cholesteryl esters in tumor cells, which directly suppressed CD8+ T-cell activation and function. Furthermore, SSBP4 abrogation significantly improved the efficacy of anti-PD-1 treatment. Thus, in this study, we have identified SSBP4 as a cancer cell–intrinsic regulator of cholesterol metabolism that contributes to tumor immune evasion.

5.GSE307285 BRD2 上调作为泛癌对 BET 抑制的适应性耐药机制 [ChIP-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、resistance、ChIP-seq
  • 📝 描述:Contributors : Suyakarn Archasappawat ; Chang-il HwangSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusBromodomain and extraterminal motif (BET) inhibitors, such as JQ1, are promising cancer therapeutics that target epigenetic regulators, particularly BRD4. However, resistance to BET inhibitors (BETi) limits their clinical utility, necessitating a better understanding of adaptive mechanisms. We identified BRD2 upregulation as a conserved response to BET inhibition across multiple cancer types and hypothesized that BRD2 compensates for BRD4 loss, sustaining essential transcriptional programs during treatment. Consistent with this, BRD2 knockdown sensitized cancer cells to BETi in vitro, and combining BRD2 depletion and JQ1 treatment significantly impaired tumor growth in vivo. At the chromatin level, BRD2 and BRD4 ChIP-seq analysis of pancreatic cancer cells showed consistent BRD4 loss from chromatin after JQ1 treatment, while BRD2 displacement differed by sensitivity. Resistant cells maintained higher BRD2 occupancy than sensitive cells, suggesting a link between BRD2 retention and drug response. To dissect the underlying mechanism of BRD2 upregulation upon BET inhibition, we analyzed co-expression networks and observed that NFYA is co-expressed with BRD2 across diverse tissues and cancer types. Consistently, NFYA binds the BRD2 promoter. NFYA depletion abrogated BRD2 upregulation upon BETi treatment, indicating that NFYA is required for BRD2 induction following BET inhibition. Collectively, our findings establish BRD2 as a critical mediator of adaptive resistance to BETi in pan-cancer and identify NFYA as a novel transcriptional regulator of this process. Co-targeting BRD2 or its regulatory network offers a rational strategy to enhance the durability and efficacy of BET-based therapies.

9.GSE311100 通过单核和空间转录组学解码H19在胆汁淤积性肝损伤中的细胞类型和空间作用

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:spatial、spatial transcriptomics、transcriptomics
  • 📝 描述:Contributors : Grayson W Way ; Huiping ZhouSeries Type : Expression profiling by high throughput sequencing ; OtherOrganism : Mus musculusDespite recent advances, Primary Sclerosing Cholangitis (PSC)-a chronic obstructive biliary disease-still lacks effective therapies to prevent disease progression or the need for liver transplantation. Long non-coding RNA H19 (H19) has been implicated in promoting PSC disease progression. However, the underlying cell-specific and molecular mechanisms by which H19 contributes to PSC pathogenesis remain incompletely understood. Here we used single nucleus RNA sequencing (snRNAseq) and spatial transcriptomics to elucidate the cell- and spatial-specific expression alterations associated with H19 in the Mdr2KO PSC mouse model.

10.GSE299323 单细胞RNA测序结果显示HCM小鼠存在心脏纤维化和免疫微环境激活。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:immune、cardiac、scRNA
  • 📝 描述:Contributors : Nianwei Zhou ; Wenjun Wang ; Luman Wang ; Xianhong ShuSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusHypertrophic cardiomyopathy (HCM), the most prevalent inherited cardiovascular disorder, confers elevated risks of stroke, progressive heart failure, and sudden cardiac death. Emerging evidence suggests that myocardial inflammation may contribute to the progression and complications of HCM. While colchicine has demonstrated therapeutic potential in reducing adverse cardiovascular events through its pleiotropic anti-inflammatory mechanisms in other cardiac conditions, its efficacy profile in HCM populations have not been investigated. Our study offered preclinical evidence suggesting that colchicine may exhibit potential therapeutic efficacy in the treatment of HCM, thereby presenting a theoretical foundation for the application of colchicine in HCM.
