1.GSE301720 整合的单细胞和空间分析揭示了头颈癌免疫检查点阻断反应中依赖于上下文的髓系-T细胞相互作用

  • 📝 描述:Contributors : Athena E Golfinos-Owens ; Taja Lozar ; Parth Khatri ; Rong Hu ; Paul M Harari ; Paul F Lambert ; Megan B Fitzpatrick ; Huy Q DinhSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensBackground Approximately 15-20% of head and neck cancer squamous cell carcinoma (HNSCC) patients respond favorably to immune checkpoint blockade (ICB). Previous single-cell RNA-Seq (scRNA-Seq) studies identified immune features, including macrophage subset ratios and T-cell subtypes, in HNSCC ICB response. However, the spatial features of HNSCC-infiltrated immune cells in response to ICB treatment need to be better characterized.Methods Here, we perform a systematic evaluation of cell interactions between immune cell types within the tumor microenvironment using spatial omics data using complementary techniques from both 10X Visium spot-based spatial transcriptomics and Nanostring CosMx single-cell spatial omics with RNA gene panel including 435 ligands and receptors. In this study, we used integrated bioinformatics analyses to identify cellular neighborhoods of co-localizing cell types in single-cell spatial transcriptomics and proteomics data. In addition, we used both publicly available scRNA-Seq and in-house spatial RNA-Seq data to identify spatially constrained Ligand-Receptor interactions in Responder patients.Results With 522,399 single cells profiled with both RNA and protein from 26 patients, in addition to spot-resolved spatial RNA-Seq from 8 patients treated with ICB together with bioinformatics analysis of publicly available single-cell and bulk RNA-Seq, we have identified a spatial and cell-type specific context-dependency of myeloid and T cell interaction difference between Responders and Non-Responders. We defined further cellular neighborhood and the sources of chemokine CXCL9/10-CXCR3 interactions in Responders, emerging targets in ICB, as well as CXCL16-CXCR6, CCL4/5-CCR5, and other underappreciated and potential markers and targets for ICB response in HNSCC. In addition, we have contributed a rich data resource of cell-cell Ligand Receptor interactions for the immunotherapy and HNSCC research community.Discussion Our work provides a comprehensive single-cell and spatial atlas of immune cell interactions that correlate with response to ICB in HNSCC. We showcase how integrating multiple technologies and bioinformatics approaches can provide new insights into potential immune-based biomarkers of ICB response. Our …

2.GSE319270 多组学揭示维生素D在炎症性肠病中对免疫-肠道微生物群相互作用和耐受性通路的影响

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:immune、gut、regex:gut(-?microbiome)?
  • 📝 描述:Contributor : John GubatanSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensLoss of immune tolerance to the gut microbiome plays a pathogenic role in inflammatory bowel disease (IBD). How dietary factors alter host immune-gut microbiome interactions in IBD is unclear. Here, we apply multi-omics (IgA-SEQ, IgG-SEQ, blood scRNA-seq and immune repertoire sequencing) to investigate the effects of 12 weeks of vitamin D on host immune microbe interactions in patients with IBD. Vitamin D treatment associates with decreased disease activity and inflammatory markers and increased IgA-bound and decreased IgG-bound gut microbiota. Vitamin D alters the profiles of IgA-bound (increased Lachnospiraceae, Blautia) and IgG-bound (decreased Proteobacteria, Enterococcaceae) gut bacteria. Vitamin D increases BAFF signaling between plasmacytoid dendritic cells and B cells, alters BCR and TCR clonotypes that associate with Ig-bound gut microbiota, and increases α4β7+ B and T regulatory cells. Our results demonstrate that vitamin D promotes immune tolerance to gut microbiota in patients with IBD. Clinical trial is registered under NCT04828031

To investigate potential epigenetic drivers of immune resistance, this study evaluated transcriptional changes following pharmacological inhibition of the histone methyltransferase G9a (EHMT2). Bulk RNA sequencing was performed on the murine NM53 and human PLC/PRF/5 HCC cell lines treated with G9a inhibitors. NM53 cells were treated with CM272 with or without interferon gamma (IFN-gamma), and PLC/PRF/5 cells were treated with EZM8266. Gene-level expression was quantified for both cell lines, and transposable element (TE) family-level expression was quantified for NM53 samples.

6. GSE293444 STAT1 和 STAT3 信号通路在卵巢癌中的作用:预后生物标志物和治疗靶点 [RNA-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、RNA-seq
  • 📝 描述:Contributors : Esther Rodman ; John HawseSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensEpithelial ovarian cancer is the 7th most common cancer in women worldwide and is the most fatal of all female reproductive cancers. JAK/STAT signaling is oncogenic in ovarian cancer and has been reported to be constitutively active in a proportion of chemotherapy resistant ovarian cancer cell lines and tumors. However, the precise molecular mechanisms by which STAT1 and STAT3 function in ovarian cancer are not well understood and the consequences of their specific inhibition have yet to be determined. Methods: To delineate the specific functions of STAT1 and STAT3 in high grade serous and endometrioid ovarian cancer cell lines, we treated OVSAHO and MDAH cells with IFNγ or IL6, canonical STAT1 and STAT3 activators respectively, with and without STAT1 or STAT3 specific siRNAs. We conducted RNA-sequencing and ChIP-sequencing following treatment to delineate direct and indirect target genes for STAT1 and STAT3. We generated a STAT1 and STAT3 specific gene signature and applied them to publicly available datasets to test their predictive and prognostic ability. Results: Using these global and unbiased datasets, we identified STAT1 and STAT3 specific pathways, developed STAT1 and STAT3 specific gene signatures, and applied these signatures to publicly available ovarian cancer patient data. We determined the STAT1 and STAT3 signature’s associations with tumor development, chemotherapy responsiveness and long-term patient outcomes. Conclusions: Our studies have further informed the precise mechanisms of STAT1 and STAT3 action in the two most common subtypes of ovarian cancer and have defined gene signatures that are both prognostic and predictive.

  • 🏷️ 关键词:Alzheimer、transcriptome
  • 📝 描述:Contributors : Joshua Abd Alla ; Ursula QuittererSeries Type : Expression profiling by arrayOrganism : Mus musculusWith increased aging of the global society, the prevalence of Alzheimer’s Disease (AD) is on the rise worldwide. This study aimed to identify AD-related transcript changes in frontal cortex specimens of 18-month-old Tg2576 mice which were used as an experimental model of AD. This study analyzed frontal cortex specimens of two groups of 18-month-old Tg2576 AD mice. The first group was treated for 6 months with the GRK2 activity modulated, CPD10 [1-(1,3-Benzodioxol-5-yl)-4-(cyclopropanecarbonyl)-3-hydroxy-2-phenyl-2H-pyrrol-5-one] in drinking water (8 mg/kg/d) and the untreated control group of 18-month-old Tg2576 mice received tap water. The whole transcriptome microarray gene expression analysis identifies transcripts which were altered by treatment with the GRK2 activity modulator.

  • 🏷️ 关键词:inflammation
  • 📝 描述:For years, compulsive behaviors have been viewed as bad habits stuck on autopilot. But new research in rats found the opposite: inflammation in a key decision-making brain region actually made behavior more deliberate, not more automatic. The change was linked to astrocytes, brain support cells that multiplied and disrupted nearby circuits. The discovery hints that some compulsive behaviors may arise from excessive, misdirected control rather than a loss of it.
