1.GSE325337 RANKL inhibits macrophage pro-inflammatory Toll-like receptor 2 and 4 signaling and impairs killing of intracellular bacteria

  • 🏷️ 关键词:bacteria、macrophage、Toll-like receptor、regex:bacter(ia|ial|ium)
  • 📝 描述:Contributors : Clara D Si ; Christopher T Peek ; Sana R Fatah ; Andrew J Beaudoin ; Anton R Zhelonkin ; Kara R Eichelberger ; Stacy L Hahn ; Robert O Watson ; Denis A Mogilenko ; James E CassatSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusMonocyte-macrophage lineage cells, crucial components of the innate immune system, can uniquely form bone-resorbing osteoclasts upon exposure to the cytokine receptor activator of NF-κB ligand (RANKL) in the bone microenvironment. Recent studies have also begun to uncover extensive extraskeletal roles of RANKL. However, how monocyte-macrophage lineage cells respond to RANKL outside of the bone, and the impact that this signaling pathway exerts on the host immune response, is not fully understood. In this study, we sought to define how RANKL exposure shapes the macrophage inflammatory response to pathogens by using the model intracellular bacterium Salmonella enterica serovar Typhimurium (STm), which co-opts macrophages to cause life-threatening infections. We found that exposing both mouse and human macrophages to sub-osteoclastogenic levels of RANKL increased intracellular STm burdens and decreased pro-inflammatory cytokine production. RNA sequencing revealed downregulation of pattern recognition receptor (PRR) signaling pathways in RANKL-treated macrophages during the early stages of infection. Therefore, we hypothesized that RANKL impairs PRR-dependent signaling pathways that are important for pro-inflammatory cytokine production. We discovered that RANKL-treated macrophages exhibit reduced NF-κB and IRF3 activation, specifically in response to Toll-like receptor (TLR) 2 and TLR4 stimulation. We determined that prior RANKL exposure decreases abundance of the TLR2 and TLR4 adaptor proteins TRAM and TIRAP. Together, these data suggest that RANKL exposure negatively impacts the macrophage TLR-mediated inflammatory response to bacteria.

2.GSE289299 Syrah:最大化空间转录组数据输出的流程

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:spatial、spatial transcriptomics、transcriptomics
  • 📝 描述:Contributors : Carolyn E Brewster ; Frederick G Mann Jr ; Blair Benham-Pyle ; Alejandro Sánchez AlvaradoSeries Type : OtherOrganism : Schmidtea mediterraneaSpatial analysis of gene expression patterns has been a key technique for revealing the functions of genes. Traditionally, these analyses were constrained to examining only a few candidate genes per sample. However, the advent of spatial transcriptomic techniques like Slide-seqV2 has transformed this field, enabling unbiased and massively parallel exploration of gene expression patterns within their tissue contexts through RNA sequencing. Despite its potential, Slide-seq datasets often suffer from low read counts, loss of data points, and poor quality. We have identified that a significant source of these errors stems from the chemical synthesis of mRNA capture oligonucleotides used in Slide-seqV2. To address this issue, we have developed “Syrah,” an analysis pipeline designed to correct these errors. Syrah can dramatically enhance Slide-seqV2 datasets by recovering nearly 30% more reads. Unlike other dataset improvement methods that rely on complex mathematical imputation or single-cell RNA-seq references, Syrah operates independently, requiring no additional datasets or intricate calculations. This innovative technique promises to salvage previously unusable Slide-seq datasets by restoring valuable reads that were inadvertently discarded during analysis.

4.GSE298128 蛋白质稳态维持 T 细胞分化潜能和肿瘤浸润淋巴细胞功能 [RNA-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、T cell、RNA-seq
  • 📝 描述:Contributors : Nicole E Scharping ; Ananda W GoldrathSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusCD8+ tumor-infiltrating lymphocytes (TIL) often fail to restrain tumor growth due to differentiation to T cell exhaustion. In healthy tissues, tissue-resident memory T cells (TRM) survey tissues and sustain protective capacity for years, and tumors that contain TIL with TRM-features are associated with better patient prognosis. We identified protein homeostasis (proteostasis) significant in distinguishing TRM and progenitor-exhausted TIL (TPEX) from terminally-exhausted TIL (TEX) by identifying multiple E3 ubiquitin ligases that maintain T cell differentiation potential. Sustained ligase-expression in TIL enhanced T cell accumulation, preserved stem-like TCF1+ populations, and improved anti-tumor function, whereas ligase loss-of-function impaired TIL and altered T cell differentiation in acute infection. TEX experience a loss of proteostasis, marked by unfolded protein accumulation despite functional proteasomes. Enforced ligase expression rescued this unfolded protein accumulation in TIL and improved immunotherapy responses, demonstrating the role of proteostasis in maintaining differentiation potential and identifying new avenues for advancing cancer immunotherapies.

5. GSE313622 结合显微镜和蛋白质组学分析,对共生细菌 Candidatus Erwinia dacicola 与成年橄榄果蝇 Bactrocera oleae 的相互作用有了新的认识

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:regex:bacter(ia|ial|ium)、proteomics
  • 📝 描述:Contributors : Georgia Pantidi ; Ioannis Livadaras ; Evangelia Skoufa ; Emmanuel Spanoudakis ; Sofia Kaforou ; Christos Andronis ; John Vontas ; Inga Siden-KiamosSeries Type : Expression profiling by high throughput sequencingOrganism : Bactrocera oleaeThe olive fruit fly Bactrocera oleae is the major pest of olive production. The fly is dependent upon the symbiotic bacterium Candidatus Erwinia dacicola for the survival of the larvae in unripe olives, and in the adult stage they enhance fecundity. A major site of symbiont colonization is the esophageal bulb, yet the molecular interactions within this tissue remain poorly understood. To investigate host gene expression in this symbiont-bearing organ, we performed a transcriptomic analysis of B. oleae esophageal bulbs. This dataset provides a foundational resource for elucidating the functional biology of this organ and offers insights into insect–microbe symbiosis.

6. GSE294258 细胞内铁稳态调控的表观遗传重编程导致 -7/del(7q) 白血病

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:leukemia、epigenetic
  • 📝 描述:Contributors : Yiman Peng ; Jianan Zheng ; Xintong Deng ; Zhongwang WangSeries Type : Expression profiling by high throughput sequencing ; Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusChromosome copy number variations (CNVs) are among the most critical yet poorly understood genetic drivers of human malignancies. -7/del(7q) is one of the most common CNVs in acute myeloid leukemia (AML) and is associated with poor prognosis. It has been proposed that there might be multiple tumor suppressor genes (TSGs) in these CNVs. Previously, we identified KMT2C, a histone methyltransferase, as a tumor suppressor gene in chromosome 7q. In this study, we performed a differentiation CRISPR screening of hematopoietic stem and progenitor cells (HSPCs) and discovered that ABCB8, encoding a mitochondrial iron transporter, is essential for HSPC differentiation. ABCB8 deficiency accelerated leukemogenesis in vivo and disrupted iron homeostasis, reducing cytoplasmic iron availability and impairing iron-dependent enzymes, including the histone demethylase KDM6A. Consequently, ABCB8 loss elevated H3K27me3 levels, repressing differentiation genes in an iron- and KDM6A-dependent manner. Notably, ABCB8 and KMT2C, neighboring genes on 7q, cooperatively regulated H3K27me3 to suppress leukemogenesis. Our findings reveal ABCB8 as a novel TSG in -7/del(7q) AML and uncover an unprecedented epigenetic collaboration between neighboring TSGs, driven by iron-mediated chromatin remodeling.

7. GSE328504 CBFA2T3-GLIS2 融合介导的 mSWI/SNF 染色质重塑因子破坏在 AMKL 中产生癌症特异性依赖性 [ATAC-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、ATAC-seq
  • 📝 描述:Contributors : Gabe Boyle ; Alexander W Ying ; Jay SarthySeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensTranscription factor (TF) fusion oncoproteins are frequently associated with poor prognosis and remain challenging therapeutic targets. Here we show that the CBFA2T3-GLIS2 (C/G) fusion oncoprotein present in lethal pediatric acute megakaryocytic leukemias (AMKLs) co-opts mSWI/SNF chromatin remodeling complexes, reprogramming regulatory element architecture to sustain aberrant cell cycle progression. The C/G fusion binds to and redistributes mSWI/SNF complexes via the SMARCD1 SWIFT domain and targets complexes to oncogenic enhancers including those bound by ETS family TFs and the G1 cyclin CCND2, a C/G AML-specific dependency. Pharmacologic inhibition of mSWI/SNF-mediated G1 cell cycle phasing via FHD-286 suppresses C/G-driven gene expression programs, induces G1 arrest and apoptosis in cells, and reduces leukemic burden and extends survival in aggressive C/G AML in vivo. These findings define an oncogenic mSWI/SNF–G1 axis in C/G AML and establish a therapeutic framework for targeting chromatin dysfunction-mediated cell cycle aberrancy in high-risk pediatric leukemias.

10. GSE284330 大规模并行功能表征揭示肠道菌群对调控DNA元件的调控

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:gut、regex:gut(-?microbiome)?
  • 📝 描述:Contributors : Chadmirah Zaratiana ; Tiffany Liu ; Yong-An Lee ; Agnes Ong ; Samantha Chang ; Torsten Wuestefeld ; Poshen B ChenSeries Type : OtherOrganism : Homo sapiens ; Mus musculusThe human genome contains millions of DNA cis-regulatory elements (CREs) that regulate gene expression across different cell types. In liver hepatocytes, CREs enable adaptation to environmental changes by modifying transcriptomes, particularly in response to gut microbiome signals, which are linked to liver diseases. However, our understanding of the functionality of CREs and their responses to gut microbiota signals in vivo remains limited. To address this, we conducted a genome-wide multiplexed reporter assay (MPRA) to map functional CREs in the liver. Using this functional catalog, we discovered a rare functional variant associated with hepatocellular carcinoma in the Asian population that disrupts CRE activity. Additionally, we identify functional CREs regulated by gut microbiota. Overall, this study enhances our understanding of functional CREs and highlights the complex interactions between the gut microbiome and host gene regulation.
