1.GSE317527 整合的批量和单细胞转录组分析揭示了环磷酰胺对三阴性乳腺癌模型肿瘤微环境的影响 [scRNA-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、cancer、tumor microenvironment、single-cell、scRNA、transcriptome
  • 📝 描述:Contributors : Ling Zuo ; Jia Ge ; Xiaorong ZhouSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusTriple-negative breast cancer (TNBC) remains a formidable clinical challenge. Although preclinical investigations utilizing TNBC mouse models have demonstrated that intermittent cyclophosphamide (CTX) treatment yields superior anti-tumor effects, partly through immune stimulation, mechanisms by which CTX modulates the tumor microenvironment (TME) are not yet fully understood. In this study, we assessed the impact of optimal (140 mg/kg every 6 days, C140) and suboptimal (100 mg/kg every 6 days, C100) CTX treatment regimens on 4T1 tumors, a widely utilized orthotopic TNBC mouse model. While the C100 regimen was better tolerated than the C140 regimen, it was less effective in inhibiting tumor growth. Through integrated bulk and single-cell RNA sequencing of tumor tissues, we discovered that CTX treatment not only inhibited cancer cell proliferation and epithelial-mesenchymal transition but also remodeled the TME by recruiting and reprogramming various immune cells, thereby enhancing the anticancer immune response in a dose-dependent manner. Although the C140 regimen demonstrated significant tumor suppression, it also induced notable extracellular matrix remodeling and led to the accumulation of cancer-associated fibroblasts within the tumor microenvironment. Furthermore, the C140 regimen caused considerable exhaustion of CD8+ T cells and was linked to increased expression of various immune checkpoint molecules, including PD-L1/PD-L2, CD39, and CD200. These effects may compromise therapeutic efficacy and potentially contribute to the development of drug resistance. Overall, our findings elucidate both cancer-cell-intrinsic and tumor microenvironment-dependent mechanisms of CTX action at both local and systemic levels, highlighting potential targets for optimizing chemoimmunotherapy in TNBC.

4.GSE337339 RNA 和 DNA 相互作用组的单细胞整合分析揭示了癌症中可靶向的染色质结构 [scBarcode 测序]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、sequencing、single-cell
  • 📝 描述:Contributor : Evgeny DeforzhSeries Type : OtherOrganism : Homo sapiensThe human genome is pervasively transcribed into protein-coding and regulatory non-coding RNAs whose functions are coordinated within higher-order nuclear architectures. However, direct mapping of RNA–RNA and DNA–DNA interaction networks in complex human tissues at single-cell resolution has remained a major challenge. Here, we present SCIENCE-seq, a multimodal single-cell interactomics platform enabling simultaneous detection of RNA–RNA interactions and chromatin DNA–DNA contacts within individual cells. Applied to primary glioma specimens, SCIENCE-seq reveals cancer-specific interactions organized by lncRNAs and centered on key oncogenic drivers, including EGFR, hTERT, SOX2, CDK6, CDC42, CD47, and HOX loci. These datasets uncover previously unrecognized molecular relationships between premature lncRNAs and pre-mRNAs that regulate transcription, alternative splicing, and polyadenylation. Notably, we identify a glioma-specific trans-chromosomal HOX hub driven by five interacting lncRNAs. Targeting these RNA and DNA interactions with steric antisense oligonucleotides (ASOs) or CRISPRi enables selective inhibition of oncogenic programs in malignant cells while sparing normal tissue, establishing chromatin interactomes as actionable therapeutic targets.

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:spatial、spatial transcriptomics、transcriptomics
  • 📝 描述:Contributors : Jinhee Bae ; Heh-In ImSeries Type : OtherOrganism : Mus musculusChronic stress alters striatal functions involved in motivation, action selection, and behavioral adaptation, yet cell-type-associated transcriptional organization in the dorsal striatum remains unclear. We used RNAscope-guided GeoMx spatial transcriptomics to compare D1- and D2-enriched neuronal compartments within anatomically matched dorsal striatal regions after chronic restraint stress. Chronic restraint stress engaged both populations and produced comparable numbers of differentially expressed genes. Pathway-level analysis revealed partially overlapping transcriptional attenuation in D1 and D2 neurons, whereas D2 responses showed more coherent organization around receptor-trafficking and synaptic signaling programs. CRS-downregulated D2 genes further resolved into synapse-centered functional categories, including glutamatergic synapse, postsynaptic organization, and dendritic spine.

8.GSE337578 小鼠脑组织空间转录组学分析(tMCAO后3天)

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:spatial、spatial transcriptomics、transcriptomics
  • 📝 描述:Contributors : Yueman Zhang ; Yonghui Chen ; Yue ChengSeries Type : OtherOrganism : Mus musculusThis study employed spatial transcriptomics to profile the expression and spatial distribution of Htr2b, P2ry12, Mrc1, and Ms4a7 in mouse brains 3 days after transient middle cerebral artery occlusion (tMCAO). By capturing genome‑wide transcriptional data with spatial coordinates, we aimed to map the regional expression patterns of these genes across the ischemic core, penumbra, and remote areas, and to delineate their co‑localization relationships with distinct immune and glial cell populations. This spatially resolved approach will provide insights into the topographic organization of serotonergic signaling and neuroimmune interactions during the acute phase of ischemic stroke.

9.GSE327645 BACH1 作为先锋抑制因子,能够使巨噬细胞在不同组织和炎症环境中表现出可塑性和适应性 [RNA-seq/ATAC-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:macrophage、RNA-seq、ATAC-seq
  • 📝 描述:Contributors : Laszlo Nagy ; Dora Bojcsuk ; Petros TzerposSeries Type : Expression profiling by high throughput sequencing ; Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusTranscriptional master regulators of the myeloid lineage (like PU.1, Cebpa/b, etc.) are believed to be the main drivers of chromatin reprogramming during differentiation and polarization. Such developmental transcription factors act via their pioneer ability to open chromatin de novo and bookmark genomic regulatory sites (enhancers and promoters) to later recruit signal-dependent TFs, co-factors, and the basal transcriptional machinery. However, recent studies by us and others challenged this “developmental TF-centric” mode as they suggested that signal-dependent TFs, particularly repressors, can also have a pioneer and thus safeguarding role in the MF epigenome at baseline and during acute inflammation. Such an expanded model predicts that active transcriptional repression and chromatin bookmarking by signal-dependent master regulators are key mechanisms for safeguarding the enhancer repertoire and proper priming, deployment, and resolution of an inflammatory response. Here, we show that BACH1, a heme-sensitive transcriptional repressor, acts as such a pervasive epigenomic safeguard to regulate tissue macrophage identity. We show that BACH1 is part of the core hardwired transcriptional program of ground-state macrophages shaping the chromatin accessibility of thousands of distal regulatory elements. Furthermore, BACH1 cistrome is extensive, not static but dynamic, and expanding upon different inflammatory stimuli and correlates with pre-formed and de novo formed enhancer-promoter networks. We further show that myeloid BACH1 is indispensable in vivo for tissue regeneration upon injury as it regulates the kinetics of Ly6C+ to Ly6C- transition of inflammatory macrophages and regulates the onset, the kinetics and magnitude of expression of critical inflammatory and repair-related genes. Finally, BACH1 was found to be required in vivo for competitive fitness and tissue adaptation of several tissue-resident macrophage populations (eg. lung, peritoneal macrophages), further supporting its pervasive role in acquiring and maintaining the functional specificity and diversity of tissue macrophages. Taken together, our data suggest that BACH1 acts as a signal-dependent master regulator that directly controls key transcriptional circuits during tissue macropha…
