1.GSE317680 Single Cell and Spatial Transcriptomics Identify Novel Immune-Stromal Interactions in Cardiac Allograft Vasculopathy

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:immune、cardiac、spatial、spatial transcriptomics、transcriptomics
  • 📝 描述:Contributors : Li Daniel Y ; Gu Wenduo ; Cheng Paul CSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensCardiac allograft vasculopathy (CAV) is the leading cause of mortality in heart transplant recipients. Despite the prevalence of CAV, there are no targeted therapeutic options to prevent or reverse disease progression, and patients ultimately require retransplant. CAV is defined by progressive neointimal hyperplasia in donor heart coronary arteries, leading to luminal obliteration and ultimately allograft failure or sudden cardiac death. Although immune and stromal cell interactions are believed to play a key role in CAV pathogenesis, the specific cellular players and molecular signals driving disease remain undefined. In this study, we leverage single-cell RNA sequencing and spatial transcriptomics of human coronary arteries to transcriptionally characterize CAV and define the neointimal microenvironment. We compare arteries with CAV to atherosclerotic coronary artery disease and non-disease controls to identify a unique CAV transcriptional signature.

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:T cell、macrophage、glioma、regex:immuno(logy|therapy|suppression)
  • 📝 描述:Contributors : Xinnan Wang ; Menghan Li ; Zehui DuSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensWe generated bulk RNA sequencing (RNA-seq) data from human glioma surgical resections treated ex vivo with a MIRO1-binding compound (MR3) or vehicle control. Fresh tumor specimens were processed and cultured under controlled conditions prior to RNA extraction and high-throughput transcriptomic profiling to characterize treatment-associated gene expression changes within the tumor microenvironment (TME). The dataset captures global transcriptional programs from tumor tissue, reflecting contributions from malignant cells as well as stromal and immune components present in the resections. These data enable analysis of MIRO1-dependent transcriptional regulation in human glioma and facilitate cross-species integration with murine single-nucleus RNA-seq datasets. This resource supports investigation of mitochondrial-associated transcriptional programs and their impact on immune microenvironment remodeling in human glioma.

4.GSE320101 研究发现,靶向 USP14 通过重编程结肠癌肿瘤相关巨噬细胞来增强免疫治疗反应。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、cancer、regex:immuno(logy|therapy|suppression)
  • 📝 描述:Series Type : Expression profiling by high throughput sequencingOrganism : Mus musculusCombining immunotherapy with other treatments improves survival in colorectal cancer, yet some patients remain unresponsive. Tumor-associated macrophages (TAMs) are a key immune cell population driving this immunotherapy resistance and fostering an immunosuppressive microenvironment. To overcome this, we screened a deubiquitinating enzyme (DUB) library targeting TAMs and identified USP14 as specifically upregulated in TAMs. Inhibiting USP14 reversed their pro-tumor functions, promoted M1 polarization, enhanced tumor cell killing, and activated effector T cells. USP14 inhibition also increased PD-L1 expression on tumor cells, alleviating T-cell suppression. In vivo, combining a USP14 inhibitor with an anti-PD-1 antibody synergistically enhanced immunotherapy efficacy, suppressed tumor progression, and improved survival in a mouse colon cancer model. Thus, USP14 is a promising target to overcome immunotherapy resistance in colorectal cancer.

5.GSE277728 GSK3β介导的SOX4磷酸化及其与STAT6的相互作用调节MTHFD2表达、NADPH产生、癌症干细胞特性和肝细胞癌预后[ChIP-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、carcinoma、ChIP-seq
  • 📝 描述:Contributors : Chia-Lung Tsai ; Ming-Chin Yu ; Chi-Neu TsaiSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensSOX4 is associated with poor prognosis in various cancers, including hepatocellular carcinoma (HCC). SOX4 plays a crucial role in angiogenesis, cellular differentiation, and cell growth through interactions with transcription factors in response to stimuli. Despite its overexpression and link to poor prognosis, SOX4 remains an undruggable target. Therefore, targeting its interacting or regulatory proteins might disclose a therapeutic strategy in HCC. Our aim was to elucidate SOX4 regulation and interactions in HCC cells to provide further insights into its role in tumorigenesis. GSK3β phosphorylated SOX4 at serine residues 379, 383, 387, 391, and 395, as revealed by in vitro kinase assays, which stabilized SOX4 protein. Interactions between SOX4, STAT6, and GSK3β in HCC cells were confirmed by co-immunoprecipitation, immunofluorescence, and proximal-ligation assay. Knockout SOX4 or inhibition of STAT6 repressed cell growth, sphere formation, and NADPH production through modulating MTHFD2 expression, which in turn repressed expression of PD-L1 in HCC cells. The significant elevated NADPH was found in SOX4high HCC tumor specimen as compared with the SOX4low tumors. Positive correlations of GSK3β & SOX4, STAT6 & SOX4, and SOX4 & MTHFD2 proteins were observed in liver cancer specimens through western blot analysis. Furthermore, tumor lesion with elevated of SOX4, MTHFD2, or both SOX4 and MTHFD2 transcripts tend to have poor prognosis in patients with HCC using TCGA-LIHC database. Treatment with inhibitors targeting STAT6 or MTHFD2 reduced cell proliferation in vitro and attenuated tumor growth in an HCC patient-derived xenograft (PDX) mice model in vivo. The GSK3β/SOX4/STAT6/MTHFD2 regulatory axis played a critical role in modulating NADPH production and maintaining cancer stemness, associated with poor prognosis in HCC that might be a potential therapeutic target.

7.GSE316452 西方饮食和M​​C4R基因敲除诱导的MASH模型小鼠肠-肝轴微生物组和代谢组的跨器官多组学分析

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:metabolome、gut、regex:gut(-?microbiome)?
  • 📝 描述:Contributors : Mitsuharu Matsumoto ; Osamu Miura ; Takeo Moriya ; Hitomi Ogino ; Megumi Hirayama ; Akira Mitsui ; Takaharu Hirayama ; Yukihiko Ebisuno ; Manami Kaneko ; Yoshinori Satomi ; Yasunori NioSeries Type : OtherOrganism : Mus musculusBackground: Western diet (WD) fed Melanocortin 4 receptor-knockout (MC4R-KO) mice develop a phenotype resembling human metabolic dysfunction-associated steatohepatitis (MASH). Despite its clinical relevance, the role of the gut–liver axis in MASH pathogenesis remains unclear. This study investigated the gut-liver axis through microbiomic and metabolomic analyses of WD-fed MC4R-KO mice, and examined their association with MASH pathology. Methods: We performed an integrated microbiome and metabolome analysis of the liver, small intestinal contents, large intestinal contents, and plasma of wild-type (WT) and MC4R-KO mice fed either a normal diet or WD. Markers of hepatic inflammation, fibrosis, and steatosis measured in this study were used to assess MASH severity and to correlate microbiome and metabolite alterations. Results: WD-fed MC4R-KO mice exhibited significant hepatic steatosis, inflammation, and fibrosis. The abundance of certain microbiota, including Muribaculaceae and Allobaculum, negatively correlated with MASH severity, whereas increased levels of Desulfovibrionaceae and Bacteroides positively correlated with hepatic lipid accumulation, steatosis, and inflammation. Metabolomic profiling revealed increased triglyceride and diglyceride levels in the liver and a concomitant decrease in free fatty acids and monoglycerides in the intestines. Additionally, plasma taurine-conjugated bile acids were elevated in WD-fed MC4R-KO mice, which correlated with the reduced hepatic transport of bile salts from pathway enrichment analysis. These findings highlight substantial alterations in the gut microbiota and lipid and bile acid metabolism, indicating a mechanistic dysregulation of the gut–liver axis that may contribute to MASH progression. Conclusions: The observed gut microbial and metabolic alterations, particularly bile acid and lipid metabolism dysregulation, offer insights into potential therapeutic targets aimed at modulating the gut–liver axis to treat or prevent MASH.

9. GSE322498 CTNNB1 突变介导非小细胞肺癌对 EGFR 靶向治疗的耐药性

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、resistance
  • 📝 描述:Contributors : Haura Eric ; Majumder AnurimaSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensCTNNB1 mutations, which cause activation of Wnt target genes, are found to co-occur in EGFR-mutant lung cancer. We hypothesize that these mutations enhance stability of β-catenin protein and upregulate Wnt signaling, thereby promoting resistance to targeted therapy. CTNNB1 mutation spectrum was analyzed in non-small cell lung cancer patients in The Cancer Genome Atlas (TCGA) and Moffitt Cancer Center patient databases to identify prevalent CTNNB1 mutations as well as frequency of co-occurring mutations. EGFR-mutant HCC827 cells were engineered to stably express most frequent CTNNB1 mutations to determine their ability to drive resistance to EGFR TKI. Western blotting and RNA sequencing were performed to assess the molecular differences between cells expressing wild-type and erlotinib resistant CTNNB1T41A. A viability screen was also performed in which these cells were treated with either with β-catenin siRNA or a panel of drugs with known targets, in combination with erlotinib, to identify new vulnerabilities in CTNNB1T41A cells. Our analysis shows that EGFR mutations co-occur in ~45% of CTNNB1 mutant patients. We show that CTNNB1 mutations cause stabilization and higher accumulation of active β-catenin but vary in their ability to cause erlotinib resistance, with T41A, S37F, S45C and D32H mutants being resistance inducers. Of the mutations tested, cells expressing CTNNB1T41A demonstrated the strongest resistance to erlotinib. Transcriptomics data reveals higher levels of β-catenin regulated proteins (axin2, TCF7 and survivin), EMT markers (vimentin and N-cadherin), and receptors/ligands of the FGFR signaling pathway, in HCC827 CTNNB1T41A cells when compared to CTNNB1WT. Pathway analysis of genes differentially expressed between the WT and T41A mutant cells reveal Wnt pathway to be the top upregulated pathway in the CTNNB1 mutant cells. CTNNB1T41A cells also showed sustained ERK, AKT, GSK3β and S6 signaling, and lower PARP cleavage compared to wild type. Combining erlotinib with PI3K/mTOR/MEK inhibitors or CTNNB1 knockdown can partially reverses erlotinib resistance in HCC827 CTNNB1T41A cells. Our data suggests that CTNNB1 may be an important co-occurring alteration in developing resistance to targeted EGFR therapy. We show that the ability of a CTNNB1 mutation to drive resistance to EGFR TKI relates with the activation of CTNN…

10. GSE314155 BRD9 读取乳酸诱导的 H3K18 乳酸化驱动肝细胞癌中的致癌染色质重塑

  • ✍️ 作者:未知作者

  • 📝 描述:Contributors : Enwei Wei ; Donglei Ji ; Yanjie Jia ; Ze Sun ; Chunfeng Gao ; Caroline Zeng ; Chunyu Wang ; Miaomiao Yu ; Guanglei Shang ; Linying Xie ; Wenju Zhang ; Yameng Li ; Yingying Liang ; Bai Ji ; Yanzhu Yue ; Yahui Liu ; Ming-Ming Zhou ; Lei ZengSeries Type : Expression profiling by high throughput sequencing ; Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensHistone lactylation bridges glycolytic metabolism to oncogenic transcription, but its mechanistic readers remain poorly defined. Here, we identify bromodomain-containing protein 9 (BRD9) as a lactyl-lysine reader that links lactate-driven H3K18 lactylation (H3K18la) to chromatin remodeling in hepatocellular carcinoma (HCC). Clinically, elevated H3K18la levels correlate with poor HCC prognosis. Structural (NMR) and biophysical analyses demonstrate BRD9’s bromodomain engages H3K18la through its acetyl-lysine pocket with weak, transient affinity, distinct from stable H3K18ac binding, enabling lactate-dependent chromatin interactions. Multi-omics profiling reveals H3K18la recruits BRD9 and the non-canonical BRG1-associated factor (ncBAF) complex to active enhancers and promoters, promoting chromatin accessibility and oncogenic transcription (SPARC, TMEM64, ANGEL1, SCARB1). Glycolytic inhibition or BRD9 targeting displaces BRD9 from chromatin, suppresses oncogenes, and impairs HCC proliferation. p300 or HDAC inhibition attenuates H3K18la-driven oncogenic transcription and tumor viability. Our findings establish BRD9 as a metabolic-epigenetic mediator that translates glycolytic flux into chromatin remodeling, offering actionable therapeutic targets for HCC.

3. Scientists discover the switch that revives exhausted cancer-fighting T cells

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer
  • 📝 描述:Scientists have uncovered new genetic rules that determine whether the immune system’s “killer” T cells remain powerful long-term defenders or become worn out and ineffective. By building a detailed genetic atlas of CD8 T cell states, researchers identified key molecular switches that push these cells toward either resilience or exhaustion. Remarkably, disabling just two previously unknown genes restored the tumor-killing power of exhausted T cells while preserving their ability to provide lasting immune protection.
