1.GSE318315 MERTK抑制剂与免疫调节剂环磷酰胺协同作用,诱导三阴性乳腺癌中CXCL9阳性单核细胞-巨噬细胞的程序化和持久的抗肿瘤免疫。

  • 📝 描述:Contributors : Alex Smith ; Jeffrey RosenSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusTriple negative breast cancer (TNBC) has high rates of recurrence despite chemotherapy and immune checkpoint blockade (ICB). Tumor associated macrophages (TAMs) can either suppress or support anti-tumor immunity, but the mechanisms governing these states and their therapeutic targeting remain unclear. Here, by integrating public single-cell datasets with TNBC patient cohorts, we identify a prognostic myeloid signature defined by CXCL9-high and C1Q-low TAM programs that is associated with improved survival and increased lymphocyte activation pathways. Using immunocompetent p53-null syngeneic TNBC models spanning basal-like (2153L) and claudin-low (T12) subtypes, we show that immunomodulatory cyclophosphamide (CTX) reprograms hematopoiesis toward the monocytic lineage and induces an interferon conditioned tumor microenvironment that supports CXCL9-positive monocyte-derived macrophages in basal-like disease. Combining CTX with the next generation MERTK-selective inhibitor ULC2371 (MRX-2843) drives complete tumor remissions in both models; however, durable long-term responses occur selectively in the basal-like subtype. Responding tumors exhibit expansion of antigen-presenting CXCL9-positive monocyte-derived macrophages and a reduction of C1q-positive phagocytic TAMs. Mechanistically, MERTK inhibition relieves MAPK and SOCS1 mediated restraint of interferon signaling, driving a positive feedback loop involving IRF7, STAT1, and IRF1 that promotes sustained CXCL9 induction. Functionally, tumor control requires CXCL9-CXCR3 dependent CD4 T cell recruitment, accumulation of stem-like memory CD4 T cells, and germinal center-like immune organization in tumor draining lymph nodes. PD-1 blockade further enhances response durability, preventing recurrence in most treated basal-like tumors.Together, these findings define an interferon-licensed, MERTK-regulated myeloid checkpoint that can be therapeutically targeted to convert immunosuppressive TNBC microenvironments into durable adaptive immunity, supporting clinical translation of CTX and MRX-2843 based combination therapies in basal-like TNBC.

  • 📝 描述:Contributors : Yan Wang ; Yingru ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusThe high prevalence of depressive disorders in individuals with cancer and their contribution to tumour progression is a topic that is gradually gaining attention. Recent evidence has shown that there are prominent connections between immune gene variants and mood disorders. The ho_x0002_meostasis of the tumour immune microenvironment (TIME) and the infiltration and activation of immune cells play a very important role in the antitumour effect. In this study, we established a compound mouse model with chronic unpredictable mild stress (CUMS) and orthotopic colorectal cancer to simulate colorectal cancer (CRC) patients with depression. Using 10✕Genomics single_x0002_cell transcriptome sequencing technology, we profiled nearly 30,000 cells from tumour samples of 8 mice from the control and CUMS groups, revealed that immune cells in tumours under a chronic stress state trend toward a more immunosuppressive and exhaustive status, and described the crosstalk between the overall inflammatory environment and immunosuppressive landscape to provide mechanistic information or efficacious strategies for immune-oncology treatments in CRC with depressive disorders.

  • 📝 描述:Contributors : Xinnan Wang ; Menghan Li ; Brandon Bergsneider ; Zehui DuSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusWe generated single-nucleus RNA sequencing (snRNA-seq) data from murine gliomas treated in vivo with a MIRO1-binding compound or vehicle control. Tumors were dissociated and processed for nucleus isolation followed by high-throughput transcriptomic profiling to characterize cell-type-specific gene expression programs within the tumor microenvironment (TME). The dataset captures malignant cells and diverse stromal and immune populations, including macrophages, microglia, and T cells, enabling analysis of treatment-associated transcriptional changes at single-cell resolution. These data provide a resource for investigating mitochondrial-associated transcriptional regulation and immune microenvironment remodeling in murine glioma.

  • 📝 描述:Contributors : Julie Y Zhou ; Ryan J Musich ; Amalu Job ; Thaddeus S StappenbeckSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusDeveloping new tools for studying the intestinal epithelium is essential for addressing unan-swered questions in development, physiology, and disease pathology. Primary intestinal epitheli-al stem cell (ISC) cultures are an invaluable in vitro model system. However, their cultivation re-mains technically demanding and costly, limiting their accessibility and use. Though commonly utilized, most extant intestinal epithelial cell lines were derived from colon adenomas from vari-ous animals, are largely uncharacterized, and possess a plethora of genetic abnormalities, thus restricting rigor, reproducibility, and physiological relevance. Here we derived immortalized intestinal epithelial cell lines (iIECs) from six jejunal and six colonic stem cell-enriched spheroid cultures from wild type C57BL/6 mice. We transduced ISCs with a lentiviral vector encoding the SV40 large T antigen, and subsequently selected lines through adaptation to growth on plastic. Additionally, we weaned these lines off conditioned medium including the growth factors Wnt3a, Rspo3, and Noggin. We found that iIECs have growth characteristics similar to conventional plastic adapted cell lines. While we observed transcriptional signatures of epithelial-mesenchymal transition (EMT), these cells still exhibited epithelial characteristics including ex-pression of junctional proteins, mounted an innate immune response to viral infection, and se-creted cytokines in response to LPS stimulation. We further demonstrated the utility of iIECs through transient and stable genetic manipulation. iIECs occupy an important experimental niche through offering a scalable, practical, and physiologically relevant model system that can func-tion as a discovery platform before transitioning to primary spheroid cultures and/or animal models. We propose that they will be a valuable tool for advancing understanding of intestinal epithe-lial biology.

  • 📝 描述:Contributors : Laura Braud ; Manuel Bernabe ; Julien Vernerey ; Dmitri Churikov ; Manon Richaud ; Antonio M Miranda ; Liam Mc Allan ; Christophe Lachaud ; Jesus Gil ; William Scott ; Vincent GeliSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusObesity is linked to limited adipose tissue (AT) remodeling capacity, leading to hypertrophic adipocytes, senescence, and inflammation. We used a mouse model expressing mTert, or its catalytically inactive form mTertCi, from the Cdkn1a locus to investigate the role of mTERT in obesity-induced metabolic disorders in mice on a high-fat-diet (HFD). We found that mTERT expression attenuates p21 expression, telomere attrition, senescence, and inflammation in the AT of HFD-induced obese mice, thereby reducing associated metabolic disorders. In vivo and in vitro data reveal that mTERT promotes differentiation of adipose stem and progenitor cells into adipocytes in obese mice. Strikingly, single nucleus RNA-seq data show that both mTERT and mTERTCi remodels the landscape of macrophages in AT of obese mice thereby reducing the immune response. These results emphasize involvement of the canonical and non-canonical mTERT functions in ameliorating metabolic disorders and suggest conditional TERT expression as a potential therapeutic option for obesity.

8.GSE310166 组蛋白串扰介导的互斥 H3K79 甲基化区域的建立 [ChIP-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:ChIP-seq、methylation、histone
  • 📝 描述:Contributors : Na Hyun Park ; Hwa-Ryeon Kim ; Jae-Seok Roe ; TaeSoo KimSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Saccharomyces cerevisiaeHistone H3 lysine 79 (H3K79) methylation plays critical roles in various cellular processes, including development and DNA repair, potentially through modulation of chromatin structure and gene expression. Despite its importance, the genome-wide distribution patterns, mechanisms of establishment, and functional distinctions among its mono-, di-, and tri-methylated forms (H3K79me1, me2, and me3) remain largely unclear. Here, we generated genome-wide maps of H3K79me1, H3K79me2, and H3K79me3 using ChIP-seq and found that each methylation state is predominantly associated with a unique subset of genes, which we term state-specific H3K79 methylation zones. These zones are mutually exclusive and are stably maintained even during global transcriptional reprogramming. We further demonstrate that H2B ubiquitination mediated by the Rad6-Bre1 complex is essential for the integrity of these methylation zones. Specifically, deletion of RAD6 leads to the complete loss of the H3K79me3 zone and its conversion into an H3K79me1-enriched region. Interestingly, the H3K79me1 zone is also significantly diminished upon RAD6 deletion, indicating that H2B ubiquitination supports both the maintenance and establishment of specific methylation zones. Similar disruption of the H3K79me1 landscape is observed upon loss of H4K16 acetylation. Functionally, H3K79me1 and H3K79me3 appear to have opposing roles in transcriptional regulation as loss of H3K79 methyltransferase Dot1 results in transcriptional activation of genes within the H3K79me1 zone and repression of genes within the H3K79me3 zone. Together, our findings reveal that distinct H3K79 methylation states define specific and functionally divergent chromatin domains, whose establishment and maintenance depend on trans-histone crosstalk and contribute to opposing transcriptional outputs.

10. GSE319956 FOXM1在肺癌中普遍存在,可通过T细胞受体工程进行靶向治疗。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、T cell
  • 📝 描述:Contributors : Minying Zhang ; Emily Bontekoe ; Peixin Jiang ; Alexandre ReubenSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensWe identified epitopes derived from FOXM1 which were immunogenic on HLA-A02:01, HLA-A24:02, and HLA-A*23:01, endogenously-processed and presented, and resulted in T cell activation and cytotoxic T cell responses. Following the generation of TCR-T cells, sensitivity and specificity were confirmed by peptide dose-response and X-scan, respectively. Most importantly, adoptive transfer of TCR engineered T cells led to a significant reduction in tumor growth, as well as significantly prolonged survival in NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) tumor-bearing murine model. Our studies confirm the immunogenicity of FOXM1 and feasibility of targeting this antigen using TCR-engineering.

  • 📝 描述:As deep-sea waters warm, scientists expected trouble for the microbes that help keep ocean chemistry in balance. Instead, researchers found that Nitrosopumilus maritimus can adapt to warmer, iron-limited conditions by using iron more efficiently. Because these microbes control key nitrogen reactions that support marine life, their adaptability could help sustain ocean productivity. In a warming world, they may play an even bigger role in shaping marine nutrient cycles.
