Among the many drivers of tubular injury, lipid accumulation and inflammation are emerging as major contributors to kidney disease progression, but the molecular link between lipid metabolism and inflammatory signaling remains to be determined. Kidney biopsies from patients with DKD across pathologic classes were labelled for lipid droplets and analyzed by Nile Red spectroscopy. Digital spatial profiling and single-cell spatial transcriptomics were performed on samples from 14 patients representing different DKD classes. RNA scope and immunofluorescence microscopy were used for data validation and characterization. Lipid droplets (LD) were increasingly abundant in advanced stages of DKD, primarily accumulating in the proximal tubules. Single-cell spatial transcriptomics identified several genes—DUSP5, AZU1, COL9A1, HSPB1, and IGFBP7—as highly upregulated in DKD. Remarkably, IL32, which encodes a LD-associated cytokine, was highly enriched in injured proximal tubules. Immunofluorescence confirmed IL-32 localization to LDs predominantly within KIM1 positive tubules in moderate to advanced DKD. Furthermore, injured IL-32 expressing tubules were in close proximity to infiltrating neutrophils and macrophages, immune effectors of non-resolving inflammation and kidney disease progression. IL-32 is a LD-associated cytokine upregulated during tubular injury that represents a potential link between lipid dysregulation, inflammation and progression in human DKD.

- 📝 描述:Contributors : Baul Yoon ; Yifeng Xu ; Ping Zhu ; Yuji Zhang ; Xiaolei XuSeries Type : Expression profiling by high throughput sequencingOrganism : Nothobranchius furzeriAging is a major contributor to functional decline of the heart and various cardiovascular diseases. Alterations across different cardiac cell types must be tightly orchestrated during normative aging process that has begun to be mapped at the transcriptional level through single-cell RNA-sequencing. However, current rodent models are limited in their capacity to experimentally test large numbers of candidate differentially expressed genes (DEGs). As an attractive alternative, the African Turquoise Killifish (ATK) promises more efficient genetic studies of cardiac aging because it has the shortest lifespan among vertebrates. Despite its experimental advantages, single-cell transcriptomic studies on cardiac aging in ATK have not yet been conducted. Here, we generated the first scRNA-seq profiles of hearts from young and old GRZ strain ATK and demonstrated changes in cellular composition, gene expression, functional pathways, and intercellular communication during cardiac aging.

- 📝 描述:Contributors : Anna Csiszar ; Zoltan Ungvari ; Roland Patai ; Tripti Gautam ; Tamas KissSeries Type : OtherOrganism : Mus musculusChemotherapy-induced cognitive impairment (“chemobrain”) is a frequent side-effect in cancer survivors treated with paclitaxel (PTX). The mechanisms responsible for PTX-induced cognitive impairment remain obscure, and there are no effective treatments or prevention strategies. Here, we test the hypothesis that PTX induces endothelial senescence, which impairs microvascular function and contributes to the genesis of cognitive decline. We treated transgenic p16-3MR mice, which allows the detection and selective elimination of senescent cells, with PTX (5 mg/kg/day, 2 cycles; 5 days/cycle). PTX-treated and control mice were tested for spatial memory performance, neurovascular coupling (NVC) responses (whisker-stimulation-induced increases in cerebral blood flow), microvascular density, blood-brain barrier (BBB) permeability and the presence of senescent endothelial cells (by flow cytometry and single-cell transcriptomics) at 6 months post-treatment. PTX induced senescence in endothelial cells, which associated with microvascular rarefaction, NVC dysfunction, BBB disruption, neuroinflammation, and impaired performance on cognitive tasks. To establish a causal relationship between PTX-induced senescence and impaired microvascular functions, senescent cells were depleted from PTX-treated animals (at 3 months post-treatment) by genetic (ganciclovir) or pharmacological (treatment with the senolytic drug ABT263/Navitoclax) means. In PTX treated mice, both treatments effectively eliminated senescent endothelial cells, rescued endothelium-mediated NVC responses and BBB integrity, increased capillarization and improved cognitive performance. Our findings suggest that senolytic treatments can be a promising strategy for preventing chemotherapy-induced cognitive impairment.

6. ⭐ GSE292858 RNA-Seq 分析结直肠癌患者的肿瘤和匹配的正常样本。

- 🏷️ 关键词:tumor、cancer、RNA-seq
- 📝 描述:Contributors : Gloryn L Chia ; Oleg V Grinchuk ; Malini Rethnam ; Yi Ren ; Sharmistha KunduSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensTumour cells often downregulate human leukocyte antigen (HLA) class I to evade cytotoxic T lymphocyte (CTL) immunity. Although natural killer (NK) cells target MHC-I-deficient cells, many cancers bypass NK cell-mediated killing through additional immune evasion strategies. Using CRISPR-Cas9 screening, GPC2, a cell surface protein, was identified as a key suppressor of NK cell activity against HLAnull cancer cells. GPC2 is upregulated in several cancers, correlating with poor patient outcomes. In colorectal cancer, GPC2 was found to be inversely correlated with HLA class 1 expression.

7. ⭐ GSE262633 组蛋白变体 H2A.J 是人类滋养层发育中的关键表观遗传调控因子 [scRNA-seq]
- ✍️ 作者:未知作者
- 🏷️ 关键词:scRNA、epigenetic、histone
- 📝 描述:Contributors : Tyler Jensen ; Liangwen Zhong ; Andrew Xiao ; Berna Sozen ; Zongliang JiangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensThe preimplantation development in eutherian mammals is diverse. However, ethical and technical constraints significantly limit our understanding of the molecular and biochemical pathways governing human development. In this study, we discovered an unexpected, species-specific epigenetic pathway regulated by H2A.J, a largely uncharacterized histone variant in preimplantation development using human Blastoid models, IVF bovine embryos, and in vitro human stem cell models. We discovered that H2A.J is expressed in human and bovine placentas, contrasting with its absence in mice, and that H2A.J is essential for trophoblast expansion and viability in human and bovine. Our findings also revealed that H2A.J is enriched at promoters and introns of genes and interacts with RNA Polymerase I and II and pro-elongation factors, thereby regulating RNA Polymerase elongation and trophoblast maintenance in human embryo development. This study sheds light on a novel chromatin factor crucial for proper development in humans and large mammals, offering insights into the evolution of preimplantation development in eutherians. Our research provides valuable insights into evolutionarily divergent epigenetic mechanisms and biological functions in trophoblast lineage maintenance and transcriptional regulation, laying the groundwork for future investigations into the essential but understudied process of human placentation.

- 📝 描述:Contributor : Lorenzana-Carrillo Maria AreliSeries Type : Genome binding/occupancy profiling by high throughput sequencing ; Expression profiling by high throughput sequencingOrganism : Homo sapiens ; Mus musculusThis study aims to investigate the role of ZNF281 in cardiomyocyte function and tumor biology by integrating RNA-seq and ChIP-seq datasets. Using a C57BL/6 mouse model, we isolated cardiomyocytes from ZNF281 overexpression (OE) and knockdown (Kd) mice, along with their respective controls, to analyze transcriptomic changes and ZNF281 genome-wide binding patterns. Additionally, we included tumor samples from nude mice, specifically A549 ZNF281 knockout (KO) tumors and parental A549 tumors, to explore the differential regulation and binding patterns of ZNF281 between cardiac tissue and tumors. RNA-seq was performed to identify differentially expressed genes regulated by ZNF281 in both contexts, while ChIP-seq was conducted to map ZNF281 DNA-binding sites and its role in transcriptional regulation. This study will provide insights into the context-dependent functions of ZNF281 in the heart and tumors, enhancing our understanding of its role in cardiac biology and cancer progression.

10. GSE298644:BRN2诱导的ATR/STAT3通路或Shieldin 2亚克隆扩增介导三阴性乳腺癌对新辅助他拉唑帕尼的耐药性
- ✍️ 作者:未知作者
- 🏷️ 关键词:cancer、resistance
- 📝 描述:Contributors : Noor M Abdulkareem ; Yan Jiang ; Yuan Qi ; Xuan Liu ; Xiaomei Zhang ; Shirong Cai ; Jiansu Shao ; Sabrina Jeter-Jones ; Amanda L Rinkenbaugh ; Chun-Chun Cheng ; Faiza Hancock ; Jill Schwartz ; Jennifer K Litton ; Jeffrey T Chang ; Helen Piwnica-WormsSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensIntrinsic and acquired resistance to poly(ADP-ribose) polymerase (PARP) inhibitors (PARPi) remains a major barrier in treating homologous recombination (HR) repair-deficient tumors, including those with germline or somatic BRCA1/2 mutations. Although PARPi are FDA approved for adjuvant treatment of locally advanced or metastatic breast cancer in patients with germline BRCA1/2 mutations, emerging data support their use as monotherapy in the neoadjuvant setting. Promising safety profiles of newer-generation PARPi further support this potential. However, resistance mechanisms specific to the neoadjuvant setting are poorly understood. To address this gap, we leveraged resources from a phase II neoadjuvant clinical trial (NCT03499353), analyzing tumors from patients with germline BRCA1/2 mutant breast tumors before and after six months of talazoparib monotherapy. Whole-transcriptome analyses were performed on these samples. Additionally, we established orthotopic patient-derived xenograft models from a subset of the patient tumors and conducted whole-exome and whole-transcriptome analysis. This integrative approach revealed both known and novel PARPi resistance mechanisms. In one case, overexpression of BRN2, encoding a transcription factor that plays a critical role in neurogenesis, led to activation of ATR/RAD51 and STAT3 pathways, restoring homologous recombination (HR) repair. BRN2-driven resistance could be reversed with ATR and STAT3 inhibitors, resensitizing cells to talazoparib. In another, an HR repair proficient tumor subclone lacking Shieldin 2 expression expanded during treatment and accounted for intrinsic resistance. Our findings highlight the need to determine intrinsic and anticipate acquired resistance pathways in treatment-naïve tumors and support combining PARPi with targeted agents to improve outcomes in the neoadjuvant setting.
