1. ⭐ GSE312646 TRC-051384激活热休克通路保护螺旋神经节神经元免受噪声引起的听力损失[空间转录组学]
- ✍️ 作者:未知作者
- 🏷️ 关键词:spatial、spatial transcriptomics、transcriptomics、pathway
- 📝 描述:Contributors : Jeffrey N Savas ; Seby Edassery ; Miguel RamirezSeries Type : OtherOrganism : Mus musculusNoise-induced hearing loss (NIHL) is a major public health problem caused by damage to cochlear hair cells, synapses, and spiral ganglion neurons (SGNs). However, effective treatments are completely lacking. We investigated cellular stress responses induced by loud noise in a mouse model of cochlear synaptopathy and tested whether selective activation of the dominant pathway identified could confer protection. RNA sequencing and spatial transcriptomics revealed that noise exposure elicited a robust but transient upregulation of endoplasmic reticulum chaperones and proteasome subunits in SGNs and supporting cells. To target this response, we administered TRC051384, a small-molecule activator of the heat shock transcription factor Hsf1, prior to noise exposure. TRC051384 crossed the blood–labyrinth barrier and reached the cochlea, induced heat shock protein gene expression, and restored ubiquitin–proteasome function in SGNs. Notably, TRC051384 treatment improved auditory brainstem response recovery, preserved Wave I amplitudes, and maintained ribbon synapse density. These findings establish proteotoxic stress in SGNs as a central driver of NIHL and identify HSF1 activation as a promising therapeutic strategy.

- 📝 描述:Contributors : Alex DeCasien ; Jacob Arnoff ; Elizabeth Mallot ; Sahana Kuthyar ; Sriram Chitta ; Brian Layden ; Maria Savo Sardaro ; Stanton Grey ; Lawrence Williams ; Emma Leichty ; Hyo Lee ; Won Lee ; James Curly ; Christopher Kuzawa ; Katherine AmatoSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusMultiple primate species, including humans, evolved brains that are exceptionally large relative to their body sizes. These large brains coevolved with metabolic adaptations that enhance cerebral energy supply, including increased circulating glucose levels. While the gut microbiota (GM) is known to influence host metabolism, its potential role in primate brain evolution remains unclear. To investigate this, we inoculated germ-free mice with the GMs of primate species selected to separate the effects of brain size (encephalization) from phylogenetic relatedness: humans (large-brained, Catarrhini), macaques (smaller-brained, Catarrhini), and squirrel monkeys (large-brained, Platyrrhini). We first show that differences in brain gene expression between mice inoculated with human versus macaque GMs resemble those observed between actual human and macaque brains. Comparing the effects of the different primate GMs on mouse brain gene expression further revealed that, despite greater evolutionary distance, the GMs from the two larger-brained species (humans and squirrel monkeys) similarly upregulated genes associated with energy production. Notably, human GMs specifically increased the expression of genes involved in oxidative phosphorylation, and these gene expression changes correlated with increased abundances of GM metabolic pathways related to glucose metabolism and gluconeogenesis. Human GMs also downregulated evolutionarily conserved genes implicated in neurodevelopmental disorders such as autism. Although these are findings based on a small sample of primate species and must be interpreted as preliminary, they suggest that species differences in GM composition can influence brain metabolism and raise the possibility that the GM could have played a supporting role in primate encephalization.

3. GSE312384 BACH2 调控 T 细胞谱系状态以增强 CAR T 细胞功能 [ATAC-seq]
- ✍️ 作者:未知作者
- 🏷️ 关键词:T cell、ATAC-seq
- 📝 描述:Contributors : Tien-Ching Chang ; John M Warrington ; Nathan A SinghSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensNearly all chimeric antigen receptors (CARs) signal in the absence of antigen, referred to as “tonic signaling”. Tonic signaling of CARs containing the CD28 costimulatory domain has been shown to driveT cell exhaustion; in contrast, we found that tonic signaling of 41BB-containing CARs enhances T cell function. Using a panel of CARs targeting CD22, we identified that tonic 41BB signaling activatesBACH2, a transcriptional regulator that directs stem and memory programs. Overexpression of BACH2 prevented tonic CD28-driven exhaustion but locked CAR T cells in quiescent states. To overcome this, we linked BACH2 to a degradation domain and found that tuning BACH2 expression enhanced long-term efficacy of exhaustion-prone CAR T cells targeting liquid and solid tumors. Through interrogation of CAR products, we also found an association between BACH2 activity and clinical outcomes in patients with leukemia. These data identify a central role for BACH2 in regulating CAR T cell efficacy.

4. GSE312224 小鼠耳蜗血管纹内皮细胞和周细胞群的单细胞RNA测序

- 🏷️ 关键词:RNA-seq、single-cell
- 📝 描述:Contributors : Zhiqiang Hou ; Yunpei Zhang ; Jinhui Zhang ; Pingting Wang ; Xiaorui ShiSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusThe cochlear stria vascularis (SV) maintains the endocochlear potential and relies on specialized vascular endothelial cells and pericytes. To characterize the transcriptional profiles of these vascular populations at single-cell resolution, we performed single-cell RNA sequencing (scRNA-seq) on SV tissue from reporter mice. SV was microdissected from temporal bones of 1–3 month-old Tie2-GFP (endothelial reporter) and NG2-DsRed (pericyte reporter) mice, enzymatically dissociated to obtain single-cell suspensions, and, when applicable, subjected to FACS enrichment for Tie2-GFP–positive endothelial cells or NG2-DsRed–positive pericytes. Viable cells were loaded onto the 10x Genomics Chromium platform for single-cell capture and 3′ barcoded library preparation. This dataset contains two independent batches corresponding to SV endothelial cell–enriched and pericyte-enriched preparations and enables analysis of vascular heterogeneity within the mouse stria vascularis.

- 📝 描述:Contributors : Simen F Pettersen ; Eleni Skandalou ; Jessica Furriol ; Tarig Osman ; Hans-Peter Marti ; Øystein S EikremSeries Type : OtherOrganism : Homo sapiensWe have perfomed Visium HD spatial transcriptomics on archival FFPE kidney biopsies from patients with different manifistations of nephrotic syndrome, i.e., steriod sensitive, frequent relapsing and/or steroid dependent, and focal segmental glomerulosclerosis. Using a pre-trained deep learning model from StarDist to segment nuclei, we reconstructed single-nucleus level spatial trancriptomic datasets through custom binning of subcellular capture areas. We integrated the datasets from the different patients and indentified conserved cell types. Moreover, we identified patient specific transcriptomic differences in the podocyte cell population. This article demonstrates the usefullness of this approach to future studies of pathophysilogical mechanisms in idiopathic nephrotic syndrome.

6. GSE292096 NFAT介导胰腺导管腺癌中癌相关成纤维细胞的促肿瘤炎症[小鼠VIVIT]
- ✍️ 作者:未知作者
- 🏷️ 关键词:cancer、inflammation
- 📝 描述:Contributors : Chuner Guo ; Michelle F Griffin ; Annah G Morgan ; Michael T Longaker ; Jeffrey A NortonSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusPancreatic ductal adenocarcinoma (PDAC) is characterized by a dense stroma, low immunogenicity, and resistance to therapy. Cancer-associated fibroblasts (CAFs) are key stromal cells within the tumor microenvironment (TME) that drive tumor progression. Interleukin-1 (IL-1) promotes fibrosis, pathogenic inflammation, and poor prognosis in PDAC. Using a novel single-cell multiomic approach, we investigate the IL-1 signaling axis in human and mouse models of PDAC, identifying nuclear factor of activated T cells (NFAT) transcription factors as key mediators. IL1R1+ CAFs activate an inflammatory phenotype associated with elevated NFAT motif activity and gene expression. In vivo, NFAT inhibition in a mouse model of PDAC significantly reduces tumor weight and fibrosis, supporting its pro-tumorigenic role. Our findings suggest that NFAT mediates IL-1-induced inflammation in PDAC, highlighting its potential as a therapeutic target. This study demonstrates the power of multiomic analyses to uncover therapeutic targets within the complex tumor microenvironment.

- 🏷️ 关键词:single-cell
- 📝 描述:Contributors : Yu-Tung Li ; Saki IshinoSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusPreviously, in a meta-analysis of public single-cell transcriptomes profiling various healthy and disease tissues, we demonstrated that macrophage heterogeneity in skin, as well as in other mouse tissues, could be described into 5 distinct identities (S1-5) with a defined transcriptomic fingerprint, regardless of tissue origins. We established a general identity scheme for tissue macrophages, MIKA (Macrophage Identity Kinetics Archive) as an alternative to the conventional M1/M2 scheme which shows limitations in annotating in vivo tissue macrophages. (PMID: 39720957) MIKA was recently updated to finetune identity definition, and to include more tissues and pathophysiological conditions. (PMID: 41342690) Under the current MIKA framework, tissue macrophages are classified to 6 core identities (S1-S6, common to various tissues) and/or tissue-specific macrophages. This dataset is a part of the raw data sources of the latest version of MIKA profiling single-cell transcriptomes of F4/80+MHCII-hi macrophages FACS-isolated from dorsal skin of young (9 week-old) and old (108 week-old) C57BL/6 male mice.
