1. ⭐ GSE310042 A2780 模型的全面转录组和表观基因组分析揭示了顺铂、紫杉醇和双重耐药性的独特程序 [RNA-seq]

- 📝 描述:Contributors : Won-Young Choi ; Rachel Perkins ; Wenjing ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensOvarian cancer is the most lethal gynecologic cancer, largely because most patients eventually relapse after initially responding to platinum- and taxane-based chemotherapy. To understand how cancer cells adapt to these drugs, we generated cisplatin-resistant (CpR), paclitaxel-resistant (TxR), and dual-resistant (TxCpR) derivatives from the parental A2780 cell line and profiled their transcriptomes and chromatin landscapes using RNA-seq and ATAC-seq. The three resistant lines displayed distinct cellular morphologies, gene expression profiles, and chromatin accessibility patterns. Notably, the dual-resistant state was not simply a combination of the cisplatin- and paclitaxel-resistant states but instead represented a unique regulatory configuration. Integrative analysis of RNA-seq and ATAC-seq identified potential regulators associated with specific drug-resistance of A2780. Furthermore, we suggested resistance-specific distal regulatory regions highly related with transcription factors either directly or indirectly involved in cancer progression, cell plasticity and chemotherapy resistance. Our paired RNA-seq and ATAC-seq datasets provide valuable and comprehensive resources for exploring how enhancer–transcription factor interactions drive chemotherapy resistance and for identifying new therapeutic targets in ovarian cancer.

2. ⭐ GSE313244 子宫平滑肌肉瘤的多维单细胞转录组分析鉴定出具有不同治疗脆弱性的分子亚型 [空间转录组学]
- ✍️ 作者:未知作者
- 🏷️ 关键词:single-cell、spatial、spatial transcriptomics、transcriptomics
- 📝 描述:Contributors : Maria Korah ; James Agolia ; Daniel DelittoSeries Type : OtherOrganism : Homo sapiensUterine leiomyosarcoma (ULMS) is an orphan disease that frequently recurs and metastasizes, with patients undergoing multiple lines of chemotherapy due to lack of effective therapeutic targets. To address this gap, we used single-cell RNA sequencing and spatial transcriptomic analysis to comprehensively profile ULMS. We uncovered eight subtypes of tumor cells, including stem cell-like hormone receptor-positive cells, tumor cells with mesenchyme-like features, ischemic tumor cells defined by a MYC program, and inflammatory tumor cells with active interferon signaling. The spatial correlates of these tumor cell subtypes demonstrated unique localization patterns. By correlating these signatures to bulk RNA sequencing data, we demonstrate the scalability of these findings to clinical outcomes. Finally, using the single-cell integration and drug response prediction algorithm, we derive previously undescribed drug predictions targeting specific tumor subtypes that may be more efficacious than existing adjuvant regimens. Our findings highlight new individualized and multifaceted therapeutic avenues to treat ULMS.

4. ⭐ GSE271370 空间转录组学揭示致命性 COVID-19 患者肺部的原位细胞和分子特征
- ✍️ 作者:未知作者
- 🏷️ 关键词:spatial、spatial transcriptomics、transcriptomics
- 📝 描述:Contributors : Carlos A Garcia-Prieto ; Eva Musulen ; Veronica Davalos ; Manel EstellerSeries Type : OtherOrganism : Homo sapiensSevere Coronavirus disease 2019 (COVID-19) induces heterogeneous and progressive diffuse alveolar damage (DAD) highly disrupting lung tissue architecture and homeostasis, hampering disease management leading to fatal outcomes. Characterizing DAD pathophysiology across disease progression is of ultimate importance to better understand the molecular and cellular features driving different DAD patterns and to optimize treatment strategies. To contextualize the interplay between cell types and assess their distribution, spatial transcriptomics (ST) techniques have emerged, allowing unprecedented resolution to investigate spatial architecture of tissues. To this end, post-mortem lung tissue provides valuable insights into cellular composition and their spatial relationships at the time of death. Here, we have leveraged VisumST technology in post-mortem COVID-19 induced acute and proliferative DAD lungs including control samples with normal morphological appearance, to unravel the immunopathological mechanisms underlying DAD, providing novel insights into cellular and molecular communication events driving DAD progression in fatal COVID-19. We report a progressive loss of endothelial cell types, pneumocytes type I and natural killer cells coupled with a continuous increase of myeloid and stromal cells, mostly peribronchial fibroblasts, over disease progression. Spatial organization analysis identified variable cellular compartments, ranging from major compartments defined by cell type lineages in control lungs to increased and more specific compartmentalization including immune-specific clusters across DAD spectrum. Importantly, spatially informed ligand-receptor interaction (LRI) analysis revealed an intercellular communication signature defining COVID-19 induced DAD lungs. Transcription factor (TF) activity enrichment analysis identified TGF-B pathway as DAD driver, highlighting SMAD3 and SMAD7 TFs activity role during lung fibrosis. Integration of deregulated LRIs and TFs activity allowed us to propose a downstream intracellular signaling pathway in peribronchial fibroblasts, suggesting potential novel therapeutic targets. Finally, spatio-temporal trajectories analysis provided insights into the alveolar epithelium regeneration program, characterizing markers of pneumocytes type II differentiation towards pneumocytes type I.

6. GSE342942 口服递送载有R-spondin1的小细胞外囊泡可激活WNT信号通路,加速肠道损伤修复并逆转衰老
- ✍️ 作者:未知作者
- 🏷️ 关键词:pathway、regex:intestin(e|al)
- 📝 描述:Contributors : Shixiang Wang ; Lingyan YangSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusThe intestine plays a crucial role in regulating metabolism and immunity, with functional decline occurring during injury and ageing. Stimulating the neogenesis of intestinal stem cells (ISCs) by activating the WNT/β-catenin signalling pathway represents a promising approach for intestinal tissue regeneration and injury repair. However, effective oral delivery of functional WNT signalling agonists to the gut remains challenging. Herein, we report a potent WNT/β-catenin signalling-inducing small extracellular vesicles (sEV) that can be administered orally and present remarkable therapeutic efficacy. We demonstrate that active R-spondin1 (RSPO1) protein can be loaded onto the surface of sEV via heparan sulfate proteoglycans. Notably, sEV-delivered RSPO1 (evRSPO1) effectively induces WNT/β-catenin signalling-inducing activity, enhances ISCs proliferation, and supports intestinal organoid growth in vitro. Importantly, oral administration of evRSPO1 activates the WNT/β-catenin signalling pathway in the cryptic stem cell niche, thereby accelerating tissue repair and regeneration in a radiation-induced intestinal injury model. Furthermore, evRSPO1 treatment induces ISCs proliferation and reverses the intestinal senescence phenotype in aged mice. Collectively, this study establishes evRSPO1 as a potential first-in-class, orally deliverable therapeutic that overcomes biological barriers to activate ISCs, enabling efficient intestinal tissue repair and rejuvenation.

9. GSE338923 STK11缺陷型和亲代Lacun3小鼠肺腺癌细胞的批量RNA测序
- ✍️ 作者:未知作者
- 🏷️ 关键词:sequencing
- 📝 描述:Contributors : Daniel Ajona ; Ruben PioSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusSTK11 mutations are associated with primary resistance to immune checkpoint inhibitors in lung adenocarcinoma, but the tumor cell-intrinsic mechanisms underlying this phenotype remain incompletely understood. To investigate transcriptional changes induced by STK11 loss independently of the tumor microenvironment, bulk RNA sequencing was performed on parental Lacun3 murine lung adenocarcinoma cells and CRISPR-generated Stk11-deficient Lacun3 cells cultured in vitro. Differential gene expression analysis identified increased expression of several mediators associated with complement activation and neutrophil extracellular trap (NET) formation, supporting a tumor cell-intrinsic transcriptional program that promotes a pro-NETotic tumor microenvironment.
