1. ⭐ GSE342215 单细胞空间转录组学揭示 Prph2C213Y 小鼠外节破坏后 RPE 和 Muller 胶质细胞向感光细胞的信号通路重连

Using a heterozygous Prph2C213Y/+ mouse model generated by CRISPR/Cas9, we characterized age-related retinal pathology and responses of retinal pigment epithelium (RPE) and Muller glia. Independent age- and sex-matched cohorts were examined at 1, 3, and 6 months by electroretinography, optical coherence tomography, and fundus autofluorescence. Mutant mice showed rod dysfunction from 1 month, RPE dysfunction from 3 months, and cone dysfunction by 6 months, accompanied by progressive outer retinal thinning and hyperautofluorescent deposits. Histological and ultrastructural analyses revealed OS disorganization, shortened RPE microvilli, RPE monolayer remodeling, increased RPE autofluorescence, and reactive Muller gliosis. Single-cell spatial transcriptomics of wild-type and mutant retinas at 6 months resolved nine cell populations and identified RPE cells and Muller glia as prominently perturbed non-photoreceptor populations. RPE cells showed an epithelial-mesenchymal transition-related remodeling state linked to a candidate Nfib-Fstl1 module, whereas Muller glia showed activation of activator protein 1 (AP-1) regulons, including Fos, Fosl2, and Junb, with predicted targets Osmr, A2m, and Stat3. Cell-cell communication analyses indicated coordinated changes in neuroprotective, inflammatory, and matrix-related signaling from RPE cells and Muller glia toward photoreceptors. These findings indicate that PRPH2-associated retinal dystrophy is a multicellular process in which OS disruption drives coordinated RPE and Muller glial remodeling with potentially protective or pro-degenerative effects, and nominate the RPE Nfib-Fstl1 program, Muller glial AP-1 responses with predicted STAT3 involvement, and support-cell-derived growth factor signaling as candidate mutation-independent therapeutic targets.

Expression of CM is required for leukemia initiation. Patients with inv(16) at diagnosis invariably have the rearrangement at relapse, leading to the assumption that CM is also required after leukemic transformation. However, a role for CM in leukemia maintenance has yet to be shown experimentally. To address this, we used an inducible CM knockdown (KD) mouse model and found that decreased CM eliminated leukemia cells from the peripheral blood and spleen, but not the bone marrow, despite all populations exhibiting significantly decreased CM mRNA and protein. The surviving CM KD cells in the bone marrow showed decreased apoptosis and proliferation, and increased expression of autophagy related genes. Surprisingly, with prolonged KD of CM, ~40% of mice re-established disease despite maintaining decreased CM. Our work indicates that CM is required for leukemia survival in the spleen and peripheral blood, but in the bone marrow CM KD leukemia cells can survive and re-establish disease independent of the fusion protein. These findings imply that targeting CM alone has potential to reduce leukemic burden but not cure the disease.

5. GSE343104 单细胞转录组学揭示斑马鱼固有淋巴细胞的异质性图谱

- 🏷️ 关键词:single-cell、transcriptomics
- 📝 描述:Contributors : Kefan Cheng ; Thi Huong Trinh ; Ying Cao ; Shachuan Feng ; Jiaxin Liang ; Shizheng Zhao ; Jiaxu Yin ; Tao Dong ; Zilong WenSeries Type : Expression profiling by high throughput sequencingOrganism : Danio rerioInnate lymphoid cells (ILCs) are a class of lymphocytes whose activation is independent of antigen receptors. They constitute a major lymphocyte compartment and likely play a prominent role in lower vertebrates, though their precise composition and functions remain poorly characterized. Here, using scRNA-seq, we identify a broad spectrum of distinct ILC subsets, including both conventional subsets resembling their mammalian counterparts and unconventional ILC-like populations with unique features and distinct tissue distributions. We demonstrate that the complete ILC repertoire emerges early in development, independent of hematopoietic stem cells (HSCs), yet is maintained into adulthood via an HSC-dependent mechanism. Our work defines the landscape and ontogeny of zebrafish ILCs, revealing their underappreciated diversity and providing key insights into vertebrate innate immunity evolution.

6. GSE305345 LINE-1 ORF1p 是癌症中一种共享的免疫原性抗原
- ✍️ 作者:未知作者
- 🏷️ 关键词:cancer、antigen
- 📝 描述:Contributor : Diao LiyangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensIn this study, we identify and characterize LINE-1 ORF1p as a shared and immunogenic cancer antigen. LINE-1 elements are normally repressed genomic sequences that can be reactivated in cancer. We demonstrate that ORF1p, a protein encoded by LINE-1, is selectively expressed in tumors and its peptides are presented on MHC class I molecules across diverse tumor types. Using public and newly generated immunopeptidomics datasets, we detect ORF1p-derived peptides in a tumor-specific manner. Functional assays confirm that these peptides can elicit IFN-γ responses from CD4+ and CD8+ T cells in vitro. These findings highlight ORF1p as a promising candidate for a broadly applicable cancer vaccine.

8. GSE343701 代谢重编程通过 GLS1 调节慢性肾脏病中的心肌细胞肥大
- ✍️ 作者:未知作者
- 🏷️ 关键词:metabolic
- 📝 描述:Contributors : Linnan Bai ; Yi Wang ; Junnan WuSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusLeft ventricular hypertrophy (LVH) is critical in chronic kidney disease (CKD), but its mechanisms remain unclear. This study employed multi-omics approaches, including RNA-seq and integrated metabolomics, to characterize metabolic alterations in cardiomyocytes (CM) of CKD mice, revealing enhanced glutaminolysis and impaired oxidative phosphorylation. We identified that glutaminase 1 (GLS1), the rate-limiting enzyme of glutaminolysis, is significantly upregulated and enzymatically activated in CM under CKD conditions. A multi-center cohort study confirmed that serum-induced GLS1 activity was associated with LV hypertrophic remodeling. Cardiomyocyte-specific deletion or pharmacological inhibition of GLS1 attenuated CKD-induced cardiac hypertrophy. Proteomic analysis revealed that multiple circulating proteins in the serum of CKD patients are associated with GLS1 enzymatic activity. Furthermore, phosphate (Pi), a representative uremic toxin, functions as a critical modulator of GLS1 activity and expression, compromising mitochondrial bioenergetics by promoting ammonia production and reducing mitochondrially encoded respiratory chain proteins. These integrated metabolic effects underscore the pivotal role of GLS1 in orchestrating myocardial energy reprogramming, thereby contributing to CKD-induced LVH.

Accurate preclinical modelling of HGSOC biological complexity is essential to improve translational research outcomes and therapeutic development; however, traditional 2D models have limited translational relevance. We therefore compared the morphological, proliferative, and molecular characteristics of four HGSOC cell lines (OVCAR-4, OVSAHO, COV362, and Kuramochi) in 2D versus 3D culture environments. To support systematic interrogation of 3D models, we developed reproducible protocols for 3D spheroid generation and optimized a dissociation method for downstream analysis. We observed significant differences in cellular behaviour, morphology, cell cycle regulation, and gene expression. Kuramochi cells showed upregulated EMT markers WNT11B and VIM, suggesting an increased invasive phenotype, i.e., enhanced epithelial–mesenchymal transition and signalling pathways. In OVSAHO cells, MMP2 was significantly downregulated while VEGFA was upregulated, highlighting alterations in matrix remodelling and angiogenesis, characterizing this cell line as proliferative rather than invasive. COV362 cells showed an initial decrease followed by an increase in KI67 expression. Downregulation of BRCA1 and KI67 indicates reduced cell proliferation in 3D environments. Proliferation kinetics were also altered in 3D environments: Kuramochi and OVCAR-4 adopted a more quiescent phenotype, while COV362 remained more proliferative with significant KI67 overexpression. These proliferation dynamics were confirmed with immunocytochemistry. Alignment of expression data showed that different cell types align with distinct HGSOC subtypes: OVASHO with immunoreactive, OVCAR4 with mesenchymal and differentiated, COV362 with differentiated and proliferative, and Kuramochi with proliferative subtype. The described 3D models can serve as high-throughput platforms for drug testing and functional studies, as well as for studying the complex molecular dynamics of ovarian cancer. Moreover, co-culturing systems can enhance their translational potential for the developme…
