- Spermatogenesis requires precise spatial and temporal regulation of RNA splicing, orchestrated by both the major (U1, U2, and U4/U6/U5) and minor (U11, U12, and U4atac/U6atac/U5) spliceosomal small nuclear ribonucleoproteins (snRNPs), yet their function during germ cell development remain poorly defined. Here, we elucidate the essential function of LSM7, a component of the LSM2-8 complex, in snRNP biogenesis and the process of spermatogenesis. Our results demonstrate that LSM7 governs the stability of U6 small nuclear RNA (snRNA) within Cajal bodies and directly interacts with scaRNA2, scaRNA13, and scaRNA17 to modulate 2'-O-methylation and pseudouridylation modifications of U2 and U12 snRNAs. Loss of LSM7 results in defective nuclear localization and reduced stability of U2, U5, and U6 snRNAs, destabilization of their corresponding snRNP complexes, and aberrant splicing events, notably affecting mutually exclusive exons and exon skipping. These splicing defects lead to translational dysregulation, ultimately impairing the differentiation of spermatogonial stem cells into spermatogonia. Our findings identify LSM7 as a pivotal regulator linking scaRNA-guided snRNA modifications, spliceosomal fidelity, and the determination of spermatogonial stem cell fate, offering important mechanistic insights into the post-transcriptional regulation of male germ cell development. - Source: PubMed

We integrated differential expression analysis, weighted gene co-expression network analysis (WGCNA), and protein-protein interaction (PPI) network pharmacology to identify CRC hub genes and their ion channel connections, validated by dual single-cell perturbation approaches: variational graph autoencoder-based virtual knockout (VGAE-KO) and experimental HCT116 CRISPRi Perturb-seq (6 genes, 8445 cells). WGCNA identified 100 hub genes spanning three functional programs. Ribosomal proteins link to K channels ( → , targetable by EMA-approved ataluren, passed dual validation at 97.8th-98.7th percentile). RNA processing genes connect to Cl channels ( → , strongest signal at 99.8th-99.4th percentile). Immune checkpoint receptors (, ) connect via PPI intermediates to Ca2+ and K channels, targetable by relatlimab (FDA-approved) and varlilumab (Phase 2). This work maps previously unknown links between CRC driver genes and ion channel regulation, with the ataluren-- axis ready for pharmacological testing. - Source: PubMed

Zhou JianyingQiu TingtingHu ZhenzhenXiao DanLiu Zhentian - Ischemic stroke (IS) remains a leading cause of death and disability, with limited effective treatments in the acute phase. Mitophagy, the selective degradation of damaged mitochondria, plays a crucial role in cellular homeostasis and survival during IS. However, its exact mechanisms in stroke pathophysiology remain unclear. This study utilized a multi-omics approach, integrating gene expression data from bulk and single-cell RNA sequencing, to investigate the role of mitophagy-related genes (MRGs) in IS. We identified differentially expressed MRGs (DE-MRGs) in IS using bioinformatics techniques, including weighted gene co-expression network analysis (WGCNA) and machine learning models, which led to the identification of five core biomarkers: SRPRB, ATP5J, LSM7, DEGS1, and TGDS. Validation via qPCR and analysis of immune cell infiltration further supported their relevance. Single-cell analysis revealed significant differences in mitophagy activity in microglial subpopulations, with ATP5J showing dynamic expression patterns linked to stroke-induced mitochondrial dysfunction. Additionally, pseudo-time analysis suggested a progressive shift from homeostatic to disease-associated microglial states. Our findings highlight the complexity of mitophagy regulation in IS and suggest that targeting mitophagy-related pathways, such as ATP5J, could provide novel therapeutic strategies for IS management. - Source: PubMed

Cao ZhanWang YingluanSun MingjianDu RunyiFeng XuWang LinZhao ZiyiSun Wei - ObjectiveHepatocellular carcinoma (HCC) has a poor prognosis, necessitating novel biomarkers. The role of (Like-Sm protein 7), an RNA-binding protein, in HCC remains unclear.MethodsWe employed a multiomics strategy using transcriptomic data from TCGA, GTEx, GEO, and ICGC to evaluate 's expression and prognostic value. A protein-protein interaction (PPI) network was constructed via STRING, followed by Gene Ontology/KEGG/Gene Set Enrichment Analysis (GSEA) functional enrichment analysis. The relationship between and the immune infiltration landscape was assessed using single-sample GSEA (ssGSEA) and the TISCH single-cell database. Drug sensitivity was analyzed using Genomics of Drug Sensitivity in Cancer, and structure-based virtual screening was performed on the ZINC library to identify potential inhibitors. Key findings were validated in clinical samples and MHCC97H cells and Huh-7 cells using Western blot, IHC, and MTT assays.Results was significantly overexpressed in HCC, correlating with adverse clinicopathological features (higher histological grade, elevated AFP levels, vascular invasion) and shorter overall survival, identifying it as an independent risk factor. Functionally, was implicated in processes such as hormone regulation. Immune analysis revealed that high expression was associated with altered immune cell abundance, upregulation of immune checkpoints, and a higher Tumor Immune Dysfunction and Exclusion score, suggesting a role in immune evasion. The high- group showed increased sensitivity to drugs like sorafenib. Virtual screening identified Velpatasvir as a top -targeting candidate, with in vitro validation confirming that it inhibits MHCC97H cells and Huh-7 cells proliferation and downregulates protein in a concentration- and time-dependent manner.ConclusionsBy integrating multiomics strategy and experimental validation, this study suggests that may play a role in HCC progression and influence the tumor immune microenvironment. may serve as a potential biomarker and therapeutic target, and Velpatasvir appears to be a candidate agent worthy of further investigation. - Source: PubMed
