Lung squamous cell carcinoma (LUSC) is a disease with high morbidity and mortality. Many studies have shown that aberrant alternative splicing (AS) can lead to tumorigenesis, and splicing factors (SFs) serve as an important function during AS. In this research, we propose an analysis method based on synergy to screen key factors that regulate the initiation and progression of LUSC. We first screened alternative splicing events (ASEs) associated with survival in LUSC patients by bivariate Cox regression analysis. Then an association network consisting of OS-ASEs, SFs, and their targeting relationship was constructed to identify key SFs. Finally, 10 key SFs were selected in terms of degree centrality. The validation on TCGA and cross-platform GEO datasets showed that some SFs were significantly differentially expressed in cancer and paracancer tissues, and some of them were associated with prognosis, indicating that our method is valid and accurate. It is expected that our method would be applied to a wide range of research fields and provide new insights in the future.

Epilepsy is a common chronic nervous system disease that threatens human health. However, the role of FOXC1 and its relations with pyroptosis have not been fully studied in epilepsy. Sprague-Dawley rats were obtained for constructing temporal lobe epilepsy (TLE) models.

Lung cancer is the leading cause of cancer-related death worldwide, and the complex molecular mechanisms underlying its development, particularly the role of alternative splicing (AS) in different subtypes, remain poorly understood. In this study, we performed RNA sequencing of 178 lung cancer patients and conducted a comprehensive analysis of the transcriptomic landscape with a focus on AS. We identified robust lung cancer- and subtype-specific AS biomarkers that were consistently effective in both tissue samples and cancer cell lines.

Transcription factors are significant regulators of gene expression in most biological processes related to diabetes, including beta cell (β-cell) development, insulin secretion and glucose metabolism. Dysregulation of transcription factor expression or abundance has been closely associated with the pathogenesis of type 1 and type 2 diabetes, including pancreatic and duodenal homeobox 1 (), neurogenic differentiation 1 (), and forkhead box protein O1 (). Gene expression is regulated at the transcriptional level by transcription factor binding, epigenetically by DNA methylation and chromatin remodelling, and post-transcriptional mechanisms, including alternative splicing and microRNA (miRNA).

The insect ionotropic γ-aminobutyric acid (GABA) receptor is an important insecticide target, and alternative splicing (AS) among exons 3a, 3b, 6a, and 6b of its RDL subunit is ubiquitous in insects; however, the AS factors and mechanisms remain unclear. While the neuro-oncological ventral antigen (Nova) is known to regulate AS of the γ2 subunit of mammalian GABA receptors, its role in insects remains unexplored. Two CsNova isoforms, CsNova-X1 and CsNova-X3, were identified by BLAST in the third-generation transcriptome of Chilo suppressalis.

Introduction: Natural killer (NK) cells are essential effectors in immune surveillance and cancer immunotherapy, but their function is often compromised by metabolic stress and environmental factors within the tumor microenvironment (TME). O-GlcNAcylation, a post-translational modification, regulates immune responses, yet its impact on NK cell function and therapeutic potential in immune cell-based therapies remains underexplored.
Objectives: This study investigates the effects of O-GlcNAcylation on NK cell-mediated cytotoxicity and its potential as a therapeutic target to enhance tumor immunity.
