Glioblastoma multiforme (GBM) is the most malignant primary tumour in the central nervous system, but the molecular mechanisms underlying its pathogenesis remain unclear. In this study, data set GSE50161 was used to construct a co‐expression network for weighted gene co‐expression network analysis. Two modules (dubbed brown and turquoise) were found to have the strongest correlation with GBM. Functional enrichment analysis indicated that the brown module was involved in the cell cycle, DNA replication, and pyrimidine metabolism. The turquoise module was primarily related to circadian rhythm entrainment, glutamatergic synapses, and axonal guidance. Hub genes were screened by survival analysis using The Cancer Genome Atlas and Human Protein Atlas databases and further tested using the GSE4290 and Gene Expression Profiling Interactive Analysis databases. The eight hub genes (NUSAP1, SHCBP1, KNL1, SULT4A1, SLC12A5, NUF2, NAPB, and GARNL3) were verified at both the transcriptional and translational levels, and these gene expression levels were significant based on the World Health Organization classification system. These hub genes may be potential biomarkers and therapeutic targets for the accurate diagnosis and management of GBM.
Subarachnoid hemorrhage (SAH) is a fatal pathological condition in the central nervous system (CNS), characterized by severe clinical consequences. Its treatment remains a significant challenge, especially due to the incomplete understanding of its molecular mechanisms. In this study, we integrated comprehensive bioinformatics analyses with experimental validation to explore the potential pathogenic mechanisms and immune cell infiltration characteristics of SAH, aiming to identify novel diagnostic biomarkers and therapeutic targets. We selected relevant gene expression data from the gene expression omnibus (GEO) database and obtained a gene set associated with SAH from the GeneCards database. Through bioinformatics analysis, we constructed a protein-protein interaction (PPI) network and performed functional enrichment analysis using gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) databases. The analysis revealed 11 key genes and indicated 3 main signaling pathways. Additionally, Drug target prediction and molecular docking analyses revealed that Isorhynchophylline (IRN) exhibits a strong binding affinity to these hub proteins. Importantly, Western blot (WB) experiments confirmed that IRN significantly downregulates the expression of CCL20, IL6, TLR4, and MMP9 in LPS-induced microglial cells, validating its anti-inflammatory effects. In conclusion, our findings not only elucidate the molecular mechanisms underlying SAH but also provide robust bioinformatics and experimental evidence supporting IRN as a promising therapeutic candidate, offering novel insights for future intervention strategies in SAH.

Alzheimer’s disease (AD) is a neurodegenerative disorder primarily affecting the geriatric population, characterized by progressive cognitive impairment and behavioral abnormalities. Due to the absence of effective disease-modifying therapies, AD imposes a substantial burden on patients and their families. The etiology and pathogenesis of AD have not been fully elucidated; multiple pathological alterations have been implicated, including the deposition of β-amyloid (Aβ) plaques, abnormal tau phosphorylation, and neuroinflammatory responses. These pathological changes contribute to neuronal damage, synaptic dysfunction, and neuronal death, ultimately leading to brain atrophy. Recent studies have identified PANoptosis as a critical regulatory mechanism of programmed cell death that influences the pathological progression of AD through multiple pathways, including modulation of Aβ plaque deposition and regulating neuroinflammatory responses. However, the precise mechanisms of these effects remain unclear. This review aims to comprehensively analyze recent research findings, focusing on the regulatory role of PANoptosis in AD, exploring the specific manifestations of the intricate network of cell death regulation in AD pathogenesis. By providing a systematic overview of emerging findings, this review offers new insights into the pathogenesis of AD and highlights potential directions for the development of targeted therapeutic strategies.
