Relationship between PPAR-γ gene polymorphisms and ischemic stroke risk: A meta-analysis

Identification and prediction of molecular factors associated with ischemic stroke: an integrative analysis of DEGs, TFs, and PPI networks

Ischemic stroke (IS) is a complex neurological disorder characterized by the sudden disruption of blood flow to the brain, leading to severe and often irreversible damage. Despite advances in stroke management, the underlying molecular mechanisms and key factors involved in the development and progression of IS remain elusive. In recent years, the integration of high-throughput data analysis techniques has emerged as a powerful approach to unraveling the molecular intricacies of complex diseases. In this study, we comprehensively analyzed gene expression, protein-protein interactions (PPI), and gene regulatory networks to identify IS-associated molecular factors. We utilized publicly available datasets and employed bioinformatics tools to analyze the data. Our analysis revealed many differentially expressed genes (DEGs) in IS, with a predominant down-regulation of genes. Gene ontology (GO) analysis highlighted the involvement of various biological processes, including transcriptional regulation, cell cycle, immune system processes, and cell differentiation. These findings underscore the complexity of stroke pathology, involving dysregulated gene expression and disrupted cellular processes. Constructing PPI networks enabled us to identify specific subnetworks associated with critical biological processes relevant to stroke, such as nucleosome assembly, protein translation, glycosylation, protein folding, and mRNA splicing. These subnetworks provide insights into the dysregulated molecular mechanisms contributing to stroke progression. Furthermore, we focused on identifying differentially expressed transcription factors (DE-TFs) within the gene regulatory network. Several up-regulated DE-TFs, including E2F1, MYB, GFI1B, and NUCKS1, were identified, suggesting their potential involvement in the dysregulation of gene expression in IS.

Common Genetic Factors and Pathways in Alzheimer's Disease and Ischemic Stroke: Evidences from GWAS

Alzheimer's disease (AD) and ischemic stroke (IS) are common neurological disorders, and the comorbidity of these two brain diseases is often seen. Although AD and IS were regarded as two distinct disease entities, in terms of different etiologies and clinical presentation, recent genome-wide association studies (GWASs) revealed that there were common risk genes between AD and IS, indicating common molecular pathways and their common pathophysiology. In this review, we summarize AD and IS risk single nucleotide polymorphisms (SNPs) and their representative genes from the GWAS Catalog database, and find thirteen common risk genes, but no common risk SNPs. Furthermore, the common molecular pathways associated with these risk gene products are summarized from the GeneCards database and clustered into inflammation and immunity, G protein-coupled receptor, and signal transduction. At least seven of these thirteen genes can be regulated by 23 microRNAs identified from the TargetScan database. Taken together, the imbalance of these molecular pathways may give rise to these two common brain disorders. This review sheds light on the pathogenesis of comorbidity of AD and IS, and provides molecular targets for disease prevention, manipulation, and brain health maintenance.

The medicinal perspective of 2,4-thiazolidinediones based ligands as antimicrobial, antitumor and antidiabetic agents: A review

2,4-Thiazolidinedione (2,4-TZD), commonly known as glitazone, is a ubiquitous heterocyclic pharmacophore possessing a plethora of pharmacological activities and offering a vast opportunity for structural modification. The diverse range of biological activities endowed with a novel mode of action, low cost, and easy synthesis has attracted the attention of medicinal chemists. Several researchers have integrated the TZD core with different structural fragments to develop a wide range of lead molecules against various clinical disorders. The most common sites for structural modifications at the 2,4-TZD nucleus are the N-3 and the active methylene at C-5. The review covers the recent development of TZD derivatives such as antimicrobial, anticancer, and antidiabetic agents. Various 2,4-TZD based agents or drugs, which are either under clinical development or in the market, are discussed in the study. Different synthetic methodologies for synthesizing the 2,4-TZD core are also included in the manuscript. The importance of various substitutions at N-3 and C-5 and the mechanisms of action and structure-activity relationships are also discussed. We hope this study will serve as a valuable tool for the scientific community engaged in the structural exploitation of the 2,4-TZD core for developing novel drug m\olecules for life-threatening ailments.
