Shared Gene Expression Between Multiple Sclerosis and Ischemic Stroke.

Area of Science:

• Genetics and Molecular Biology
• Neurology
• Computational Biology

Background:

• Patients with multiple sclerosis (MS) exhibit an elevated risk for ischemic stroke (IS).
• Despite differing clinical presentations, genome-wide association studies (GWAS) suggest potential shared genetic underpinnings between MS and IS.
• The molecular mechanisms connecting MS and IS remain largely unexplored.

Purpose of the Study:

• To investigate potential shared molecular mechanisms and gene expression links between multiple sclerosis and ischemic stroke.
• To identify common biological pathways implicated in both MS and IS through pathway-based analysis of GWAS data.

Main Methods:

• Performed gene-based and pathway-based analyses on genome-wide association study (GWAS) datasets for multiple sclerosis (MS) and ischemic stroke (IS).
• Identified significant gene sets for MS and IS individually.
• Conducted pathway analysis across KEGG, PANTHER, REACTOME, WikiPathways, and Gene Ontology (GO) databases to find shared pathways.

Main Results:

• Identified a significant overlap in biological pathways between MS and IS across multiple databases.
• Specifically, 9 shared pathways were found in KEGG, 2 in PANTHER, 14 in REACTOME, 1 in WikiPathways, and 194 in GO annotations (p < 0.05).
• These findings highlight common molecular pathways potentially involved in the pathogenesis of both diseases.

Conclusions:

• The study reveals shared biological pathways between multiple sclerosis and ischemic stroke, indicating common molecular mechanisms.
• These results enhance the understanding of the molecular links between MS and IS.
• The identified shared pathways may offer insights for developing novel therapeutic strategies targeting both conditions.
