Bioinformatics analysis of potential common pathogenic mechanisms for systemic lupus erythematosus and acute...

Area of Science:

• Molecular biology
• Immunology
• Cardiology

Background:

• Patients with systemic lupus erythematosus (SLE) face an elevated risk of acute myocardial infarction (AMI).
• The shared molecular mechanisms underlying this increased risk remain largely unelucidated.
• This research investigates the common molecular underpinnings connecting SLE and AMI.

Purpose of the Study:

• To identify common molecular mechanisms between SLE and AMI.
• To uncover potential therapeutic targets for AMI in SLE patients.
• To provide a foundation for future research into the pathogenesis of this complication.

Main Methods:

• Comparative analysis of gene expression profiles from SLE (GSE50772) and AMI (GSE66360) datasets.
• Identification of common differentially expressed genes (DEGs) between the two conditions.
• Construction and analysis of protein-protein interaction (PPI) networks, regulatory networks, and identification of hub genes.

Main Results:

• 70 common DEGs (7 downregulated, 63 upregulated) were identified between SLE and AMI.
• Enrichment analysis revealed involvement in IL-17 signaling, TNF signaling, lipid metabolism, and atherosclerosis pathways.
• 12 significant hub genes, including IL1B, TNF, and FOS, were identified as key players.

Conclusions:

• This study elucidates shared pathogenic pathways between SLE and AMI.
• The identified hub genes and pathways offer novel perspectives for understanding and treating AMI in SLE patients.
• Findings may guide clinical strategies for the prevention and management of cardiovascular complications in SLE.
