Potential Mechanisms Between HF and COPD: New Insights From Bioinformatics

Area of Science:

• Genomics
• Molecular Biology
• Pulmonology

Background:

• Heart failure (HF) and chronic obstructive pulmonary disease (COPD) frequently coexist and share clinical manifestations.
• Understanding their interconnectedness is crucial for effective patient management.

Purpose of the Study:

• To elucidate the co-genetic characteristics between HF and COPD.
• To identify potential shared molecular mechanisms underlying both diseases.

Main Methods:

• Downloaded gene expression datasets for HF and COPD from the Gene Expression Omnibus database.
• Identified common differentially expressed genes (DEGs) and performed functional enrichment analysis.
• Utilized GeneMANIA and CIBERSORT for network analysis and immune cell infiltration assessment.

Main Results:

• Common DEGs pointed towards the significant involvement of extracellular matrix and ribosomal signaling pathways in both HF and COPD.
• Network analysis indicated a link between these diseases and immune infiltration, with a notable role for macrophages.
• Identified 4 transcription factors (TFs) and 1408 microRNAs (miRNAs) associated with both conditions.

Conclusions:

• HF and COPD share underlying genetic and molecular pathways, particularly involving extracellular matrix, ribosomal signaling, and immune responses.
• Macrophages and specific TFs/miRNAs represent potential therapeutic targets.
• Salbutamol may exert a positive influence on these shared molecular pathways.
