Correlation between elevated HCLS1 levels and heart failure: A diagnostic biomarker

Area of Science:

• Cardiovascular Biology
• Molecular Biology
• Genomics

Background:

• The relationship between hematopoietic cell-specific lyn substrate 1 (HCLS1) expression and heart failure (HF) is not well understood.
• Investigating gene expression patterns in HF can reveal novel insights into disease mechanisms.

Purpose of the Study:

• To explore the correlation between HCLS1 expression and heart failure.
• To identify key genes and pathways involved in the pathogenesis of heart failure.

Main Methods:

• Analysis of heart failure datasets (GSE192886, GSE196656) from the Gene Expression Omnibus (GEO) database.
• Utilized weighted gene co-expression network analysis, protein-protein interaction (PPI) networks, and functional enrichment analysis.
• Screened microRNAs (miRNAs) targeting differentially expressed genes (DEGs) using TargetScan.

Main Results:

• Identified 500 DEGs primarily associated with leukocyte activation, protein phosphorylation, cell adhesion, PI3K Akt, Notch signaling pathways, and right ventricular cardiomyopathy.
• The PPI network highlighted 15 core genes, including HCLS1, FERMT3, and LYN.
• Four genes (EP300, CD53, HCLS1, LYN) showed high expression in HF tissues and were linked to cardiovascular diseases, inflammation, and necrosis.

Conclusions:

• HCLS1 is significantly upregulated in heart failure tissues.
• The identified core genes and pathways offer potential targets for understanding and treating heart failure.
• HCLS1 may serve as a potential biomarker for heart failure.
