Understanding cardiovascular disease: a journey through the genome (and what we found there)

Area of Science:

• Genomics
• Molecular Biology
• Cardiovascular Medicine

Background:

• Cardiovascular disease (CVD) is a leading global cause of death and hospitalization.
• Identified risk factors explain only a portion of CVD cases, prompting research into genetics and genomics.
• Previous genetic studies, except for Mendelian conditions, faced challenges in pinpointing specific CVD-related genomic components.

Purpose of the Study:

• To explore the role of genomics in understanding the unexplained risk factors for cardiovascular disease.
• To bridge the gap between genetic variations identified by genome-wide association studies (GWAS) and underlying molecular mechanisms.
• To investigate how multilayered gene expression regulation influences CVD development.

Main Methods:

• Review of genetic and genomic research in cardiovascular disease.
• Analysis of genome-wide association studies (GWAS) findings.
• Exploration of regulatory mechanisms including chromatin remodeling, regulatory elements, microRNAs, and alternative splicing.

Main Results:

• Genome-wide association studies (GWAS) are beginning to elucidate molecular mechanisms linked to genetic variations.
• Understanding gene regulation layers (chromatin, regulatory elements, microRNAs, splicing) is essential for interpreting genetic associations.
• The complex interplay between DNA information and regulatory layers is key to CVD pathogenesis.

Conclusions:

• Genomic insights are vital for unraveling the complex causes of cardiovascular disease.
• Connecting genetic variations with gene expression regulation offers a path to better CVD prediction.
• This integrated approach holds promise for developing more effective cardiovascular therapies.
