The dark genome in cardiovascular medicine

Area of Science:

• Genomics and Cardiovascular Medicine

Background:

• Only 1%-2% of the human genome codes for proteins; the rest is non-coding DNA, termed the 'dark genome'.
• The dark genome includes regulatory elements, repetitive sequences, and non-coding RNA (ncRNA) genes, increasingly recognized for regulating gene expression and disease.
• ncRNAs are emerging as key regulators of cardiovascular health and disease.

Purpose of the Study:

• To review major dark genome components implicated in cardiovascular disease.
• To emphasize elements with emerging mechanistic understanding and translational relevance.

Main Methods:

• Review of current literature on dark genome elements and cardiovascular disease.
• Analysis of advances in genome analysis technologies.

Main Results:

• The dark genome plays a significant role in cardiovascular traits and disease.
• Specific dark genome elements, particularly ncRNAs, are critical regulators.
• Advances in genomic analysis are clarifying the dark genome's role in cardiovascular conditions.

Conclusions:

• Understanding the dark genome offers new therapeutic targets for cardiovascular disease prevention and management.
• Further mechanistic insight into the dark genome will drive innovation in cardiovascular therapeutics.
