Critical roles of m

Area of Science:

• Molecular Biology
• Epigenetics
• Cardiology

Background:

• Cardiovascular diseases (CVDs) are a leading global cause of mortality, with complex and not fully understood pathogenesis.
• N6-methyladenosine (m6A) methylation, the most prevalent mRNA epigenetic modification, is increasingly recognized for its role in cardiac physiology and pathology.
• m6A modifications are regulated by writers, erasers, and readers, influencing various cellular processes.

Purpose of the Study:

• To review the molecular functions of m6A enzymes in the context of cardiovascular diseases.
• To elucidate m6A-associated mechanisms and functions, particularly in heart failure and ischemic heart disease.
• To discuss the potential clinical applications and translation of m6A modifications in CVDs.

Main Methods:

• Literature review focusing on m6A methylation in cardiovascular research.
• Analysis of molecular mechanisms linking m6A to cardiac function and dysfunction.
• Synthesis of current understanding of m6A's role in heart failure and ischemia.

Main Results:

• m6A methylation influences critical cardiac processes including calcium homeostasis, endothelial function, cell death, autophagy, ER stress, and inflammation.
• Specific m6A enzymes (writers, erasers, readers) play significant roles in the development and progression of CVDs.
• m6A dysregulation is implicated in the pathogenesis of heart failure and ischemic heart disease.

Conclusions:

• m6A epigenetic modifications are integral to cardiovascular health and disease.
• Targeting m6A pathways presents a promising avenue for novel therapeutic strategies in CVDs.
• Further research into m6A modification holds potential for clinical transformation in managing cardiovascular conditions.
