Roles of different methylation modifications in cardiovascular disease

Area of Science:

• Molecular Biology
• Cardiology
• Epigenetics

Background:

• Cardiovascular diseases (CVDs) are leading causes of global mortality and disability.
• Effective prevention and therapy require deep understanding of molecular mechanisms.
• Epigenetic modifications, particularly methylation, are increasingly recognized in CVD pathogenesis.

Purpose of the Study:

• To review the biological processes of DNA, protein, and RNA N⁶-methyladenosine (m⁶A) methylation.
• To summarize the roles of these methylation modifications in major cardiovascular diseases.
• To highlight the potential of epigenetic mechanisms as therapeutic and diagnostic targets for CVDs.

Main Methods:

• Literature review of recent advancements in epigenetic research.
• Focus on methylation modifications: DNA methylation, protein methylation, and m⁶A RNA modification.
• Synthesis of findings related to CVDs including cardiac hypertrophy, heart failure, ischemic heart disease, and atherosclerosis.

Main Results:

• Methylation modifications significantly impact gene expression relevant to cardiovascular health.
• Specific roles of DNA, protein, and m⁶A methylation are identified in cardiac hypertrophy, heart failure, ischemic heart disease, and atherosclerosis.
• Epigenetic alterations are implicated in the progression and pathogenesis of various cardiovascular conditions.

Conclusions:

• Epigenetic methylation modifications are integral to cardiovascular disease development and progression.
• Targeting these methylation mechanisms presents promising avenues for novel diagnostic and therapeutic strategies in cardiology.
• Further research into epigenetic modulation is critical for advancing cardiovascular medicine.
