Potential regulatory role of epigenetic RNA methylation in cardiovascular diseases

Area of Science:

• Molecular Biology
• Epigenetics
• Cardiology

Background:

• Cardiovascular diseases (CVDs) are a leading global cause of death and hospitalization.
• Existing prevention and treatment strategies face challenges due to the increasing incidence of cardiovascular events.
• Emerging evidence highlights the significant role of regulatory RNAs in CVD pathogenesis.

Purpose of the Study:

• To review the current understanding of RNA methylation's role in cardiovascular disease pathophysiology.
• To explore the potential of epigenetic modifications, specifically RNA methylation, as therapeutic targets for CVDs.

Main Methods:

• Comprehensive literature review of studies investigating RNA modifications in cardiac diseases.
• Analysis of research focusing on specific RNA methylation types, including N6-methyladenosine, N1-methyladenosine, 5-methylcytosine, N7-methylguanosine, N4-acetylcytidine, and 2'-O-methylation.
• Examination of the functional impact of these modifications on cardiomyocyte processes.

Main Results:

• Multiple RNA methylation marks are implicated in the regulation of cardiomyocyte functions such as cell growth, immunity, DNA damage response, calcium signaling, apoptosis, and aging.
• These epigenetic modifications are increasingly recognized as crucial contributors to the development and progression of various cardiac diseases.
• Specific RNA methylation patterns correlate with altered cellular functions relevant to CVDs.

Conclusions:

• RNA methylation represents a critical layer of epigenetic regulation in the heart.
• Targeting RNA methylation pathways offers a promising novel therapeutic avenue for cardiovascular diseases.
• Further research into the precise mechanisms of RNA methylation in CVDs is warranted for clinical translation.
