Epigenetic modification: a regulatory mechanism in essential hypertension

Area of Science:

• Cardiovascular Science
• Epigenetics
• Molecular Biology

Background:

• Essential hypertension (EH) is a complex cardiovascular disease influenced by genetic and environmental factors.
• Existing genetic findings alone do not fully explain blood pressure variability in EH.
• Epigenetic modifications are increasingly recognized as critical contributors to EH pathogenesis.

Purpose of the Study:

• To review the role of specific epigenetic mechanisms in essential hypertension.
• To highlight DNA methylation, post-translational histone modifications, and microRNAs as key epigenetic factors in EH.
• To explore the potential of epigenetic modifications for future EH prevention and therapeutic strategies.

Main Methods:

• Literature review focusing on epigenetic mechanisms in essential hypertension.
• Analysis of studies investigating DNA methylation patterns in EH.
• Examination of research on histone modifications and microRNAs associated with EH and blood pressure regulation.

Main Results:

• DNA methylation, both global and gene-specific, is a well-studied epigenetic hallmark in EH.
• Post-translational histone modifications (methylation, acetylation, phosphorylation) are significant epigenetic markers linked to EH.
• MicroRNAs regulate blood pressure by targeting key genes, including those in the renin-angiotensin-aldosterone system.

Conclusions:

• Epigenetic modifications, including DNA methylation, histone modifications, and microRNAs, play a substantial role in essential hypertension.
• These epigenetic mechanisms are implicated in various cardiovascular diseases and offer promising avenues for EH research.
• Targeting epigenetic modifications could lead to novel strategies for the prevention and treatment of essential hypertension.
