The Role of Histone Methylation in Heart Failure: Epigenetic Mechanisms and Therapeutic Perspectives

Area of Science:

• Cardiovascular Research
• Epigenetics
• Molecular Biology

Background:

• Heart failure (HF) is a progressive cardiovascular disease with limited therapeutic options.
• Epigenetic modifications, particularly histone methylation, are increasingly recognized in HF pathogenesis.
• Histone methylation regulates critical cellular processes like gene expression, cell cycle, and apoptosis.

Purpose of the Study:

• To systematically review the diverse roles of histone methylation in HF.
• To explore the involvement of histone methylation in cardiac regeneration, hypertrophy, fibrosis, apoptosis, metabolic remodeling, and inflammation.
• To assess the therapeutic potential of targeting histone methylation enzymes in HF.

Main Methods:

• Systematic literature review of histone methylation's role in heart failure.
• Analysis of preclinical studies investigating histone methylation inhibitors.
• Synthesis of findings on cellular and molecular mechanisms in HF.

Main Results:

• Histone methylation is implicated in multiple HF pathological processes, including cardiac hypertrophy, fibrosis, and apoptosis.
• Inhibitors targeting histone methylation enzymes demonstrate anti-hypertrophic, anti-fibrotic, and cardioprotective effects in animal models.
• These epigenetic modifications influence cardiac regeneration, metabolism, and inflammation.

Conclusions:

• Histone methylation is a critical regulator in the development and progression of heart failure.
• Targeting histone methylation pathways presents a promising therapeutic strategy for HF.
• Further research into histone methylation inhibitors could lead to significant clinical advancements for HF patients.
