Review: Acetylation mechanisms and targeted therapies in cardiac fibrosis

Area of Science:

• Cardiovascular Biology
• Molecular Medicine
• Epigenetics

Background:

• Cardiac fibrosis is a pathological remodeling process in cardiovascular diseases, often leading to heart failure.
• Current therapies for cardiac fibrosis are limited, necessitating novel treatment strategies.
• Abnormal cardiac fibroblast activity drives excessive extracellular matrix deposition in the myocardium.

Purpose of the Study:

• To review the critical roles of acetylation modifications in cardiac fibrosis.
• To explore how acetylation regulates key pathogenic conditions in fibrosis.
• To propose acetylation-targeting strategies for cardiac fibrosis prevention and treatment.

Main Methods:

• Literature review of studies on acetylation and cardiac fibrosis.
• Analysis of the role of acetyltransferases and deacetylases in fibrosis.
• Synthesis of findings on acetylation's impact on oxidative stress, mitochondrial dysfunction, and metabolism.

Main Results:

• Acetylation, a protein modification, significantly contributes to cardiac fibrosis development.
• Dynamic alterations in acetylation, regulated by enzymes, influence fibrotic processes.
• Acetylation impacts critical pathways including oxidative stress, mitochondrial function, and energy metabolism.

Conclusions:

• Acetylation modifications are pivotal in the pathogenesis of cardiac fibrosis.
• Targeting acetylation pathways presents a promising therapeutic avenue for cardiac fibrosis.
• Further research into acetylation-targeting strategies could lead to effective treatments for heart failure.
