Regulation of Autophagy in Cardiovascular Diseases by Natural Products

Area of Science:

• Cardiovascular Biology
• Cellular Biology
• Molecular Medicine

Background:

• Autophagy dysfunction is implicated in major cardiovascular diseases, including heart failure (HF) and atherosclerosis (AS).
• Autophagy plays a dual role: low-level induction protects cells, while excessive levels can cause damage and cell death.
• Understanding autophagy's role is crucial for developing novel cardiovascular disease treatments.

Purpose of the Study:

• To review the recent research on natural compounds and their effects on autophagy in cardiovascular diseases.
• To explore the therapeutic potential of compounds like resveratrol, curcumin, epigallocatechin-3-gallate, and Cordyceps sinensis.
• To identify autophagy regulation as a potential strategy for treating cardiovascular conditions.

Main Methods:

• Literature review of existing research on autophagy and cardiovascular diseases.
• Analysis of studies investigating natural compounds and their impact on cellular autophagy pathways.
• Synthesis of findings related to cardiac remodeling, myocardial ischemia, atherosclerosis, and heart failure.

Main Results:

• Autophagy's dual role in cardiovascular health: protective at low levels, detrimental at excessive levels.
• Natural compounds (resveratrol, curcumin, EGCG, Cordyceps sinensis) show promise in modulating autophagy for cardiovascular benefits.
• Evidence suggests these compounds can protect cardiomyocytes and vascular endothelial cells.

Conclusions:

• Modulating autophagy presents a promising therapeutic avenue for cardiovascular diseases.
• Natural compounds offer potential new drug targets for preventing and treating clinical cardiovascular diseases.
• Further research into autophagy regulation could lead to effective treatments for conditions like HF and AS.
