Ferroptosis: a new strategy for cardiovascular disease

Area of Science:

• Biochemistry
• Cardiovascular Medicine
• Cell Biology

Background:

• Cardiovascular disease (CVD) is a leading cause of mortality worldwide.
• Iron is essential for numerous physiological processes but its imbalance (deficiency or excess) poses health risks.
• Excess iron contributes to cardiac dysfunction through ferroptosis, a distinct form of programmed cell death.

Purpose of the Study:

• To review the latest research on the mechanism of ferroptosis in cardiovascular disease.
• To elucidate the role of ferroptosis and its association with microRNAs (miRNAs) in CVD pathogenesis.
• To summarize the therapeutic potential of ferroptosis-related interventions for CVD.

Main Methods:

• Literature review of recent studies on ferroptosis and cardiovascular disease.
• Analysis of the biochemical pathways involved in iron-mediated ferroptosis, including the Fenton reaction.
• Exploration of the interplay between ferroptosis and microRNAs in the context of CVD.

Main Results:

• Ferroptosis, characterized by lipid peroxidation and REDOX imbalance, is a key mechanism in the pathophysiology of CVD.
• Specific microRNAs are implicated in regulating ferroptosis pathways relevant to cardiovascular conditions.
• Excess iron accumulation significantly contributes to heart damage via ferroptosis.

Conclusions:

• Ferroptosis represents a novel therapeutic target for cardiovascular diseases.
• Understanding the ferroptosis-miRNA axis offers new avenues for CVD treatment strategies.
• Targeting ferroptosis pathways or using ferroptosis inhibitors shows promise for managing CVD.
