Glutathione Participation in the Prevention of Cardiovascular Diseases

Area of Science:

• Biochemistry
• Cardiology
• Molecular Biology

Background:

• Cardiovascular diseases (CVD) are a leading cause of global mortality.
• Oxidative stress, driven by reactive oxygen species (ROS) and reactive nitrogen species (RNS), exacerbates CVD.
• Key ROS/RNS include superoxide anion, hydroxyl radical, nitric oxide, hydrogen peroxide, hypochlorous acid, and peroxynitrite.

Purpose of the Study:

• To review the critical role of reduced glutathione (GSH) in mitigating oxidative stress in cardiovascular pathologies.
• To examine the synthesis and regeneration of GSH in vital organs like the heart and liver.
• To highlight GSH's importance in preventing or reducing detrimental ROS effects in CVD.

Main Methods:

• Literature review focusing on the biochemical mechanisms of oxidative stress in CVD.
• Analysis of studies detailing glutathione synthesis and regeneration pathways.
• Examination of research on the protective effects of GSH against ROS/RNS in cardiovascular conditions.

Main Results:

• Reduced glutathione (GSH) is a crucial endogenous antioxidant.
• GSH synthesis and regeneration are vital for cellular defense against oxidative damage in the heart and liver.
• Adequate GSH levels are associated with reduced severity and progression of cardiovascular diseases.

Conclusions:

• Glutathione plays a significant protective role against oxidative stress in cardiovascular diseases.
• Maintaining optimal GSH levels through synthesis and regeneration is essential for cardiovascular health.
• Targeting GSH pathways may offer therapeutic strategies for managing CVD.
