Abstract:
Atherosclerosis, one of the main pathologic entities considered epidemic and a worldwide public health problem, is currently under constant review as regards its basic determining mechanisms and therapeutic possibilities. In this regard, all patients afflicted with the disease exhibit mitochondrial dysfunction, oxidative stress and inflammation. Interestingly, nitric oxide - a known vasoactive messenger gas - has been closely related to the inflammatory, oxidative and mitochondrial dysfunctional process that characterizes atherosclerosis. In addition, it has recently been demonstrated that alterations in the bioavailability of nitric oxide would induce the expression of heat shock proteins. This agrees with the use of functional foods as a strategy to prevent both vascular aging and the development of atherosclerosis. Finally, a greater knowledge regarding the mechanisms implied in the development of atherosclerosis will enable proposing new and possible hygiene, health and therapeutic interventions.
Insights
Atherosclerosis involves mitochondrial dysfunction, oxidative stress, and inflammation. Nitric oxide (NO) bioavailability is linked to these processes and may influence heat shock protein expression, suggesting functional foods for prevention.
Area of Science:
- Cardiovascular Research
- Pathophysiology
- Molecular Biology
Background:
- Atherosclerosis is a global health issue with complex mechanisms.
- Mitochondrial dysfunction, oxidative stress, and inflammation are hallmarks of the disease.
- Nitric oxide (NO) plays a critical role in these pathological processes.
Purpose of the Study:
- To explore the relationship between nitric oxide bioavailability and atherosclerosis.
- To investigate the role of NO in oxidative stress, inflammation, and mitochondrial dysfunction.
- To examine the connection between NO alterations and heat shock protein expression.
Main Methods:
- Review of existing literature on atherosclerosis mechanisms.
- Analysis of the role of nitric oxide in cellular dysfunction.
- Investigation of functional foods as a preventive strategy.
Main Results:
- Patients with atherosclerosis exhibit mitochondrial dysfunction, oxidative stress, and inflammation.
- Nitric oxide is closely implicated in the inflammatory, oxidative, and mitochondrial processes of atherosclerosis.
- Altered nitric oxide bioavailability may induce heat shock protein expression.
Conclusions:
- Understanding atherosclerosis mechanisms is key to developing new interventions.
- Functional foods show promise for preventing vascular aging and atherosclerosis.
- Targeting nitric oxide pathways could offer therapeutic benefits.

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
