Insights
Endothelial dysfunction, an early sign of atherosclerosis, involves molecular mechanisms like oxidative stress and amino acid metabolism. Understanding these processes is key to developing new therapies for cardiovascular diseases.
Area of Science:
- Cardiovascular Research
- Molecular Biology
- Pathophysiology
Background:
- Endothelial dysfunction is an early indicator of atherosclerosis.
- Vascular calcification is common in aging, diabetes, and cardiovascular diseases, contributing to mortality.
- Molecular mechanisms underlying endothelial remodeling are crucial for disease progression.
Purpose of the Study:
- To elucidate the molecular mechanisms driving endothelium remodeling in disease.
- To explore the roles of oxidative stress, osteogenic factors, and amino acid metabolism in vascular calcification.
- To identify potential therapeutic targets for endothelial dysfunction.
Main Methods:
- Review of molecular pathways involved in endothelial dysfunction.
- Analysis of the impact of oxidative stress on vascular smooth muscle cells (SMC).
- Investigation of amino acid metabolism and its relation to cardiovascular inflammation.
Main Results:
- Oxidative stress promotes SMC calcification by increasing osteogenic transcription factors.
- Decreased bone factors and microRNAs accelerate vascular calcification.
- Immune activation and inflammation correlate with altered phenylalanine/tyrosine ratios in cardiovascular disease patients.
Conclusions:
- Endothelial dysfunction is a complex process involving oxidative stress, altered bone factor signaling, and amino acid metabolism.
- Targeting these molecular pathways may offer new therapeutic strategies for atherosclerosis and related conditions.
- Further research into these mechanisms is vital for advancing cardiovascular disease treatment.
Abstract:
Endothelial dysfunction is considered an early marker of atherosclerosis. Herein, we address the molecular mechanisms affecting endothelium remodeling in disease. Vascular calcification is highly prevalent in patients with ischemic cardiovascular disease, cerebrovascular disorder, and renal failure, being a common feature in aging, diabetes, dyslipidemia, abnormal valve biomechanics, end-stage renal disease and atherosclerosis, a major cause of mortality and morbidity. Oxidative stress promotes calcification of vascular smooth muscle cells (SMC) by increasing osteogenic transcription factors expression and activity in atherosclerotic plaques. Various markers of osteogenic differentiation are expressed by SMC in calcified atherosclerotic lesions. Interestingly, decreased levels of some bone factors and microRNAs accelerate vascular calcification and injured tissue regeneration. Another key player in endothelial remodeling is amino acids metabolism. Branched-chain amino acids are catabolized in several nonhepatic tissues including cardiac muscle. Immune activation and inflammation in cardiovascular disease patients associate with higher phenylalanine/tyrosine ratios. Understanding the whole process that underlies endothelium dysfunction is of paramount importance for the development of new therapeutic approaches.
