Researchers Identify Molecule With Anti-Aging Effects On Vascular System
Table of Contents
A molecule produced during fasting or calorie restriction has anti-aging effects on the vascular system, which could reduce the occurrence and severity of human diseases related to blood vessels, such as cardiovascular disease, according to a study led by Georgia State University. In this study, the research team explores the link between calorie restriction (eating less or fasting) and delaying aging, which is unknown and has been poorly studied. The findings are published in the journal Molecular Cell.
The researchers identified an important, small molecule that is produced during fasting or calorie restriction conditions. The molecule, β-Hydroxybutyrate, is one type of a ketone body, or a water-soluble molecule that contains a ketone group and is produced by the liver from fatty acids during periods of low food intake, carbohydrate restrictive diets, starvation and prolonged intense exercise. Senescent cells can no longer multiple and divide.
The researchers found β-Hydroxybutyrate can promote cell division and prevent these cells from becoming old. Because this molecule is produced during calorie restriction or fasting, when people overeat or become obese this molecule is possibly suppressed, which would accelerate aging.
