This article’s tone or style may not reflect the encyclopedic tone used on Wikipedia. See Wikipedia’s guide to writing better articles for suggestions. A major contributor to this article appears to have a close connection with its subject. This article may present fringe theories, without giving appropriate weight to the mainstream view, and explaining the responses to the fringe theories. Animal-derived foods that are high in fat and protein are generally AGE-rich and are prone to further AGE formation during cooking.
AGEs affect nearly every type of cell and molecule in the body and are thought to be one factor in aging and some age-related chronic diseases. AGEs contribute to the body’s burden of AGE, and are associated with diseases such as atherosclerosis and kidney disease. AGEs can also cause glycation of LDL which can promote its oxidation. Oxidized LDL is one of the major factors in the development of atherosclerosis. AGEs have been implicated in Alzheimer’s Disease, cardiovascular disease, and stroke. Inhibition of vascular dilation by interfering with nitric oxide.
Binding cells—including macrophage, endothelial, and mesangial—to induce the secretion of a variety of cytokines. Proteins are usually glycated through their lysine residues. Nevertheless, the resistance of extracellular matrix proteins to proteolysis renders their advanced glycation end products less conducive to being eliminated. Larger, extracellularly derived AGE proteins cannot pass through the basement membrane of the renal corpuscle and must first be degraded into AGE peptides and AGE free adducts. Large AGE proteins unable to enter the Bowman’s capsule are capable of binding to receptors on endothelial and mesangial cells and to the mesangial matrix. Although the only form suitable for urinary excretion, the breakdown products of AGE—that is, peptides and free adducts—are more aggressive than the AGE proteins from which they are derived, and they can perpetuate related pathology in diabetic patients, even after hyperglycemia has been brought under control. H oxidase through activation of RAGE and damage to mitochondrial proteins leading to mitochondrial dysfunction can also induce oxidative stress.
In diabetics who have an increased production of an AGE, kidney damage reduces the subsequent urinary removal of AGEs, forming a positive feedback loop that increases the rate of damage. 200-fold increase in AGE immunoreactivity from the meal with fructose. AGEs are the subject of ongoing research. There are three therapeutic approaches: preventing the formation of AGEs, breaking crosslinks after they are formed and preventing their negative effects.
Studies in rats and mice have found that natural phenols such as resveratrol and curcumin can prevent the negative effects of the AGEs. There is, however, no agent known that can break down the most common AGE, glucosepane, which appears 10 to 1,000 times more common in human tissue than any other cross-linking AGE. Some chemicals, on the other hand, like aminoguanidine, might limit the formation of AGEs by reacting with 3-deoxyglucosone.
