Nitric oxide inhibits insulin-degrading enzyme activity and function through S-nitrosylation.
Insulin-degrading enzyme (IDE) is responsible for the degradation of a number of hormones and peptides, including insulin and amyloid beta (Abeta). Genetic studies have linked IDE to both type 2 diabetes and Alzheimer's disease. Despite its potential importance in these diseases, relatively little is known about the factors that regulate the activity and function of IDE. Protein S-nitrosylation...
متن کاملInsulin, insulin-degrading enzyme and amyloid-beta peptide in Alzheimer's disease: review and hypothesis.
Clinical and epidemiological studies have found that type 2 diabetes, and hyperinsulinaemia, increased the risk of developing Alzheimer's disease (AD) in the elderly. The link between hyperinsulinaemia and AD may be insulin-degrading enzyme (IDE). This enzyme degrades both insulin and amylin, peptides related to the pathology of type 2 diabetes, along with amyloid-beta peptide (Abeta), a short ...
متن کاملInsulin-degrading enzyme in brain microvessels: proteolysis of amyloid {beta} vasculotropic variants and reduced activity in cerebral amyloid angiopathy.
The accumulation of amyloid beta (Abeta) in the walls of small vessels in the cerebral cortex is associated with diseases characterized by dementia or stroke. These include Alzheimer's disease, Down syndrome, and sporadic and hereditary cerebral amyloid angiopathies (CAAs) related to mutations within the Abeta sequence. A higher tendency of Abeta to aggregate, a defective clearance to the syste...
متن کاملAbeta-degrading enzymes: modulators of Alzheimer's disease pathogenesis and targets for therapeutic intervention.
The accumulation of Abeta (amyloid beta-protein) peptides in the brain is a pathological hallmark of all forms of AD (Alzheimer's disease) and reducing Abeta levels can prevent or reverse cognitive deficits in mouse models of the disease. Abeta is produced continuously and its concentration is determined in part by the activities of several degradative enzymes, including NEP (neprilysin), IDE (...
متن کاملInsulin-degrading enzyme as a downstream target of insulin receptor signaling cascade: implications for Alzheimer's disease intervention.
Insulin-degrading enzyme (IDE) is one of the proteins that has been demonstrated to play a key role in degrading beta-amyloid (Abeta) monomer in vitro and in vivo, raising the possibility of upregulating IDE as an approach to reduce Abeta. Little is known, however, about the cellular and molecular regulation of IDE protein. Because one of the main functions of IDE is to degrade insulin, we hypo...
