SHIP2: A “NEW” Insulin Pathway Target for Aging Research

2014

Strong evidence suggests that systemic inflammation and central adiposity contribute to and perpetuate metabolic syndrome. All of these alterations predispose individuals to type 2 diabetes mellitus (T2DM), cardiovascular disease, as well as Alzheimer's disease (AD), all characterized by chronic inflammatory status. On the other hand, extensive abnormalities in insulin and insulin-like growth factor I (IGF-I) and IGF-II signaling mechanisms in brains with AD have been demonstrated, suggesting that AD could be a third form of diabetes. The Src homology domain-containing inositol 5-phosphatase 2 (SHIP2) has an important role in the insulin pathway because its over-expression causes impairment…

Can Alzheimer disease be a form of type 3 diabetes?

2012

Alzheimer disease (AD) and metabolic syndrome are two highly prevalent pathological conditions of Western society due to incorrect diet, lifestyle, and vascular risk factors. Recent data have suggested metabolic syndrome as an independent risk factor for AD and pre-AD syndrome. Furthermore, biological plausibility for this relationship has been framed within the “metabolic cognitive syndrome” concept. Due to the increasing aging of populations, prevalence of AD in Western industrialized countries will rise in the near future. Thus, new knowledge in the area of molecular biology and epigenetics will probably help to make an early molecular diagnosis of dementia. An association between metabo…

Age-related Diseases: Key Role of Insulin Resistance for the Association Between Type II Diabetes and Alzheimer’s Disease

2012

Background: Alzheimer’s disease (AD) and Type 2 diabetes mellitus (T2DM) present many relationships. Insulin resistance (IR) plays a key role in neuronal degeneration and death. Reduced energy makes neurons more sensible to oxidation causing mitochondrial damages. Moreover AD brain has lower insulin utilization, reduced expression of its receptors and of IGF 1 and 2, all necessary for neuronal survival and learning and memory processes. Hyperinsulinemia is correlated with increase of hyerphosphorilated tau-protein. SHIP2, a phosphatase, is an antagonist of PI3K. Since the PI3K plays a key role in the biological effects of insulin, its attenuation could be associated with IR in T2DM. Methods…
