P62 AS A RISK DETERMINANT FOR METABOLIC SYNDROME

摘要

The p62 protein has been analyzed and identified as the significant contributor to several metabolic pathways that lead to metabolic syndrome, Alzheimer's Disease, and other related diseases. The absence of the p62 protein has a profound effect on the accumulation of tau protein, amyloid beta protein and an increase in blood insulin levels. The accumulation of tau protein and amyloid beta protein in neurological tissues is a hallmark of neurological metabolic diseases such as Alzheimer's Disease and related dementias. Moreover, increase blood insulin levels is an indicator of insulin resistance in mammals. Accordingly, the present invention provides a method for screening a mammal for metabolic disease comprising the step of detecting the absence of the p62 protein. The present invention also contemplates a method of screening a mammal for a metabolic syndrome comprising the steps of detecting the level of p62 protein in a metabolic pathway and determining whether the level of p62 protein falls below a threshold level. A pharmaceutical composition is also contemplated for therapeutic supplementation of a metabolic pathway, the pharmaceutical composition comprising a p62 protein or an amide, ester or salt thereof and a pharmaceutically effective carrier. Such pharmaceutical composition will have an inhibitory action on the phosphorylation, ubiquitination, accumulation of tau protein, an inhibitory effect on the accumulation of APP/amyloid beta and may operate to lower blood insulin levels.
