title: Predictive association of copper metabolism proteins with Alzheimer's disease and Parkinson's disease: a preliminary perspective.
abstract: Neurodegenerative diseases, Alzheimer's disease (AD) and Parkinson's disease (PD), constitute a major worldwide health problem. Several hypothesis have been put forth to elucidate the basis of onset and pathogenesis of AD and PD; however, till date, none of these seems to clearly elucidate the complex pathoetiology of these disorders. Notably, copper dyshomeostasis has been shown to underlie the pathophysiology of several neurodegenerative diseases including AD and PD. Numerous studies have concluded beyond doubt that imbalance in copper homeostatic mechanisms in conjunction with aging causes an acceleration in the copper toxicity elicited oxidative stress, which is detrimental to the central nervous system. Amyloid precursor protein and α-synuclein protein involved in AD and PD are copper binding proteins, respectively. In this review, we have discussed the possible association of copper metabolism proteins with AD and PD along with briefly outlining the expanding proportion of "copper interactome" in human biology. Using network biology, we found that copper metabolism proteins, superoxide dismutase 1 and ceruloplasmin may represent direct and indirect link with AD and PD, respectively.
