Abstract
The incidence of Alzheimer’s disease (AD) in people older 80 years old is 52%. Consequently, the predictive diagnostic of this neurodegenerative disease in long-liver is the actual goal of molecular medicine and gerontology.
The aim of the research is to compare saliva concentration of sirtuins of long-liver in early AD stage and people without neuropathology.
Methods. All long-liver were divided into 2 groups: «norm» (90–94 years old, n=14) and AD patients (90–95 years old, n=15). The «norm» group includes persons without neuropathology and other somatic diseases in the acute phase. Saliva concentration of Sirt1, Sirt3, Sirt5, Sirt6 was measured by enzyme immunoassay method.
Results. Saliva concentration of Sirt1, Sirt3 and Sirt6 AD patients was in 2.0, 3.7 and 3.0 times lower in comparison with corresponding parameter in the group «norm». Saliva concentration of Sirt5 of long-liver with Alzheimer’s disease and without neuropathology had no significant difference.
Conclusion. Saliva concentration of Sirt1, Sirt3, Sirt6 assessment in the saliva of long-liver can apply as one of the criteria of molecular early AD diagnostic.
