Alzheimer’s disease (AD) is an accelerating neurodegenerative disorder. Dysfunction of mitochondria and oxidative stress contributes to the pathogenesis of AD. Sirtuins play a role in this pathway and can be a potential marker to study neurodegenerative changes."

“This study evaluated serum levels of all seven sirtuin (SIRT1–SIRT7) proteins in three study groups: AD, mild cognitive impairment (MCI) and geriatric control (GC) by surface plasmon resonance (SPR) technique.”

“Out of seven sirtuins, serum SIRT1, SIRT3 and SIRT6 levels were significantly decreased in AD compared to MCI and GC. The concentration declined significantly with the disease progression. This is the first report of estimation of all seven serum sirtuins and the clinical relevance of SIRT3 and SIRT6 as serum protein markers for AD.”
