What is Alpha‐lipoic acid ameliorates tauopathy‐induced oxidative stress, apoptosis, and behavioral deficits through the balance of DIAP1/DrICE ratio and redox homeostasis: Age is a determinant factor about?

Tauopathies belong to a heterogeneous class of neuronal diseases resulting in the metabolic disturbance. A disulfide natural compound of Alpha-Lipoic acid (ALA) has shown numerous pharmacologic, antioxidant, and neuroprotective activities under neuropathological conditions. The aim of this study was to investigate the neuroprotective effects of ALA on the tauopathyinduced oxidative disturbance and behavioral deficits. The transgenic Drosophila model of tauopathy induced by human tau R406W using GAL4/UAS system and effects of ALA (0.001, 0.005, and 0.025 % w/w of diet) on the neuropathology of tau in younger (20 days) and older (30 days) adults were investigated via biochemical, molecular, behavioral and in-situ tissue analyses. Expression of apoptosis-related proteins involving Drosophila Cyt-c-d (trigger of intrinsic apoptosis) and DrICE (effector caspase) were upregulated in both ages (20 and 30 days) and DIAP1 (caspase inhibitor) has reduced only in older model flies compared to the controls. Remarkably, all doses of ALA increased DIAP1 and glutathione (GSH) as well as reducing Cyt-c-d and lipid peroxidation (LPO) in the younger flies compared to the model flies. Moreover, the h
