Abstract:

Glycogen synthase kinase-3 (GSK-3) is a critical molecule in Alzheimer’s disease (AD) modulating two histopathological hallmarks of AD; Amyloid beta (Aβ) plaques and neurofibrillary tangles composed of aberrant hyper phosphorylation of tau protein. This study was performed to investigate the protective effect of apigenin, through inhibition of GSK-3 and the involvement of this kinase in BACE1 expression and hyper phosphorylation of tau protein in a rat AD model. 15 nM of aggregated amyloid beta 25-35 was microinjected into the left lateral ventricle. Apigenin (50 mg/kg) was administered orally 45 min before Aβ injection and continued daily for three weeks. Immunohistochemistry and western blot analysis showed that apigenin significantly reduced hyper phosphorylation of tau level in the hippocampus. Real time PCR analysis revealed a significant inhibition of mRNA level of β secretase (BACE1) and GSK-3β. Apigenin had no effect on the level of GSK-3α. The results demonstrate that apigenin has protective effects against amyloid beta 25-35 by decreasing the expression of GSK-3β with the consequence of lower the hyper phosphorylation of tau protein and suppression of BACE1 expression.
