Abstract
Alzheimer, a current neurodegenerative disorder has adverse effects on memory and behavior. β-Amyloid peptide accumulations are the hallmarks of Alzheimer. Dysfunction of autophagy and apoptosis is detected in Alzheimer's disease. The effect of Bowman-Birk inhibitor (BBI), purified from soybean, was investigated in autophagy and apoptosis in Alzheimer treatment. Treated-PC12 cells with 1000 nM HgCl2 induced amyloid β (Aβ) accumulation. Treatment of PC12 cells with 1000 nM HgCl 2 and then 500 μg/mL BBI could decrease the expression ratio of Bax/Bcl2 and increase the expression of beclin1, Bnip3, Atg5, and autophagy-related genes. These results indicated that BBI could inhibit Aβ accumulation by inducing autophagy, and also the neuroprotective effect was detected through decreasing apoptosis in the in vitro model of Alzheimer's disease. These results provided further evidence for the potential effectiveness of BBI in the treatment of Alzheimer's disease.
