Abstract
Oxidative stress plays a key role in neuronal cell damage, which is associated with neurodegenerative disease. Recently, attention has been paid to searching for natural source that can protect neuronal cell damage against oxidative stress. Although there are evidences that dietary n-3 fatty acid has beneficial effects, it has been focused on fish oil. Alphalinolenic acid (ALA) is also promising n-3 fatty acids in vegetable oils with health beneficial roles. Perilla oil (PO) contains the largest proportion of ALA. However, the study on molecular mechanism between ALA and hydrogen peroxide (H2O2)- induced neuronal apoptosis has not been studied yet. The aim of present study is to investigate the neuro-protective effects of PO and ALA against H2O2-induced oxidative stress in SH-SY5Y neuronal cells. Our result showed that treatment with PO and ALA significantly attenuated H2O2-induced cell death, indicating that PO and ALA potently blocks H2O2- induced neuronal apoptosis. Furthermore, cleaved-poly ADP ribose polymerase, cleaved caspase-3 and -9 activations were decreased in the presence of PO and ALA and H2O2-mediated down-regulated Bax/Bcl-2 ratio was blocked after treatment with PO and ALA. Taken together, the protective role of PO from neuronal cell damage is mainly attributed to ALA. The present study suggests that PO and ALA may play potent therapeutic agents for neurodegenerative disorders such as Alzheimer’s disease.
Biography

Ah Young Lee is a PhD candidate in Food Science and Nutrition at Pusan National University of Korea, and conducts study under the guidance of Professor Eun Ju Cho.
