Abstract

There are reports of improved redox outcomes due to consumption of Edible Bird’s nest (EBN). Many of the functional effects of EBN can be linked to its high amounts of antioxidants. Interestingly, dietary components with high antioxidants have shown promise in the prevention of aging and its related diseases like Alzheimer’s disease. In this study, the antioxidative potentials of EBN and its constituents, Lactoferrin (LF) and Ovotransferrin (OVF), were determined and protective effects against H2O2-induced toxicity on SH-SY5Y cells using MTT (3-(4,5-Dimethylthiazol-2-yl)- 2,5-Diphenyltetrazolium Bromide) assay and acridine orange and propidium iodide (AO/PI) staining with microscopy. Results showed that EBN and its constituent’s attenuated hydrogen peroxide (H2O2) induced cytotoxicity and decreased radical oxygen species (ROS) through increased scavenging activity. Furthermore, LF, OVF and EBN produced transcriptional changes in anti-oxidant related genes that tended towards neuroprotection as compared to H2O2 treated group. Overall, the results suggest that LF and OVF may produce synergistic or all-or-none anti-oxidative effects in EBN.
