Oxidative damage to the constituents of the eye lens is a major mechanism in the initiation and development of cataract. Lunasin, a 43-amino acids chemoprevention peptide, has been proved to possess potent anti-oxidative activity other than its established anticancer activities. Herein, we explored whether lunasin has preventative effects on d-galactose-induced experimental cataract in rat. After modeling, SD rats were administrated by instillation, 80 μM of lunasin eye drops to each eye thrice daily and consecutively for 30 days. As a result, lunasin treatment effectively inhibited the progression of d-galactose-induced experimental cataract, and protected the lenses of rats from oxidative damage and attenuated the lipid peroxidation through up-regulation of antioxidant enzymes, and inhibited the activation of polyol pathway by decreasing AR activity. Additionally, in vitro studies proved that lunasin treatment could protect human lens epithelial cells (hLECs) against d-galactose induced cell damage and apoptosis, and up-regulate antioxidant enzymes.
