Abstract

Oxidative stress and inflammation are two of the most critical factors implicated in carcinogenesis and other degenerative disorders. We have investigated how lunasin, a known anti-cancer seed peptide, affect these factors. This peptide inhibits linoleic acid oxidation and acts as 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenger. Furthermore, using LPS-stimulated RAW 264.7 macrophages, we have demonstrated that lunasin reduces, in a significant dose-dependent manner, the production of reactive oxygen species (ROS) by LPS-induced macrophages. Lunasin also inhibits the release of pro-inflammatory cytokines (tumor necrosis factor-α [TNF-α] and interleukine-6 [IL-6]). On the basis of these potent antioxidant and anti-inflammatory properties, we propose lunasin not only as a cancer preventive and therapeutic agent but also as an agent against other inflammatory-related disorders.
