Abstract

Active peptides have good effectiveness in controlling or preventing many diseases. Compound active peptides (CAP) obtained from animal, plant, and sea food proteins were used in this study to explore their effects on antioxidation, anti-inflammation, and antihyperglycemia and . The results demonstrated that 10 g/mL CAP could increase cell viability ( < 0.05) and decrease reactive oxygen species (ROS) levels and cell apoptosis ( < 0.05) when WRL68 cells were induced by HO for 6 h. Moreover, incubation with 20 g/mL CAP for 6 h significantly increased cell viability and Bcl-2 expression level ( < 0.05) and decreased expression levels of IL-6, IL-8, TNF-, Bax, and Caspase 3 and the ratio of Bax/Bcl-2 ( < 0.05) when swine jejunal epithelial cells (IPEC-J2) were induced by deoxynivalenol (DON). In addition, adding CAP individually or combined with Liuweidihuang pills (LDP, Chinese medicine) and low-dose glibenclamide could lower blood glucose levels in alloxan-induced hyperglycemic model mice. These results suggested that CAP was probably a beneficial ingredient for alleviating HO-induced oxidative stress and DON-induced cell inflammation and apoptosis and preventing hyperglycemia.
