Abstract:Objective. This study aimed to delve into the antioxidant potential of small-molecule peptides derived from Lactiplantibacillus plantarum SCS2 (L. plantarum SCS2), targeting hydrogen peroxide- (H2O2-) induced rat insulinoma (INS-1) cells. Methods. INS-1 cells were pretreated with small-molecule peptides of distinct molecular weights, specifically P1 (≤1 kDa), P2 (1–5 kDa), and P3 (5–10 kDa), which were isolated from L. plantarum SCS2, followed by H2O2 to induce oxidative damage in INS-1 cells. The oxidative st… Show more
