Abstract

Graphical abstract: Highlights: Milk-derived peptides performed inhibitory effect on intracellular ROS. Milk-derived peptides enhanced the SOD activity in HFF-1 cells. Milk-derived peptides realized UVB radiation damage repair. Anti-photoaging related peptides were identified. Abstract: Long-term exposure to UVB can trigger acute inflammation of the skin and lead to skin photoaging. To scrutinize the anti-photoaging functions of peptides obtained from milk, the physicochemical including molecular weight and amino acid compositions were first analyzed. Totally 267 peptides were screened out and identified by PEAKS X software, and then evaluated through Peptide Ranker and BIOPEP-UMW. Six peptides with the highest antioxidant ability and relative abundance were selected. This study was then conducted in UVB-damaged human foreskin fibroblasts with proadministration of peptides. The results indicated that at concentrations of 0.08–0.10 mg/mL, milk-derived peptides could realize a damage prevention effect through inhibiting the generation of reactive oxygen species (ROS) and lipid peroxidation malondialdehyde (MDA). Also, these peptides were found to promote the photoaging related enzyme activities of superoxide dismutase (SOD) and catalase (CAT), while to block the production of matrix metalloproteinases-1. Through this study, we found that milk-derived peptide mixture is effective in preventing photoaging damage. Milk-derived peptides found in this study could serve as raw materials for future development of antioxidant functional foods.
