Abstract

Milk contains various bioactive components with osteoanabolic properties. This study investigates the comparative effect of the whey-derived antioxidative (YVEEL) and angiotensin-converting enzyme inhibitory (YLLF) bioactive peptides on bone remodelling in ovariectomised (OVX) osteoporotic rat model. OVX animals were administered with antioxidative (AO) (500 μg kg−1 day−1) and angiotensin-converting enzyme inhibitory (ACE inhibitory) (50 μg kg−1 day−1) peptides for eight weeks. Trabecular microarchitectural parameters of femoral and tibiae bone were determined using micro-CT scan. Bone formation, resorption, turnover markers (ALP, RANKL, OCN) and inflammatory cytokines (TNF-α, TGF-β, IFN-γ) were determined by ELISA. Both AO and ACE inhibitory peptides inhibited the increase in bone turnover and inflammatory cytokines while increased the bone formation markers. The altered morphometric parameters of femoral and tibiae bones due to OVX were strikingly attenuated by the peptide administration. The results indicated that AO peptide exerts more osteoprotective potential than ACE inhibitory peptide by suppressing inflammatory status and enhancing bone formation markers.
