Collagen (peptide) extracted from sturgeon swim bladder: Physicochemical characterization and protective effects on cyclophosphamide-induced premature ovarian failure in mice
Premature ovarian failure (POF) is a common female reproductive disorder, with oxidative damage playing a significant role in its development. Studies had demonstrated the beneficial antioxidant, anti-aging, and other biological properties of swim bladder collagen (peptide). In this study, acid extraction, water extraction, and enzymatic hydrolysis methods were used to extract collagen (peptide) from sturgeon ( Acipenser sinensis ) swim bladder, all of which exhibited significant antioxidant activity. Moreover, the effects observed in POF mice were enhanced, including an increasing in the number of growing ovarian follicles, regulation of serum hormone levels, and alterations in signaling pathways, as evidenced by the up-regulation of Phosphatidylinositol 3-kinase/Protein Kinase B (PI3K/Akt) and B cell lymphoma-2/ Bcl-associated x protein (Bcl-2/Bax) pathways, alongside the down-regulation of the mitogen-activated protein kinases (MAPK) signaling pathway. Sturgeon swim bladder collagen (peptide) could protect against cyclophosphamide-induced POF in mice, which could be very beneficial in the future advancement of health products.
