Anti-skin-aging effect of fish gelatin from Cynoscion acoupa by maintaining collagen matrix homeostasis on D-galactose induced aging mice

引用

Food Science and Human Wellness 2024年

作者： Jianxin Tian Jingru Liao Biluan Zhong Pan Li Xiaoqian Liu Bing Du Guanzhan Fish Maw nutrition and Security research Center college of Food Science South China Agricultural University Guangdong Shenzhiyuan health Technology co. ltd.

Delaying skin-aging through diet is a hot research topic in recent years， but the anti-aging effects of fish gelatin and related mechanisms are not well understood. In this study， we prepared edible fish gelatin from the swim bladder of Cynoscion acoupa using three different processing methods， namely dried (DCM)， soaked (SCM) and instanted (ICM)， to investigate its anti-aging effects and mechanisms on D-galactose induced skin aging in mice， as well as its effects on the gut microbiota. The results demonstrated that fish gelatin significantly increased water content， collagen， hyaluronic acid (HA) and hyaluronic acid (HYP) content， and skin integrity of mice skin， as well as enhanced the antioxidative ability and anti-inflammatory capacity of the skin. In terms of protein and mRNA expression levels in skin tissue， CMs treated with different treatments can up-regulate the expression of EGFR and TIMP1， down-regulating the expression of MMP1 and MMP3， and increase the expression of coL3A1 and coL1A2. CMs attenuated the D-galactose-mediated inhibition collagen expression by stimulating the TGF-β/Smad signaling pathway， thereby maintaining collagen matrix homeostasis. In addition， we revealed that CMs reversed gut micribiota by increase the abundance of intestinal flora. In conclusion， we demonstrated that CMs， especially for ICM， as an effective dietary supplement， have potential anti-aging and skin health benefits.

Ltd complete Feed Solutions

Standardized ileal digestibility coefficients (SIDC) of nitrogen (N) and amino acids (AA) in two protein sources (soybean meal [SBM] and canola meal [CM]) were investigated at six broiler ages (d 7, 14, 21, 28, 35, and 42). Two assay diets were formulated to contain either SBM (413 g/kg) or CM (553 g/kg) as the sole dietary AA source. Titanium dioxide (5 g/kg) was added as an indigestible marker. A total of 696 male broilers at 1 d old were allotted to 12 replicate cages per age group. Each assay diet was offered to birds for 4 d prior to the ileal digesta collection on d 7 (14 birds/cage), 14 (12 birds/cage), 21 (10 birds/cage), 28 (8 birds/cage), 35 (8 birds/cage) and 42 (6 birds/cage), respectively. The apparent digestibility coefficients were standardized using age-specific basal endogenous AA flows. In the SBM group, though the SIDC of N tended to be influenced (quadratic; P=0.075) by age, no linear or quadratic response of age effect was observed on the average SIDC of indispensable (IAA) and total AA (TAA). An age effect (quadratic; Pcorded at d 7, followed by a decrease from d 14 to 28, which increased beyond d 35.
