Pepsin-digested chicken liver hydrolysates (CLHs), which are made from the byproducts of the poultry industry, are amino-acid based and of animal origin, and may be protective against the myocardial and renal damage induced by a high-fat diet (HFD). RESULTS: Our results showed that CLHs contain large quantities of anserine, taurine, and branched-chain amino acids (BCAAs), and supplementing the diet with CLHs reduced (P < 0.05) weight gain, liver weight, peri-renal fat mass / adipocyte-area sizes, serum total cholesterol (TC), aspartate aminotransferase (AST), and low-density lipoprotein cholesterol (LDLC) levels in HFD-fed mice but increased (P < 0.05) serum high-density lipoprotein cholesterol (HDLC) levels. By histological analyses, CLHs alleviated (P < 0.05) renal lipid deposition and fibrosis, as well as cardiac fibrosis and inflammation of HFD-fed mice. Meanwhile, increased (P < 0.05) inflammatory and fibrotic cytokines levels in the myocardia of the HFD-fed mice were downregulated (P < 0.05) by CLH supplementation. Regarding autophagy-related protein levels, protective effects of CLHs on the myocardia against HFD feeding may result from the early blockade of the autophagy pathway to prevent autophagosome accumulation. CONCLUSION: Functional CLHs could be a novel food ingredient as a cardio-renal protective agent against a high-fat dietary habit in a niche market. © 2020 Society of Chemical Industry. |
