Antihyperlipidemic effect of bread fortified with potato peel powder against Triton X-100-induced hyperlipidemia in male albino rats

Abstract

The present investigation aimed to improve the nutritional and healthy values and evaluate the influence of bread fortified with dried potato peels (BPP) on Triton X-100-induced hyperlipidemia in male albino rats. The findings demonstrated that BPP lowered hepatic triglycerides and total cholesterol while increasing high-density lipoprotein (HDL-C). BPP exhibited potential lipid-lowering and hepatoprotective actions that were generated by the reduction of oxidative damage and preservation of the non-enzymatic and enzymatic antioxidant systems compromised by hyperlipidemic condition. Furthermore, BPP considerably enhanced the mRNA expression of AMPKα (AMP-activated protein kinase-alpha), suppressed the expression of fatty acid synthase (FAS) and acetyl-CoA carboxylase alpha (ACCα), and decreased the mRNA expression of the adipogenic transcription factor SREBP-1c (sterol regulatory element-binding protein-1c), which are essential regulators of hepatocyte lipid metabolism. A histopathological assessment of the liver confirmed the results. In conclusion, this investigation revealed a positive impact of bread fortified with BPP therapy in preventing hyperlipidemia.
