Ellagic acid reduces hepatic lipid contents through regulation of SIRT1 and AMPK in old rats.
Objective: Ellagic acid is used in traditional medicine for the treatment of lipid disorders. In this study, the effects of ellagic acid on key regulators of lipid metabolism, and histopathological alterations in aged liver were examined.
Methods: A total of 21 male Wistar rats were divided into three groups, including young control, old control, and old ellagic acid. After one month of treatment with ellagic acid, the expression levels of hepatic SIRT1, AMPK, SREBP-1c, PPAR-α, and phosphorylated AMPK (p-AMPK) were evaluated. The levels of several serum biochemical factors, and hepatic triglyceride, and cholesterol contents were assessed.
Results: Ellagic acid elevated the levels of SIRT1, p-AMPK, and PPAR-α and reduced SREBP-1c level in the liver of old rats. It decreased triglyceride and cholesterol contents in the aged liver and improved histopathological changes.
Conclusions: The results demonstrated that ellagic acid can exert protective effects against hepatic lipid metabolism disorders induced by ageing.
期刊介绍：
Archives of Physiology and Biochemistry: The Journal of Metabolic Diseases is an international peer-reviewed journal which has been relaunched to meet the increasing demand for integrated publication on molecular, biochemical and cellular aspects of metabolic diseases, as well as clinical and therapeutic strategies for their treatment. It publishes full-length original articles, rapid papers, reviews and mini-reviews on selected topics. It is the overall goal of the journal to disseminate novel approaches to an improved understanding of major metabolic disorders.
The scope encompasses all topics related to the molecular and cellular pathophysiology of metabolic diseases like obesity, type 2 diabetes and the metabolic syndrome, and their associated complications.
Clinical studies are considered as an integral part of the Journal and should be related to one of the following topics:
-Dysregulation of hormone receptors and signal transduction
-Contribution of gene variants and gene regulatory processes
-Impairment of intermediary metabolism at the cellular level
-Secretion and metabolism of peptides and other factors that mediate cellular crosstalk
-Therapeutic strategies for managing metabolic diseases
Special issues dedicated to topics in the field will be published regularly.
