摘要

The current research aimed to explore the impact of (-)-hydroxycitric acid (HCA) on fat metabolism and investigate whether this action of (-)-HCA was associated with modulation of glucose-6-phosphote isomerase (GPI) expression in chicken embryos. We constructed a recombinant plasmid (sh2-GPI) to inhibit GPI expression, and then embryos were treated with (-)-HCA. Results showed that (-)-HCA reduced lipid droplet accumulation, triglyceride content, and lipogenesis factors mRNA level and increased lipolysis factors mRNA expression, while this effect caused by (-)-HCA was markedly reversed when the chicken embryos were pretreated with sh2-GPI. (-)-HCA increased phospho (p)-acetyl-CoA carboxylase, enoyl-CoA hydratase short chain-I, carnitine palmitoyl transferase 1A, p-AMP-activated protein kinase, and peroxisome proliferators-activated receptor alpha protein expression, and this action of (-)-HCA also dispelled when the chicken embryos were pretreated with sh2-GPI. These data demonstrated that (-)-HCA decreased fat deposition via activation of the AMPK pathway, and the fat-reduction action of (-)-HCA was due to the increasing of GPI expression in chicken embryos.
