ABSTRACT
Objective To investigate the expression of peroxisome proliferator-activated receptor γ (PPARγ) and uncoupling protein-1 (UCP-1) after sleeve gastrectomy in Zucker rats and to discuss the weight loss mechanisms.Metbods 30 male Zucker rats aged 10 weeks were randomly divided into 3 groupsthe operation group (10 rats),the sham operation group(10 rats) and the diet-pairing group (10 rats).The rats were decapitated to retrieve the retroperitoneal adipose.mRNA and protein expressions of PPARγ and UCP-1 were detected by RT-PCR and Western blot.Results As for the operation group,the weight decreased significantly after the operation compared to the other two groups((250±5.8) g,(370±10.0) g,(310±9.6) g,respectively,P<0.05).The expressions of PPARγ and UCP-1 gene of mRNA and protein were all significantly higher in the operation group (P<0.05).Conclusions SG can up-regulate the expressions of thermogenic gene PPARγand UCP-1 in adipose in Zucker rats,browning the white adipose tissue,which was one of the important mechanisms of weight loss.
