title: [UCPs and PPARgamma2 mRNA in diet induced obesity resistant rats].
abstract: OBJECTIVE
  To explore the expression of uncoupling proteins (UCP) and peroxisome proliferator activated receptorgamma2 (PPARgamma2) mRNA in white adipose of high-fat diet induced obesity resistant rats.
  
  
  METHODS
  Thirty-six female SD rats were randomly divided into high-fat diet group (n = 27) and chow fed control group (n = 9), and given either high-fat diet or chow for thirteen weeks. Then the high-fat diet group was subdivided into Dietary Induced Obesity (DIO) and Dietary Induced Obesity Resistant (DIO-R) group according to the final body weight. Basic parameters, fasting blood glucose (FBG), blood lipid levels were measured and compared. Reverse transcription-polymerase chain reaction (RT-PCR) was used to measure the expression of UCP2, UCP3, and PPARgamma2 mRNA in white adipose.
  
  
  RESULTS
  Adipose deposits, body fat percent, TC, and TG conceration of both DIO-R and DIO groups were significantly higher than those in control group, while body weight, body fat percent and TG level were significantly lower in DIO-R than DIO rats. The expression of UCP2 and UCP3 mRNA in white adipose of DIO-R rats were significantly higher than those of DIO and control group. The expression of PPARgamma2 mRNA in white adipose of DIO-R group was significantly lower than that in DIO group.
  
  
  CONCLUSIONS
  High-fat diet induced obesity resistance were closely associated with the increased UCP2, UCP3, and decreased PPARgamma2 mRNA in white adipose.
