AB  - Leptin is encoded by <I>obsese</I> gene is an adipocyte-secreted 
  cytokine. The main function of it is to regulate the balance of energy through 
  the signal transduction pathway and it has a strong relationship with the function 
  of reproduction, organism immune. PCR-SSCP and SYBGREEN Q-PCR was used to analyze 
  the polymorphism of <I>leptin</I> gene and expression difference in 139 samples 
  of Luxi (LX) cattle breeds. The association of variations of <I>leptin</I> gene 
  with growth traits was analyzed. Some indexes of the individuals with genotype 
  BB were higher than that with genotype AA and AB in LX breed such as the indexes 
  of body length, heart length, body weight, hucklebone width, body height. Leptin 
  express high in the white adipose tissue but there is little expression in the 
  organ or the tissue such as heart, liver, kidney, spleen, lung and muscle. These 
  results may be applied to Marker-Assisted Selection (MAS) of Chinese LX cattle 
  breeds improving the economic traits of cattle.
