The Expression Characteristic of MTP Gene and the Effect of Overfeeding on the Expression of MTP in the Various Tissues and Different Developmental Stages in Landes Geese

With Landes Goose as experimental materials, we adopted the RT-PCR method to research the expression characteristic of MTP gene in liver, intestine, brain, Pectoralis muscle, Hamstring muscles, Skin+subcutaneous adipose tissue , Abdominal adipose tissue and heart at 5 growth points , including 1 , 10 , 13, 14 , and 16 weeks and also the effect of overfeeding on MTP gene expression in liver and intestine was researched. The results indicated : the expression of MTP gene was detected only in the small intestine at 1 weeks; except in the liver and intestinal tissues, MTP gene was firstly discovered in the brain tissues in the 10 weeks old geese; the expression level of MTP gene in liver and intesine increased dependent with the increase of week age (P <; 0.05); the expression of MTP gene was intestine> liver at 1 to 13 week age, intestine<; liver at 13 to 16 week age reversely; overfeeding induced the decrease of expression of MTP gene in the liver, and the increase in the intestine.Therefore, We inferred MTP gene was a very important of the fat deposition and transfer in Landes geese.
