Abstract:

The study aimed to analyze the genetic characteristic and expression of bovine FABP3 gene in transgenic mice,which will play a key role in culturing the breeds that produced higher yield and improved quality by transgenic method.Four FABP3 transgenic mice were used,G1 generation mice were obtained by 4 mating schmes.The genetic characteristic and expression of bovine FABP3 in heart,liver,kidney and skeletal muscle of transgenic mice were investigated in this study by RT-PCR and fluorescent in situ hybridization.The results of RT-PCR showed that bovine FABP3 gene could be identified in G0 transgenic mice by RT-PCR and propagated to G1 offspring,too.The positive rate was 68.4% in G1 and FABP3 gene expression levels in heart,skeletal muscle of transgenic mice were much higher than that of negative controls by real-time PCR.Furthermore,the fluorescent in situ hybridization results showed that bovine FABP3 gene could be expressed in the heart,liver,kidney and skeletal muscle in G0,G1 mice,and the expression in G0 was higher than that in G1 mice.This study suggests that bovine FABP3 gene has been successfully integrated and expressed in the mouse DNA,and expressed in G1 mice.The result would help us guide beef cattle molecular genetic breeding in the future.
