摘要: Visfatin, like insulin, induces phosphorylation of signal transduction proteins that operatate downstream of the insulin receptor. The present study is focused on detecting deletion of visfatin gene and analyzing its effect on growth traits in six Chinese cattle breeds (Nangyang, Luxi, Qinchuan, Jiaxian Red, Grassland Red, and Chinese Holstein) using DNA sequencing, PCR-SSCP and PCR-RFLP methods. For the first time, a 6-bp deletion of visfatin was described and two alleles were revealed: W and D. The χ2-test analysis demonstrated that all breeds were in agreement with Hardy-Weinberg equilibrium (P>0.05). The associations of the novel 6-bp deletion of visfatin gene with growth traits of Nanyang cattle at 6-, 12-, 18-, and 24-mon-old were analyzed. Birth weight, 12- and 24-mon-old cattle with genotype WW had greater birth weight and average daily gain than genotype WD (P<0.01 or P<0.05). These results suggest that the deletion may influence the birth weight and bodyweight in 12 mon-old cattle.
