Adenovirus Virus Expressing Myostatin- Somatostatin Fusing Gene Promote the Growth Rate of the Mice

Abstract

Myostatin (MSTN) and somatostatin (SST) are negative regulate factors in the animals. Immunized animals with these proteins induce the related immune response, which could neutralize the normal inhibitory effects of these proteins. Since adenovirus was the mostly wildly used vector for delivering vaccine antigen, here, a recombinant adenovirus expressing MSTN-SST were constructed and mice were inoculated with the recombinant adenovirus. As our predicted, immunization with this adenovirus one time or two times were all induced the specific immune response and resulting in an improve growth rate and muscle mass. And boost immunization improved the effect of the immunization. Accordingly, adenovirus can be used as a vector for deliver myostatin and somatostatin gene, so as to increase animal growth rate and muscle mass of the animals.
