성장관련 유전자를 이용한 형질전화토끼의 생산

Transgenic rabbits were produced by DNA microinjection using growth hormone receptor (GHR) and IGF-1 receptor (IGF-1R) genes. Overall efficiencies for production of transgenic rabbits were 3.2% and 3.1% in GHR and IGF-1R genes, respectively. Founder rabbits transmitted transgenes to their progenies through medelian fashion. Growth rate in GHR and ICF-1R transgenic rabbits was faster than non-transgenic rabbits. Transgenic rabbits grew larger (25% and 15% increase in body weight of GHR and IGF-1R transgenic rabbits, respectively) than non-transgenic rabbits and organ weight of transgenic rabbits increased, suggesting that GHR and IGF-1 genes affects growth rates in transgenic rabbits.
