Abstract
본 발명에 따른 PEPCK 유전자를 과발현하는 형질전환 복제 개과 동물은 당뇨병 동물 모델로서, 제2형 당뇨병의 유전적 원인 규명과 진단 시약 및 치료제 개발에 이용될 수 있다.
Description
도 2는 H41IIE 세포에서 개의 PEPCK 프로모터의 활성을 웨스턴 블롯 분석으로 나타낸 것이다.
도 3은 본 발명에 따른 재조합 발현 벡터 pGL3_dPEPCK의 모식도를 나타낸 것이다.
도 4는 형질전환 공여핵원세포와 형질전환된 복제견의 유전체 DNA에 대한 PCR 분석 결과를 나타낸 것이다.
도 5는 일반광(a)과 형광(b)하에서 EGFP의 발현 유무를 확인한 결과를 나타낸 것이다(좌측견: 일반 복제견 보스턴 테이러, 우측견: 형질전환 복제견 비글).
도 6은 공여핵원, 복제자견과 대리모의 Microsatellite 분석 결과를 나타낸 것으로, 공여핵원과 DMP-108. DMP110 피크값이 같음을 알 수 있고, 이를 통해 공여핵원과 복제산자가 유전적으로 일치함을 밝혔다.
