유전자 변형 작물은 생산성 측면에서 많은 장점이 있지만 이를 섭취할 경우 잠재적인 위험 요소들에 의해 많은 문제가 대두대고 있다. 본 연구는 저항성유전자를 이입한 배추에서 Profillin, Tubulin-${alpha}$ (Tub-${alpha}1$), Heat-shock protein (Bchsp 17.6) and Ubiquitin conjugating enzyme (UBE)의 발현과 이를 30일간 섭취한 마우스에서 ${eta}$-actin(${eta}$-act), ${eta}$-2-microglobulin (B2m), Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and ${eta}$-glucuronidase (Gus)의 발현 정도를 RT-PCR을 통해 알아보았다. 실험 결과 저항성유전자를 이입한 배추와 그렇지 않은 배추의 유전자 발현 패턴은 큰 차이를 보이지 앓았으며, 이를 섭취한 마우스 장기에서도 발현에 따른 큰 차이는 나타나지 않았다.
We used RT-PCR to measure housekeeping gene expression in mice fed GM and non-GM cabbage, in an effort to evaluate the risk of GM food to humans. After normalization of housekeeping gene levels, highly uniform expression may be seen in many organisms during various stages of development and under different environmental conditions. We assessed the expression of four genes in Chinese cabbage; these were Profilin, Tubulin-alpha (Tub-1), Heat-shock protein (Bchsp 17.6), and Ubiquitin conjugating enzyme (UBE). We measured the expression of four well-known housekeeping genes in mice: ${eta}$-actin, (${eta}$-act), ${eta}$-2-microglobulin(B2m), Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and ${eta}$-glucuronidase (Gus). Gene expression was measured in liver, stomach, small intestine, large intestine, kidney, and spleen of mice fed GM or non-GM cabbage. No significant expression differences were found.
