摘要:

分别用含有转cry1Ab/Ac基因水稻和亲本水稻的饲料饲喂野生褐家鼠,旨在检测外源cry1Ab/Ac基因和蛋白在褐家鼠雌鼠雄鼠空肠、回肠、盲肠中的残留情况。检测结果显示,饲喂转基因水稻50 d和110 d的雌雄褐家鼠肠道3个部位中没有检测到cry1Ab/Ac基因残留,在体外消化实验中过量外源基因全长及片段在4 h后开始逐步降解,约12 h全部降解。3个肠道部位提取的蛋白进行ELISA和Western blot分析,结果显示肠道内容物中无Cry1Ab/Ac蛋白残留。因此外源基因和蛋白不会在饲喂了转基因水稻的野生褐家鼠肠道中残留。

Abstract:

The exogenous cry1Ab/Ac gene and protein residues in the jejunum, ileum, cecum of Rattus norvegicus feeding transgenic rice and parent rice were detected. The testing results showed that there were no residues of cry1Ab/Ac gene in 3 intestinal parts of R. norvegicus fed transgenic rice for 50 and 110 d, and overall length or fragment of exogenous cry1Ab/Ac gene gradually degraded after 4 h, and completely at 12 h in vitro. No residues of Cry1Ab/Ac protein were detected in contents of the above 3 parts of R. norvegicus using ELISA and Western blot method. In conclusion, the exogenous gene and protein of the transgenic rice were not remained in the intestines of R. norvegicus.
