概括
这项研究将脊椎动物在农业化学和转基因作物 (GM) 安全性测试中的使用进行基准. 它发现每种活性成分约有1万只哺乳动物,每种转基因作物约有1200只脊椎动物,为动物减少目标建立了最低标准.
科学领域:
- 毒理学和生态毒理学
- 生物技术和基因工程 生物技术和基因工程
- 监管科学 监管科学
背景情况:
- 农业化学活性成分和转基因作物经过了广泛的毒理和安全评估,传统上依赖于体内 (动物) 测试.
- 农业化学部门正在努力减少动物试验,但不断变化的监管要求和数据包需求可能会矛盾地增加动物使用.
- 确定动物使用的明确基准对于跟踪进展和为减少这些领域的动物试验制定现实的目标至关重要.
研究的目的:
- 建立用于农业化学活性成分和转基因作物监管指南研究的脊椎动物数量的基准.
- 为农业化工行业内的有抱负的动物减少目标提供量化基础.
- 确定监管挑战,完善动物使用跟踪方法.

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
