项目摘要

This genetic toxicology testing contract has supported the overall mission of NTP to provide detailed toxicological profiles, including potential for carcinogenicity, of compounds of interest for over 30 years. Assessment of genetic damage, an important factor in the initiation and development of cancer as well as neurodegenerative diseases such as ALS, neurological conditions such as autism, aging processes, birth defects such as Down syndrome, mitochondrial diseases, and other adverse human health effects, is a critical component of any in-depth toxicological profile of a chemical or product. An important complication in assessing the impact of environmentally induced genetic damage is that genetic damage induced early in life, even prior to birth, may not manifest as an adverse health effect until decades later, during adulthood. This delay in manifestation, along with a lack of any immediate symptoms of genetic damage, makes it difficult to link early life exposures that cause genetic damage with adult disease. Because of the importance in understanding potential for induced genetic damage, a detailed characterization of the genotoxic potential of new pharmaceutical and pesticide products, as well as other types of products for which human exposure is a concern, is required by regulatory agencies such as the Food and Drug Administration and the Environmental Protection Agency prior to approval for use. This Genetic Toxicity Testing contract provides information to the NTP on various types of exposure-related genetic damage using universally accepted standard testing protocols as well as innovative approaches, when necessary and applicable, to supplement the information obtained from standard tests. Testing systems employed under this contract include both in vitro (animal and human cell-based, and bacterial) and in vivo (rats and mice) assays. The capabilities of this genetic toxicity testing contract are continuously updated to remain current with the latest scientific approaches in the field and consistent with international guidelines for conducting these kinds of tests. The field is currently undergoing rapid evolution with the many dramatic changes in technological capabilities that are occurring today.

30 多年来，这份遗传毒理学测试合同一直支持 NTP 的总体使命，即提供感兴趣的化合物的详细毒理学特征，包括潜在的致癌性。评估遗传损伤，这是癌症发生和发展的一个重要因素，以及神经退行性疾病（如 ALS）、神经系统疾病（如自闭症）、衰老过程、出生缺陷（如唐氏综合症）、线粒体疾病以及其他不利的人类健康影响，是化学品或产品的任何深入毒理学特征的关键组成部分。在评估环境引起的遗传损伤的影响时，一个重要的复杂问题是，生命早期（甚至出生前）引起的遗传损伤可能要到几十年后的成年时期才会表现出对健康的不利影响。这种表现的延迟，加上缺乏任何遗传损伤的直接症状，使得很难将导致遗传损伤的早期暴露与成人疾病联系起来。由于了解诱发遗传损伤的可能性非常重要，因此食品和药物管理局等监管机构要求对新药品和农药产品以及其他类型的人类接触问题产品的遗传毒性潜力进行详细表征。在批准使用之前，请先征得药物管理局和环境保护局的同意。该基因毒性测试合同使用普遍接受的标准测试方案以及创新方法（在必要和适用时）向 NTP 提供有关各种类型的暴露相关基因损伤的信息，以补充从标准测试中获得的信息。该合同下使用的测试系统包括体外（动物和人类细胞以及细菌）和体内（大鼠和小鼠）测定。该遗传毒性测试合同的功能不断更新，以与该领域最新的科学方法保持同步，并与进行此类测试的国际准则保持一致。该领域目前正在快速发展，技术能力发生了许多巨大的变化。
