非人灵长类肿瘤模型研究进展(英文)

癌症是人类第二大致死的疾病。将体外细胞模型获得的癌症研究结果向临床转化过程中,动物活体实验是必不可少的一个环节。现在的肿瘤活体实验绝大部分采用啮齿类实验动物如小鼠和大鼠,这是因为它们具有个体小、繁殖迅速、遗传背景清楚、转基因技术成熟等优势。但是啮齿类和人的亲缘关系比较远,许多从啮齿类动物模型获得的研究结果不能在人体重现。非人灵长类动物在遗传进化、免疫、生理和代谢等诸多方面与人类高度近似,理论上更加适合癌症研究。本文对现有的非人灵长类肿瘤研究做一综述,主要集中介绍用化学和生物致癌剂在不同的非人灵长类动物诱导肿瘤的研究,为将来用非人灵长类动物研究人类癌症奠定基础。

Progress of non-human primate animal models of cancers

Cancer is the second leading disease causing human death.Pre-clinical in vivo studies are essential for translating in vitro laboratory research results into the clinic.Rodents,including the mouse and rat,have been widely used for pre-clinical studies due to their small size,clear genetic backgrounds,rapid propagation,and mature transgenic technologies.However,because rodents are evolutionarily distinct from humans,many pre-clinical research results using rodent models cannot be reproduced in the clinic.Non-human primates(NHPs)may be better animal models than rodents for human cancer research because NHPs and humans share greater similarity in regards to their genetic evolution,immune system,physiology and metabolism.This article reviews the latest progress of cancer research in NHPs by focusing on the carcinogenesis of different NHPs induced by chemical and biological carcinogens.Finally,future research directions for the use of NHPs in cancer research are discussed.
