Toxicological research faces the challenge of integrating knowledge from diverse fields and novel technological developments generally in the biological and medical sciences. We discuss herein the fact that the multiple facets of cancer research, including discovery related to mechanisms, treatment and diagnosis, overlap many up and coming interest areas in toxicology, including the need for improved methods and analysis tools. Common to both disciplines, in vitro and in silico methods serve as alternative investigation routes to animal studies. Knowledge on cancer development helps in understanding the relevance of chemical toxicity studies in cell models, and many bioinformatics-based cancer biomarker discovery tools are also applicable to computational toxicology. Robotics-aided, cell-based, high-throughput screening, microscale immunostaining techniques and gene expression profiling analyses are common tools in cancer research, and when sequentially combined, form a tiered approach to structured safety evaluation of thousands of environmental agents, novel chemicals or engineered nanomaterials. Comprehensive tumour data collections in databases have been translated into clinically useful data, and this concept serves as template for computer-driven evaluation of toxicity data into meaningful results. Future 'cancer research-inspired knowledge management' of toxicological data will aid the translation of basic discovery results and chemicals- and materials-testing data to information relevant to human health and environmental safety.
毒理学研究面临着整合来自不同领域和新兴技术发展的知识的挑战,这些知识通常涉及生物和医学科学。我们在此讨论了这样一个事实,即癌症研究的多个方面,包括与机制、治疗和诊断相关的发现,与毒理学中许多即将到来的热点领域重叠,包括对改进方法和分析工具的需求。体外和计算方法是动物研究的替代研究途径,这在两个学科中是共同的。癌症发展的知识有助于理解化学毒性研究在细胞模型中的相关性,许多基于生物信息学的癌症生物标志物发现工具也适用于计算毒理学。机器人辅助、基于细胞的高通量筛选、微尺度免疫染色技术和基因表达谱分析是癌症研究中的常用工具,当它们依次组合时,就形成了一种针对数千种环境剂、新型化学物质或工程纳米材料进行结构化安全评估的分层方法。数据库中的综合肿瘤数据收集已经转化为临床有用的数据,这一概念为计算机驱动的毒性数据评估提供了有意义的结果提供了模板。未来“癌症研究启发的毒理学数据知识管理”将有助于将基础发现结果和化学品及材料测试数据转化为与人类健康和环境安全相关的信息。
