流行病学研究已经确定了许多环境因素,这些因素似乎显著增加了人类患癌症的风险。通过分析长期暴露于20种已知或可疑人类致癌物之一的小鼠的肿瘤基因组,我们发现大多数药物不会产生明显的突变特征或增加突变负担,大多数突变,包括驱动突变,都是由组织特定的内源性过程引起的。我们确定了暴露于钴和乙烯基氯产生的特征,并将不同的人类特征(SBS19和SBS42)与1,2,3-三氯丙烷(TCP)(一种卤代烷烃和饮用水污染物)联系起来,并在人类肿瘤基因组中发现了这些特征和其他特征。我们定义肿瘤的跨物种基因组景观由一个重要的纲要与人类健康相关的代理人诱导。
Epidemiological studies have identified many environmental agents that appear to significantly increase cancer risk in human populations. By analysis of tumour genomes from mice chronically exposed to one of 20 known or suspected human carcinogens, we reveal that most agents do not generate distinct mutational signatures or increase mutation burden, with most mutations, including driver mutations, resulting from tissue specific endogenous processes. We identify signatures resulting from exposure to cobalt and vinylidene chloride and link distinct human signatures (SBS19 and SBS42) with 1,2,3-Trichloropropane (TCP), a haloalkane and pollutant of drinking water, and find these and other signatures in human tumour genomes. We define the cross-species genomic landscape of tumours induced by an important compendium of agents with relevance to human health.
