Polymorphisms in genes that encode for metabolic enzymes have been associated with variations in enzyme activity between individuals. Such variations could be associated with differences in individual exposure to carcinogens that are metabolized by these genes. In this study, we examine the association between polymorphisms in several metabolic genes and the consumption of tobacco in a large sample of healthy individuals. The database of the International Collaborative Study on Genetic Susceptibility to Environmental Carcinogens was used. All the individuals who were controls from the case-control studies included in the data set with information on smoking habits and on genetic polymorphisms were selected (n = 20938). Sufficient information was available on the following genes that are involved in the metabolism of tobacco smoke constituents: CYP1A1, GSTM1, GSTT1, NAT2 and GSTP1. None of the tested genes was clearly associated with smoking behavior. Information on smoking dose, available for a subset of subjects, showed no effect of metabolic gene polymorphisms on the amount of smoking. No association between polymorphisms in the genes studied and tobacco consumption was observed; therefore, no effect of these genes on smoking behavior should be expected.
编码代谢酶的基因多态性与个体间酶活性的差异有关。这种差异可能与个体接触由这些基因代谢的致癌物的差异有关。在本研究中,我们在一大群健康个体中检测了几个代谢基因的多态性与烟草消费之间的关联。使用了国际环境致癌物遗传易感性协作研究数据库。从数据集中纳入的病例对照研究中选取所有作为对照且有吸烟习惯和基因多态性信息的个体(n = 20938)。对于以下参与烟草烟雾成分代谢的基因有足够的信息:CYP1A1、GSTM1、GSTT1、NAT2和GSTP1。所检测的基因均未与吸烟行为有明显关联。部分受试者有吸烟剂量信息,结果显示代谢基因多态性对吸烟量没有影响。在所研究的基因多态性与烟草消费之间未观察到关联;因此,不应预期这些基因对吸烟行为有影响。
