To evaluate the interaction effects of Polycyclic aromatic hydrocarbons (PAHs) exposure and variants in genes on mitochondrial DNA copy number (mtDNAcn) in workers.
The mtDNAcn was determined by real-time quantitative polymerase-chain reaction in 544 PAHs-exposed workers and 238 office workers. The polymorphisms were detected by flight mass spectrometry.
The mtDNAcn in PAHs exposure group was significantly lower than non-occupational exposure population ( < 0.00). The cGAS rs610913 CA+AA had significant interaction effects with STING rs11554776 GG+GA ( = 0.035), rs7380824 CC+CT ( = 0.026), and rs78233829 GC+CC ( = 0.034) on mtDNAcn. The generalized linear model results showed that the influencing factors of mtDNAcn include PAHs exposure ( < 0.001) and the interaction of PAHs exposure and 311678 AA+AG ( = 0.047).
The influencing factors of mtDNAcn include PAHs exposure and the interaction of PAHs exposure and 311678 AA+AG.
评估多环芳烃（PAHs）暴露与基因变异对工人线粒体DNA拷贝数（mtDNAcn）的交互作用。
采用实时定量聚合酶链反应测定544名PAHs暴露工人和238名办公室工作人员的mtDNAcn。通过飞行质谱法检测基因多态性。
PAHs暴露组的mtDNAcn显著低于非职业暴露人群（<0.00）。cGAS rs610913 CA+AA与STING rs11554776 GG+GA（=0.035）、rs7380824 CC+CT（=0.026）和rs78233829 GC+CC（=0.034）对mtDNAcn有显著交互作用。广义线性模型结果显示，mtDNAcn的影响因素包括PAHs暴露（<0.001）以及PAHs暴露与311678 AA+AG的交互作用（=0.047）。
mtDNAcn的影响因素包括PAHs暴露以及PAHs暴露与311678 AA+AG的交互作用。
