在几个工作组中,职业暴露于空气污染会引起氧化应激,长期暴露会增加对心血管和呼吸系统疾病的易感性。这些受试者的生物流体可能反映了受干扰的代谢表型。在这项研究中,我们进行了比较分子谱研究,使用平行的生物流体收集的主题(n = 85)属于自动人力车司机(ARD),交通警察(TC)和办公室工作人员(OW)。与OW和TC相比,观察到ARD受试者血清中的氧化应激和炎症标志物水平更高。单因素和多因素分析的代谢产物确定在尿中的1H NMR显示11失调分子在ARD的主题,涉及苯丙氨酸,组氨酸,精氨酸和脯氨酸代谢。尽管混杂因素,如暴露时间,饮食因素,包括吸烟和饮酒状况的贡献,我们的研究结果表明,暴露特定的代谢型存在于ARD,OW和TC组的生物流体。通过NMR监测血清氧化应激和炎症标志物以及尿液代谢物可能有助于表征暴露于城市交通空气污染的人群中的扰动代谢表型。
Occupational exposure to air pollution induces oxidative stress and prolonged exposure increases susceptibility to cardiovascular and respiratory diseases in several working groups. Biofluid of these subjects may reflect perturbed metabolic phenotypes. In this study we carried out a comparative molecular profiling study using parallel biofluids collected from subjects (n = 85) belonging to auto rickshaw drivers (ARD), traffic cops (TC) and office workers (OW). Higher levels of oxidative stress and inflammation markers in serum of ARD subjects were observed as compared to OW and TC. Uni and multivariate analyses of metabolites identified in urine by 1H NMR revealed 11 deregulated molecules in ARD subjects and involved in phenylalanine, histidine, arginine and proline metabolism. Despite contribution of confounding factors like exposure period, dietary factors including smoking and alcohol status, our results demonstrate existence of exposure specific metabotypes in biofluids of ARD, OW and TC groups. Monitoring serum oxidative stress and inflammation markers and urine metabolites by NMR may be useful to characterize perturbed metabolic phenotypes in populations exposed to urban traffic air pollution.
