利用代谢组学研究大气细颗粒物的生殖毒性效应
Study on Reproductive Toxicity of Fine Particulate Matter by Metabolomics
摘要
Abstract
Air born fine particulate matter (PM2.5) pollution is a serious environmental problem, and it is very important to study the toxicity effect and mechanism of PM2.5.In this study, a liquid chromatography-mass spectrometric (LC-MS) method on the basis of metabolomics technique was developed to investigate the metabolic disruption effect and reproductive toxicity mechanism of PM2.5 on rat testis.The profile of aqueous and organic testis metabolic extracts were acquired, and then analyzed by partial least square-discriminant analysis and nonparametric test.The results showed that control group and treatment group were clearly discriminated in the scoring plot of PLS-DA models, indicating PM2.5 treatment induced significant difference in testis metabolome.A total of 56 differential metabolites were identified, and further pathway analysis suggested that PM2.5 exposure induced amino acid and nucleotide metabolism disorder, steroid hormone metabolism imbalance and abnormal lipid metabolism.These important pathways may be the key molecular events in the PM2.5 reproductive toxicity.关键词
