Human exposure to environmental toxins is a public health issue. The microarray data available in the Gene Expression Omnibus database under accession number GSE55655 and GSE55670GSE55655GSE55670 show the isolated and combined effects of dietary sugar and two organic compounds present in a variety of plastics [bisphenol A (BPA) and Bis(2-ethylhexyl) phthalate (DEHP)] on global gene expression in Drosophila melanogaster. The study was carried out with samples collected from flies exposed to these compounds for a limited period of time (48 h) in the adult stage, or throughout the entire development of the insect. The arrays were normalized using the limma/Bioconductor package. Differential expression was inferred using linear models in limma and BAGEL. The data show that each compound had its unique consequences to gene expression, and that the individual effect of each organic compound is maximized with the joint ingestion of dietary sugar.
人类接触环境毒素是一个公共卫生问题。基因表达综合数据库(Gene Expression Omnibus)中登录号为GSE55655和GSE55670(GSE55655、GSE55670)的微阵列数据显示了膳食糖以及多种塑料中存在的两种有机化合物[双酚A(BPA)和邻苯二甲酸二(2-乙基己基)酯(DEHP)]对黑腹果蝇整体基因表达的单独和联合影响。该研究使用了从成年阶段接触这些化合物有限时间(48小时)的果蝇,或在昆虫整个发育过程中接触这些化合物的果蝇所采集的样本进行。使用limma/Bioconductor软件包对阵列进行标准化。使用limma和BAGEL中的线性模型推断差异表达。数据表明,每种化合物对基因表达都有其独特的影响,并且每种有机化合物的个体效应在与膳食糖共同摄入时最大化。
