Fig. 3From: Transcriptional profiling of human bronchial epithelial cell BEAS-2B exposed to diesel and biomass ultrafine particlesExpression profiles of genes showing statistically significant expression changes over time in BEAS-2B cells exposed to diesel UFP. Genes have been grouped into 9 clusters showing distinct expression profiles during the time of the experiment. For each plot, the expression values of the clustered genes are represented in either control cell lines (green) or cells after UPF diesel exposure (red), respectively. Solid line indicates the median instead shadow the median ± S.D. (standard deviation) of the expression values at each time pointBack to article page
