Gene regulation patterns of phytocompounds clustered by different kinetics of expression ratio (compared to LPS stimulation alone). The number of genes in each mode affected by cytopiloyne is shown above each left panel, while the percentage of these genes with an expression regulation mode similar to the other three test compounds is shown above. (A) The cluster of "early down-regulation followed by up-regulation". (B) The cluster of "early non-response followed by up-regulation". The Y-axis, in log2 scale, shows the ratio of gene expression level between "LPS with compound treatment" and "LPS stimulation alone".
