Figure 6. Temporal differences in activation of IL6 signaling after APAP300 and PHX.
Ingenuity Pathway Analysis (IPA) of microarray data showing (A) predicted inhibition of IL6 signaling at 3 hr and (B) activation at 24 hr after APAP 300 compared to PHX, based on downstream gene expression profile. As shown in Figure 2, IL6 was activated as early as 3 hr after PHX, while activation was delayed (starting from 12 hr) after APAP300. Positive or negative z-score (absolute z-score > 2 considered as significant) represents predicted activation or inhibition of upstream regulator based on expression profile of downstream genes. p-values signifies extent of overlap between set of downstream target genes of a upstream regulator in dataset compared to all known downstream target genes of that upstream regulator in the reference genome. (red shapes: upregulated genes; green shapes: downregulated genes with intensity of color reflecting extent of upregulation or downregulation; blue center shape: predicted inhibition; orange center shape: predicted activation)
