Representative canonical pathways study using the ingenuity pathway analysis (IPA) tool.

<p>(A) A comparison of the numbers of pathways that are statistically significant is shown for each point (t7 vs t21 and t0 vs t21). (B) The numbers of genes that are differentially expressed in each of the pathways are depicted for t7 vs t21 and (C) t0 vs t21. Down-regulation is shown in green and up-regulation in red.
