  1. The pathways with the three lowest p-values from Fisher's exact test for pathways from IPA's "Canonical Pathways" database for each tissue are reported here along with the corresponding p-value from a right-tailed Fisher's exact test, the Benjamini-Hochberg (BH) adjusted p-value, and the genes within the pathway that showed differential expression within the respective tissue (Members). Arrows in the Members column indicate the direction of change in lactating animals relative to controls.
