The pathways and genes included in each pathway were based on the output of Ingenuity Pathway Analysis (IPA; http://www.ingenuity.com/). Some pathways may be partially overlapped with others. No action was taken to remove any possible redundancy
The FDR values were computed based on the p values of the pathways included in the IPA output via the method of Benjamini and Hochberg (1995). Pathways with FDR <0.05 are included in Table 2
