Biological functions identified by Ingenuity Pathway Analysis of significant differentially expressed genes (log2 ratio>±0.3) identified by SAM analysis (FDR = 13.5%).

*Significance calculated for each function is an indicator of the likelihood of that function being associated with the dataset by random chance. The range of p-values was calculated using the right-tailed Fisher's Exact Test, which compares the number of user-specified genes to the total number of occurrences of these genes in the respective functional/pathway annotations stored in the Ingenuity Pathways Knowledge Base.
