[…] figure a)., next, we identified differentially expressed biological process go terms (degos) in each tissue by first ranking all genes in descending order of limma significance and then performing iterative group analysis (iga) [] for each go term with ≤ 100 constituent genes. we computed p-values for each term’s iga score using a null distribution obtained via 1000 random permutations […]

[…] were compared to the untreated ones. the rank product method [] was used to identify genes consistently up- or down-regulated. gene ontology (go) analysis was applied for functional studies using iterative group analysis (iga) [] utilizing the source database http://source.stanford.edu[]. false discovery rates for go-terms were estimated by performing 100 permutations., in the ex vivo […]
