Hierarchical clustering of GO terms. (a) The first ring next to the dendrogram represents the log₂FC of the genes, which were actually the leaves of the clustering tree. Genes were grouped by their log₂FC value. (b) Genes were clustered based on different terms. Most genes involved in extra cellular space were up-regulated while most genes in cellular response to tumor necrosis factor term were down-regulated.
