Relationship among differentially regulated genes. A) Relationship between genes up-regulated by IL-1 and those down-regulated by TGF-β. Note that the overlapping region forms the Cluster 1C. B) Relationship between genes down-regulated by IL-1 and those up-regulated by TGF-β. Cluster names correspond to that described in Table III. Note that the overlapping region forms the Cluster 2C. See text for further explanation.

3. Fig. 2
A tree view representation of the Cluster 1. A hierarchical cluster analysis was performed as described in Materials and methods. Each row represents a gene and each column represents a sample. The colors represent relative intensity of the signal for each gene in each sample compared to the average intensity of the entire row; green: decrease, red: increase, black: no change. Cluster 1 consisted of genes up-regulated by IL-1. Two distinct sub-clusters were named Cluster 1A and 1B, respectively. A. A magnified view of the sub-cluster 1A. The sub-cluster 1AA contained majority of genes counter-regulated by TGF-β. B. The magnified view of the Cluster 1B. This sub-cluster contained all genes that are enhanced by TGF-β.
