Hierarchic clustering of BMP6 target genes. Differentially expressed genes were selected with a P value of .05 or less and ratio fold change of 1.5 or more, and were subjected to hierarchic cluster analysis. Median-centered clusters were viewed with Java-TreeView. Fold change relative to common reference is indicated by red (+1.5; full scale) and green (−1.5; full scale) intensity. (A) Global view of the clustered genes. (B) Detail of the clustered genes with selected genes labeled. Cluster 1 corresponds to genes in Table 1, and cluster 2 corresponds to genes in Table 2. The complete data set is accessible online through the University of North Carolina Microarray Database.²⁷
