Figure 3

Sample correlation matrix and hierarchical cluster analysis of gene expression profiles at different time points. A sample correlation matrix (upper panel) was built from groups evaluated at different time points. Red indicates high correlation and blue represents little correlation. In the original hierarchical unsupervised clustering (lower panel) the columns indicate the treatment condition with the designation 1 = 4 hours, 2 = 48 hours, 3 = 3 weeks and C = control. The rows indicate the individual genes, listed with their Genbank number. Increases and decreases in mRNA expression levels are represented by shades of red and blue.
