Figure 3. Coexpression of genes.

Figure 3

The clustered matrix was obtained using the Pearson distance between expression profiles of genes across all comparisons of cell type, vessel type, and biological age. A PCC of 0 (black) indicates no interaction; a PCC of 1 (bright red) indicates 100% interaction; shading indicates level of interaction according to scale at top left. Diagonal white line indicates each gene compared to self. Relationships between groups of genes are represented by the dendrogram on the left of the figure. Its’ hierarchical clustering is based on the Euclidian distance matrix depicting the level of dissimilarity between the PCC of clusters of genes. The dendrogram illustrates the organization of these clusters with relation to other clusters within the gene list. Genes clustered more closely within the dendrogram (i.e., shorter brackets) have a higher degree of similarity in their coexpression profiles.
