Update on Abdominal Aortic Aneurysm Research: From Clinical to Genetic Studies

Figure 4

Heat map of the 57 differentially expressed genes found in two independent microarray studies for AAA. The heat map was produced by hierarchical clustering of the probeset data. Probesets for genes are represented by rows with the gene dendrogram at left. There are 61 probesets represented since there are redundant probesets on the Affymetrix microarray for some genes, for example, CXCR4, which is the gene represented by three lines at the bottom. Gene symbols and gene IDs on the right (found at http://www.ncbi.nlm.nih.gov/). Samples (4 AAA samples and 4 controls) are represented by columns. Green color indicates decreased expression in AAA and red color indicates increased expression in AAA.
