ABSTRACT: The objective of this project was to search for consensus in differential gene expression data and in regulation of differentially expressed genes among DNA microarray studies of atherosclerotic vessels and plaque. Seventeen DNA microarray studies of atherosclerosis were analyzed. Only 19 genes were found to be differentially expressed in 3 or more of the studies. The nineteen genes belong to classic gene ontologies known to be involved in atherosclerosis: immunity and defense, metabolism, proteases, receptors, and signal transduction. Four bioinformatics programs (TRED, rVISTA, JASPAR, and Ariadne Pathways) were used to further analyze the promoter regions and common upstream regulators of the 19 genes. Twelve of the genes shared nine common upstream regulators, many of them known to affect atherosclerosis, and one possible new pathway was identified that may be involved in this disease.
