A retinoic acid-induced signature in CD34+ cells from CAD patients. A. The induced signature in CD34+ cells from CAD patients correlates with the expression of RAI1. The average expression of the 303 genes of the induced signature of CAD patients is plotted against the expression of RAI1 (CAD patients are represented by squares, controls by triangles). B. Retinoic acid-induced 1 gene expression in different cell types in CAD patients and controls. C. The expression of RAI1 is shown for all studied cell types in CAD patients (squares) and controls (triangles).
