In this study, we examined the molecular mechanism by which agents that elevate intracellular cAMP inhibit the expression of the tumor necrosis factor alpha ( TNFalpha ), tissue factor , endothelial leukocyte adhesion molecule-1 , and vascular cell adhesion molecule-1 genes .
 ( protein: endothelial leukocyte adhesion molecule-1, None) , ( protein: tissue factor, None) , ( protein: TNFalpha, None) , ( protein: vascular cell adhesion molecule-1, None) , ( DNA: vascular cell adhesion molecule-1 genes, None) , ( protein: tumor necrosis factor alpha, None)
