Thrombomodulin (TM) is an essential cofactor for the physiologic activation of the anticoagulant protein C by thrombin. We have observed that the expression of TM mRNA in response to retinoic acid was markedly increased in human U937 monoblast-like cells, and human MEG01 megakaryocyte-like cells, but not in human umbilical vein cells, murine hemangioma cells, human K562 erythroblast-like cells, and murine HSD fibroblast-like cells. TM activity in U937 cells and MEG01 cells was not detectable in untreated cells, but developed rapidly after treatment with retinoic acid. In endothelial cells there was minimal change in TM activity in response to retinoic acid treatment. We have isolated clones for the genes for murine and human TM and have identified potential retinoic acid response elements in the 5'-flanking region of the human gene. In U937 cells the increase in mRNA levels was associated with increased transcription, and transient transfection studies with reporter plasmids demonstrate functional retinoic acid response elements present in the 5'-flanking region of the gene. Deletion of, and mutations introduced into, the potential retinoic acid response element confirm the functional response in transient transfections.
