12/15-lipoxygenase (12/15-LO) has been implicated in the pathogenesis of vascular disease. Vascular smooth muscle cell (VSMC) proliferation is a key component of the response to injury in vascular disease. The role of 12/15-LO in regulating VSMC proliferation is poorly understood. Id3 has been shown to regulate growth in various cell types and is expressed in VSMCs within atherosclerotic and restenotic lesions. This study examines the role of Id3 in 12/15-LO-mediated VSMC proliferation.
