Regulation of vascular smooth muscle cell growth by survivin.
The inhibitor of apoptosis protein survivin has long been of interest in the cancer literature for its role in both the regulation of cell proliferation and the inhibition of apoptosis. A growing body of literature has implicated survivin in the maladaptive pathways following vascular injury and, in particular, in the growth of vascular smooth muscle cells that comprise the hyperplastic neointimal lesions that characterize midterm vein bypass graft failure and restenosis following angioplasty and stenting. This review focuses on the emerging role of survivin in the regulation of smooth muscle cell growth and its implications for the prevention of restenosis following revascularization procedures. The expression, regulation, and function of survivin are addressed, as well as the current state of understanding regarding the effects of survivin inhibition in vitro and in vivo.
