Survivin expression is up-regulated in vascular injury and identifies a distinct cellular phenotype

The regulation of cell proliferation, death, and phenotype after vascular interventions remains incompletely understood. We investigated the role of the inhibitor of apoptosis protein survivin in diverse models of vascular injury. The results suggest that survivin is an important modulator of the generalized vascular injury response and may represent a relevant target for therapies targeting intimal hyperplasia.
