Protein kinase C beta/early growth response-1 pathway: a key player in ischemia, atherosclerosis, and restenosis

J Am Coll Cardiol. 2006 Nov 7;48(9 Suppl 1):A47-55. doi: 10.1016/j.jacc.2006.05.063. Epub 2006 Oct 17.

Abstract

Atherosclerosis, restenosis, and the consequences of ischemia are the major causes of morbidity and mortality worldwide. Elucidation of key contributing pathways in animal models of ischemia-reperfusion injury, atherosclerosis, and restenosis consequent to vascular injury may lead to great interest in determining if blocking these pathways could prevent vascular disease in human subjects. This review details the evidence that the protein kinase C (PKC) beta/early growth response-1 axis plays a central role in the response to both acute and chronic vascular stresses in animal models and also indicates the clinical implications of a specific inhibitor of PKCbeta, ruboxistaurin (LY333531).
