Abstract

The effect of simvastatin (MK-733), a potent 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, on the migration of cultured porcine smooth muscle cells (SMCs) was investigated in modified Boyden chambers. Platelet-derived growth factor (PDGF) stimulated the SMC migration dose dependently. MK-733 inhibited the migration response induced by PDGF with an IC50 value of 2 μM. Supplementation with mevalonate restored the migration response inhibited by MK-733 but the addition of low-density-lipoprotein (LDL) did not change the response. Another HMG-CoA reductase inhibitor, pravastatin (CS-514), also reduced the migration response. However its potency was far less than that of MK-733. MK-733 also inhibited the SMC migration stimulated by fibrinogen. These results suggest that non-sterol metabolite(s) of mevalonate, possibly prenylated proteins, are involved in a migration signaling pathway and that HMG-CoA reductase inhibitors are effective in the prevention of the formation of intimal hyperplasia in atherosclerosis.

    They have been found to regulate inflammatory transcription factors in human endothelial and vascular SMCs and inhibit leukocyte adhesion through reducing the expression of endothelial cell adhesion molecule [15,16]. Simvastatin has been demonstrated to suppress SMC proliferation [17] and migration [18], inhibit myointimal hyperplasia following carotid artery injury [19], and prevent hypercholesterolemia and atherosclerosis in cholesterol-fed rabbits [20]. Vytorin, a combination of simvastatin and ezetimibe, is a highly efficacious, well-tolerated treatment option for hypercholesterolemic patients [21].

    Furthermore, simvastatin has been shown to inhibit VSMC proliferation and uptake of aggregated cholesterol in human VSMCs [18, 19]. Evidence also exists that implicates statins in inhibition of VSMC migration [20–22]. In addition, migration and production of metalloproteinase-9 by monocytes is inhibited by statins [23].

    HA1004 is an H7 structural analog with a 20-fold lower inhibitory potency toward PKC but with similar effects on other kinases (34). Compounds H7 and HA1004 have been used together previously to define the role of PKC in cellular processes (35, 36). All of the compounds were not overtly cell toxic because they did not increase lactate dehydrogenase release at the concentrations used in these experiments (data not shown).
