ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of fosinopril and metoprolol on metalloproteinases 9 (MMP9) expression of human umbilical vein endothelial cells (HUVECs) stimulated by oscillatory flow.</p><p><b>METHODS</b>HUVECs were exposed to steady laminar flow or oscillatory flow, laminar flow or oscillatory flow plus various concentrations (1 x 10(-7) mol/L, 1 x 10(-5) mol/L) of fosinopril and metoprolol for 4 and 24 hours. MMP9 mRNA and protein expressions of HUVECs were determined by RT-PCR and Western blot, respectively.</p><p><b>RESULTS</b>MMP9 expression at mRNA and protein levels were significantly increased in HUVECs exposed to oscillatory flow than that to laminar flow and these could be down-regulated by coincubation with fosinopril (1 x 10(-7) mol/L, 1 x 10(-5) mol/L, P < 0.01, P < 0.05, respectively) but not by co-incubation with metoprolol.</p><p><b>CONCLUSION</b>Fosinopril can attenuate the increased MMP9 expression at mRNA and protein levels of HUVECs exposed to oscillatory flow.</p>
