U-373-MG 세포의 이동 및 침윤에 미치는 Simvastatin의 효과

Simvastatins are widely used to reduce endogenous cholesterol synthesis and improve hypercholesterolemia. Also, simvastatin have been shown to induce both angiogenic and angiostatic responses. In this study, It was attempted to resolve this controversy by studying the effects of simvastatin on the cell migration and invasion with the proteinases secretion and expression pattern. U-373-MG cells treated with low dose of simvastatin (0.001~0.5 μM) showed the induction of migration and invasion compared with the addition of a control buffer. On the contrary, high dose of simvastatin (1~20 μM) showed the reduction of migration and invasion compared with the addition of a control buffer. It was also showed that simvastatin-regulated migrative and invasive phenotypes were consistent with the secretion and expression pattern of matrix metalloproteinase-2 (MMP-2), MMP-9 and plasmin.
