title: Microarray-based analysis of anti-angiogenic activity of demethoxycurcumin on human umbilical vein endothelial cells: crucial involvement of the down-regulation of matrix metalloproteinase.
abstract: cDNA microarray-based gene expression analysis has been successfully employed to explore the action mechanism and to validate the targets of several drugs. In the present study, we evaluated anti-angiogenic activity of demethoxycurcumin (DC), a structural analog of curcumin, isolated from Curcuma aromatica, and investigated the effect of DC on genetic reprogramming in cultured human umbilical vein endothelial cells (HUVECs) using cDNA microarray analysis. Of 1024 human cancer-focused genes arrayed, 187 genes were up-regulated and 72 genes were down-regulated at least 2-fold by DC. Interestingly, 9 angiogenesis-related genes were down-regulated over 5-fold in response to DC, suggesting that the genetic reprogramming was crucially involved in anti-angiogenesis by the compound. To verify the results obtained from cDNA microarray analysis, matrix metalloproteinase-9 (MMP-9), the product of one of the angiogenesis-related genes down-regulated over 5-fold by DC, was investigated using gelatin zymography. DC potently inhibited the expression of MMP-9, yet showed no direct effect on its activity. These data show that gene expressional change of MMP-9 is a major mediator for angiogenesis inhibition by DC. All genes identified and microarray data are available on the web at http://dasan.sejong.ac.kr/~bioprobe/.
