However, its mechanism of action is not fully understood. Our previous studies had shown that curcumin induced cytotoxicity, cell cycle arrest and apoptosis in human colon cancer colo 205 cells. In this study, curcumin affected the levels of NF-κB/ p65 in a time-dependent manner but did not affect NF-κB/ p50, based on Western blotting methods. In vitro experiments revealed that curcumin inhibited Cox-2 levels, but promoted those of Cox-1 in colo 205 cells. Curcumin also inhibited MMP-2 levels and promoted MMP-9 levels, but did not affect MMP-7 levels, based on Western blotting assays. These effects were also confirmed by cDNA microarray. Remarkably, curcumin not only exerted its effect on the protein levels of NF-κB, Cox-1 and -2, MMP-2 and -7, but also directly inhibited their mRNA levels. Curcumin was also found to significantly repress the in vitro invasion of colo 205 cells. Copyright© 2006 International Institute of Anticancer Research (Dr. John G. Delinassios), All rights reserved
