Abstract
A growing number of recent studies have focused on anticarinogenic, antimutagenic or chemopreventive activities of phytochemicals, particularly those included in human diet. Curcumin, a dietary pigment in turmeric, gas been shown to have a wide range of biological activities including anti-inflammatory, anticarcinogenic and antimetastatic effects. In the present study, we attempted to study the possible anti-invasive have previously been shown to be highly invasive. Here, we show that curcumin inhibits H-ras- transformed MCF 10 A human breast epitheliual cells which have previously been shown to be highly invasive. Here, we show that curcumin inhobots H-ras-induced invasive phenotype in MCF10A cells. A significant downregulation of matrix meralloproteinase (MMP)-2 by curcumin is observed while the activity of MMP-9 is not changed, suggesting that MMP-2 is more likely involved in the inhibitory effect of curcumin than MMP-9. We also show that curcumin treatment inhibits cell growth dose- dependently and induces internucleosomal DNA fragmentation in H-ras MCF10A cells and MCF7 human breast carcinoma cells. These results demonstrate that curcumin induces apoptosis in transformed human breast epithelial cells and breast carcinoma cells, suggesting a potential use of curcumin as a chemopreventive agent for breast cancer.
