ABSTRACT
To study the in vitro anti-angiogenesis effect of three curcumin pigments (curcumin, demethoxycurcumin, bisdemethoxycurcumin). In the study, the inhibitory effect of the three curcumin pigments on proliferation of HUVEC cells induced by OX-LDL and the effect on migration of HUVEC cells were detected. The effect on neovascularization was observed by chorioallantoic membrane (CAM) test. The effect on cell adhesion factors ICAM-1 and VCAM-1 of HUVECs were tested by Real-time RT-PCR. It was found that the three curcumins could inhibit the proliferation of HUVEC cells induced by OX-LDL within the dosage range 4, 8, 16 mg x L(-1), with a dose-dependence. The proliferative effect of curcumins on HUVECs was greater than the other two derivatives (P < 0.01). All of the three curcumin pigments inhibited the migration of HUVEC cells and the angiogenesis of chick chorioallantoic membrane (CAM). The migration inhibition rate of curcumins at middle and high concentrations was greater than the other two (P < 0.01). All of the three curcumin could down-regulate the expression of VEGF and ICAM-1, and curcumins showed more obvious effect in down-regulating VEGF than demethoxycurcumin and bisdemethoxycurcumin(P < 0.01); Bisdemethoxycurcumin showed the most significant effect in down-regulating ICAM-1 (P < 0.01). All of the three showed no remarkable effect on expression of VCAM-1, and only bisdemethoxycurcumin showed the down-regulating effect (P < 0.05). According to the findings, all of the three curcumin pigments could resist angiogenesis by inhibiting proliferation and migration of endothelial cells and down-regulating the expression of VEGF and adhesion molecules ICAM-1.
