Abstract:
Background and purpose:Norcantharidin(NCTD)can inhibit the growth of tumors.In this study,we presented the chorioallantoci membrane(CAM)model to evaluate the effect of NTCD on angiogenesis and to study the anti-angiogenesis of NTCD in the chicken embro implant model of human breast carcinoma MCF-7 cells.Methods:The method was based on the implantation of gelatin sponges on top of growing CAM.The sponges were treated with various amounts of NCTD and 0.9% NaCl.Blood vessels surrounding CAM mesenchyme were counted.Then we established the MCF-7 chicken embryo implant model.The chicken embryo CAMs was treated with 0.9% NaCl,Various amounts of NCTD(72,36,18 ?g per 20 ?l)and the inhibition rates were calculated.Results:NCTD can inhibit the new capillary vessels growing into gelatin sponges placed on the CAM in a dose-dependent manner,and the inhibitory rates were 77.7%,62.9%,50.6% and 33.0% respectively.NCTD at the dosages of 72、36、18 ?g were able to inhibit capillary growth regardless of the angiogenic process induced by xenograft tumor and had a significant inhibition as compared with the control group,and the rates were 66.2%,39.3%,22.8% respectively.Conclusions:NCTD has an anti-angiogenic effect for targeting tumor angiogenesis.NCTD may be a potential therapeutic candidate for clinical application.
