Effect of sorafenib combined with thalidomide on angiogenesis in chick chorioallantoic membrane / 临床肝胆病杂志

ABSTRACT

ObjectiveTo investigate the effect of sorafenib and/or thalidomide on angiogenesis in chick chorioallantoic membrane (CAM). MethodsWhite eggs incubated for 7 days were used to establish a CAM model. The model eggs were randomly divided blank control group, sorafenib group, thalidomide group, and sorafenib/thalidomide group. After treatment, each egg was incubated for another 2 days. The CAM samples were collected and fixed to take their pictures under a microscope, and the vascular coverage of each sample was calculated. Comparison between these groups was made by analysis of variance, and comparison between each two groups was made by SNK-q test. ResultsThe thalidomide group or sorafenib group had significantly lower vascular coverage than the blank control group (30.2%±2.9% or 26.5%±2.1% vs 38.3%±2.7%, P＜0.05). The sorafenib/thalidomide group had significantly lower vascular coverage than the thalidomide group or sorafenib group (12.6%±1.5% vs 30.2%±2.9% or 26.5%±2.1%, P＜0.05). ConclusionBoth sorafenib and thalidomide have a good anti-angiogenic effect on CAM, but a combination of the two drugs shows better efficacy.
