摘要：

目的研究肉桂醛对体外培养的人黑素瘤细胞株A375凋亡和血管内皮细胞生长因子(VEGF)及基质金属蛋白酶-9(MMP-9)表达的影响。方法 A375细胞在体外二维和三维培养后,在培养基中加入不同浓度(0,10,20和40μmol/L)肉桂醛,24小时后流式细胞仪检测细胞周期和凋亡,Western blot法检测VEGF蛋白水平,明胶酶谱法检测MMP-9分泌情况。结果肉桂醛能促进A375细胞凋亡,降低细胞增殖指数。40μmol/L肉桂醛作用后的A375细胞增殖指数最低(53.38±4.25%vs35.13±3.24%),细胞凋亡百分比最高(4.37±0.25%vs10.50±0.37%),各浓度间作用差异具有统计学意义(P<0.05)。肉桂醛作用后二维和三维培养的人黑素瘤细胞VEGF的表达下降(1.193±0.195vs0.204±0.017;1.549±0.214vs0.392±0.019),MMP-9的分泌也减少(24885.83±865.80vs14150.77±555.63;29408.50±817.62vs15121.43±497.95),各浓度肉桂醛间的抑制强度差异具有统计学意义(P<0.05)。结论肉桂醛能促进人黑素瘤细胞凋亡,抑制其增殖,并通过降低VEGF和MMP-9的表达来抑制人黑素瘤细胞的侵袭,其抑制强度与药物浓度成正比。
