Abstract： 目的研究Vasostatin转基因对胰腺癌细胞、血管内皮细胞的作用,探讨其对胰腺癌生长抑制的作用机制.方法应用腺病毒载体将Vasostatin基因转入人胰腺癌细胞SW1990、人脐静脉血管内皮细胞ECV304,应用MTT方法检测转基因后细胞的生长活力.同时,应用小管形成实验研究Vasostatin对血管内皮细胞ECV304体外血管生成的影响.结果 Vasostatin转基因对人胰腺癌SW1990细胞生长无显著影响.Vasostatin转基因(MOI分别为25和50)对人脐静脉血管内皮细胞ECV304作用72 h后,Ad-Vasostatin组的ECV304细胞数目显著少于PBS组和Ad-lacZ组(P < 0.05).小管形成实验结果显示,Ad-Vasostatin组内皮细胞数目较少,细胞排列连续性差,可见条索状的细胞链,但中空闭合的管状结构缺如.结论腺病毒介导的Vasostatin基因可显著抑制人脐静脉血管内皮细胞ECV304的体外细胞增殖,抑制其体外血管生成,而对人胰腺癌肿瘤细胞SW1990的体外细胞增殖无明显影响.
