摘要 目的研究血管内皮生长因子(VEGF-β)的表达与人绒毛膜癌侵袭转移的关系,为临床基因治疗绒毛膜癌转移提供依据。方法应用逆转录PT-PCR检测JAR及JEG-3细胞中VEGF-βmRNA的表达,通过Matrigel体外实验对两种细胞的侵袭能力进行比较;构建小发夹RNA并转入JEC-3细胞,对VEGF-βmRNA前后的变化进行比较。结果 JEC-3和JAR中均检测到VEGF-βmRNA的表达,高侵袭性的JEC-3细胞中的VEGF-βmRNA的表达较JAR细胞明显增加(P<0.05);转染后JEG-3中的VEGF-βmRNA水平降低(P<0.05)。结论 VEGF-β参与绒毛膜癌的侵袭和转移,通过抑制VEGF-βmRNA的表达可以降低JEC-3的侵袭力。
