摘要

目的探讨血管内皮生长因子受体2(kinase insert domain-containing receptor,KDR)反义寡核苷酸(antisense oligode-oxynucleotides,ASODN)对人前列腺癌PC-3细胞的增殖调控作用。方法设计并合成KDR的正义、反义寡核苷酸,经脂质体介导转染人前列腺癌PC-3细胞。用噻唑盐法观察不同浓度(0.01,0.05,0.1,0.2,0.4μmol/L)正义、反义寡核苷酸及阳离子脂质体对肿瘤细胞增殖的抑制作用,RT-PCR方法检测不同浓度(0.01,0.05,0.1,0.2,0.4μmol/L)ASODN转染后KDRmRNA的表达情况...
