摘要 目的:观察选择性环氧合酶-2(COX-2)抑制剂Celebrex对裸鼠胰腺癌PC-3细胞株移植瘤生长和肿瘤组织VEGF和PGE2表达的影响.方法:观测Celebrex对移植瘤生长的影响,并采用放射免疫测定(RIA)和酶联免疫黏附测定(ELISA)检测裸鼠移植瘤组织中PGE2和VEGF的表达.结果:治疗组移植瘤生长曲线较对照组明显低平.对照组移植瘤近似体积为0.438 cm3,治疗组为0.212 cm3(抑瘤率为51.6%,P<0.05).PGE2表达,对照组为66±12 ng/g,治疗组为29±5 ng/g,两组间表达有非常显著性(P<0.01).VEGF表达,对照组1.11±0.11μg/g,治疗组0.66±0.11μ/g,VEGF抑制率为40.6%,两组间有显著性差异(P<0.05).结论:COX-2可能参与了肿瘤新生血管的生成,而PGE2可能在该过程中起着重要的介导作用,选择性COX-2抑制剂Celebrex则具有抑制肿瘤生长和对抗肿瘤新生血管生成的作用.
