摘要 雷公藤内酯醇(triptolide,TPL)是从中国传统中药雷公藤中提取的有效成分.近年来的研究发现,TPL不仅具有抗炎、抗免疫反应等多种药理作用,还具有广谱抗肿瘤作用,是一种多靶点的天然抗肿瘤药物[1-4].实验表明,TPL能抑制体外培养的胰腺癌细胞增殖及胰腺癌动物移植瘤的生长[1].环氧化酶-2(cyclooxygenase-2,COX-2)为一种诱导型酶,与多种肿瘤的发生、发展密切相关[5].研究发现,TPL不仅可通过抑制COX-2表达调控炎症过程,还可通过下调COX-2表达抑制结肠癌细胞的增殖和迁移[2,6].然而TPL是否也通过下调胰腺癌细胞COX-2的表达而抑制肿瘤生长目前尚不清楚.本研究应用TPL干预人胰腺癌PANC1细胞,观察其对细胞增殖、凋亡、迁移和侵袭的作用,探讨其相关机制。
