Abstract
目的 探讨唑来膦酸诱导Bel-7402人肝癌细胞分化作用,为肝癌的分化治疗提供可借鉴的资料.方法选用反映肝细胞恶变的甲胎蛋白(AFP)的分泌量、γ-谷氨酰转肽酶(γ-GT)和醛缩酶(ALD),反映肝癌细胞分化的酶学指标酪氨酸-α-酮戊二酸转氨酶(TAT),鸟氨酸氨基甲酰转移酶(OCT)和碱性磷酸酶(ALP)作为观察肝癌细胞恶性表型逆转的指标.结果Bel-7402人肝癌细胞经0.05ug/ml唑来膦酸处理后,AFP分泌量明显低于对照组,γ-GT和ALD活力也明显低于对照组;相反,OCT、TAT和ALP的活力则明显高于对照组,差异均有显著意义(P＜0.05或P＜0.01).结论证明唑来膦酸是体外培养Bel-7402人肝癌细胞有效的分化诱导剂。
