肿瘤细胞多药抗药性的形成机理除了与细胞膜P-糖蛋白过度表达、DNA拓外异构酶Ⅱ含量与活性改变有关外,同时还涉及细胞内谷胱甘肽、蛋白激酶C等变化。本文综述了近年来研究所取得的一些新进展。
In addition to the overexpression of P-glycoprotein and DNA exo-Ⅱ activity, the mechanism of multi-drug resistance of tumor cells is related to changes in intracellular glutathione, protein kinase C and so on. This article summarizes some recent advances made in recent years.
