摘 要: | 多药耐药(MDR)是导致胃癌化疗失败的主要原因.研究表明,胃癌MDR的发生机制与多个因素相关,主要有P-糖蛋白(P-gp)和多药耐药相关蛋白(MRP)过表达、谷胱甘肽转移酶-π(GST-π)活性增强、拓扑异构酶Ⅱ(TopoⅡ)含量减少、DNA损伤修复能力增强.

Multidrug resistance related mechanisms in gastric cancer |

Abstract: | Multidrug resistance (MDR) is the main cause of chemotherapy failure. MDR of gastric cancer is associated with a number of factors, including over-expression of P-glycoprotein (P-gp) and MDR associated protein (MRP), ghtathione S-transferase-π(GST-π) activity increasing, topoisomerase Ⅱ(Topo Ⅱ) decreasing and DNA damage-repair ability enhancement. |
