键合紫杉醇纳米胶束对H22肝癌小鼠的体内疗效评估

摘要

The anti-tumor effects of the polymer-paclitaxel conjugate micelles and free paclitaxel on H22 liver cancer bearing mice were evaluated. After 10 days drug administration, the tumor volume inhibition rates (VIR) of free paclitaxel group, polymer-paclitaxel conjugate micelles group at doses of 3 mg/kg, and the micelles group at doses of 6 mg/kg are 22% , 49% , and 67% , respectively. In addition, the tumor weight inhibition rates ( WIR) are 29%, 45%, and 47%, respectively. Protein expression results show that paclitaxel micelles group has higher expression of p53 and lower expression of bcl-2. All these results indicate that the anti-tumor effect of polymer-paclitaxel conjugate micelles is stronger than free paclitaxel.%以H22肝癌的balb/c荷瘤小鼠为动物模型,考察了紫杉醇纳米胶束、紫杉醇注射液和生理盐水对小鼠肿瘤的抑制效果.紫杉醇注射液组、紫杉醇纳米胶束低剂量组和紫杉醇纳米胶束高剂量组在给药后10 d的肿瘤相对体积抑制率分别为22％、49％和67％,瘤重抑制率分别为29％、45％和47％；蛋白表达检测结果显示,紫杉醇纳米胶束组呈现p53的高表达和bcl-2的低表达,说明紫杉醇纳米胶束对小鼠H22肝癌的抑制作用强于紫杉醇注射液.
