MT01/PEN复合物对人成骨样细胞MG63表达骨保护蛋白和核因子κB受体活化因子配体的影响
目的应用聚乙烯亚胺阳离子聚合物(PEN)载体装载寡脱氧核苷酸MT01,制备MT01/PEN复合物,检测该复合物对人成骨样细胞MG63表达骨保护蛋白(OPG)和核因子κB受体活化因子配体(RANKL)的影响。方法制备3种不同配比的MT01/PEN(质量比分别为1:2、1:4、1:6)复合物,以全硫代化修饰MT01(MT01-s)和未修饰的MT01作阳性对照,分别转染MG63细胞。采用酶联免疫吸附测定法和real-time聚合酶链反应法分别检测培养24、48、72h时各组上清液及细胞内OPG和RANKL的表达水平。结果经MT01/PEN复合物转染后,上清液及细胞内OPG表达水平均升高(P〈0.05...

Summary: | 目的应用聚乙烯亚胺阳离子聚合物(PEN)载体装载寡脱氧核苷酸MT01,制备MT01/PEN复合物,检测该复合物对人成骨样细胞MG63表达骨保护蛋白(OPG)和核因子κB受体活化因子配体(RANKL)的影响。方法制备3种不同配比的MT01/PEN(质量比分别为1:2、1:4、1:6)复合物,以全硫代化修饰MT01(MT01-s)和未修饰的MT01作阳性对照,分别转染MG63细胞。采用酶联免疫吸附测定法和real-time聚合酶链反应法分别检测培养24、48、72h时各组上清液及细胞内OPG和RANKL的表达水平。结果经MT01/PEN复合物转染后,上清液及细胞内OPG表达水平均升高(P〈0.05);多数组中RANKL表达水平降低,而0PG/RANKL比值呈升高趋势(P〈0.05);不同质量配比的MT01/PEN均对MG63细胞的成骨具有影响,其中质量比为1:6时作用最明显。结论应用PEN作为基因载体装载MT01可增强MT01对MG63细胞的促成骨作用。 |

Methods MG63 cells were transfected by MT01/PEN complexes formed with three different mass ratios (1 : 2, 1 : 4, 1 : 6) of MT01 to PEN. MT01 and MT01-s were used as positive control. Enzyme-linked immunosorbent assay and real-time polyrnerase chain reaction were performed to |
