摘要 目的探讨水溶性脂质体(WSLP)运载N-甲基-D-天冬氨酸受体1(NR1)小干扰RNA(siRNA)沉默大鼠脊髓NR1表达的可行性。方法根据文献合成WSLP,将合成的WSLP与siRNA连接形成WSLP/siRNA。将18只SD大鼠随机均分为3组:NS组(鞘内注射生理盐水)、WSLP/siRNA组(鞘内注射WSLP/siRNA混合物)、裸siRNA组(鞘内注射裸siRNA)。通过实时定量PCR和Western blot技术分别检测各组大鼠脊髓NR1 mRNA和蛋白表达水平的变化。结果 NS组与裸siRNA组脊髓NR1 mRNA和蛋白表达水平无明显差异,WSLP/siRNA组脊髓NR1mRNA和蛋白表达水平下降。结论 WSLP可有效运载siRNA沉默大鼠脊髓NR1 mRNA和蛋白表达,为WSLP运载NR1-siRNA治疗慢性疼痛的实验打下基础。
