| 摘 要： | 目的：研究shRAKC1对慢性成瘾小鼠脑组织CREB mRNA、蛋白的表达变化。方法：通过条件性位置偏爱（CPP）实验分析shRAKC1对慢性吗啡成瘾小鼠的作用；通过RT-PCR检测RACK1和CREB的mRNA在成瘾小鼠海马中的表达水平，并采用免疫组化观察RACK1和CREB蛋白的表达情况。结果：慢性成瘾组与生盐水组相比，前者海马区RACK1和CREBmRNA表达升高（p〈0．05），且吗啡诱导的CPP效应增强（p〈0．05），而shRAKC1组与空质粒组相比，前者由吗啡诱导的CPP诱导效应减弱（p〈0．05），同时其海马区RACK1和CREBmRNA表达下降（p〈0．05）。结论：干扰慢性吗啡成瘾小鼠RACK1表达，可以使CREB表达水平下调，并有抑锏吗啡成瘾效应的作用。

| Abstract: | Objective： To investigate the effects of shRACK1 on CREB in hippocampus of mice. Method： Analysing the effects of CPP in hippocampus of mice. The expression of RACKI and CREB were determined by RT-PCR and Immunohistochemistry. Result： The level of RACK1 and CREB mRNA in morphine-induced group is higher than in the saline group（p〈0. 05）, morphine-indueed group＇s CPP is increased（p〈0. 05）. And the level of RACK 1 and CREB mRNA in control plasmid group is higher than in shRACK1 group（p〈0. 05）, morphine-induced group＇s CPP is decreased（p〈0. 05）. Conclusion： shRACK1 in mice with chronic morphine dependence can decrease the expression of CREB, and it can decrease the effects of chronic morphine dependence. |
