摘要
目的探讨Cav-1蛋白在帕金森病小鼠黑质表达情况及人参皂苷Rg1对其表达的影响及意义。方法将30只C57BL/6小鼠随机分为正常对照组(C组)、模型组(M组)、人参皂苷Rg1组(R组)。C组和M组小鼠腹腔注射生理盐水,R组小鼠腹腔注射人参皂苷Rg1预防给药,腹腔注射MPTP构建帕金森病模型。采用RT-PCR和Western blotting检测小鼠黑质Cav-1 mRNA和蛋白表达水平。结果M组小鼠黑质Cav-1 mRNA表达水平显著高于C组和R组(P<0.01)。M组小鼠黑质Cav-1蛋白表达水平显著高于C组和R组(P<0.01)。结论 Cav-1蛋白在帕金森病小鼠黑质区呈高表达,人参皂苷Rg1可能通过降低Cav-1蛋白的表达保护和修复多巴胺能神经元。
