摘要
目的:建立姬松茸多肽提取方法,并研究姬松茸多肽提取物对D-半乳糖(D-galactose,D-gal)致衰老模型小鼠的保护作用。方法:硫酸铵沉淀法从姬松茸蛋白酶解物分离多肽,用Sephadex G-50凝胶层析纯化得到姬松茸多肽;将ICR小鼠随机分为4组,即空白组、模型组、阳性药物(吡拉西坦)组和姬松茸多肽组,除空白组外,其余各组小鼠皮下注射300 mg/(kg mb·d)D-gal,建立衰老模型,通过Morris水迷宫和避暗仪测试小鼠学习记忆能力,检测小鼠血清总抗氧化能力(total antioxidant capacity,T-AOC)、丙二醛(malondialdehyde,MDA)浓度、过氧化氢酶(catalase,CAT)活力和活性氧(reactive oxygen species,ROS)水平;苏木精-伊红(hematoxylin-eosin,HE)染色观察小鼠脑组织海马区神经元结构变化;逆转录聚合酶链式反应(reverse transcription polymerase chain reaction,RT-PCR)检测脑组织中核因子E2相关因子2(nuclear factor erythroid 2-related factor 2,Nrf2)、NAD(P)H∶醌氧化还原酶(NAD(P)H:quinone oxidoreductase 1,NQO1)、谷氨酸半胱氨酸连接酶(glutamate-cysteine ligase,GCLM)m RNA相对表达量。结果:Sephadex G-50分离得一个明显色谱峰即为姬松茸多肽提取物;与模型组比较,姬松茸多肽组小鼠水迷宫及避暗潜伏期缩短,错误次数显著减少(P<0.05或P<0.01),血清CAT活力、T-AOC明显提高,ROS水平、MDA浓度显著下降(P<0.05或P<0.01);HE染色结果显示,与模型组相比,姬松茸多肽组小鼠神经元排列紧密,核固缩细胞数量减少;RT-PCR结果显示姬松茸多肽组小鼠脑组织中Nrf2、NQO1、GCLM mRNA相对表达量显著增高(P<0.05)。结论:姬松茸多肽提取物可以对D-gal致衰老模型小鼠产生保护作用,可能与其抗氧化作用相关。
