摘要 目的:探讨Chk1/chk2在Aβ致伤海马神经元中的表达及意义。方法:应用新生(3d以内)SD大鼠采用急性分离、胰酶消化的方法培养海马神经细胞,分别于Aβ25-35致伤0h、8h、16h、24h,并采用免疫细胞染色观察各时间点Chk1/chk2表达情况。结果:体外培养的神经细胞生长状态良好,免疫细胞染色鉴定结果表明Chk1、chk2蛋白在Aβ致伤神经元后,随致伤时间延长均有表达,且以chk1表达显著,在致伤16h有差异明显(P<0.05)。结论:Chk1/chk2共同参与了在Aβ致伤海马神经元中的DNA损伤修复,以chk1表达更显著,提示可望为AD中神经元的DNA损伤修复提供新的干预点。
