摘要:目的:探讨可卡因-安非他命调节转录肽(CART)对糖氧剥夺(OGD)诱导的大鼠
皮层神经元内质网应激的作用。方法:18 天 SD 大鼠胚胎(E18)皮层神经元原代培养 8 天,
采用糖氧剥夺法(OGD)诱导神经元损伤。用 MTT 法检测细胞的存活率、western blotting
方法检测内质网应激反应标志分子(GRP78,caspase 12 和 CHOP)。结果:与对照组比较,
OGD 组的神经元存活率显著降低(P < ),内质网应激标志分子 GRP78、CHOP 和
caspase12 表达增多(P < )。CART 预处理组神经元的细胞活性明显高于 OGD 组(P <
),GRP78、CHOP 和 caspase12 表达明显低于 OGD 组(P < )。结论:CART 通
过抑制内质网应激反应减轻 OGD 诱导的大鼠皮层神经元损伤。

Abstract: Object: To investigate the effect of cocaine- and amphetamine-regulated transcript
(CART) on oxygen and glucose deprivation (OGD)-induced endoplasmic reticulum stress in rat
cortical neurons. Method: The primary cultured cortical neurons were established from embryonic
rats (E18). The neuronal injury was induced by OGD method. The cell survival was analysed by
MTT method, and the expression of endoplasmic reticulum stress (E
