摘要:

目的:探讨不同浓度β-淀粉样蛋白(Aβ1-42)激活的星形胶质细胞条件培养液(ACM)对PC12细胞存活率及脑源性神经营养因子(BDNF)、乙酰胆碱酯酶(AChE)蛋白表达的影响,以及β-细辛醚(β-asarone)的保护作用。方法:首先,将对数生长期的PC12细胞随机分为正常对照组、ACM(Aβ1-42 3.3 μmol/L)组、ACM(Aβ1-42 10 μmol/L)组、ACM(Aβ1-42 30 μmol/L)组,分别采用实时无标记动态细胞分析技术(Real Time Cell Analysis, RTCA)和MTT法检测各组PC12细胞的存活率,Western blot检测PC12细胞BDNF、AChE蛋白的表达;其次,将对数生长期的PC12细胞随机分为正常对照组、ACM(Aβ1-42 10 μmol/L)组、β-asarone(18.5、55.5、166.7 μg/mL)组,RTCA法检测PC12细胞存活率的改变,Western blot检测PC12细胞BDNF、AChE蛋白表达的变化。结果:ACM作用24 h,各组PC12细胞存活率无统计学差异(P>0.05),ACM作用36 h,ACM(Aβ1-42 10 μmol/L)组、ACM(Aβ1-42 30 μmol/L)组PC12细胞存活率显著降低(P<0.01);BDNF、AChE蛋白表达随Aβ1-42 浓度增加显著升高(P<0.05或P<0.01);β-asarone(18.5、55.5、166.7 μg/mL)能显著提高PC12细胞的存活率,β-asarone(55.5、166.7 μg/mL)组AChE表达相比于模型组显著下降(P<0.05或P<0.01),β-asarone(55.5 μg/mL)组与模型组比较BDNF表达增加(P<0.05)。结论:β-asarone能抑制AChE的上调,对BDNF的表达有促进作用,提示β-asarone对神经元细胞有一定的保护作用。

Abstract:

AIM: To investigate the effect of different concentrations of Aβ 1-42 activated-ACM cell on the viability and expression of BDNF, AChE of PC12 cells, and to explore the protective effects of β-asarone on the PC12 cells. METHODS: The logarithmic growth PC12 cells were randomly divided into normal group, ACM (Aβ1-42 3.3 μmol/L) group, ACM (Aβ1-42 10 μmol/L) group and ACM (Aβ1-42 30 μmol/L) group. The Real time cell analysis (RTCA) system and MTT assay were used to detect the survival rate of PC12 cells, respectively; Western blot assay was used to detect the expression of BDNF, AChE. The logarithmic growth PC12 cells divided into normal group, ACM (Aβ1-42 μmol/L) group, β-asarone(18.5 μg/mL, 55.5 μg/mL, 166.7 μg/mL) group randomly. The change of survival rate of PC12 cells was detected by RTCA assay; the expression of BDNF, AChE were detected by Western blot. RESULTS: There was no significant difference in the survival rate of PC12 cells in each group after ACM activated for 24 h (P>0.05); while the survival rate of PC12 cells was significantly reduced in ACM (Aβ1-42 10 μmol/L) group and ACM (Aβ1-42 30 μmol/L) group (P<0.01) after ACM activated for 36 h; the expression of BDNF, AChE protein increased significantly with the increase of the concentration of Aβ1-42 (P<0.05 or P<0.01); the survival rate of PC12 cells were significantly increased with β-asarone (18.5 μg/mL, 55.5 μg/mL, 166.7 μg/mL); the expression of AChE in β-asarone (55.5 μg/mL, 166.7 μg/mL) group was significantly lower than that in the model group (P<0.05 or P<0.01); the expression of BDNF in β-asarone (55.5 μg/mL) group was increased compared with that of the model group (P<0.05). CONCLUSION: β-asarone can inhibit the increase of AChE expression, and promote the expression of BDNF, suggesting that β-asarone has a certain protective effect on neurons.
