摘要

目的

探讨川芎嗪(tetramethylpyrazine，TMP)对过氧化氢(H

)所致大鼠星形胶质细胞凋亡的保护作用。

方法

利用SD新生鼠(24~48 h)分离、培养星形胶质细胞，按随机数字表法分为空白对照组(以正常培养液培养)、模型组(100 μmol/L的H

作用24 h)、TMP剂量组(25、50、100 μmol/L TMP预处理48 h后，加入H

作用24 h)。采用CCK-8检测各组细胞存活率；GFAP染色观察细胞形态；流式细胞术检测各组细胞凋亡率；特定试剂盒检测乳酸脱氢酶(LDH)、超氧化物歧化酶(SOD)活力；Real-time PCR检测各组细胞中PI3K、AKT、Bcl-2、Bax、Caspase-3 mRNA的表达；Western blot检测各组细胞PI3K、AKT、p-AKT、Bcl-2、Bax、Caspase-3的蛋白表达。

结果

与空白对照组比较，模型组细胞存活率明显降低(

0.05)，细胞凋亡率升高(

0.05)，LDH含量增加(

0.05)，SOD活性降低(

0.05)，PI3K、AKT、Bcl-2 mRNA表达下调，Bax、Caspase-3 mRNA表达上调(

0.05)，PI3K、p-AKT、Bcl-2蛋白表达明显降低，Bax、Caspase-3蛋白表达明显升高(

0.05)；与模型组比较，TMP预处理后细胞存活率明显升高(

0.05)，其中50 μmol/L组的细胞存活率最高(

0.05)，细胞凋亡率明显降低(

0.05)，LDH含量降低(

0.05)，SOD活性升高(

0.05)，PI3K、AKT、Bcl-2 mRNA表达上调，Bax、Caspase-3 mRNA表达下调(

0.05)，PI3K、p-AKT、Bcl-2蛋白表达明显升高，Bax、Caspase-3蛋白表达明显降低(

0.05)。

结论

TMP对H

所致的大鼠星形胶质细胞氧化应激损伤具有保护作用，可改善损伤后细胞形态并抑制凋亡，该作用可能与PI3K、p-AKT蛋白活化有关。

Abstract

Objective

To investigate the protective effect of tetramethylprazine (TMP) on oxidative stress injur

y induced by hydrogen peroxide (H

) in rat astrocytes.

Methods

Astrocytes were isolated from SD newborn rats (24~48 h old) and cultured

and then the cells were randomly divided into control group (cultured with normal culture medium)

model group (100 μmol·L

-1

for 24 h)

TMP groups (pretreatment of 25

100 μmol·L

-1

TMP for 48 h

and then H

was added for 24 h). CCK-8 assay was used to detect cell survival rate

GFAP staining to observe cell morphology

flow cytometry to detect cell apoptosis

corresponding reagent test kits to detect the lactate dehydrogenase (LDH) content and superoxide dismutase (SOD) activity

real-time fluorescent quantitative PCR to measure the detect the mRNA expression of PI3K

AKT

Bcl-2

Bax and Caspase-3

and Western blotting to test the protein expression levels of PI3K

AKT

p-AKT

Bcl-2

Bax and Caspase-3 in each group of cells.

Results

The model group had significantly reduced cell survival rate (

0.05)

increased apoptotic rate (

0.05)

elevated LDH content (

0.05)

decreased SOD activity (

0.05); down-regulated PI3K

AKT

Bcl-2 mRNA and protein levels

and up-regulated the expression levels of Bax and Caspase-3 mRNA and protein levels (

0.05). Compared with the model group

TMP pretreatment resulted in significantly increased cell survival rate (

0.05)

lowest apoptotic rate (

0.05) and LDH content (

0.05)

enhanced SOD activity (

0.05)

up-regulation of PI3K

AKT

and Bcl-2 at mRNA and protein levels

and down-regulation of Bax and Caspase-3 at mRNA and protein levels (

0.05).

Conclusion

TMP exerts protective effects on oxidative stress injury of rat astrocytes i

nduced by H

and improves cell morphology and inhibits cell apoptosis after injury

and this effect may be related to the regulation of PI3K and p-AKT activation.
