目的:
2
研究川芎嗪(TMP)对叔丁基过氧化氢(t-BHP)诱导的PC12细胞损伤的保护作用及对磷脂酰肌醇3激酶(PI3K)/蛋白激酶B(Akt)/雷帕霉素靶蛋白(mTOR)信号通路的影响。
方法:
2
培养PC12细胞,孵育不同浓度的川芎嗪(10,25,50,100,200 μmol·L
-1
),12 h后采用细胞增殖毒性检测试剂盒(CCK-8)确定川芎嗪的保护浓度。随后将 PC12 细胞分为空白组,t-BHP 组,TMP组。空白组加入培养基,t-BHP组加入t-BHP(200 μmol·L
-1
),TMP组加入TMP(25,50,100 μmol·L
-1
)预处理 12 h 后加入t-BHP (200 μmol·L
-1
)。共作用6 h后采用酶联免疫吸附测定(ELISA)检测乳酸脱氢酶(LDH)漏出量、丙二醛(MDA)含量、超氧化物歧化酶(SOD)活性、活性氧(ROS)含量和谷胱甘肽过氧化物酶(GSH-Px)活性。采用蛋白免疫印迹法(Western blot)检测B淋巴细胞瘤-2(Bcl-2),Bcl-2相关X蛋白(Bax),Akt,磷酸化Akt(p-Akt)及mTOR,p-mTOR的表达情况。
结果:
2
与空白组比较,t-BHP组细胞生存率降低(
P
<
0.01),与t-BHP组比较,25,50,100 μmol·L
-1
的川芎嗪促进细胞增殖(
P
<
0.05,
P
<
0.01),其中50 μmol·L
-1
组的细胞增殖率最高(
P
<
0.01);与空白组比较,t-BHP组LDH的释放量,ROS和MDA含量显著增加(
P
<
0.01),SOD和GSH-Px的活性显著降低(
P
<
0.01),与t-BHP组比较,TMP组LDH的释放量,ROS和MDA含量显著降低(
P
<
0.05,
P
<
0.01),SOD和GSH-Px的活性显著升高(
P
<
0.05,
P
<
0.01);Western blot表明与空白组比较,t-BHP组中p-Akt,p-mTOR蛋白表达水平明显下降(
P
<
0.01),Bcl-2/Bax值明显降低(
P
<
0.01),与t-BHP组比较,TMP(50 μmol·L
-1
)组中p-Akt,p-mTOR蛋白表达水平明显上升(
P
<
0.05),Bcl-2/Bax值明显上升(
P
<
0.05)。另外LY294002(PI3K蛋白抑制剂)处理减弱了这些变化。
结论:
2
川芎嗪通过激活PI3K/Akt/mTOR信号通路保护t-BHP诱导的PC12细胞损伤。
Objective:
2
To study the protective effect of tetramethylpyrazine (TMP) on PC12 cells induced by tert-butyl hydroperoxide (t-BHP) and the regulatory mechanism on signaling pathway of phosphatidylinositol-3-kinases (PI3K)/kinase B (Akt)/mammalian target of rapamycin(mTOR).
Method:
2
PC12 cells cultured
in vitro
were treated with t-BHP (200 μmol·L
-1
) for 6 h to establish a model of oxidative damage in PC12 cells. The experiment was divided into blank group
model group (200 μmol·L
-1
t-BHP)
TMP group. PC12 cells were pretreated with TMP(25
50
100 μmol·L
-1
) for 12 h
and then treated with t-BHP for 6 h. The cell viability was detected by cell counting kit-8(CCK-8) method
and lactate dehydrogenase (LDH) leakage
malondialdehyde (MDA) content
superoxide dismutase (SOD) activity
reactive oxygen species (ROS) and glutathione peroxidase (GSH-Px) activity were detected by enzyme-linked immunosorbent assay (ELISA). Apoptosis was observed by annexin V-FITC/PI double staining. B-cell lymphoma-2 (Bcl-2)
Bcl-2-associated X protein (Bax)
total protein kinase B (Akt)
and phosphorylated protein kinase B (p-Akt)
mTOR and p-mTOR expressions were detected by Western blot.
Result:
2
The cell viability of PC12 cells treated with 200 μmol·L
-1
t-BHP decreased to about 50%after 6 h. This condition was suitable for the establishment of oxidative damage model. Compared with the model group
TMP (25
50
100 μmol·L
-1
) pretreatment for 12 h significantly increased the survival rate of PC12 cells (
P
<
0.05
P
<
0.01)
decreased the release of LDH and MDA (
P
<
0.05
P
<
0.01)
significantly reduced the ROS content in PC12 cells (
P
<
0.01)
significantly increased the activity of SOD
GSH-Px (
P
<
0.05
P
<
0.01)
and inhibited the cell apoptosis. Western blot showed that compared with the model group
the protein expressions of p-Akt and p-mTOR in TMP (50 μmol·L
-1
) pretreatment group increased significantly (
P
<
0.01)
and the Bcl-2/Bax ratio increased significantly. Treatment with LY294002 (PI3K protein inhibitor) also attenuated these changes.
Conclusion:
2
Ligustrazine protects PC12 cell injury induced by t-BHP by activating PI3K/Akt/mTOR signaling pathway.
