Effect of Wendantang-containing Serum on Apoptosis and Expressions of PI3K,Akt and GSK3β in Astrocytes Under Glutamate Environment
To investigate the protective effect of Wendantang-containing serum on astrocytes in glutamate environment and its effect on phosphatidylinositol 3 kinase (PI3K)/protein kinase B (Akt)/glycogen synthetase kinase 3
β
(GSK3
β
) signal pathway.
Method
2
Totally 60 rats were randomly divided into 5 groups
normal group (
n
=20)
clozapine group
and high
medium and low-dose Wendantang groups
with 10 rats in each group. Normal group was given 20 mL·kg
-1
normal saline
clozapine group was given 20 mg·kg
-1
clozapine
Wendantang groups were given 40
20
10 g·kg
-1
Wendantang
once a day. Eight days later
the rats were killed
their blood was taken
serum was centrifuged
inactivated
filtrated
sterilized and filled in separate centrifugal tubes. The astrocytes were divided into normal group
model group
clozapine group
and high
medium and low-dose Wendantang groups. The normal group and the model group were cultured with normal serum
and the rest groups were cultured with corresponding drug containing serum. The other groups were treated with 10 mmol·L
-1
glutamic acid for 24 hours
and then the apoptosis of astrocytes was detected by flow cytometry. Western blot and Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) were used to determine protein
and mRNA expressions of PI3K
Akt
GSK3
β
in astrocytes.
Result
2
Compared with the normal group
apoptosis in model group increased significantly (
P
<
0.01). Compared with the model group
apoptosis in Wendantang groups decreased significantly (
P
<
0.01). Compared with the normal group
protein and phosphorylation expressions of PI3K
Akt
GSK3
β
in model groups decreased significantly (
P
<
0.05
P
<
0.01). Compared with the model group
protein and phosphorylation expressions of PI3K
Akt
GSK3
β
in Wendantang groups increased (
P
<
0.05
P
<
0.01). Compared with the normal group
expressions of PI3K
Akt and GSK3
β
mRNA decreased in model group(
P
<
0.01). Compared with the model group
expressions of PI3K
Akt and GSK3
β
mRNA increased significantly in Wendantang groups group (
P
<
0.05,
P
<
0.01).
Conclusion
2
Wendantang-containing serum can effectively increase expressions of PI3K
