Effects of aspirin on proliferation and apoptosis of mouse glioma stem cells in vitro
摘要
Abstract
Objective
2
To study the effects of aspirin on proliferation and apoptosis of mouse glioma stem cells (GSCs).
Methods
2
In vitro
cultured GSCs isolated from mouse glioma cell line GL261 were treated with 2.5
5.0 and 10 mmol/L aspirin
with normal saline as the control.The pro
liferation of GSCs was assayed using CCK-8 kit
and the changes in cell cycle distribution and cell apoptosis were detected with flow cytometry and TUNEL assay
respectively; LDH kit was used to assess the cell damage after aspirin treatment.
Results
2
Compared with the control cells
the GSCs treated with different concentrations of aspirin showed dose- and time-dependent inhibition of cell proliferation (
P
<
0.05) and obviously reduced number and size of the tumor spheres (
P
<
0.05).Aspirin caused obvious cell cycle changes in GSCs
shown by a significantly decreased percentage of S phase cells and an increased percentage of G
0
/G
1
phase cells (
P
<
0.05).Aspirin also induced obvious apoptosis of GSCs and significantly increased the release of cytosolic LDH (
P
<
0.05).
Conclusion
2
Aspirin inhibits the proliferation and promotes apoptosis of mouse GSCs
in vitro
.
