Dihydroartemisinin inhibits proliferation and invasion in human gastric cancer cells through suppression of Wnt/β-catenin signaling pathways
To investigate the effect of dihydroartemisinin (DHA) on the proliferation and invasion in gastric cancer cells and its possible molecular mechanism.
Methods
2
Human gastric cancer cell lines BGC-823 and SGC-7901 were exposed to different concentrations of DHA. MTT assay
wound healing assay
Transwell chamber test
and flow cytometry were used respectively to measure the cell proliferation
migration
invasion
and cell cycle distribution and apoptosis. The expression levels of DVL2
GSK-3β
p-GSK-3β
β-catenin and Cyclin D1 were detected by Western blotting.
Results
2
DHA inhibited the proliferation
invasion and migration of BGC-823 and SGC-7901 cells in a concentration-dependent manner (
P
<
0.05). DHA exposure for 48 h significantly increased the percentage of gastric cancer cells at S phase
and induced cell apoptosis (
P
<
0.05). DHA treatment resulted in the decreases in the protein levels of DVL2
p-GSK-3β
β-catenin and Cyclin D1 (
P
<
0.05)
and increase in that of GSK-3β (
P
<
0.05). SKL2001
agonist of the Wnt/β-catenin pathway
reversed the inhibitory effect of DHA on proliferation and invasion of gastric cancer cells (
P
<
0.05)
while the inhibitor
XAV939
enhanced the above effects of DHA (
P
<
0.05).
Conclusion
2
DHA inhibits the proliferation
invasion and migration
arrests the cell cycle at S phase and induces cell apoptosis in gastric cancer cells
which may be associated with its suppression of Wnt/β-catenin signaling pathway.
