Effects of polyphyllin Ⅵ on the proliferation and apoptosis of glioma cells and potential mechanism
To investigate the effects of polyphyllin Ⅵ(PPⅥ) on the proliferation and apoptosis of glioma cells and potential mechanism.
METHODS
2
Using human glioma LN229 cells as objects, MTT assay was used to detect the survival rate after treated with different concentrations of PPⅥ [0 (control group), 1, 2, 4, 8, 16, 32, 64 μmol/L] for different time (24, 48, 72 h). The clone formation experiments were adopted to detect the number of cell clones and clone formation rate after being treated with different concentrations of PPⅥ [0 (control group), 2, 4, 8 μmol/L] for 14 days. The flow cytometry and Western blot assay were used to detect the apoptotic rate of cells, the expressions of apoptosis-related protein [B cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), cleaved caspase-3], and the expressions of related proteins of Fas/Fas ligand (FasL) death receptor pathway and protein kinase B (Akt)/glycogen synthesis kinase-3β (GSK-3β) pathway after being treated with different concentrations of PPⅥ [0(control group), 4, 8 μmol/L] for 24 h.
RESULTS
2
Compared with the control group, the survival rate of cells, the number of clones and clone formation rate, the protein expression of Bcl-2, and the phosphorylation levels of Akt and GSK-3β protein were decreased significantly in different concentration groups of PPⅥ (
P
<0.05 or
P
<0.01). The apoptotic rate, the protein expressions of Bax, cleaved caspase-3, Fas, FasL and cleaved caspase-8 were increased significantly (
P
<0.05 or
P
<0.01).
CONCLUSIONS
2
PPⅥ can inhibit the proliferation and induce the apoptosis of human glioma LN229 cells, which may be related to the activation of the Fas/FasL death receptor pathway and the inhibition of the Akt/GSK-3β pathway.
