Objective
2
To investigate the effect of piceatannol (PIC) on the proliferation, apoptosis and cell cycle of MDA-MB-468 triple negative breast cancer cells and its mechanism.
Method
2
The methylthiazolyldiphenyl-tetrazoliu bromide (MTT) colcorimetry method was used to investigate the effect of different concentrations of PIC (0, 2.5, 5.0, 10.0, 20.0, 40.0, 80.0, 160.0 μmol·L
-1
) on the cell viabilities of triple negative breast cancer MDA-MB-468 cells and calculate the half maximal inhibitory concentration (IC
50
) value, the effect of different concentrations of PIC (5.0, 10.0, 20.0 μmol·L
-1
) on the cell cycle of MDA-MB-468 were investigated by flow cytometry with propidium iodide (PI) staining. The apoptotic effect of PIC (5.0, 10.0, 20.0 μmol·L
-1
) on MDA-MB-468 cells in triple negative breast cancer was investigated by flow cytometry with cell apoptosis detection Annexin V-FITC and PI double staining. Western blot was used to investigate the effect of different concentrations of PIC (5.0, 10.0, 20.0 μmol·L
-1
) on the proliferation and apoptosis of MDA-MB-468 cells and detect the expressions of secreted glycoprotein Wnt/
β
-catenin pathway related proteins.
Result
2
MTT results showed that compared with the blank group, PIC could inhibit the proliferation of MDA-MB-468 cells in a concentration-dependent manner (
P
<
0.05,
P
<
0.01), with IC
50
at(39.4±4.6)μmol·L
-1
. Compared with the blank group, PIC could increase the percentage of MDA-MB-468 cells in G
0
/G
1
phase about cell cycle in a concentration-dependent manner (
P
<
0.01). Compared with the blank group, 5.0, 10.0, 20.0 μmol·L
-1
PIC could induce apoptosis of MDA-MB-468 cells for 48 h(
P
<
0.01), and the apoptosis rate of MDA-MB-468 cells reached 49.87% when treated with 20.0 μmol·L
-1
for 48 h. Compared with the blank group, PIC could significantly reduce the expressions of
β
-catenin, proto-oncogene (C-myc) and adhesion factor (CD44) proteins in MDA-MB-468 cells, significantly inhibit the phosphorylation of
protein kinase B (Akt) and p38 mitogen activated protein kinase (p38 MAPK) proteins and the protein expression of B lymphocyte tumor-2 (Bcl-2), and enhance cysteine aspartic acid protease-3 (Caspase-3), Bcl-2 related X protein (Bax) and phosphorylated
β
-catenin protein expression(
P
<
0.01).
Conclusion
2
PIC may inhibit the proliferation of MDA-MB-468 cells by inhibiting the Wnt/
β
-catenin signaling pathway, block the cell cycle in G0/G1 phase, and induce its apoptosis.
