Abstract
|
[Objective] To observe the impacts of sulforaphane on proliferation, apoptosis and PI3K/Akt pathway of human colon cancer HT-9 cells.[Methods] The effects of sulforaphane on proliferation of HT-9 cells were investigated using CCK8 assays. The HT-9 cells apoptosis was analyzed by flow cytometry with propidium iodide staining. The expression levels of related proteins in PI3K/Akt pathway and apoptosis proteins were analyzed by Western Blot.[Results] Sulforaphane can significantly suppress proliferation of HT-9 cells in a time-and dose-dependent manner. Propidium iodide staining showed that the apoptosis of HT-9 cells was stimulated by sulforaphane. After treated with 10, 20, 40 μg/mL of sulforaphane for 24 h, the apoptosis rates were (14.67±1.95)%, (27.95±2.53)% and (35.6±3.75)%, respectively. Sulforaphane downregulated the expression levels of PI3K, p-Akt and Bax proteins and upregulated the expression of Bax protein in a dose-dependent manner.[Conclusion] Sulforaphane can significantly suppress the proliferation of HT-9 cells and stimulate apoptosis, the mechanism may be associated with the inhibition of PI3K/Akt signaling pathway. |
