Purpose: To identify the role of baicalein in human cervical cancer and to determine whether baicalein treatment affects hedgehog/Gli signaling pathway.
Methods: Cell proliferation was evaluated by MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and colony formation assays. Cell death rate was assessed by PI-staining and FACS assay. Furthermore, cell invasion was assessed by Transwell assay while the levels of the key proteins were measured by western blotting analysis.
Results: Baicalein suppressed the viability and proliferation of HeLa cells. The colony formation ability and relative migration rate were significantly decreased in the HeLa cells treated with 50 μM baicalein. Furthermore, the levels of Shh, Gli1, MMP-9, and VEGF declined significantly in baicalein-treated cells.
Conclusion: The results demonstrate that baicalein inhibits the growth and invasiveness of cervical cancer cells partly by suppressing the activation of hedgehog/Gli signaling pathway in a concentrationdependent manner.
