Abstract:
Objective: To observe the effect of Juglone on invasion and metastasis of Hela cells and explore the possible mechanism. Methods: HeLa cells were cultured and treated with 10,20,50,100μmol/L Juglone for 24 hours. The morphology changes of HeLa cells were observed with an inverted microscope. The viability of HeLa cells was detected by MTT assay. The cell scratch test was used to detect cell migration ability after treatment of Juglone. The ability of cell invasion was measured by Transwell chamber. The expression of matrix metalloprateinases (MMP)-2 and MMP-9 were detected by Western blotting. Results: Compared with control group, the viability of HeLa cells decreased after treatment with different concentrations of Juglone for 24 hours, and the cell morphology was changed in a dose-dependent manner. Scratch test results showed that the level of cell movement ability decreased significantly with the increase of the concentration of Juglone. Transwell invasion assay showed that Juglone had a strong inhibitory effect on the invasiveness of HeLa cells in vitro. Western blotting results showed that Juglone inhibited the expression of MMP-2 and MMP-9 protein in HeLa cells. Conclusion: Juglone can inhibit the invasion and metastasis in HeLa cells, and its possible mechanism may be related to down regulating the expression of MMP-2 and MMP-9.
