Abstract:
Objective To explore the effect of galangin on the inhibition of proliferation and invasion in human lung cancer A549 cell lines and its mechanism thereof. Methods MTS assay was employed to detect the ability of cell proliferation with different concentrations (0, 5, 10, 20, 40, 60 and 100μmol/L) of galangin after A549 cells were cultured in 96 well-plate. Transwell assay was employed to detect the ability of cell invasion. Western blot assay was employed to detect the protein expression levels of Survivin, p27, CD44, ICAM, MMP-2/9 and the phosphorylation of PI3K and AKT. Results The cell proliferation rate of A549 cell line was suppressed with increased concentration of galangin treatment, and IC50 was 44.7μmol/L. The concentrations of 10μmol/L and 20μmol/L were used for the following study. The ability of cell invasion was decreased with 0, 10 and 20μmol/L concentrations of galangin treatment (P<0.05). The protein expression of p27 was increased and the expressions of other proteins were decreased with 0, 10 and 20μmol/L galangin treatmenmt (P<0.05). Conclusion Galangin can significantly inhibit the cell proliferation and invasion of human lung cancer A549 cell line, and which is a potential anti-lung cancer drug. The mechanisms may be related with the regulated related gene expression and the inhibited phosphorylation of PI3K and AKT.
