Inhibitions and mechanisms of amygdalin in non-small cell lung cancer NCI-H1299 cell line invasion in vitro

The aim of this study was to investigate the effects and mechanisms of a nature product, amygdalin, in non-small cell lung cancer NCI-H1299 cell line invasion and migration in vitro. NCI-H1299(H1299)cells were treated with amygdalin. MTS assay was employed to determine cell proliferation, transwell chamber and wound-healing assay were employed to determine invasion and migration in vitro, western blotting and RT-PCR assay were employed to determine the expression of integrin β1, integrin β4, integrin-linked kinase(ILK), focal adhesion kinase(FAK), p-FAK and β-catenin, and the phosphorylation of Akt and RICTOR. Results showed that in vitro proliferation of H1299 cells were inhibited significantly after treated with 0. 5 and 1 mg/mL amygdalin for 48 h. The invasion and migration potential was decreased. The protein and mRNA expression of MMP-2/9, integrin β1/4, ILK, FAK, β-catenin, the activity of MMP-2/9, the phosphorylation of FAK, Akt and RICTOR were all decreased significantly(all of P< 0. 05).
