摘要
Objective:In this study,the aim was to investigate the inhibitory effect of 6,6’-bieckol on the migration and epithelial-mesenchymal transition(EMT)of non-small cell lung cancer(NSCLC)cells,and explore its potential molecular mechanisms.Methods:Cell migration was measured using a CCK8,wound healing,and transwell migration assay.Apoptosis was determined using an Annexin V/propidium iodide staining.Western blotting and immunofluorescence were used to examine the expression level of apoptosis-related proteins and EMT marker proteins.Results:The results showed that 6,6’-bieckol inhibited migration and induced apoptosis of NSCLC cells.Furthermore,6,6’-bieckol had significantly up-regulated the E-cadherin and down-regulated Snail1 and Twist1 transcriptional levels.6,6’-Bieckol might inhibit TGF-β-induced EMT by down-regulating Snail1 and Twist1 and up-regulating E-cadherin in lung cancer cells.Conclusion:It is suggested that 6,6’-bieckol has the potential to be developed as a therapeutic candidate for lung cancer.
