RESUMO
Objective To investigate the molecular mechanism of luteolin-regulated epithelial-mesenchymal transition (EMT) in non-small cell lung cancer. Methods Firstly,the potential target of luteolin was studied by molecular docking.The effect of luteolin on EMT markers was analyzed,and then molecular biology experiments were used to verify the results. Results The result of molecular docking showed that luteolin had a good docking effect on the integrin family,of which the lowest binding energy was -15.11 in docking with Integrin αIIbβ3.The result of flow cytometry showed that luteolin could down-regulate the expression of integrin induced by hypoxia. Conclusion Luteolin can regulate integrin expression,which suggested that luteolin can regulate EMT through integrin.This conclusion may provide new methods in prevention of tumor metastasis for traditional Chinese medicine.
RESUMO
Epithelial mesenchymal transition ( EMT) is one of the important biological processes in tumor invasion and metastasis . However , due to the complexity of EMT signaling pathway and its unclear molecular mechanism , the treatment of EMT is still a worldwide problem .But many studies have proved that EMT is not an irreversible process .In recent years , the research of FOX gene family in EMT shows its important role in tumor metastasis . This review focuses on the FOX-mediated EMT process in many kinds of tumor , aiming to have a better understanding of EMT signaling network , and provide a new target for the effective pre-vention of EMT .
