MMP9 and non-small cell lung carcinoma: To investigate the mechanism by which morin inhibits NSCLC migration and invasion, we examined the expression of invasive proteins (MMP-2, MMP-9, u-PA, u-PAR, and MT1-MMP) and EMT markers (fibronectin, N-cadherin, and vimentin) in LPS+ATP-stimulated NSCLC cells.
