MMP14 and glioblastoma: Recently, Huang et al. provided evidence that MET mediates endothelial plasticity, in which the MET/ETS-1/matrix metalloproteinase-14 (MMP-14) axis controls VE-cadherin degradation, endothelial–mesenchymal transition, and vascular abnormality, driving aberrant vascularization and chemoresistance in glioblastoma [69].
