Abstract

To elucidate the role of E-cadherin in matrix metalloproteinases (MMPs) expression, we transfected to squamous carcinoma cells with E-cadherin cDNA. HN5 cells and mock-transfected HN5-neo cells expressed proMMP-2 and active MMP-2. E-cadherin-transfected HN5-EC cells produced comparable proMMP-2 but low active MMP-2; and membrane type 1-MMP (MT1-MMP) mRNA declined. Phosphorylated ERK, a marker of mitogen-activated protein (MAP) kinase cascade, also declined in HN5-EC cells. The addition of anti-E-cadherin antibody resulted in the disappearance of these alterations in HN5-EC cells. These results suggest that E-cadherin suppresses MAP kinase cascade and down-regulates MT1-MMP.
