MEK5 expression drastically increased MMP-9, but not MMP-2 mRNA expression. Luciferase report assays suggest that the -670/MMP-9 promoter is upregulated by MEK5 and electromobility shift assay further suggests the involvement of activator protein-I (AP-1). Using an AP-1 luciferase construct, activation of MEK5 was confirmed to enhance AP-1 activities up to twofold.
