Abstract:

The effects of inhibition of transcription factor AP-1 on synthesis of urokinase type Plasminogen Activator (uPA), uPA Receptor (uPAR), and Vascular Endothelial Growth Factor (VEGF) were determined using cultured salivary gland carcinoma cells (ACCS and ACCT cells). The expression of uPA, uPAR and VEGF was induced in the presence of EGF. To inhibit AP-1 activation, we
transfected double-stranded synthetic oligonucleotides containing the binding sequence of AP-1 (AP-1 decoy ODNs) using a novel, hemagglutinating virus of Japan-, liposome method. Transfection of AP-1 decoy ODNs into ACCS and ACCT cells inhibited EGF-induced uPA and uPAR mRNA expression. AP-1 decoy ODN transfection reduced the in vitro invasion activity of both cells in the presence of EGF to 27.0 and 39.4%, respectively. EGF-induced mRNA expression of VEGF was simultaneously suppressed by AP-1 decoy ODNs. Inhibition of AP-1 by decoy ODNs has potential as a novel method for the simultaneous inhibition of salivary gland carcinoma cell invasion and angiogenesis.
