We have targeted the urokinase-type plasminogen activator receptor (uPAR) with phosphorothioate antisense oligonucleotides (aODN) in vitro to evaluate the anti-invasive and anti-proliferative effects of uPAR down-regulation, as well as in vivo to evaluate anti-tumor and anti-metastatic activity. aODN-dependent uPAR downregulation in vitro was induced in cells of human melanoma, mammary carcinoma, ovarian carcinoma and SV-40-transformed embryonic lung fibroblasts. uPAR was determined by an antibody-based assay and by semiquantitative polymerase chain reaction. Cell invasion was evaluated by Matrigel invasion assay and cell proliferation by direct cell counting. aODN reduced uPAR, invasion and proliferation in all the treated cell lines. Following aODN treatment, human melanoma cells exhibited a strong decrease of uPAR-dependent ERK1/2 activation and were used in vivo to control metastasis in CD-1 male nude (nu/nu) mice by uPAR aODN injection. 60 mice were injected in the hind leg muscles with a suspension of 10(6) melanoma cells. After 4 days, when a tumor mass of about 350 mg was evident in all the mice injected, 20 mice were treated i.v. with aODN and 20 with dODN at 0.5 mg/day for 5 consecutive days. Twenty control mice were not treated. A second and third cycle of treatment was administered at 2-day intervals. Treatment with aODN resulted into a 78% reduction of lung metastases and 45% reduction of the primary tumor mass with no loss of body weight. Our results suggest to evaluate the utility of uPAR aODN in controlling the metastatic spreading of human melanoma.
