RESUMO

<p><b>OBJECTIVE</b>To investigate the effect of sunitinib on the migration of ovarian cells and its mechanism of the negative regulation TGF-β mediated of epithelial-mesenchymal transition(EMT) by sunitinib to inhibit ovarian cancer metastasis.</p><p><b>METHODS</b>The migration of human ovarian cancer cells SKOV3 was evaluated by wound-healing and transwell assays. The effects of sunitinib on TGF-β-induced E-cadherin expression was assessed by Western-blotting, real time RT-PCR and immunofluorescence assay. The protein levels of Snail and the transcriptional activity of Smad in sunitinib-treated cells were examined by Western-blotting and SBE-luciferase assay.</p><p><b>RESULTS</b>Sunitinib suppressed the migration of SKOV3 cells in a concentration-dependent manner. TGF-β stimulation reduced E-cadherin protein level, which was attenuated by sunitinib. Sunitinib inhibited the up-regulation of Snail protein level induced by TGF-β treatment. The SBE reporter was constructed by linking the Smad-binding elements promoter upstream of luciferase reporter gene. A remarkable increment of transcriptional activity of Smads complexes was observed in SKOV3 cells exposed to TGF-β, which was significantly prohibited by sunitinib.</p><p><b>CONCLUSION</b>Sunitinib can inhibit the migration of SKOV3 cells and attenuate the down-regulation of E-cadherin protein level induced by TGF-β. Sunitinib can abolish TGF-β-induced up-regulation of Snail protein and decrease the transcriptional activity of Smad complexes. The results indicate that sunitinib suppresses migration of ovarian cancer cells through negative modulation of TGF-β-mediated epithelial-mesenchymal transition.</p>
