Resveratrol reduces TNF-α-induced U373MG human glioma cell invasion through regulating NF-κB activation and uPA/uPAR expression.

Background: High invasiveness of glioma cells is one of the reasons that patients with malignant glioma have a poor prognosis. Resveratrol, a plant compound abundant in the peel of grapes, has been suggested as a potential cancer chemopreventive agent. Therefore, we investigated the effect of resveratrol on glioma cell invasion.

Materials And Methods: The effect of resveratrol on U373MG human glioma cell invasion was assessed by Matrigel assay and methylthiazoltetrazolium assay. Western blotting and reverse transcription-polymerase chain reaction were performed to elucidate the action mechanism of resveratrol.

Results: Resveratrol reduced tumor necrosis factor (TNF)-α-induced U373MG human glioma cell invasion. In addition, resveratrol repressed nuclear factor kappa B (NF-κB) activation and down-regulated mRNA expression of urokinase plasminogen activator (uPA) and its receptor in TNF-α-treated glioma cells.

Conclusion: These findings suggest that resveratrol could prevent glioma cell invasion via inhibiting proteolysis of extracellular matrix.
