A schematic overview of the mechanism of anticancer effect of resveratrol against brain tumor. Resveratrol exhibits both chemopreventive (via antiproliferative, anti-metastatic, anti-invasive, anti-inflammatory, anti-angiogenic effects) and chemotherapeutic effects (via apoptotic induction) by regulating several signaling events. In addition, it can simultaneously endorse chemo- and radio-sensitization to improve therapeutic efficacy. Red arrows indicate downstream events and red lines indicate inhibition.
