Abstract
Resveratrol, polyphenol naturally occurring in grapes or nuts, has anti-cancer properties in the treatment of neuroblastoma- the most common childhood solid tumor. It affects cancer cells by increasing apoptosis, inducing cell necrosis and reducing tumor mass. Mechanism of action- (1) converting procaspases, mainly procaspases three and nine into active forms- caspases, (2) blocking kinases, and also (3) leading the cell to the S-cell cycle, where it is most effective while increasing the concentration of cyclin E and lowering the concentration of p21 protein. Invitro, as well as, rodent animal models studies are available and show promising results. Therapeutic doses, currently within 10-100μmol/L, are also being tested, as well as other forms of resveratrol, such as its trans-4,4'-dihydroxystilbene analog and polyphenol lipoconjugates. In our review, we presented the known molecular mechanisms of polyphenol anti-tumor activity against neuroblastoma and discussed the studies confirming its effectiveness.
