Ellagic acid, a polyphenolic compound found in berries, fruits and nuts, has been shown to possess growth-inhibiting and apoptosis promoting activities in cancer cell lines in vitro. The objective of this study was to investigate the effect of ellagic acid in human neuroblastoma SH-SY5Y cells. In cultures of SH-SY5Y cells incubated with ellagic acid, time- and concentration-dependent inhibitory effects on cell number were demonstrated. Ellagic acid induced cell detachment, decreased cell viability and induced apoptosis as measured by DNA strand breaks. Ellagic acid-induced alterations in cell cycle were also observed. Simultaneous treatment with all-trans retinoic acid did not rescue the cells from ellagic acid effects. Furthermore, the results suggested that pre-treatment with all-trans retinoic acid to induce differentiation and cell cycle arrest did not rescue the cells from ellagic acid-induced cell death.
