Impact of histone deacetylase inhibitor valproic acid on the anticancer effect of etoposide on neuroblastoma cells.
OBJECTIVES: Etoposide (Vepesid, VP-16), an inhibitor of topoisomerase II, is a chemotherapeutic drug commonly used for treatment of different types of malignant diseases. By inhibiting the topoisomerase II enzyme activity in cancer cells, this drug leads to DNA damage and subsequently to cell death. In this study, we investigated the ef.....
