Betulinic acid-(BA) has apoptotic effects on neuroblastoma. This study explored the effects of cisplatin-(CP), BA and combination of BA and CP (BA-CP) on cell proliferation, apoptotic cell death and expressions of metastasis related genes in neuroblastoma. In this study, N-MYC positive and negative neuroblastoma cell lines, KELLY and SHSY5Y, were treated with BA, CP and BA-CP combinations. BA-CP combinations showed synergistic activity on cell growth inhibition and apoptotic cell death in both neuroblastoma cell lines. In SHSY5Y cells BA, CP or BA-CP treatments induced downregulation most of the metastatic genes' expressions. In KELLY cells, while CP treatment decreased some metastatic gene expressions, BA or BA-CP treatment reduced only DENR and RB1. BA and BA-CP showed prominent effect on metastasis related gene expressions in predominantly KELLY cells. The results of this study suggest that BA may be a promising anti-cancer agent for neuroblastoma treatment, whereas CP is still the most suitable chemotherapeutic drug for aggressive neuroblastoma.
