dc.description.abstractAnti-Proliferative Effect of Copper Tolfenamic Acid in Neuroblastoma Cell Lines Sarah Grebennikov, Yazmin Hernandez, Rajasekhar Maram, Umesh T. Sankpal, and Riyaz Basha Background:Neuroblastoma (NB) is a neuroendocrine tumor of the sympathetic nervous system most commonly found in the adrenal medulla. It is the most common extracranial tumor in infants with an average age of onset of 1 year. While presentation in children over the age of 5 is rare, the prognosis is markedly worse due to the higher likelihood of an aggressive malignancy with metastasis to lymph nodes and bone marrow. Current treatment modalities include surgical resection, chemotherapy, radiotherapy, and autologous stem cell transplant. These treatments are highly efficacious, however there are several associated side effects. Specifically, chemotherapeutic side effects are dose dependent and can range from mild stomach pain to more severe and serious complications including hearing loss, myelosuppression, and neurotoxicity. To limit these side effects, we are investigating anti-cancer agents with limited side-effects. Copper Tolfenamic Acid (Cu-TA) is metallic complex of an anti-cancer Non-Steroidal Anti-inflammatory Drug, Tolfenamic acid which is known to inhibit anti-apoptotic protein, Survivin and inhibits cancer cell growth. Hypothesis: We hypothesize that Cu-TA down-regulates survivin and inhibits neuroblastoma cell growth more effectively than TA. Methods: NB cell lines, SMS-KCNR and LA155n cell lines (from ATCC) were treated with increasing concentrations of Cu-TA or TA (0, 5, 10, 20, 40 and 80 µM). CellTiter-Glo reagent was added to the 96-well plate, and readings were taken at 24 and 48 hours. Using this data, IC50 values were calculated using SigmaPlot software. The effect of Cu-TA on Survivin protein expression was measured using western blot analysis. Results: Cell viability data showed a dose dependent decrease due to Cu-TA treatment in both cell lines. Analysis of the Western Blot confirms that there was a decrease in the survivin protein in the cells treated with Cu-TA. Conclusion:These results demonstrate that Cu-TA is an inhibitor of survivin and more effective at inhibiting NB cancer cells than TA alone. Since survivin is associated with resistance to chemotherapy, if Cu-TA sensitizes NB cells to chemotherapy, it will help reduce the side effects of chemotherapy while maintaining the efficacy of treatment.
