Abstract
Purpose
Cisplatin-based chemotherapy is a primary alternative for treating bladder cancer. But drug resistance and various side effects are the main unsightliness challenges. In search of a novel chemotherapeutic approach, this study was conducted to investigate whether thymoquinone (TQ) chemosensitize 5637 bladder cancer cells to cisplatin (CDDP).
Methods
The IC50 for each drug was first determined. The cells were then pre-exposed to 40 µM of TQ for 24 h before being treated with 6 µM of cisplatin. The viability and the sub-G1 population of the 5673 cells were respectively evaluated by alamar blue assay and propidium iodide staining. RT-qPCR was also applied to analyze the expression profile of the apoptosis-related genes (Bax, Bcl-2, p53).
Results
The viability of the cells treated with the combination of TQ and CDDP was significantly decreased compared to CDDP- or TQ-treated cells. TQ at the concentration of 40 µM increased the cytotoxicity of 6 µM CDDP by 35.5%. Moreover, flow cytometry analysis indicated that TQ pre-treatment of the cells resulted in a 55.5% increase in the population of 5637 cells in the sub-G1 phase compared to cells treated with CDDP alone. The results from RT-qPCR exhibited that the exposure of the cells to both TQ and CDDP significantly elevated Bax/Bcl-2 ratio by down-regulating Bcl-2 expression.
Conclusion
TQ significantly increased the cytotoxicity of CDDP in 5637 cells and induced apoptosis by down-regulation of the Bcl-2. Therefore, TQ and CDDP might be an effective therapeutic combination for TCC bladder cancer treatment.
