Abstract
Purpose: To evaluate the synergistic cytotoxicity of sodium dichloroacetate (DCA) in combination with cisplatin (CIS) against human cervical cancer cell lines.
Methods: Cervical cancer SiHa and HeLa cells and normal cells (Hek-293, Vero, peripheral blood mononuclear and human erythrocytes) were treated in vitro with DCA and CIS individually or their combination. Cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method while hemolytic activity was evaluated from the released hemoglobin. Half-maximal inhibitory concentration (IC50) of DCA or CIS was obtained.
Results: The combination of DCA + CIS decreased the cell viability of SiHa, Hek-293, Vero, and PBMC cells, but not of Hela cells (p < 0.05). Furthermore, the individual treatments alone or in combination did not cause significant hemolysis (p < 0.05).
Conclusion: The combination of DCA + CIS increases the damage caused by CIS alone on SiHa cells. It also decreases the cell viability of Hek-293 and Vero without affecting peripheral blood mononuclear and human erythrocyte integrity. The results suggest that the combination of DCA and CIS can induce synergistic antitumor effect in different types of cancer cell lines. However, further studies are required to determine the biological effects of the combination of DCA and CIS in vivo.
