Interaction of curcumin on cisplatin cytotoxicity in HeLa and HepG2 carcinoma cells

Abstract

Background and Aims: Our study aimed to evaluate how curcumin affect cisplatin cytotoxicity in human cervical carcinoma (HeLa), human hepatocellular carcinoma (HepG2), and Chinese hamster lung fibroblast (V79) cells. Methods: The cytotoxicity was evaluated by MTT assay. Results: The IC 50 values of curcumin were 404 μM and 320 μM in HeLa cells; 236 μM and 98.3 μM in HepG2 cells; 877 μM and 119 μM in V79 cells; for 24 h and 48 h, respectively. The IC 50 values of cisplatin were 22.4 μM and 12.3 μM in HeLa cells; 25.5 μM and 7.7 μM in HepG2 cells; 15.4 μM and 4.9 μM in V79 cells; for 24 h and 48 h, respectively. Curcumin significantly decreased cisplatin cytotoxicity at 500 μM in HeLa cells and above 250 μM and 125 μM in HepG2 cells, for 24 h and 48 h, respectively. In V79 cells, curcumin significantly decreased the IC 50 values of cisplatin above 500 μM and 125 μM for 24 h and 48 h. Conclusion: The results might contribute to the anticancer effect of the curcumin-cisplatin combination in cervical and he-patocellular carcinoma, but in order to support this result and determine its interactions with antineoplastic drugs, further studies are needed.
