Abstract: In this study we have examined the antitumor effect of combined administrations of indomethacin (IND) with doxorubicin (DOX) on growth of K-562 leukemia cells. Although, as single drug treatment, only high concentrations of IND reduced growth (>200 µM) and induced apoptosis (>800 µM) of the K-562 cells, a synergistic effects on DOX-induced cell growth inhibition, apoptosis and differentiation were observed during the co-administration of DOX with 10 µM IND. Cells treated with this combination had elevated GSHt level compare to DOX-treated cells. Modulation of GSHt level of DOX-treated cells with Cd2+ ions or BSO confirmed its important role in processes of DOX-induced differentiation. Results of this study showed that IND has a positive effect on therapeutic efficacy of DOX, and could be a perspective modulator in cancer chemotherapy.
