Cell viability of MCF7 cells exposed to doxorubicin and oxaliplatin (24 h incubation) in the presence of 6-selenocaffeine as evaluated by the MTT assay. Values represent mean ± SD and are expressed as percentages relative to non-treated control cells. (A) Effect of 6-selenocaffeine on the viability of cells treated for 24 h (n = 6); (B) Effect of 6-selenocaffeine on the viability of cells treated with doxorubicin for 24 h (n = 3); (C) Effect of 6-selenocaffeine on the viability of cells treated with oxaliplatin for 24 h (n = 3) (** p < 0.01 when compared with MCF7 cells treated only with oxaliplatin).
