Fig 2. Cell viability in BON1 cells: BON1 cells were pre-treated with lovastatin for 24h before everolimus was added, and the combination of both drugs was incubated for 48h (A) or 120h (B).

Fig 2

The single drugs were incubated for the same time as in combination. The mean percentage of cell viability, relative to the untreated control, ± SEM (error bars) is shown. (A) Treatment with 5–10 μM lovastatin had no significant effect on BON1 cell viability. Treatment with 20 μM lovastatin or with 10 nM everolimus alone significantly decreased BON1 cell viability. There was no additive effect of both drugs. (B) Treatment with 5–10 μM lovastatin had no significant effect on BON1 cell viability. Treatment with 20 μM lovastatin or with 10 nM everolimus separately significantly reduced BON1 cell viability; combination treatment showed no additive effect. * P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001 (compared to the control); @ P ≤ 0.05, @@ P ≤ 0.01, @@@ P ≤ 0.001 (combination compared to each drug separately).
