Figure 2. Effect of simvastatin on cellular CoQ10 levels and cytotoxicity. Viability (A) and CoQ10 content and oxidative status (B) of human dermal fibroblasts with different doses of simvastatin for 72 h. Data (n=9 A; n=4 B) are reported as mean and standard error of % live cells (A) and coenzyme Q10/total protein (μg/mg) (B). Significance difference vs 0 nM + p<0.05, ++ p<0.01, +++ p<0.001, ++++ p<0.0001.
