Effect of 24-h statin incubation on the resting free calcium concentration. "Control" represents the mean fluorescence ratio (FR) of control cells and was set to 1. The other entries are FR values normalized to the mean FR of the respective control cells. The type of incubation, the SEM values as well as the number of analyzed cells (n) are indicated. The last line shows experiments in which human SH-SY5Y neuroblastoma cells were incubated for 24 h with 10 μM cerivastatin. All other experiments were performed with HUVEC cells.
