PC12 cell viability, cellular Ca²⁺ concentration and caspase- 3 activity were determined after hypoxia stimulation for 24 h with the preincubation of CsA and ATR. (A) Effects of salidroside on cell viability of hypoxia-induced PC12 cells with the preincubation of CsA and ATR; (B) Effects of salidroside on cellular Ca²⁺ concentration of hypoxia-induced PC12 cells with the preincubation of CsA and ATR; (C) Effects of salidroside on c caspase 3 activity of hypoxia-induced PC12 cells with the preincubation of CsA and ATR.
