Propofol Protects Hippocampal Neurons from Hypoxia-Reoxygenation Injury by Decreasing Calcineurin-Induced Calcium Overload and Activating YAP Signaling

Figure 4

Propofol induced dephosphorylation and nuclear translocation of YAP in HT-22 cells. (a) HT-22 cells were starved for 16 hr, then treated with propofol (15 μmol/l) for different times or with different concentrations of propofol for 4 hr. Western blots were used to analyze the expression of phosphorylated YAP and total YAP. Representative results are shown from three independent experiments. ^a versus 0 min, ^b versus 0 min. (b) Propofol-induced (15 μmol/l for 4 hr) YAP nuclear translocation is shown in starved HT-22 cells by immunofluorescence staining and Western blots. Green: YAP; blue: DAPI. (c) Starved HT-22 cells treated with 15 μmol/l propofol for 12 hr, then mRNA and protein levels of survivin and Bcl2 were detected by real-time PCR and Western blot. ^a versus control.
