Figure 7. Knockdown of MST1 triggered YAP nuclear translocation. (A) Western blotting analysis of MST1 expression in ctrl, si-NC, and si-Nrf2 transfected astrocytes. (B) The results of densitometric analysis of the bands were plotted as mean ± SD (n = 4). Over 80% of MST1 expression was suppressed by si-MST1. **p < 0.01 compared with ctrl group. (C) Immunofluorescence staining of ctrl, si-NC, si-MST1 treated astrocytes with anti-YAP (green). The siRNA was labeled with fluorophore Cy3 (red) to show the transfected cells. The cell nuclei were counterstained with DAPI (blue). Bar = 50μm. (D, E) Western blotting analysis of cytoplasmic and nucleus extraction samples from control, si-NC, si-MST1 transfected astrocytes with anti-YAP. GAPDH and H3 were used as a loading control for cytoplasmic and nucleus protein, respectively. The histogram showing the results of densitometric analysis of nucleus/cytoplasmic YAP expression in ctrl, si-NC, si-MST1 transfected astrocytes. The results were normalized to control plotted as mean ± SD (n = 4). Si-MST1 significantly increased YAP nuclear expression. *p < 0.01 compared with control.
