GRP78 Promotes Neural Stem Cell Antiapoptosis and Survival in Response to Oxygen-Glucose Deprivation (OGD)/Reoxygenation through PI3K/Akt, ERK1/2, and NF-κB/p65 Pathways

Figure 3

Role for GRP78 in OGD/reoxygenation-induced PI3K/Akt and ERK1/2 activations. (a) Protein expression of GRP78 in GRP78 knocked-down NSCs with OGD/reoxygenation induction, for siRNA transfecting efficiency determination. (b–d) Abolished phosphorylation of PI3K, Akt, and ERK1/2 by OGD+R induction in GRP78 knocked-down NSCs. GAPDH was used as an internal loading control. and were considered to be significantly different in Neg-siRNA-control versus Neg-siRNA-OGD+R, Neg-siRNA-control versus GRP78-siRNA-control, and GRP78-siRNA-control and GRP78-siRNA-OGD+R groups. .
