The expression of key members of PI3 K/Akt pathway in NPC cells. a Western blot showed the expression levels of p-Akt(S473)/Akt and p-FAK(Y397)/FAK in NPC cells transducted by GFP-RACK1 plasmid or GFP-Tag control plasmid. d The expression of p-Akt(S473)/Akt and p-FAK(Y397)/FAK in 5–8F and CNE1 cells was measured by western blot after transfected with RACK1 siRNA or unspecific scrambled siRNA. GAPDH served as the internal control. b, c, e, f Densitometry quantifications were performed for three independent experiments. The data were shown as the mean ± sem Student’s t-test, (*P < 0.05, **P < 0.01)
