OGD/R promotes the increase in tyrosine phosphorylation of the NMDAR NR2A subunit in differentiated SH-SY5Y cells. Immunoprecipitation and immunoblotting of lysates prepared from differentiated SH-SY5Y cells subjected to OGD/R reveals a significant increase in tyrosine phosphorylation of the NR2A subunit. (A) Western blot shown is representative of three independent experiments. (B) Quantification of the relative densitometry of the phospho-Tyr-NR2A immunoreactive band. Data represent fold change of OGD/R groups compared to normoxic control group (arbitrary units) ± S.E.M from three separate experiments. (askteriks * indicates a p <0.01 from normoxic control; ANOVA with post hoc Bonferroni test).
