Glycine-GluN1 binding antagonist and Akt inhibitor attenuate the effect of glycine in reducing the infarct volume after glycine receptors and the channel activity of NMDARs are inhibited. (A) Sample images of TTC strained-brain sections collected at 24 h after ischemia onset. Glycine (100 µg/100 g, icv) was administered at 3 h following I/R. Glycine-GluN1 binding antagonist L-689560 (L68; 0.1 mg/100 g, ip) or Akt inhibitor IV (100 µM, 2 µl, icv) is injected with MK-801 and strychnine at 30 min before glycine injection. (B) Summarized quantification data indicate that glycine-GluN1 binding antagonist and Akt inhibitor treatment attenuate the effect of glycine in reducing the infarct volume after glycine receptors and NMDARs are inhibited (n = 6, ANOVA test, *P < 0.05 vs. I/R + Stry + MK; # P < 0.05 vs. I/R + Stry + MK + Gly). Stry: Strychnine; Gly: glycine; MK: MK-801.
