Figure Lengend Snippet: mGlu 2/3 receptor ligands regulate expression of phosphorylation of Fyn/N-methyl-D-aspartate receptors (NMDAR) in acute 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mice models. Immunoblots and relevant histograms show expression of phosphorylated NMDAR subunit GluN2A at Tyr1325 (A, B), GluN2B at Tyr1472 (B, C), Fyn at Tyr416 (D, F) in substantia nigra (SN) of acute MPTP-treated mice with different doses of LY354740. The band intensity of particular target proteins was normalized to GluN2A, GluN2B or Fyn levels. * p < 0.05, ** p < 0.01. N = 4. Western blots represent the expression of phosphorylated NMDAR subunit GluN2A at Tyr1325 (G, H), GluN2B at Tyr1472 (G, I) and Fyn at Tyr416 (E, J) in acute MPTP-treated mice with saline, LY341495 or LY354740. The band intensity of particular target proteins was normalized to GluN2A, GluN2B or Fyn levels. * p < 0.05, ** p < 0.01 vs. the other two groups. N = 3. Data in (B, D) were expressed as % of the normal + saline group, and data in (E, G) were expressed as % of the MPTP + saline group. Error bars represent SEM.
