Expression of 2-amino-3-(3-hydroxy-5-methyl-isoxazol-4-yl)propanoic acid (AMPA) receptor subunits in the plasma membrane of the CA1 region. Seven- to nine-week old CD-1 wild-type or EAAT3 knockout mice were subjected to the fear conditioning stimuli. Their CA1 regions were harvested before the stimuli, 30 min or 180 min after the stimuli for Western blotting of AMPA subunits (GluR1, GluR2, GluR3 and GluR4, panels A–D). A representative Western blot is shown in the top of each panel and a graphic presentation of the GluR protein abundance quantified by integrating the volume of autoradiogram bands from 8 to 16 mice for each experimental condition is shown in the bottom of each panel. Values in graphs are the means ± SEM. ^P < 0.05 compared with the corresponding value at time 0. EAAT3 −/− : glutamate transporter type 3 knockout.
