Microinjection of St-Ht31 peptide reduces PSD content of PKA and surface expression of GluR1. A, Microinjections of St-Ht31 reduced PSD content for PKAc. Data were normalized to LGN content. B, Peptide microinjections were made as in A, except tissue was prepared for biotinylation and Western blotting for GluR1. Data are shown as the ratio of the density of the GluR1 band between the two treatment groups (St-Ht31/St-Ht31P). Dashed line indicates a ratio of 1.0. *p < 0.05 comparing control with active peptide using a two-tailed Student's t test.
