Expression of Homer1a protein in cingulate cortex. (A) Western blot of samples obtained from the WT, WT/FS, 3xTg (Tg), and Tg/FS groups. (B) Quantification of Homer1a protein expression. The density of the thicker Homer1a band at 30 kD was first standardized relative to β-actin, then averaged (N = 3), and finally expressed relative to the corresponding no-FS control group (WT or Tg). *, P < 0.05.
