Astrogliosis in Psmc1fl/fl;CaMKIIα-Cre forebrain. (A) Representative horizontal brain sections immunostained with glial fibrillary acidic protein (GFAP). No significant differences were evident in control cortices; therefore the control image is representative of all ages. Insets show the region of cortex shown (LHS; oval) and a higher magnification image of the neuropathological finding (RHS; white box). Scale bar = 500 (LHS; cortex) and 200 (RHS; hippocampus) µm. Representative immunoblots and quantification of GFAP in control and Psmc1fl/fl;CaMKIIα-Cre cortices (B) and hippocampi (C). Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) was used as a loading control at each age for quantification; a representative GAPDH is shown. Images were cropped from those shown in Supplementary Figure 7. Mean ± SEM of n = 4 mice. *p < 0.05, **p < 0.01 and ***p < 0.001 by unpaired Students t-test.
