Androgens alter expression of synaptic proteins in the SCN. Bar graphs quantifying Western blottings of SCN cell lysates from INT, GDX, and GDX+DHT mice for synaptic proteins synaptophysin (A) and PSD95 (B). Synaptophysin levels were decreased after GDX, with DHT treatment blocking the effect. PSD95 levels were affected by hormone treatment, although there was no statistically significant effect of GDX compared with INT. However, GDX+DHT mice had increased synaptophysin levels compared with GDX; *P < 0.05. AU, Arbitrary units.
