Relative gene expression (median) in animal facility reared rats. Between-group comparisons indicate an effect of voluntary ethanol drinking on (C) Crh in the hypothalamus (U = 20; p = 0.043) and (A) Crhr1 (U = 17; p = 0.012) in the pituitary and an effect of single housing on (A) Crhr1 (U = 14; p = 0.036) and (B) Pomc (U = 14; p = 0.036) in the pituitary. AU, arbitrary units; Crh, corticotropin releasing hormone; Crhr1, corticotropin releasing hormone receptor 1; E, ethanol drinking; g, group housed; Pomc, proopiomelanocortin; s, single housed; W, water drinking.#p ≤ 0.05: effect of single housing; p ≤ 0.05: effect of ethanol.
