Data illustrate for each sex mean normalized GABAergic neuron α1AR [Panel A], α2AR [Panel B], and β1AR [Panel C] protein O.D. measures ± S.E.M. for groups of male and female rats treated as follows: V/V (white bars; n=6 males, n=6 females), V/INS (10.0 U/kg bw, sc; solid gray bars; n=6 males, n=6 females), MPP/INS (diagonalstriped gray bars; n=6 males, n=6 females), and PHTPP/INS (cross-hatched gray bars; n=6 males, n=6 females). Data were analyzed by two-way ANOVA for sex versus treatment. *p<0.05; **p<0.01; ***p<0.001.
