mRNA expression of the GABA
receptor α1, β2 and γ2 subunits in the spinal cord of PRIP-1-/- mice and wild-type mice. (A) Representative film autoradiograms showing the mRNA expression of GABAA receptor α1, β2 and γ2 subunits. (B) Semiquantitative analysis of GABAA receptor α1, β2, and γ2 subunit mRNA expression in the dorsal horn (DH), intermediate gray matter (IG) and ventral horn (VH) of the spinal cord in PRIP-1 -/-mice (black) and wild-type mice (white). Each value represents the mean and S.E.M. (*P < 0.05 , **P < 0.01 vs. wild-type, n = 3).
