Decreased GABAA receptor δ subunit expression in the striatum in pregnant animals. A, Representative bright-field and spectrum color-transformed images of the striatum from wild-type virgin, pregnant, and Gabrd−/− virgin mice stained with an antibody specific for the GABAAR δ subunit. B, Optical density measurements show a significant decrease in GABAAR δ subunit in wild-type pregnant mice compared with virgin mice. The lack of staining in Gabrd−/− virgin mice confirm the specificity of the antibody. *p < 0.05 using the Student's t test compared with virgin wild type. a.u., Arbitrary units.
