A, representative in situ hybridization images of melanocortin 2 receptor (MC2-R) mRNA expression in the adrenal. Relative optical density (ROD) of steroidogenic factor (SF)-1 mRNA (B), steroidogenic acute regulatory protein (StAR) mRNA (C), MC2-R mRNA (D), CYP11A1 mRNA (E) and CYP17 mRNA (F). Animal numbers are indicated within bars. **P < 0.01, compared to control.
