Steroidogenic enzymes, local testosterone concentrations, and androgen receptors (AR) in the mesocorticolimbic system of adult male rats. (A) Levels of steroidogenic enzyme mRNA are based on probe-based quantitative polymerase chain reaction (qPCR) assays (36). (B) Local testosterone (T) concentrations are based on Brain T: Blood T ratios in intact adult male rats [fed ad libitum or calorie restricted (36)]. (C) Levels of AR mRNA are based on probe-based qPCR assays (36), and levels of AR protein are based on immunohistochemistry (33). Levels of AR mRNA and AR protein are not shown relative to one another.
