Abstract
The androgen receptor (AR) is a ligand-dependent transcription factor involved in the regulation of many different physiological processes. Dysfunction of AR causes diverse clinical conditions, such as testicular feminization mutation (Tfm) syndrome and prostate cancer. However, the molecular basis of the AR in these disorders largely remains unknown, as a result of a lack of genetic models. Using conditional targeting technique with Cre-loxP system, we successfully generated null AR mutant (ARKO) mice. The ARKO males grew healthily, but they showed typical Tfm abnormalities. The ARKO males exhibited late onset of obesity with impaired bone metabolism and sexual behaviors. No overt abnormality was found in female ARKO mice, but a premature ovarian failurelike phenotype was found with impaired folliculogenesis. Thus, andorogen/AR system supports normal reproduction as well as normal female reproduction.
