Abstract:

 The objectives of this study were to evaluate the expression of Androgen receptors (AR) in various tissues and the cellular localization of gonad of the male sheep lambs. In this experiment, mRNA expression was detected by real-time fluorescent quantitative PCR. Cellular localization of AR in testis and epididymidis were examined by immunohistochemistry. Qualitative investigation of AR protein was expressed by Western blotting. The result showed that: (1) Sheep AR mRNA was expressed in all the tissues, and abundantly expressed in testis and heart. (2) Weak positive signals were detected in pseudo stratified ciliated columnar epithelium and interstitial tissue of EpH, EpB and EpT. Strong positive signals were detected in interstitial tissue, spermatogenous cells and myoid cells of sheep testis. Sheep AR was widely expressed in all the tissues. AR plays an important role in gonadal developing and sperm maturation processing and heart protecting, the mechanisms need further research.
