Localization and expression of TR3 orphan receptor protein and its mRNA in rat

The cellular localization and specific expression of TR3 mRNA in rat testis were investigated by the method of immuno- histochemistry andin situ hybridization. It was demonstrated that orphan receptor TR3 was expressed in a significant amount in rat testis and TR3 protein and mRNA were specifically localized in germ cells, suggesting that TR3 may have an important function in regulating rat germ cell development.
