| abstractText | Alanine and arginine rich domain containing protein (Aard) is specifically expressed in Sertoli cells (SCs) of mouse testis and the expression increases in an agedependent manner. A number of previous studies have indicated that androgen and androgen receptor (AR) signaling pathways are particularly important for spermatogenesis in mouse SCs, however, the association between Aard and AR remain to be elucidated. The present study identified Aard as a gene that is directly regulated by AR in mouse SCs, which is important in spermatogenesis. The expression of AARD was significantly downregulated in the testes of Sertoli cellselective AR knockout mice compared with wildtype mice as analyzed by western blotting and immunofluorescence analyses. Quantitative polymerase chain reaction and western blotting indicated that AARD was predominantly expressed in adult mouse testis and its expression was increased in an age-dependent manner. In addition, AARD expression was upregulated by testosterone in primary SCs in vitro, which was confirmed by bioinformatics analysis and a dualluciferase reporter assay. Finally, chromatin immunoprecipitation and electrophoretic mobility shift assays indicated that the ligandbound AR activated Aard transcription via directly binding to the androgenresponsive element of the Aard promoter. To the best of our knowledge, the present study is the first to document that Aard is directly regulated by AR in mouse Sertoli cells. |
