The effect of castration or administration of testosterone propionate on the subcellular distribution of androgen receptor in mouse submandibular gland was investigated. Within 10 h after castration of male mice, most of the androgen receptor in nuclei was significantly reduced, the androgen receptor in cytosol increased and the increased cytosol receptor retained for at least 40 h. A single injection of testosterone propionate to female mice resulted in the translocation of cytosol androgen receptor to the nuceli by 30 min. The nuclear receptor level remained for at least 24 h and the cytosol receptor was replenished by 24-72 h. These results reveal that the endocrine manipulations such as castration and testosterone injection cause the change in the subcellular distribution of androgen receptor from mouse submandibular gland in both sexes.
