| Research Abstract |
The duct system of mouse submandibular gland has a pronounced sexual dimorphism, in which granular convoluted tubules (GCT) are developed preferentially in males, but its molecular mechanisms are unclear. The present study has revealed that JunD and CREB, which belong to the transcription factors functioning downstream of transmembrane receptors, disappear from the nuclei as a result of androgen-induced differentiation of GCT cells from striated duct cells. These results suggest that a special kind of cross-talk between the androgen receptor and other transcription factors is involved in the differentiation of the submandibular duct system.
