| Research Abstract |
Progesterone (Pg) is intimately involved in the development of the mammary gland. Further, it is believed that Pg plays a role in breast cancer progression. However, little is known regarding its role in SGTs. In this study, we used ACCM, a human adenoid cystic carcinoma cell line established from the salivary gland, in order to clarify the role of the progesterone receptor (PR) on cell proliferation. No effect of Pg on cell proliferation was observed in the PR-deficient aggressive ACCM cells. However, after introducing PR into the ACCM cells, Pg markedly inhibited the proliferative activity of the cells. This inhibitory effect on cell proliferation was accompanied by p21 upregulation and Id1, c-myc downregulation. Moreover, Pg-treated PR transfectants showed significant morphological change. Our results suggested that PR reintroduction therapy might be a viable method of inhibiting human SGT progression.
