Androgen receptor is necessary for the proliferation of androgen-dependent tumors including human prostatic cancer and murine androgen-sensitive tumors. However, androgen-independent tumor containing functional androgen receptor was observed in CS 2 cells, which is a subline of androgen-dependent mouse tumor (SC 115). CS 2 showed a new expression of hst-1, the product of which is a family of FGF. CS 2 secreted a growth factor which promotes growth of CS 2 and original SC 115 in an autocrine and paracrine manner. The role of oncogene(s) and suppressor gene(s) on the progression of the tumor is discussed.
