title: Androgen metabolism in relation to growth stimulation by a uterine cell line.
abstract: The metabolism of radioactive testosterone, 5alpha-dihydrotestosterone, 4-androstene-3beta,17beta-diol or 4-androstene-3alpha,17beta-diol by the human cell line NHIK 3025, derived from a carcinoma of the uterine cervix, was studied. The cells were grown in Eagle's minimal essential medium (MEM) with a steriod concentration of 10-(7) M for 4 days. Androgen metabolism by this cell line is essentially the same as for other androgen-responsive cells. The most interesting testosterone metabolite in this system is 4-androstene-3beta,17beta-diol, and the separation of this compound from 4-androstene-3alpha,17beta-diol and the two corresponding 5alpha-reduced diols is described. Since 4-androsterone-3beta,17beta-diol is a more potent growth factor for these cells than testosterone, the small conversion of testosterone to 4-androstene-3beta, 17beta-diol observed could be responsible for the growth stimulation by testosterone.
