title: Failure of breast cancer cells in long-term culture to aromatize androstenedione.
abstract: The ability of breast cancer cells in long-term tissue culture to aromatize androstenedione to estrone and estradiol was examined. (3H) androstenedione (1.1 x 10(-7)M) was incubated with 9 cell lines of human breast cancer and one line derived from a dimethylbenz(a)anthracene induced rat mammary tumor. No conversion to estrone or estradiol was detected. The findings are discussed in light of previous studies showing aromatization of androgens in breast cancer tissues.
