In milk from substrains of mice with varying incidences of developing mammary tumor, we have isolated a specific mitogenic activity, which is unique in that it identifies mice with mammary tumor and predicts those mice that will eventually develop mammary tumor. None of the milk samples from control mice, who never developed mammary tumor, contained this specific predictive mitogenic activity. Chemical characterization has shown this specific mitogenic activity to be acid- and heat-stable and resistant to reducing agents. Partial purification, by ion-exchange, high-performance liquid chromatography size-exclusion, and isoelectrofocusing techniques, of this specific mitogenic activity from milk of mice that had or eventually developed mammary tumor identifies several peptide growth factor components in a 6-10 kDa molecular weight range. Of known growth factors, radioassay techniques identify an insulin-like growth factor-1-like peptide as a major component. Small amounts of platelet-derived growth factor and transforming growth factor-beta activities also were present. Our results suggest that a subset of growth factors that are diagnostic of the presence of murine mammary tumor and predictive of eventual tumor development may be early indicators of the transition of a competent cell to a progressively malignant state. Similar studies of a secreted body fluid from women at risk for breast cancer may lead to the identification of a specific biologic tumor marker for breast cancer.
