Identification of a pituitary factor responsible for enhancement of plasminogen activator activity in breast tumor cells.

Sheep pituitary glands contain a protein that stimulates plasminogen activator (PA) activity 3- to 20-fold in serum-free cultures of T47D, MTW9/PL, and SC115 breast tumor cells. This protein was found to be similar to basic fibroblast growth factor ( bFGF) in size, cationic nature, and affinity for heparin. Purified human placental bFGF, a homologue of human and bovine pituitary bFGF, was effective in stimulating mammary tumor cell PA at a concentration of 1 ng/ml. Antibodies to placental bFGF blocked the PA stimulatory activity of sheep pituitary extracts. Because of these properties, the active protein in sheep pituitary glands was identified as bFGF. This represents another function of bFGF, indicating that its spectrum of target cells is wider than previously thought. Because of previously established correlations between PA production in vitro and tumor growth in vivo, we suggest that bFGF may contribute to the growth of breast carcinomas in vivo. Other types of carcinomas may also be affected by bFGF.[1]
