title: Epidermal growth factor, insulin-like growth factor-1 and basic fibroblast growth factor modulate the cytostatic effect of tumour necrosis factor-alpha on the breast cancer cell line, T47D.
abstract: The effect of epidermal growth factor (EGF), basic fibroblast growth factor (bFGF) and insulin-like growth factor-1 (IGF-1) on the cytostatic activity of tumour necrosis factor-alpha (TNF-alpha) was studied on the breast cancer cell line, T47D. TNF-alpha completely blocked the potent growth-promoting activity of all three factors on T47D cells. EGF, bFGF and IGF-1 partially antagonized the inhibition of cell growth and thymidine incorporation induced by TNF-alpha. These data suggest that the growth of these breast cancer cells is regulated, in part, by the antagonistic interaction between the cytostatic effect of TNF-alpha and the growth-promoting activity of factors such as EGF, IGF-1 and bFGF.
