Cholera toxin and analogues of cyclic AMP stimulate the growth of cultured human mammary epithelial cells

J Taylor-Papadimitriou et al. J Cell Physiol. 1980 Mar.

Abstract

The growth of human epithelial cells is stimulated by cholera toxin and analogues of cyclic AMP, while the growth of breast derived fibroblasts is inhibited. These compounds have little effect on DNA synthesis in the absence of other mitogens but show a synergistic effect with serum and/or EGF. The results suggest that high intracellular levels of cyclic AMP in human mammary epithelial cells increase the growth response of the cell to mitogens.
