title: The deficiency of cyclic AMP responsive G1 controls in cultured malignant liver epithelial cells.
abstract: Normal rat liver epithelial cells in culture were blocked outside the S phase by dibutyryl cyclic AMP while malignant rat liver epithelial cells were slowed in S phase. It is suggested that this lack of normal response to a growth inhibitory factor by malignant cells may underly their relatively autonomous growth behavior.
