title: Lysosomal inhibitors stimulate resting NIH 3T3 cells to proliferate.
abstract: Lysosomal inhibitors (amino acid methyl esters) and platelet-derived growth factor stimulate resting NIH 3T3 cells to enter the S period. Incubation of cells in medium containing lysosomal inhibitors causes an increase in protein accumulation and does not disrupt lysosomes. The results indicate that proliferative homeostasis depends partially on the metabolic status of the cell and that catabolic processes activated in resting cells negatively influence prereplicative reactions.
