Mammalian cell size is controlled by mTOR and its downstream targets S6K1 and 4EBP1/eIF4E.


The coordinated action of cell cycle progression and cell growth (an increase in cell size and cell mass) is critical for sustained cellular proliferation, yet the biochemical signals that control cell growth are poorly defined, particularly in mammalian systems. We find that cell growth and cell cycle progression are separable processes in mammalian cells… (More)
