Fig. 6. Expression of cell cycle regulators in control and STAT3-C-expressing cells. Cells were serum-starved for 24 h, and then they were exposed to medium alone (-), medium containing EGF (30 ng/ml), or medium containing TGF-{alpha} (30 ng/ml) for 2 h. Extracts were then prepared and immunoblotted for cell cycle regulators as indicated.
