EGF-induced phenotype changes of A431 cells is PTP dependent. A431 cells were treated with EGF (100 ng/ml) or pervanadate (50 μM) or pretreated with pervanadate (50 μM) for 30 min before EGF treatment. The tyrosine phosphorylation levels of FAK (A) and cell morphology (B) were examined as described in the legend to Fig. ​Fig.11.
