Fig. 4. Activation of p44ERK during recovery is MEK dependent. RTHDF cells were
challenged with chemical anoxia (A) and recovery (R) in the absence and
presence of 10 µmol l1 of the MEK1/2 inhibitor PD98059 in
the recovery medium. A representative western blot and quantification of band
intensity is shown, demonstrating the inhibitory effect of 10 µmol
l1 PD98059 (N=3, *P<0.05).
