Fig. 9. Reactive oxygen species are required for reactivation of p44ERK activity
during recovery. (A) Western blot analysis (top) and quantification (bottom)
of basal p44ERK activity after 1 h treatment of RTHDF cells with 100 nmol
l1 DPI (N=3, *P<0.05). (B) Western blot
analysis (top) and quantification (bottom) of phospho-ERK1-specific bands
after 1 h treatment of RTHDF cells with 100 nmol l1 DPI
prior to chemical anoxia/recovery (A/R) (N=3,
*P<0.05).
