Fig. 9. (A) Immunoblots of phosphorylated JNK (phospho-JNK) were similar to those for p38 MAPK (Fig. 5) but were normalized to the control values to remove a tendency for pJNK to increase with time. (B) There was a significant rise in pJNK in both hyper- (bottom) and hypotonic (top) shock at 5 min (^*P<0.05, t-test, N=3) and with hypertonic shock at 30 min (^*P<0.05), compared to the isotonic controls at the same time.
