Fig. 1. PKN is activated in hearts subjected to I/R.
Effects of I/R on PKN Thr774 phosphorylation. (A) Time course of PKN Thr774 phosphorylation. (B) The level of PKN Thr774 phosphorylation was determined by densitometric analysis. The mean total PKN/actin or phosphorylated PKN/total PKN in sham operated mouse hearts was set as 1 (dotted line). n=3–4. * p<0.05 vs. sham
