In this study, we demonstrate the use of proteomics to detect regional differences in protein levels between the reperfused ischemic zone (IZ) and the nonischemic zone (NIZ) of dog hearts which were subjected to in vivo ischemia-reperfusion injury. Using the two-dimensional gel electrophoresis (2-DE) technique, we identified five proteins that were differentially expressed in the IZ versus NIZ: (1) the alpha subunit of ATP synthase isoform precursor was decreased 1.71-fold; (2) creatine kinase M chain was decreased 1.72-fold; (3) NAD+-isocitrate dehydrogenase, a subunit was increased 8.34-fold; (4) ATP synthase D chain, mitochondrial was increased 3.02-fold; (5) ventricular myosin light chain-1 was decreased 2.02-fold. Additionally, we found that the level of actin was decreased 2.6-times in the IZ compared to the NIZ on Western blot analysis but was unchanged on 2-DE.
