In the paper "Impaired perfusion after myocardial infarction is due to reperfusion-induced
PKC-mediated myocardial damage" by Ikeno et al. [1], Dr. Daria Mochly-Rosen's group at Stanford University have demonstrated a novel molecular interventional strategy, targeted inhibition of the
isoform of protein kinase C (
PKC), to treat the post-ischemic no-reflow phenomenon in the myocardium using both mouse and pig models. This they achieved by either expressing a
PKC-specific translocation inhibitor protein fragment,
V1-1, only in cardiomyocytes in a transgenic crystalloid perfused mouse ex-vivo acute global myocardial ischemia (30 min)/reperfusion (120 min) model or through intra-coronary delivery of the TAT-conjugated synthetic peptide
V1-1 during the last minute of ischemia in a porcine in-vivo regional (LAD) myocardial ischemia
