    ..In conclusion, the results suggest that a CERA prevents CKD-induced susceptibility of the myocardium to ischemia/reperfusion injury by restoration of Akt-mediated signaling possibly via normalized malate-aspartate shuttle flux. ..

  8. Ohno K, Kuno A, Murase H, Muratsubaki S, Miki T, Tanno M, et al. Diabetes increases the susceptibility to acute kidney injury after myocardial infarction through augmented activation of renal toll-like receptors in rats. Am J Physiol Heart Circ Physiol. 2017;:ajpheart.00205.2017 pubmed publisher
    ..The results suggest that DM increases susceptibility to AKI after acute MI by augmented activation of renal TLRs and that TLR1/TLR2-mediated signaling mediates KIM-1 upregulation after MI. ..
  9. Tanno M, Kuno A, Ishikawa S, Miki T, Kouzu H, Yano T, et al. Translocation of glycogen synthase kinase-3? (GSK-3?), a trigger of permeability transition, is kinase activity-dependent and mediated by interaction with voltage-dependent anion channel 2 (VDAC2). J Biol Chem. 2014;289:29285-96 pubmed publisher
    ..These results demonstrate that GSK-3? translocates from the cytosol to mitochondria in a kinase activity- and VDAC2-dependent manner in which an N-terminal domain of GSK-3? may function as a mitochondrial targeting sequence. ..
  10. Murase H, Kuno A, Miki T, Tanno M, Yano T, Kouzu H, et al. Inhibition of DPP-4 reduces acute mortality after myocardial infarction with restoration of autophagic response in type 2 diabetic rats. Cardiovasc Diabetol. 2015;14:103 pubmed publisher
    ..The results indicate that vildagliptin reduces T2DM-induced increase in post-MI acute mortality possibly by restoring the autophagic response through attenuation of Bcl-2-Beclin-1 interaction. ..
