ABSTRACT
Objective To analyze the changes of energy metabolism-related proteins(enzymes) and transformation of energy metabolism in transplanted heart.Methods The hearts transplanted from Lewis to Wister rats as allografts and from Lewis to Lewis rats as isografts were used to estab- lish Ono model.The changes in proteins were observed by using proteomics technique and compared between allografts and isografts in the left ventricular myocardial tissues 2 and 8 weeks after heart transplantation.Peptide mass fingerprint map was obtained by using matrix-assisted laser desorption/ ionization time of flight mass spectrometry(MALDI-TOF-MS)and the matched proteins achieved by using Matrix Science software.Results Eighty proteins(enzymes)of total 65 differential proteins that regulated energy metabolism were identified in allografted hearts,which correlated to the Krebs cycle and electron transport system involving glycometabolism,fatty acid and branched-chain amino acids oxidation.Conclusion The energy metabolism in allografts heart was transformedmitochondria function was decreased in Krebs cycle but enhanced in electron transport system and outer mitoehon- drial membrane permeability to ATP,accelerated in glycolysis and fatty acid oxidation,however, branched-chain amino acids oxidation were suppressed.
