As in bovine DCM, expression of the enzyme UCH was more than 8-fold elevated at the protein level andmore than 5-fold elevated at the mRNA level in human DCM. Moreover, this increased expression of UCH was shown by immunocytochemistry to be associated11.8 Summarywith the myocytes which do not exhibit detectable staining in control hearts. Overall protein ubiquitination was increased 5-fold in DCM relative to control heartsand using a selective affinity purification method we were able to demonstrate enhanced ubiquitination of a number of distinct proteins in DCM hearts. We haveidentified a number of these proteins by mass spectrometry.
Interestingly many ofthese proteins were the same proteins that we have previously found to be present at reduced abundance in DCM hearts [53]. This new evidence strengthensour hypothesis that inappropriate ubiquitin conjugation leads to proteolysis anddepletion of certain proteins in the DCM heart and may contribute to loss of normal cellular function in the diseased heart.11.7.4Proteomic Characterization of Cardiac Antigens in Heart Disease and TransplantationProteomics can be utilized to identify cardiac-specific antigens that elicit antibodyresponses in heart disease and following cardiac transplantation. This approachmakes use of Western blot transfers of 2DE separations of cardiac proteins. Theseare probed with patient serum samples and developed using appropriately conjugated anti-human immunoglobulins.
This strategy has revealed several cardiacantigens that are reactive with autoantibodies in DCM [70, 71] and myocarditis[72]. Cardiac antigens that are associated with antibody responses following cardiac transplantation have also been characterized and may be involved in acute [73]and chronic [74] rejection.11.8SummaryThe use of proteomics in cardiovascular research has enabled the identificationand characterization of differential protein expression in heart disease. By complementing genomic-based approaches, new insights into complex cellular processeswill improve our understanding of cardiac dysfunction. Proteomics should allowan understanding of disease at the molecular level and provide the means foridentifying novel diagnostic disease markers.
This in turn will accelerate the development of new therapeutic approaches.18919011 Proteomics, a Step Beyond Genomics11.9References1234567891011O’Farrell, P. H. High resolution two-dimensional electrophoresis of proteins. J.Biol. Chem. 1975, 250, 4007–4021.Anderson, N.
