STRING evaluation reveals protein interaction networks in heart phosphoproteome in NC/NS comparison group. Interactions of your identified phosphoproteins had been mapped by browsing the STRING (Search Tool for the Retrieval of Interacting Genes/Proteins) database version 9.0 with a self-assurance cutoff of 0.6. Inside the resulting protein association network, proteins are presented as nodes which are connected by lines whose thickness represents the confidence level (0.6.9). doi:10.1371/journal.pone.0100331.gphospho-lamin A in CRF animals (Figure 6a). Further, a considerable raise in desmin mRNA level was observed in high salt-fed CRF rats (Figure 6c), which corresponded with elevated phospho-lamin A expression. We then examined expression of phospho-phospholamban in left ventricular free of charge walls. SERCA/phospholamban complicated regulates cardiac muscle contractility by controlling Ca2+ transport in cariomyocytes. Phosphorylation of phospholamban increases SERCA expression [36]. Western analysis of left ventricular no cost walls revealed a substantial reduce in phosphor-phospholamban expression in CRF rats (Figure 6b). High salt intake resulted in a additional reduction of phosphorylated phospholamban in CRF rats (Figure 6b). Regularly, mRNA levels of its downstream gene SERCA had been thus decreased in NCPLOS One | plosone.organd HC groups (Figure 6d). Together, these data lend support to our proteomic evaluation.DiscussionPrevious studies have suggested substantial alterations of phosphorylated heart proteins in animal models which include spontaneously hypertensive rats [21,379], Dahl rats [40] and heart failure model [41] or cardiac cell line [42]. Protein phosphorylation plays a crucial role in regulation of cardiac function. It must be noted that we have been the very first to investigate the phosphorylated proteins of the heart too as characterize the variations induced by higher salt intake in the remnant kidney model.Salt-Induced Changes in Cardiac Phosphoproteome and CRFFigure 5. STRING analysis reveals protein interaction networks in heart phosphoproteome in HC/NC comparison group. Interactions of the identified phosphoproteins were mapped by looking the STRING database version 9.0 with a confidence cutoff of 0.six. Inside the resulting protein association network, proteins are presented as nodes which are connected by lines whose thickness represents the self-confidence level (0.six.9). doi:10.1371/journal.pone.0100331.gWe have identified 763 phosphorylated proteins and 1724 phosphopeptides by iTRAQ as well as LC-MS/MS. Here we’ve got demonstrated that quantitative iTRAQ-based LC MS/MS is really a robust p.
