Alterations of serine/threonine phosphorylation of the cardiac proteome are a hallmark of heart failure. However, the contribution of tyrosine phosphorylation (pTyr) to the pathogenesis of cardiac hypertrophy remains unclear. We use global mapping to discover and quantify site-specific pTyr in two cardiac hypertrophic mouse models, i.e., cardiac overexpression of ErbB2 (TgErbB2) and α myosin heavy chain R403Q (R403Q-αMyHC Tg), compared to control hearts. From this, there are significant phosphoproteomic alterations in TgErbB2 mice in right ventricular cardiomyopathy, hypertrophic cardiomyopathy (HCM), and dilated cardiomyopathy (DCM) pathways. On the other hand, R403Q-αMyHC Tg mice indicated that the EGFR1 pathway is central for …

Pancreatic ductal adenocarcinoma (PDAC) is a devastating malignancy, especially as there are no current reliable methods of screening. Recently literature reports a significant relationship with pancreatic ductal adenocarcinoma and diabetes mellitus (DM). The pathologic molecular mechanism is not completely understood but it may hold insights into the development of novel screening and treatment options. In our study we compiled a list of 74 proteins involved in the PDAC and DM pathway, with 47 showing increased expression levels and 11 with decreased expression levels. These proteins are currently undergoing further computational analysis to identify their pathway interactions.
