Understanding the origins and roles of cardiac progenitor cells is important for elucidating the pathogenesis of congenital and acquired heart diseases. Moreover, manipulation of cardiac myocyte progenitors has potential for cell-based repair strategies for various myocardial disorders. Here we report the identification in mouse of a previously unknown(More)
Compartmentation and dynamics of cAMP and PKA signaling are important determinants of specificity among cAMP's myriad cellular roles. Both cardiac inotropy and the progression of heart disease are affected by spatiotemporal variations in cAMP/PKA signaling, yet the dynamic patterns of PKA-mediated phosphorylation that influence differential responses to(More)
BACKGROUND Metabolites released by the gut microbiota may influence host metabolism and immunity. We have tested the hypothesis that inulin-type fructans (ITF), by promoting microbial production of short-chain fatty acids (SCFA), influence cancer cell proliferation outside the gut. METHODS Mice transplanted with Bcr-Abl-transfected BaF3 cells, received(More)
BACKGROUND Metastatic tumour cells are characterised by acquisition of migratory and invasive properties; properties shared by cells, which have undergone epithelial-to-mesenchymal transition (EMT). Disabled-2 (Dab2) is a putative tumour suppressor whose expression has been shown to be downregulated in various cancer types including breast cancer; however,(More)
BACKGROUND PINCH proteins are 5 LIM domain-only adaptor proteins that function as key components of the integrin signaling pathway and play crucial roles in multiple cellular processes. Two PINCH proteins, PINCH1 and PINCH2, have been described in mammals and share high homology. Both PINCH1 and PINCH2 are ubiquitously expressed in most tissues and organs,(More)
Cytostasis and cytotoxicity as well as survival and growth of EMT6 cells following exposure to tumoricidal macrophages have been examined using multiparameter flow cytometry. Macrophages were resolved from tumor cells, and the number of surviving EMT6 cells at different interaction times was determined by adding, to each cell suspension, fluorescent latex(More)
