The recent development of hyperpolarized (13)C magnetic resonance spectroscopic imaging provides a novel method for in vivo metabolic imaging with potential applications for detection of cancer and response to treatment. Chemotherapy-induced apoptosis was shown to decrease the flux of hyperpolarized (13)C label from pyruvate to lactate due to depletion of NADH, the coenzyme of lactate dehydroge...
Transforming growth factor-β (TGFβ) is a key mediator of fibrogenesis. TGFβ is overexpressed and activated in fibrotic diseases, regulates fibroblast differentiation into myofibroblasts and induces extracellular matrix deposition. Platelet-derived growth factor (PDGF) is also a regulator of fibrogenesis. Some studies showed a link between TGFβ and PDGF in certain fibrotic diseases. TGFβ induces...
BACKGROUND Malignant pleural mesothelioma (MPM) is an asbestos related tumour difficult to detect early and treat effectively. Asbestos causes genetic modifications and cell signalling events that favour the resistance of MPM to apoptosis and chemotherapy. Only a small number of patients, approximately 10%, survive more than 3 years. The aim of our study was to assess possible differences withi...
Multiple in vivo phosphorylated tyrosine phosphatase SHP-2 engages binding to Grb2 via tyrosine 584.
SHP-2 (also named PTP1D, syp, or SH-PTP2) has been identified as a phosphotyrosine phosphatase comprising two src-homology-2 (SH2) domains. Upon growth factor stimulation, SHP-2 becomes tyrosine phosphorylated, thereby increasing its catalytic activity. Here, we identified SHP-2 to be phosphorylated on multiple tyrosine residues in response to different stimuli and unmasked the carboxyl-termina...
Background: In this study, we examined a new two step induction protocol for improving the differentiation of human umbilical cord blood-derived mesenchymal stem cells into neural progenitor cells. Materials and Methods: Human umbilical cord blood-derived mesenchymal stem cells were first cultured in Dulbecco’s modified eagle medium supplemented with 10% fetal bovine serum in a humidified incu...
Using human MSCs (mesenchymal stem cells) lacking VEGF (vascular endothelial growth factor) receptors, we show that the pro-angiogenic receptor neuropilin-1 associates with phosphorylated PDGFRs [PDGF (platelet-derived growth factor) receptors], thereby regulating cell signalling, migration, proliferation and network assembly. Neuropilin-1 co-immunoprecipitated and co-localized with phosphoryla...
