The Cbl protooncogene product has emerged as a negative regulator of receptor and nonreceptor tyrosine kinases. We recently demonstrated that oncogenic Cbl mutants upregulate the endogenous tyrosine kinase signaling machinery when expressed in the NIH 3T3 cells, and identified the platelet-derived growth factor receptor-alpha (PDGFRalpha) as one of the tyrosine kinases targeted by these oncogen...
preparations of platelet concentrates (pcs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (pmps) with high coagulant activity that may change platelet efficacy and safety issues. high shear stress could cause shedding of pmps from the platelet plasma membrane, platelet aggregation, and activation of the co...
OBJECTIVES Fibroblast migration is an initiating step in fibroproliferation; its involvement during acute lung injury and acute respiratory distress syndrome remains poorly understood. The aims of this study were: 1) to determine whether bronchoalveolar lavage fluids from patients with acute lung injury/acute respiratory distress syndrome modulate lung fibroblast migration; 2) to assess lung fi...
OBJECTIVE To assess whether an erythematous eruption in the vicinity of or distant from a melanoma lesion might be related to the vascular endothelial growth factor, the platelet-derived endothelial cell growth factor, or both. METHODS Biopsy specimens from 13 patients with primary melanoma, 6 of whom had erythematous eruptions and 7 who did not, were studied by immunohistochemistry for the e...
The growth of neointima and neointimal smooth muscle cells in baboon polytetrafluoroethylene grafts is regulated by blood flow. Because neointimal smooth muscle cells express both platelet-derived growth factor receptor-alpha and -beta (PDGFR-alpha and -beta), we designed this study to test the hypothesis that inhibiting either PDGFR-alpha or PDGFR-beta with a specific mouse/human chimeric anti...
