PURPOSE Hepatocyte growth factor/scatter factor (HGF/SF) possesses mitogenic, motogenic, and morphogenic properties and has recently been implicated in various retinal diseases. The role of HGF/SF in proliferative vitreoretinal disease was investigated. METHODS Sections of epiretinal membranes were stained immunohistochemically for cytokeratins, to identify HRPE cells, and for HGF/SF receptor...
Hepatocyte growth factor (HGF) and Met/HGF receptor play roles in dynamic growth and morphogenesis during development and regeneration of organs, including the kidney. In the kidney, HGF targets different types of cells, while its biological actions depend on a target cell type. During the earlier stages of chronic renal failure, renal HGF expression increased, but in later stages HGF expressio...
OBJECTIVE Lipopolysaccharide (LPS) triggers sepsis and systemic inflammatory response syndrome, which results in multiple organ failure. Our recent reports demonstrated that hepatocyte growth factor (HGF) attenuated angiotensin II-induced oxidative stress via epithelial growth factor receptor (EGFR) degradation in vascular smooth muscle cells. Here, we examined whether HGF can protect against s...
Mesenchymal-epithelial tissue interactions are important for development of various organs, and in many cases, soluble signaling molecules may be involved in this interaction. Hepatocyte growth factor (HGF) is a mesenchyme-derived factor which has mitogenic, motogenic and morphogenic activities on various types of epithelial cells and is considered to be a possible mediator of epithelial-mesenc...
Increased expression of hepatocyte growth factor (HGF) has been shown to be associated with aggressiveness in several types of cancer. Shorter variants of deoxyadenosine tract element (DATE) located in the HGF promoter region have been reported to enhance the expression of HGF. In this study, we investigated the role of HGF DATE variants in bladder cancer risk, HGF expression and clinicopatholo...
Hepatocyte growth factor (HGF) promotes lung epithelial repair after injury. Because prior studies established that human neutrophil proteases inactivate HGF in vitro, we predicted that HGF levels decrease in lungs infiltrated with neutrophils and that injury is less severe in lungs lacking HGF-inactivating proteases. After establishing that mouse neutrophil elastase cleaves mouse HGF in vitro,...
Hepatocyte growth factor/scatter factor (HGF/SF) and its receptor, c-Met, have been implicated in the growth and progression of a variety of solid human tumors. Thus, inhibiting HGF/SF:c-Met signaling may provide a novel therapeutic approach for treating human tumors. We have generated and characterized fully human monoclonal antibodies that bind to and neutralize human HGF/SF. In this study, w...
OBJECTIVE Cardiotrophic growth factors with anti-cell death actions on cardiac myocytes have gained attention for treatment of patients with myocardial infarction. Hepatocyte growth factor (HGF) plays a role in tissue repair and protection from injuries, however, the physiological role of HGF in the myocardium has not been well defined. We asked if HGF would afford to the infarcted myocardium. ...
Serum hepatocyte growth factor (HGF) is rapidly increased in patients suffering from various tissue injuries including arterial occlusive diseases. However, the cellular sources of the HGF increase remain largely unknown. In the present study, we showed that bioactive mature HGF is constitutively present on the surface of granulocytes in human peripheral blood. Exogenously added 125I-labeled io...
Multiple myeloma (MM) is a common hematologic neoplasm consisting of malignant plasma cells, which expand in the bone marrow. A potential key signal in the evolution of MM is hepatocyte growth factor (HGF), which acts as a potent paracrine and/or autocrine growth factor and survival factor for MM cells. Proteolytic conversion of HGF into its active form is a critical limiting step in HGF/MET si...
