The growth factors derived from the microenvironment create an environment conducive to tumor growth and survival. HGF deprivation using neutralizing antibody enhanced chemosensitivity in colorectal cancer cells (CRC). We determined secreted HGF in fibroblast conditioned medium (CM). Combination treatment of anti-HGF antibody and irinotecan (CPT-11) directly enhanced CPT-11 sensitivity in CRC. ...
BACKGROUND Hepatocyte growth factor (HGF) is known to be involved in the resolution of pulmonary inflammation and repair of acute lung injury. Legionella pneumonia is sometimes complicated by acute lung injury. Our study aimed to determine the role of serum HGF levels in Legionella pneumonia. METHODS Sera from patients with Legionella pneumonia (42 cases), other bacterial pneumonia (33 cases)...
Medulloblastomas are malignant brain tumors that arise by transformation of neural progenitor cells in the cerebellum in children. Treatment-related neurotoxicity has created a critical need to identify signaling molecules that can be targeted therapeutically to maximize tumor growth suppression and minimize collateral neurologic injury. In genetically engineered mice, activation of Sonic Hedge...
Hepatocyte growth factor (HGF) is a growth factor that protects alveolar epithelial cells from pulmonary fibrosis in various animal models. We compared in vitro HGF production by human lung fibroblasts from patients with idiopathic pulmonary fibrosis (IPF, n = 8) and from control subjects (n = 6). Basal HGF secretion by IPF fibroblasts was decreased by 50% when compared with control fibroblasts...
Hepatocyte growth factor (HGF) is a multifunctional protein implicated in tissue regeneration, wound healing, and angiogenesis. We measured serum HGF concentrations in 37 patients with peripheral arterial occlusive disease (PAOD). Among them, 36 patients underwent arteriography. Serum HGF concentrations were also measured in 40 control subjects who remained free of vascular, liver, kidney, or l...
OBJECTIVE Hepatocyte growth factor/scatter factor (HGF/SF) promotes vascular endothelial growth factor (VEGF) expression and induces angiogenesis in multiple pathological conditions. The present study was designed to delineate the HGF/SF and VEGF signaling cascades during angiogenesis by using PTK787, a selective VEGF receptor antagonist. METHODS AND RESULTS PTK787 produced a concentration-de...
Hepatocyte growth factor (HGF) is one of the adipocytokines. We evaluated whether serum levels of HGF are related to the metabolic syndrome. A total of 1474 subjects of a general population free of liver, kidney, and lung diseases received a health examination. We measured blood pressure, waist circumference, body mass index, fasting plasma glucose, lipid profiles, serum insulin, liver enzymes,...
Hepatocyte growth factor (HGF) promotes cell growth and motility and also increases neovascularization. Multiple myeloma (MM) cells produce HGF, and the plasma concentration of HGF is significantly elevated in patients with clinically active MM, suggesting that HGF might play a role in the pathogenesis of MM. NK4, an antagonist of HGF, is structurally homologous to angiostatin, and our previous...
Hepatocyte growth factor (HGF) is known to promote renal epithelial cell survival by dual mechanisms involving Bad phosphorylation and Bcl-xL induction. However, it remains elusive as to the relative contributions of these two events to HGF-mediated cytoprotection. Here we investigated the role and mechanism of HGF in protecting renal epithelial cells from death induced by oxidant stress both i...
The hepatocyte growth factor (HGF) receptor, encoded by the MET oncogene, is expressed in approximately 70% of human ovarian carcinomas and overexpressed in 30% of cases. Because HGF is known to protect cells from apoptosis, we investigated whether receptor expression modifies ovarian cancer cell response to chemotherapy. The apoptotic effect of the front-line chemotherapeutic drugs paclitaxel ...
