Invasiveness and metastasis of NIH 3T3 cells induced by Met-hepatocyte growth factor/scatter factor autocrine stimulation.
The met protooncogene product, Met, is the tyrosine kinase growth factor receptor for hepatocyte growth factor/scatter factor (HGF/SF). NIH 3T3 cells express HGF/SF endogenously and become tumorigenic in nude mice via an autocrine mechanism when murine Met is expressed ectopically (Metmu cells) or when human Met and human HGF/SF are coexpressed (HMH cells). Here, we show that Metmu and HMH cell...
متن کاملVascular endothelial growth factor (VEGF) is an autocrine growth factor for VEGF receptor-positive human tumors.
Angiogenesis is required for the progression of tumors from a benign to a malignant phenotype and for metastasis. Malignant tumor cells secrete factors such as vascular endothelial growth factor (VEGF), which bind to their cognate receptors on endothelial cells to induce angiogenesis. Here it is shown that several tumor types express VEGF receptors (VEGFRs) and that inhibition of VEGF (VEGF ant...
متن کاملNovel xenograft model expressing human hepatocyte growth factor shows ligand-dependent growth of c-Met-expressing tumors.
c-Met, a receptor tyrosine kinase responsible for cellular migration, invasion, and proliferation, is overexpressed in human cancers. Although ligand-independent c-Met activation has been described, the majority of tumors are ligand dependent and rely on binding of hepatocyte growth factor (HGF) for receptor activation. Both receptor and ligand are attractive therapeutic targets; however, precl...
متن کاملEstablishment of human hair follicle mesenchymal stem cells with overexpressed human hepatocyte growth factor
Objective(s): Chronic liver disease has become a major health problem that causes serious damage to human health. Since the existing treatment effect was not ideal, we need to seek new treatment methods. Materials and Methods: We utilized the gene recombination technology to obtain the human hair mesenchymal stem cells which overexpression of human hepatocyte growth factor (hHGF). Furthermore, ...
متن کاملMet and hepatocyte growth factor/scatter factor expression in human gliomas.
Using double immunofluorescence staining and quantitative confocal laser scan microscopy, we show that the intensity of hepatocyte growth factor/scatter factor (HGF/SF) and Met staining in human primary brain tumors increases with the grade of malignancy and is prevalent in both the infiltrating tumor cells and endothelial hyperplastic areas. HGF/SF and Met also are expressed in vitro in gliobl...
