Hepatocyte growth factor (HGF) regulates many cellular functions acting through c-Met, its specific tyrosine kinase receptor. We previously reported that in prepuberal rats HGF is secreted by the peritubular myoid cells during the entire postnatal testicular development and by the Sertoli cells only at puberty. We have also demonstrated that germ cells at different stages of development express...
The protein hepatocyte growth factor (HGF) and its receptor c-Met are produced in response to tissue injury and are functional in tissue repair mechanisms. Their favorable effects in the heart and vasculature include anti-inflammatory, antifibrotic, and proangiogenic actions. Because HGF is released in response to endothelial injury, higher levels of circulating HGF are associated with hyperten...
The effects of hepatocyte growth factor (HGF) on barrier functions were investigated by a blood-brain barrier (BBB) in vitro model comprising a primary culture of rat brain capillary endothelial cells (RBEC). In order to examine the response of the peripheral endothelial cells to HGF, human umbilical vascular endothelial cells (HUVEC) and human dermal microvascular endothelial cells (HMVEC) wer...
Many studies have suggested a role for the hepatocyte growth factor (HGF)/c-Met pathway in tumorigenesis. Some actions of HGF are believed to be mediated by cyclooxygenase-2 (COX-2), resulting in the production of prostaglandin E2 (PGE(2)). We examined four c-Met-positive non-small-cell lung cancer (NSCLC) cell lines for effects of HGF on COX-2. HGF increased COX-2 protein expression 3-fold ove...
Increased numbers of tumor-infiltrating neutrophils are linked to poorer outcome in patients with adenocarcinoma of the bronchioloalveolar carcinoma (BAC) subtype. Hepatocyte growth factor (HGF) is a pleiotropic cytokine operating through activation of the proto-oncogene c-met and is a factor of poor prognosis in various cancers. Reports that neutrophils produce HGF led us to investigate their ...
OBJECTIVES/HYPOTHESIS Previous animal studies demonstrated that hepatocyte growth factor (HGF) has the potential to regenerate scarred vocal folds. In addition, HGF is now produced under a good manufacturing practice (GMP) procedure. Therefore, human clinical trials of HGF are warranted in patients with vocal fold scarring. In the current study, we investigated the pharmacokinetics and the loca...
The plasminogen system plays a crucial role in the repair of a variety of tissues, including skeletal muscle. We hypothesized that urokinase-type plasminogen activator (uPA) promotes muscle regeneration by activating hepatocyte growth factor (HGF), which, in turn, stimulates proliferation of myoblasts required for regeneration. In our studies, levels of active HGF and phosphorylation of the HGF...
We have reported that CXCL16, a recently discovered transmembrane chemokine, is expressed in human gingival fibroblasts (HGF). However, it is not known whether HGF express CXCR6, the receptor for CXCL16, or CXCL16 affects HGF biology. We have shown that HGF expressed CXCR6 by reverse transcription-polymerase chain reaction and flow cytometric analysis. Moreover, we elucidated that tumour necros...
Enhanced expression of hepatocyte growth factor by pulmonary ischemia-reperfusion injury in the rat.
Hepatocyte growth factor (HGF) has recently been noted to function as a pulmotrophic factor for lung regeneration. The present study was conducted to determine if HGF would be induced in a rat model of pulmonary ischemia-reperfusion (IR) injury, which was established by occlusion of the left lung, and to examine the significance of HGF in subsequent lung repair. The sham-operated rats underwent...
More than 95% of ovarian cancers originate from the epithelial cells on the surface of the ovary, which are termed ovarian surface epithelium (OSE). These OSE cells are modified peritoneal mesothelial cells separated from underlying ovarian surface stromal tissue by a basal lamina of dense collagenous connective tissue. Mesenchymal-epithelial cell interactions between stromal cells and OSE cell...
