AI Article Synopsis

  • The study measured human hepatocyte growth factor (hHGF) levels in patients with different liver diseases using primary cultured rat hepatocytes.
  • Patients with fulminant hepatic failure showed hHGF levels approximately nine times higher than those in normal serum, while those with acute hepatitis had levels three times higher, indicating a correlation with disease severity.
  • The findings suggest that elevated hHGF in serum is part of a self-defense mechanism that aids liver cell regeneration in response to various liver conditions.

Article Abstract

The levels of human hepatocyte growth factor (hHGF) in sera obtained from patients with various liver diseases were determined using adult rat hepatocytes maintained in primary culture. The mean hHGF activity for 22 patients with fulminant hepatic failure was about nine times greater than that found in normal human serum. The increase in serum hHGF activity seen in two patients with "acute-on-chronic" hepatitis was similar to that found in patients with fulminant hepatic failure. The serum level of hHGF from patients with acute hepatitis is related to the stage of their illness. The average value for 31 patients was about three times that of normal human serum. In some patients, the time course for the increase in serum hHGF activity was similar to that demonstrated for alpha-fetoprotein. The mean hHGF activity in serum for the 33 patients with chronic hepatitis and from 25 patients with liver cirrhosis was increased also compared with that of normal human serum. In addition, serum hHGF activity in three of seven patients studied after partial hepatectomy for a space-occupying lesion of the liver was increased. These data suggest that the increase in serum hHGF activity present in patients with various liver diseases reflects a self-defense mechanism that is involved in the process of liver cell regeneration.

Two-chain hepatocyte growth factor (tcHGF), the mature form of HGF, is associated with malignancy and anticancer drug resistance; therefore, its quantification is an important indicator for cancer diagnosis. In tumors, activated tcHGF hardly discharges into the systemic circulation, indicating that tcHGF is an excellent target for molecular imaging using positron emission tomography (PET). We recently discovered HGF-inhibitory peptide-8 (HiP-8) that binds specifically to human tcHGF with nanomolar affinity.

A human retinal microvascular endothelial-pericyte co-culture model to study diabetic retinopathy in vitro.

This human primary co-culture model using human retinal microvascular endothelial cells (hREC) and human retinal pericyte cells (hRP) aims to improve current understanding of the cellular changes occurring in the retinal microvasculature during diabetic retinopathy (DR). Currently, patients often present in clinic with late-stage DR, only when vision becomes impaired. Therefore, new strategies for earlier detection in clinic, combined with novel pharmaceutical and cellular interventions are essential in order to slow or halt the progression of DR from background to sight-threatening stage.

Background: Aberrant MET receptor tyrosine kinase (RTK) activation leads to invasive tumor growth in different types of cancer. Overexpression of MET and its ligand hepatocyte growth factor (HGF) occurs more frequently in glioblastoma (GBM) than in low-grade gliomas. Although we have shown previously that HGF-autocrine activation predicts sensitivity to MET tyrosine kinase inhibitors (TKIs) in GBM, whether it initiates tumorigenesis remains elusive.

Significantly enhanced recovery of acute liver failure by liver targeted delivery of stem cells via heparin functionalization.

Acute liver failure (ALF) occurs by insufficient detoxification of toxic materials in the liver, generating excess reactive oxygen species (ROS). Mesenchymal stem cell (MSC) therapy can be a promising approach for the treatment of liver diseases including ALF by anti-inflammatory activity and secretion of cytokines associated with tissue regeneration. However, the efficacy of MSC therapy is generally poor, mainly due to a low survival and engraftment of administered cells.

Peripheral nerve injury remains a common clinical problem with no satisfactory treatment options. Numerous studies have shown that hepatocyte growth factor (HGF) exerts neurotrophic effect in motor, sensory, and parasympathetic neurons in addition to mitogenic, morphogenic, angiogenic, antiapoptotic, antifibrotic, and anti-inflammatory effect on various tissues and cells. In our study we examined efficacy of gene therapy with HGF-bearing plasmid (pC4W-hHGF) to improve consequences of traumatic nerve injury in mice.
