The features of viral hepatitis B (HB) and C (HC) in the initial making these diagnoses three age groups men women (25-30, 31-55 years old for 31-60 men, over 55 60 men) were studied. High levels bilirubin blood serum all indicated damage functions hepatocytes, especially with B, C. high ALT activity an increase cytolytic processes liver hepatocytes HB HC, younger group, middle-aged groups. con...
Abstract Mitochondrial fusion and fission, which are strongly related to normal mitochondrial function, referred as dynamics. defects in the liver cause a non-alcoholic steatohepatitis-like phenotype cancer. However, whether fission defect directly impair function stimulate disease progression, too, is unclear. Dynamin-related protein 1 (DRP1) key factor controlling fission. We hypothesized tha...
The metabolic activation of the carcinogens N-nitrosobis(2-oxopropyl)amine (BOP) and N-nitroso(2-hydroxypropyl)(2-oxopropyl)amine (HPOP) by Fischer rat and Syrian hamster hepatocytes was investigated in order to determine the existence of species differences in the induction of cell mutation. The conversion of BOP and HPOP into forms mutagenic to V79 cells was studied by using the hepatocyte-me...
In this study, activation of the mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) signalling pathway was analyzed in proliferating rat hepatocytes both in vivo after partial hepatectomy and in vitro following epidermal growth factor (EGF)-pyruvate stimulation. First, a biphasic MEK/ERK activation was evidenced in G(1) phase of hepatocytes from regenerati...
Objective: Hepatic glucose release plays a potential role in hyperglycemia in type 2 diabetes (T2D) patients. The aim of this experimental study was to determine the effect of 6 weeks of high-intensity interval training (HIIT) on fasting levels of glucose and insulin as well as glucokinase (GCK) expression in liver tissue in obese T2D rats. Materials and Methods: T2D was induced by a high-fat ...
The increasing worldwide aquaculture output and concomitant decrease in the stocks of feedgrade fish used for fish oil production has made fish oil replacement in feeds a priority for the aquaculture industry. The regulation of fatty acid metabolism in fish is important in order to determine strategies for the best use of plant oils in diets for commercially important cultured fish species. We ...
Studies of low density lipoprotein (LDL) metabolism in nonhuman model systems have indicated that the mammalian liver has dual mechanisms for the uptake and regulation of the concentration of plasma LDL. Heretofore, direct evaluation of lipoprotein uptake mechanisms in human hepatocytes has not been possible. In order to compare hepatocyte LDL uptake with fibroblast LDL metabolism, human hepato...
Lipopolysaccharide (LPS)-binding protein (LBP) has been reported to be an acute-phase protein. LBP binds to LPS with a high affinity; LPS-LBP complexes then interact with the receptor CD14, resulting in increased expression of LPS-inducible genes. Hepatocytes represent a major source of LBP, but little is known about the regulation of rodent hepatocyte LBP synthesis. In these studies, undertake...
Hepatocellular carcinoma almost always arises in chronically inflamed livers. We developed a culture model to study the role of non-parenchymal cells (NPCs) for inflammation-driven hepatocarcinogenesis. Rats were treated with the carcinogen N-nitrosomorpholine, which induced initiated hepatocytes expressing the marker placental glutathione-S-transferase (GSTp). After 21 days two preparations of...
To investigate host and viral mechanisms determining hepadnaviral persistence and hepatocarcinogenesis, we developed a mouse model by transplanting woodchuck hepatocytes into the liver of mice that contain the urokinase-type plasminogen activator transgene (uPA) and lack mature B and T lymphocytes due to a recombination activation gene 2 (RAG-2) gene knockout. The woodchuck hepatocytes were tra...
