Diabetes Mellitus (DM) is an incurable disease that can be prevented clinically from worsening. This based on classification related to pancreatic damage in total or partial so the impact insulin production. Glucose transporter a protein glucose uptake outside cell into and provides important role body's homeostasis. transporter-2 (GLUT-2) found pancreas, liver, kidney. Parameters used are expr...

The uptake and internalization of a triglyceride emulsion by rat hepatocytes in culture less than 24 hr was either inhibited or uninfluenced by apoE. ApoE significantly increased the uptake of these emulsions in later cultures. Specific low density lipoprotein (LDL) binding was similar for hepatocyte monolayers prior to and after 24 hr. Rat hepatocytes in culture for 2 days, which were treated ...

c-raf is a serine-threonine kinase and a downstream effector of ras signaling. This kinase plays an essential role in cell proliferation, differentiation, and apoptosis. In the past, we reported induction of c-raf gene expression in rat liver cancer on treatment with a mixture of aryl hydrocarbon receptor (AhR) agonists. This prompted our interest in investigating the role of AhR in the transcr...

Genetic constructs with promoters fused to reporter genes for simultaneous monitoring of cellular events have been the focus of attention in recent years. Adenoviral vectors, which have distinctive characteristics, have been used to monitor the differentiation of stem cells in vitro. In the present study, a modified adenoviral vector was constructed, containing a mouse, rat, and human general a...

PURPOSE Retrorsine selectively inhibits hepatocyte proliferation and following liver injury evokes small hepatocyte-like progenitor cells. The aim of this study is to find out whether endogenous extrahepatic cells contribute to small hepatocyte-like progenitor cells after retrorsine treatment. METHODS Wild-type Lewis rat liver exposed to retrorsine was transplanted into GFP transgenic Lewis r...

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...

The rat is an excellent model for gene therapy because there are many rat models for human diseases. We have developed a simple and efficient method to deliver genes to the rat liver using recombinant retroviral vectors. A 70% partial hepatectomy followed by retroviral infusion into the portal vein results in 10-15% hepatocyte transduction in vivo. This is 10 times more efficient than in the mo...

The ability of 10 muM epinephrine or isoproterenol to stimulate cyclic AMP accumulation was decreased in hepatocytes isolated from hyperthyroid (triiodothyronine treated) as compared to euthyroid rats. In the presence of methylisobutylxanthine, epinephrine or isoproterenol-stimulated cyclic AMP accumulation was approximately 65% lower in hyperthyroid as compared with euthyroid rat hepatocytes. ...
