standardization of induction of oxidative stress with fenton mixture (fm) in isolated perfused rat kidney and the antioxidant effect of terminalia arjuna bark in the isolated oxidatively stressed rat kidney has been evaluated. six groups each containing eight isolated perfused rat kidneys were used for the present study and the oxidative stress was induced by perfusing the isolated kidneys with...

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...

     Dacarbazine (DTIC) is a synthetic chemical antitumor agent which is used to treat malignant melanoma and Hodgkin’s disease. DTIC is a prodrug which is converted to an active form undergoing demethylation by liver enzymes. The active form prevents the progress of disease via alkylation of DNA strand. In the structure of this drug, the imidazole ring, a triazen chain and carboxamide group ex...

Trenimon belongs to a class of aziridinylbenzoquinone anticancer drugs that cross the blood-brain barrier. In this study we have investigated the molecular mechanisms for trenimon-induced toxicity in aerobic versus hypoxic conditions with the use of freshly isolated rat hepatocytes. The following evidence suggests the mechanisms for trenimon detoxification involves reduction by DT-diaphorase, w...

The correct functioning of the liver is ensured by the setting and the maintenance of hepatocyte polarity. The complex polarity of hepatocyte is characterized by the existence of several basolateral and apical poles per cell. Many in vitro models are available for studying hepatocyte polarity. But which are the more suitable? To answer this question, we wished to identify criteria which determi...

The metabolic profile of DFU [5,5-dimethyl-3-(3-fluorophenyl)-4-(4-methylsulphonyl)phenyl-2(5H)-furanone], a potent and selective COX-2 inhibitor, was characterized using in vitro microsomal and hepatocyte incubations. A single product, corresponding to p-hydroxylation, p-OH-DFU [(5,5-dimethyl-3-(3-fluoro-4-hydroxyphenyl)-4-(4-methylsulphonyl)phenyl-2(5H)-furanone)], was produced in rat microso...

The typical proliferative response of hepatocytes to tumor necrosis factor (TNF) can be converted to a cytotoxic one by transcriptional arrest. Although NF-kappaB activation is critical for hepatocyte resistance to TNF toxicity, the contribution of other TNF-inducible transcription factors remains unknown. To determine the function of c-Myc in hepatocyte sensitivity to TNF, stable transfectants...

Drug metabolism studies and liver tissue engineering necessitate stable hepatocyte cultures that express liver functions for a minimum of 4 days to 3 weeks. Current techniques, using different biomaterials and geometries, that maintain hepatocellular function in vitro exhibit a low cell density and functional capacity per unit volume. Herein we investigated a well-defined synthetic peptide that...

This study investigated the efficacy and feasibility of inducing the differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) into hepatocyte-like cells in vitro using Sprague Dawley rats, as a model of hepatocyte generation for cell transplantation. BMSCs were isolated and grown using the adherent method and exposed to 5 or 10% liver tissue homogenate, before being collected for a...
