We investigated whether or not beta and alpha adrenergic agonists could affect proliferation of adult rat hepatocytes induced by hepatocyte growth factor (HGF) during the early and late phases of primary culture. Adult rat hepatocytes underwent significant DNA synthesis after culture with 5 ng/ml HGF for 3 h at a low cell density (3.3 x 10(4) cells/cm2). Under these culture conditions, the numb...
Hepatocyte growth factor (HGF) is a novel potential therapy for improving bone health in patients with type II diabetes and hypertension, but its effect on the molecular structure not revealed yet. Here, X-ray absorption near edge (XANES) spectroscopy was used to explore effects elicited by HGF chemical structure. This study assessed local calcium (Ca) phosphorus (P) coordination of diabetic hy...
We have used a combined biochemical and morphological approach to establish the suitability of certain endogenous and exogenous domain markers for monitoring the separation of rat hepatocyte plasma membrane domains in sucrose density gradients. As endogenous domain markers, we employed two of the integral plasma membrane protein antigens, HA 4 and CE 9, localized to the bile canalicular and sin...
Isolated rat and human hepatocytes in primary culture were shown to metabolize AAF to reactive intermediates which damaged hepatocyte DNA. A significant increase in unscheduled DNA synthesis was detectable by autoradiography in rat and human hepatocytes exposed to concentrations of AAF as low as 1 microM. When rat hepatocytes were plated over confluent monolayers of human fibroblasts and expose...
Hydroxamic acid (HA)-based histone deacetylase (HDAC) inhibitors, with trichostatin A (TSA) as the reference compound, are potential antitumoral drugs and show promise in the creation of long-term primary cell cultures. However, their metabolic properties have barely been investigated. TSA is rapidly inactivated in rodents both in vitro and in vivo. We previously found that 5-(4-dimethylaminobe...
Liver cirrhosis represents a worldwide health problem and is a major cause of mortality. Cirrhosis is the result of extensive hepatocyte death and fibrosis induced by chronic alcohol abuse and hepatitis B and C viruses. Successful gene therapy approaches to this disease may require both reversal of fibrosis and stimulation of hepatocyte growth. Urokinase-type plasminogen activator (uPA) may ser...
