Despite the progress in our understanding of genes essential for stem cell regulation and development, little is known about the factors secreted by stem cells and their effect on tissue regeneration. In particular, the factors secreted by human CD34+ cells remain to be elucidated. We have approached this challenge by performing a cytokine/growth factor microarray analysis of secreted soluble f...
The factors influencing lymphocyte trafficking to the liver lobule during chronic hepaititis C virus (HCV) infection are currently not well defined. Interferon-gamma-inducible protein 10 (IP-10), a chemokine that recruits activated T lymphocytes, has recently been shown by in situ hybridization to be expressed in the liver during chronic HCV infection. This study sought to define the cellular s...
Genotype 5 hepatitis C has been poorly studied despite its worldwide spread. We have analyzed the early kinetics of genotype 5 hepatitis C virus RNA during pegylated interferon/ribavirin treatment in a 59-year-old man with active liver necroinflammatory changes and advanced liver fibrosis. The patient had a high viral load but a small serum level of hepatitis C core antigen. On combination anti...
OBJECTIVE The hepatocyte growth factor (HGF) is a pleiotropic cytokine produced by hepatic stellate cells and implicated in liver regeneration and fibrosis. Serum levels of HGF vary in liver diseases, reflecting hepatic damage and hepatocellular dysfunction. In this study, serum levels of HGF and the relationship between HGF and biochemical, histological and virological data, have been analysed...
Viral hepatitis B (HBV) is a major public health problem worldwide. Indeed, the World Health Organization (WHO) estimates that more than 2 billion number of people who have been exposed to this virus, about 30% world population, 18% in sub-Saharan Africa and 41% Asia, which 5% with chronic infection or 300-350 million. So HBV prevalence 5.4% globally, against 1% for HIV 3% C. More 1 million the...
BACKGROUND MicroRNA-21 (miR-21) is up-regulated in tumor tissue of patients with malignant diseases, including hepatocellular carcinoma (HCC). Elevated concentrations of miR-21 have also been found in sera or plasma from patients with malignancies, rendering it an interesting candidate as serum/plasma marker for malignancies. Here we correlated serum miR-21 levels with clinical parameters in pa...
BACKGROUND Increased hepatic iron is assumed to potentiate progression towards liver fibrosis in chronic hepatitis C virus (HCV) infection. In this study we have evaluated the potentiating effect of marked hepatic iron overload and chronic HCV infection on hepatic fibrosis in thalassemic patients. METHODS Liver biopsies of one group of patients with beta thalassemia major and chronic HCV infe...
Integrated hepatitis B virus (HBV) DNA is present in many hepatocellular carcinomas (HCC), suggesting that HBV has a direct oncogenic effect through interaction with transformation-associated genes. Many genes involved in cell cycle regulation (cyclins, kinases, negative regulators, Wnt-beta-catenin) and the transcriptome profile are deregulated or altered in most HCC patients. The HBx protein,...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
Macrophage migration inhibitory factory (MIF) regulates macrophage accumulation at sites of injury and can promote the inflammatory response. We studied MIF expression in the intragastric feeding rat model for alcoholic liver injury. Male and age-matched female rats were fed ethanol or dextrose with fish oil. Two groups of male rats were fed medium-chain triglycerides with ethanol or dextrose. ...
