Introduction  Insulin-like growth factor I (IGF-I) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. IGF-I plays the roles via the receptor (IGF-IR) signaling pathway. IGF-IR unlike IGF-I is expressed strongly in the developing liver, but much more weakly in adults. Objective:  We hypothesi...

Chronic liver Injury (CLI) and its end-stages, cirrhosis, hepatocellular carcinoma (HCC), are leading causes of morbidity mortality worldwide with enormous socioeconomic costs. Clinical management chronic injury is dependent on the extent fibrosis. Liver biopsy, gold standard, still recommended in most patients. disease diagnosis can generally be made using a carefully obtained history, physica...

MicroRNAs (miRNAs) are small RNA molecules that function to modulate the expression of target genes, playing important roles in a wide range of physiological and pathological processes. The miRNAs in body fluids have received considerable attention as potential biomarkers of various diseases. In this study, we compared the changes of the plasma miRNA expressions by acute liver injury (hepatocel...

BACKGROUND At present, a large number of studies indicate that high dose ionizing radiation exposure is an important risk factor for liver damage. Whether protracted exposure to low external doses of ionizing radiation could induce liver injury is unclear. The aim of this study was to assess the risk of liver injury following protracted exposure to occupational radiation compared to a group of ...

Hepatocytes provide most liver functions, but they can also proliferate and regenerate the liver after injury. However, under some liver injury conditions, particularly chronic liver injury where hepatocyte proliferation is impaired, liver stem cells (LSCs) are thought to replenish lost hepatocytes. Conflicting results have been reported about the identity of LSCs and their contribution to live...

Transforming growth factor-beta1 (TGF-β1) is a major factor in pathogenesis of chronic hepatic injury. Carbon tetrachloride (CCl4) is a liver toxicant, and CCl4-induced liver injury in mouse is a classical animal model of chemical liver injury. However, it is still unclear whether TGF-β1 is involved in the process of CCl4-induced acute chemical liver injury. The present study aimed to evaluate ...

BACKGROUND Autochthonous hepatitis E has been observed with growing incidence in industrialized countries. Hepatitis E virus infection causes an acute hepatitis with spontaneous resolution in the majority of cases. However, in individual cases, hepatitis E may lead to life-threatening acute liver failure. In this report, we describe a case of acute liver injury caused by an autochthonous hepati...

Background: There are many reports regarding to effects of Granulocyte colony-stimulating factor (G-CSF) and stem cell factor (SCF)alone in liver repair .But conflicting data have been reported regarding the role of growth factors such as G-CSF and SCF in the liver regeneration system. Also, there is not such data regarding to effects of co-administration both of G-CSF and SCF in the liver dama...
