endoplasmic reticulum (er) stress provides abnormalities in insulin action, inflammatory responses, lipoprotein b100 degradation and hepatic lipogenesis. excess accumulation of triglyceride in hepatocytes may also lead to disorders such as non-alcoholic fatty liver disease (nafld) and nonalcoholic steatohepatitis (nash). opioid peptides are involved in triglyceride and cholesterol dysregulat...

liver or hepatic transplantation (lt) is the replacement of a diseased liver with part or whole healthy liver from another person (allograft). human liver transplants were first performed by thomas starzl in the united states and roy calne in cambridge, england in 1963 and 1967, respectively. liver transplantation is a viable treatment option for end-stage liver disease and acute liver failure....

BACKGROUND Surgical procedures such as liver resection and liver transplantation are the first-line treatments for hepatocellular carcinoma (HCC) patients. However, the high incidence of tumor recurrence and metastasis after liver surgery remains a major problem. Recent studies have shown that hepatic ischemia-reperfusion (I/R) injury and endothelial progenitor cells (EPCs) contribute to tumor ...

OBJECTIVE Antidepressant drugs can cause drug-induced liver injury (DILI). The authors review clinical data relevant to antidepressant-induced liver injury and provide recommendations for clinical practice. METHOD A PubMed search was conducted for publications from 1965 onward related to antidepressant-induced liver injury. The search terms were "liver injury," "liver failure," "DILI," "hepat...

The coronavirus disease-2019 (COVID-19) pandemic is a public health threat impacting people all over the world. Although severe acute respiratory syndrome (SARS-CoV-2) was identified as virus for system, it might be responsible digestive symptoms associated with COVID-19. Common gastrointestinal in COVID-19 patients are anorexia, vomiting, nausea, abdominal pain, and diarrhea, addition to abnor...

Many studies have shown that the pathogenesis of liver injury includes oxidative stress. MicroRNA-122 may be a marker for the early diagnosis of drug-induced liver injury. However, the relationship between microRNA-122 and oxidative stress in anti-tuberculosis drug-induced liver injury remains unknown. We measured changes in tissue microRNA-122 levels and indices of oxidative stress during live...

Severe halothane (HAL)-induced hepatotoxicity occurs in one in 6000-30,000 patients by an unknown mechanism. Female sex is a risk factor in humans and rodents. We tested the hypothesis that a sex difference in natural killer (NK) cell activity contributes to HAL-induced liver injury. HAL (15 mmol/kg, ip) treatment resulted in severe liver injury by 12 h in female, wild-type BALB/cJ mice, and th...

Neutrophil adhesion and migration are critical in hepatic ischemia/reperfusion (I/R) injury. Despite very strong preclinical data, recent clinical trials failed to show a protective effect of anti-adhesion therapy in reperfusion injury. Therefore, the aim of this study was to assess the role of CD44 in neutrophil infiltration and liver injury from hepatic I/R. In this study, using a partial hep...

NKT cells are remarkably abundant in mouse liver. Compelling experimental evidence has suggested that NKT cells are involved in the pathogenesis of many liver diseases. Activation of NKT cells with alpha-galactosylceramide (alpha-GalCer) causes liver injury through mechanisms that are not well understood. We undertook studies to characterize the key pathways involved in alpha-GalCer-induced liv...

P2X7 is important in inflammation and tissue injury. The aim of the present study was to investigate the effect of P2X7 inhibition, using a specific inhibitor (A438079) to prevent the development of liver injury and fibrosis in a mouse model of liver fibrosis. The mouse liver fibrosis model was induced by carbon tetrachloride (CCl4). Mice received subcutaneous administration of vehicle (saline/...
