Introduction. Raw and processed Notoginseng Radix Et Rhizome (NRR) have been widely used in treatment of metabolic syndromes and related disease, including nonalcoholic fatty liver disease (NAFLD). This study was designed to investigate lipid regulation effects of raw and processed NRR in steatotic L02 cell. Materials and Methods. Steatotic L02 cells were obtained after being cultured with 5% f...

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in industrialized countries and is increasing in prevalence. The pathomechanisms, however, are poorly understood. This study assessed the unexpected role of the Hedgehog pathway in adult liver lipid metabolism. Using transgenic mice with conditional hepatocyte-specific deletion of Smoothened in adult mice, we showed that...

Overnutrition is one of the major causes of non-alcoholic fatty liver disease (NAFLD). NAFLD is characterized by an accumulation of lipids (triglycerides) in hepatocytes and is often accompanied by high plasma levels of free fatty acids (FFA). In this study, we compared the energy metabolism in acute steatotic and non-steatotic primary mouse hepatocytes. Acute steatosis was induced by pre-incub...

We examined whether angiotensin (Ang) II receptor antagonists could be considered a therapeutic strategy in steatotic and nonsteatotic livers in conditions of partial hepatectomy under ischemia-reperfusion (I/R), which is commonly applied in clinical practice to reduce blood loss. We report that Ang II type I receptor (AT1R) antagonist, but not Ang II type II receptor (AT2R) antagonist, increas...

Oxidative stress and mitochondrial dysfunction play an important role in the pathogenesis of nonalcoholic fatty liver disease and toxic liver injury. The present study was designed to evaluate the effect of exogenous inducer of oxidative stress (tert-butyl hydroperoxide, tBHP) on nonfatty and steatotic hepatocytes isolated from the liver of rats fed by standard and high-fat diet, respectively. ...

The small heterodimer partner (SHP) (NR0B2) is an atypical nuclear receptor that lacks a DNA-binding domain. It interacts with and inhibits many transcription factors, affecting key metabolic processes, including bile acid, cholesterol, fatty acid, and drug metabolism. Our aim was to determine the influence of steatotic drugs and nonalcoholic fatty liver disease (NAFLD) on SHP expression and in...

The present study attempted to define the role of hepatic Niemann-Pick C1-like 1 (NPC1L1), a cholesterol transporter, in hepatic insulin resistance as well as hepatic steatosis. The inhibition of NPC1L1 and its molecular consequences were examined in Zucker obese fatty (ZOF) rats and cultured steatotic hepatocytes using ezetimibe, a pharmacoloigcal inhibitor of NPC1L1, and short hairpin RNA (sh...

Reactive Oxygen Species (ROS) are key mediators of ischemia-reperfusion injury but also required for the induction of the stress response that limits tissue injury and underlies the protection provided by ischemic-preconditioning protocols. Liver steatosis is an important risk factor for liver transplant failure. Liver steatosis is associated with mitochondrial dysfunction and excessive mitocho...

The application of liver stiffness measurement (LSM) by transient elastography (TE) in general population remains to clarify. This cohort study aimed to examine the usefulness of TE and to identify factors associated with significant liver fibrosis in community-based population.We conducted a hepatitis screening program in 2 remote villages of Southern Taiwan. All residents participated volunta...

Liver biopsy is important in the perioperative management of liver transplantation with regard to the preoperative evaluation of donor liver graft, especially to rule out steatotic liver, and the postoperative diagnosis of acute cellular rejection (ACR), especially to differentiate ACR from other causes of liver dysfunction. In both situations, liver biopsy is mandatory to confirm the diagnosis...
