The renin-angiotensin system (RAS) has been implicated in the development of metabolic syndrome. We investigated whether the hepatic RAS is modulated by exercise training and if this modulation improves the deleterious effects of fructose overload in rats. Male Wistar rats were divided into (n = 8 each) control (CT), exercise control (CT-Ex), high fructose (HFr) and exercise high fructose (HFr-Ex) groups. Fructose-drinking rats received D-fructose (100 g L(-1) ). After two weeks, CT-Ex and HFr-Ex rats were assigned to a treadmill training protocol at moderate-intensity for eight weeks (60 min day(-1) , four days/week)...

Co-infection with hepatitis B (HBV) and D virus (HDV) is associated with the most severe course of liver disease. Interferon represents the only treatment currently approved. However, knowledge about the impact of interferons on HDV in human hepatocytes is scant. Aim was to assess the effect of pegylated interferon alpha (peg-IFNα) and lambda (peg-IFNλ), compared to the HBV-polymerase inhibitor entecavir (ETV) on all HDV infection markers using human liver chimeric mice and novel HDV strand-specific qRT-PCR and RNA in situ hybridization assays, which enable intrahepatic detection of HDV RNA species...

UbcH7 is an ubiquitin-conjugating enzyme that interacts with parkin, an E3 ligase. The UbcH7-parkin complex promotes the ubiquitination and degradation of several proteins via the 26S proteasome. Cellular accumulation of the UbcH7-parkin targets alpha-synuclein, and synphilin-1 has been associated with Parkinson disease. In mouse liver, 2,3,7,8-tetrachlorodibenzo-p-dioxin, an aryl hydrocarbon receptor ligand, induces UbcH7 expression. Therefore, the aim of the present study was to determine whether 2,3,7,8-tetrachlorodibenzo-p-dioxin induces Ubch7 mRNA and UbcH7 protein expression in the mouse brain, to characterize the molecular mechanism, and the effect on synphilin-1 half-life...

BACKGROUND: The most common and severe disease causing allele of Alpha 1-Antitrypsin Deficiency (1ATD) is Z-1AT. This protein aggregates in the endoplasmic reticulum, which is the main cause of liver disease in childhood. Based on recent evidences and on the frequency of liver disease occurrence in Z-1AT patients, it seems that liver disease progression is linked to still unknown genetic factors. METHODS: We used an innovative approach combining yeast genetic screens with next generation exome sequencing to identify and functionally characterize the genes involved in 1ATD associated liver disease...

BACKGROUND: Cystathionine-γ-lyase (CSE) was shown to have a regulatory role in glucose metabolism. Circulatory shock can induce metabolic stress, thereby leading to hyperglycemia and mitochondrial dysfunction. In vitro data suggest an effect of high glucose on CSE expression. Therefore, the aim of this study was to investigate the effects of hyperglycemia on CSE expression in resuscitated murine septic shock. METHODS: Normo- (80-150 mg/dl) and hyperglycemic (>200 mg/dl) male C57/BL6J mice (n = 5-6 per group) underwent cecal ligation and puncture (CLP)-induced polymicrobial sepsis or sham procedure (n = 6 per group) and, 15 h afterwards, were anesthetized again, surgically instrumented and received intensive care treatment, including antibiotics, lung protective mechanical ventilation, circulatory support, and intravenous (i...

Chemokine (CC-motif) receptor-like 2 (CCRL2) is a decoy receptor and regulates the local responses of the chemokine chemerin. Recently our group has shown that the functional chemerin receptor, chemokine-like receptor 1 (CMKLR1), correlates with fibrosis and non-alcoholic steatohepatitis (NASH) score in males only. In our current study, we wanted to know whether CCRL2 shows similar correlations as CMKLR1. Therefore, we analyzed the hepatic expression of CCRL2 in murine NASH and in liver tissues obtained from 85 patients with non-alcoholic fatty liver disease (NAFLD) and 33 controls...

BACKGROUND: The relationship between dietary components and nonalcoholic fatty liver disease (NAFLD) needs to be further investigated. The potential health benefits of cardamom have been found in some studies. Cardamom showed beneficial effect on hepatomegaly, dyslipidemia, and fasting hyperglycemia in animals. However, some adverse effects of cardamom have been reported in animals. No previous human study had been conducted on the effects of cardamom in NAFLD. This study aims to determine the effects of green cardamom (Elettaria cardamomum) supplementation on blood glucose indices, lipids, inflammatory profiles, and liver function, especially by examining irisin, paraxonase-1 (PON1) and sirtuin-1 (Sirt1) in obese patients with NAFLD...

Nonalcoholic fatty liver disease (NAFLD) is characterized by excessive accumulation of hepatic lipids and oxidative injury of hepatocytes. Rutin is a natural flavonoid with significant roles in combating cellular oxidative stress and regulating lipid metabolism. The current study aims to investigate the molecular mechanisms underlying rutin's hypolipidemic and hepatoprotective effects in nonalcoholic fatty liver disease. Rutin treatment was applied to male C57BL/6 mice maintained on a high-fat diet and HepG2 cells challenged with oleic acid...

CLINICAL RELEVANCE: Cholangiocarcinoma is a cancer of bile duct cells for which no effective biomarker exists. Tumor masses are often not identifiable by imaging modalities as a result of the location of the tumor in the hilum of the liver or within the bile ducts. Because of the problems with obtaining a definitive tissue diagnosis, treatment and management decisions for patients with biliary strictures that may be malignant are difficult. The work presented here highlights the potential role of fucosylated fetuin-A as a biomarker of cholangiocarcinoma and may help in the early detection of this deadly cancer...

Tuberculosis (TB) is a major global health problem. Awareness of liver injury due to anti-TB therapy is vital because fulminant hepatic failure is a devastating and often fatal condition without liver transplantation. Here, we report for the first time, two patients of fatal liver injury due to anti-TB drugs in the presence of alpha-1 antitrypsin deficiency. Based on the triad of rapid loss in hepatocyte function, the onset of hepatic encephalopathy, and absence of a prior history of liver disease, the diagnosis of acute liver failure was established...

BACKGROUND: Alpha-1-antitrypsin deficiency (AATD) is a rare hereditary disease that is associated with a higher risk to develop chronic obstructive pulmonary disease and liver cirrhosis. Previous cross-sectional studies on AATD individuals have shown a relationship between worse St George's Respiratory Questionnaire (SGRQ) scores and elevated exacerbation rate or high cigarette consumption. There is a lack of longitudinal data on the relationship between the exacerbation rate and worsening of SGRQ during disease...
