The data presented in this brief report support the research article "Altered mitochondrial and peroxisomal integrity in lipocalin-2-deficient mice with hepatic steatosis" [1, doi: 10.1016/j.bbadis.2017.04.006]. We tested whether the absence of Lipocalin-2 (LCN2) could dysregulate the phosphatidylinositol 3-kinase/protein kinase B (PI3K-PKB) pathway and hepatic homeostasis in Non-Alcoholic-Steatohepatitis (NASH). The article highlights the role of LCN2 in hepatic homeostasis.

Psoriasis is a chronic inflammatory skin disease affecting 2-4 % of Central European population. Nowadays, we know that psoriasis is not limited to the skin but is connected with several comorbidities like, psoriatic arthritis (around 25 %), Crohn's disease, ulcerative colitis, Bechterev, non-alcoholic liver steatosis, psychiatric disorders and mainly diseases of the so called metabolic syndrome, like diabetes mellitus type 2, arterial hypertension or dyslipidemia. In the last years, new information is arising which connect psoriasis with sleep apnoe and chronic obstructive pulmonary disease...

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease and is associated with the worldwide epidemics of obesity, diabetes and cardiovascular diseases. NAFLD ranges from benign fat accumulation in the liver (steatosis) to non-alcoholic steatohepatitis (NASH), and cirrhosis which can progress to hepatocellular carcinoma and liver failure. Mass spectrometry and magnetic resonance spectroscopy-coupled stable isotope-based flux studies provide new insights into the understanding of NAFLD pathogenesis and the disease progression...

Non-alcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis, impaired insulin sensitivity and chronic low-grade inflammation. However, the pathogenic mechanism of NAFLD is poorly understood, which hinders the exploration of possible treatments. Here, we first report that ubiquitin-specific protease 18 (USP18), a member of the deubiquitinating (DUB) enzyme family, plays regulatory roles in NAFLD progression. The expression of USP18 was down-regulated in the livers of non-alcoholic steatohepatitis (NASH) patients and high-fat diet (HFD) induced or genetically obese mice...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease and is found in 70% of obese people. The evidence available to date suggests that bariatric surgery could be an effective treatment by reducing weight and also by improving metabolic complications in the long term. This work aimed to compare, in a diet-induced NAFLD animal model, the effect of both sleeve gastrectomy (SG) and very-low calorie diet (VLCD). METHODS: Thirty-five Wistar rats were divided into control rats (n = 7) and obese rats fed a high-fat diet (HFD)...

Nonalcoholic fatty liver disease (steatosis) is the most prevalent liver disease in the Western world. One of the advanced pathologies is non Non-alcoholic steatohepatitis (NASH), which is associated with induction of the Unfolded protein response (UPR) and disruption of autophagic flux. However, the mechanisms by which these processes contribute to the pathogenesis of human diseases are unclear. Herein we identify the α isoform of the inhibitor of Brutons tyrosine kinase (IBTKα) as a member of the UPR whose expression is preferentially translated during endoplasmic reticulum (ER) stress...

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is a common and strong risk factor for cardiovascular disease and hepatocellular carcinoma. The rapid acceleration of the increase in NAFLD prevalence has exceeded the trends observed for obesity, and has been driven by multiple factors. The aim of this study was to investigate the correlation between the serum levels of folic acid, the endogenous source of methyl groups for DNA methylation, and NAFLD in Chinese adults. METHODS: The correlations between the serum folic acid levels and NAFLD were investigated in two independent cohorts of 70 subjects who underwent a liver biopsy and 130 subjects with varying liver fat contents, as measured using proton magnetic resonance spectroscopy ((1)H-MRS)...

In non-alcoholic steatohepatitis (NASH), hepatic stellate cells (HSC) differentiate into myofibroblast-like cells that cause fibrosis, which predisposes patients to cirrhosis and hepatocellular carcinoma. Thus, modeling interactions between activated HSCs and hepatocytes in vitro can aid in the development of anti-NASH/fibrosis therapeutics and lead to a better understanding of disease progression. Species-specific differences in drug metabolism and disease pathways now necessitate the supplementation of animal studies with data acquired using human liver models; however, current models do not adequately model the negative effects of primary human activated HSCs on the phenotype of otherwise well-differentiated primary human hepatocytes (PHHs) as in vivo...

BACKGROUND: Increased visceral adiposity is strongly associated with non-alcoholic fatty liver disease (NAFLD). However, little attention has been paid to the association between the change in subcutaneous adipose mass and the progression of non-alcoholic fatty liver disease (NAFLD). We aimed to investigate whether increased subcutaneous adipose tissue (gynoid fat mass) could be protective against the progression of NAFLD in Japanese patients with type 2 diabetes. METHODS: This is a retrospective observational study of 294 Japanese patients with type 2 diabetes (65 ± 10 years old, 40% female)...

Non-alcoholic fatty liver disease (NAFLD) is characterized by liver fat accumulation and non-alcoholic steatohepatitis (NASH) with inflammation and fibrosis, which may lead to cirrhosis also in childhood. NAFLD/NASH in children are related to obesity and the metabolic syndrome, and incidence and prevalence are expected to increase. Children having liver steatosis and elevated liver enzymes are most often asymptomatic, and a liver biopsy is necessary for correct diagnosis and staging. The treatment should focus on lifestyle changes, as pharmacological therapy needs further evaluation...
