Epithelial Cell Adhesion Molecule (EpCAM), or CD326, is a trans-membrane glycoprotein expressed by multiple normal epithelia as well as carcinoma. Human hepatic stem cells and bile duct epithelium of the liver are EpCAM positive. In tumor cell lines, its intracellular domain can be released after cleavage of the extracellular domain. Within the cell nucleus it induces cell proliferation, but cleavage depends on cell contact. Fragments of various lengths have been described in tumor cells. Despite of its described important role in proliferation in tumor cells, there is not much known about the expression and role of EpCAM fragments in primary human liver cells...

Nonalcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease with manifestation of over-accumulation of fat in liver. Increasing evidences indicate that NAFLD may be in part caused by malfunction of very low density lipoprotein (VLDL) secretion. Hepatocyte nuclear factor 4α (HNF4α), a nuclear receptor protein, plays an important role in sustain hepatic lipid homeostasis via transcriptional regulation of genes involved in secretion of VLDL, such as apolipoprotein B (ApoB). However, the exact functional change of HNF4α in NAFLD remains to be elucidated...

BACKGROUND: Psoriasis associates several extra-cutaneous manifestations. Little is known about hepatic parameters specifically associated with psoriasis. OBJECTIVE: To study whether psoriasiform dermatitis is associated with liver injury. METHODS: We studied liver parameters of inflammation and fibrosis in a murine model of psoriasiform dermatitis induced by topical application of imiquimod for nine weeks. RESULTS: Topical treatment with imiquimod induced a form of psoriasiform dermatitis reminiscent of the human disorder, characterized by thickened and scaly skin, psoriasiform epidermal hyperplasia, altered keratinocyte differentiation, and cutaneous overexpression of interleukin-17A...

PURPOSE: Major hepatic resections are performed for primary hepatobiliary malignancies, metastatic disease, and benign lesions. Patients with chronic liver disease, including cirrhosis and steatosis, are at an elevated risk of malnutrition and impaired strength and exercise capacity, deficits which cause increased risk of postoperative complications and mortality. The aims of this report are to discuss the pathophysiology of changes in nutrition, exercise capacity, and muscle strength in patient populations likely to require major hepatectomy, and review recommendations for preoperative evaluation and optimization...

Cirrhosis is the terminal stage of hepatic diseases and is prone to develop into hepatocyte carcinoma. Increasing evidence suggests that the transplantation of dental pulp stem cells (DPSCs) may promote recovery from cirrhosis, but the key regulatory mechanisms involved remain to be determined. In this study, we overexpressed human hepatocyte growth factor (hHGF) in primary rat DPSCs and evaluated the effects of HGF overexpression on the biological behaviors and therapeutic efficacy of grafted DPSCs in cirrhosis...

Pathogenesis of non-alcoholic fatty liver disease (NAFLD) is influenced by predisposing genetic variations, dysmetabolism, systemic oxidative stress, and local cellular and molecular cross-talks. Patatin-like phospholipase domain containing 3 (PNPLA3) gene I148M variant is a known determinant of NAFLD. Aims were to evaluate whether PNPLA3 I148M variant was associated with a specific histological pattern, hepatic stem/progenitor cell (HpSC) niche activation and serum oxidative stress markers. Liver biopsies were obtained from 54 NAFLD patients...

BACKGROUND: The persistent scarcity of donors has prompted liver transplantation teams to find solutions for increasing graft availability. We report our experience of liver transplantations performed with grafts from older donors, specifically over 70 and 80 years old. PATIENTS AND METHODS: We analyzed our prospectively maintained single-center database from January 1, 2005, to December 31, 2014, with 380 liver transplantations performed in 354 patients. Six groups were composed according to donor age: <40 (n = 84), 40 to 49 (n = 67), from 50 to 59 (n = 62), from 60 to 69 (n = 76), from 70 to 79 (n = 64), and ≥80 years (n = 27)...

INTRODUCTION: Hepatitis C virus (HCV)-related cirrhosis remains the commonest indication for liver transplantation worldwide, yet few studies have investigated the impact of donation after circulatory death (DCD) graft use on HCV recurrence and patient outcomes. DCD grafts have augmented the limited donor organ pool and reduced wait-list mortality, although concerns regarding graft longevity and patient outcome persist. METHODS: This was a single-center study of all HCV + adults who underwent DCD liver transplantation between 2004 and 2014...

BACKGROUND: Despite the progressively increasing gap between patients waiting for liver transplant under the Model for End-stage Liver Disease MELD system and the availability of deceased donor organs, the use of right extended split liver grafts (RESLG) has not been accepted by all centers. In this study, we compared the results obtained using RESLG vs a group of matched whole liver graft (WLG) recipients at a single center in Latin America. METHODS: A single-center retrospective review performed between August 2009 and December 2015...

BACKGROUND: Inadequate hemostasis during living donor liver transplantation (LDLT) is mainly due to coagulopathy but may also include fibrinolysis. The purpose of this study was to determine the incidence of fibrinolysis and assess its relevance to mortality in LDLT. METHODS: The incidence and prognosis of fibrinolysis were retrospectively studied in 76 patients who underwent LDLT between April 2010 and February 2013. Fibrinolysis was evaluated and defined by maximum lysis (ML) >15% within a 60-minute run time using thromboelastometry (ROTEM)...

REVIEW
Carlo Selmi, Elena Generali, Merrill Eric Gershwin
Autoimmune liver diseases coexist with rheumatic disorders in approximately 30% of cases and may also share pathogenic mechanisms. Autoimmune liver diseases result from an immune-mediated injury of different tissues, with autoimmune hepatitis (AIH) targeting hepatocytes, and primary biliary cholangitis (PBC) and primary sclerosing cholangitis targeting cholangiocytes. Sjogren syndrome is diagnosed in 7% of AIH cases and serologic autoimmunity profiles are a common laboratory abnormality, particularly in the case of serum antimitochondrial (PBC) or anti-liver kidney microsomal antibodies (AIH)...

Patrick R Wood, Liron Caplan
A variety of gastrointestinal adverse drug reactions are seen in nearly all conventional antirheumatic medications, ranging from nausea to life-threatening drug-induced liver injury. Rheumatologists should be particularly familiar with hepatotoxicity associated with long-term methotrexate use, and the range of unique hepatic, biliary, and pancreatic manifestations associated with azathioprine. Hepatitis B virus reactivation is the most serious gastrointestinal disease risk associated with many biological therapies, particularly rituximab...

Liron Caplan, Kristine A Kuhn
The association of inflammatory arthritis with intestinal pathology extends back more than 100 years. This association is now supported by epidemiologic studies demonstrating an elevated prevalence of inflammatory bowel disease in spondyloarthritis and vice versa, compared with the general population. Genetic and intestinal microbiome studies have further linked these diseases. Although diabetes and nonalcoholic fatty liver disease disproportionately affect individuals with psoriatic arthritis, diseases of the esophagus, stomach, pancreas, and liver are not particularly common in spondyloarthritis...

BACKGROUND: To ensure sustainability of aquaculture, plant-based ingredients are being used in feeds to replace marine-derived products. However, plants contain secondary metabolites which can affect food intake and nutrient utilisation of fish. The application of nutritional stimuli during early development can induce long-term changes in animal physiology. Recently, we successfully used this approach to improve the utilisation of plant-based diets in diploid and triploid Atlantic salmon...

Chrononutrition is the science of nutrition based on chronobiology. Numerous epidemiological studies have shown that fish oil (FO) reduces the risk of cardiovascular events through various actions such as lowering triglycerides. The present study aimed to determine the time of day when the hypertriglyceridemia-decreasing ability of FO is optimal in mice. A high-fructose diet (HFrD) that induces hyperlipidemia in mice was replaced with the same diet containing 4% FO (HFrD-4% FO) at different times of the day for 2 weeks as described below...

Cholesterol is a critical nutrient requiring tight constraint in the endoplasmic reticulum (ER) due to its uniquely challenging biophysical properties. While the mechanisms by which the ER defends against cholesterol insufficiency are well described, it remains unclear how the ER senses and effectively defends against cholesterol excess. Here, we identify the ER-bound transcription factor nuclear factor erythroid 2 related factor-1, Nrf1/Nfe2L1, as a critical mediator of this process. We show that Nrf1 directly binds to and specifically senses cholesterol in the ER through a defined domain and that cholesterol regulates Nrf1 turnover, processing, localization, and activity...

BACKGROUND: Hepatocellular carcinoma (HCC) causes over 800,000 deaths worldwide annually, mainly in low income countries, and incidence is rising rapidly in the developed world with the spread of hepatitis B (HBV) and C (HCV) viruses. Natural Killer (NK) cells protect against viral infections and tumours by killing abnormal cells recognised by Killer-cell Immunoglobulin-like Receptors (KIR). Thus genes and haplotypes encoding these receptors may be important in determining both outcome of initial hepatitis infection and subsequent chronic liver disease and tumour formation...
