Right hepatectomy is a standard anatomical procedure used worldwide, and consists of two important steps: access to the portal pedicle at the hepatic hilus and approach through the right hepatic vein. With interest in the early work in the field of right hepatectomy, we searched for official documents, published not only in English but also non-English languages for insights on the history of the great work conducted by pioneer liver surgeons in the East and West. To discuss anatomical right hepatectomy, it is important to consider several issues, including liver anatomy, other anatomical liver resection procedures, control of vascular in-flow and out-flow, operative procedures or approaches, preoperative management and other related issues...

NAFLD is a spectrum comprised of isolated steatosis, NASH, advanced fibrosis, and cirrhosis. The majority of NAFLD subjects do not have NASH and don't carry a significant risk for adverse outcomes (cirrhosis and mortality). Globally, the prevalence of NAFLD is approximately 25%. In Asia, a gradient of high prevalence rates to low rates are noted from urban to rural areas. Given the prevalence of NAFLD, the clinical and economic burden of NAFLD and NASH can be substantial. With increasing recognition as an important liver disease, the diagnosis of NASH still requires a liver biopsy which is suboptimal...

Under current guidelines hepatitis C virus (HCV)-positive livers are not transplanted into HCV-negative recipients because of adverse post-transplant outcomes associated with allograft HCV infection. However, HCV can now be cured post liver transplant (LT) using direct-acting antivirals (DAAs) with >90% success; therefore, HCV-negative patients on the liver transplant (LT) waiting list may benefit from accepting HCV-positive organs with preemptive treatment. Our objective was to evaluate if and in which HCV-negative patients the potential benefit of accepting an HCV-positive (i...

Liver tissue engineering has emerged as a promising approach in organ transplantation, but has been hampered by the lack of a reliable and readily available cell source. Induced pluripotent cells (hiPSC) have been highlighted a desirable source, due to their differentiation potential, ability to self-renew and the possibility of making patient specific cells. We developed a decellularization protocol that efficiently removes cellular material, while retaining extracellular matrix components. Subsequently, hiPSC were differentiated on the decellularized human liver matrix (hDLM) scaffolds using an established hepatic differentiation protocol...

BACKGROUND: Hepatoblastoma is the most common primary hepatic malignancy in children. We have recently noticed an increased incidence of unsuspected fractures in children with newly diagnosed hepatoblastoma. This association has been suggested in the past, but the incidence and pathophysiology remain uncertain. OBJECTIVE: To define the incidence and imaging features of fractures in children with newly diagnosed hepatoblastoma. MATERIALS AND METHODS: We searched the oncology database and the radiology picture archiving and communication system of our large tertiary care children's hospital between January 2000 and August 2013 for all patients who presented to our institution with newly diagnosed hepatoblastoma...

Growth differentiation factor 15 (GDF15) has recently been shown to have an important role in the regulation of mitochondrial function and in the pathogenesis of complex human diseases. Nevertheless, the role of GDF15 in alcohol-induced or fibrotic liver diseases has yet to be determined. In this study, we demonstrate that alcohol- or carbon tetrachloride (CCl4)-mediated hepatic GDF15 production ameliorates liver inflammation and fibrosis. Alcohol directly enhanced GDF15 expression in primary hepatocytes, which led to increased oxygen consumption...

A longitudinal molecular model of the development and progression of nonalcoholic fatty liver disease (NAFLD) over time is lacking. We have recently validated a high fat/sugar water-induced animal (an isogenic strain of C57BL/6 J:129S1/SvImJ mice) model of NAFLD that closely mimics most aspects of human disease. The hepatic transcriptome of such mice with fatty liver (8 weeks), steatohepatitis with early fibrosis (16-24 weeks) and advanced fibrosis (52 weeks) after initiation of the diet was evaluated and compared to mice on chow diet...

In patients with CKD, not only renal but also, nonrenal clearance of drugs is altered. Uremic toxins could modify the expression and/or activity of drug transporters in the liver. We tested whether the uremic toxin indoxyl sulfate (IS), an endogenous ligand of the transcription factor aryl hydrocarbon receptor, could change the expression of the following liver transporters involved in drug clearance: SLC10A1, SLC22A1, SLC22A7, SLC47A1, SLCO1B1, SLCO1B3, SLCO2B1, ABCB1, ABCB11, ABCC2, ABCC3, ABCC4, ABCC6, and ABCG2 We showed that IS increases the expression and activity of the efflux transporter P-glycoprotein (P-gp) encoded by ABCB1 in human hepatoma cells (HepG2) without modifying the expression of the other transporters...

Though calorically equivalent to glucose, fructose appears to be more lipogenic, leading to dyslipidemia, fatty liver disease, cardiovascular disease, and diabetes. To better understand how fructose induces lipogenesis, we compared the effects of fructose and glucose on the mTORC1 signaling node, a central regulator of lipogenesis. We found that fructose acutely and transiently suppressed mTORC1 signaling in vitro and in vivo. The constitutive activation of mTORC1 reduced hepatic lipogenic gene expression and produced hypotriglyceridemia after one week of fructose feeding...

Recently, Korean traditional fermented soybean paste, called Doenjang, has attracted attention for its protective effect against diet-related chronic diseases such as obesity and type 2 diabetes. Long-term fermented soybean pastes (LFSPs) are made by fermentation with naturally-occurring microorganisms for several months, whereas short-term fermented soybean pastes (SFSPs) are produced by shorter-time fermentation inoculated with a starter culture. Here, we demonstrate that administration of LFSP, but not SFSP, protects high-fat diet (HFD)-fed obese mice against non-alcohol fatty liver disease (NAFLD) and insulin resistance...

p73 is a member of the p53 family of transcription factors and, like p53, plays a role as a tumor suppressor. p73 is involved in development, proliferation, apoptosis and metastasis. However, the precise molecular mechanisms underlying its function in inhibiting metastasis remain largely unknown. Here, we show that induction of TAp73 decreased invasion and migration activity of colorectal cancer cells, whereas knockdown of TAp73 led to increased invasion and migration activity. KAI1 was identified as a transcriptional target of TAp73 and its expression is indispensable for TAp73-mediated inhibition of cell invasion and migration...

Pioglitazone (Piog) activates peroxisome proliferator activated receptor-γ (PPARγ) and is widely used in clinic for the treatment of diabetes mellitus. PPARγ in various tissues has the essential regulatory role of multiple metabolic function, suggest that PPARγ signaling may contribute to aging processes. However, little is known about the consequences of Piog on aging in aged animal models. We used apolipoprotein E deficient (apoE-/-) mice model to evaluate the effects of Piog on aging-related disorders...

BACKGROUND AND AIMS: Frail patients with low MELD scores may be underprioritised. Low skeletal muscle mass (i.e. sarcopenia) has been identified as risk factor for waiting list mortality and a recent study proposed to incorporate sarcopenia in the MELD score (i.e. MELD-Sarcopenia score). We aimed to investigate the association between sarcopenia and waiting list mortality, and to validate the MELD-Sarcopenia score (i.e. MELD+10.35∗Sarcopenia). METHODS: We identified consecutive patients with cirrhosis listed for liver transplantation in the Eurotransplant registry between 2007-2014 and measured skeletal muscle mass on computed tomography (CT)...

Liver fibrosis is the most common final outcome for chronic liver diseases. The complex pathogenesis includes hepatic parenchymal damage as a result of a persistent noxe, activation and recruitment of immune cells, activation of hepatic stellate cells, and the synthesis of fibrotic extracellular matrix (ECM) components leading to scar formation. Clinical studies and animal models demonstrated that fibrosis can be reversible. In this regard matrix metalloproteinases (MMPs) have been focused as therapeutic targets due to their ability to modulate tissue turnover during fibrogenesis as well as regeneration and, of special interest, due to their influence on cellular behavior like proliferation, gene expression, and apoptosis that, in turn, impact fibrosis and regeneration...

Non-alcoholic fatty liver disease (NAFLD) and diabetes are severe public health issues worldwide. The Family with sequence similarity 3 (FAM3) gene family consists of four members designated as FAM3A, FAM3B, FAM3C and FAM3D, respectively. Recently, there had been increasing evidence that FAM3A, FAM3B and FAM3C are important regulators of glucose and lipid metabolism. FAM3A expression is reduced in the livers of diabetic rodents and NAFLD patients. Hepatic FAM3A restoration activates ATP-P2 receptor-Akt and AMPK pathways to attenuate steatosis and hyperglycemia in obese diabetic mice...

Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are among the most serious health conditions affecting about 600 million people worldwide leading to a number of severe liver diseases. Due to the lack of warning signs or mild symptoms during the early stage of the infection, a molecular signature associated with disease progression would be useful. Based on our recent paper where candidate biomarkers were determined through topological and modularity analysis of protein interaction networks (PINs), this study was focused on the evaluation of MIF, TNFRSF1A, FAS and TMSB4X as diagnostic biomarkers in chronic HBV and HCV infections...
