REVIEW
Lauren G Poole, Christine E Dolin, Gavin E Arteel
Alcohol consumption is a common custom worldwide, and the toxic effects of alcohol on several target organs are well-understood. Given the poor prognosis of treating clinically-relevant alcoholic liver disease (ALD) (i.e., alcoholic hepatitis (AH) and cirrhosis), additional research is required to develop more effective therapies. While the stages of ALD have been well-characterized, targeted therapies to prevent or reverse this process in humans are still needed. Better understanding of risk factors and mechanisms underlying disease progression can lead to the development of rational therapies to prevent or reverse ALD in the clinic...

1. Cytochrome P450 (P450) regulators including nuclear receptors and transcription factors have not been fully investigated in cynomolgus macaques, an important species used in drug metabolism studies. In this study, we analyzed seventeen P450 regulators by sequence and phylogenetic analysis, and tissue expression. 2. Gene and genome structures of seventeen P450 regulators were similar to the human orthologs, and the deduced amino acid sequences showed high sequence identities (92-95%) and more closely clustered, with the human orthologs...

Meckel-Gruber syndrome (MKS) is a rare lethal autosomal recessive disorder with typical anomalies including encephalocele, multicystic renal dysplasia, congenital liver fibrosis, and polydactyly. MKS is caused by mutations of genes localized on different chromosomes. Karyotypes of published Meckel-Gruber syndrome cases are without any aberrations. We present a male fetus with meningoencephalocele, multicystic renal dysplasia, congenital liver fibrosis, and other anomalies. Standard cytogenetic examination of cultured fetal skin and muscle fibroblasts showed mosaic trisomy 17...

Anterior diaphragmatic defects with pericardial involvement are extremely rare and diagnostically challenging entities encountered perinatally. While a majority of diaphragmatic defects occur in isolation, others are associated with multiple defects forming a complex of syndromes such as Pentalogy of Cantrell. Liver herniation into the pericardial sac poses a particular challenge and can mimic a pericardial tumor on prenatal ultrasound, yielding a different management course. The following case is an unusual presentation of a 30-week gestation female with an anterior midline diaphragmatic defect with liver herniation mimicking as a pericardial tumor, diagnosed at time of autopsy...

In this study, we want to understand whether crocin could prevent mitochondrial damage caused by As III. For this purpose, we determined different mitochondrial toxicity endpoints caused by As III. We evaluated mitochondrial ROS formation, lipid peroxidation, mitochondrial membrane potential collapse, mitochondrial outer membrane integrity and cytochrome c release. Our results showed that pretreatment with crocin at a concentration of 25 µg/ml significantly (P < 0.001) reduced As III induced mitochondrial ROS formation, lipid peroxidation, mitochondrial membrane potential collapse and mitochondrial swelling...

Xanthohumol, a prenylated flavonoid found in hops (Humulus lupulus L.), exhibits multiple biological activities such as anti-atherosclerosis and hypolipidemic activities. In this study, we aim to investigate the hypocholesterolemic effects and molecular mechanisms of xanthohumol in hepatic cells. We found that xanthohumol (10 and 20 μM) increased the amount of cell-surface low-density lipoprotein receptor (LDLR) from 100.0 ± 2.1% to 115.0±1.3% and 135.2±2.7%, and enhanced the LDL uptake activity from 100...

The cultured hepatic cells in vitro are prone to losing their characteristic morphologies and biological functions. To avoid this problem, a hybrid co-culture system was proposed to elucidate the effect of cellular communication on the phenotype of hepatic cells. A monolayer of endothelial cells (ECs) was co-cultured on the surface of a three-dimensional (3D) scaffold embedded with HepG2 cells. In this hybrid co-culture system, the growth of encapsulated hepatic cells is barely influenced by the co-cultured ECs...

PURPOSE: The prognostic value of the tumor-to-liver uptake ratio (TLR) from 18-fluoro-2-deoxyglucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) in the early stage of colorectal cancer (CRC) is unclear. Notably, some stage IIA CRC patients experience early recurrence even after curative resection and might benefit from neoadjuvant or adjuvant chemotherapy. This study aims to evaluate whether elevated TLR from (18)F-FDG-PET/CT can predict poor prognosis in stage IIA CRC patients undergoing curative resection...

BACKGROUND: Studies of soft tissue composition using computed tomography (CT) scans are often semi-quantitative and based on Hounsfield units (HU) measurements that have not been calibrated with a quantitative CT (QCT) phantom. We describe a study to establish the water (H2O) and dipotassium hydrogen phosphate (K2HPO4) basis set equivalent densities of fat and fat-free liver tissue. With this information liver fat can be accurately measured from any abdominal CT scan calibrated with a suitable phantom...

Hepatocellular carcinoma (HCC) is the commonest primary tumor of the liver and carries a poor prognosis when diagnosed late or left untreated. Treatment relies heavily on the stage of the tumor when diagnosed. Extrahepatic metastasis is known to occur; these are mainly reported via autopsy studies or isolated case reports. Knowledge of extrahepatic metastasis is crucial in order to avoid unnecessary surgery. We report a rare case of a patient at our center, diagnosed to have HCC, who underwent treatment successfully, only to come back with extrahepatic metastasis to the skeletal muscles...

BACKGROUND: Reactive oxygen species- (ROS-) mediated ischemia-reperfusion injury (IRI) detrimentally impacts liver transplantation and resection. 12/15-Lipoxygenase (12/15-LOX), an antagonistic protein of the glutathione peroxidase 4 (GPX4) signaling cascade, was proven to mediate cell death in postischemic cerebral and myocardial tissue. The aim of this study was to investigate the impact of 12/15-LOX inhibition on hepatic IRI. METHODS: Livers of C57BL/6 mice were exposed to 60 minutes of partial warm ischemia and 90 minutes of reperfusion after previous Baicalein administration, an inhibitor of 12/15-LOX...
