BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) is a major leading cause of cancer mortality worldwide. Epigenetic deregulation is a common trait of human HCC. G9s is an important epigenetics regulator. However, its roles in liver carcinogenesis remain to be investigated. METHODS: Gene expressions were determined by RNA-Seq and qRT-PCR. G9a knockdown and knockout cell lines were established by lentiviral-based shRNA and CRISPR/Cas9 gene editing system. Tumor promoting functions of G9a was studied by both in HCC cell lines and nude mice model...

BACKGROUND AND AIMS: Our increasing understanding of hepatocellular carcinoma (HCC) biology holds promise for personalized care, however its translation into clinical practice requires a precise knowledge of its relationship to tumour phenotype. METHODS: We aimed at investigating molecular-phenotypic correlations in a large series of HCC. To this purpose, 343 surgically resected HCC were investigated by pathological review, immunohistochemistry, gene expression profiling and sequencing...

Primary sclerosing cholangitis (PSC) represents a devastating bile duct disease lacking effective medical therapy. 24-norursodeoxycholic acid (norUDCA) is a side chain-shortened C23 homologue of UDCA and has shown potent anti-cholestatic, anti-inflammatory and anti-fibrotic properties in a preclinical PSC mouse model. AIM: To evaluate the safety and efficacy of 3 doses of oral norUDCA (500mg/d, 1000mg/d or 1500 mg/d) compared with placebo in PSC in a RCT including 38centers from 12European countries...

BACKGROUND & AIMS: Hepatic steatosis (HS) seems common in patients infected with human immunodeficiency virus (HIV). However, the relative effect of HIV, as well as hepatitis C virus (HCV) in those co-infected, and the influence of HS on liver fibrosis progression are unclear. METHODS: The LIVEr disease in HIV (LIVEHIV) is a Canadian prospective Cohort using transient elastography and associated controlled attenuation parameter (CAP) to screen for HS and liver fibrosis in unselected HIV-infected adults...

REVIEW
Marina Ruiz de Galarreta, Amaia Lujambio
The recent development of gene editing platforms enables making precise changes in the genome of eukaryotic cells. Programmable nucleases, such as meganucleases, zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeat (CRISPR)-associated nucleases, have revolutionized the way research is conducted as they facilitate the rapid production of mutant or knock-out cellular and animal models. These same genetic tools can potentially be applied to cure or alleviate a variety of diseases, including genetic diseases that lack an efficient therapy...

BACKGROUND & AIMS: Studying hepatitis delta virus (HDV) and developing new treatments is hampered by the limited availability of small animal models. Here a description of a robust mouse model of HDV infection that mimics several important characteristics of the human disease is presented. METHODS: HDV- and HBV-replication competent genomes were delivered to the mouse liver using adeno-associated viruses (AAV) (AAV-HDV and AAV-HBV). Viral load, antigen expression and genomes were quantified at different time points after AAV injection...

REVIEW
Reiner Wiest, Agustin Albillos, Michael Trauner, Jashmohan Bajaj, Rajiv Jalan
The gut is open to the outer environment, harbours the microbiome containing several fold more genetic material than the human genome and produces a myriad of metabolites as well as hormones/peptides. The liver is at the nexus between this vast source of nutrients, toxins and hormones and the remaining human body. Not surprisingly, this liver-gut-axis has hence, been demonstrated in experimental models and in-vitro systems to contribute to the pathogenesis of most liver diseases such as alcoholic and non-alcoholic fatty liver disease (NAFLD), -steatohepatitis (NASH), cholestatic liver diseases, hepatocellular carcinoma, acute-on-chronic liver failure, progression to fibrosis/cirrhosis and complications of cirrhosis...

BACKGROUND & AIMS: Controlled attenuation parameter (CAP) can be performed together with liver stiffness measurement (LSM) by transient elastography and is often used to diagnose fatty liver. We aimed to define the validity criteria of CAP. METHODS: CAP was measured by the M probe prior to liver biopsy in 754 consecutive patients with different liver diseases at 3 centres in Europe and Hong Kong (derivation cohort, n=340; validation cohort, n=414; 101 chronic hepatitis B, 154 chronic hepatitis C, 349 non-alcoholic fatty liver disease, 37 autoimmune hepatitis, 49 cholestatic liver disease, 64 others; 277 F3-4; age 52±14; body mass index 27...

BACKGROUND AND AIMS: Currently, there are no recommendations in guidelines concerning the preferred diameter of stents for transjugular intrahepatic portosystemic shunt (TIPS) owing to the lack of adequate evidence. We therefore evaluated that compared with 10-mm stents, whether 8-mm stents would achieve similar shunt function with less hepatic encephalopathy (HE) and better liver function. METHODS: Cirrhotic patients were randomly assigned to receive TIPS with an 8-mm or 10-mm covered stent to prevent variceal rebleeding...

BACKGROUND & AIMS: Liver inflammation is central to the progression of chronic viral hepatitis to cirrhosis and hepatocellular carcinoma. The magnitude of viral replication and the specific anti-viral immune responses should govern the degree of inflammation, but a direct correlation is not consistently found in chronic viral hepatitis patients. We aim to better define the mechanisms that contribute to chronic liver inflammation. METHODS: Intrahepatic CD14(+) myeloid cells from healthy donors (n=19) and patients with viral-related liver cirrhosis (HBV, HBV/HDV or HCV; n=15) were subjected to detailed phenotypic, molecular and functional characterisation...

BACKGROUND & AIMS: This study aimed to identify preoperative magnetic resonance (MR) imaging biomarkers for predicting microvascular invasion (MVI) and to determine their diagnostic performance and evaluate whether they are associated with early recurrence after surgery for single hepatocellular carcinoma (HCC). METHODS: The study included 197 patients with surgically resected HCC (≤ 5 cm) who underwent preoperative gadoxetic acid-enhanced MR imaging. Significant MR imaging findings for predicting MVI were identified on univariate and multivariate analyses...

PURPOSE: Liver iron accumulates in various chronic liver diseases where it is an independent factor of survival and cancerogenesis. We here tested a novel room-temperature susceptometer (RTS) to noninvasively assess liver iron concentration (LIC). MATERIALS AND METHODS: 264 patients with or without signs of iron overload or liver disease were prospectively enrolled. 35 patients underwent liver biopsy with semiquantitative iron determination (Prussian Blue staining), atomic absorption spectroscopy (AAS, n=33) or MRI (n=15)...
