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...

Doxorubicin in combination with other cytotoxic drugs has clinical advantages. However, doxorubicin-induced cardiotoxicity negatively impacts clinical utility and outcomes. Cardiotoxicity can result from increased oxidative stress or from a local cytochrome P450 mediated increase in 20-hydroxy-5, 8, 11, 14-eicosatetraenoic acid (20-HETE). Oleanolic acid (OA) is a natural pentacyclic triterpenoid with free radical scavenging, cardioprotective, and P450-mediated cyclooxygenase-upregulating properties. We investigated co-delivery of liposomal OA and doxorubicin in a HepG2 model of hepatocellular carcinoma (HCC)...

Numerous studies have demonstrated that microRNAs are very important in cancer development and progression. However, the complex relationship between the size of microRNA delivery systems, cellular uptake, biodistribution and therapeutic efficiency remains unclear. Herein, we have successfully constructed a series of differently-sized microRNA delivery systems, miR-26a-loaded, hyaluronic acid-modified, polyetherimide-conjugated PEGylated gold nanocage ternary nanocomplexes (PPHAuNCs-TNCs), which can be monitored optically by fluorescence and photoacoustic tomography imaging...

Specific RNAs can function as sinks for endogenous miRNAs, known as competing endogenous RNAs (ceRNAs). Here, we confirm a miR-124 mediated ceRNA crosstalk between LAMC1 and CD151 in hepatocellular carcinoma (HCC). miR-124 negatively regulates LAMC1 expression through two miRNA binding sites within its 3' untranslated region (3'UTR) and suppresses migration and invasion of HCC cells through regulating LAMC1. The wild type LAMC1 miRNA response elements (MREs) facilitate expression of CD151, and this regulation is miR-124 dependent...

A growing epidemic of nonalcoholic fatty liver disease (NAFLD) is paralleling the increase in the incidence of obesity and diabetes mellitus in countries that consume a Western diet. As NAFLD can lead to life-threatening conditions such as cirrhosis and hepatocellular carcinoma, an understanding of the factors that trigger its development and pathological progression is needed. Although by definition this disease is not associated with alcohol consumption, exposure to environmental agents that have been linked to other diseases might have a role in the development of NAFLD...

Non-alcoholic fatty liver disease (NAFLD), the most common liver disease, is characterized by accumulation of fat (>5% of the liver tissue), in the absence of alcohol abuse or other chronic liver diseases. It is closely related to the epidemic of obesity, metabolic syndrome or type 2 diabetes mellitus (T2DM). NAFLD can cause liver inflammation and progress to non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis or hepatocellular cancer (HCC). Nevertheless, cardiovascular disease (CVD) is the most common cause of death in NAFLD/NASH patients...

PURPOSE: Polymer-based nanoparticles are used as vectors for cancer drug delivery. The bioactive compounds (quercetin, ellagic acid and gallic acid) are well known to be not only antioxidants but also chemopreventive candidates against various types of cancers. To circumvent the low bioavailability and the short half-life time obstacles, we hypothesized a novel PLGA nano-platform functionalized with CS and PEG to encapsulate these phytochemicals. This encapsulation will protect the compounds from the phagocytic uptake and deliver PLGA-CS-PEG nano-prototype with high biodegradability and biosafety...

Following the introduction of the first laparoscopic liver resection, after ∼25 years, a critical reappraisal seems to be warranted. Liver resection represents the first choice for curing early hepatocellular carcinoma (HCC) allowing a curative chance also in selected patients with intermediate stage tumors. The criteria for liver resectability by laparoscopy remains the same for open surgery, which is oncological criteria (absence of extrahepatic tumor location; completely resectable R0 resection), anatomic (resectability of involved segment with its own blood surely and biliary drainage; absence of vascular invasion of portal or hepatic veins) and technical (possibility to leave in place a residual volume ≥40%)...

Severe alcoholic hepatitis is implicated as a costly, worldwide public health issue with high morbidity and mortality. The one-month survival for severe alcoholic hepatitis is low with mortality rates high as 30%-50%. Abstinence from alcohol is the recommended first-line treatment. Although corticosteroids remain as the current evidence based option for selected patients with discriminant function > 32, improvement of short-term survival rate may be the only benefit. Identification of individuals with risk factors for the development of severe alcoholic hepatitis may provide insight to the diverse clinical spectrum and prognosis of the disease...

Lynn Jeanette Savic, Julius Chapiro, Jean-François Geschwind
In this issue of Radiology, Gade et al ( 1 ) describe a unique mechanism of hepatocellular carcinoma (HCC) cells for surviving ischemia induced by transarterial embolization (TAE)/transarterial chemoembolization (TACE) in a state of cell cycle arrest-a function that may serve as a defensive shield against conventional chemotherapeutic agents. This finding adds to our knowledge and establishes a previously poorly understood mechanism of chemoresistance in HCC. As the Achilles heel in terms of this process, a concurrent upregulation of autophagic flux as an adaptive response to TAE-like ischemia was found by the authors...

Hepatocellular carcinoma is highly refractory cancer which is resistant to conventional chemotherapy and radiotherapy, carrying a dismal prognosis. Although many anticancer drugs have been developed for treating HCC, sorafenib is the only effective treatment, but it only prolongs survival duration for about 3 months. Recently, oncolytic virotherapy has shown promising results in treating HCCs and the effects can be more enhanced by adopting immune modulatory molecules. This review discusses the current status of treating HCC and the effective strategy of oncolytic virus-based immunotherapy for the treatment of HCCs...

BACKGROUND: Cirrhosis increases a patient's risk of developing postoperative liver failure (PLF). Liver stiffness (LS), assessed by two-dimensional shear wave elastography (SWE), indicates liver fibrosis with high accuracy. Whether LS is superior to portal hypertension (PHT) in predicting PLF remains to be studied. METHODS: The study enrolled 280 patients who underwent hepatectomy for hepatocellular carcinoma from July 2015 to July 2016. All patients received preoperative assessments for LS, PHT, and serum markers of liver fibrosis in addition to other clinicopathological tests...

Long Non-coding RNAs (lncRNAs) refer to all non-protein coding transcripts longer than 200 nucleotides. Their critical roles in different biological pathways have been already well established. Altered expression of lncRNAs can be involved in the cancer initiation and/or progression. Since patients with hepatocellular carcinoma (HCC) are usually diagnosed in late stages, developing diagnostic methods seems to be essential. In this study, the expression levels of different lncRNAs were systematically analysed in different genomic and transcriptome datasets...

Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are national and global epidemics. The disease is characterized by a spectrum of liver steatosis (fat deposition), inflammation (in NASH) and fibrosis. NAFLD and specifically NASH can lead to cirrhosis, which carry risks of progression to portal hypertension and hepatocellular carcinoma (HCC). NASH is also associated with higher mortality from cardiovascular causes. Most of the data for NAFLD has been obtained from the perspective of developed nations, although the disease is increasing and threatening to reach epidemic proportions across the world...

In the United States, chronic infection with the hepatitis C virus (HCV) affects an estimated 0.1-2% of the pediatric population, who are consequently at risk for major complications, including cirrhosis, hepatocellular carcinoma, and death. The current standard of treatment for chronic hepatitis C (CHC) in children is pegylated-interferon-alpha (PEG-IFN) in combination with ribavirin. PEG-IFN/ribavirin therapy is approved for children ages 3 and older; however, it is often held from use until adulthood because of its extensive list of potential side effects and high likelihood of causing adverse symptoms...

Background and Aims: Hepatitis C virus (HCV) hepatotropism is associated with intra-peripheral blood mononuclear cell (PBMC) infection that causes post-treatment relapse in RNA seronegative patients. Our understanding of the association of non-viremic hepatic fibrosis with positive anti-HCV IgG antibodies and active hepatocellular damage might be increased by PBMCs screening for intracellular infection. Thus, the goals of this study included evaluation of PBMCs PCR for diagnosing HCV infection, addressing PBMCs plus serum real-time (SRT) PCR benefits over SRT-PCR alone, studying intra-PBMCs distribution of RNA sense and antisense strands, and identifying treatment feasibility in solitary intracellular infection...
