BACKGROUND & AIMS: Little is known about the association between non-alcoholic fatty liver disease (NAFLD) and cancer development. This study investigated the cancer incidence rates in NAFLD and analysed the association between NAFLD and cancer development. METHODS: This historical cohort study included subjects who were followed up for >1 year after having a heath checkup at a tertiary hospital in Korea from September 1, 2004 to December 31, 2005. NAFLD was diagnosed by ultrasonographic detection of hepatic steatosis in the absence of other known liver disease, including alcoholic or viral hepatitis...

Emerging studies have suggested that the Hippo pathway is involved in the tumorigenesis of hepatocellular carcinoma (HCC). However, the key regulator of the Hippo pathway in liver tumor metabolic reprogramming remains elusive. Here, we provide evidence to support that high mobility group box 1 (HMGB1), a chromosomal protein, plays a role in the regulation of the Hippo pathway during liver tumorigenesis. Cre/loxP recombination-mediated HMGB1 depletion in hepatocytes blocks diethylnitrosamine-induced liver cancer initiation in mice, whereas shRNA-mediated gene silencing of HMGB1 inhibits HCC cell proliferation...

Two new unusual dimeric selaginellins, diselaginellins A and B (1 and 2), along with two known derivatives, selaginellin (3) and selaginellin B (4), were isolated from Selaginella pulvinata. Their structures were elucidated by extensive NMR and high-resolution ESIMS data analysis. Compound 2 displayed apoptosis-inducing and antimetastatic activities against the human hepatocellular carcinoma cell line SMMC-7721. A microarray analysis revealed that genes related to metabolism, angiogenesis, and metastasis were altered by 2...

Hepatocellular carcinoma (HCC) causes death mainly by disseminated metastasis progression from the organ being confined. Different metastatic stages are closely related to cellular metabolic profiles. Normal hepatocyte and HepG2 cell line from low metastatic HCC were studied by NMR-based metabolomic techniques. Multivariate and univariate statistical analyses were utilized to identify characteristic metabolites from cells and cultured media. Elevated levels of acetate, creatine, isoleucine, leucine, and phenylalanine were observed in HepG2 cells, suggesting more active in gathering nutrient components along with altered amino acid metabolisms and enhanced lipid metabolism...

Tris(2-chloroethyl) phosphate (TCEP) is a pervasive flame retardant that has been identified as a chemical of concern given its health effects and therefore its use has since been tightly regulated. Tris(2-chloroisopropyl) phosphate (TCIPP), an analogue of TCEP, is believed to be its replacement. However, compared to TCEP, little is known of the toxicological impacts of TCIPP. We used RNA sequencing as unbiased and sensitive tool to identify and compare effects on a transcriptome level of TCEP and TCIPP in the human hepatocellular carcinoma cell line, HepG2...

BACKGROUND: Metabolic syndrome (MetS) is a group of clinicopathological manifestations. The outcome of liver surgery in metabolic syndrome-related hepatocellular carcinoma (MetS-HCC) still needs to be evaluated. We aim to clarify the outcomes following liver resection in patients with MetS-HCC compared those with hepatitis B virus-related HCC (HBV-HCC). METHODS: All the consecutive patients undergoing hepatectomy for HCC between January 2009 and December 2012 were retrospectively considered...

The nuclear protein constitutive active/androstane receptor (CAR or NR1I3) regulates several liver functions such as drug and energy metabolism and cell growth or death, which are often involved in the development of diseases such as diabetes and hepatocellular carcinoma. CAR undergoes a conversion from inactive homodimers to active heterodimers with retinoid X receptor alpha (RXRα), and phosphorylation of the DNA-binding domain (DBD) at Thr-38 in CAR regulates this conversion. Here, we uncovered the molecular mechanism by which this phosphorylation regulates the intramolecular interaction between CARs DBD and ligand-binding domain (LBD), enabling the homodimer-heterodimer conversion...

Hepatits B virus (HBV) infection is a prevalent infectious disease with serious outcomes like chronic and acute hepatitis, cirrhosis and hepatocellular carcinoma. However, the metabolic alteration by HBV is rarely taken into concerns. With the high prevalence of alcohol consumption and chronic HBV infection, their overlap is assumed as an increasing latent hazard although without exact calculation, moreover, the impact of chronic alcoholic consumption combined with HBV on cholesterol metabolism is unknown. Six-week-old male FVB/Ncrl mice were hydrodynamically injected with a pGEM-4Z-1...

REVIEW
Omar Massoud, Michael Charlton
Although hepatocellular carcinoma (HCC) is more common in the setting of cirrhosis, there is increasing evidence that it can develop in the setting of noncirrhotic nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH) and that steatosis alone can promote carcinogenesis. In addition, obesity, diabetes, and metabolic syndrome are recognized risks for the development of HCC. A better understanding of the mechanisms involved in the development of NAFLD/NASH-related HCC will allow the discovery of new targets for therapeutic and preventive intervention...

Christina C Lindenmeyer, Arthur J McCullough
Nonalcoholic fatty liver disease (NAFLD) is a major cause of chronic liver disease worldwide, and its clinical and economic burden will continue to grow with parallel increases in rates of obesity, diabetes, and the metabolic syndrome. Evolving understanding of the natural history of NAFLD suggests that these patients are at risk for disease progression to steatohepatitis, fibrosis, and cirrhosis. Recent studies also suggest that these patients are at elevated risk for cardiovascular-, malignancy-, and liver-related morbidity and mortality, although their risk for progression, decompensation, and hepatocellular carcinoma may be less than that of patients with alternative causes of chronic liver disease...

Pyruvate kinase M2 (PKM2), a key protein in glucose and lipid metabolism, has been reported to be related to carcinogenesis in various malignancies. However, its roles in hepatocellular carcinoma with cirrhotic liver (CL) and hepatocellular carcinoma with non-cirrhoticliver (NCL) haves not been investigated. In our study western bloting, qRT-PCR and immunohistochemistry were performed to evaluate the clinical significance of PKM2 protein expression in CL and NCL. The results revealed that PKM2 protein expression was significantly higher in HCC tissues than in their adjacent non-tumour tissues...

The substantial rise in the prevalence of nonalcoholic steatohepatitis (NASH), an advanced form of nonalcoholic fatty liver disease, and the strong association between NASH and the development of hepatocellular carcinoma indicate the urgent need for a better understanding of the underlying mechanisms. In the present study, by using the Stelic animal model of NASH and NASH-derived liver carcinogenesis, we investigated the role of the folate-dependent 1-carbon metabolism in the pathogenesis of NASH. We demonstrated that advanced NASH and NASH-related liver carcinogenesis are characterized by a significant dysregulation of 1-carbon homeostasis, with diminished expression of key 1-carbon metabolism genes, especially a marked inhibition of the S-adenosylhomocysteine hydrolase (Ahcy) gene and an increased level of S-adenosyl-l-homocysteine (SAH)...

Host cells harbor various intrinsic mechanisms to restrict viral infections as a first line of antiviral defense. Viruses have evolved various countermeasures against these antiviral mechanisms. Here we show that N-Myc Downstream-Reguated Gene 1 (NDRG1) limits productive HCV infection by inhibiting viral assembly. Interestingly, HCV infection down-regulates NDRG1 protein and mRNA expression. Loss of NDRG1 increases the size and number of lipid droplets, which are the sites of HCV assembly. HCV suppresses NDRG1 expression by up-regulating MYC, which directly inhibits the transcription of NDRG1 Up-regulation of MYC also leads to reduced expression of NDRG1-specific kinase SGK1, resulting in markedly diminished phosphorylation of NDRG1...

Currently, molecular markers are not used whilst determining the prognosis and treatment strategy for patients with hepatocellular carcinoma (HCC). Here, we proposed that the identification of common pro-oncogenic pathways in primary tumors (PT), and adjacent non-malignant tissues (AT), that typically used to predict HCC patient risks may result in HCC biomarker discovery. We examined the genome-wide mRNA expression profiles of paired PT and AT samples from 321 HCC patients. The workflow integrated differentially expressed gene selection, gene ontology enrichment, computational classification, survival predictions, image analysis and experimental validation methods...

C-acetate uptake could be increased in physiologic or inflammatory conditions without evidence of cancer. We report a hepatocellular carcinoma patient with sorafenib-induced metabolic acidosis, who showed increased hepatic uptake of C-acetate. C-acetate PET/CT might be a potentially useful surrogate marker to monitor these adverse effects via the changes in C-acetate uptake patterns from before to after drug withdrawal.

Whether non-alcoholic fatty liver disease (NAFLD) precedes insulin resistance (IR) or IR preludes/causes NAFLD has been long debated. Recent studies have shown that there are two phenotypes of NAFLD, 'genetic' vs 'metabolic' NAFLD. The former patients are more at risk of hepatocellular carcinoma and chronic liver disease the latter are more IR and at increased risk of type 2 diabetes (T2D). Even if they are not yet diabetics, from a metabolic point of view having NAFLD is equivalent to T2D with reduced peripheral glucose disposal and impaired suppression of hepatic glucose production, but without fasting hyperglycaemia...

The American Association for the Study of Liver Diseases (AASLD) updated and published the Practice Guidance for the Diagnosis and Management of Nonalcoholic Fatty Liver Disease (NAFLD) in July 2017, which provides recommendations for the accurate diagnosis, treatment, and effective prevention of NAFLD. Related metabolic diseases should be considered during the initial evaluation of patients suspected of NAFLD. Noninvasive diagnostic techniques including transient elastography, magnetic resonance elastography, and serum biochemical models should be used to evaluate the development and progression of liver fibrosis in patients with NAFLD...

Deleted in Breast Cancer 1 (DBC1) is a regulatory protein involved in cell metabolism and cancer progression. Nevertheless, the expression and prognostic values of DBC1 in hepatocellular carcinoma (HCC) are still not well understood. The following study investigated the clinical significance and biological function of DBC1 in HCC. Briefly, overexpression of DBC1 at transcriptional and translational levels in human HCC tissues compared to adjacent normal tissues was observed using quantitative real-time polymerase chain reaction (qRT-PCR), western blot (WB) and immunohistochemistry (IHC) approach...

Hepatocellular carcinoma (HCC) is a frequent neoplasia and a leading cause of inflammation-related cancer mortality. Despite most HCC arise from persistent inflammatory conditions; pathways linking chronic inflammation to cancer development are still incompletely elucidated. We dissected the role of adaptive immunity in the Mdr2-/- mouse, a model of inflammation-associated cancer, in which ablation of adaptive immunity has been induced genetically (Rag2-/-Mdr2-/- and μMt-Mdr2-/- mice) or with in vivo treatments using lymphocyte-specific depleting antibodies (anti-CD20 or anti-CD4/CD8)...
