(Submitter supplied) The scope of this project is to study, using state-of-the-art systems biology approaches integrating the changes in metabolomics, lipidomics and transcriptomics, changes in hepatocytes' metabolism occurring in human HCC. We focused on altered metabolic pathways including lipogenesis, fatty acid desaturation, and generation of phosphatidylcholine (PC) occurring in HCC vs. paired HCC-free tissue.

(Submitter supplied) The homologous E3 ubiquitin ligases RNF43/ZNRF3 negatively regulate WNT signalling activation. Recently, both genes have been found mutated in several types of cancers. Specifically, loss-of-function mutations result in adenoma formation in mouse small intestine. However, their role in liver pathology and cancer has not been explored yet. Here, we describe that hepatocyte-specific deletion of Rnf43/Znrf3 results in altered lipid metabolism and steatohepatitis, in the absence of exogenous dietary fat supplementation, with a remarkable increase in unsaturated lipids. more...

(Submitter supplied) Hepatocellular carcinoma (HCC) generally arises in chronically inflamed liver and is thought to originate from regenerating liver cells that acquired genetic alterations. Both hepatocytes and ductular progenitor cells (DPCs) contribute to liver regeneration and are candidate cellular origins of HCCs. In the current study, we used lineage-tracing analysis to show that Epcam-expressing DPCs give rise to HCCs in inflamed liver. more...

(Submitter supplied) Hepatocellular carcinoma (HCC) represents a major health problem as it afflicts an increasing number of patients worldwide. Albeit most of the risk factors for HCC are known, this is a deadly syndrome with a life expectancy at the time of diagnosis of less than 1 year. Definition of the molecular principles governing the neoplastic transformation of the liver is an urgent need to facilitate the clinical management of patients, based on innovative methods to detect the disease in its early stages and on more efficient therapies. more...

(Submitter supplied) Here we used RNA-Seq to unravel the gene expression patterns and related signaling pathways that might be responsible for the observed changes in the lipidome upon GDF11 treatment of hepatocellular carcinoma cells (HCC), HepG2. RNA-seq analysis was performed after 24h of GDF11 (100ng/ml) treatment to investigate its involvement in lipid metabolism. Genes exhibiting absolute fold-change values >2 and p-values <0.05 were considered differentially expressed between contrasts and statistical differences in gene expression were assessed by the ANOVA test. more...

(Submitter supplied) Transforming growth factor beta-activated kinase1 (TAK1) encoded by the gene MAP3K7 regulates multiple important downstream effectors involved in immune response, cell death and carcinogenesis. Hepatocyte-specific deletion of TAK1 in Tak1_Hep mice promotes liver fibrosis and hepatocellular carcinoma (HCC) formation. Here, we report that genetic inactivation of RIPK1 kinase using kinase dead knock-in D138N mutation in Tak1_Hep mice inhibits the expression of liver tumor biomarkers, liver fibrosis and HCC formation. more...

(Submitter supplied) Liver cirrhosis is a strong risk factor for the development of hepatocellular carcinoma (HCC), yet the mechanisms by which cirrhosis predisposes patients to tumorigenesis are not well understood. Transgenic mice expressing platelet-derived growth factor C (Pdgf-c) under the control of the albumin promoter provide a unique animal model that mimics the step-wise disease progression in humans from fibrosis to HCC. more...

Analysis of liver stroma from 8.8-week-old PDGF-C transgenics wherein PDGF-C is ectopically expressed in hepatocytes. The transgenics develop progressive liver fibrosis with a high incidence of HCC. Results provide insight into PDGF-C-driven molecular changes in liver stroma contributing to HCC.

(Submitter supplied) Liver cancer is a common cause of cancer death, with a male-predominant incidence due, in part, to increased estrogen levels in cirrhotic patients. It is unknown, however, how estrogen is sensed to influence this process. Here, we show that estrogen activates the G protein-coupled estrogen receptor 1 (GPER1), expressed in hepatocytes, to enhancing hepatocyte size, cell cycle progression and cell proliferation, thereby increasing liver growth in zebrafish larvae and adults. more...

(Submitter supplied) NF-κB has a crucial tumor-suppression role in chemical hepatocarcinogenesis (HCC) by preventing hepatocyte apoptosis-induced compensatory proliferation. However, NF-κB is typically activated in chemical HCC animal models and in ~40% HCC patients, in which its role in tumor progression is largely not known. Here we report that transcription factor Miz1 limits tumor-promoting function of NF-κB independently of its transcriptional activity in chemical HCC. more...

(Submitter supplied) Hepatocellular carcinoma (HCC) is a fatal malignancy with a dismal prognosis. The recent advances in genomics and transcriptomics have led to large volumes of molecular data for HCC, providing an unprecedented opportunity to translate these data into more effective therapeutics. By creating HCC gene expression signatures and comparing with drug response signatures from multiple datasets, we identified four antihelminthics (from over 1000 FDA-approved drugs) that can reverse the HCC disease gene expression. more...

(Submitter supplied) Purpose: To study the effects of high-fat diet feeding in mouse liver tissues with and without the hepatocellular carcinoma-inducing carcinogen DEN. Here, we used RNA sequencing to identify gene expression patterns associated with high-fat diet feeding. Methods: C57BL/6N mice were injected at 2-weeks of age with vehicle control (PBS) or DEN. At 6 weeks, mice were randomized to control diet, or 60% high-fat diet. more...

(Submitter supplied) We recently described the phenotype of HepG2 and Huh-7, hepatocellular carcinoma cells, knocked down for histone variant macroH2A1. Both cell lines acquire a cancer stem cell phenotype (Lo Re O et al., Hepatology 2017, PMID: 28913935; Lo Re O et al., Epigenetics 2018, PMID: 30165787). We found that short hairpin RNA-mediated macroH2A1 knockdown induced acquisition of CSC-like features, including the growth of significantly larger and less differentiated tumors when injected into nude mice. more...
