(Submitter supplied) Hepatocellular carcinoma (HCC) is the second leading cause of cancer death worldwide, indicating urgent need for novel preventive strategies. Cancer chemoprevention discovery has been challenging due to the absence of tractable and clinically relevant model systems. Here, we developed a simple and robust human liver cell-based system, in which persistent hepatitis C virus (HCV) infection induces a HCC risk signature robustly predicting long-term HCC risk in cirrhotic patients. more...

(Submitter supplied) Abstract: Chronic liver disease and hepatocellular carcinoma (HCC) are life-threatening with limited treatment options. The lack of clinically relevant/tractable experimental models hampers therapeutic discovery. We developed a simple and robust human liver cell-based system modeling a clinical prognostic liver signature (PLS) predicting long-term liver disease progression toward HCC. Using the PLS as a readout, followed by validation in NASH-HCC animal models and patient-derived tumorspheroids, we identified nizatidine, a histamine receptor H2 (HRH2) blocker, for treatment of advanced liver disease and HCC chemoprevention. more...

(Submitter supplied) Hepatocellular carcinoma (HCC) is the second leading cause of cancer death. Curative approaches are limited and chemoprevention is not available. A 186-gene signature in liver tissue predicts HCC risk in cirrhotic patients of various etiologies. However, the drivers of the HCC risk gene signature remain to be fully elucidated. Here, we develop a simple and robust liver cell-based system in which persistent hepatitis B and C virus infection or ethanol exposure induce this signature. more...

(Submitter supplied) Hepatocellular carcinoma (HCC) is one of the leading cause of cancer-related mortality worldwide. Liver cirrhosis is well-established risk factor of HCC development, although prevention of HCC in cirrhosis patients is challenging. By utilizing bioinformatic compound screening based on a clinical HCC-risk-predicitve gene signature, we identified captopril as a potential HCC chemoprevention agent. We tested the drug in rats with diethylnitrosamine (DEN)-induced cirrhosis and HCC, and confirmed its HCC-preventive effect.

(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) Here, we developed a mouse model with long-term chronic (8-12 week) plus single/multiple binge ethanol feeding, which mimicks the drinking patterns of AH patients, who often have a history of chronic drinking plus recent excessive drinking. This model produces severe macrosteatosis, significant inflammation, and mild fibrosis. Moreover, we conducted translational studies by comparing transcriptome data from this clinically relevant in vivo model and human AH biopsy samples, and identified many similar disregulated genes in this animal model and AH samples. more...

(Submitter supplied) Chronic liver injury triggers complications such as liver fibrosis and hepatocellular carcinoma (HCC), which are associated with alterations in distinct signaling pathways. Of particular interest is the interaction between mechanisms controlled by IKKγ/NEMO, the regulatory IKK subunit, and Jnk activation for directing cell death and survival. In the present study, we aimed to define the relevance of Jnk in hepatocyte-specific NEMO knockout mice (NEMOΔhepa), a genetic model of chronic inflammatory liver injury. 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) 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) 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...
