(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) Over expression of PDGF-C in mouse liver resulted in the progression of hepatic fibrosis, steatosis and the development of HCC; this mouse model closely resembles the human HCC that is frequently associated with hepatic fibrosis. Peretinoin (generic name; code, NIK-333), developed by the Kowa Company, (Tokyo, Japan), is an oral acyclic retinoid (ACR) with a vitamin A-like structure that targets the retinoid nuclear receptor. more...

(Submitter supplied) BCAA were administered to atherogenic and high-fat (Ath & HF) diet-induced nonalcoholic steatohepatitis (NASH) model mice and platelet-derived growth factor C transgenic mice (Pdgf-c Tg). Liver histology, tumor incidence, and gene expression profiles were evaluated. BCAA supplementation improved hepatic steatosis, inflammation, fibrosis, and tumors in the NASH mouse model, possibly through the modification of mTORC1 signaling.

(Submitter supplied) Long noncoding RNAs (lncRNAs) play important roles in various biological processes; however, few have been identified that regulate hepatic stellate cells (HSCs) activation and the progression of liver fibrosis. Through a detailed analysis of the expression of lncRNAs in various tissues, we discovered the existence of a liver enriched lncRNA-LFAR1 (lncRNA-Liver Fibrosis Associated RNA1). To identify the roles of lncRNA-LFAR1 in liver fiboris, we systematically analyzed the regulation of mRNAs in primary HSCs infected with two separated lnc-LFAR1-shRNAs by RNA-seq, which revealed a panel of mRNAs that were specifically regulated by lncRNA-LFAR1 in mouse primary HSCs.

To identify the possible roles of lncRNAs in regulating liver fiboris and the potential of lncRNAs as molecular markers for liver fiboris, we systematically analyzed the regulation of lncRNAs and mRNAs in a mouse model of carbon tetrachloride (CCl4)-induced liver fibrogenesis by microarray analysis, which revealed a panel of lncRNAs and mRNAs that were specifically regulated in livers of mice undergoing hepatic fibrosis. more...

(Submitter supplied) Background/Aims: Sept4, a subunit of the septin cytoskeleton specifically expressed in quiescent hepatic stellate cells (HSCs), is downregulated through transdifferentiation to fibrogenic and contractile myofibroblastic cells. Since Sept4−/− mice are prone to liver fibrosis, we examined the unknown molecular network underlying liver fibrosis by probing the association between loss of Sept4 and accelerated transdifferentiation of HSCs. more...

(Submitter supplied) Background & Aims: Rapid induction of beta-PDGF receptor (beta-PDGFR) is a core feature of hepatic stellate cell activation, the hallmark of liver fibrogenesis. However, biological consequences of the induction are not well characterized. We aimed to determine the involvement of beta-PDGFR-mediated molecular pathway activation on hepatic stellate cells in liver injury, fibrogenesis, and carcinogenesis in vivo. more...

(Submitter supplied) Angiocrine signaling by liver sinusoidal endothelial cells (LSEC) regulates liver functions such as liver growth, metabolic maturation, and regeneration. Recently, we identified GATA4 as the master regulator of LSEC specification during development. Here, we studied endothelial GATA4 in the adult liver and in hepatic disease pathogenesis. We generated adult Clec4g-icretg/0xGata4fl/fl (Gata4LSEC KO) mice with deficiency of Gata4 in LSEC. more...

(Submitter supplied) Liver sinusoidal endothelial cells (LSEC) constitute discontinuous, permeable microvessels, with a characteristic program of gene expression that differs significantly from continuous microvascular endothelial cells e.g. in the lung. Gata4 is described as master regulator of LSEC specification during liver development. Here, we sought to analyze the role of endothelial Gata4 in the adult liver. We used microarrays to analyse the program of gene expression in murine whole liver lysates with LSEC-specifig Gata4 deficiency.

LSEC play a pivotal role in liver fibrogenesis in the CDAA dietary model of non-alcoholic steatohepatitis (NASH). We used microarrays to analyse the program of gene expression in murine liver endothelial cells after 10 weeks of CDAA diet.

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) The HGF/c-Met system is an essential inducer of hepatocyte growth and proliferation. Although a fundamental role for the HGF receptor c-Met has been demonstrated in acute liver regeneration its cell specific role in hepatocytes during chronic liver injury and fibrosis progression has not been determined yet. In order to better characterize the role of c-Met in hepatocytes we generated a hepatocyte-specific c-Met knockout mouse (c-Met∆hepa) using the Cre-loxP system and studied its relevance after bile-duct ligation. more...
