Analysis of liver from IQ-motif containing GTPase-activating protein 2 (IQGAP2) KOs at 6- and 24-months of age. IQGAP2 is a member of a multidomain scaffolding protein family that also includes IQGAP1 and IQGAP3. Results provide insight into a potential tumor suppressive role for IQGAP2 in liver.

(Submitter supplied) Whole body knockout mice lacking IQ-motif containing GTPase-activating protein 2 (IQGAP2) develop spontaneous hepatocellular carcinoma (HCC) at the age of 12 months and older (Schmidt et al., 2008). Hepatic transcript expression profiles were obtained for IQGAP2 knockout and wild-type control mice of two age groups, 6- and 24-month-old. Liver samples from 24-month-old IQGAP2 knockout mice were HCC tumors, livers from all other groups were tumor-free. more...

(Submitter supplied) Mouse liver tumors (T) and non tumoral adjacent livers (NT) sorted from mice knock out for Axin1 gene specifically in the hepatocytes . 3 mice of the brother hood non deleted for Axin1 were used as controls (WT) We used microarrays to determine the differential expression between tumoral and non tumoral tissue.

(Submitter supplied) Hepatocellular carcinoma (HCC) affects millions of people worldwide and is a lethal malignancy for which there are no effective therapies. To identify prognostic gene markers for liver cancer, we conducted transcriptome profiling of frozen tissues (tumor and non-tumor) from 300 early-to-advanced stage HCCs plus 40 cirrhotic and 6 normal livers.

(Submitter supplied) Mouse models of hepatocellular carcinoma (HCC) simulate specific subgroups of human HCC. We investigated hepatocarcinogenesis in Mdr2-KO mice, a model of inflammation-associated HCC, using gene expression profiling and immunohistochemical analyses. Gene expression profiling demonstrated that although Mdr2-KO mice differ from other published murine HCC models, they share several important deregulated pathways and many coordinately differentially expressed genes with human HCC datasets. more...

(Submitter supplied) Non-coding microRNAs (miRNAs) mainly regulate the expression of targeted genes by regulating mRNA degradation or repressing their protein translation. MiRNA microarray profiling was then performed on 218 human HCC tumors samples, 10 samples from adjacent cirrhotic non-tumoral tissue, 10 samples from healthy liver and 12 HCC cell lines. In this study we investigated which miRNAs were differentially expressed in HCC compared to cirrhotic non-tumoral tissue and healthy liver.

(Submitter supplied) Serine-threonine kinase receptor-associated protein (STRAP) is upregulated in breast, colorectal and lung cancers, promoting their growth. We identify the upregulation of STRAP in hepatocellular carcinomas. Elevated STRAP endows tumor cells with growth advantage by reprograming a variety of metabolic processes and signaling pathways critical for hepatocellular carcinoma progression. Especially, enhanced Wnt/β-catenin signaling is likely to be a major effector of its tumor-promoting role.

Analysis of Met-deficient hepatocytes treated with HGF for up to 24 hours. HGF/Met signaling controls invasive growth and metastasis in a variety of cancers, including hepatocellular carcinoma. Results identify a Met-dependent gene expression signature that may help elucidate the oncogenic process.

(Submitter supplied) The goal of this study was to identify and analyze differential gene expression between normal liver and tumor tissue responding or not to potential treatments. A second goal was to compare the mouse results with that from analysis of human differential gene expression for normal liver and hepatocellular carcinoma.

(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...
