(Submitter supplied) Hepatocellular carcinomas (HCCs) exhibit a diversity of molecular phenotypes, raising major challenges in clinical management. HCCs detected by surveillance programs at an early stage are candidates for potentially curative therapies (local ablation, resection, or transplantation). In the long term, transplantation provides the lowest recurrence rates. Treatment allocation is based on tumor number, size, vascular invasion, performance status, functional liver reserve, and the prediction of early (<2 years) recurrence, which reflects the intrinsic aggressiveness of the tumor. more...

(Submitter supplied) We analyzed the level of DNA methylation by MeDIPseq in hepatocytes isolated by collagenase perfusion from Apclox/loxlivers, six days after injection of 2mg tamoxifen vs wt hepatocytes. Our aims was to study the impact of the beta-catenin on DNA methylation during the early steps of liver tumorigenesis

(Submitter supplied) We have generated an immune classifier able to identify patients belonging to the immune subclass of HCC. Characteristics of the immune subclass resemble those of patients who most respond to immunotherapy. We performed microarray expression of the tumors of two patients before starting treatment with nivolumab to verify if the immune classifier generated was able to predict response to immunotherapy.

(Submitter supplied) Aberrant expression of LncRNAs might be responsible for the HCC invasion and metastasis. we employed the LncRNAs microarray technology to study the LncRNAs expression profiles at genome-wide in hepatocellular carcinoma (HCC)tissue samples with early recurrence (less than 1 year, with invasion and metastasis out of liver) and late recurrence (longer than 2 years, without invasion and metastasis out of liver), which had different recurrent/metastatic potentials, by using normal liver tissue as control to screen the dysregulated LncRNAs which are potentially involved in the recurrence, invasion and metastasis process of HCC

(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) Background: The presence of vascular invasion (VI) in pathology specimens has been widely described as closely linked to poor outcome in hepatocellular carcinoma (HCC) patients after tumor resection. Previous attempts have been conducted to achieve molecular markers or signatures to predict HCC recurrence in HCC. Here, we aim to develop a diagnostic model combining clinical and genomic variables able to detect the presence of VI prior to surgery and link it to survival estimation. more...

(Submitter supplied) To investigate mechanisms by which activated β-catenin signaling promotes liver tumor formation and to identify potential therapeutics for these cancers, we generated transgenic zebrafish expressing hepatocyte-specific activated β-catenin (Tg(fabp10a:pt-β-cat) zebrafish. As adults, these animals show increased liver size, decreased survival, and histologic abnormalities similar to human HCC. To further characterize our model, we used microarray analysis to compare gene expression in Tg(fabp10a:pt-β-cat) zebrafish livers to that of non-transgenic control sibling livers.

(Submitter supplied) Transgenic PiZ mice have been genetically engineered to express ATZ and have been a valuable experimental model for liver disease due to AAT polymerization. ATZ accumulates in these mice within the ER of hepatocytes in a nearly identical manner to livers of affected patients. MiRNAs play a key role in a wide range of biological processes and regulate gene expression mainly at the translational level. more...
