MiRNA expression data in Huh-7 cell line transfected with HBeAg-expression vector

ABSTRACT: The HBeAg is a well-documented risk factor for HCC in epidemiological studies. The biological role of HBeAg in HBV-related HCC remains poorly understood. The HBeAg-mediated differential expression of host miRNAs We used miRNA microarray chips to assess the host cellular miRNA expression profile in response to HBeAg expression in Huh7 cells

Gene expression data in Huh-7 cell line transfected with HBeAg-expression vector

Project description:The presence of HBeAg has been linked to an increased risk of HBV-realted HCC. However, the biological role of HBeAg in modulating host gene expression is poorly understood. Therefore, we performed a cDNA microarray in response to presence of HBeAg in Huh-7 cells. We used human primeview gene expression microarray chips to assess the host cellular mRNA expression profile in response to HBeAg in Huh7 cells

Huh-7-Mock and Huh-7-HBV

Project description:The expression profiling of HBV-transfected Huh-7 cells and control cells. Hepatocellular carcinoma (HCC) is one of major malignant disease worldwide, and patients with chronic hepatitis B virus (HBV) infection have a high risk of developing HCC. Via microarray gene expression analysis, we detected the gene alteration in HBV transfected hepatoma cells.

Characterization of Hepatitis B Virus Transcripts in Chronically HBV-infected Chimpanzees and Patients Treated with ARC-520 siRNA Demonstrates Transcriptional Silencing of cccDNA

Project description:Full-length hepatitis B virus (HBV) transcripts of chimpanzees and patients treated with multidose (MD) HBV siRNA ARC-520 and entecavir (ETV) were characterized by single-molecule real-time (SMRT) sequencing, identifying multiple types of transcripts with the potential to encode HBx, HBsAg, HBeAg, core, and polymerase, as well as transcripts likely to be derived from dimers of dslDNA, and these differed between HBeAg-positive (HBeAg+) and HBeAg-negative (HBeAg−) individuals. HBV transcripts from the last follow-up ~30 months post-ARC-520 treatment were categorized from one HBeAg+ (one of two previously highly viremic patients that became HBeAg− upon treatment and had greatly reduced cccDNA products) and four HBeAg− patients. The previously HBeAg+ patient received a biopsy that revealed that he had 3.4 copies/cell cccDNA (two to three orders of magnitude more cccDNA than HBeAg− chimpanzees) but expressed primarily truncated X and HBsAg from iDNA, like two patients that were HBeAg− at the start of the study and had one copy/cell cccDNA. No HBV transcripts were detected in two other HBeAg− patients that had ~0.3 copies/cell cccDNA, one of which had seroconverted for HBsAg. The paucity of cccDNA-derived transcripts in the presence of high cccDNA demonstrates the transcriptional silencing of HBV following MD siRNA treatment with ETV.

Huh-7 exosomes and HBV

Project description:Hepatitis B virus (HBV) infection could cause hepatitis, liver cirrhosis and hepatocellular carcinoma. HBV-mediated pathogenesis is only partially understood, but X protein (HBx) reportedly possesses oncogenic potential. Exosomes are small membrane vesicles with diverse functions released by various cells including hepatocytes, and HBV harnesses cellular exosome biogenesis and export machineries for virion morphogenesis and secretion. Therefore, HBV infection might cause changes in exosome contents with functional implications for both virus and host. In this project, exosome protein content changes induced by HBV and HBx were quantitatively analyzed by SILAC/LC-MS/MS. Exosomes prepared from SILAC-labeled hepatoma cell line Huh-7 transfected with HBx, wildtype or HBx-null HBV replicon plasmids were analyzed by LC-MS/MS.

Expression data from HepG2-NTCP and Huh-106 cell lines

Project description:Microarray data to compare the gene expression in HepG2-NTCP and Huh-106 cell lines Knowledge of HBV virus-host interactions is still limited. Here, we performed a genome-wide gain-of-function screen using weakly permissive Huh-106 cells to uncover novel HBV host factors.

Differential miRNA expression profiles betweenHBV-related HCC tumor versus non-tumor liver tissue

Project description:miRNA played an important role in the process of carcinogenesis in HBV related hepatocellular carcinoma. Therefore, we performed miRNA microarray to evaluate the miRNAs that expressed differentially between HCC tumor versus non-tumor liver tissues. RNA was extracted from snap fresh tissue collected from resected HCC tumor and adjacent non-tumor liver tissues. All HCC tumors were HBV-associated HCC.

HBV remodels PP2A complexes to rewire kinase signaling in hepatocellular carcinoma

Project description:Hepatitis B virus (HBV) infection promotes liver cancer initiation by inducing inflammation and cellular stress, but its impact in established tumors is not well understood. We used affinity purification mass spectrometry to comprehensively map a network of 145 physical interactions between HBV and human proteins in hepatocellular carcinoma (HCC). A subset of the host factors targeted by HBV proteins are preferentially mutated in non-HB¬V-associated HCC suggesting that their interaction with HBV influences HCC biology. These include proteins involved in mRNA splicing, mitogenic signaling and DNA repair, with the latter set interacting with the HBV oncoprotein X (HBx). We show that HBx remodels the PP2A phosphatase complex by excluding striatin regulatory subunits from the PP2A holoenzyme. We find that HBx effects on PP2A cause Hippo kinase activation, particularly in cells with high striatin levels. In parallel, HBx activates mTOR complex 2 (mTORC2) to prevent YAP degradation. mTORC2 effects on YAP can be observed in human HCC specimens and mouse HCC models and can be targeted with mTOR kinase inhibitors. Thus, HBV interaction with host proteins rewires HCC signaling rather than directly activating mitogenic pathways. These findings provide a new paradigm for the cellular effects of a tumor promoting virus and support a model where HBV may have therapeutic actionable effects on HCC biology.
