Stable expression and integrated hepatitis B virus genome in a human hepatoma cell line.
HepG2.2.15 cell is a widely used cell model for studying HBV (hepatitis B virus) in vitro. In these cells, the HBV genome is integrated in several sites of HepG2 cellular DNA. These multiple copies may have some influence on the cellular processes. We constructed a new plasmid, pSEH-Flag-HBV, and transfected it into HepG2 cells, and then screened it with hygromycin. We then used ELISA, PC...
متن کاملDevelopment of a Stable Cell Line, Overexpressing Human T-cell Immunoglobulin Mucin 1
Background: Recent researches have demonstrated that human T-cell immunoglobulin mucin 1 (TIM-1) glycoprotein plays important roles in regulation of autoimmune and allergic diseases, as well as in tumor immunity and response to viral infections. Therefore,targeting TIM-1 could be a potential therapeutic approach against such diseases. Objectives: In this study, we aimed to express TIM-1 protein...
متن کاملHepatitis C virus RNA synthesis in a cell-free system isolated from replicon-containing hepatoma cells.
A number of hepatitis C virus (HCV) proteins, including NS5B, the RNA-dependent RNA polymerase, were detected in membrane fractions from Huh7 cells containing autonomously replicating HCV RNA replicons. These membrane fractions were used in a cell-free system for the analysis of HCV RNA replication. Initial characterization revealed a reaction in which the production of replicon RNA increased o...
متن کاملCell clones selected from the Huh7 human hepatoma cell line support efficient replication of a subgenomic GB virus B replicon.
Tamarins (Saguinus species) infected by GB virus B (GBV-B) have recently been proposed as an acceptable surrogate model for hepatitis C virus (HCV) infection. The availability of infectious genomic molecular clones of both viruses will permit chimeric constructs to be tested for viability in animals. Studies in cells with parental and chimeric constructs would also be very useful for both basic...
متن کاملCytotoxicity of Subtoxic AgNP in Human Hepatoma Cell Line (HepG2) after Long-Term Exposure
Background: We aimed at evaluating the toxicity effects of low (subtoxic) concentrations of silver nanoparticles (AgNP, 5-10 nm) in human hepatoblastoma (HepG2) cell line after and during a period of about one month. Methods: XTT and MTT assays were used to draw a dose-response curve IC50 (half maximal inhibitory concentration) value of the AgNP on HepG2 cells was calculated to be 2.75-3.0 mg/l...
