Project description:To identify novel ghost factors regulating the expression of Interferon Stimulated Genes (ISGs), we conducted genome-wide cDNA screening in Huh-7 IFIT-1 Luc cells Huh-7 cells stably expressing IFIT1 luciferase reporter were plated into the wells with pre-spotted cDNA clones from MGS collection (http://mgc.nci.nih.gov/) (reverse transfection). The inducibility of luciferase activity upon the introduction of each cDNA clone was then measure to determine the regulator of IFIT1 expression. Two biological replicates were tested and the averages were taken for measurement.

Project description:mRNA expression profile modified by stable transfection of microRNA mir-517a (MIR517A) in a human hepatocellular carcinoma cell line Huh-7 Keywords: Hepatocellular carcinoma, Expression array, microRNA microRNA mir-517a (MIR517A) was transfected to Huh-7 cells using GFP-expressing lentiviral vector. Infected cells were selected using flow cytometry and subjected to mRNA expression microarray experiment. The profiles were compared to controls cells infected with only GFP protein.
Project description:We performed a BioID experiment in a HEK293 Flp-In T-Rex cell line that contains human GNL3 cDNA integrated at the FRT site tagged with BirA and FLAG under the control of a promoter regulated with doxycycline.
Project description:The gastric adenocarcinoma cell line HGC-27 and colorectal adenocarcinoma cell line HCT-8 cells were grown in Roswell Park Memorial Institute (RPMI) 1640 medium (Hyclone, Logan, UT, USA.). The human hepatocellular carcinoma cell lines HepG2 and Huh-7 were cultured in Dulbecco’s modified Eagle's medium (DMEM) (Hyclone, Logan, UT, USA.).
Project description:Hepatitis C virus (HCV) is a global problem. To better understand HCV infection researchers employ in vitro HCV cell-culture (HCVcc) systems that use Huh-7 derived hepatoma cells that are particularly permissive to HCV infection. A variety of hyper-permissive cells have been subcloned for this purpose. In addition, subclones of Huh-7 which have evolved resistance to HCV are available. However, the mechanisms of susceptibility or resistance to infection among these cells have not been fully determined. In order to elucidate mechanisms by which hepatoma cells are susceptible or resistant to HCV infection we performed genome-wide expression analyses of six Huh-7 derived cell cultures (Huh-7, Huh-7.5.1, Huh-7.5.1c2, R1.09, R1.10 and R2.1) R that have different levels of permissiveness to infection. A great number of genes, representing a wide spectrum of functions are differentially expressed between cells. To focus our investigation, we identify host proteins from HCV replicase complexes, perform gene expression analysis of three HCV infected cells (infected Huh-7, Huh-7.5.1 and Huh-7.5.1c2) and conduct a detailed analysis of differentially expressed host factors by integrating a variety of data sources. Our results demonstrate that changes relating to susceptibility to HCV infection in hepatoma cells are linked to the innate immune response, secreted signal peptides and host factors that have a role in virus entry and replication. This work identifies both known and novel host factors that may influence HCV infection. Our findings build upon current knowledge of the complex interplay between HCV and the host cell, which could aid development of new antiviral strategies. Six Huh-7 derived hepatoma cell types that have different levels of susceptibility to HCV infection in cell culture are used: Huh-7, Huh-7.5.1, Huh-7.5.1c2, R1.09, R1.10 and R2.1. Of these the first three (label starting Huh are susceptible to HCV infection and the latter three (label starting R are resistant to HCV infection. All cell types are derived from Huh-7. Huh-7.5.1 is a subclone of Huh-7.5 that in turn is a subclone of Huh-7. Huh-7.5.1c2 is a subclone of Huh-7.5.1. R1.09 and R1.10 are subclones of R1 that is inturn a sublone of Huh-7.5,1. R2.1 is a subclone of Huh-7.5.1.
Project description:Genome-wide CRISPR screens were performed in Huh-7 hepatoma cell line to identify genes regulating ferroptosis sensitivity. Huh-7 cells were transduced with Human GeCKO library and selected by RSL-3.
Project description:ARID1A, which encodes a component of the SWI/SNF chromatin-remodeling complex, is commonly mutated in ovarian clear cell carcinoma and many other cancer types. We used label-free LC-MS/MS to identify ARID1A-dependent proteome changes in ovarian clear cell carcinoma cell lines. In our first analysis, we compared ARID1A-wildtype ovarian clear cell carcinoma cell line OVCA429 with or without ARID1A CRISPR knockout. In a complementary analysis, we compared ARID1A-mutated ovarian clear cell carcinoma cell line OVISE with or without ARID1A overexpression using a tet-inducible promoter.
