Project description: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
Project description:We analyzed the expression of RNAs in hepatocytes isolated from Apclox/lox livers, after injection of adenovirus Ad5-Cre-GFP and hepatocyte sorting on the basis of GFP signal at day 6, 15 and 21 post-injection. Our aims was to study the transcriptional impact of the beta-catenin during the early steps of liver tumorigenesis.
Project description:Hepatocytes isolated from DILI patient's liver (#2064) were cultured for a long term using irrMEF and EMUKK-05, and comprehensive gene expression was compared between Puromycin-treated and non-treated groups. In addition, comprehensive gene expression analysis of human mature hepatocytes, primary cultured cells, and ips cell-derived hepatocyte-like cells were performed as controls. Two-condition experiment, Proliferating hepatocytes (ProilHH) vs. puromycin-treated ProliHH. Primary human hepatocytes (PHH) and isolated humen mature hepatocytes (MH) and human iPSC-derived hepatocyte-like cells (HLC) as controls.
Project description:We analyzed chromatin opening in hepatocytes isolated from Apclox/loxlivers, after injection of adenovirus Ad5 -Cre-GFP and sorting on the basis of GFP signal at day 6, 15 and 21 post-injection. Our aims was to study the impact of an aberrant beta-catenin activation on chromatin opening in hepatocytes during the early steps of liver tumorigenesis.
Project description:We analyzed chromatin opening in hepatocytes isolated from ApcDeletaHep livers or wt by ATAC-seq. We thus explore how an aberrant activation of beta-catenin signaling modifies chromatin structure in hepatocytes
Project description:Primary Human Hepatocytes (PHH) were exposed daily for 5 days to 15 mM VPA after which DNA was isolated. After terminating the VPA treatment, part of the cells were kept with medium for 3 days in order to investigate the eventual persistence of VPA-induced methylome changes. Identification of methylated regions in the DNA was carried out by the Methylated DNA Immuno-Precipitation - sequencing (MeDIP-seq) method and contains the following steps: fragmentation, library preparation, MeDIP, and sequencing.
