Gene expression in Histone H1 variant deletion chicken DT40 mutant cell

ABSTRACT: There are six histone H1 variant in chicken. 01H1/02H1/03H1/.10H1/H1L and H1R. In those variant we forcused on H1L and H1R those molecule were most similar H1 among six H1 variants. we established linker histone H1L and H1R deleted mutant in chicken B-cell derived DT40 cell and assay gene expression in normal condition in those mutant cells. The detail charactalization of those mutant cell was published in Takami et al., BBRC 268, 501-508 (2000) and Hashimoto et al., DNA repair (2007) Keywords: gene expression array-based, count

Transcription profiling of chicken histone H1 variant deletion DT40 mutant cell

Project description:There are six histone H1 variant in chicken. 01H1/02H1/03H1/.10H1/H1L and H1R. In those variant we forcused on H1L and H1R those molecule were most similar H1 among six H1 variants. we established linker histone H1L and H1R deleted mutant in chicken B-cell derived DT40 cell and assay gene expression in normal condition in those mutant cells. The detail charactalization of those mutant cell was published in Takami et al., BBRC 268, 501-508 (2000) and Hashimoto et al., DNA repair (in press) Experiment Overall Design: There are six linker histone H1 variant in chicken. Linker histone was thought to be general gene supplesser. We established linker histone H1 variant mutant in chicken B-cell derived DT40 cell, and analyze total protein by 2D-PAGE to find up- or down- regulatd protein. In these mutant, there are some up regulated protein expression and down regulated protein expression (Takami et al., BBRC 268, 501-508 (2000), PubMedID 10679234). Experiment Overall Design: These 2D-PAGE experiment were limited at low density protein region, we use Affymetrix array to search the gene that were regulated specific linker histone H1 variant mutant. Experiment Overall Design: We assayed total gene expression profile in H1L and H1R deleted mutant cells. Experiment Overall Design: all mutant cells were cultured in normal culture condition in RPMI 1640 medium supplemented with 10 ÂµM 2-mercaptoethanol, 10% FCS (Biowest) and 1% chicken serum (Gibco) at 39.5ËC. Total RNA were isolated from exponently growing DT40 cells.

Gene expression in Histone H1 null mutant cells

Project description:In chicken DT40 cells, there are six linker histone H1 variants and 12 of coding genes. We have previously reported of 11 out of 12 H1 knock out DT40 cells (Takami et al., Genes to Cell 1997 [PMID:9491804]) but complete H1 null DT40 cells could not established, so far. We identified one of the H1 variant, H1R was involved in genomic instabilities (Hashimoto et al., DNA repair (2007) [17613284]), so we re-introduced floxed H1R-eGFP and mer-cre-mer into 11 out of 12 H1 knock out DT40 cells. Then we targeted last enedogenous H1, we successfully established conditional H1 KO cells (K11). Next we treated with tamoxifen to loop out floxed H1R-eGFP, and cloning H1 completely null cells (K11-5, and K11-7). We analysis those gene expression pattern in wild-type, K11, and K11-5 cells (Hashimoto et al., NAR (2010), PMID:20156997) Keywords: gene expression array-based, count

We analysis those gene expression pattern in wild-type, K11, and K11-5 cells Experiment Overall Design: Apoptosis is induced in H1 null cells, so we inhibit apoptosis with pan-caspase inhibitor, Z-VAD-FMK and extract RNAs.

Identification of chicken Interferon Stimulated Genes (ISGs) using Affymetrix GeneChip Chicken Genome Arrays

Project description:Recombinant chicken IFN1 was prepared as previously reported (Laidlaw et al, 2013) and was added in chicken embryo fibroblasts to a final concentration of 1000 U/ml. Confluent cells were treated with chicken IFNa or mock treated and incubated for six hours before harvesting. The experiment was repeated in triplicate with three different batches of CEFs.
