Gene expression in Histone H1 null mutant cells

ABSTRACT: 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.

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.

Transcriptome-wide identification of RNA-binding protein and microRNA target sites by PAR-CLIP: miRNA inhibition data

Project description:To obtain evidence that Argonaute (AGO) crosslink-centered regions (CCRs) indeed contain functional miRNA-binding sites, we blocked 25 of the most abundant miRNAs in HEK 293 cells (Figure 5C of PMID 20371350) by transfection of a cocktail of 2'-O-methyl-modified antisense oligoribonucleotides and monitored the changes in mRNA stability by microarrays (Figure 7A of PMID 20371350). Consistent with previous studies of individual miRNAs (Grimson et al., 2007), the magnitude of the destabilization effects of transcripts containing at least one CCR depended on the length of the seed-complementary region and dropped from 9-mer to 8-mer to 7-mer to 6-mer matches (Figure 7B of PMID 20371350). We did not find evidence for significant destabilization of transcripts that only contained imperfectly paired seed regions.

P0-cre marked neural crest cells in murine embryo

Project description:To elucidate the molecular features of craniofacial versus trunk neural crest cells (NCCs), we utilized P0-Cre/Floxed-EGFP mice that specifically label NCCs (Yamauchi et al., 1999 (PMID 10419695)). Craniofacial and trunk regions were isolated from P0-Cre/Floxed-EGFP mouse embryos at embryonic day E12.5, and dissociated cells were analyzed by flow cytometory in regard to the intensity of EGFP.

Calcineurin-dependent transcriptome in ICN1 (activated NOTCH1)-induced T cell acute lymphoblastic leukemia (T-ALL)

Project description:Activated NOTCH1 induces T-ALL in mice when transduced in bone marrow (BM) cells. T-ALL cells activate the calcineurin/NFAT pathway in vivo (Medyouf H. et al. Nat Med 2007 [PMID 17515895]). Through appropriate crosses, mouse ICN1-induced T-ALL were generated that include a ROSCreERT2 transgene and 2 copies of a CnB1 floxed alleles. Cohorts of secondary recipient mice were injected with these T-ALL cells, and when becoming leukemic, divided into 2 subgroups. Group 1 was treated with Tamoxifen (TAM), resulting in CnB1 gene deletion and inactivation of calcineurin. Group 2 was treated with carrier solvent (corn OIL), thus maintaining CnB1 and calcineurin activity. RNAs were extracted from flow cytometry-sorted leukemic cells. Details in Gachet S. et al. Leukemia 2013 (PMID 23689515).

Differential gene expression of meiotic drive system of Aedes aegypti

Project description:We conducted a whole transcriptome analysis of testes from a meiotic drive-carrying strain (T37) in comparison with a drive-sensitive strain (RED) using microarrays based on the complete annotated Ae. aegypti gene set. The T37 strain, which carries a strong meiotic drive gene (Mori et al., 2004 (PMID 15605641)), was established from mosquitoes collected in Trinidad. The RED strain is highly sensitive to the meiotic drive gene (Hickey and Craig, 1966 (PMID ); Mori et al., 2004 (PMID 15605641)).
