Project description:Determination of the genome-wide distribution of the Mcm2-7 helicase by chromatin immunoprecipitation in the Drosophila Kc167 cell line at the beginning of S phase. Kc167 cells were arrested at the G1/S transition with hydroxyurea (HU). Goal was to evaluate changes in the genome-wide Mcm2-7 distribution throughout the cell cycle, and how this relates to the excess Mcm2-7 loaded onto chromatin in G1. ChIP-Chip of Mcm2-7 in HU compared to input genomic DNA. Biological Replicates: 2

Project description:Determination of the genome-wide distribution of the Mcm2-7 helicase by chromatin immunoprecipitation in the Drosophila Kc167 cell line at the end of S phase. Kc167 cells were synchronized by first arresting at the G1/S transition with hydroxyurea (HU), and then releasing from the HU arrest point for 6 hours. Goal was to evaluate changes in the genome-wide Mcm2-7 distribution throughout the cell cycle, and how this relates to the excess Mcm2-7 loaded onto chromatin in G1.

Project description:Determination of the genome-wide distribution of ORC by chromatin immunoprecipitation in the Drosophila Kc167 cell line at the beginning of S phase. Kc167 cells were arrested at the G1/S transition with hydroxyurea (HU). Goal was to test whether the ORC binding distribution remained the same between G1 and S.

Project description:Mcm2-7 ChIP in pre-meiotic and pre-mitotic cells, axis factor ChIP in wild-type and replication compromised strains in meiosis Multiple studies of meiotic chromosomes were undertaken. To study DNA replication, the locations of replicative helicase (Mcm2-7) were mapped in pre-meiotic and pre-mitotic cells, and DNA replication profiles were created for pre-meiotic S (meiS) and pre-mitotic S (mitS) phases. Early origins were mapped in hydroxyurea for wild-type cells in mitS + 200mM HU, and meiS +20mM HU for wild-type, sml1, rec8 and spo11 deletion cells. Rec8, Hop1 and Red1 binding to meiotic chromosomes was evaluated using ChIP-chip in wild-type cells with and without 20 mM HU, and in cdc6-mn and clb5 clb6 delete cells. Finally, meiotic DNA double-strand breaks (DSBs) were mapped in cdc6-mn dmc1 delete cells by measuring the ssDNA that accumulates at DSB hotspots.

Project description:modENCODE_submission_709 This submission comes from a modENCODE project of David MacAlpine. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: Early origins of replication were identified by treating cells with hydroxyurea (HU), a potent inhibitor of nucleotide synthesis, in the presence of the nucleotide analogue BrdU. Treatment of synchronized Kc167 cells with HU stalls replication forks and activates the intra S-phase checkpoint, thereby limiting BrdU incorporation to those sequences immediately adjacent to early activating replication origins. BrdU enriched sequences surrounding early origins of replication are then enriched by immunoprecipitation with an anti-BrdU antibody. Early origins are then detected by hybridization to Agilent genomic tiling arrays. Peaks are called using MA2C (http://liulab.dfci.harvard.edu/MA2C/MA2C.htm) Keywords: CHIP-chip For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CHIP-chip.

Project description:Analysis of the response to hydroxyurea in a yeast aft1 mutant strain compared to wild-type strain (BY4741 or BY4742 backgrounds). Cells were grown in YPD rich medium containong 200 mM hydroxyurea (HU) for 2 hours. Analysis of the response to hydroxyurea in a yeast aft1aft2 mutant strain (Y18aft2d) compared to wild-type strain (CM3260). Cells were grown in YPD rich medium containing 200 mM hydroxyurea (HU) for 2 hours. Gene expression changes due to the aft1 mutation were also analysed in absence of HU (BY4741 background). Analysis of mid-term response to hydroxyurea in a yeast wild-type strain (W303a). Cells were grown in YPD rich medium containing 200 mM hydroxyurea (HU) for 2 hours. Gene expression changes were analysed compared to the same strain grown in the same medium without HU. Keywords: repeat sample

Project description:Hydroxyurea (HU) is toxic to Sulfolobus cells. To address the basis of the HU toxicity, we performed transcriptome analyses on untreated cells and cells following exposure to 5 mM HU for 4 hours.
