Project description:modENCODE_submission_720 This submission comes from a modENCODE project of David MacAlpine. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: Most terminally differentiated Drosophila tissues are either polyploid or polytene. Unlike normal chromosomes, where the entire chromosome must be replicated exactly once, polytene chromosomes are often differentially replicated with many regions underreplicated and some overreplicated. We will characterize five different polytene tissues using comparative genomic hybridization (CGH) to identify differentially replicated regions of each chromosome. These studies will also identify tissue specific amplicons, where the replication mediated amplification of specific loci is essential for up-regulation of mRNA levels encoding proteins critical for development. The differential replication of polytene chromosomes in Drosophila will provide a unique opportunity to understand how developmental cues and chromosomal domains influence replication initiation.

Project description:modENCODE_submission_710 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 S2-DRSC 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.
