Capture-C in D. melanogaster carrying second (CyO) and third (TM3) balancer chromosomes
Ontology highlight
ABSTRACT: We used a Drosophila melanogaster line (a "double balancer") carrying balancer chromosomes for both the second (CyO) and third (TM3) chromosomes, and crossed it to an isogenic wild-type "virginizer" line. Trans-heterozygous adults from the F1 generation were further crossed to the wild-type parental line to obtain the pool of N1 embryos. Allele-specific chromosome conformation capture (Capture-C) was used to measure changes in chromatin organization on both chromosomes.

Trans-heterozygous adults from the F1 generation were further crossed to the wild-type parental line to obtain the pool of N1 embryos. Allele-specific chromosome conformation capture (Hi-C) was used to measure changes in chromatin organization on both chromosomes.
Project description:Hi-C was performed on 2 biological replicates of wild-type Drosophila embryos at 2-4 hrs after egg-laying. Each library was first checked on MiSeq and then deeply sequenced on HiSeq 2000 (4 lanes for each biological replicate)
Project description:Hi-C was performed on wild-type Drosophila melanogaster embryos at 6-8 hrs and 16-18 hrs after egg-laying, on 2 biological replicates per time point. Each library was first checked on MiSeq and then deeply sequenced on HiSeq 2000 (4 lanes for each biological replicate). This study completes the E-MTAB-12070 Hi-C dataset on 2-4 hrs wild-type Drosophila melanogaster embryos. Both studies use the same experimental procedures (protocols, sequencer model and run parameters)
Project description:Capture-C was performed on sonicated and amplified 3C libraries generated from nuclei isolated from 2-3h whole embryo samples or Mef2-/Elav-sorted nuclei from 6-8h and 10-12h embryo samples. Capture-C was performed on wildtype embryos. Capture-C was performed using two different Capture probe pools, one for TSS and one for CRM. TSS and CRM were hand curated for tissue- and stage-specific activity.
Project description:Capture-C was performed on sonicated and amplified 3C libraries generated from nuclei isolated from fixed 3-18h Drosophila whole embryo samples. Capture-C was performed on wildtype and embryos with deletions or insertions at loop anchors/genes at the respective loci (scyl-chrb or tsh-tio). Capture-C was performed using two different Capture probe pools, one indicated as left (scyl, tsh, salm) and one as right (chrb, tio, salr).
Project description:Chromosome conformation capture (4C-Seq) in Drosophila Twist-H2B embryos (carrying nuclear tag specifically in the mesoderm) during embryogenesis was performed, anchoring on 107 different viewpoints. Two timepoints (3-4hrs and 6-8hrs after egg laying) and two tissue context (whole embryo and mesoderm) were assayed. Two independent collections were performed at each timepoint.
Project description:DNase-seq over 3 matching developmental time points in Drosophila melanogaster and Drosophila virilis embryos was performed. The aim is to assess conservation of hypersensitive regions between two distantly related species. Samples were sequenced using Illumina HiSeq.
Project description:DNase-seq over 2 matching developmental time points in Drosophila melanogaster and Drosophila virilis embryos was performed. The aim is to assess conservation of hypersensitive regions between two distantly related species. Samples were sequenced using Illumina NextSeq. This Study is an extension to the previously published Study E-MTAB-3797.
Project description:This study contains a series of ChIP-seq experiments performed on nuclear material similar to what was used in Tissue- and Stage-specific Capture-C for selected TSS and CRM (BioStudies/ArrayExpress collection E-MTAB-9310). ChIP-seq with chromatin isolated from nuclei isolated from 2-3h whole embryos samples or Mef2-/Elav-sorted nuclei from 6-8h and 10-12h embryo samples was performed using anti-H3K27ac (Anti-Histone H3 (acetyl K27) antibody, Abcam #ab4729, purified polyclonal), anti-CTCF (rabbit anti Drosophila CTCF antibody, Reinkawitz lab, purified polyclonal), anti-Beaf (mouse anti Drosophila BEAF antibody, DSHB #1553420, monoclonal) and anti-Su(Hw) (goat anti Drosophila Su(Hw) antibody, Geyer lab, purified polyclonal) antibodies.

Allele-specific RNA-seq was used to measure changes in gene expression from both chromosomes.
