Sample GSM1101725 Query DataSets for GSM1101725
Status Public on May 13, 2013
Title ChIP_H3K4me1_C2C12_6hDAPT_repl1
Sample type SRA
 
Source name C2C12_ChIP_H3K4me1_6hDAPT
Organism Mus musculus
Characteristics cell line: C2C12
cell type: Mouse myoblast cell line (established from thigh muscle from an adult C3H strain female)
technique: ChIP-sequencing
chip antibody: anti-H3K4me1
chip antibody vendor: Diagenode
Treatment protocol DAPT treatments: DAPT dissolved in DMSO (Calbiochem) was added to Fc only dishes at a final concentration of 20µM for 6h or 24h.
Delta treatments: For ligand-dependant activation of Notch signaling, cells were grown in the presence of the extracellular domain of Delta-like 1 fused to the Fc fragment of human IgG (Hicks et al., 2002) (kindly provided by N.Gupta upon permission from G.Weinmaster). Culture dishes were first coated with 10 µg/ml anti-Fc antibody for 1h at RT. Dishes were then incubated with conditioned medium from transfected 293T cells expressing the fusion proteins, for 1h at RT. C2C12 cells were plated in fresh medium and grown for 6h or 24h on the immobilized-ligand containing dishes.
GFP or NICDGFP protein induction: the cells were induced for 8h with 2ug/ml Doxycyclin.
Growth protocol C2C12 cells were cultured in DMEM medium supplemented with 20% fetal bovine serum and 1% penicillin/streptomycin (Invitrogen) at 37 °C in 5% CO2 atmosphere
Extracted molecule genomic DNA
Extraction protocol Cells were trypsinized according to standard procedures. A cell suspension with cell density of 5 million/ml was made in cell medium. Cells were subsequently cross-linked for 30 min at RT in medium plus 1% formaldehyde and 1/14 volume of buffer A (0.1M NaCl, 1mM EDTA pH8, 0.5mM EGTA pH8, 50mM HEPES pH7.6), quenched with 0.125 M glycine and washed at 4°C with the following buffers: (i) PBS, (ii) buffer B: 0.25% Triton-X-100, 10mM EDTA pH8, 0.5mM EGTA pH8, 20mM HEPES pH7.6, (iii) buffer C: 0.15M NaCl, 1mM EDTA pH8, 0.5mM EGTA pH8, 50 mM HEPES pH7.6. During each washing step cells were rotated for 10 min at 4°C and subsequently centrifuged for 7 min at 500g 4°C. Cells were then suspended in ChIP incubation buffer (0.15% SDS, 1% Triton-X-100, 0.15M NaCl, 1mM EDTA pH8, 0.5mM EGTA pH8, 20mM HEPES pH7.6, 1x protease inhibitor cocktail complete (Roche)) at 20 million/ml and sheared using a Bioruptor (Diagenode) with the following settings: high power, 30s on/off, 18 cycles. Sonicated chromatin was centrifuged for 5 min at 13000 rpm in eppendorf tubes, supernatant was snap-freezed in liquid nitrogen and stored at -80 °C or directly used in ChIPs. For one ChIP, 100 µl chromatin was incubated with 2 µg antibody, 20 µl 50% protein A/G bead (Santa Cruz), in 1x ChIP incubation buffer with 0.1% BSA in a total volume of 300 µl o/n at 4°C. Beads were then washed with the following buffers: twice with buffer1: 0.1% SDS, 0.1% NaDOC, 1% Triton-X-100, 0.15M NaCl, 1mM EDTA pH8, 0.5mM EGTA pH8, 20mM HEPES pH7.6, once with buffer2: 0.1% SDS, 0.1% NaDOC, 1% Triton-X-100, 0.5M NaCl, 1mM EDTA pH8, 0.5mM EGTA pH8, 20mM HEPES pH7.6, once with buffer3: 0.25M LiCl, 0.5% NaDOC, 0.5% NP-40, 1mM EDTA pH8, 0.5mM EGTA pH8, 20mM HEPES pH7.6, and twice with buffer4: 1mM EDTA pH8, 0.5mM EGTA pH8, 20mM HEPES pH7.6. During each washing step beads were rotated for 5 min at 4°C and subsequently centrifuged for 2 min at 4000 rpm 4°C. Precipitated chromatin was then eluted from beads in 200 µl elution buffer (1% SDS, 0.1M NaHCO3) for 40 min at RT. Materials (precipitated chromatin or input chromatin in elution buffer) were decross-linked for 5h at 65 °C with addition of 200 mM NaCl. DNA was purified on QIAquick spin columns according to QIAGEN protocols. For sequencing, 6-8 ChIPs were pooled.
Strand-specific RNA-seq using RiboZero. Total RNA was extracted using RNeasy Mini and Micro kit (Qiagen) following the manufacturer instruction. Ribosomal RNA was removed from 200 ng total RNA using the Ribo-Zero rRNA Removal Kit Low Input for Human/Mouse/Rat (Epicentre Biotechnologies), according to the manufacturer’s protocol. RNA was subsequently fragmented in fragmentation buffer (40 mM Tris-Ac pH8.2, 100 mM KAc, 30 mM MgAc) for 90 s at 95 ºC and purified by ethanol purification. cDNA was synthesized using random hexamers by Superscript III Reverse Transcriptase (Invitrogen), in presence of 6 ng/µl ActinomycinD. cDNA was purified (MinElute Reaction Cleanup Kit, QIAGEN) and subjected to second strand synthesis by E.Coli DNA Polymerase I (Invitrogen) and E.Coli DNA Ligase (New England Biolabs) in the presence of RNaseH (Ambion). For second strand synthesis dUNTPs were used, containing dUTP instead of dTTP. After second strand synthesis, ds-cDNA was purified (MinElute Reaction Cleanup Kit, QIAGEN) and prepared for Illumina sequencing according to standard procedures using the DNA sample Prep Kit (Illumina, cat# IP-102–1001) and starting from the A-tailing step. After ligation of adapters, a 200 bp band is excised using the E-Gel system (Invitrogen). Before final PCR amplification uracil containing second strand DNA was removed by USER enzyme (New England Biolabs) for 15 min at 37 ºC followed by 10 min at 95 ºC in 1x Phusion Buffer (Finnzymes).
1 to 20 ng was used for library preparation using the ChIP-seq DNA sample Prep Kit (Illumina, cat# IP-102–1001) using the recommended protocol. After ligation of adapters, a 300 bp band is excised using the E-Gel system (Invitrogen), which correspond to a 234 bp fragment of genomic DNA. PCR enrichment of adapter-ligated DNA was done using 14 cycles of PCR.

Description Sample 31
Data processing ChIP-seq. Cluster generation and sequencing-by-synthesis (36 bp) was performed using the Illumina Genome Analyzer IIx (GAIIx) platform according to standard protocols of the manufacturer (Illumina). The image files generated by the Genome Analyzer were processed to extract DNA sequence data. Sequences were aligned to the mouse (mm9) reference genome using the Illumina Analysis Pipeline allowing, one mismatch. Only the tags uniquely aligning to the genome were considered for further analysis. Duplicated reads were discarded to obtain a non-redundant set. Further analysis was performed using the 36 bp sequence reads. The output data were converted to Browser Extensible Data (BED) files for downstream analysis and Wiggle (WIG) files for viewing the data in the UCSC Genome Browser. All sequence analyses were conducted based on the Mus Musculus mm9 genome assembly.
