|
| Source name |
E14 mES cell line
|
| Organism |
Mus musculus |
| Characteristics |
cell line: E14 mES cell line
tag integration: osTIR1 was integrated into the genome using CRISPR-directed homologous recombination
treatment: Cells were left undisturbed on 10 cm plates for 48 hours prior to treatment. Cells were treated with 0.1% ethanol mixed into medium for the indicated time (hours). Cells were incubated at 37 degrees Celsius with 5% CO2 for the duration of treatment.
|
| Treatment protocol |
After 48 hours of undisturbed growth on 10 cm plates, medium was aspirated and cells were washed with DPBS. DPBS was aspirated and fresh medium was added containing 500 nM 3-Indoleacetic acid (3-IAA) or an equivalent volume of 100% ethanol. Plates were then left at 37 degrees Celsius with 5% CO2 for the indicated time before extraction.
|
| Growth protocol |
Murine embryonic stem cells were grown under feeder-free conditions in DMEM, supplemented with 10% Fetal Bovine Serum, 2 mM-Glutamine, 1X non-essential amino acids, 0.129mM 2-mercaptoethanol, 1000U/mL Leukemia Inhibitory Factor (LIF), 3 µM CHIR99021 GSK inhibitor (p212121), and 1 µM PD0325091 MEK inhibitor (p212121). Cells were passaged every 48 hours using trypsin (Gibco) and split at a ratio of ~1:8 with fresh medium. Routine anti-mycoplasma cleaning was conducted (LookOut DNA Erase spray, Sigma) and cell lines were screened by PCR to confirm no mycoplasma presence.

genomic DNA |
| Extraction protocol |
Cells were trypsinized, quenched, pelleted, washed with cold PBS, and resuspended in hypotonic buffer. Nuclei were pelleted and lysed cell debris (supernatant) removed. Nuclei were flash-frozen until time of use.

Nuclei were pelleted and lysed cell debris (supernatant) removed. Nuclei were flash-frozen until time of use. Nuclei were transposed for 30 minutes at 37C with 100 rpm shaking and Tn5 transposome (Diagenode). Libraries were amplified for 10 cycles of high-fidelity PCR

| Description |
Transposed for 30 minutes at 37C with 100 rpm shaking and Tn5 transposome (Diagenode). Libraries were amplified for 10 cycles of high-fidelity PCR
|
| Data processing |
Reads were trimmed to 25 bp and barcode adapter sequences removed using trim_galore
Reads mapped to mm10 genome using bowtie2, allowing for 1 mismatch
Duplicates were removed using Picard
Reads were filtered for quality using SAMtools (MAPQ ≥ 10)
Reads were size-selected into nucleosome-free (1-100 bp) size class
Reads were processed in deepTools by using the bamCoverage command to generate bigwig files detailing coverage genome-wide in 1 bp bins with RPGC normalization, using an effectiveGenomeSize of 2308125349
Assembly: mm10
Supplementary files format and content: bigwig
