C INPUT phenobarbital donor14 |
| Sample type |
SRA |
| |
|
| Source name |
whole liver extract
|
| Organism |
Mus musculus |
| Characteristics |
age: 29-32 days
chip antibody: INPUT
treament: phenobarbital
tissue: liver
animal id: 14
experiment id: C
strain: B6C3F1/Crl (C57BL/6 male x C3H/He female)
|
| Treatment protocol |
Phenobarbital (Sigma 04710, 0.05% (w/v) in drinking water) was administered to one group through ad libitum access to drinking water for 28 days
|
| Growth protocol |
29–32 days old male B6C3F1/Crl (C57BL/6 ♂ x C3H/He ♀) mice were obtained from Charles River Laboratories (Germany). Animals were allowed to acclimatise for 5 days prior to being randomly divided into two treatment groups of five animals each. Phenobarbital (Sigma 04710, 0.05% (w/v) in drinking water) was administered to one group through ad libitum access to drinking water for 28 days. Mice were checked daily for activity and behaviour and sacrificed on the last day of dosing (day 28)

| Data processing |
base calling with CASAVA 1.8 for single-end and GERALD v1.52.6.1 for paired-end
for the paired-end data, mapping of reads with bowtie 0.12.7: bowtie --solexa1.3-quals -v 3 --best --strata -S -m 100 -5 11 -3 3 -I 0 -X 400
for the single-end data mapping was done with bowtie 0.12.5: bowtie --solexa1.3-quals -n 3 -l 36 --best --chunkmbs 512 --strata -S -m 100 -5 3
alignments were post-processed with samtools to create sorted and indexed BAM files
redundant alignments were removed (same alignment with same mismatches and genomic mapping)
the target genome was binned into 500 base pairs bins and reads counted per bin
the log2 fold change of IP (per sample and histone mark) over the input (background) is calculated
regions are further summarized (e.g. promotors, gene body), see supplementary file histoneMarkREsults3.txt
Genome_build: mm9
Supplementary_files_format_and_content: bedgraph files of enrichment (log2 library size normlaized read counts of IP over background) in bins of 500 base pairs; tab delimited enrichment (normalized by library size) of histone marks in different gene regions
