Title |
MCIDAS_dnE2F4_9h_RNAseq_rep_3 |
Sample type |
SRA |
|
|
Source name |
animal cap (ectoderm)
|
Organism |
Xenopus laevis |
Characteristics |
tissue: animal cap (ectoderm) harvest time/stage: 9h @ 22 deg after mid-11 (st 18) injected mrna: MCIDAS-HGR+dnE2F4
|
Treatment protocol |
Animal caps containing inducible constructs (human glucocorticoid receptor fusion proteins) were induced with 20 micromolar dexamethasone at mid-stage 11.
|
Growth protocol |
Animal caps (ectoderm) dissected from embryos at stage 10 and cultured in 0.5x MMR. 20 animal caps per condition were used for RNAseq; ~300 animal caps were used per condition for ChIPseq.
|
Extracted molecule |
polyA RNA |
Extraction protocol |
mRNAs were obtained with proteinase K digestion, phenol chloroform extraction and precipitated with ethanol, treated with Dnase, extracted with phenol chloforom, and precipitated with ethanol. For ChIPseq embryos were first fixed in 1% formaldehyde for 30 minutes and lysed in RIPA buffer prior to sonication. See our manuscript (PMID: 24934224) for a more detailed protocol. RNAseq libraries were constructed with Illumina Truseq v2 non-stranded mRNA kits. Following IP, ChIPseq libraries were constructed with end repair mix (NEB), a-tailed (NEB), Truseq v2 adapters ligated (Illumina, NEB) and amplified with Phusion polymerase (NEB).

Data processing |
RNAseq reads aligned to transcriptome with RNA-STAR (PMID: 23104886) RNAseq aligned reads counted with eXpress (PMID: 23160280) RNAseq counts normalized and differential expression tested with DESeq (PMID: 23975260) ChiPseq reads aligned to genome with bowtie2, http://bowtie-bio.sourceforge.ne t/bowtie2/index.shtml, mapping quality scores > 20 retained ChiPseq aligned reads were pooled and peaks called with HOMER (PMID: 20513432) Genome_build: Genome: JGI X. laevis v7.1 Genome_build: Transcriptome: Mayball interim models, http://daudin.icmb.utexas.edu/ Supplementary_files_format_and_content: RNAseq files are output from eXpress, ChIPseq peaks are bed files
