Sample GSM5945922 Query DataSets for GSM5945922
Status Public on Mar 27, 2023
Title st9_hdac1_we_amanitin_rep2
Sample type SRA
 
Source name whole embryos
Organism Xenopus tropicalis
Characteristics strain: wildtype
chip antibody: HDAC1 (Cell Signaling, 34589S)
treatment: a-Amanitin injected (6pg/embryo)
Treatment protocol For a-Amanitin injection, 1-cell staged embryos were injected at 6pg/embryo. For TSA treatment, 4-cell staged embryos were immersed in 100nM TSA in 1/9 MMR or equavalent volume of DMSO
Growth protocol Xenopus tropicalis embryos were obtained by in vitro fertilization according to Ogino et al. (2006) and staged according to Nieuwkoop and Faber (1994). All embryos were cultured in 1/9X Marc’s modified Ringers (MMR) at 25C.
Extracted molecule genomic DNA
Extraction protocol For embryo dissection, animal caps or vegetal mass explants were dissected from late blastula embryos in 1X MMR, TSA treatment to embryos were maintained during dissection
For ChIP-seq, NEBNext Ultra II DNA library prep (E7645S) protocol was followed. For RNA-seq, NEBNext Ultra II RNA library prep (E7770S) protocol was followed.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NovaSeq 6000
 
Data processing The multiplexed libraries were sequenced on the Novaseq 6000. The version of Novaseq control software was NVCS ver 1.7.0 with real time analysis software, RTA 3.4.4.
For ChIP-seq, reads were aligned to Xenopus tropicalis v10.0 genome (Xenbase) using Bowtie2 v2.4.4. For RNA-seq, reads were aligned to Xenopus tropicalis v10.0 genome (Xenbase) using STAR v2.7.3a
For ChIP-seq, PCR duplicates were removed from aligned bam files using Samtools v1.10. For RNA-seq, RSEM v1.3.3 was used to calculate raw counts and expression values in transcripts per million (TPM)
For non-histone ChIP-seq, peaks were called using Macs2 v2.7.1 followed by IDR analysis using idr v2.0.4.2 in anaconda v4.11.0. For histone ChIP-seq, peaks were called using Macs2 v2.7.1 followed by reproduciable peak analysis using overlap method in Bedtools v2.29.2. For RNA-seq, differential expression analysis was performed using edgeR v3.36.0 in R v4.1.2
For ChIP-seq, bigwig files were generated from PCR deduplicated bam using Deeptools v3.5.0
Assembly: Xenopus tropicalis v10.0 (Xenbase)
Supplementary files format and content: For ChIP-seq, IDR peak bed files were included. For RNA-seq, raw count files were included
