Sample GSM5884749 Query DataSets for GSM5884749
Status Public on Apr 26, 2022
Title amanitinPROseq_NT_Rep2
Sample type SRA
 
Source name HEK293T
Organism Homo sapiens
Characteristics cell line: HEK293T
genotype: WT
spike-in organism: Drosophila melanogaster
protocol/antibody: PRO-Seq, Mahat et al Nat Protoc, 11:1455-76; doi: 10.1038/nprot.2016.086
sequenced molecule: nascent RNA
Growth protocol Cells were cultured in 1X DMEM (Nacalai tesque) supplemented with 10% fetal bovine serum and 1X penicillin/streptomycin (Nacalai tesque) in a CO2 incubator (5% CO2) at 37°C.
Extracted molecule total RNA
Extraction protocol For PRO-seq, 25 million wild type or mutant HEK293T cells were mixed with 2.5 million Drosophila S2 cells (10:1 ratio), permeabilized, and incubated with biotin-labeled NTPs. Biotinylated RNA was hydrolyzed with NaOH, and biotin containing RNA fragments were enriched by affinity purification using streptavidin-coated magnetic beads. A 3′ sequencing adaptor was ligated to the biotinylated RNA, the 5′ cap was removed, 5′ OH was generated by base hydrolysis and converted to 5′ phosphate by treatment with T4 polynucleotide kinase, a 5′ sequencing adaptor was ligated to RNA. RNA was purified to enrich for biotinylated fragments with adaptor at both ends and reverse transcribed. Detailed methods are in PRO-Seq, Mahat et al Nat Protoc, 11:1455-76; doi: 10.1038/nprot.2016.086.Detailed methods are in PRO-Seq, Mahat et al Nat Protoc, 11:1455-76; doi: 10.1038/nprot.2016.086.
Ribo-depleted RNA-seq libraries were prepared using the TruSeq Stranded Total RNA Library Prep Gold (Illumina) following manufacturer's instructions. Libraries were checked for quality and quantity using Bioanalyzer. Equimolar concentrations of libraries were pooled, requantified and sequenced as 100 bp paired-end reads on the Illumina HiSeq 3000 instrument. Libraries for ChIP-seq and antibody-based in situ biotinylation-seq were prepared using TruSeq ChIP Library Prep Kit (Illumina) and IDT for illumina-TruSeq RNA UD Index (Illumina). Library purification and size selection were performed using Agencourt AMPure XP system. Libraries were checked for quality and quantity using Bioanalyzer. Equimolar concentrations of libraries were pooled, and sequenced as paired-end reads on the Illumina Novaseq 6000 platform (ChIP-seq) or Hiseq 2500 platform (antibody-based in situ biotinylation-seq). PRO-seq libraries were generated essentially as described in Mahat et al., 2016 (Nat Protoc, 11:1455-76; doi: 10.1038/nprot.2016.086). Primers RPI1, RPI2, RPI3 and RPI4 were used to barcode cDNAs from 293T-WT_Rep1 (Wild type, replicate 1), 293T-WT_Rep2 (Wild type, replicate 2), 293T-EAF1mut_Rep1 (Mutant EAF1, replicate 1), and 293T-EAF1mut_Rep2 (Mutant EAF1, replicate 2), respectively. PRO-seq libralies were pooled and sequenced as paired-end reads on the Illumina Novaseq 6000 platform. 4C-seq libraries werec generated essentially as described in Krijger et al., 2020 (Methods, 170: 17-32; doi: 10.1016/j.ymeth.2019.07.014). 4C-seq libralies were pooled and sequenced on Illumina Hiseq 2500 platform.
 
Library strategy OTHER
Library source transcriptomic
Library selection other
Instrument model Illumina NovaSeq 6000
 
Data processing Library strategy: PRO-seq
Basecalling and bcl to fastq generation was done using bcl2fastq2 v2.18 from illumina.
PRO-seq read counts were normalized according to the genomic coverage of mapped Drosophila reads using bedtools (version 2.29.2) and samtools (version 1.7).For PRO-seq data analysis of α-amanitin-treated samples, the read counts were normalized according to million rRNA reads to evaluate effect of α-amanitin on Pol II-dependent PRO-seq signals. rRNA reads were defined as reads mapped to chrUn_GL000220v1: 105424 -118780 and counted using bedtools.
Genome_build: GRCH38 and Drosophila melanogaster genome build5.41 from NCBI
Supplementary_files_format_and_content: BigWig files include normalized count data obtained from methods shown above.
