Sample GSM2335051 Query DataSets for GSM2335051
Status Public on Oct 22, 2019
Title Replicate1,chrRNA-seq WildType
Sample type SRA
 
Source name HeLa cells
Organism Homo sapiens
Characteristics cell type: cervical cancer cells
genotype/variation: wild type
Treatment protocol Lipofectamine 2000 was used to deliver RNAseH1 over-expressing plasmid (pRNH1-GFP), RNaseH1 catalytically dead mutant (pRNH1-D210N-GFP) Rnase H1 non binding ctalytically dead mutant (pRNH1-WKKD-GFP) and pGFP. For RDIP-seq experiments recombinant RNase H was added the sonicated HeLa cells before S9.6 immunoprecipitation. All HeLa cells used in Chromatin associated RNA-seq and ChrCAP-seq were GFP FACs sorted. For ChrCAP-seq, chromatin RNA were treated with Terminator exonuclease followed by calf intestine phosphatase before CAP-CLIP (5' pyrophosphatase) treatment.
Growth protocol HeLa cells were maintained in DMEM supplemented with 10%FBS
Extracted molecule total RNA
Extraction protocol Lysates were clarified from sonicated nuclei and 1) RNA:DNA hybrids were isolated with S9.6 antibody for RDIP-seq 2) RNA:DNA hybrids were isolated with GFP antibody for RR-ChIP-seq
For the RDIP-seq and RR-ChIP-seq, the RNA component of the R-loop was used to prepare the library using NEBNext Ultra II Directional RNA Library Prep Kit for Illumina, (E7760S) according to manufacturer's guidelines. For the ChrRNA-seq and ChrCAP-seq, chromatin associated RNA was used for library prepration as for RDIP-seq.

Description chrRNA-seq
chromatin RNA
Data processing Library strategy: chrRNA-seq
For chrRNA-seq, adaptors were trimmed using Cutadapt. Paired-end reads for each sample were mapped to human genome reference assembly GRh37/hg19 (build 37.2, February 2009) with Tophat v. 2.0.13 with parameters -g 1 -r 3000 --no-coverage-search.
RR-ChIP-seq reads were demultiplexed and aligned to reference genome hg19/GRCh37 using Bowtie2 alignment software.Plus and minus strand were assigned to mapped reads using SAMtools. RR-ChIP-seq peaks were called using MACS2 algorithm with default options
Genome_build: hg19
Supplementary_files_format_and_content: BigWig file containing read densities from RNA-seq experiments.
