Sample GSM4954718 Query DataSets for GSM4954718
Status Public on Jan 28, 2021
Title hESC ZNF91 wt5 RNA seq rep 1
Sample type SRA
 
Source name hESCs
Organism Homo sapiens
Characteristics cell type: H9 Human embryonic stem cells
genotype: ZNF91 wt
crispr clone: wt5
Treatment protocol H9 hESCs were transfected with two gRNAs targeting ZNF91 cloned into pX330-SpCas9-HF1 and clonally expanded
Growth protocol H9 human embryonic stem cells were grown on matrigel (Corning) coated dishes. They were cultured in hESC medium that was incubated with mouse embryonic fibroblasts (MEFs) for 24 hours. HESC medium consisted of: DMEM/F12 supplemented with 2mM L-glutamine (Invitrogen), 20% knockout serum replacement (Gibco), penicillin/streptomycin (Invitrogen), non-essential amino acids (Invitrogen), 0.1mM β-mercaptoethanol (Invitrogen). Medium was supplemented with basic fibroblast growth factor (sigma, 8ng/μl) and changed daily to secure pluripotency of hESCs. For maintenance of the culture, cells were grown in colonies and passaged manually by cutting the colonies with a needle
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using Trizol according to the manufacturer's protocol, followed by a DNAse treatment and RNA purification using the RNA clean and concentrator kit (Zymo research). Ribosomal RNA was depleted from total RNA with the rRNA depletion kit (NEB# E6310)
NEB Next Ultra Directional RNA Library Prep Kit (NEB #E7420) was used to prepare Samples for sequencing at an illumina Hiseq 4000 device.

Data processing Read quality assessment using FASTQC
Trimmomatic (Bolger et al. 2014)⁠ was used to clip adapter sequences and trim low quality reads.
Reads were aligned to the human genome (Hg19 version) using STAR (Dobin et al. 2013)⁠ with default settings except: outFilterMismatchNmax=2 and outFilterMultimapNmax=10, outWigType=bedGraph, outSAMtype=BAM SortedByCoordinate
Raw read counts of genes were determined with FeatureCounts (Liao et al. 2014)⁠ using Hg19 KnownGenes.GTF from UCSC for annotation (downloaded 12th September 2016). Only properly paired reads were counted (-B) and the library was reversely stranded (-s 2). Genes were summarized at metalevel (default), whereas TEs were summarized at the feature level (-f)
DEseq2 (Love et al. 2014)⁠ was used to normalize raw counts, perform principal component analysis and differential expression analysis of genes and repeats. For differential expression analysis of SVA elements Log2FC >3 was considered differentially expressed, because SVA expression levels were too low to determine adjusted p values adequately
