Sample GSM3790265 Query DataSets for GSM3790265
Status Public on Nov 22, 2019
Title Fetal_HeliosKO_IL2iTreg_3
Sample type SRA
Source name Fetal spleenocytes
Organism Homo sapiens
Characteristics donorid: F83
genotype: Helios Knockout
age: 22.2 weeks
Sex: Male
Treatment protocol For fetal iTreg cells,CRISPR-Cas9 editing via nucleofection of Cas9 complex with the Helios gRNA1 (HeliosKO) or non-targeting guide (HeliosWT) was carried out prior to Treg differentiation
Growth protocol Treg differentiation - Cells were stimulated with anti-CD3/CD28/CD2 tetratmers (Stemcell) in culture media supplemented with with 10ng/mL IL-2 (Peprotech) in the presence of absence of 50ng/mL TGFb (Peprotech)
Extracted molecule total RNA
Extraction protocol Cells were harvested on Day 6 of culture, and total RNA was extracted from 25,000 cells using the Nucleospin XS RNA kit (Machery Nagel)
Libraries were constructed using a standard Illumina protocol following manufactorer instructions using the NEBNext® Ultra™ II Directional RNA Library Prep Kit
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 4000
Description Sequencing batch 1
Data processing Fastq files were mapped to hg19 with Bowtie 2
Read counts per gene was obtained using RSEM
TMM normalization and differential expression analysis performed using EdgeR package for Bioconductor
Separate comparisons were performed for adult and fetal iTreg cells, and fetal HeliosKO and HeliosWT iTreg cells using generalized linear models
TMM read counts for HeliosKO versus HeliosWT comparisons are normalized for paired samples and batch effects due to two sequencing runs carried out, and are supplied as log2 read counts.
Genome_build: hg19
Supplementary_files_format_and_content: Generalized linear model output with fold change and FDR in text files for both comparisons. TMM normalized read counts for both comparisons in txt files.
