Sample GSM8248519

Query DataSets for GSM8248519

Status

Public on May 20, 2024

Title

CBMC_PGE2_2

Sample type

SRA

Source name

Cord Blood

Organism

Homo sapiens

Characteristics

tissue: Cord Blood
cell type: Mast cell
treatment: 1uM PGE2
time point: 72 hours

Treatment protocol

Murine BMMCs (50,000 cells/well) were stimulated with 10 ng/mL of IL-33 and/or 1 µM of PGE2 for 24 hours in biologic quadruplicate. CBMCs were rested at 50,000 cells/100 uL in media containing SCF (100 ng/mL) overnight prior to stimulation with 1 µM PGE2 for 72 hours in technical duplicate

Growth protocol

MCs were cultured in RPMI 1640 supplemented with 10% FBS, 1% pen-strep, and 55 micromolar of 2-mercaptoethanol with 50 ng/mL SCF and 30 ng/mL IL-3 (mouse) or 10 ng/mL IL-10, 50 ng/mL IL-6, and 100 ng/mL SCF (human).

Extracted molecule

total RNA

Extraction protocol

Cells were spun down and resuspended in TCL buffer (Qiagen) with 1% 2-mercaptoethanol. Lysate containing 1,000 cells was transferred into low-bind plates for sequencing through the Broad Institute Genomics Platform
SmartSeq2 libraries were prepared according to the SmartSeq2 protocol (Picelli et al, 2013, 2014) with some modifications (Trombetta et al, 2014). Briefly, total RNA was purified using RNA-SPRI beads. Poly(A)+ mRNA was converted to cDNA which was then amplified. cDNA was subject to transposon-based fragmentation that used dual-indexing to barcode each fragment of each converted transcript with a combination of barcodes specific to each sample. Barcoded cDNA fragments were then pooled prior to sequencing. Sequencing was carried out using an Illumina NextSeq500 as paired- end 2x25bp with an additional 8 cycles for each index.

Description

CBMC_PGE2_2

Data processing

Reads were pseudoaligned to the GrCH38 (human) or GRCm39 (mouse) assembly using Kallisto (Bray et al, 2016) with default settings.
Transcript-level (human) or gene-level (mouse) expression data was imported into R using TXImport (Soneson et al, 2015)
Assembly: GrCH38 (human) or GRCm39 (mouse)
Supplementary files format and content: TXImport file containing abundance, counts, and length
