Sample GSM4224890 Query DataSets for GSM4224890
Status Public on Dec 18, 2019
Title HI_entrained_RNA-seq_CT8
Sample type SRA
Source name Primary human adult islets
Organism Homo sapiens
Characteristics tissue: Primary human adult islet
treatment: entrained to circadian metabolic rhythms
Growth protocol Undifferentiated stem cells were maintained as aggregates in supplemented mTeSR1 medium (StemCell Technologies) using spinner flasks (Corning) set at a 70rpm rotation rate in a 37ºC 5% CO2 incubator. Directed hPSC differentiation into islet cells was conducted as described in the methods of (Alvarez-Dominguez et al. 2019).
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using the miRNeasy kit (QIAGEN) according to the manufacturer’s instructions. Ribosomal RNA was depleted from total RNA using the Ribo-Zero Gold Kit (Epicentre, Madison, WI).
Directional cDNA libraries were prepared using a KAPA Biosystems Stranded RNA-seq Library Preparation kit, pooled, and sequenced on an Illumina HiSeq2000 platform across multiple lanes.
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
Data processing Sequencing reads were mapped to the human hg38 reference genome assembly using STAR (Dobin et al., 2013) with default parameters. Gene expression based on GENCODE annotations (Harrow et al., 2012) was determined using RSEM (Li and Dewey 2011). Genes with expected count values >=10 across all samples were retained, normalized by library scaling using DESeq2 (Love, et al. 2014), and used for downstream analyses.
