Sample GSM1298382 Query DataSets for GSM1298382
Status Public on Jun 01, 2014
Title HS_2 (HE009)
Sample type SRA
 
Source name neuronal aggregates (day 50) derived from induced pluripotent stem cells
Organism Homo sapiens
Characteristics tissue: 3-dimensional neuronal aggregates that resemble a first trimester telencephalon
sample group: 39C for 24 hrs
Treatment protocol For the HS experiment, a group of 49 day old aggregates was placed in an incubator set at 39 degrees C for 24 hours, while control sets of aggregates were maintained at 37 degrees C. The incubator conditions were otherwise unchanged (ambient O2, 5% CO2, 85% humidity).
Extracted molecule total RNA
Extraction protocol total cellular RNA was isolated using the miRNeasy Kit (Qiagen) according to the manufacturer’s protocol
RNA libraries were prepared for sequencing using standard Illumina protocols. Briefly, total RNA were extracted to produce cDNA using DT-T7 primers. The blunt, phosphorylated ends were treated with Klenow fragment (32 to 52 exo minus) and dATP to yield a protruding 3- 'A' base for ligation of Illumina's adapters which have a single 'T' base overhang at the 3’ end. After adapter ligation DNA was PCR amplified with Illumina primers for 15 cycles and library fragments of ~250 bp (insert plus adaptor and PCR primer sequences) were band isolated from an agarose gel. The purified cDNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer following the manufacturer's protocols.

Data processing We obtained 101-bp mate-paired reads from DNA fragments of with an average size of 250-bp (standard deviation for the distribution of inner distances between mate pairs is approximately 100 bp). RNA-Seq reads were aligned to the human genome (GRCh37/hg19) using the software TopHat (version 2.0.8). We counted the number of fragments mapped to each gene annotated in the GENCODE database (version 18). The category of transcripts is described at http://vega.sanger.ac.uk/info/about/gene_and_transcript_types.html. Transcript abundances were measured in Transcripts Per Million (TPM), which is calculated by multiplying the estimated fraction of transcripts made up by a given gene by 106.
