Transcriptome


Description

This track represents the RNA signal based on stranded-specific RNA-seq and smallRNA-seq datasets. The data were generated by the EMC Group at McGill based on a uniform processing pipeline. These datasets were used in all downstream analysis pipelines by members of the EMC Group at McGill.

Methods

Samples Preparation

Tissues samples in TRIzol (Invitrogen) were disrupted using a POLYTRON machine. Total RNA from cells and tissues were extracted using miRNeasy kit (including a DNaseI treatment step) and quality assessed by Agilent 2100 BioAnalyzer (Agilent Technologies).

Library Preparation

Libraries for RNA-seq and smallRNA-seq were prepared according to the Illumina TruSeq protocols (with the Gold option for RNA-seq samples). Size selection (130bp-170bp) of smallRNA-seq libraries was performed using 3% gel cassettes (Sage Science). Libraries qualities were assessed by Agilent 2100 BioAnalyzer (Agilent Technologies).

Sequencing and Mapping

Samples were indexed and sequenced in an Illumina HiSeq 2000 (100 bp paired-end and 50 bp single-end reads for RNA-seq and smallRNA-seq respectively).

Credits

Data were generated and processed in the Epigenomic Mapping Centre (EMC) and Epigenomic Data Coordination Centre (EDCC) of McGill University and the Genome Quebec Innovation Centre (Montreal,QC, Canada). Both EMC and EDCC belong to the Canadian Epigenetics, Environment and Health Research Consortium (CEEHRC) associated with IHEC. Funding was obtained from the Canadian Institutes of Health Research (CIHR) in partnership with Genome British Columbia and Genome Quebec.
