Study: Atlas of RNA sequencing profiles of normal human tissues
show Abstracthide Abstract
Comprehensive analysis of molecular pathology requires a collection of reference samples representing normal tissues from healthy donors. There is a shortage now of the gene expression data for human healthy tissues. The available data can either lack biological replicates or represent tissues adjacent to tumors removed during surgery that have signs of pathology and inflammation. For the available limited collections of normal tissues from post mortal donors, there is a problem of data incompatibility, as different datasets were generated using different experimental platforms and cannot be merged in a single panel. Here, for the first time, we construct and deposited a gene expression database of normal human tissues based on uniformly screened original sequencing (Illumina HiSeq 3000) data. A total of 148 solid tissue samples representing 20 organs were taken from post-mortal human healthy donors killed in road accidents no later than 36 hours after death. Blood and bone marrow samples were taken from 6 and 11 healthy volunteers respectively. The materials were collected since 2012 and stored until gene expression profiles were obtained by using the same reagents and protocols. Data consistency was confirmed by hierarchical clustering and principal component analysis (PCA). Our data can be useful to all those working with the analysis of human gene expression. Overall design: A total of 148 solid tissue samples representing 20 organs were taken from post-mortal human healthy donors killed in road accidents no later than 36 hours after death. Prior to RNA extraction solid normal tissue samples were stored either in RNAlater or as Formalin-Fixed Paraffin-Embedded (FFPE) blocks. Blood and bone marrow samples were taken from 6 and 11 healthy volunteers respectively and subjected immediately to RNA extraction. Following ribosomal RNA depletion and RNA libraries construction transcription profiles of the samples were obtained using Illumina HiSeq 3000.

Construction protocol: For solid tissue biosamples, RNA extraction was performed immediately before preparation of sequencing libraries using QIAGEN RNeasy Kit (Qiagen) for tissues in RNAlater and using the RecoverAll™ Total Nucleic Acid Isolation Kit for FFPE (Invitrogen) following the manufacturer 's protocol. Then RNA Integrity Number (RIN) was measured using Agilent 2100 bio-Analyzer. Agilent RNA 6000 Nano or Qubit RNA Assay Kits were used to measure RNA concentration. The Kit for further depletion of ribosomal RNA was selected based on total amount of RNA in every sample: (i) when total amounts of RNA were less than 25 ng, Clontech Smarter stranded total RNA kit-pico (Mammalian only) was used; (ii) when total amount of RNA exceeded 25ng, KAPA RNA Hyper with RiboErase (KAPA Biosystem) kits were used. For library preparations, we used Ovation® Universal RNA-Seq System 1-96 and KAPA HyperPrep Kit according to the manufacturer's recommendations. Different adaptors were used for multiplexing samples in one sequencing run. Library concentrations and quality were measured using Qubit ds DNA HS Assay kit (Life Technologies) and Agilent Tapestation (Agilent). RNA sequencing was performed using Illumina HiSeq 3000 equipment for single-end sequencing, 50 bp read length, for approx. 30 million raw reads per each sample. Data quality check was done on Illumina SAV. De-multiplexing was performed with Illumina Bcl2fastq2 v 2.17 program.
