Atlas of RNA sequencing profiles of normal human tissues

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.

Impact of tissue source type on gene expression profiles of normal human kidney

Project description:Normal human tissue is critical as a reference control in biomedical research. Yet access to high quality human tissue can be challenging due to clinical, logistical and ethical issues. Possible human normal tissue source types include non-transplantable tissues from organ donors (OD), post-mortem cadaveric tissues (CAD), and surgical resections of normal adjacent tissues (NAT) in cancer patients. But few studies have comprehensively explored the impact of these source types on the biological profile of the tissue. We assembled a panel of human normal kidney tissue from 91 donors representing OD, CAD, and NAT, as well as the matching kidney tumor. Histopathologic and molecular profiles by RNASeq analysis revealed clear differences between tumor and normal samples, regardless of the source type. Among the normal samples, there was a general similarity between source types, with little evidence of a field cancerization effect in the NAT. Differential gene expression and enrichment analyses indicated differences among source types in immune system and inflammatory processes, response to extracellular stimuli, ion transport and metabolic pathways. We conclude that all three normal source types are suitable for reference kidney control samples, but important differences are to be noted for particular research areas and tissue banking strategies.

IgA deglycosylation to identify glycosylation sites

Project description:In order to provide information on the peptide sequence of the IgA glycopeptides, a proteomics analysis was run on LC-MS/MS data of N-glycosidase F-digested IgA samples, in which the N-glycans had been released. The samples included IgA (isolated) from: 1) the saliva samples from two healthy donors, 2) a pooled-plasma standard from a minimum of 20 human donors (VisuCon-F Frozen Normal Control Plasma; Affinity Biologicals, Ancaster, Canada), 3) 10 μg of a human plasma-derived IgA standard (Lee Biosolutions, Maryland Heights, MO), and 4) a human colostrum-derived SIgA standard (Athens Research and Technology, Athens, GA).

The Tissue-Engineered Human Psoriatic Skin Substitute: A Valuable In Vitro Model to Identify Genes with Altered Expression in Lesional Psoriasis

Project description:Psoriasis is a chronic inflammatory skin disease for which no cure has emerged. Its complex etiology requires the development of an in vitro model representative of the pathology. Various skin substitutes were produced by tissue-engineering using biopsies from normal, healthy donors, or from lesional or non-lesional skin samples from patients with psoriasis, and their gene expression profiles were examined by DNA microarray.

Expression profile of bone marrow HSCs from healthy donors

Project description:mRNA samples from bone marrow CD34+ cells (HSC) from healthy donors after co-culture assays (Control condition, with hMSCs and CD34+ cells from healthy donors; and AML condition, with hMSCs-AML and CD34+ cells from donors) were amplified, labeled and hybridized to the ClariomTM S Array human (Thermo Scientific, USA). Normalization and analysis of microarray data was performed using the Transcriptome Analysis Console (TAC) software (Affymetrix, USA).

mRNA differential expression analysis in a human ex vivo model of chronic wounds

Project description:To study the fibroblast to myofibroblast differentiation in a normal or pathological situation, NHDF (Normal human dermal fibroblast) obtained from two different healthy donors (donors A and B) were either left untreated (T-E-) either treated with TGF-beta alone (T+E-), or with exudate from chronic wounds (T-E+) or both (T+E+). For each different treatment we performed mRNA deep sequencing 3 times : twice with cells from donor A and once with cells from donor B.We focused our study on gene expression profile as a representation of cell fate. We performed mRNA deep sequencing analysis of the 4 different conditions. For each condition, mRNA deep sequencing was performed 3 times : twice with cells from donor A and once with cells from donor B.Comparing the mRNA abundance between the different treatments, we identified 3 lists of genes characterizing the different gene expression states: 171 genes in List I representing the genes differentially expressed during normal fibroblast to myofibroblast differentiation, 409 genes in List II representing the genes differentially expressed upon exudate-only treatment and 1006 genes in List III representing the genes differentially expressed upon the combination of exudate and TGF-beta treatments.

Transcription profiling of multiple normal human tissues (GeneNote)

Project description:The motivation for the present study was to generate a novel data set, GeneNote (Gene Normal Tissue Expression), in order to portray the complete picture of gene expression profiles in healthy human tissues. We used the complete Affymetrix GeneChip HG-U95 set, which includes 62,839 probe-sets, representing a nearly complete set of human genes. The intensity results of two replicates were processed and analyzed to yield the complete transcriptome for the following human tissues: brain, spinal cord, heart, skeletal muscle, bone marrow, thymus, lung, liver, spleen, pancreas, prostate and kidney.

Proteomic Profiling of the Human Tissue and Biological Fluid Proteome

Project description:Here, we performed label-free liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) to profile the normal human proteome. In total, we analyzed 117 samples from 46 histologically normal tissues and organs at autopsy. Our high-resolution MS approach allowed for the quantification of 10,438 unique proteins. In order to expand our coverage of the human proteome, we combined our previously published biological fluid proteomic data from healthy individuals. We considered data from seven biological fluids, including urine, cerebrospinal fluid, synovial fluid, seminal plasma, sweat, cervical vaginal fluid, and nipple aspirate fluid. Overall, we generated tandem mass spectra corresponding to 13,028 unique human protein-coding genes.
