Project description:Purpose: The present study is aiming to understand transcriptome changes during psoriatic changes using high-throughput sequencing and thereby comprehensively assess the diseases and guide future research directions. Methods: Clinical psoriatic samples, including psoriatic lesions and their adjacent normal skin samples, and the surgical derived skins from healthy individuals as comparative controls were collected and analysed of their RNA expression profile using Illumina HiSeq 4000. raw sequencing reads were processed and pre-qualified using Trimmomatic and Fragments Per kb Per Million Reads (FPKM) method was used to calculate the abundance of each transcript followed by Negative Binomial Distribution tests to identify significant differences in each comparison. Results: Total reads for mRNAs, lncRNAs and miRNAs was 108,552, 105,136 and 2762, respectively, including 649 novel lncRNAs and 905 novel miRNAs. 5383 DE_mRNAs, 1201 DE_lncRNAs and 80 DE_miRNAs were identified in the comparison of the psoriasis lesions-adjacent normal group (PN) vs. healthy control-derived normal skin group (NN; PN vs. NN). A total of 9513 DE_mRNAs, 1940 DE_lncRNAs and 251 DE_miRNAs were identified in the psoriasis lesion group (PS) vs. NN comparison (PS vs. NN), and 4946 DE_mRNAs, 1559 DE_lncRNAs and 92 DE_miRNAs were identified in the PS vs. PN comparison. Conclusions: We identified numerous differentially expressed RNAs, including mRNAs, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs). Our results reveal transcriptomic changes, expand our mechanistic understanding of psoriasis, and may lead to new directions for psoriasis research.

Project description:A new high-density oligonucleotide array of the human transcriptome (GG-H array) has been developed for high-throughput and cost-effective analyses in clinical studies. This array allows comprehensive examination of gene expression and genome-wide identification of alternative splicing, as well as detection of coding SNPs and non-coding transcripts. The GG-H array was validated using samples from multiple independent preparations of human liver and muscle, and compared with results obtained from mRNA sequencing analysis. The GG-H array is highly reproducible in estimating gene and exon abundance, and is sensitive in detecting expression changes and alternative splicing. This array has been implemented in a multi-center clinical program and has generated high quality, reproducible data. When current cost, as well as sample and time requirements for sequencing are considered in the context of a required throughput of hundreds of samples per week for a clinical trial, the array provides a high-throughput and cost effective platform for clinical genomic studies.

Project description:Transcriptome analysis of Psoriasis
| PRJNA472389 | ENA
Project description:Psoriasis was found to ameliorate multiple sclerosis (MS) outcomes when it MS onset. However, the molecular basis for this observation remains unclear. Herein, we compared the blood mononuclear cell transcriptome of psoriasis and MS comorbide (P/MS) patients with that of patients with either psoriasis or MS to understand the clinical observation.

Project description:We report the high-throughput profiling of tissue biopsy from psoriasis skin before the start of NB-UVB therapy and after the last treatment session.RNA sequencing (RNA-Seq) was conducted to assay the transcriptomes and identify differentially expressed transcripts enriched in major pathway analysis. Our results support that clinically effective NB-UVB therapy is based on suppression of a broad range of inflammatory signaling pathways, gene expression of inflammatory cytokines, and increased the expression of anti-inflammatory signaling pathways in psoriatic skin.

Project description:Clinical proteomics holds the promise to accelerate the discovery of disease biomarkers, as well as to predict disease trajectories. Here we present a new platform for high-throughput plasma and serum proteomics, which combines an automated sample preparation workflow, robust high-flow liquid chromatography, and an optimized SWATH-MS acquisition scheme as well as data processing workflow. The process requires as little as 5uL serum or plasma and makes use of fast 5-minute chromatographic gradients. The dataset shows the robustness and precision of the workflow and consists of commercial plasma and serum samples that were distributed in 4 different 96 well plates and injected within a sample series of 417 serum injections. Further, the dataset includes of injections of a single sample (pooled from 32 prepared commercial serum samples) every 10 injections.
