A multi-omics atlas of common wheat

ABSTRACT: Integration of multi-omics data can provide information on biomolecules from different layers to illustrate the complex biology systematically. Here, we built the first global quantitative atlas containing transcriptomes, proteomes, phospho-proteomes and acetyl-proteomes of 20 tissues in common wheat. We identified 132,570 transcripts, 32,256 proteins, 69,364 phosphorylation sites, and 34,974 acetylation sites across wheat development stages. Our data demonstrated that homoeolog expression bias exists divergence at different omics layers. Regulatory networks dissected critical proteins or genes controlling important biology processes. Four wheat trait-gene families refer to timely flowering, disease resistance, starch biosynthesis-related genes, and seed storage proteins were used as examples to verify our data and shed novel inlight on the importance of post-translational modifications in wheat previously unknown. Importantly, a novel Fusarium crown rot (FCR) resistant gene delta-1-pyrroline-5-carboxylate synthase (TaP5CS1) was identified by FCR-responsive multi-omics techniques. We found that TaP5CS1 confers FCR tolerance via increased proline content and is regulated by histone deacetylase 9 (TaHDA9). Our multi-omics atlas data will accelerate function and mechanism studies of important traits in wheat.

Multi-omics profiling of patients with primary Sjogren's syndrome

Project description:Multi-omics study was conducted to elucidate the crucial molecular mechanisms of primary Sjögren’s syndrome (SS) pathology. We generated multiple data set from well-defined patients with SS, which includes whole-blood transcriptomes, serum proteomes and peripheral immunophenotyping. Based on our newly generated data, we performed an extensive bioinformatic investigation. Our integrative analysis identified SS gene signatures (SGS) dysregulated in widespread omics layers, including epigenomes, mRNAs and proteins. SGS predominantly involved the interferon signature and ADAMs substrates. Besides, SGS was significantly overlapped with SS-causing genes indicated by a genome-wide association study and expression trait loci analyses. Combining the molecular signatures with immunophenotypic profiles revealed that cytotoxic CD8 T cells were associated with SGS. Further, we observed the activation of SGS in cytotoxic CD8 T cells isolated from patients with SS. Our multi-omics investigation identified gene signatures deeply associated with SS pathology and showed the involvement of cytotoxic CD8 T cells. These integrative relations across multiple layers will facilitate our understanding of SS at the system level. Proteomics and FACS data will be found in Synapse. https://www.synapse.org/#!Synapse:syn8483276

Multi-omics atlas of combinatorial abiotic stress responses in wheat

Project description:We present a transcriptomic atlas of abiotic stress tolerance in wheat. We employed a systems biology approach to study physiological, metabolomic and transcriptomic responses associated with heat, drought, salinity and their possible combinations. Our objectives were to (1) rank stress treatments based on the overall physiological and growth impacts, (2) identify the core sets of genes common to a particular stress type, (3) examine pathways that are uniquely expressed in the various stress combinations, (4) detect associations between phenotypic and transcriptomic responses, (5) suggest possible transcription factors for further characterization and use in improving wheat performance in multi-stress environments.

Mouse tissue atlas

Project description:We used state of the art mass spectrometry (MS) and RNA sequencing (RNA-Seq) to provide the first integrated proteomic, phosphoproteomic and transcriptomic atlas of the animal model Mus musculu . We measured 66 murine pancreatic ductal adenocarcinoma cell lines (66 proteomes and 66 phosphoproteome) and 41 healthy tissues (41 proteomes, 41 phosphoproteome, and 29 transcriptomes). The employed MS-based and bioinformatics strategy identified >17,000 proteins and >50,000 phosphorylation sites, providing expression evidence for ~76% of the 22,437 protein-coding genes reported in UniProtKB. The RNA-Seq strategy resulted in the quantification of 21,261 unique gene that were expressed in at least one of the 29 sequenced tissue.

Acute depletion of CTCF rewires genome-wide chromatin accessibility

Project description:The transcription factor CTCF appears indispensable in defining topologically associated domain boundaries and maintaining chromatin loop structures within these domains, supported by numerous functional studies. However, acute depletion of CTCF globally reduces chromatin interactions but does not significantly alter transcription. Here we systematically integrated multi-omics data including ATAC-seq, RNA-seq, WGBS, Hi-C, Cut&Run, CRISPR-Cas9 survival dropout screening, time-solved deep proteomic and phosphoproteomic analyses in cells carrying auxin-induced degron at endogenous CTCF locus. Acute CTCF protein degradation markedly rewired genome-wide chromatin accessibility. Increased accessible chromatin regions were largely located adjacent to CTCF-binding sites at promoter regions and insulator sites and were associated with enhanced transcription of nearby genes. In addition, we used CTCF-associated multi-omics data to establish a combinatorial data analysis pipeline to discover CTCF co-regulatory partners in regulating downstream gene expression. We successfully identified 40 candidates, including multiple established partners (i.e., MYC) supported by all layers of evidence. Interestingly, many CTCF co-regulators (e.g., YY1, ZBTB7A) that have evident alterations of respective downstream gene expression do not show changes at their expression levels across the multi-omics measurements upon acute CTCF loss, highlighting the strength of our system to discover hidden co-regulatory partners associated with CTCF-mediated transcription. This study highlights CTCF loss rewires genome-wide chromatin accessibility, which plays a critical role in transcriptional regulation

Integrated Analysis of Small RNA, Transcriptome, and Degradome Sequencing Reveals the Water-Deficit and Heat Stress Response Network in Durum Wheat

Project description:Water-deficit and heat stress negatively impact crop production. Mechanisms underlying the response of durum wheat to such stresses are not well understood. With the new durum wheat genome assembly, we conducted the first multi-omics analysis with next-generation sequencing, providing a comprehensive description of the durum wheat small RNAome (sRNAome), mRNA transcriptome, and degradome. Single and combined water-deficit and heat stress were applied to stress-tolerant and -sensitive Australian genotypes to study their response at multiple time-points during reproduction. Analysis of 120 sRNA libraries identified 523 microRNAs (miRNAs), of which 55 were novel. Differentially expressed miRNAs (DEMs) were identified that had significantly altered expression subject to stress type, genotype, and time-point. Transcriptome sequencing identified 49,436 genes, with differentially expressed genes (DEGs) linked to processes associated with hormone homeostasis, photosynthesis, and signaling. With the first durum wheat degradome report, over 100,000 transcript target sites were characterized, and new miRNA-mRNA regulatory pairs were discovered. Integrated omics analysis identified key miRNA-mRNA modules (particularly, novel pairs of miRNAs and transcription factors) with antagonistic regulatory patterns subject to different stresses. GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) enrichment analysis revealed significant roles in plant growth and stress adaptation. Our research provides novel and fundamental knowledge, at the whole-genome level, for transcriptional and post-transcriptional stress regulation in durum wheat.

Proteomes from small sizes of paired normal and glioblastoma patient tissues

Project description:Although multi-omics studies of glioblastoma (GBM) have improved understanding of its biology nature and accelerated targeted therapy, data for paired adjacent normal tissues (NAT) remains limited. Here, we report proteomes from 3 paired of tumor tissues and NATs of glioblastoma (GBM) patients using liquid chromatography with tandem mass spectrometry (LC-MS/MS)-based label-free quantification. This dataset provides a resource of paired GBM and normal tissues to identify novel tumor-specific oncogenes or tumor-suppressor genes.
