The Multiomics Landscape of Plasma Exosomes in First-Episode Drug-Naïve of Schizophrenia

ABSTRACT: This research project aims to explore the multiomics landscape of plasma exosomes in patients with schizophrenia. Our study involves 10 first-episode drug-naïve schizophrenia patients and 10 healthy controls. By comparing the exosomes derived from these two groups, we hope to uncover biomarkers associated with schizophrenia and potential pathogenic mechanisms. The project seeks to provide new insights for the early diagnosis and intervention of schizophrenia.

BACKGROUND: Schizophrenia (SZ) is a debilitating mental illness with uncertain etiology and challenges in early diagnosis and treatment outcomes. For the first time, we applied a multiomics techniques to explore plasma exosomal markers of SZ and underlying molecular mechanisms. METHODS: Exosomes were separated and identified from ten drug-naive first-episode SZ patients and ten healthy controls. Then small RNA-seq and high-performance liquid chromatography-tandem mass spectrometry technology wer ...[more]

Nanostring analysis of exosomal miRNA from plasma of head and neck cancer (HNSCC) patients

Project description:Exosomes were isolated from plasma of n = 12 healthy donors (HD) and n = 16 head and neck cancer (HNSCC) patients. miRNA profiling of exosomes was performed using nCounter SPRINT system. miRNAs being predicted to target EMT-related genes (CDH1, VIM, TWIST1 and SNAI1/2) were selected and compared between HD and HNSCC patients.

The Multiomics Landscape of Plasma Exosomes in First-Episode Drug-Naïve of Schizophrenia

Project description:Background: Schizophrenia (SZ) is a debilitating mental illness with uncertain etiology and challenges in early diagnosis and treatment outcomes. For the first time, we applied a multiomics techniques to explore plasma exosomal markers of SZ and underlying molecular mechanisms. Methods: Exosomes were separated and identified from ten drug-naive first-episode SZ patients and ten healthy controls. Then small RNA-seq and high-performance liquid chromatography-tandem mass spectrometry technology were used to detect the profiles of microRNAs (miRNAs) and proteomics, respectively. The integrative multiomics analysis was further performed. Results: A total of 167 differentially expressed miRNAs (DE miRNAs) were identiﬁed in plasma exosomes from drug-naive first-episode SZ patients. The potential target genes of DE miRNAs were predicted, and GO and KEGG enrichment analysis showed that they were associated with RNA catabolic process, proteasome-mediated ubiquitin-dependent protein catabolic process, etc. Proteomic analysis identified 274 differentially expressed proteins (DEPs), and DEPs were mainly enriched in immune response and some signaling pathways. The combination of Top 10 DE miRNAs/ DEPs both had good values to diagnose SZ. Importantly, miRNA-protein ceRNA networks were constructed by integrating multiomics, one consisting of 21 downregulated DE miRNAs and 21 upregulated DEPs and the other consisting of 64 upregulated DE miRNAs and 86 downregulated DEPs in SZ patients. Conclusions: Our study for the ﬁrst time describes the multiomics landscape of plasma exosomes in first-episode drug-naïve of SZ, and provides novel insights into the molecular alterations of SZ. These findings hold promise for advancing diagnostic and therapeutic strategies in SZ management.

3' mRNA sequencing of piglet blood compartments

Project description:This study describes the transcriptome of distinct blood compartments derived from whole blood collected from piglets. The dataset includes RNA-seq data from 20 samples representing five blood compartments: whole blood, serum, plasma, serum-derived exosomes, and plasma-derived exosomes. From each whole blood sample, the different fractions were carefully prepared using optimized and compartment-specific protocols. RNA-seq libraries were prepared using the LEXOGEN QuantSeq 3′ mRNA-Seq V2 Library Prep Kit with protocol adaptations for whole blood, plasma, serum, and exosome samples. Sequencing was performed on the Illumina NextSeq2000 platform in SR75. The 20 raw demultiplexed FASTQ files are part of this accession. Bioinformatic pre-processing was conducted using the Nextflow nf-core/rnaseq pipeline to ensure high sequence quality and robust transcriptome assembly and quantification. Each file contains raw sequencing reads along with base quality scores. Bioinformatic and statistical analyses explored the variability in gene detection and gene expression variability according to the five blood compartments.

miRNA-seq of exosomes derived from bone-metastatic lung cancer cells

Project description:This study aimed to identify miRNAs enriched in exosomes that promote osteolytic bone metastasis. We performed miRNA-seq directly on exosomes purified from the culture supernatants of either non-metastatic (NC-LLC) or bone-metastatic (BM-LLC) Lewis lung carcinoma cells. The goal was to profile the miRNA cargo of these tumor-derived exosomes and identify key regulators of intercellular communication. Integrated analysis with mRNA sequencing data from recipient macrophages identified exosomal miR-484 as a critical driver of osteoclast differentiation and bone metastasis.

Small RNA-Seq of plasma-derived exosomes from Acute Respiratory Distress Syndrome patients and healthy subjects

Project description:Despite a significant progress in the treatment of Acute Respiratory Distress Syndrome (ARDS), our ability to identify early patients and predict outcome remains limited. In this study, we aimed to characterize small RNA content of plasma exosomes from ARDS patients in order to identify potential diagnostic biomarkers of the disease. For the first time, we profiled miRNA expression levels in plasma-derived exosomes from ARDS patients (n=8) compared to healthy subjects (n=10) by small RNA-seq. It allowed us to identify 12 exosomal miRNAs differentially expressed in ARDS context (padj<0.05).

MicroRNA profile of cells and exosomes

Project description:The goal of this study is to report that breast cancer associated exosomes contain microRNAs (miRNAs) associated with the RISC Loading Complex (RLC) and display cell-independent capacity to process precursor microRNAs (pre-miRNAs) into mature miRNAs. Pre-miRNAs, along with Dicer, AGO2, and TRBP, are present in exosomes of cancer cells. CD43 mediates the accumulation of Dicer specifically in cancer exosomes. Cancer exosomes mediate an efficient and rapid silencing of mRNAs to reprogram the target cell transcriptome. Exosomes derived from cells and sera of patients with breast cancer instigate non-tumorigenic epithelial cells to form tumors in a Dicer-dependent manner. These findings offer opportunities for the development of exosomes based biomarkers and therapies. Exosomes from cancer cells and non-tumorigenic cells were isolated using established ultracentrifugation methods. The global miRNA content of cancer exosomes and normosomes was investigated. Profiling of cells themselves was also used as a control. Exosomes with Dicer down regulation (MCF10AshDicer and MDA-MB-231shDicer exosomes), as well as MDA-MB-231 exosomes that contain a Dicer antibody inside were used to study the function Dicer protein in the microRNA biogenesis in exosomes.
