Project description:Genome-wide patterns of DNA methylation were quantified using the Illumina Infinium HumanMethylation450K BeadChip (“450K array”) in DNA samples isolated from blood for schizophrenia cases, first episode psychosis patients and controls. These samples were profiled as part of a wider study where they were meta-analysed with other cohorts.

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.
