Schizophrenia Proteome Research


ABSTRACT: Despite of multiple systematic studies of schizophrenia pathogenesis, reconstruction of the mechanism established on proteomics, metabolomics, and genome-wide significant loci is still a challenging task. We suggested that advanced data for quantitative proteomics, metabolomics, and genome-wide association study (GWAS) may enhance the current evidence and fundamental knowledge about molecular pathogenesis of schizophrenia. Liquide chromatography and ultra-high-resolution mass-spectrometry were utilized for proteomic and metabolomic assay, and high throughput genotyping for the GWAS study. Proteomic and metabolomic results were quantitatively evaluated and overlayed on the GWAS data. After statistical analysis using R-package, the resulting features were associated in a multilayer mode with adjusted biological processes in a reconstructed unified map of molecular events. We have identified 20 DFE proteins that were validated on an independent cohort of patients that are significant for schizophrenia, including ALS, A1AG1, PEDF, VTDB, CERU, APOB, APOH, FASN, GPX3, etc. Almost half of them are new for schizophrenia. The metabolomic survey revealed 18 compounds most of which were the part transformation of tyrosine and steroids with the incline to androgens (androsterone sulfate, thyroliberin, thyroxine, dihydrotestosterone, androstenedione, cholesterol sulfate, metanephrine, dopaquinone, etc.) which were extracted as group-specific determinants that permits to isolate patients with schizophrenia. The GWAS assay revealed 52 loci were integrated into proteome-metabolome data as significantly implicated in schizophrenia. We integrated three layers of omics science (proteomics, metabolomics and GWAS) and quantitative analysis utilized systematic approach to reconstruct the proposed map of molecular events associated with the considered psychopathology. The resulting interplay between different layers emphasized strict implication of lipids metabolism, oxidative stress, imbalance in steroidogenesis and associated impartments of thyroid hormones and sex hormones interconnection. The proposed interplay map can give opportunity in the understanding how the regulation of distinct metabolic axis is achieved and what happens in proteome arrangements to produce a schizophrenia-specific pattern of pathology condition.
