Abstract
En 中文
This study employed a multi-omics approach to investigate the molecular and functional underpinnings of schizophrenia by integrating blood transcriptomic profiles, neuroimaging-derived brain phenotypes, and clinical symptomatology. RNA sequencing of blood samples from 43 patients with schizophrenia and 60 healthy controls identified 994 differentially expressed genes (DEGs), the vast majority of which were downregulated (n = 921, |FC| > 1.5, P < 0.05), with enrichment in pathways related to neuronal development and inflammation. Concurrent neuroimaging analyses revealed altered functional activation in key brain regions, including the prefrontal and anterior cingulate cortices. A Partial Least Squares correlation analysis demonstrated significant cross-modal relationships among gene expression, neuroimaging patterns, and clinical presentation. Furthermore, we identified six genes—GRK2, KLF3, TAOK2, ARFGAP45, AP1M1, and GPAT2—that were shared across gene sets associated with both brain function and clinical symptoms, suggesting a common transcriptional basis for these features of schizophrenia. Collectively, these findings provide novel insights into the integrated molecular and functional changes in schizophrenia, highlighting the value of a comprehensive multi-omics strategy to decipher its pathophysiology and potentially inform improved diagnostic and therapeutic strategies.
