Biological Causes of Schizophrenia

Biological Causes of Schizophrenia

Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin studies.

Area of Science:

Neuroscience
Computational Biology
Biochemistry

Background:

Schizophrenia (SCZ) presents complex, heterogeneous molecular pathology poorly understood by single-omics.
Conventional methods limit biomarker discovery and mechanistic insights into SCZ.

Purpose of the Study:

To apply an AI-driven multi-omics framework to dissect SCZ pathophysiology.
To enhance SCZ classification and identify key molecular discriminators using integrated data.

Main Methods:

Utilized an AI multi-omics framework integrating plasma proteomics, post-translational modifications (PTMs), and metabolomics.
Compared 17 machine learning models for SCZ classification performance.
Employed interpretable feature prioritization and functional enrichment analyses.

Main Results:

Multi-omics integration significantly improved SCZ classification (AUC 0.9727) compared to proteomics alone (AUC 0.9636).
Identified carbamylation and oxidation PTMs, particularly on immunoglobulin and coagulation factors, as key discriminators.
Enriched pathways included complement activation, platelet signaling, and gut microbiota metabolism.
Protein networks implicated coagulation factors (F2, F10, PLG) and complement regulators (CFI, C9) as central hubs.

Conclusions:

Immune-thrombotic dysregulation is implicated as a critical component of SCZ pathology.
PTMs of immune proteins serve as quantifiable indicators for SCZ.
The study provides a robust computational strategy for multi-omics integration in psychiatric research, identifying potential biomarkers.
