Disrupted-in-schizophrenia 1 (DISC1) protein dysfunction contributes to mental illnesses. This study proposes classifying DISC1-related brain disorders as a single entity, DISCopathies, for targeted therapies.
Area of Science:
- Neuroscience
- Molecular Biology
- Psychiatry
Background:
- Disrupted-in-schizophrenia 1 (DISC1) is implicated in the pathogenesis of schizophrenia and affective disorders.
- DISC1 regulates crucial brain functions like corticogenesis, synapse integrity, and neurogenesis.
- DISC1 acts as a molecular facilitator, interacting with protein complexes and signaling molecules.
Purpose of the Study:
- To propose a unified classification for brain disorders associated with DISC1 dysfunction.
- To establish DISCopathies as a distinct disease entity.
Main Methods:
- Review of DISC1's cellular functions and interactions.
- Analysis of DISC1's role in protein conformational disorders.
- Pathophysiological characterization of DISC1-related brain conditions.
Main Results:
- DISC1 protein can oligomerize and form dysfunctional, insoluble complexes.
- These misassembled DISC1 complexes are characteristic of protein conformational disorders.
- Dysfunctional DISC1 underlies various brain disorders.
Conclusions:
- Brain disorders linked to DISC1 dysfunction share a common pathophysiological basis.
- Classifying these as DISCopathies facilitates the development of targeted (pharmaco)therapies.
- DISCopathies represent a novel disease entity for mental health research.
