DISC1: a key lead in studying cortical development and associated brain disorders

Area of Science:

• Neuroscience
• Developmental Biology
• Psychiatry

Background:

• Disrupted-In-Schizophrenia 1 (DISC1) is a key gene implicated in major mental illnesses like schizophrenia.
• Extensive research has focused on DISC1's role in psychiatric disorders, leading to numerous review articles.
• This article shifts focus from a general overview to DISC1's specific role in cortical development.

Purpose of the Study:

• To elucidate the utility of DISC1 in studying cortical development.
• To associate DISC1 function with a spectrum of developmental brain disorders.
• To highlight DISC1 as a potential therapeutic target for abnormal cortical development.

Main Methods:

• Literature review focusing on DISC1's function in corticogenesis.
• Analysis of DISC1's involvement in cell-autonomous and cell-non-autonomous developmental mechanisms.
• Examination of DISC1's role in host responses to environmental factors during brain development.

Main Results:

• DISC1 plays a significant role in orchestrating the complex processes of corticogenesis.
• DISC1's function is integral to both intrinsic cellular processes and responses to external influences during cortical development.
• Understanding DISC1's multifaceted roles provides insights into various developmental brain disorders.

Conclusions:

• DISC1 is a critical factor in normal cortical development.
• Dysregulation of DISC1 contributes to a range of developmental brain disorders.
• Targeting DISC1 pathways offers potential therapeutic strategies for conditions arising from abnormal cortical development.
