Balancing histone methylation activities in psychiatric disorders

Area of Science:

• Neuroscience
• Genetics
• Molecular Biology

Background:

• Epigenetic modifications, including histone lysine methylation, are crucial for regulating gene expression in the brain.
• Alterations in these epigenetic mechanisms are implicated in the pathophysiology of mood and psychosis spectrum disorders, such as depression and schizophrenia.
• Lysine methyltransferases and demethylases play significant roles in the neurobiology of emotion and cognition.

Purpose of the Study:

• To review the role of histone lysine methylation and transcriptional regulation in neurodevelopment.
• To discuss the involvement of epigenetic regulators in neuropsychiatric disorders.
• To explore methyltransferases and demethylases as potential therapeutic targets for these conditions.

Main Methods:

• Literature review of genetic association studies.
• Analysis of animal models.
• Review of research on transcriptional regulation in neurodevelopment and disease.

Main Results:

• Histone lysine methylation alterations contribute to altered brain transcriptomes in mood and psychosis disorders.
• Multiple lysine methyltransferases and demethylases are implicated in the neurobiology of emotion and cognition.
• These epigenetic regulators are involved in both normal and diseased neurodevelopment.

Conclusions:

• Histone lysine methylation and transcriptional regulation are critical in neurodevelopment and neuropsychiatric diseases.
• Dysregulation of specific methyltransferases and demethylases is linked to conditions like depression and schizophrenia.
• Targeting these epigenetic enzymes presents a promising avenue for novel therapeutic interventions in neuropsychiatric disorders.
