Epigenetics of neurological diseases

Area of Science:

• Molecular Biology
• Genetics
• Neuroscience

Background:

• Epigenetic processes, such as DNA methylation and histone modifications, regulate higher-order DNA structure and gene expression.
• Aberrant epigenetic mechanisms are implicated in various diseases, notably cancer.
• Recent findings reveal genome-wide epigenetic changes contributing to neurological disorders, expanding beyond discrete DNA sequences previously associated with rare genetic syndromes.

Purpose of the Study:

• To describe epigenetic alterations observed in diverse neurological disorders.
• To explore the impact of these epigenetic changes on the development of novel therapeutic approaches.

Main Methods:

• Review of current literature on epigenetic alterations in neurological diseases.
• Analysis of genome-wide epigenetic changes and their functional consequences.
• Discussion of therapeutic strategies targeting epigenetic modifications.

Main Results:

• Epigenetic dysregulation is a common feature across a spectrum of neurological disorders, including Parkinson's disease, Huntington's disease, epilepsy, and multiple sclerosis.
• Genome-wide epigenetic alterations play a crucial role in the pathogenesis of both developmental and degenerative neurological conditions.
• These findings highlight the potential for epigenetic modifications as therapeutic targets.

Conclusions:

• Epigenetic alterations are fundamental to the pathophysiology of numerous neurological disorders.
• Targeting epigenetic mechanisms presents a promising avenue for developing innovative therapies for complex neurological conditions.
