Research progress of RNA pseudouridine modification in nervous system

Area of Science:

• Biochemistry
• Molecular Biology
• Neuroscience

Background:

• Pseudouridine (Ψ) is a critical RNA modification regulating gene expression and RNA processing.
• Pseudouridine synthases (PUS) catalyze Ψ modification, recognizing specific RNA sequences and structures.
• Dysregulation of PUS enzymes is linked to various neurological disorders.

Purpose of the Study:

• To review the role of Ψ modification in RNA structure and function.
• To explore the association between PUS enzymes and nervous system disorders.
• To highlight the need for understanding PUS mechanisms in neurons for therapeutic development.

Main Methods:

• Comprehensive literature review of PUS enzymes and their roles in RNA modification.
• Analysis of the link between PUS mutations/dysfunction and neurological diseases.
• Elucidation of Ψ's impact on RNA structure and function.

Main Results:

• Ψ modification strengthens RNA structures, influencing RNA function.
• PUS1, PUS3, PUS7, PUS10, and dyskerin PUS1 are associated with neurodevelopmental disorders, tumors, and myopathies.
• The precise mechanisms of PUS action in neurons remain largely unknown.

Conclusions:

• Ψ modification is integral to RNA biology and nervous system function.
• Further research into PUS mechanisms in neurons is essential for developing Ψ-based therapeutics for neurological conditions.
• Understanding these mechanisms will unlock new avenues for treating complex nervous system diseases.
