Neurodegeneration the RNA way

Area of Science:

• Neuroscience
• Molecular Biology
• Genetics

Background:

• RNA molecules are essential for neuronal function and differentiation.
• Dysregulation of RNA pathways is increasingly implicated in neurodegenerative diseases.
• This review focuses on the multifaceted roles of RNA in neurodegeneration.

Purpose of the Study:

• To provide a comprehensive overview of RNA's involvement in neurodegenerative disorders.
• To highlight key mechanisms linking RNA processing defects to disease pathogenesis.
• To discuss emerging concepts such as RNAopathies and RNA binding proteinopathies.

Main Methods:

• Literature review and synthesis of current research on RNA and neurodegeneration.
• Categorization of neurodegenerative mechanisms related to RNA.
• Discussion of specific examples including repeat expansions and RNA binding protein aggregation.

Main Results:

• Non-coding repeat expansions (RNAopathies) contribute to pathogenesis via diverse mechanisms.
• RNA binding proteinopathies involve the mislocalization and aggregation of proteins like TDP-43 and FUS.
• Alterations in both short and long non-coding RNAs are implicated in neurodegenerative illnesses.

Conclusions:

• RNA processing and function are critical in both normal neuronal activity and the development of neurodegeneration.
• Understanding RNA's role offers new avenues for diagnosing and treating neurodegenerative diseases.
• Further research into RNAopathies and RNA binding proteinopathies is crucial for advancing the field.
