Could Sirtuin Activities Modify ALS Onset and Progression?

Area of Science:

• Neurodegenerative diseases
• Molecular biology
• Genetics

Background:

• Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with complex causes.
• Sirtuins are proteins involved in cellular regulation and have shown potential in neurological disease models.
• Previous research explored Sirtuin manipulation for neuroprotection in ALS, primarily focusing on SOD1 mutations with positive outcomes.

Purpose of the Study:

• To review the existing literature on the role of Sirtuins in amyotrophic lateral sclerosis (ALS).
• To discuss the potential impact of Sirtuin activity on key etiological mechanisms in ALS.
• To highlight the need for evaluating Sirtuins in ALS models beyond SOD1 mutations.

Main Methods:

• Literature review of studies investigating Sirtuins and ALS.
• Analysis of Sirtuin involvement in major ALS pathological pathways.
• Identification of research gaps in current ALS models.

Main Results:

• Sirtuins have been implicated as potential disease-modifying factors in neurological disorders.
• Studies manipulating Sirtuin activity in ALS models (mainly SOD1-mutant) yielded largely positive neuroprotective and survival benefits.
• The precise mechanisms by which Sirtuins influence ALS pathogenesis require further elucidation.

Conclusions:

• Sirtuin modulation presents a potential therapeutic avenue for amyotrophic lateral sclerosis (ALS).
• Further research is crucial to assess Sirtuin benefits in ALS models carrying TDP-43, FUS, and C9orf72 mutations.
• Expanding research beyond SOD1 is essential for a comprehensive understanding of Sirtuins' role in ALS progression.
