Sirtuin functions and modulation: from chemistry to the clinic

Area of Science:

• Biochemistry and Molecular Biology
• Epigenetics
• Enzymology

Background:

• Sirtuins are NAD(+)-dependent histone deacetylases involved in critical cellular functions.
• They regulate pathways including cell survival, metabolism, DNA repair, and caloric restriction.
• Dysregulation of sirtuins is implicated in various human diseases.

Purpose of the Study:

• To review the diverse biological roles and mechanisms of action of the seven sirtuin family members.
• To highlight the significance of sirtuins as therapeutic targets for human pathologies.
• To discuss the development of small molecules that modulate sirtuin activity.

Main Methods:

• Literature review of sirtuin research.
• Analysis of sirtuin functions in prokaryotes and eukaryotes.
• Examination of sirtuin inhibitors and activators.

Main Results:

• Sirtuins play multifaceted roles in cellular processes and metabolic regulation.
• The seven sirtuins are implicated in neurodegenerative diseases, cardiovascular diseases, and cancer.
• Sirtuin modulators are emerging as key epigenetic regulators.

Conclusions:

• Sirtuins represent promising therapeutic targets for a range of human diseases.
• Further research into sirtuin modulators can lead to novel treatment strategies.
• Understanding sirtuin biology is essential for advancing epigenetic therapies.
