* '''Yeast (Saccharomyces cerevisiae):''' The discovery of Sir2 in yeast laid the foundation for sirtuin research. Yeast studies showed that increasing Sir2 activity extended replicative lifespan, sparking interest in sirtuins' potential as longevity regulators. | * '''[[Yeast (Saccharomyces Cerevisiae)|Yeast (Saccharomyces cerevisiae)]]:''' The discovery of Sir2 in yeast laid the foundation for sirtuin research.

* '''Nematode Worms (Caenorhabditis elegans):''' Studies in nematode worms revealed that overexpression of sirtuin genes could extend both mean and maximum lifespan. This finding highlighted the conservation of sirtuin-mediated longevity across species. | * '''[[Nematode Worms (Caenorhabditis elegans)]]:''' Studies in nematode worms revealed that overexpression of sirtuin genes could extend both mean and maximum lifespan.

Understanding the link between sirtuins and longevity is a critical step in unlocking the potential of these proteins for promoting a longer and healthier life. In the following sections, we will explore strategies to activate sirtuins, the health benefits they offer, and the controversies and challenges in sirtuin research. | Understanding the link between sirtuins and longevity is a critical step in unlocking the potential of these proteins for promoting a longer and healthier life.
