* '''[[Yeast (Saccharomyces Cerevisiae | * '''[[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. | ||
* '''[[Nematode Worms (Caenorhabditis | * '''[[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. | ||
* '''[[ | * '''[[Mice (Mus Musculus)]]:''' Genetically engineered mice with enhanced sirtuin activity have displayed improved metabolic health, resistance to age-related diseases, and increased lifespan, providing compelling evidence for sirtuins' role in mammalian aging. | ||
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.
