Sirtuins are central players in the regulation of aging processes, and their activities are closely tied to the overall health and longevity of an organism. At the heart of their anti-aging effects lies their ability to modulate various cellular pathways and maintain cellular homeostasis. This section explores the intricate mechanisms through which sirtuins influence the aging process. | Sirtuins are central players in the regulation of aging processes, and their activities are closely tied to the overall health and longevity of an organism.

* '''Epigenetic Regulation:''' Sirtuins play a pivotal role in modifying epigenetic marks on DNA and histones. By deacetylating these molecular markers, sirtuins can silence or activate specific genes, influencing cellular functions and ultimately impacting the aging process. | * '''[[Epigenetic Alterations|Epigenetic Regulation]]:''' Sirtuins play a pivotal role in modifying epigenetic marks on DNA and histones.

* '''Inflammation and Oxidative Stress:''' Sirtuins are known to suppress chronic inflammation and reduce oxidative stress within cells. These processes are closely linked to aging and age-related diseases, and sirtuins' ability to mitigate them contributes to their role in longevity. | * '''Inflammation and [[Oxidative Stress]]:''' Sirtuins are known to suppress chronic inflammation and reduce oxidative stress within cells.

* '''Autophagy and Cellular Cleanup:''' Sirtuins promote autophagy, a cellular process responsible for removing damaged or dysfunctional cellular components. This "cellular cleanup" mechanism helps maintain cellular health and delay the aging process. | * '''[[Autophagy]] and Cellular Cleanup:''' Sirtuins promote autophagy, a cellular process responsible for removing damaged or dysfunctional cellular components.
