The Hallmarks of Aging: Deregulated Nutrient Sensing

Posted by in category: life extension

As part of our ongoing series covering the hallmarks of aging, we are taking a look at deregulated nutrient sensing today and how these four pathways regulate metabolism and influence aging.

To understand studies on nutrient sensing in the context of aging, let’s introduce four key protein groups. In this post, we’ll explore the pathways they help control and how they affect aging. These key proteins are IGF-1, mTOR, sirtuins, and AMPK[2]. We call these proteins “nutrient sensing” because nutrient levels influence their activity[2].
