How Metformin Targets Aging Processes

Metformin 's anti- aging effects are likely mediate through a combination of direct andindirect mechanisms. While the drug' s primary target is thought to bo mitochondrial complex I, thee downstream consumeres affect many cellular processes linked to aging. Below are the the moste well-studied mechanisms.

Activation of AMPK

AMP-activated protein kinase (AMPK) is a cellular energy sensor that activate when energy levels are low (high AMP / ATP ratio). Metformin activates AMPK indirectly by hamming ing mitochondrial complex I, leading to an improvee in AMP levels. Once activate, AMPK promotes catobax processes that generate ATP, such ats faty acid oksydation and glucose uptake, which haming anaboid processes like protein syntene liand streage.
