AMP-activated protein kinase and its downstream transcriptional pathways

Johan Auwerx, Carlos Canto Alvarez

The AMP-activated protein kinase (AMPK) is a key regulator of catabolic versus anabolic processes. Its properties as an energy sensor allow it to couple the energy status of the cell to the metabolic environment. These adaptations not only take place throu ...

Clking on PGC-1alpha to inhibit gluconeogenesis

Johan Auwerx, Carlos Canto Alvarez

The link between Akt activation and gluconeogenic repression remains unclear, despite many years of investigation and remarkable progress. Rodgers and colleagues now introduce us to the Clk2 kinase, an Akt substrate that can directly phosphorylate and inhi ...

Interdependence of AMPK and SIRT1 for Metabolic Adaptation to Fasting and Exercise in Skeletal Muscle

Johan Auwerx, Carlos Canto Alvarez, Chikage Mataki

During fasting and after exercise, skeletal muscle efficiently switches from carbohydrate to lipid as the main energy source to preserve glycogen stores and blood glucose levels for glucose-dependent tissues. Skeletal muscle cells sense this limitation in ...

Caloric restriction, SIRT1 and longevity

Johan Auwerx, Carlos Canto Alvarez

More than 70 years after its initial report, caloric restriction stands strong as the most consistent non- pharmacological intervention increasing lifespan and protecting against metabolic disease. Among the different mechanisms by which caloric restrictio ...

AMPK regulates energy expenditure by modulating NAD(+) metabolism and SIRT1 activity

Johan Auwerx, Lilia Noriega Lopez, Carlos Canto Alvarez

AMP-activated protein kinase (AMPK) is a metabolic fuel gauge conserved along the evolutionary scale in eukaryotes that senses changes in the intracellular AMP/ATP ratio. Recent evidence indicated an important role for AMPK in the therapeutic benefits of m ...

PGC-1alpha, SIRT1 and AMPK, an energy sensing network that controls energy expenditure

Johan Auwerx, Carlos Canto Alvarez

PURPOSE OF REVIEW: Peroxisome proliferator-activated receptor gamma coactivator-1-alpha (PGC-1alpha) has been extensively described as a master regulator of mitochondrial biogenesis. However, PGC-1alpha activity is not constant and can be finely tuned in r ...

Glucose restriction: longevity SIRTainly, but without building muscle?

Johan Auwerx, Carlos Canto Alvarez

The two metabolic sensors AMPK and SIRT1 take center stage as Fulco et al. reveal, in this issue of Developmental Cell, the signaling mechanism by which low glucose prevents the correct development of the myogenic program. These observations may hold some ...
