Mechanistic insights into AMP-activated protein kinase-dependent gene expression

Caterina Collodet

AMP-activated protein kinase (AMPK) is a fundamental enzyme that controls energy homeostasis, through orchestrating the cellular response to a reduction in energy availability. Under conditions of cellular energy stress AMPK senses the decrease in ATP leve ...

Identification of novel PCTAIRE-1/CDK16 substrates using a chemical genetic screen

Maria Deak, Kei Sakamoto, Caterina Collodet

PCTAIRE-1 (also known as cyclin-dependent protein kinase (CDK) 16), is a Ser/Thr kinase that has been implicated in many cellular processes, including cell cycle, spermatogenesis, neurite outgrowth, and vesicle trafficking. Most recently, it has been propo ...

CDK4 Phosphorylates AMPK alpha 2 to Inhibit Its Activity and Repress Fatty Acid Oxidation

Anita Nasrallah, Caterina Collodet, Judit Castillo Armengol

The roles of CDK4 in the cell cycle have been extensively studied, but less is known about the mechanisms underlying the metabolic regulation by CDK4. Here, we report that CDK4 promotes anaerobic glycolysis and represses fatty acid oxidation in mouse embry ...

AMPK alpha 1-LDH pathway regulates muscle stem cell self-renewal by controlling metabolic homeostasis

Kei Sakamoto, Laurent Bultot, Lin Yang, Caterina Collodet

Control of stem cell fate to either enter terminal differentiation versus returning to quiescence (self-renewal) is crucial for tissue repair. Here, we showed that AMP-activated protein kinase (AMPK), the master metabolic regulator of the cell, controls mu ...

Benzimidazole derivative small-molecule 991 enhances AMPK activity and glucose uptake induced by AICAR or contraction in skeletal muscle

Maria Deak, Kei Sakamoto, Laurent Bultot, Caterina Collodet

AMP-activated protein kinase (AMPK) plays diverse roles and coordinates complex metabolic pathways for maintenance of energy homeostasis. This could be explained by the fact that AMPK exists as multiple heterotrimer complexes comprising a catalytic alpha-s ...
