Structural Properties of AMP-activated Protein Kinase

Regulation of autophagy by AMP-activated protein kinase/ sirtuin 1 pathway reduces spinal cord neurons damage

Objective(s): AMP-activated protein kinase/sirtuin 1 (AMPK/SIRT1) signaling pathway has been proved to be involved in the regulation of autophagy in various models. The aim of this study was to evaluate the effect of AMPK/SIRT1 pathway on autophagy after spinal cord injury (SCI). Materials and Methods:The SCI model was established in rats in vivo and the primary spinal cord neurons were subject...

Protein kinase C phosphorylates AMP-activated protein kinase α1 Ser487

The key metabolic regulator, AMP-activated protein kinase (AMPK), is reported to be down-regulated in metabolic disorders, but the mechanisms are poorly characterised. Recent studies have identified phosphorylation of the AMPKα1/α2 catalytic subunit isoforms at Ser487/491, respectively, as an inhibitory regulation mechanism. Vascular endothelial growth factor (VEGF) stimulates AMPK and protein ...

AMP-activated protein kinase regulates neuronal polarization

Question: Does the adenosine 5=monophosphate (AMP)-activated protein kinase (AMPK) signaling cascade have a role in neuronal polarization? Background: The differentiation of a single neurite into an axon, which involves increased protein and membrane synthesis as well as the intracellular trafficking of these products, is a metabolically costly process. The AMPK signaling cascade has a major ro...

Amp-activated Protein Kinase – a Ubiquitous Signalling

AMP-activated protein kinase and metabolic control.

AMP-activated protein kinase AMP-activated protein kinase (AMPK AMPK ), a phylogenetically conserved serine/threonine protein kinase, is a major regulator of cellular and whole-body energy homeostasis that coordinates metabolic pathways in order to balance nutrient supply with energy demand. It is now recognized that pharmacological activation of AMPK improves blood glucose homeostasis, lipid p...
