AMP-activated protein kinase and the regulation of autophagic proteolysis.
Interruption of mTOR-dependent signaling by rapamycin is known to stimulate autophagy, both in mammalian cells and in yeast. Because activation of AMPK also inhibits mTOR-dependent signaling one would expect stimulation of autophagy by AMPK activation. According to the literature, this is true for yeast but, unexpectedly, not for mammalian cells on the basis of the use of AICAR, a pharmacologic...
متن کاملRegulation 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...
متن کاملAMP-activated protein kinase: structure and regulation.
Mammalian AMP-activated protein kinase (AMPK) is a serine/threonine protein kinase that acts as a sensor of cellular energy status. It is activated by a large variety of cellular stresses that increase cellular AMP and decrease ATP levels and also by physiological stimuli, such as muscle contraction, or by hormones such as leptin and adiponectin. AMPK modulates multiple metabolic pathways. As a...
متن کاملAMP-activated protein kinase and the regulation of glucose transport.
The AMP-activated protein kinase (AMPK) is an energy-sensing enzyme that is activated by acute increases in the cellular [AMP]/[ATP] ratio. In skeletal and/or cardiac muscle, AMPK activity is increased by stimuli such as exercise, hypoxia, ischemia, and osmotic stress. There are many lines of evidence that increasing AMPK activity in skeletal muscle results in increased rates of glucose transpo...
متن کاملRedox Regulation of the AMP-Activated Protein Kinase
UNLABELLED Redox state is a critical determinant of cell function, and any major imbalances can cause severe damage or death. OBJECTIVES The aim of this study is to determine if AMP-activated protein kinase (AMPK), a cellular energy sensor, is activated by oxidants generated by Berberine in endothelial cells (EC). METHODS Bovine aortic endothelial cells (BAEC) were exposed to Berberine. AMP...
