چکیده

Failure to maintain a normal in vivo erythrocyte half-life results in the development of hemolytic anemia. Half-life is affected by numerous factors, including energy balance, electrolyte gradients, reactive oxygen species, and membrane plasticity. The heterotrimeric AMP-activated protein kinase (AMPK) is an evolutionarily conserved serine/threonine kinase that acts as a critical regulator of cellular energy balance. Previous roles for the alpha 1 and gamma 1 subunits in the control of erythrocyte survival have been reported. In the work described here, we studied the role of the beta 1 subunit in erythrocytes and observed microcytic anemia with compensatory extramedullary hematopoiesis together with splenomegaly and increased osmotic resistance.

Beta-adrenergic regulation of the muscarinic-gated K+ channel via cyclic AMP-dependent protein kinase in atrial cells.

Cholinergic and beta-adrenergic stimulations of ionic currents are major physiological mechanisms in the regulation of heart rate and contractility. Muscarinic receptor stimulation is known to reduce beta-adrenergic effects on calcium current via reduction of cyclic AMP. Whether the beta-adrenergic stimulation affects the muscarinic response is not known. I report here that the beta-adrenergic ...

Post-translational modifications of the beta-1 subunit of AMP-activated protein kinase affect enzyme activity and cellular localization.

The AMP-activated protein kinase (AMPK) is a ubiquitous mammalian protein kinase important in the adaptation of cells to metabolic stress. The enzyme is a heterotrimer, consisting of a catalytic alpha subunit and regulatory beta and gamma subunits, each of which is a member of a larger isoform family. The enzyme is allosterically regulated by AMP and by phosphorylation of the alpha subunit. The...

AMP-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...

Effects of thyroid state on AMP-activated protein kinase and acetyl-CoA carboxylase expression in muscle.

AMP-activated protein kinase (AMPK) consists of three subunits: alpha, beta, and gamma. Two isoforms exist for the alpha-subunit (alpha(1) and alpha(2)), two for the beta-subunit (beta(1) and beta(2)), and three for the gamma-subunit (gamma(1), gamma(2), and gamma(3)). Although the specific roles of the beta- and gamma-subunits are not well understood, the alpha-subunit isoforms contain the cat...

Homogenous Fluorescent Assays for Characterizing Small-Molecule Activators of AMP-Activated Protein Kinase (AMPK)

AMP activated protein kinase (AMPK) is a key regulator of cellular metabolism. AMPK activity is modulated in part by binding of AMP to the gamma-subunit of the kinase, which increases the activity of the catalytic alpha-subunit. Because increased AMPK activity in the liver and in skeletal muscle leads to increased fatty acid oxidation and decreased cholesterol and fatty acid biosynthesis, activ...
