Data demonstrating the direct phosphorylation of tyrosine hydroxylase [tyrosine 3-monooxygenase; L-tyrosine, tetrahydropteridine:oxygen oxidoreductase (3-hydroxylating), EC 1.14.16.2] purified from rat pheochromocytoma by ATP, Mg2+ and cyclic AMP-dependent protein kinase catalytic subunit are presented. The incorporation of phosphate is highly correlated with the activation of the hydroxylase w...
Background—Acute coronary syndrome is a leading cause of death in developed countries. Follistatin-like 1 (FSTL1) is a myocyte-derived secreted protein that is upregulated in the heart in response to ischemic insult. Here, we investigated the therapeutic impact of FSTL1 on acute cardiac injury in small and large preclinical animal models of ischemia/reperfusion and dissected its molecular mecha...
The AMPK (AMP-activated protein kinase)-related protein kinase subfamily of the human kinome comprises 12 members closely related to the catalytic alpha1/alpha2 subunits of AMPK. The precise role of the AMPK-related kinases and their in vivo substrates is rather unclear at present, but some are involved in regulating cell polarity, whereas others appear to control cellular differentiation. Of t...
In the rat liver epithelial cell line Clone 9, the V(max) for glucose uptake is acutely increased by inhibition of oxidative phosphorylation and by osmotic stress. By using a membrane-impermeant photoaffinity labelling reagent together with an isoform-specific antibody, we have, for the first time, provided direct evidence for the involvement of the GLUT1 glucose transporter isoform in this res...
AMPK (AMP-activated protein kinase) is activated allosterically by AMP and by phosphorylation of Thr172 within the catalytic alpha subunit. Here we show that mutations in the regulatory gamma subunit reduce allosteric activation of the kinase by AMP. In addition to its allosteric effect, AMP significantly reduces the dephosphorylation of Thr172 by PP (protein phosphatase)2Calpha. Moreover, a mu...
OBJECTIVE As adenosine monophosphate (AMP)-activated protein kinase both controls cytoskeleton organization in endothelial cells and exerts anti-inflammatory effects, we here postulated that it could influence vascular permeability and inflammation, thereby counteracting cardiac wall edema during sepsis. DESIGN Controlled animal study. SETTINGS University research laboratory. SUBJECTS C57...
