<em>Bacillus anthracis</em> Edema Factor Substrate Specificity: Evidence for New Modes of Action [PDF]

Toxins, 2012
Since the isolation of <em>Bacillus anthracis</em> exotoxins in the 1960s, the detrimental activity of edema factor (EF) was considered as adenylyl cyclase activity only.

Adenosine Triphosphate Inhibition in Myosin Adenosine Triphosphate Systems

Journal of Biological Chemistry, 1971
Abstract Factors affecting inhibition of myosin ATPase by ATP, such as concentration of the enzyme, of ATP, and of the divalent metals, calcium and magnesium, have been studied and the results are reported here. Experiments were carried out under conditions in which no known magnesium effects occurred, so that only the effect of calcium on the ...

Age-associated metabolic and morphologic changes in mitochondria of individual mouse and hamster oocytes. [PDF]

PLoS ONE, 2013
BACKGROUND: In human oocytes, as in other mammalian ova, there is a significant variation in the pregnancy potential, with approximately 20% of oocyte-sperm meetings resulting in pregnancies.

Purinergic Signaling in the Regulation of Gout Flare and Resolution

Frontiers in Immunology, 2021
Gout flares require monosodium urate (MSU) to activate the NLRP3 inflammasome and secrete sufficient IL-1β. However, MSU alone is not sufficient to cause a flare. This is supported by the evidence that most patients with hyperuricemia do not develop gout

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC [PDF]

, 2012
Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways.

Computerized Modeling of Adenosine Triphosphate, Adenosine Triarsenate and Adenosine Trivanadate

Molecules, 2012
Computerized molecular models of adenosine triphosphate, adenosine tri-arsenate and adenosine trivanadate have been generated using the molecular mechanics technique. The analysis of structural parameters indicated that, at least theoretically, adenosine

ABC gene expression profiles have clinical importance and possibly form a new hallmark of cancer

Tumor Biology, 2017
Adenosine triphosphate–binding cassette proteins constitute a large family of active transporters through extracellular and intracellular membranes. Increased drug efflux based on adenosine triphosphate–binding cassette protein activity is related to the

Imaging Adenosine Triphosphate (ATP) [PDF]

The Biological Bulletin, 2016
Adenosine triphosphate (ATP) is a universal mediator of metabolism and signaling across unicellular and multicellular species. There is a fundamental interdependence between the dynamics of ATP and the physiology that occurs inside and outside the cell.
