Footprint traversal by ATP-dependent chromatin remodeler motor [PDF]

Physical Review E, VOL.85, 041902 (2012), 2011
ATP-dependent chromatin remodeling enzymes (CRE) are bio-molecular motors in eukaryotic cells. These are driven by a chemical fuel, namely, adenosine triphosphate (ATP). CREs actively participate in many cellular processes that require accessibility of specific segments of DNA which are packaged as chromatin. The basic unit of chromatin is a nucleosome

Microcystin-LR acute exposure does not alter in vitro and in vivo ATP, ADP and AMP hydrolysis in adult zebrafish (Danio rerio) brain membranes

Journal of Xenobiotics, 2012
Microcystins (MCs) are toxins produced by cyanobacteria during the blooms that could accumulate in aquatic animals and be relocated to higher trophic levels.

Update on Thiamine Triphosphorylated Derivatives and Metabolizing Enzymatic Complexes

Biomolecules, 2021
While the cellular functions of the coenzyme thiamine (vitamin B1) diphosphate (ThDP) are well characterized, the triphosphorylated thiamine derivatives, thiamine triphosphate (ThTP) and adenosine thiamine triphosphate (AThTP), still represent an ...

Detecting adenosine triphosphate in the pericellular space [PDF]

Interface Focus, 2013
Release of adenosine triphosphate (ATP) into the extracellular space occurs in response to a multiplicity of physiological and pathological stimuli in virtually all cells and tissues. A role for extracellular ATP has been identified in processes as different as neurotransmission, endocrine and exocrine secretion, smooth muscle contraction,

Vasodepressor Effects of Adenosine in the Cat are Independent of Cyclooxygenase, Potassium Channels, and Nitric Oxide Pathways

Drugs in R&D, 2019
Background Pulmonary arterial hypertension is a hemodynamic disorder. Signs and symptoms are generally difficult to recognize because they are non-specific. The current treatment for pulmonary arterial hypertension offers no cure or prevention; therefore,

Adenosine-Sensitive Focal Reentrant Atrial Tachycardia Originating From the Mitral Annulus-Aorta Junction

Journal of Arrhythmia, 2008
Adenosine-sensitive reentrant atrial tachycardia (AT) has been recognized to originate from the confined area of either the right or left atiroventricular nodal regions.

Fluorescent nanodiamonds for FRET-based monitoring of a single biological nanomotor FoF1-ATP synthase [PDF]

, 2009
Color centers in diamond nanocrystals are a new class of fluorescence markers that attract significant interest due to matchless brightness, photostability and biochemical inertness. Fluorescing diamond nanocrystals containing defects can be used as markers replacing conventional organic dye molecules, quantum dots or autofluorescent proteins. They can

Incorporation of Adenosine and Adenosine Triphosphate into Rat Myocardium

Japanese Heart Journal, 1969
The isolated rat heart is perfused with adenosine-8-C14, or a mixture of ATP-8-C14 and ATP-γ-P32 of known isotope (C14/P32) ratio. The results indicate that any difference between the rate of incorporation of adenosine-C14 or ATP-C14 into myocardial nucleosides and nucleotides fraction did not show significance, and also that any difference of the C14 ...

Role of P2X7 on steroid synthesis in murine luteal cells

Biotechnology & Biotechnological Equipment, 2016
The extracellular adenosine triphosphate (ATP) regulates different cellular functions through activating purinergic receptors as a signalling molecule or neurotransmitter. P2X7 is highly expressed in murine small luteal cells.
