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,

36 degree step size of proton-driven c-ring rotation in FoF1-ATP synthase [PDF]

, 2009
Synthesis of the biological "energy currency molecule" adenosine triphosphate ATP is accomplished by FoF1-ATP synthase. In the plasma membrane of Escherichia coli, proton-driven rotation of a ring of 10 c subunits in the Fo motor powers catalysis in the ...

Progress of Immune‐Inducible Biomaterials for Post‐Ablation Cancers

Advanced Healthcare Materials, EarlyView.
The presence of residual tumors after ablative therapies poses a significant challenge, generally resulting in recurrence and metastases. This review offers a concise overview of immune‐inducible biomaterials from the perspective of the cancer‐immunity cycle, and how they enhance antitumor immunity through diverse mechanisms following ablative ...

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.

Digitonin‐Loaded Nanoscale Metal–Organic Framework for Mitochondria‐Targeted Radiotherapy‐Radiodynamic Therapy and Disulfidptosis

Advanced Materials, EarlyView.
A mitochondria‐targeted cationic nanoscale metal organic framework shows strong radiotherapy‐radiodynamic therapy effects and selectively releases digitonin in acidic tumor microenvironments to induce disulfidptosis of cancer cells and downregulate immune checkpoints in cancer and T cells, thereby eliciting strong antitumor immunity to effectively ...

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 ...

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 ...

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,
