The Role and Molecular Mechanism of P2Y12 Receptors in the Pathogenesis of Atherosclerotic Cardiovascular Diseases

open access: yesApplied Sciences, 2021
The P2Y receptor family is a class of G protein-coupled receptors activated primarily by adenosine triphosphate (ATP), adenosine diphosphate (ADP), uridine triphosphate (UTP) and uridine diphosphate (UDP).

Adenosine diphosphate glucose and starch synthesis [PDF]

open access: yesBiochemical and Biophysical Research Communications, 1961
Received Septenber 19, 1961 In previous papers (Fekete et al., 1960; Leloir et al., 1961) an enzyme was described which catalyzes glucose transfer from uridine diphoaphate glucose (UD?G) to starch or oligosaccharides. Several synthetic nucleoside diphosphate sugars have now been tested with the same enzyme preparation.

Extracellular ATP released by osteoblasts is a key local inhibitor of bone mineralisation [PDF]

open access: yes, 2013
Previous studies have shown that exogenous ATP (>1µM) prevents bone formation in vitro by blocking mineralisation of the collagenous matrix. This effect is thought to be mediated via both P2 receptor-dependent pathways and a receptor-independent ...

Constitutively released adenosine diphosphate regulates proplatelet formation by human megakaryocytes

open access: yesHaematologica, 2012
Background The interaction of adenosine diphosphate with its P2Y1 and P2Y12 receptors on platelets is important for platelet function. However, nothing is known about adenosine diphosphate and its function in human megakaryocytes.Design and Methods We ...

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

open access: yes, 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.

Determination of Adenylate Nucleotides in Amphipod Gammarus fossarum by Ion-Pair Reverse Phase Liquid Chromatography: Possibilities of Positive Pressure Micro-Solid Phase Extraction

open access: yesSeparations, 2021
Adenine nucleotides—adenosine monophosphate, diphosphate, and triphosphate—are of utmost importance to all living organisms, where they play a critical role in the energy metabolism and are tied to allosteric regulation in various regulatory enzymes ...

Crystallization of Adenylylsulfate Reductase from Desulfovibrio gigas: A Strategy Based on Controlled Protein Oligomerization [PDF]

open access: yes, 2011
Adenylylsulfate reductase (adenosine 5′-phosphosulfate reductase, APS reductase or APSR, E.C.1.8.99.2) catalyzes the conversion of APS to sulfite in dissimilatory sulfate reduction. APSR was isolated and purified directly from massive anaerobically grown

Clinical Implications of “Tailored” Antiplatelet Therapy in Patients With Chronic Total Occlusion

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Clopidogrel nonresponsiveness is a prognostic marker after percutaneous coronary intervention. Prasugrel and ticagrelor provide a better platelet inhibition and represent the first‐line antiplatelet treatment in acute coronary syndrome.

Altered chemomechanical coupling causes impaired motility of the kinesin-4 motors KIF27 and KIF7. [PDF]

open access: yes, 2018
Kinesin-4 motors play important roles in cell division, microtubule organization, and signaling. Understanding how motors perform their functions requires an understanding of their mechanochemical and motility properties.
