Platelet Incorporation of Labelled Adenosine and Adenosine Diphosphate

Thrombosis and Haemostasis, 1969
SummaryAfter incubation of platelet-rich plasma with labelled adenosine or ADP, platelet incorporation of radioactivity was assessed. Platelets were rapidly separated for counting by filtration through cellulose acetate Millipore. Inulin-H3 served as a plasma marker, and triple isotope techniques permitted simultaneous assessment of the behavior of the

THE SYNTHESIS AND PROPERTIES OF ADENOSINE-2′ DIPHOSPHATE AND ADENOSINE-3′ DIPHOSPHATE

Canadian Journal of Biochemistry, 1967
Adenosine-2′ diphosphate (A2'DP) and adenosine-3′ diphosphate (A3′DP) have been prepared by reaction between the corresponding mononucleotides with phosphoramidic acid in formamide. The products were isolated by ion-exchange chromatography on DEAE-cellulose and characterized by enzymic and chemical methods. A major side reaction in the synthesis is the

Nonenzymic ADP-ribosylation of poly(adenosine diphosphate ribose)

Biochemistry, 1985
Poly(adenosine 5'-diphosphate ribose) [poly(ADP-ribose]) is spontaneously ADP-ribosylated when it is incubated with nicotinamide adenine dinucleotide, especially in 0.5 M NaCl and at an alkaline pH. The ADP-ribose residues are monomeric and are attached to the middle of polymer chains.

Magnesium, Adenosine Diphosphate and Blood Platelets [PDF]

Nature, 1966
RECENTLY we reported1 a relative plasma magnesium deficiency in a group of forty male patients with acute myocardial infarction (mean of 2.3 mg per 100 ml.) compared with thirty-six normal healthy males (mean of 2.6 mg per 100 ml.) in the same age group. In addition it was shown that magnesium added to fresh whole blood delays the clumping of platelets

Charge-balanced metal fluoride complexes for protein kinase A with adenosine diphosphate and substrate peptide SP20.

Angewandte Chemie, 2012
Well-balanced: 19F NMR spectroscopy defined a trifluoromagnesate complex for protein kinase A (multicolored) with adenosine diphosphate (black), the MgF3− ion (green), and the SP20 peptide substrate (purple with dots).

Poly(adenosine diphosphate ribose)

1982
Publisher Summary This chapter discusses the higher-order structure of poly(adenosine diphosphate ribose) [poly(ADPR)], poly(ADPR) polymerase purification and its properties, and molecular mechanisms of histone- and elongation-factor (EF-2)-ADP-ribosylation.

Adenosine Diphosphate-Degrading Activity in Placenta

Clinical Science, 1983
1. The degradation of ADP by the placenta and umbilical artery was investigated. 2. Supernatants from incubations of finely chopped placental and umbilical arterial tissue were incubated with [14C]ADP for various durations from 0 to 30 min. 3.

Cytoplasmic poly(adenosine diphosphate-ribose) polymerase expression is predictive and prognostic in patients with breast cancer treated with neoadjuvant chemotherapy.

Journal of Clinical Oncology, 2011
PURPOSE Poly(adenosine diphosphate-ribose) polymerase (PARP) plays a key role in DNA repair and cellular stress response. Inhibitors of PARP show promising clinical activity in metastatic, triple-negative or BRCA-mutated breast cancer.

Net adenosine diphosphate accumulation in mitochondria

Archives of Biochemistry and Biophysics, 1977
Abstract In addition to the adenine nucleotide exchange translocator, corn mitochondria possess a transport mechanism for the net accumulation of [3H]ADP. The accumulation is energy linked and requires the presence of phosphate and Mg2+. Inhibition of the adenine nucleotide exchange translocator with carboxyatractyloside does not block ADP ...
