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.

Phosphorylation of adenosine monophosphate in the mitochondrial matrix [PDF]

Biochemical Journal, 1978
The origin of the GTP needed for th phosphorylation of AMP in the mitochondrial matrix was investigated. When short-chain fatty acids are metabolized by hepatocytes, AMP is readily formed within the matrix by the butyryl-CoA ligase (AMP-forming) reaction (EC 6.2.1.2).

Differences in growth and alkaline phosphatase activity between Microcystis aeruginosa and Chlorella pyrenoidosa in response to media with different organic phosphorus

Journal of Limnology, 2011
The growth of Microcystis aeruginosa and Chlorella pyrenoidosa in three dissolved organic phosphorus sources (glucose-1- phosphate, adenosine triphosphate, cyclic-adenosine monophosphate) were studied in cultures separated by a dialysis membrane. Results

Development of Single-Molecule Electrical Identification Method for Cyclic Adenosine Monophosphate Signaling Pathway

Nanomaterials, 2021
Cyclic adenosine monophosphate (cAMP) is an important research target because it activates protein kinases, and its signaling pathway regulates the passage of ions and molecules inside a cell.

Crosstalk between G-protein and Ca2+ pathways switches intracellular cAMP levels [PDF]

, 2001
Cyclic adenosine monophosphate and cyclic guanosine monophosphate are universal intracellular messengers whose concentrations are regulated by molecular networks comprised of different isoforms of the synthases adenylate cyclase or guanylate cyclase and ...

Ischemic preconditioning attenuates portal venous plasma concentrations of purines following warm liver ischemia in man [PDF]

, 2005
Background/Aims: Degradation of adenine nucleotides to adenosine has been suggested to play a critical role in ischemic preconditioning (IPC). Thus, we questioned in patients undergoing partial hepatectomy whether (i) IPC will increase plasma purine ...
