Quantification of phosphocholine and glycerophosphocholine with 31P edited 1H NMR spectroscopy.
Choline and the related compounds phosphocholine (PC) and glycerophosphocholine (GPC) are considered to be important metabolites in oncology. Past studies have demonstrated correlations linking the relative ratios and concentrations of these metabolites with the development and progression of cancer. Currently, in vivo and tissue ex vivo magnetic resonance spectroscopy methods have mostly cente...
متن کاملPhospholipid metabolism in cancer cells monitored by 31P NMR spectroscopy.
Addition of choline, ethanolamine, or hemicholinium-3 (a choline kinase inhibitor) to the perfusate of human breast cancer cells monitored by 31P NMR spectroscopy resulted in significant changes to phosphomonoester (PME) and phosphodiester (PDE) signals. These results enable us to assign the PMEs to phosphcholine (PC) and phosphoethanolamine (PE), the PDEs to glycerophosphorylcholine and glycer...
متن کامل31P NMR spectroscopy of rat organs, in situ, using chronically implanted radiofrequency coils.
A technique for making 31P NMR spectroscopic measurements in rat kidney, heart, and liver in vivo is presented. Two-turn solenoid coils were surgically implanted around the organ sufficiently in advance of NMR experiments to allow recovery of the animal. These chronically implanted coils allowed acquisition of high-resolution spectra at 40.5 and 97.3 MHz. No resolution improvement occurred at t...
متن کاملAssessment of Cardiac Function and Energetics in Isolated Mouse Hearts Using 31P NMR Spectroscopy
Bioengineered mouse models have become powerful research tools in determining causal relationships between molecular alterations and models of cardiovascular disease. Although molecular biology is necessary in identifying key changes in the signaling pathway, it is not a surrogate for functional significance. While physiology can provide answers to the question of function, combining physiology...
متن کاملCritical temperatures in the cephalopod Sepia officinalis investigated using in vivo 31P NMR spectroscopy.
The present study was designed to test the hypothesis of an oxygen limitation defining thermal tolerance in the European cuttlefish (Sepia officinalis). Mantle muscle organ metabolic status and pHi were monitored using in vivo 31P NMR spectroscopy, while mantle muscle performance was determined by recording mantle cavity pressure oscillations during ventilation and spontaneous exercise. Under c...
