Determination of polyamine metabolome in plasma and urine by ultrahigh performance liquid chromatography–tandem mass spectrometry method: Application to identify potential markers for human hepatic cancer

To evaluate the potential relationship between cancer and polyamine metabolome, a UHPLC-MS/MS method has been developed and validated for simultaneous determination of polyamine precursors, polyamines, polyamine catabolite in human plasma and urine. Polyamine precursors including L-ornithine, lysine, L-arginine and S-adenosyl-L-methionine; polyamines including 1,3-diaminopropane, putrescine, cadaverine, spermidine, spermine, agmatine,...
