Abstract
Levels of phospholipid-related metabolites of chronic lymphocytic leukemia lymphocytes (CLL) and normal human lymphocytes were quantified using phosphorus magnetic resonance spectroscopy. The CLL cells versus normal lymphocytes showed significant increases of phosphoethanolamine(Etn-P) (8.11+/-2.10 mean+/-S.E., micromol/g wet weight, n=12 versus 3.63+/-1.10, n=3, P<or=0.002), phosphocholine (2.10+/-0.37, n=12 versus 0.36+/-0.09, n=3, P<or=0.01), glycerophosphoethanolamine (0.26+/-0.03, n=10 versus 0.11+/-0.05, n=3, P<or=0.004), and glycerophosphocholine (0.33+/-0.03, n=10 versus 0.17+/-0.05, n=3, P<or=0.003). Further, the phospholipid precursor ethanolamine (Eth) was studied in blood and was found significantly lowered in CLL patients (4.6+/-1.6 microM, n=25) compared to normal volunteers (7.7+/-2.5, n=12, P<or=0.001). Increased intermediates with depletion of precursors suggest the presence of sustained phospholipid metabolism activation in CLL.Entities:
