Choline deficiency in mice and humans is associated with increased plasma homocysteine concentration after a methionine load.
BACKGROUND Elevated concentrations of homocysteine in blood may be an independent risk factor for the development of atherosclerosis. Elevated homocysteine concentrations can be caused by decreased methylation of homocysteine to form methionine, as occurs in folate deficiency. A parallel pathway exists for methylation of homocysteine, in which choline, by way of betaine, is the methyl donor. ...
متن کاملPlasma choline concentration in humans fed parenterally1
Choline is an essential nutrient for some mammals; it is used for membrane and neurotransmitter synthesis. We analyzed plasma samples, obtained periodically during TPN therapy, for choline concentration. Malnourished patients referred to a nutrition support service were prospectively assigned to be treated with daily infusions of amino acids with, and without, supplemental daily infusions of li...
متن کاملIn vitamin B12 deficiency, higher serum folate is associated with increased homocysteine and methylmalonic acid concentrations.
To the Editor: In the December 11, 2007, issue of PNAS, Selhub et al. (1) suggest that the association between elevated serum folate and methylmalonic acid (MMA) concentrations in vitamin B12 deficiency resulted from disruption of MMA metabolism by folate. An alternative explanation is that the increase in both serum folate and MMA concentrations resulted from the severity of the vitamin B12 de...
متن کاملPlasma Homocysteine Is Associated with Increased Oxidative Stress and Antioxidant Enzyme Activity in Welders
The purpose of this study was to examine the association of vitamin B6 status and plasma homocysteine with oxidative stress and antioxidant capacities in welders. Workers were divided into either the welding exposure group (n = 57) or the nonexposure controls (n = 42) based on whether they were employed as welders. There were no significant differences in vitamin B₆ status and plasma homocystei...
متن کاملElevated Plasma Homocysteine Concentration in Opium-Addicted Individuals
Background: Although the triggering role of both opium use and elevated plasma homocysteine level for progressing atherosclerosis and, therefore, appearing coronary heart disease has been clearly determined, no study are available with respect to the relation between these to risk profiles. In the present study and for the first time, we hypothesized that the opium addiction can be potentially ...
