Homocysteine, a sulfur amino acid, is an intermediate metabolite of methionine. In 1969, McCully reported autopsy evidence of extensive arterial thrombosis and atherosclerosis in children with elevated plasma homocysteine concentrations and homocystinuria.

Folate catabolites in spot urine as non-invasive biomarkers of folate status during habitual intake and folic acid supplementation. [PDF]
Folate status, as reflected by red blood cell (RCF) and plasma folates (PF), is related to health and disease risk. Folate degradation products para-aminobenzoylglutamate (pABG) and para-acetamidobenzoylglutamate (apABG) in 24 hour urine have recently ...

Elevated levels of homocysteine (Hcy), a non-proteinogenic amino acid, may lead to a host of manifestations across the biological systems, particularly the nervous system. Defects in Hcy metabolism have been associated with many neurodegenerative diseases including glaucoma, i.e., the leading cause of blindness. However, the pathophysiology of elevated

Treatment of Alzheimer's Disease with Anti-Homocysteic acid Antibody [PDF]
Homocysteic acid (HA) may play an important role in Alzhiemer disease (AD) as we previously reported that HA induced accumulation of intraneuronal A[beta]42. In this study, we first analyzed HA levels in a mouse model of AD.

Homocysteine and familial longevity: the Leiden Longevity Study.
Homocysteine concentrations are a read-out of methionine metabolism and have been related to changes in lifespan in animal models. In humans, high homocysteine concentrations are an important predictor of age related disease.

NF-kappaB activation is associated with homocysteine-induced injury in Neuro2a cells
Background Perinatal exposure to hyperhomocysteinemia might disturb neurogenesis during brain development and growth. Also, high levels of homocysteine trigger neurodegeneration in several experimental models.

Importance of Raised Serum Homocysteine Levels in Ischemic Stroke Patients [PDF]
Background: Around 5.5 million people die from stroke each year, making it the second leading cause of mortality worldwide. Increased homocysteine levels lead to early neurological deteriorations in ischemic stroke and may have an association with other

Plasma homocysteine, folate and vitamin B(12) compared between rural Gambian and UK adults. [PDF]
The disease risk indicator plasma total homocysteine (tHcy) is influenced by genetic and environmental factors, including folate and vitamin B(12) status. Little is known about the determinants of tHcy in rural West Africa.

Evidence Favoring a Positive Feedback Loop for Physiologic Auto Upregulation of hnRNP-E1 during Prolonged Folate Deficiency in Human Placental Cells [PDF]
Background: Previously, we determined that heterogeneous nuclear ribonucleoprotein E1 (hnRNP-E1) functions as an intracellular physiologic sensor of folate deficiency.

Transcobalamin C776G genotype modifies the association between vitamin B12 and homocysteine in older Hispanics. [PDF]
Background/objectivesA common polymorphism, C776G, in the plasma B12 transport protein transcobalamin (TC), encodes for either proline or arginine at codon 259.
