Reduced adenosine receptor stimulation as a pathogenic factor in hyperhomocysteinemia

In this review we discuss the hypothesis, and current evidence, that a decreased concentration of the endogenous purine-nucleoside adenosine contributes to the increased cardiovascular risk of patients with hyperhomocysteinemia...

Keywords: Adenosine, cardiovascular disease, dipyridamole, hyperhomocysteinemia

Effects of homocysteine on vascular and tissue adenosine: a stake in homocysteine pathogenicity?

Homocysteine may have deleterious effects on the cardiovascular system. It has been hypothesized that these effects may be brought about by a decrease in the adenosine concentration via the S-adenosylhomocysteine hydrolase reaction...

Keywords: S-adenosylhomocysteine hydrolase, blood flow, homocysteine pathogenicity, hyperhomocysteinemia

Hyperhomocysteinemia and macromolecule modifications in uremic patients

Hyperhomocysteinemia is present in the majority of well-nourished chronic renal failure and uremic patients...

Keywords: DNA methylation, hyperhomocysteinemia, isopeptide bonds, uremia

Molecular targeting by homocysteine: a mechanism for vascular pathogenesis

Hyperhomocysteinemia is an independent risk factor for cardiovascular disease. Although there is a growing body of evidence that homocysteine plays a causal role in atherogenesis, specific mechanisms to explain the underlying pathology have remained elusive...

Keywords: Albumin, atherogenesis, disulfide bond, glutathione peroxidase, homocysteine, hyperhomocysteinemia, molecular targeting, pKa, sulfhydryl group, vascular pathogenesis

Asymmetric dimethylarginine, homocysteine and renal function – is there a relation?

The adverse effect of hyperhomocysteinemia on the vascular wall can be partially explained by increasing plasma concentration of asymmetric dimethylarginine (ADMA), a potent inhibitor of nitric oxide synthase...

Keywords: asymmetric dimethylarginine, Hemodialysis, homocysteine, hyperhomocysteinemia

Increased homocysteine in heart failure: a result of renal impairment?

Background: Hyperhomocysteinemia may constitute a risk factor for patients with severe heart failure...

Keywords: Heart failure, hyperhomocysteinemia, renal function

Plasma homocysteine cutoff values for venous thrombosis

Background: Hyperhomocysteinemia is considered an independent risk factor for vascular occlusive diseases...

Keywords: cutoff values, hyperhomocysteinemia, Venous thrombosis

Hyperhomocysteinemia and high-density lipoprotein metabolism in cardiovascular disease

Hyperhomocysteinemia (HHcy) is a significant and independent risk factor for cardiovascular disease (CVD) and the underlying mechanism is unclear...

Keywords: atherosclerotic cardiovascular disease, high-density lipoprotein metabolism, hyperhomocysteinemia
