Hyperhomocysteinemia is associated with an increased risk of Alzheimer's disease (AD). Our previous work has demonstrated that combined folate and vitamin B12 (vit-B12) supplementation prevents tau hyperphosphorylation and memory deficits induced by acute administration of homocysteine in young
The aim of the present work was to investigate the actions of a chemically induced chronic hyperhomocysteinemia model on intermediate filaments (IFs) of cortical and hippocampal neural cells and explore signaling mechanisms underlying such effects. Results showed that in hyperhomocysteinemic rats
The study has been designed to investigate the effect of Bis-(maltolato) oxovanadium (BMOV), an inhibitor of protein tyrosin phosphatase (PTPase), in diabetes mellitus and hyperhomocysteinemia induced vascular endothelial dysfunction. Streptozotocin (55 mg kg(-1), i.v.) and methionine (1.7% w/w,
BACKGROUND
Hepatitis C virus (HCV) infection is one of the leading causes of chronic liver disease (CLD). About 80% of those exposed to the virus develop a chronic infection. Hyperhomocysteinemia, which is an independent risk factor for atherosclerotic vascular disease and thromboembolism, may
Liver transplant recipients have an increased risk for cardiovascular disease because of a high incidence of obesity, arterial hypertension, diabetes mellitus, and hyperlipidemia. Hyperhomocysteinemia has been found to be an important risk factor for cardiovascular disease in large studies. Fasting
OBJECTIVE
To explore the effect of hyperhomocysteinemia on vascular calcification and the underlying mechanism of it.
METHODS
Arterial calcification of Sprague-Dawley rats was induced by vitamin D3 plus nicotine. Hyperhomocysteinemia was established by feeding high methionine diet for six weeks and
Osteoporosis is an age-related bone disease, affecting mainly postmenopausal women, characterized by decreased bone mineral density (BMD) and consequent risk of fractures. Homocysteine (Hcy), a sulfur-aminoacid whose serum level is regulated by methylenetrahydrofolate reductase (MTHFR) activity and
Alzheimer's disease (AD) neuropathology is characterized by the accumulation of phosphorylated tau and amyloid-beta peptides derived from the amyloid precursor protein (APP). Elevated blood levels of homocysteine are a significant risk factor for many age-related diseases, including AD. Impaired
UNASSIGNED
Hyperhomocysteinemia (HHcy) is an independent risk factor for dementia, including Alzheimer's disease (AD). Lowering homocysteine levels with folic acid treatment with or without vitamin B12 was shown few clinical benefits on cognition.
UNASSIGNED
To verify the effect of emodin, a
OBJECTIVE
Vascular inflammation, including the expression of inflammatory cytokines in endothelial cells, plays a critical role in hyperhomocysteinaemia-associated vascular diseases. Cathepsin V, specifically expressed in humans, is involved in vascular diseases through its elastolytic and
Ginkgo biloba extract EGb761 has shown the neuroprotective effects on Alzheimer's disease (AD) through the protection against the Aβ-induced neurotoxicity. However, it is not completedly clear whether EGb761 attenuates tau hyperphosphorylation, another of the most prominent mechanisms underlying the
Hyperhomocysteinemia is an independent risk factor of Alzheimer's disease (AD), which is not diagnosed for many years before onset due to lack of peripherally detectable early biomarkers. Visual dysfunction is prevalent in AD patients and correlates with the severity of cognitive defects.
Hyperhomocysteinemia increases the risk of Alzheimer's disease (AD), but the mechanism is elusive. Here, we found that high plasma homocysteine induced by vena caudalis injection for 2 weeks could induce AD-like tau hyperphosphorylation at multiple sites in rat brain hippocampus. Homocysteine
Alzheimer's disease (AD) has multiple etiopathogenic factors, yet the definitive cause remains unclear and the therapeutic strategies have been elusive. Combination therapy, as one of the promising treatments, has been studied for years and may exert synergistic beneficial effects on AD through
Alzheimer's disease (AD) is a multifactorial neurodegenerative disease for which there are limited therapeutic strategies. Protein phosphatase 2A (PP2A) activity is decreased in AD brains, which promotes the hyperphosphorylation of Tau and APP, thus participate in the formation of neurofibrillary
