Heme oxygenase-2 (HO-2) has been suggested to be a cytoprotective enzyme in a variety of in vivo experimental models. HO-2, the constitutive isozyme, is enriched in neurons and, under normal conditions, accounts for nearly all of brain HO activity. HO-2 deletion (HO-2-/-) leads to increased
BACKGROUND
The microsatellite polymorphism of heme oxygenase (HO)-1 gene promoter has been shown to be associated with the susceptibility to ischemic event, including coronary artery disease (CAD), myocardial infarction, and peripheral vascular disease. We aimed to examine whether the length of
To reduce side effects due to non-specific expression, the heme oxygenase-1 (HO-1) gene under control of a hypoxia-inducible erythropoietin (Epo) enhancer (pEpo-SV-HO-1) was developed for site-specific gene therapy of ischemic stroke.
pEpo-SV-HO-1 was constructed by insertion of the Epo enhancer
The hemorrhagic strokes, intracerebral (ICH) and subarachnoid hemorrhage (SAH), often have poor outcomes. Indeed, the most common hemorrhagic stroke, ICH, has the highest mortality and morbidity rates of any stroke subtype. In this report, we discuss the evidence for the staging of red blood cell
As an inducible isoform of heme oxygenase (HO), HO-1 was suggested to have an anti-oxidative stress, anti-inflammatory, anti-apoptotic and anti-proliferative effect. It was regarded as an important cytoprotective enzyme. We undertook this study to investigate whether HO-1 gene rs2071746 polymorphism
An efficient gene carrier to the brain is required for successful gene therapy of ischemic stroke. In this study, deoxycholic acid-conjugated polyethylenimine (DA-PEI) was synthesized and evaluated as a heme oxygenase-1 (HO-1) gene carrier for ischemic stroke gene therapy. Gel retardation assay and
1-Aminocyclopropanecarboxylic acid (ACPC) has been shown to protect neurons against glutamate-induced neurotoxicity by reducing N-methyl-D-aspartate (NMDA) receptor activation. Recent studies have demonstrated that several antagonists of NMDA receptors have important cardiovascular effects. In this
Stroke is the fourth leading cause of death and a major cause of disability in stroke survivors. Studies have underlined the importance of repair mechanisms in the recovery phase of stroke. Neurogenesis in response to brain injury is one of the regeneration processes that, if enhanced, may offer
(1) Background: A detailed understanding of the pathophysiology of hemorrhagic stroke is still missing. We hypothesized that expression of heme oxygenase-1 (HO-1) in microglia functions as a protective signaling pathway. (2) Methods: Hippocampal HT22 neuronal cells were exposed to heme-containing
Stroke pathogenesis involves complex oxidative stress-related pathways. The nuclear factor erythroid-2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) pathways have been considered molecular targets in pharmacologic intervention for ischemic diseases. Andrographolide, a labdane diterpene, has
Epidemiological and experimental reports have linked mild-to-moderate wine and/or grape consumption to a lowered incidence of cardiovascular, cerebrovascular, and peripheral vascular risk. This study revealed that resveratrol, an enriched bioactive polyphenol in red wine, selectively induces heme
Ginkgo biloba extract, EGb 761, a popular and standardized natural extract, contains 24% ginkgo-flavonol glycosides and 6% terpene lactones. EGb 761 is used worldwide to treat many ailments, and although a number of studies have shown its neuroprotective properties, the mechanisms of action have not
Rosmarinic acid (RA) can elicit a neuroprotective effect against ischemic stroke, but the precise molecular mechanism remains poorly understood. In this study, an experimental ischemic stroke model was established in CD-1 mice (Beijing Vital River Laboratory Animal Technology, Beijing, China) by
Stroke is the second-leading cause of death and a leading cause of serious long-term disability worldwide, with an increasing global burden due to the growing and aging population. However, strict eligibility criteria for current treatment opportunities make novel therapeutic approaches desirable.
Bilirubin (Bil) is the end product of heme catabolism. The production of Bil reflects heme oxygenase-1 expression in response to oxidative stress in various diseases. To assess the role of Bil as a marker of oxidative stress in cases of brain damage, we measured serum Bil concentrations in patients
