OBJECTIVE
Stroke is a leading cause of morbidity and mortality. This study aimed to determine whether nicotinamide administration could improve remyelination after stroke and reveal the underlying mechanism.
METHODS
Adult male C57BL/6J mice were intraperitoneally (i.p.) administered with
The purpose of the current study was to investigate aspects of improved bioenergetic function using nicotinamide during stroke. Using a global ischemia-reperfusion mouse model, ATP was depleted by 50% in the brain. The use of nicotinamide to provide a large reserve of brain NAD+ restored ATP levels
Nicotinamide adenine dinucleotide phosphate oxidase (NOX) is a multisubunit enzyme complex that utilizes nicotinamide adenine dinucleotide phosphate to produce superoxide anions and other reactive oxygen species. Under normal circumstances, reactive oxygen species mediate a number of important
OBJECTIVE
Reperfusion after stroke leads to infiltration of inflammatory cells into the ischemic brain. Nicotinamide adenine dinucleotide phosphate oxidase (NOX2) is a major enzyme system that generates superoxide in immune cells. We studied the effect of NOX2 derived from the immune cells in the
OBJECTIVE
Stroke is a leading cause of mortality and disability. Nicotinamide phosphoribosyltransferase (Nampt) is the rate-limiting enzyme in mammalian nicotinamide adenine dinucleotide (NAD)(+) biosynthesis and contributes to cell fate decisions. However, the role of Nampt in brain and stroke
OBJECTIVE
Nicotinamide adenine dinucleotide (NAD) is a ubiquitous fundamental metabolite. Nicotinamide phosphoribosyltransferase (Nampt) is the rate-limiting enzyme for mammalian NAD salvage synthesis and has been shown to protect against acute ischemic stroke. In this study, we investigated the
OBJECTIVE
Nicotinamide protects against brain damage in ischemia-reperfusion. However, the dosage and time of treatment require clarification. It is also not clear if nicotinamide can protect against both necrosis and apoptosis.
METHODS
Dose-response and time-effect studies were designed. Transient
Nicotinamide mononucleotide adenylyltransferase 1 (NMNAT1) is a nicotinamide adenine dinucleotide biosynthetic enzyme. It has been shown to be neuroprotective against neonatal excitotoxicity-induced brain injury, but its role in ischemic stroke is unclear. In this study, the role of NMNAT1 in
OBJECTIVE
Our previous study has defined a role of TP53-induced glycolysis and apoptosis regulator in neuroprotection against ischemic injury through increasing the flow of pentose phosphate pathway. We hypothesized that the pentose phosphate pathway product nicotinamide adenine dinucleotide
Although physical exercise has emerged as a potential therapeutic modality for functional deficits following ischemic stroke, the extent of this effect appears to be contingent upon the time of exercise initiation. In the present study, we assessed how exercise timing affected brain damage through
Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) was originally identified in immune cells as playing an important microbicidal role. In stroke and cerebrovascular disease, inflammation is increasingly being recognized as contributing negatively to neurological outcome, with NOX as
Since hypertension and/or hyperglycemia are risk factors for stroke, we examined whether the putative neuroprotectant, nicotinamide (NAm), could protect spontaneously hypertensive rats (SHR) or diabetic Fischer 344 rats against focal cerebral ischemia using a model of permanent middle cerebral
Delayed treatment with nicotinamide (NAm) protects male rats against cerebral ischemia. Since the preponderant use of male animals in stroke research may produce results not applicable to female stroke patients due to gender-related differences, we examined whether delayed NAm treatment could
