Ischemia-reperfusion (IR) injury involves complex pathological processes in which reduction of nitric oxide (NO) bioavailability is suggested as a key factor. Inorganic nitrate can form NO in vivo via NO synthase-independent pathways and may thus provide beneficial effects during IR. Herein we evaluated the effects of dietary nitrate supplementation in a renal IR model. Male mice (C57BL/6J) were fed nitrate-supplemented chow (1.0mmol/kg/day) or standard chow for two weeks prior to 30min ischemia and during the reperfusion period...

Endothelial mechanotransduction is important for vascular function but alterations and activation of vascular mechanosensory proteins have not been investigated in humans. In endothelial cell culture, simple sugars effectively impair mechanosensor proteins. To study mechanosensor- and vascular function in humans, twelve young healthy male subjects supplemented their diet with 3 × 75 g sucrose day(-1) for 14 days in a randomized cross-over design. Before and after the intervention period, the hyperemic response to passive lower leg movement and active knee extensor exercise was determined by ultrasound doppler...

Arsenic (As) contamination in rice leads to yield decline and causes carcinogenic risk to human health. Although the role of nitric oxide (NO) in reducing As toxicity is known, NO-mediated genetic modulation in the plant during arsenic toxicity has not yet been established. We analyzed the key components of NO metabolism and the correlations between NO interaction and arsenic stress using rice as a relevant model plant. Illumina sequencing was used to investigate the NO-mediated genome-wide temporal transcriptomic modulation in rice root upon AsIII exposure during 12 days (d) of the growth period...

The use of doxorubicin (DOXO) as a chemotherapeutic drug has been hampered by cardiotoxicity leading to cardiomyopathy and heart failure. Folic acid (FA) is a modulator of endothelial nitric oxide (NO) synthase (eNOS), which in turn is an important player in diseases associated with NO insufficiency or NOS dysregulation, such as pressure overload and myocardial infarction. However, the role of FA in DOXO-induced cardiomyopathy is poorly understood. The aim of this study was to test the hypothesis that FA prevents DOXO-induced cardiomyopathy by modulating eNOS and mitochondrial structure and function...

Vitamin D deficiency induced by diabetes mellitus is tightly associated with neurodegenerative diseases, but the mechanism is still unknown. Endoplasmic reticulum stress (ER stress) is involved in hippocampal lesion and promote diabetic neuropathy, so we focus on the effects of 1, 25-dihydroxy vitamin D3 on ER stress in hippocampus of diabetic rats. Streptozotocin (STZ)-induced diabetic rats were administrated with different doses of vitamin D and divided into 3 groups: high, low, and blank, compared to wild-type rats which were received the same treatment...

Although high dose n-3 PUFA supplementation reduces exercise- and hyperpnoea-induced bronchoconstriction (EIB/HIB), there are concurrent issues with cost, compliance and gastrointestinal discomfort. It is thus pertinent to establish the efficacy of lower n-3 PUFA doses. Eight male adults with asthma and HIB and eight controls without asthma were randomly supplemented with two n-3 PUFA doses (6·2 g/d (3·7 g EPA and 2·5 g DHA) and 3·1 g/d (1·8 g EPA and 1·3 g DHA)) and a placebo, each for 21 d followed by 14 d washout...

Hypertension is associated with enhanced vascular oxidative stress and impaired endothelial function, which is related to an imbalance between reactive oxygen species and nitric oxide bioavailability. Short-term supplementation with a polyphenol-rich powdered red wine pomace seasoning (RWPS) was investigated for its effects on blood pressure and biomarkers of endothelial dysfunction and oxidative status in a model of essential hypertension. Male spontaneously hypertensive rats (SHRs) and normotensive Wistar-Kyoto rats (12-week-old, 5 rats per group) were administered RWPS (300 mg kg(-1) day(-1); equivalent to 7...

Recently dietary nitrate supplementation has been shown to improve exercise capacity in healthy individuals through a potential nitrate-nitrite-nitric oxide pathway. Nitric oxide has been shown to play an important role in compensatory vasodilation during exercise under hypoperfusion. Previously we established that certain individuals lack a vasodilation response when perfusion pressure reductions compromise exercising muscle blood flow. Whether this lack of compensatory vasodilation in healthy young individuals can be restored with dietary nitrate supplementation is unknown...

Asymmetric dimethylarginine (ADMA), an inhibitor of nitric oxide synthase, is a novel risk factor of cardiovascular disease. Endothelial progenitor cells (EPCs) bear typical endothelial characteristics and are thought to contribute to neovascularization by providing new endothelial cells (ECs) after arterial injury. Many studies have shown that ADMA can induce EPC apoptosis and dysfunction, but the underlying mechanism is not well understood. EPCs from umbilical cord blood were cultured in EGM-2 medium with particular growth factors and supplemented with 10% fetal bovine serum...

This study investigated biological activities including antioxidative stress, anti-inflammation, and anti-insulin resistance of Anoectochilus burmannicus aqueous extract (ABE). The results showed abilities of ABE to scavenging DPPH and ABTS free radicals in a dose-dependent manner. Besides, ABE significantly reduced nitric oxide (NO) production in the lipopolysaccharide (LPS)-treated RAW 264.7 via inhibition of mRNA and protein expressions of nitric oxide synthase (iNOS). The LPS-induced mRNA expressions of cyclooxygenase-2 (COX-2) and interleukin 1β (IL-1β) were suppressed by ABE...

BACKGROUND: Recent research has indicated that pomegranate extract (POMx) may improve performance during aerobic exercise by enhancing the matching of vascular oxygen (O2) provision to muscular requirements. POMx is rich in ellagitannin polyphenols and nitrates (NO3(-)), which are both associated with improvements in blood flow and O2 delivery. Primarily, this study aimed to determine whether POMx improves performance in a cycling time trial to exhaustion at 100%VO2max (TTE100%) in highly-trained cyclists...

Omega-3 and omega-6 polyunsaturated fatty acids (PUFAs), such as α-linolenic and linoleic acids, are essential fatty acids in mammals, because they cannot be synthesized de novo. However, fat-1 transgenic mice can synthesize omega-3 PUFAs from omega-6 PUFAs without dietary supplementation of omega-3, leading to abundant omega-3 PUFA accumulation in various tissues. In this study, we used fat-1 transgenic mice to investigate the role of omega-3 PUFAs in response to inflammatory pain. A high omega-3 PUFA tissue content attenuated formalin-induced pain sensitivity, microglial activation, inducible nitric oxide synthase expression, and the phosphorylation of NR2B, a subunit of the N-methyl-d-aspartate (NMDA) receptor...

Nitric oxide (NO) is extensively involved in various growth processes and stress responses in plants; however, the regulatory mechanism of NO-modulated cellular sugar metabolism is still largely unknown. Here, we report that NO significantly inhibited monosaccharide catabolism by modulating sugar metabolic enzymes through S-nitrosylation (mainly by oxidizing dihydrolipoamide, a cofactor of pyruvate dehydrogenase). These S-nitrosylation modifications led to a decrease in cellular glycolysis enzymes and ATP synthase activities as well as declines in the content of acetyl coenzyme A, ATP, ADP-glucose, and UDP-glucose, which eventually caused polysaccharide-biosynthesis inhibition and monosaccharide accumulation...

Cardioprotective strategies to prevent damage to mitochondria in acute myocardial infarction are warranted to reduce lethal myocardial ischemia/reperfusion (I/R) injury. Mitochondrial antagonists in I/R are reactive oxygen species (ROS), deteriorated calcium signaling, permeabilization of the mitochondrial outer membrane (MOM) and deranged mitochondrial structural dynamism (fusion and fission). Nitric oxide (NO) related signaling can protect hearts from I/R. Albeit the underlying signaling is incompletely resolved, recent data point to a particular involvement of protective posttranslational modification of mitochondrial elements...
