Nicotinamide Riboside Delivery Generates NAD+ Reserves to Protect Vascular Cells Against Oxidative Damage
… do not exist. This study determines if nicotinamide riboside (NR) delivery can augment NAD+ stores and fuel resistance to oxidative stress. I established that oxidative-stress insult on vascular cells decreased NAD+ levels, accompanied by a striking increase in nuclear PAR-chain …

Longitudinal Metabolic and Proteomic Changes Studied in an Experimental Model of Traumatic Brain Injury
… suggested from these metabolic studies include, nicotinamide riboside, lipoic acid, and DHAA. They would probably be most efficacious if given soon after the initial injury. ApoE spikes at 2 weeks along with Slc1a2, in both the cortex and hippocampus coinciding with normalization of cellular …

Nampt-Mediated Nad+ Homeostasis in Skeletal Muscle: Implications for Healthy Aging
… the fundamental electron-shuttling metabolite, nicotinamide adenine dinucleotide (NAD), as a co-factor and signaling intermediate uniquely positioned to modulate whole-body energy balance through transcriptional and post-translational mechanisms. Though it has long been known that NAD supports …

Mitochondrial protein acetylation and left ventricular function in a model of hypertrophic cardiomyopathy and heart failure
… were treated with NAD+ replacement therapy with nicotinamide riboside (NR), and FXN/SIRT3 DKO mice were treated with FXN protein replacement therapy. Results: Acetylation was temporally progressive and paralleled evolution of heart failure in the FXN KO model. High levels of acetylation were …

Mutational and Structural Investigation of SARM1, a Protein that Mediates Axon Loss
… and/or WT after removing NAD precursor nicotinamide riboside (NR) or addition of Vacor, which normally leads to SARM1 activation. All artificial mutants in the SARM1 ARM domain allosteric site influence NAD levels in transfected HEK293T cells and alter basal and/or induced SARM1 NADase …

Chronic activation and downstream mechanisms of programmed axon death
… cultures. Furthermore, the NAD precursor nicotinamide riboside (NR), can decrease NAD levels in neurites expressing low levels of NMNAT2. In an attempt to test for synergy between NMNAT2 and another axon-protective protein, Stathmin-2, it becomes evident that the proteins mediate their …

Targeting Metabolic Alterations Associated With Smooth Muscle Α-Actin Pathogenic Variant Attenuates Moyamoya-Like Cerebrovascular Disease
… decreased electron transport chain activity. Nicotinamide riboside (NR), a NAD+ analogue, altered this metabolic profile. NR decreased glycolysis and increased OXPHOS by enhancing complex I activity without altering mitochondrial mass in <em>Acta2</em><sup>SMC-R179C/+</sup> SMCs. Furthermore, …

Genotype and phenotype in mitochondrial disorders
… treatment is to induce mitochondrial biogenesis. Nicotinamide Riboside (NR) is an NAD+ booster which showed promising results in two mouse models of mitochondrial disorders. We describe an open label study to test the effect of NR for four weeks in eight individuals with m.3243A>G, m.3243A>T or …

The Effects of Vitamin B3 Supplement Therapy on Whole Body Metabolism in Monozygotic Twin Pairs
Tiivistelmä Lihavuus on yleistynyt viime vuosikymmenten aikana räjähdysmäisesti. Tämän myötä myös lihavuuden liitännäissairaudet, kuten tyypin 2 diabetes ja maksan rasvoittuminen, ovat lisääntyneet. Lihavuuden yhteydessä kudoksissa nähdään nikotiiniamidi adeniini dinukleotidi (NAD+) -molekyylin …

Chronic Gestational Inflammation: Comparisons of Obesity-Mediated and Preeclampsia-Mediated Placental Inflammation using Transcriptomic and Histological Methods
Several obstetrical complications, including maternal obesity (MO) and preeclampsia (PE), are associated with states of chronic gestational inflammation and poor pregnancy outcomes. However, commonalities and/or differences from these divergent chronic inflammatory insults on placental development …
