A ribose-functionalized NAD+ with unexpected high activity and selectivity for protein poly-ADP-ribosylation. [PDF]

open access: yes, 2019
Nicotinamide adenine dinucleotide (NAD+)-dependent ADP-ribosylation plays important roles in physiology and pathophysiology. It has been challenging to study this key type of enzymatic post-translational modification in particular for protein poly-ADP ...

Intestinal Fut2 deficiency exacerbated alcohol‐related liver disease by disrupting nicotinamide metabolism

open access: yesClinical and Translational Medicine, Volume 15, Issue 8, August 2025.
Loss of intestinal epithelial fucosylation exacerbates alcohol‐related liver injuries. Intestinal epithelial deletion of Fut2 disrupts nicotinamide (NAM) metabolism due to the decline in bacterial nicotinamidase (PncA). Supplemented with pncA overexpressed E.coli to restore gut PncA levels can improve liver damage in alcohol‐induced intestinal ...

Preferential utilization of NADPH as the endogenous electron donor for NAD(P)H:quinone oxidoreductase 1 (NQO1) in intact pulmonary arterial endothelial cells [PDF]

open access: yes, 2009
The goal was to determine whether endogenous cytosolic NAD(P)H:quinone oxidoreductase 1 (NQO1) preferentially uses NADPH or NADH in intact pulmonary arterial endothelial cells in culture.

Maternal Circulatory NAD Precursor Levels and the Yolk Sac Determine NAD Deficiency‐Driven Congenital Malformation Risk

open access: yesThe FASEB Journal, Volume 39, Issue 14, 31 July 2025.
Maternal circulatory L‐tryptophan (TRP) and nicotinamide (NAM) levels are proportional to dietary TRP intake. Yolk sacs, but not embryos, perform NAD de novo synthesis. This study explores the exchange of NAD precursors between mother and conceptus, and NAD generation in conceptal tissues via the NAD de novo synthesis (blue) or salvage (red) pathways ...

Effects of Aging on Glucose and Lipid Metabolism in Mice

open access: yesAging Cell, Volume 24, Issue 4, April 2025.
Lien et al. report a characterization of metabolism with aging across three different strains of mice. They find that glucose metabolism is robust during healthy aging; however, aging tissues exhibit evidence of upregulated fatty acid and sphingolipid metabolism reactions that regenerate NAD+ from NADH.

Structural dynamic modification of vibrating systems [PDF]

open access: yesApplied and Computational Mechanics, 2007
Vibration and acoustic requirements are becoming increasingly important in the design of mechanical structures. The need to vary the structural behaviour to solve noise and vibration problems occurs at design or prototype stage, giving rise to the so ...
