Assays for NAD+-Dependent Reactions and NAD+ Metabolites [PDF]

, 2018
Nicotinamide adenine dinucleotide (NAD+) is an essential redox cofactor and signaling molecule that controls the activity of enzymes involved in metabolism, DNA repair, and cellular survival, such as the PARPs, CD38, and the sirtuins. Here, we describe three methods for measuring the activity of these enzymes: the etheno-NAD+ assay measures NAD ...

Nicotinamide riboside and caffeine partially restore diminished NAD availability but not altered energy metabolism in Alzheimer's disease

Aging Cell, Volume 21, Issue 7, July 2022., 2022
Nicotinamide riboside (NR) and caffeine increase nicotinamide adenine dinucleotide (NAD), transiently modulate bioenergetic functions, and change the expression of NAD‐synthesizing, recycling, or degrading genes in dermal fibroblasts or induced pluripotent stem cell (iPSC)‐derived neural progenitors and astrocytes from late‐onset Alzheimer's disease ...

CD38 Drives Progress of Osteoarthritis by Affecting Cartilage Homeostasis

Orthopaedic Surgery, Volume 14, Issue 5, Page 946-954, May 2022., 2022
CD38 is a membrane‐bound protein. This study primarily implicates CD38 as an important regulator of chondrogenic differentiation. Inhibition of CD38 demonstrated protection against cartilage degeneration, which suggests that CD38 could be a potential therapeutic target for OA.

CD38 inhibitor 78c increases mice lifespan and healthspan in a model of chronological aging

Aging Cell, Volume 21, Issue 4, April 2022., 2022
The NADase CD38 plays a key role in age‐related NAD decline. The CD38 inhibitor 78c increases lifespan and healthspan of naturally aged male mice. The increase in median and maximal lifespan was about 10%. Abstract Nicotinamide adenine dinucleotide (NAD) levels decline during aging, contributing to physical and metabolic dysfunction.

Nicotinamide pathways as the root cause of sepsis – an evolutionary perspective on macrophage energetic shifts

The FEBS Journal, Volume 289, Issue 4, Page 955-964, February 2022., 2022
Increased IDO activity towards de novo nicotinamide synthesis is a hallmark of alternatively activated macrophages. IDO upregulation in alternatively activated macrophages may be an attempt to compensate for insufficient NAD availability. Manipulation of nicotinamide metabolism may shift macrophage metabolism, thereby providing a therapeutic approach ...

NAD+-dependent DNA ligases of Mycobacterium tuberculosis and Streptomyces coelicolor [PDF]

, 2003
Sequencing of the genomes of Mycobacterium tuberculosis H37Rv and Streptomyces coelicolor A3(2) identified putative genes for an NAD+-dependent DNA ligase. We have cloned both open reading frames and overexpressed the protein products in Escherichia coli.

Characterization of sand boils with grading entropy [PDF]

Zbornik Matice Srpske za Prirodne Nauke, 2012
Grain size and grain distribution by size are dominant factors determining soil behaviour. The shape and position of a grain distribution curve contain implicit information about the propensity of sand boiling or piping at flood conditions. The author
