Silencing of NAMPT leads to up-regulation of insulin receptor substrate 1 gene expression in U87 glioma cells

Endocrine Regulations, 2020
Objective. The aim of the present study was to investigate the effect of adipokine NAMPT (nicotinamide phosphoribosyltransferase) silencing on the expression of genes encoding IRS1 (insulin receptor substrate 1) and some other proliferation related ...

Crystal structure of human nicotinic acid phosphoribosyltransferase

FEBS Open Bio, 2015
Nicotinic acid phosphoribosyltransferase (EC 2.4.2.11) (NaPRTase) is the rate‐limiting enzyme in the three‐step Preiss–Handler pathway for the biosynthesis of NAD.

Discovery of potential visfatin activators using in silico docking and ADME predictions as therapy for type 2 diabetes

Beni-Suef University Journal of Basic and Applied Sciences, 2018
Visfatin (Nicotinamide phosphoribosyltransferase) is an adipokine implicated in mediating insulin resistance and exhibiting insulin mimetic effect and therefore represents a druggable target for diabetes therapy.

Nicotinamide phosphoribosyltransferase may be involved in age-related brain diseases. [PDF]

PLoS ONE, 2012
Nicotinamide phosphoribosyltransferase (NAMPT) is a key enzyme for nicotinamide adenine dinucleotide (NAD) biosynthesis, and can be found either intracellularly (iNAMPT) or extracellularly (eNAMPT).

Maintenance of NAD+ Homeostasis in Skeletal Muscle during Aging and Exercise

Cells, 2022
Nicotinamide adenine dinucleotide (NAD) is a versatile chemical compound serving as a coenzyme in metabolic pathways and as a substrate to support the enzymatic functions of sirtuins (SIRTs), poly (ADP-ribose) polymerase-1 (PARP-1), and cyclic ADP ribose

Porcine placental extract increase the cellular NAD levels in human epidermal keratinocytes

Scientific Reports, 2022
Nicotinamide adenine dinucleotide (NAD) is an essential cofactor for numerous enzymes involved in energy metabolism. Because decreasing NAD levels is a common hallmark of the aging process in various tissues and organs, maintaining NAD levels has ...

Cancer cell metabolic plasticity allows resistance to NAMPT inhibition but invariably induces dependence on LDHA

Cancer & Metabolism, 2018
Background Inhibitors of nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in NAD+ biosynthesis from nicotinamide, exhibit anticancer effects in preclinical models.

Engineering Aging: Approaches to Model and Deconstruct Biological Complexity

Advanced Materials, EarlyView.
The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.

Supplementation of Nicotinic Acid with NAMPT Inhibitors Results in Loss of In Vivo Efficacy in NAPRT1-Deficient Tumor Models

Neoplasia: An International Journal for Oncology Research, 2013
Nicotinamide adenine dinucleotide (NAD) is a metabolite essential for cell survival and generated de novo from tryptophan or recycled from nicotinamide (NAM) through the nicotinamide phosphoribosyltransferase (NAMPT)-dependent salvage pathway ...
