The maintenance of a proper NAD+ pool is essential for cell survival, and tumor cells are particularly sensitive to changes in coenzyme levels. In this view, the inhibition of NAD+ biosynthesis is considered a promising therapeutic approach.

Nicotinate Phosphoribosyltransferase of Yeast [PDF]
Abstract Nicotinate phosphoribosyltransferase from bakers' yeast has been purified about 1,000-fold; the purified material showed only one band on cellulose acetate electrophoresis (pH 5.0 and 8.6). In addition to 5-phosphoribosyl 1-pyrophosphate, adenosine triphosphate (ATP) or an analogous nucleotide is required for enzyme activity and the ...

Targeting cancer cells that are highly dependent on the nicotinamide adenine dinucleotide (NAD+) metabolite is a promising therapeutic strategy. Nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme catalyzing NAD+ production ...

Nicotinamide Phosphoribosyltransferase in Rheumatoid Arthritis [PDF]
Nicotinamide Phosphoribosyltransferase (Nampt) is a pleiotropic protein with multiple functions, including catalyzing a rate-limiting reaction of nicotinamide adenine dinucleotide (NAD) synthesis in a mammalian salvage pathway and mediating the innate immune system's inflammatory response.

The enzyme nicotinate phosphoribosyltransferase (NAPRT) mediates the rate-limiting step in NAD salvage pathway starting from nicotinic acid. Here the authors show that NAPRT can be detected extracellularly, binds to Toll like receptor 4, and activates NF-

Recurrent 2,8-Dihydroxyadenine Crystalline Nephropathy in Renal Allograft
Adenine phosphoribosyltransferase deficiency is a rare cause of crystalline kidney disease. We present a case of end-stage kidney disease secondary to crystal deposition from adenine phosphoribosyltransferase deficiency with immediate recurrence of the ...

NAD+ metabolism controls inflammation during senescence
We have recently discovered that nicotinamide adenine dinucleotide metabolism controls the pro-inflammatory senescence-associated secretory phenotype during cellular senescence.

Dihydroxyadenine stone with adenine phosphoribosyltransferase deficiency: A case report
Adenine phosphoribosyltransferase (APRT) deficiency is a rare autosomal recessive error of purine metabolism resulting in the generation of 2,8-dihydroxyadenine (DHA), a highly insoluble metabolite of adenine, which can cause radiolucent urolithiasis ...
