MetabolomicsHydrolyzing NAD to NMN and AMP by SelO is required for mitochondria homeostasis

The regulation of mitochondrial nicotinamide adenine dinucleotide (mNAD) is crucial for numerous life processes. However, until now, no metabolic reaction responsible for downregulating mNAD has been identified. Through in silico screening of potential NAD-binding proteins, we discovered a previo...

MetabolomicsEpistasis-driven identification of SLC25A51 as a regulator of human mitochondrial NAD import
About a thousand genes in the human genome encode for membrane transporters. Among these, several solute carrier proteins (SLCs), representing the largest group of transporters, are still orphan and lack functional characterization. We reasoned that assessing genetic interactions among SLCs may be a...

MetabolomicsNiacin restriction with NAMPT-inhibition is synthetic lethal to neuroendocrine carcinoma (Mouse NAD targeted time-course)

NAMPT plays a major role in NAD biosynthesis in many cancers and is an attractive potential cancer target. However, factors dictating therapeutic efficacy of NAMPT inhibitors (NAMPTi) are unclear. We report that neuroendocrine phenotypes predict lung and prostate carcinoma vulnerability to NAMPTi...

MetabolomicsNAD+ augmentation restores mitophagy and limits accelerated aging in Werner syndrome (Intracellular UPLC-MS assay)

Metabolic dysfunction is a primary feature of Werner syndrome (WS), a human premature aging disease caused by mutations in the gene encoding the Werner (WRN) DNA helicase. WS patients exhibit severe metabolic phenotypes, but the underlying mechanisms are not understood, and whether the metabolic ...

ProteomicsCysteine oxidation as a regulatory mechanism of Arabidopsis plastidial NAD-dependent malate dehydrogenase
Malate dehydrogenases (MDHs) catalyze a reversible NAD(P)-dependent-oxidoreductase reaction that plays an important role in central metabolism and redox homeostasis of plant cells. Recent studies suggest a moonlighting function of plastidial NAD-dependent MDH (plNAD-MDH) in plastid biogenesis, indep...

MetabolomicsResting natural killer cell homeostasis relies on tryptophan/NAD+ metabolism and HIF-1α

Natural killer (NK) cells are forced to cope with different oxygen environments even under resting conditions. The adaptation to low oxygen is regulated by oxygen-sensitive transcription factors, the hypoxia-inducible factors (HIFs). The function of HIFs for NK cell activation and metabolic rewir...

MetabolomicsNicotinamide Riboside is Uniquely Bioavailable in People and Mice
Nicotinamide riboside (NR) is in wide use as an NAD+ precursor vitamin. Here we conducted experiments to determine the time and dose-dependent effects of NR on blood, liver and heart NAD+ metabolism in people and mice. We report that human blood cell NAD+ can rise as much as 2.7-fold with a single d...

TranscriptomicsNicotinamide mononucleotide, a key NAD+ precursor, treats the pathophysiology of diet- and age-induced diabetes
Type 2 diabetes (T2D) has become an epidemic in our modern lifestyle, likely due to calorie-rich diets overwhelming our adaptive metabolic pathways. One such pathway is mediated by nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in mammalian NAD+ biosynthesis, and the NAD+-...
