NAD+ Research
Cellular Metabolism Coenzyme
Research area: cellular metabolism
Nicotinamide adenine dinucleotide (NAD+) is a coenzyme present in all living cells and central to hundreds of enzymatic reactions. Research interest has surged due to its observed decline with aging and its role in longevity-associated signaling pathways. NAD+ precursors such as NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are actively studied.
Research Areas
Cellular Energy Metabolism
NAD+ is an essential cofactor in the citric acid cycle and oxidative phosphorylation. Research investigates how NAD+ availability influences mitochondrial electron transport chain efficiency and cellular ATP production in aging and disease contexts.
Sirtuin Activation Research
Sirtuins (SIRT1–7) are NAD+-dependent deacetylases linked to aging, inflammation, and metabolic stress. Research explores how NAD+ precursors (NMN, NR) may support sirtuin signaling activity and downstream longevity-associated pathway research.
DNA Repair Signaling (PARP Pathway)
PARP enzymes consume NAD+ during DNA repair processes. Research examines the interplay between PARP activity, NAD+ availability, and genomic maintenance signaling — and whether NAD+ supplementation strategies affect DNA repair pathway capacity.
Circadian Rhythm & Metabolic Clock
Studies investigate NAD+ oscillations in the context of circadian rhythm signaling and their relationship to CLOCK gene expression, SIRT1 activity cycles, and metabolic clock pathway research.
Neuroprotective Pathway Research
Research examines NAD+'s role in neuronal energy supply, SIRT3 mitochondrial signaling in neurons, and potential neuroprotective pathway investigations in age-related neurological research.
Cellular metabolism and longevity research. NMN and NR are dietary supplement forms; IV/injectable NAD+ is investigational in clinical settings.
