NAD+ / NMN
Sirtuin Response
NAD+ (Nicotinamide Adenine Dinucleotide) and its precursor NMN drive cellular ATP production, sirtuin activation, and DNA repair. Transcriptomic monitoring tracks key target genes to verify intracellular coenzyme loading and mitochondrial expansion.
Tracked Physiological Dimensions
On the Advanced Transcriptomics Dashboard, NAD+ and NMN activity is mapped across three primary bioenergetic and aging dimensions.
Metabolism & Cellular Bioenergetics
Monitors downstream sirtuin activation and Krebs cycle enzymatic efficiency.
Mitochondrial Function
Tracks PGC-1α upregulation and structural network mitochondrial adaptations.
Cellular Aging & Longevity Pathways
Measures DNA repair enzyme activation (PARP1) and chromatin stability indicators.
Activating NAD+-Dependent Enzymes
NAD+ levels decline precipitously with age, disabling the body's primary anti-aging enzymes (sirtuins) and DNA repair mechanisms (PARPs). Replenishing NAD+ pools via precursors like NMN or direct infusions provides cells with the cofactor required to activate these systems.
Transcriptomics reads this response directly. By monitoring sirtuin gene expression (SIRT1, SIRT3) and PARP1 activity, clinicians can verify that NAD+ replenishment is translating into active epigenetic repair and mitochondrial biogenesis.
Key Target Genes
Sirtuins 1 & 3 Deacetylation Signaling
NAD+-dependent enzymes that deacetylate histones and mitochondrial proteins to promote metabolic health.
PGC-1α Mitochondrial Biogenesis
Activated downstream of sirtuin signaling to drive organelle replication and respiratory transcription.
Poly(ADP-Ribose) Polymerase 1 DNA Repair
Utilizes NAD+ directly to repair single-strand DNA damage, preserving genome integrity.
Nicotinamide Phosphoribosyltransferase NAD+ Salvage Pathway
Rate-limiting enzyme that recycles nicotinamide back into NAD+; upregulated to maintain pool levels.
Expected mRNA Expression Timeline
A typical timeline showing how active gene expression signals evolve during an NAD+ or NMN therapy cycle.
Sirtuin Activation
Rapid upregulation of SIRT1 and SIRT3 transcripts showing systemic NAD+ coenzyme loading.
Salvage Enhancement
Peak expression of NAMPT salvage pathway and PGC-1α mitochondrial biogenesis factors.
Epigenetic Maintenance
Consolidated gains in cellular age indices and sustained DNA repair enzyme pathways.
