Guarente → NAD Metabolism: the sirtuin-NAD bridge
Leonard Guarente's link to NAD Metabolism (0.99 confidence) rests on evidence that he helped make sirtuins and NAD biology unavoidable in longevity research; three nodes overlap between his graph neighbors and the term's cluster, suggesting a bridge role.
Guarente "helped make sirtuins and NAD biology unavoidable in longevity research," per the stored evidence. His link to NAD Metabolism (nicotinamide adenine dinucleotide) carries 0.99 confidence. The term covers a biochemical pathway: NAD synthesis, cellular availability, redox balance, and the signaling roles of NAD metabolites.
Guarente's graph neighbors: sirtuin signaling, caloric restriction, mTOR signaling, resveratrol, rapamycin, metformin, NAD boosters, nicotinamide riboside (NR). The term NAD Metabolism clusters with different nodes: nicotinamide mononucleotide (NMN), NR, NAD boosters, the company MetroBiotech, the DTL project, researcher Martin Borch Jensen. Three nodes appear in both: sirtuin signaling, NR, and NAD boosters.
Our hypothesis: the overlap reflects Guarente's position as a bridge between sirtuin research and the NAD-supplement space. The graph data does not confirm this directly; it is our reading of the link structure.
Impact score: 38.5.

🔬 NAD Metabolism
The edge captures a clear intellectual lineage: one researcher's mechanistic work on sirtuins and caloric restriction created the vocabulary and commercial ecosystem around NAD metabolism, visible through the neighbor clusters on both endpoints.
