This follow-on aged-mouse study examined gene-expression changes in the neurovascular unit after two weeks of NMN treatment.
Among 590 genes that differed with aging, 204 were reported to shift toward younger expression patterns after NMN. Pathway analyses were consistent with SIRT1 activation and mitochondrial, anti-inflammatory and anti-apoptotic mechanisms.
These are transcriptomic and animal-model findings. They help explain possible mechanisms but do not demonstrate human brain rejuvenation or cognitive benefit.
Key findings
590 neurovascular genes were identified as age-associated in the analyzed model.
204 of those genes shifted toward younger expression patterns after NMN treatment.
Pathway analyses predicted SIRT1-related, mitochondrial, anti-inflammatory and anti-apoptotic effects.
The work extends earlier neurovascular findings in aged mice.
What it cannot establish
Mouse study only.
Transcriptomic pathway predictions are not equivalent to demonstrated clinical effects.
Two-week intervention.
Gene-expression normalization does not establish human brain rejuvenation or disease prevention.
HealthspanX claim boundary: Transcriptomic changes in aged mice do not establish human brain rejuvenation, cognitive improvement, dementia prevention or anti-aging efficacy.
