InterventionNicotinic Acid
Alternate Name
OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeNo effect on life-span
Allele TypeN/A
StrainW303, PSY316
DescriptionSupplementation of media with 5 mM or 50 mM nicotinic acid has no detrimental effect on life-span (Bitterman et al., 2002).
Gene Function
Other PhenotypesUnlike nicotinamide, nicotinic acid does not inhibit the NAD-dependent histone deacetylase activity of SIR2.
