GenDR Dietary Restriction Gene Manipulation: NNT1
Gene Information (Entrez Gene ID: 850991)
- Nicotinamide N-methylTransferase 1
- Saccharomyces cerevisiae (AnAge)
- Entrez Gene ID
Potential relevance to dietary restriction and ageing
Deletion of NNT1 decreases mean and maximum lifespan by 9 and 19%. 0.5% glucose DR extends the mean and maximum lifespan of NNT1 deletion mutants by 35 and 40%. Overexpression of NNT1 by 5-fold extends mean and maximum replicative lifespan by 18 and 23%, which is approximately of the same magnitude as the lifespan extension obtained from DR. DR in NNT1 overexpression mutant fails to significantly affect the lifespan and only results in extended mean lifespan by 12% and reduced maximum lifespan by 11% .
