Spd

Symbol: Spd
Name: Spermidine

Function:
Natural polyamine

Observation:

Administration of spermidine extends lifespan of yeast, flies and worms and human immune cells. In yeast spermidine treatment triggers deacetylation of H3 through inhibition of histone acetylatranserfases, suppresses oxidative stress and necrosis. Altered acetylation of the chromatin results in upregulation of various autophagy-related genes and triggers autophagy [19801973].

In nematodes treatment with 0.2 mM spermidine extends mean and maximum lifespan of wild-type by 16 and 13% significantly (<0.005) as well as the mean and maximum lifespan in sir-2.1(ok434) by 12 and 11% significantly (<0.01).
