Supplementary Figure 4: Kinetics of age-related decline of polyamines.
From: Restoring polyamines protects from age-induced memory impairment in an autophagy-dependent manner
Level of Spermidine (a) and Putrescine (b) in chronologically aging wild-type flies fed with food supplemented with 5mM spermidine (Spd5mM+), and compared to age-matched control flies (Spd–). Data are shown normalized to the level of respective polyamines found in 1-day old (1d) flies on Spd– food (or Spd–, 1d; n=3 for all data; F=19.32 for (a) and F=16.31 for (b) respectively; one-way-ANOVA with Bonferroni correction). *: p<0.05; ns: p>0.05, not significant; all values are mean ± SEM.
