    Akh knockdown Knockdown of the adipokinetic hormone (Akh) by RNAi (with an RU486-inducible and ubiquitously expressing Actin 5C-GS Gal4 strain) does not by itself affect lifespan, but significantly inhibits the DR-dependent increase in lifespan across a range of yeast concentrations in both females and males. While control females and males exhibit a 113%/22% increase in lifespan under DR, upon Akh inhibition there was a significant reduction in lifespan extension with DR (52%/5%). Global Akh knockdown reduces starvation resistance by 24% upon DR, but no significant change upon AL. Also Akh RNAi repressed the DR-dependent increase in cold-stress resistance. Fat body and neuronal-specific inhibition of Akh by using RU486-inducible S(1)106-GS-Gal4 and Elav-GS-Gal4 enhancer traps, respectively, does not reduce lifespan extension upon DR. But, muscle-specific inhibition of Akh using RU486-inducible muscle enhancer trap (Mhc-GS-Gal4) reduces the DR-dependent increase in lifespan. While control exhibit a 47.2% lifespan extension, animals with muscle-specific Akh inhibition fails to result in any increase upon DR (i.e. completely blocked the DR lifespan extension). Muscle-specific Akh inhibition diminishes the increase in triglyceride synthesis and breakdown present normally under DR. A significant reduction in lifespan extension also occurs with a noninducible muscle driver (Mhc-Gal4). Controls on DR exhibit significant higher levels of spontaneous activity compared to Akh RNAi-inhibited animals at all ages. Akh inhibition reduces the protective effect of DR on age-related decline in muscle function/activity [22768842]. Fly

    CG4389 knockdown Muscle specific RNAi knockdown of CG489 which reduces its mRNA levels by 25-35%, significantly reduces the DR-dependent lifespan extension. CG4389 RNAi animals exhibit only 20% increase while controls display an lifespan increase by 123% upon DR [22768842]. Fly
    Surf1 knockdown Surf1 knockdown results in larval lethality. However, knockdown in the central nervous system (CNS) not only bypasses the larval lethality but it results in an increase in maximum lifespan of about 20-30% [16172499]. Fly +20 to +30
    CG7834 knockdown Muscle specific RNAi knockdown of CG7834 which reduces its mRNA levels by 25-35%, significantly reduces the DR-dependent lifespan extension. CG7834 RNAi animals exhibit only a 14% increase compared to the 55% lifespan-increase in controls upon DR [22768842]. Fly

    14-3-3epsilon mutation Loss of 14-3-3ε results in increased stress-induced apoptosis, growth repression and extended lifespan of flies, in a foxo-dependent manner. Mean lifespan of males and females is increased by 25% and 49%, respectively. Increased 14-3-3ε expression also reverts foxo-induced growth defects. No effect of lifespan is observed when overexpressing 14-3-3ε in adipose tissue, indicating that endogenous foxo activity in this tissue is low under normal conditions [18665908]. Fly +25 to +49
