Akh | Adipokinetic hormone | 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 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].
Fat-body specific Akh RNAi results in increased spontaneous activity and a small but significant increase in lifespan upon AL [22768842].
Overexpression of Akh in a ubiquitousness manner enhances fat metabolism (significant increase in triglyceride synthesis and breakdown under AL), spontaneous activity (148% on AL and 154% on DR), and lifespan on AL (33%). However, despite and increase in movement under DR, lifespan is not increased under a restricted diet [22768842]. | Fruit fly |
Akt1 | CG4006 gene product from transcript CG4006-RA | RNA interference of Akt1 in intestinal stem cells, results in impaired regeneration of the intestinal epithelium and a short lifespan. In males and females on mean lifespan is 11.4% and 7.4% lower [20976250]. | Fruit fly |

Cbs | — | Ubiquitous or neuron-specific transgenic overexpression of Cbs enhances longevity in fully-fed animals. Cbs RNAi partially abrogates increased lifespan by DR, but has no effect on fully fed animals. Cbs upregulation is required for increased lifespan under low-nutrient conditions. Response of male flies to DR is muted in comparison with females. Adult-specific ubiquitous expression of Cbs is sufficient to increase female mean and maximum lifespan by 12 - 43% and 10%, respectively. Males, whose lifespan is relatively less affected by DR, exhibite a smaller, but still significant increase in lifespan by 7% upon Cbs overexpression. Neuronal overexpression also increases lifespan, albeit modestly (approximately 12% mean and 15% maximum lifespan extension), whereas overexpression in the fat body and in the gut has no effect [21930912]. | Fruit fly |
Cct1 | CTP:phosphocholine cytidylyltransferase 1 | Overexpression of Cct1 from a doxycycline-inducible promoter results in a 6 - 8% increase in mean lifespan (in the PdL x rtTA; Oregon-R x rtTA strain) [12620118].
Cct1 exhibits a non-coding region difference unique to animals under experimental evolution selected for longevity and is upregulated in head of animals that were selected for longevity at all ages beyond the day of eclosion [23106705]. | Fruit fly |
