Figure 3. Interplay between the germline and the soma in the regulation of longevity by ASH-2 complex deficiency.
In adult worms, longevity by deficiencies in the ASH-2 complex requires an intact germline with continuous egg production. It is possible that unknown ‘pro-longevity’ signals are emitted from the fertilized eggs when ASH-2 complex members are deficient, thereby delaying aging of the soma. KD: knock-down.
