We monitored TORC1 activity by examining autophagy and translation. The GFP-fused vacuolar protein LGG-1 marks autophagic vesicles.

In contrast, autophagy was reduced by knockdown of the S6 kinase RSKS-1, which increases translation downstream of TORC1 but also promotes autophagy (Scott et al., 2004).

Reductions in germline stem cell (GSC) number delay aging, presumably to preserve the organism during adversity (Kenyon, 2010). When the number of GSCs is usually reduced, DAF-16 accumulates in intestinal nuclei. The accompanying longevity extensions require DAF-16 and the ankyrin repeat protein KRI-1 (Kenyon, 2010). Several lines of evidence indicate that genetic interference with TORC1 or translation extends lifespan independently of the GSC pathway. Fecundity and presumably GSC.This differs from the effect of mutation (reduced IIS), which increases SKN-1 nuclear accumulation in worms maintained on OP50 (Tullet et al., 2008). et al., 2010; Kenyon, 2010; Panowski et al., 2007; Sheaffer et al., 2008; Vellai et al., 2003).
