Check out the new article at @pnas.org (doi.org/10.1073/pnas...) for details, and also for an #ecological model how light-dependent #lifespan and #growth extension may have #adaptive value for organisms, balancing reproductive success and predator avoidance, and also #seasonal time. [6/7]

Strikingly, l-cry impacts on several hormonal pathways, including a co-expressed nuclear receptor: nr0b1/2. The gene is absent in ecdysozoans (flies, nematodes), but dax1, one of its counterparts in vertebrates, is linked to sexual development and #puberty onset even in #humans. [5/7]

We find that in mutant worms, sexual maturation is significantly delayed – when wild-type worms are already beginning to mature, l-cry mutants are still immature. So, the worm’s trick to #longevity is to stay longer “pre-puberty”... But what could be molecular mechanisms? [4/7]
