SUMMARY:BE Seminar: "Promoting Appendage/Limb Regeneration in Jellyfish\, Drosophila\, and Mouse" (Lea Goentoro)
DESCRIPTION:This seminar will be held virtually on Zoom – check email for link or contact ksas@seas.upenn.edu. \nCan limb regeneration be induced? In this talk\, I will discuss our work to promote regeneration in animals with limited regeneration capacity. I will present our recent discovery of a strategy for inducing regenerative response in appendages\, which works across three species that span the animal phylogeny. In Cnidaria\, the frequency of appendage regeneration in the moon jellyfish Aurelia was increased by feeding with the amino acid L-leucine and the growth hormone insulin. In insects\, the same strategy induced tibia regeneration in adult Drosophila. Finally\, in mammals\, L-leucine and sucrose administration induced digit regeneration in adult mice\, including dramatically from mid-phalangeal amputation. The conserved effect of L-leucine and insulin/sugar suggests a key role for energetic parameters in regeneration induction. The simplicity by which nutrient supplementation can induce appendage regeneration provides a testable hypothesis across animals.
