Extreme anti-oxidant protection against ionizing radiation in bdelloid rotifers

Abstract: Bdelloid rotifers, a class of freshwater invertebrates, are extraordinarily resistant to ionizing radiation (IR). Their radioresistance is not caused by reduced susceptibility to DNA double-strand breakage for IR makes double-strand breaks (DSBs) in bdelloids with essentially the same efficiency as in other species, regardless of radiosensitivity. Instead, we find that the bdelloid Adineta vaga is far more resistant to IR-induced protein carbonylation than is the much more radiosensitive nematode Caenorhabditi… Show more

“…Mais une thérapie préventive serait bien préférable à cette thérapie réparatrice apportant de nouvelles protéines, car elle assurerait la pérennité du processus naturel de renouvellement du protéome en renforçant les voies de renouvellement des protéines (dégradation sélective par le protéasome, autophagosome, chaperons, et synthèse de novo). C'est exactement la stratégie choisie par l'évolution de la résilience des organismes robustes [8,9].…”

“…Nous avons récemment établi que chez les bactéries [8] et chez les animaux [9], la morbidité et la mortalité cellulaires corrèlent avec l'accumulation des protéines endommagées par oxydation. D'autre part, la mort cellulaire par irradiation est fonction non pas tant des dommages subis par l'ADN -support de l'information -que de ceux subis par les protéines effectrices [8,11].…”
