| Research Abstract |
We investigated molecular mechanisms underlying reparation systems during rehydration process of anhydrobiosis in the sleeping chironomid. From microarray analysis, expressions of over 400 genes were specifically up-regulated in the process of rehydration. The process of desiccation and rehydration in anhydrobiosis should cause serious oxidative stress in the sleeping chironomid, so that their genomic DNAs and proteins must be injured during anhydrobiosis. During rehydration, expression of reparation enzymes for DNA and proteins, such as Rad51 and protein L-isoaspartyl methyltransferase (PIMT), may lead to successful resurrection from desiccated form
