Detailed Description
Statement
Reference

Expression of Prx3dsRNA.Scer\UAS using Scer\GAL4da.G32 produced a phenotype that was indistinguishable from controls in terms of developmental timing, fertility, physical activity levels, or life span. However, exposure of young (10-15 day old) or middle-aged (30-40 day old) flies to paraquat or hydrogen peroxide reveals small but significant decreases in resistance to oxidants.

There is a slight increase in apoptosis in Prx3dsRNA.Scer\UAS, Scer\GAL4da.G32 flies relative to controls.

Under normal conditions, expression of Prx3dsRNA.Scer\UAS using Scer\GAL4da.G32 in a Prx5EY02106 background shortens mean lifespan from 55-70 days to 12.8 days. The 'double mutant' flies appear normal for the first 9-11 days after eclosion, but then undergo a very rapid increase in mortality rate. In response to either hydrogen peroxide or paraquat treatment, the 'double mutant' exhibits diminished survivability similar to the Prx5EY02106 mutant.

Expression of Prx3dsRNA.Scer\UAS using Scer\GAL4da.G32 in a Prx5EY02106 background results in an accelerated pro-oxidizing shift in the redox state shortly before an early death: the GSH:GSSG ratio and protein sulfhydryl levels (measures of thiol homeostasis) decrease significantly. Other markers of oxidative stress or mitochondrial function are not affected notably.

Expression of Prx3dsRNA.Scer\UAS using Scer\GAL4arm.PS in a Prx5EY02106 background shortens median lifespan. This phenotype is not rescued by co-expression of CatScer\UAS.T:mito1.

Trxr-1+t10 substantially prolongs survivorship of flies expressing Prx3dsRNA.Scer\UAS using Scer\GAL4da.G32 in a Prx5EY02106 background, increasing survivorship by almost 60%. Trxr-1+t10 also restores sulfhydryl levels and the GSH:GSSG ratio in these flies.

Prx3dsRNA.Scer\UAS, Scer\GAL4arm.PS, Prx5EY02106 flies show a dramatic increase in apoptotic cells in thoracic muscles, digestive tract and oenocytes compared to single mutants and controls.
