摘要
The study has shown that both functional gene knockout Sodl and Sod2 and their overexpression in neurons and glial tissue increase the sensitivity of Drosophila melanogaster to oxidative stress (OS) conditions. The lowest survival rate was only 20.5% in insects with Sod2 knockout in neurons. Comparative analysis of the survival curves showed that adults with altered tissue-specific expression of the studied genes had reduced average and maximum life span. Under OS conditions induced by 5% hydrogen peroxide the life spans of wild type Oregon R and transgenic insects were significantly reduced. Altered Sod gene expression in glial tissue leads to degenerative changes in Drosophila brain at the young age. During the aging of insects and the action of pro-oxidants increasing of neurodegenerative phenotype is observed.
