Activation of transposable elements during aging and neuronal decline in Drosophila


Li, Wanhe; Prazak, Lisa; Chatterjee, Nabanita; Grüninger, Servan; Krug, Lisa; Theodorou, Delphine; Dubnau, Josh (2013). Activation of transposable elements during aging and neuronal decline in Drosophila. Nature Neuroscience, 16(5):529-531.

Abstract

We found that several transposable elements were highly active in Drosophila brain during normal aging. In addition, we found that mutations in Drosophila Argonaute 2 (Ago2) resulted in exacerbated transposon expression in the brain, progressive and age-dependent memory impairment, and shortened lifespan. These findings suggest that transposon activation may contribute to age-dependent loss of neuronal function.
