Abstract |
In Drosophila melanogaster, the Sir2 gene and four Sir2-like genes have been found to be homologous to yeast SIR2 genes. To examine whether the fly Sir2, CG5216, and two Sir2-like genes, CG5085 and CG6284, affect life span, we suppressed their expression using RNAi. Decreased expression of the Sir2 and Sir2-like genes in all cells caused lethality during development. Suppression of the Sir2 in neurons and ubiquitous silencing of the Sir2-like genes shortened life spans. The effects were severer at 28 degrees C than at 25 degrees C. These results suggest that Sir2-like genes as well as Sir2 are involved in the regulation of life span in Drosophila. |
