A mild stress, hypergravity exposure, postpones behavioral aging in Drosophila melanogaster.

摘要: Flies were submitted to two weeks of hypergravity in a centrifuge (3 or 5 g), starting at the second day imaginal life, and their behavior (spontaneous locomotor activity, patterns movement, climbing activity) was observed from removal an older age; usual effects age on these behaviors generally observed. Hypergravity-kept flies had worse behavioral scores than those always kept 1 g. When they aged, got either similar better g flies, which indicates that aging may be slower. These results show mild stress such as hypergravity, has been previously shown increase longevity males resistance heat shock both sexes, is environmental manipulation postponing flies.
