Apoptosis inhibition mitigates aging effects in Drosophila melanogaster

Research output: Contribution to journalArticlepeer-review

Abstract

Aging is a natural biological process that results in progressive loss of cell, tissue, and organ function. One of the causing factors of the aging process is the decrease in muscle mass, which has not been fully verified in Drosophila. Apoptotic cell death may result in aberrant cell loss and can eventually diminish tissue function and muscle atrophy. If so, inhibition of apoptosis may prolong longevity and reduce motor function and muscle mass decline with age in Drosophila flies. Here, we used Drosophila melanogaster as study material, and induced the overexpression of Drosophila inhibitor of apoptosis protein 1 gene to inhibit apoptosis, and investigated the effect of apoptosis inhibition on the longevity and age-related declines in flight and climbing ability and muscle mass. As a result, the inhibition of apoptosis tended to mitigate the aging effects and prolonged longevity and reduced climbing ability decline with age. The current study suggests that apoptosis inhibition could mitigate the aging effects in D. melanogaster. Although such effects have already been known in mammals, the current results suggest that the apoptosis may play a similar role in insects as well.
