Aging Cell
More RNA from jumping DNA was not linked to shorter life in flies
Experiments in three fruit fly species challenged the idea that jumping DNA concentrated on the Y chromosome helps explain males’ shorter lives.Experiments in three fruit fly species challenged the idea that jumping DNA concentrated on the Y chromosome helps explain males’ shorter lives.
Fly studyMechanisms
Who was studiedMale and female Drosophila flies
What changedHigher RNA levels from jumping DNA were not consistently linked to shorter male lifespan across fly strains
The catchDifferent sampling ages for older males and females could distort RNA comparisons
