Variation at a central metabolic gene influences male fruit fly lifespan [Phys]

The overexpression of an important gene that regulates energy metabolism can cause a severe shortening of lifespan in male fruit flies but has only a small negative effect on lifespans of female fruit flies, according to new research from North Carolina State University. The findings, which involve metabolic genes and pathways that are important in humans and other animals, shed more light on sex-specific differences between male and female lifespans.
