The “organic food” market is the fastest growing food sector, yet it is unclear whether organically raised food is nutritionally superior to conventionally grown food and whether consuming organic food bestows health benefits. In order to evaluate potential health benefits of organic foods, we used the well-characterized fruit fly Drosophila melanogaster as a model system.   Regular readers of this blog will no doubt have heard of Drosophila melanogaster, the fly that has played a key role in important discoveries about skin cancer, the innate immune system and the development of tissues, but we’ve never really given this tiny superstar of science enough prominence on this blog.

A quick and simple introduction to Drosophila melanogaster. What is it and why bother about it. Drosophila melanogaster is a fruit fly, a little insect about 3mm long, of the kind that accumulates around spoiled fruit. It is also one of the most valuable of organisms in biological research, particularly in genetics and developmental biology.

For Drosophila melanogaster a SOD3 was reported to exhibit a protective of Drosophila extracellular Cu Zn superoxide dismutase.

Many biologists have dreamed of a research organism that can be studied from many, if not all, perspectives.

The fruit fly, Drosophila melanogaster, may be just such an organism. Its genetics have been studied since the early s, starting in Thomas Hunt Morgan's fly rooms at Columbia and Caltech. Since then, numerous studies have used fruit Cited by: Identification of three mutations in the Cu,Zn-superoxide dismutase (Cu,Zn-SOD) gene with familial amyotrophic lateral sclerosis: transduction of human Cu,Zn-SOD into PC12 cells by HIV-1 TAT protein basic domain.
