Parasites ready to jump

...son activity. Professor Klaus Frstemann of the Gene Center of Ludwig-Maximilians-Universitt (LMU) in Munich and a team of researchers working with the fruitfly Drosophila melanogaster have now uncovered a new type of cellular defence that acts against DNA sequences present in high copy numbers inside the cell...

Tumor suppressor gene in flies may provide insights for human brain tumors

...rotein in the fly's brain, with a counterpart in mammals, that can apparently prevent brain tumors from forming. "Our data explicitly show that the fruitfly protein PP2A (protein phosphatase 2A) suppresses brain tumor formation and controls the balance of self-renewal and differentiation of neural stem cel...

Genetic based human diseases are an ancient evolutionary legacy

...olutionary processes. Although it was already known that many disease associated genes occur also in other organisms distant to humans, such as the fruitfly Drosophila or the round worm Caenorhabditis, the analysis of Domazet-Loo and Tautz shows now for the first time that this is systematically true for t...

Like father, like son: Attractiveness is hereditary

... in Current Biology, shows that attractiveness is hereditary. The research team, based on the University of Exeters Cornwall Campus, focused on the fruitfly Drosophila simulans. They paired up males and females at random and found the length of time it took for them to mate ranged from just two minutes to ...

Corals -- More complex than you?

...rnover times ?like fruit flies ?shed genes particularly fast. Corals which take at least 5years to reach sexual maturity (compared with the laboratory fruitfly whose generation lasts only 3-4 weeks), and which have long and overlapping generation times, may thus be a living ‘museum?of ancestral animal genes....

Brain region linked to fly slumber

...by Ravi Allada, assistant professor of neurobiology and physiology, shows that the so-called mushroom bodies are essential for sleep regulation in the fruitfly Drosophila melanogaster. (In the same issue, a second study, led by Amita Sehgal of the Howard Hughes Medical Institute, produced similar results usin...

Parkinson's disease mechanism discovered

... The researchers next studied whether enhancing activity of the mammalian Ytp1p counterpart, called Rab1, suppressed alpha-synuclein toxicity in the fruitfly Drosophila, the roundworm C. elegans and in cultures of rat neurons. Bonini and her colleagues tested the effect in fruitflies; co-author Guy Caldwell...
