Yale University biologists said they have discovered a gene that guides protein building in fruit flies and hope it will help them learn more about cell growth in humans. Spyros Artavanis-Tsakonas, associate professor of biology at the New Haven, Conn., school, said the fruit fly gene produces a protein important to cell development, with striking similarities to a substance known as Epidermal Growth Factor, or EGF, found in humans and mice.
