Howard Hughes Medical Institute researchers have harnessed a mobile gene from the cabbage looper moth and modified it for routine use to determine the function of genes in mice and other vertebrates. If the new tool works as they expect, it will speed understanding of genes involved in human biology and disease and accelerate the search for effective new therapies. The researchers report their study in the August 12, 2005, issue of the journal Cell. Certain genes or genetic elements, called...

New Haven, Conn. -- A collaborative project between American and Chinese researchers developed a way to study the function of genes in mice and man by using a moveable genetic element from moths, according to a report in the journal Cell. "We know how many genes are in the mammalian genome, but that does not tell us how they carry out their jobs," said senior author Tian Xu, Professor and Vice Chair of Genetics at Yale University School of Medicine and a Howard Hughes Medical Institute...

WOODS HOLE, MA - A January 2004 finding by biologists at the Josephine Bay Paul Center for Comparative Molecular Biology and Evolution added important evidence to the radical conclusion that a group of diminutive aquatic animals called bdelloid rotifers have evolved for tens of millions of years without sexual reproduction, in apparent violation of the rule that abandonment of sexual reproduction is a biological dead end. Now, MBL scientists are beginning to understand just what's different...

Researchers at the University of Minnesota Cancer Center and the National Cancer Institute (NCI), part of the National Institutes of Health, have discovered a new method that could accelerate the way cancer-causing genes are found and could lead to a more accurate identification of the genes, according to two studies in the July 14, 2005, issue of Nature*. The gene identification method was developed in genetically modified mice and utilized a piece of jumping DNA, called Sleeping Beauty....

LA JOLLA - Brains are marvels of diversity: no two look the same -- not even those of otherwise identical twins. Scientists at the Salk Institute for Biological Studies may have found one explanation for the puzzling variety in brain organization and function: mobile elements, pieces of DNA that can jump from one place in the genome to another, randomly changing the genetic information in single brain cells. If enough of these jumps occur, they could allow individual brains to develop in...
