Scientists collaborate to assess health of global environment

...Millennium Ecosystem Assessment program will issue its primary report on March 30 during press conferences in London, Washington, D.C., Tokyo, Beijing, New Delhi, Brasilia, Cairo, Nairobi and Rome. More than 2,000 scientists from 95 countries participated in the assessment and concluded that the environm...

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

... specialized DNA "promoter" region that restricted its activity to muscle. The investigators either injected the viral particles into the muscle or injected it intravenously in Pompe disease mice. Six weeks after muscular injection with the virus containing the muscle-restricted gene, mice exhibited hig...

Enzyme shown to help protect genomic stability

...trying to better understand how DNA is managed and its activity regulated. Histones are small proteins around which DNA is coiled to create structures called nucleosomes. Compact strings of nucleosomes, then, form into chromatin, the substructure of chromosomes. In many cases, when the DNA is tightly wra...

Vital step in cellular migration described by UCSD medical researchers

...actor sites for migration as the cell moves toward its intended target. If Rac were active throughout the cell, it would extend protrusions in all directions, in essence keeping the cell in one place. Until now, researchers have had limited understanding of the molecular mechanism that inhibits Rac acti...
