Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

...ms first appear late in childhood live longer, but life expectancy remains greatly decreased. Although Pompe disease is a relatively rare disease, it is but one of a group of related "lysosomal storage diseases," which in total occur in about one in 5,000 births. The current study is part of a large, col...

BRCA1 causes ovarian cancer through indirect, biochemical route

...en who have regular menstrual cycles through their life without interruption by pregnancy or oral contraceptive use are at highest risk for developing sporadic ovarian cancer," Dubeau explains. "So we had some clues that the cells that control the menstrual cycle-the ovarian granulosa cells-have an influe...

Poplar trees redirect resources in response to simulated attack

...will be available to help the plant spring back to life once the attack has passed. Using the techniques developed at Brookhaven, we now have a way to find out." To simulate an insect attack, the scientists painted a solution of jasmonic acid, a chemical messenger that plants produce in response to vario...

Vital step in cellular migration described by UCSD medical researchers

...the body's own tissue." From the genesis of human life to birth and beyond, cell migration is a complex, extremely important process that is not completely understood by researchers. In order to move, a cell must be polarized so that the molecular processes at the front end and back end are different, le...
