Scientists create mouse models of chromosome 16 defects

by  /  13 December 2010

Two independent groups have created mice that have deletions or duplications in a large section of chromosome 16. Each team has produced an animal with a different set of features, some of which — such as large head size and repetitive behaviors — are reminiscent of people with autism.

Molecular mechanisms: New pathway for fragile X treatment

by  /  2 December 2010

Inhibiting the ERK1/2 pathway — which regulates the synthesis of other proteins — can rescue some of the effects of fragile X syndrome, according to a study published 17 November in the Journal of Neuroscience. The ERK pathway could provide a novel target for fragile X therapies.

Molecular mechanisms: Researchers light up interactions between neurons

by  /  30 November 2010

Researchers have developed a technique to detect interactions in live neurons between neuroligins and neurexins — two proteins known to bind at the junction between neurons, according to a study published 29 October in Cell.
