Mouse study offers hope for correcting how autism disrupts brain
...> Full Article
Four teams of scientists, using resources supported in part by NIMH, have pinpointed two different sites in the genome, each conferring a different type of genetic risk for autism. At one site, risk genes appear to be inherited. At the other, risk stems from spontaneous mutations, not seen in the genetics of the parents. In both examples, evidence suggests the suspect genes are critical for development of brain circuits impaired in autism.

A new resource that identifies regions of the human genome that regulate gene expression may help scientists learn about and develop treatments for a number of human diseases, according to researchers at Duke's Institute for Genome Sciences & Policy (IGSP).

 | In the January 18th issue of Molecular Cell, Case Western Reserve University School of Medicine researcher Kristian E. Baker, Ph.D. challenges molecular biology's established body of evidence and widely-accepted model for nonsense-mediated messenger ribonucleic acid (mRNA) decay. With her collaborator, Ambro van Hoof, Ph.D. of The University of Texas Health Sciences Center, Baker directly tested the "faux 3' UTR" model and proved it could not explain how cells recognize and destroy deviant mRNA. This landmark discovery will redirect mRNA research and expand opportunities for new discoveries in understanding the cells' ability to protect itself from these potential errors. ...> Full Article |

Loss of a small portion of chromosome 16, known as 16p11.2, is significantly associated with autism report researchers from the University of Chicago Medical Center, the University of Illinois at Chicago, and the Roswell Park Cancer Institute in an article, published Dec. 21, 2007, online by the journal Human Molecular Genetics.

Johns Hopkins' McKusick-Nathans Institute of Genetic Medicine is one of two gene-hunting facilities in the nation to win a new $11.7 million four-year federal grant to rigorously sort out how such environmental factors as diet, exercise, stress and addictions interact with people's individual genetic makeup to affect their risk for disorders as wide-ranging as cancer, diabetes, tooth decay and heart disease.
