Genetics: RNA not always a faithful copy of DNA

by  /  14 June 2011

Researchers have upended a central tenet of biology by showing that there are more than 10,000 sites in the human genome where RNA sequences do not match the DNA sequences from which they are transcribed. The findings were published 19 May in Science.

Solving the complex causes of a multi-hit disorder

by ,  /  7 June 2011

What’s known about the genetics of autism supports the ‘snowflake’ hypothesis — that the molecular underpinnings of disease are essentially unique from individual to individual — says human geneticist Brett Abrahams.

Molecular mechanisms: Placenta influences brain development

by  /  31 May 2011

The placenta regulates the levels of the neurotransmitter serotonin in the brains of mice at a key stage in embryonic development, according to a study published 21 April in Nature. The results suggest that the fetal environment can influence the long-term mental health of children, including whether they later develop autism or schizophrenia.

Cognition and behavior: Serotonin pathway affects mouse behavior

by  /  22 February 2011

Mice that lack the gene for integrin β3, or ITGB3 — which regulates the levels of serotonin in the blood — groom themselves frequently and show less interest in stranger mice compared with controls, according to a study published in February in Autism Research as part of a special issue on mouse models in autism.
