Allen Institute charts gene expression in brain development

by  /  17 November 2010

The Allen Institute for Brain Science has released whole-genome expression data from one-and-a-half adult human brains, and is gathering information from samples at different stages of development, from four weeks after conception to adulthood. The data were described at poster sessions Saturday and Tuesday at the Society for Neuroscience annual meeting in San Diego.

Deep sequencing questions role of imprinted genes in autism

by  /  8 July 2010

The mouse brain has more than 1,300 regions for which the copy from one parent is expressed more often than the one from the other parent, according to two studies published today in Science. These so-called imprinted genes have been proposed to cause some cases of autism, but the researchers say their findings do not support that theory.
