Control centers for genes rife with autism-linked DNA blips

by  /  3 August 2015

DNA sequences called enhancers — which boost the expression of genes from within or outside them — are enriched for genetic variants linked to autism, suggests a new study. The finding may help researchers understand how variants outside genes contribute to autism.

New method vets quality of antibodies for experimental use

by  /  15 July 2015

Researchers have devised a reliable technique for evaluating how well antibodies home in on specific molecules in scientific experiments. The new approach could take some of the guesswork out of studies that use antibodies to label and isolate proteins.

Buildup of gene tags may clarify timing of Rett syndrome

by  /  22 May 2015

A new study may help explain why the symptoms of Rett syndrome appear 6 to 18 months after birth. It suggests that the role of MeCP2, the protein missing in the syndrome, becomes more important as the brain matures.
