The brains of people with autism show a distinct molecular signature that reflects alterations in how genes are pieced together and expressed.
The proposed guidelines would require scientists to destroy biological specimens if they don’t have the explicit consent of the participant for further use.
Methyl tags on DNA are distributed differently in postmortem brains from people with autism than in control brains, and mouse pups can inherit altered methylation from their older fathers, report two new studies.
People with autism show differences from controls in the levels of microRNAs, small noncoding bits of RNA, in the social and sound-processing parts of the brain. Unpublished results from the postmortem study were presented Wednesday at the 2013 Society for Neuroscience annual meeting in San Diego.
