This week’s podcast is inspired by a new study in PNAS thatlooked at the role of methylation of the oxytocin receptor in social behavior in people without autism.  Together with studies of the brains of people with autism, it suggests that filling the brains with oxytocin may not be the best approach for treating social impairments.  Instead, compounds that turn on or turn off the genes that control oxytocin may be more appropriate, and it also may help explain variability in why some people respond to oxytocin treatment, and why others do not.   Also, scientific technology has a new way of studying the influence of the environment on brain development.

What was impactful this year in autism research? This last podcast of 2015 explores the year of the female, highlighting the relatively new exploration into what makes females with ASD different and what they can tell us about everybody with autism and their families.  Some of what is discussed was highlighted in other podcasts, but not all of it.   The summary is organized so that what may initially be interpreted as small, nonsignificant discoveries, are viewed as progress.  Everything from genetics to getting laws passed is included.

On Thursday October 1st, Autism Science Foundation, Autism Speaks and the Escher Fund for Autism co-organized an online symposium which examined the possibility that early mutations in cells that pass along genetic information from generation to generation (sperm and egg and cells that make the sperm an egg) has a role in the causes of autism.  This symposium is on the ASF podcast feed, but a quick summary is presented on this week’s podcast.  Jill Escher from the Escher Fund for Autism and Mat Pletcher from Autism Speaks provide their perspective.  Also, a quick rundown on the study that caused so much monkeying around in the press.
