Jump-starting growth signaling reverses microcephaly in autism mouse model

A genetic therapy and an existing drug both restore typical brain size in mice missing DYRK1A, a top autism candidate gene, in the cerebral cortex, a new study shows. The animals typically have smaller brains than controls.

Growth factor rescues neurons made from boys with Rett

Neurons derived from the skin cells of boys with Rett syndrome can help screen potential treatments for the disorder, suggest unpublished results presented yesterday at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

The case for using ‘prebiotics’

Prebiotics — nutrients that promote the growth of some beneficial gut bacteria — can influence brain chemistry and behavior. New findings suggest prebiotics as treatments for people with neurological disorders, say Sarkis Mazmanian and Gil Sharon.

No longer junk: Role of long noncoding RNAs in autism risk

Long pieces of RNA that do not code for protein have diverse and important roles in the cell and may contribute to autism risk, say Nikolaos Mellios and Mriganka Sur.

Molecular mechanisms: Rett gene boosts protein production

MeCP2, the protein mutated in Rett syndrome, is normally responsible for boosting the expression of a large number of genes. This finding, published 3 October in Cell Stem Cell, may explain why growth factors that promote protein production are able to reverse features of the syndrome in mice.

Existing drugs could treat Rett syndrome, studies suggest

Rett syndrome affects many cellular pathways, but correcting just one of these with drugs approved for other purposes may be enough to alleviate symptoms of the disorder. This was the message from two presentations Tuesday at the 2013 Society for Neuroscience annual meeting in San Diego.
