Molecular mechanisms: Fragile X premutation proves toxic

by  /  18 June 2013

A mild form of the fragile X mutation produces an unusual protein that may trigger fragile X-associated tremor/ataxia syndrome, a neurodegenerative disorder, according to a study published 8 May in Neuron.

Molecular mechanisms: Neuroligin brackets neuronal junctions

by  /  15 January 2013

Neuroligin-2, an autism-linked protein, functions at both sides of neuronal junctions in fruit flies, according to a study published 7 November in The Journal of Neuroscience. The proteins have only been seen at the signal-receiving ends of these junctions in vertebrates.

Genetics: RNA improvisations altered in autism

by  /  9 October 2012

RNA editing, which creates multiple forms of a protein, is common among proteins involved in neuronal signaling, and may be abnormal in people with autism, according to a study published 7 August in Molecular Psychiatry.

Fruit fly reference helps link genes to traits

by  /  7 March 2012

Researchers have generated and sequenced almost 200 different strains of fruit flies, a widely used model organism, according to a study published 8 February in Nature. The resource they created, called the Drosophila Genetic Reference Panel, will enable researchers to link genetic variants with aspects of fly biology and behavior.

Looking at autism through the fruit fly

by  /  6 March 2012

The characteristics, interactions and roles of autism-associated genes in the fruit flies’ brain will help guide how we think about the same genes in humans, says Ralph Greenspan.

Fruit flies pin down autism candidates

by  /  17 November 2011

Looking at flies that express elevated levels of UBE3A, a gene that is duplicated in some people with autism, researchers have identified 81 proteins that may be linked to the disorder, according to unpublished results presented Tuesday at the 2011 Society for Neuroscience annual meeting in Washington, D.C.

New drug rescues function in fragile X syndrome

by  /  20 January 2011

A new drug appears to relieve symptoms of fragile X syndrome by blocking the over-production of a key protein in a subset of people with the disorder, according to a 6 January study in Science Translational Medicine.
