Single protein targeted as the root biological cause of several childhood psychiatric disorders
Date:10/31/2012

A new research discovery has the potential to revolutionize the biological understanding of some childhood psychiatric disorders. Specifically, scientists have found that when a single protein involved in brain development, called "SRGAP3," is malformed, it causes problems in the brain functioning of mice that cause symptoms that are similar to some mental health and neurological disorders in children. Because this protein has similar functions in humans, it may represent a "missing link" for several disorders that are part of an illness spectrum. In addition, it offers researchers a new target for the development of treatments that can correct the biological cause rather than treat the symptoms. This discovery was published in November 2012 print issue of The FASEB Journal.

"Developmental brain disorders such as schizophrenia, hydrocephalus, mental retardation and autism are among the most devastating diseases in children and young adults," said Dusan Bartsch, Ph.D., a researcher involved in the work from the Department of Molecular Biology at the Central Institute of Mental Health at the University of Heidelberg in Mannheim, Germany. "We hope that our findings will contribute to a better understanding, and in the end, to better treatments for these disorders."

Bartsch and colleagues made this discovery using mice with the SRGAP3 protein inactivated. Then they conducted several experiments comparing these mice to normal mice. The mice with inactive SRGAP3 showed clear changes in their brains' anatomy, which resulted in altered behavior similar to certain symptoms in human neurological and psychiatric diseases. An involvement of SRGAP3 in different brain disorders could indicate that these disorders are possibly connected, as SRGAP3 is a key player in brain development. These different disorders could be connected via the SRGAP3 protein because they all emerge from disturbed development of the nervous system.

"Since Freud put biological psychiatry on the map, we've slowly increased our understanding of how mental health is dictated by chemistry," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "Eventually we'll understand the complex biology underlying most psychiatric illnesses, from genes to proteins to cell signaling to overt behaviors. Along the way, as in this report, we're likely to find single targets close to the roots of apparently different mental illnesses."

The FASEB Journal is published by the Federation of the American Societies for Experimental Biology (FASEB). It is among the most cited biology journals worldwide according to the Institute for Scientific Information and has been recognized by the Special Libraries Association as one of the top 100 most influential biomedical journals of the past century. FASEB is composed of 26 societies with more than 100,000 members, making it the largest coalition of biomedical research associations in the United States. Celebrating 100 Years of Advancing the Life Sciences in 2012, FASEB is rededicating its efforts to advance health and well-being by promoting progress and education in biological and biomedical sciences through service to our member societies and collaborative advocacy.
