Flame retardant linked to autism in genetically-susceptible animals
July 12, 2012 Researchers have found that exposure to a flame retardant chemical during development interacts with a known genetic mutation to impair learning and memory and decrease social behaviours in mice, in what is claimed to be the first study demonstrating that environmental contaminants and genetics can work together to create autism-like symptoms. The research is published in Human Molecular Genetics, and Chemical Watch reported the story.
A Research Strategy to Discover the Environmental Causes of Autism and Neurodevelopmental Disabilities April 25, 2012, Environmental Health PerspectivesExcerpt: Exploration of the environmental causes of autism and other NDDs has been catalyzed by growing recognition of the exquisite sensitivity of the developing human brain to toxic chemicals (Grandjean and Landrigan 2006). This susceptibility is greatest during unique “windows of vulnerability” that open only in embryonic and fetal life and have no later counterpart (Miodovnik 2011).
COMMON FLAME RETARDANT LINKED TO SOCIAL, BEHAVIORAL AND LEARNING DEFICITS Study highlights the interaction between epigenetics and genetics and exposure to a flame retardant in mice. February 16, 2012. Mice genetically engineered to be susceptible to autism-like behaviors that were exposed to a common flame retardant were less fertile and their offspring were smaller, less sociable and demonstrated marked deficits in learning and long-term memory when compared with the offspring of normal unexposed mice, a study by researchers at UC Davis has found. The researchers said the study is the first to link genetics and epigenetics with exposure to a flame retardant chemical. The research was published online in the journal Human Molecular Genetics. It was presented during a symposium on Feb. 18, at the annual meeting of the American Association for the Advancement of Science (AAAS) by Janine LaSalle, a professor in the Department of Medical Microbiology and Immunology in the UC Davis School of Medicine and the UC Davis Genome Center.
