Roles Of Autism Gene Arid1b In Murine Brain Development And Behavior, Amanda L. Smith

Theses & Dissertations

Autism spectrum disorder (ASD) and intellectual disability (ID) are highly prevalent neurodevelopmental disorders characterized by social and communication deficits, stereotyped behaviors, cognitive dysfunction, and deficits in adaptive behaviors. The pathogenesis underlying these disorders remains unknown, and thus no pharmacologic or genetic therapies are currently available. Recent progress in the field has shown that haploinsufficiency of the AT-rich interactive domain-containing 1B (ARID1B) gene is a genetic cause of ASD and ID. Our lab recently developed an Arid1b knockout mouse model to better study its role in the pathogenesis of these disorders. One theory regarding the cause of neurodevelopmental disorders …

Neurodevelopmental Defects Associated With Gestational Exposure To Low Levels Of Dbp In Mice, Françoise Sidime

Dissertations, Theses, and Capstone Projects

The etiology of autism is thought to involve the complex interplay among genetic and environmental factors. Patterns of inheritance suggest an epigenetic component to the development of autism. A variety of environmental risk factors are known to induce epigenetic changes in DNA, affecting many genes including those autism-associated genes (AAG). The plasticizer dibutyl phthalate (DBP; CAS 84-74-2) is a developmental and reproductive toxin that causes a broad range of birth defects resulting in neurological impairments.

To date, although the effect of DBP as an endocrine and a reproductive disruptor are established, there are only few studies that address the effects …
