Chromatin Organizer Ctcf In Brain Development And Behaviour, Adrienne Elbert Jan 2018

Chromatin Organizer Ctcf In Brain Development And Behaviour, Adrienne Elbert

Electronic Thesis and Dissertation Repository

Chromatin architecture is an important regulator of gene expression, which dictates development. Mutations in one copy of the CTCF chromatin organizer gene cause intellectual disability and autism. Polymorphisms in CTCF have also been associated with increased risk for schizophrenia, a condition that overlaps in biological etiology with autism and intellectual disability. In this thesis, we sought to understand the role of CTCF in neurodevelopment using brain-specific conditional knockout and heterozygote mouse models. Using the Ctcf-null animals, we identify a cell-autonomous role for CTCF in regulating cortical interneuron development in the medial ganglionic eminence (MGE) through the transcriptional control of …
