Identification Of Novel Molecular-Genetic Pathways Regulating The Development Of Subpallial Derivatives, David Tischfield Jan 2016

Identification Of Novel Molecular-Genetic Pathways Regulating The Development Of Subpallial Derivatives, David Tischfield

Publicly Accessible Penn Dissertations

The embryonic subpallium produces many different neuronal cell types present throughout the adult telencephalon, including striatal medium spiny neurons (MSN) and cortical interneurons. Dysfunction of either cell type leads to neurological and psychiatric disorders including schizophrenia, epilepsy, and Tourette’s syndrome. Thus, understanding the molecular pathways that regulate their development and function has important implications for understanding disease pathogenesis. This work describes novel methods and genetic factors that expand our ability to characterize the development and function of two major subpallial derivatives: cortical interneurons and striatal MSN. The first part of this thesis characterizes a novel enrichment method for producing ...


Contextual Insights Into The Rett Syndrome Transcriptome, Brian Scott Roosevelt Johnson Jan 2016

Contextual Insights Into The Rett Syndrome Transcriptome, Brian Scott Roosevelt Johnson

Publicly Accessible Penn Dissertations

Mutations in MECP2 are responsible for Rett syndrome (RTT), a severe X-linked neurological disorder characterized by loss of developmental milestones, intellectual disability and motor impairments. However, molecular insight into how these mutations affect the neuronal transcriptiome, disrupt neuronal function and contribute to RTT is impeded by the cellular heterogeneity of the mammalian brain. A comparison between gene expression changes in the striatum, hypothalamus, and cerebellum of MeCP2-null mice revealed that gene expression changes are distinct between different brain regions, which suggests that MeCP2 function should be understood in a cell type-dependent context. To accomplish this task, I generated and phenotypically ...
