Role Of The Swi/Snf Chromatin Remodelling Complex In The Axon Development Of The Drosophila Mushroom Body, Melissa C. Chubak
Electronic Thesis and Dissertation Repository
The SWI/SNF complex is an evolutionarily conserved ATP-dependent chromatin remodelling complex that has been implicated in the aetiology of intellectual disability (ID). Among the dominant ID genes, the SWI/SNF complex is the most highly enriched protein complex. However, its role in the nervous system is not yet understood. I systematically investigated the role of this complex in the development of the Drosophila mushroom body (MB), a complex brain structure required for learning and memory. Gross MB morphology was assessed using confocal microscopy to identify morphological defects following RNAi-mediated knockdown of the 15 individual SWI/SNF genes in the MB. Knockdown of …

Arts & Sciences Electronic Theses and Dissertations
The seemingly limitless capacities of mammals to sense, respond, and manipulate their environments stems from their structurally and functionally diverse nervous systems. Establishing these complex behaviors requires the integration of many biological phenomena including, morphogenetic gradients, cell-cell signaling, transcriptional networks, cell migration and epigenetic gene regulation. As mammalian development progresses, these pathways coordinate the production of highly specialized neuronal and glial cells, that connect and communicate with another in an even more complex manner. While evolution has shaped a multitude of pathways to produce numerous favorable traits, it has also created an intricate system vulnerable to disease. The loss of …
Epigenetic Editing To Validate Findings From Methylome-Wide Association Studies Of Neuropsychiatric Disorders, Robin F. Chan
Epigenetic Editing To Validate Findings From Methylome-Wide Association Studies Of Neuropsychiatric Disorders, Robin F. Chan
Theses and Dissertations
DNA methylation is necessary for learning, memory consolidation and has been implicated in a number of neuropsychiatric disorders. Obtaining high quality and comprehensive data for the three common forms of methylation in brain is challenging for methylome-wide association studies (MWAS). To address this we optimized a panel of enrichment methods for screening the brain methylome. Results show that these enrichment techniques approach the coverage and fidelity of the current gold standard bisulfite based techniques. Our MBD-based method can also be used with low amounts of genomic material from limited human biomaterials. Psychiatric disorders have high prevalence and are often chronic …
