Transcription Factor-Mediated Epigenetic Regulation In The Healthy Brain And Neurological Disease, Alexander J. Cammack May 2020

Transcription Factor-Mediated Epigenetic Regulation In The Healthy Brain And Neurological Disease, Alexander J. Cammack

Arts & Sciences Electronic Theses and Dissertations

Proper cellular development and function is a complex process established by elaborate gene expression networks. These networks are regulated by epigenetic processes, which alter chromatin states and coordinate the binding of transcription factors (TFs) to regulatory elements (REs), such as enhancers, across the genome to facilitate gene expression. It follows then that a major experimental effort is to profile and understand the binding patterns of TFs to REs in various cellular types and contexts. Critically however, current TF profiling techniques are limited in their abilities to profile TF occupancy in targeted cellular populations and temporal windows, hindering investigations into epigenetic …

The microtubule associated protein tau (MAPT, commonly referred to as tau) is an intrinsically disordered, highly soluble protein predominantly expressed in axons where it binds and stabilizes microtubules. Under normal physiological conditions, soluble monomeric tau is released in the extracellular space in the interstitial fluid (ISF) by neurons. Additionally it undergoes reversible phosphorylation and other extensive modifications inside the cell under the action of a host of enzymes. However in the disease process tau loses this solubility, detaches from microtubules and ultimately migrates to the somatodendritic compartment of the neuron, where it ultimately forms insoluble fibrillar aggregates known as tau …
