Graduate School of Biomedical Sciences Theses and Dissertations
Developmental timing is a key aspect of tissue and organ formation in which distinct cell types are generated through a series of steps from common progenitors. These progenitors undergo specific changes in gene expression that signifies both a distinct progenitor type and developmental time point that thereby specifies a particular cell fate at that stage of development. The nervous system is an important setting for understanding developmental timing because different cell types are produced in a certain order and the switch from stem cells to progenitors requires precise timing and regulation. Notable examples of such regulatory molecules include the RNA-binding …

Alzheimer’s disease (AD) is characterized by neurofibrillary tangles and extracellular amyloid-β plaques (Aβ). Despite ongoing research, some ambiguity remains surrounding the role of Aβ in the pathogenesis of this neurodegenerative disease. While several studies have focused on the mutations associated with AD, our understanding of the epigenetic contributions to the disease remains less clear. To that end, we determined the changes in DNA methylation in differentiated human neurons with and without Aβ treatment. We isolated the DNA from neurons treated with Aβ or vehicle, and digested the two samples with either a methylation-sensitive (HpaII) or a methylation-insensitive (MspI) restriction endonuclease. …

Studies have shown that there is a strong correlation between aging and neurodegenerative diseases. Aging is considered the number one risk factor to develop neuropathologies such as memory loss, senile dementia, Alzheimer's disease (AD), and Parkinson's disease. Neurodegenerative diseases tend to start during adulthood, and aggravate over time, making them difficult to prevent and to treat. In the Unites States, demographic studies by U.S. Bureau of the Census have determined that our aging population of >65 years is expected to increase from the present 35 million to 78 million in 2030. This would result, not only to an increase of …
