Hutchinson-Gilford Progeria Syndrome Vascular Pathology: A Focused Review, Danielle M. Eschedor
Senior Honors Theses
Hutchinson-Gilford Progeria is an accelerated aging disorder caused by a de novo point mutation in the LMNA gene which codes for an intermediate filament of the nuclear lamina called lamin A. The point mutation at c.1824C>T causes a 50-amino-acid deletion that removes the binding site for Zmpste24, a metalloprotease responsible for defarnesylating prelamin A and producing mature lamin A. Without the ability to be defarnesylated, the mutated protein, called progerin, is more lipophilic and has a myriad of cytotoxic effects. As cardiovascular disease is the most common cause of death in HGPS patients, it is important for both healthcare …
Analysis Of Differential Mrna And Mirna Expression In An Alzheimer’S Disease Mouse Model, Amanda Hazy, Matthew Dalton
Analysis Of Differential Mrna And Mirna Expression In An Alzheimer’S Disease Mouse Model, Amanda Hazy, Matthew Dalton

Research has shown that changes in gene expression play a critical role in the development of Alzheimer’s Disease (AD). Our project will evaluate genome-wide RNA expression patterns from brain and blood in an AD mouse model. This analysis will provide insight regarding the mechanisms of AD pathology as well as determine a possible diagnostic tool utilizing RNA expression patterns found in the blood as biomarkers for AD.

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. …
