The Cellular Nucleic Acid Binding Protein Regulates The Alzheimer’S Disease Β-Secretase Protein Bace1, Christopher J. Holler

Theses and Dissertations--Molecular and Cellular Biochemistry

Alzheimer’s disease (AD) is the most common neurodegenerative disease affecting the elderly population and is believed to be caused by the overproduction and accumulation of the toxic amyloid beta (Aβ) peptide in the brain. Aβ is produced by two separate enzymatic cleavage events of the larger membrane bound amyloid precursor protein, APP. The first, and rate-limiting, cleavage event is made by beta-secretase, or BACE1, and is thus an attractive therapeutic target. Our lab, as well as many others, has shown that BACE1 protein and activity are increased in late-stage sporadic AD. We have extended these findings to show that BACE1 …

Investigating The Role Of Prion Protein Polymorphisms On Prion Pathogenesis, Eri Saijo

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Transmissible spongiform encephalopathies (TSEs), also known as prion diseases, are lethal and infectious neurodegenerative diseases of humans and animals. The misfolding of the normal, or cellular isoform of the prion protein (PrP^C) into the abnormal disease-associated isoform of PrP (PrP^Sc) could change the properties of PrP, consequently, PrP^Sc has lethal infectivity to transmit diseases. The proteinaceous infectious particle consisting mainly of PrP^Sc is called prion. Transmissibility of prions is strongly influenced by multiple factors including PrP polymorphisms, species barriers (PrP sequence specificity) and prion strains (conformational specificity) by unknown mechanisms. Even though the ability …

A Proposal To Test The Effects Of Factor Ecat1 On Pluripotency, From Reprogramming To Differentiation Of Human Somatic Cells, Vritti R. Goel

CMC Senior Theses

The field of stem cell research has been growing more because of the interest in using stem cells to cure diseases and heal injuries. Human embryonic stem cells, because of the controversy surrounding them—and subsequently the difficulties in acquiring samples of the existing aging cell lines—can only be used in limited capacities. While the development of induced pluripotent stem cells in the last decade has allowed the field to progress closer to medical treatments, the low efficiency of reprogramming a somatic cell to a pluripotent state, and the vast molecular and genomic differences between human embryonic stem cells and human …
