Zn(Ii), Cu(Ii), Sn(Ii), And Ni(Ii) And Other Metal Cations Do Not Prevent The Aggregation Of Hiapp, Charles Hoying
Honors Thesis
The Zn(II) metal ion has been shown to interact with Islet Amyloid Polypeptide (IAPP), a protein implicated in the progression of Type II Diabetes Mellitus, in such a way as to prevent the protein from aggregating into toxic fibers. We set out to find whether other metal ions might similarly prevent IAPP aggregation. Using Thioflavin T (ThT) spectroscopic assays, which measure fluorescence of ThT upon binding to aggregated IAPP, we observed a decrease in aggregation when incubated with Zn(II), Cu(II), Ni(II), and Sn(II). Atomic Force Microscopy (AFM), which can visualize fibril formation, revealed that the metals were not inhibiting IAPP …

Legacy Theses & Dissertations (2009 - 2024)
We developed a new technology to study protein-protein interaction in mammalian cells. This technology is based high resolution of Nucleic Magnetic Resonance (NMR) spectroscopy. Using this technology we studied interaction between the receptor for advanced glycation endproducts (RAGE). RAGE- is a multiligand receptor of immunoglobulin receptor family that is activated by a multitude of ligands. Activation of RAGE results in signal transduction that leads to the inflammatory response implicated in the complications of Diabetes. RAGE is an emergent drug target that has been explored for the variety of pathologist including cancers, neurological disorders, inflammatory disease, and diabetes. and Intracellular effector …
