Polyglutamine (polyQ) diseases are inherited fatal neurodegenerative disorders caused by expansion of trinucleotide cytosine-adenine-guanine (CAG) repeats, encoding abnormally long glutamine tracts in respective disease proteins. Currently, there are nine polyQ diseases- including Huntington’s disease and a number of Spinocerebellar ataxias. Interestingly, expanded polyQ proteins are prone to aggregate, and this aggregation may underlie neurodegeneration. In this study, we investigate the expression and localization of FAM171B (a novel polyQ protein) in the brain. Western blotting reveals that FAM171B protein is indeed expressed in the developing and adult mouse brain. Furthermore, immunohistochemical analyses suggests widespread localization of FAM171B to many brain regions …
Effects Of Arginine On The Kinetics Of Bovine Insulin Aggregation Studied By Dynamic Light Scattering, Michael M. Varughese
Effects Of Arginine On The Kinetics Of Bovine Insulin Aggregation Studied By Dynamic Light Scattering, Michael M. Varughese
Honors Theses
In the fields of protein science and medicine, understanding the kinetics of protein aggregation are significant in the research and treatment of certain amyloid diseases such as Alzheimer’s. Previous studies have suggested that arginine can increase the solubility of certain proteins, suppress protein aggregation, and assist in the refolding of aggregated proteins; however, the molecular mechanisms by which arginine can influence protein aggregation are still unclear. Bovine insulin was employed as a model system for further understanding the effects of arginine on protein aggregation. Using Dynamic Light Scattering (DLS), we studied the concentration-dependent and temperature-dependent suppression of aggregation in insulin …
