<p>Parkinson’s disease (PD) is a complex neurodegenerative movement disorder involving protein misfolding, mitochondrial dysfunction, and oxidative stress. The current dissertation, motivated by a lack of valid biomarkers and sustainable therapies, examined the potential application of a novel target for therapeutics and diagnostics of PD — the multifunctional, heat-shock like protein Catecholamine-Regulated Protein 40 (CRP40). The goal of this program of research was to elucidate further the implications of CRP40 in PD using a variety of molecular biology, bioinformatics, and clinical approaches through integrative collaborations with academia, government, and industry partners to translate scientific findings into real world solutions. Chapters 2 and 3 explored the potential therapeutic use and structure-function relationships of CRP40 through elucidating the smallest functional piece of this protein that was six times smaller, and validating a negative control for these experiments (Heat-Shock Protein 47). These initiatives could eventually lead to a small drug that could cross the blood-brain barrier and be targeted to the specific brain regions affected in PD. Chapter 4 examined the potential mechanisms of CRP40, and suggested that this protein may protect neurons from oxidative stress, maintain energy levels, and mitochondrial homeostasis, with important future implications for a variety of disorders. Finally, Chapter 5 presented compelling evidence for the potential use of CRP40 as a valid biomarker for early detection of PD and monitoring of disease progression. Overall, findings suggest that CRP40 may be a critical target for future breakthroughs in the diagnosis and treatment of PD.</p> / Doctor of Science (PhD)
