Buildup of oxidative stress and mitochondrial dysfunction are well known characteristics of both sporadic and hereditary amyotrophic lateral sclerosis (ALS). While both forms of the disease seem to arise from common cellular dysfunction, the genetic disease is studied to a much greater extent. Engineering novel animal models of the sporadic form of the disease is crucial for development of druggable targets to treat ALS and understand the underlying mechanisms. Interestingly, accumulation of oxidative stress by exacerbated emission of reactive oxygen species (ROS) from presynaptic mitochondria is a hallmark of both hereditary and sporadic ALS. Previous work by our laboratory showed …

Scripps Senior Theses
Parkinson’s disease is a debilitating and often deadly neurodegenerative disease affecting a growing and large population. Its etiology has long remained elusive, and because no other organisms have Parkinsonian-like diseases, it is difficult to study PD using model organisms. Neuromelanin (NM), an insoluble melanin synthesized in the dopaminergic synthesis pathway in DA neurons, has recently been implicated in PD as a major causal factor. At high levels in DA lysosomes, it functions as a proteostatic pathway inhibitor–blocking dopaminergic neurons from breaking down harmful molecules until the lysosomes eventually degenerate as well as triggering autophagy, inflammation, and total neurodegeneration. Recently, neuromelanin …
