Identification And Molecular Analysis Of Dna In Exosomes, Jena Tavormina
Dissertations & Theses (Open Access)
Exosomes are heterogeneous nanoparticles 50-150nm in diameter. Exosomes contain many functional cargo components, such as protein, DNA, and RNA. While protein and RNA exosome content has been extensively studied, very little work has been done to characterize exosomal DNA. Here, we demonstrate that exosomal DNA is heterogeneous and its packaging into exosomes is dependent on the cell of origin. Furthermore, through a rigorous assessment of various isolation methods, we identify Size Exclusion Chromatography (SEC) as the best method for the isolation of exosomal DNA for downstream applications. Additionally, we evaluate the methylation status of exosomal DNA and demonstrate that exosomal …

Improving The Genetic Diagnosis Of Familial Hypercholesterolemia, Michael Iacocca
Electronic Thesis and Dissertation Repository
Familial hypercholesterolemia (FH) is a genetic disorder of severely elevated low-density lipoprotein (LDL) cholesterol that is widely underdiagnosed and undertreated. To improve the identification of FH and initiate timely and appropriate treatment strategies, genetic testing is becoming increasingly offered worldwide as a central part of diagnosis. I describe three main ways providing a genetic diagnosis in FH can be improved. First, next-generation sequencing (NGS)-based approaches can be used to reliably identify large-scale variant types known as copy number variations (CNVs) in the LDL receptor gene (LDLR); second, NGS methodology can be further applied to extend CNV screening to …
