Gene expression in mammalian cells requires complex nuclear choreography, and there is increasing evidence that spatiotemporal organization of chromatin and nuclear compartments plays an important role in gene expression. In this dissertation, I examined the function of SON, a splicing factor with a known role in nuclear organization, in chromatin-mediated gene expression. SON association with a transcriptionally inactive U2OS 2-6-3 reporter gene array provided a useful model to study SON’s chromatin dynamics. I demonstrated that SON associates with the inactive but not the activated array, and that SON’s RNA binding domains are not necessary for that association. Second, I discovered …
Comparative Genomics Of Human Mesenchymal Stem Cells And Human Mesenchymal Stem Cells Derived Vascular Smooth Muscle Cells, Samia Ismail
Comparative Genomics Of Human Mesenchymal Stem Cells And Human Mesenchymal Stem Cells Derived Vascular Smooth Muscle Cells, Samia Ismail
Biomedical Engineering Undergraduate Honors Theses
As of 2017, vascular diseases contributed to 23.1% of all deaths in America. To address the need for more effective and sustainable treatment options for these ailments, stem cell differentiation and implantation has emerged as a viable alternative to standard bypass and graft insertions. A completely autologous treatment can be achieved by extracting adult stem cells, differentiating them into vascular smooth muscle cells (VSMCs), and then reimplanting these cells at the affected tissue site. This study aims to investigate the efficiency of the VSMC differentiation from human mesenchymal stem cells (hMSCs) by comparing 4 cell lines of untreated hMSCs with …

McKelvey School of Engineering Theses & Dissertations
The discovery of fossil fuels facilitated a new era in human history and allowed many firsts, such as the mass production of goods, the ability to travel and communicate long distances, the formation of population dense cities, and unprecedented improvements in quality of life. Alternative sources of energy and chemicals are needed, however, as hydrocarbon reserves continue to deplete and the effects of burning fossils on the planet become better understood. Lignocellulosic biomass is the most abundant raw material in the world and a viable alternative to petroleum-derived products. The pre-treatment of lignocellulose (e.g., thermocatalytic depolymerization, enzymatic hydrolysis, pyrolysis, etc.) …

To this day, there is no cure for Alzheimer’s disease (AD) and related dementias (ADRD). With the daunting rise at an exponential rate of ADRD burden and related deaths, the necessity to find a new line of attack is vital. Pathological accumulation of microtubule associated protein tau in neurons is a major neuropathological hallmark of Alzheimer’s disease (AD) and related tauopathies. Attempts have been made to promote clearance of pathological tau (p-Tau) from neurons via autophagy. Transcription factor EB (TFEB) has shown to clear p-Tau from neurons via autophagy. However, sustained TFEB activation and autophagy can create burden on cellular …
