Dna Methylation And The Response To Infection In Introduced House Sparrows, Melanie Gibson
Dna Methylation And The Response To Infection In Introduced House Sparrows, Melanie Gibson
Electronic Theses and Dissertations
Epigenetics is the study of molecular modification of a genome without changing its base pairs. The most studied type of epigenetic mechanism is DNA methylation, which is capable of turning a gene “on” or “off.” Epigenetic potential is the capacity to which an individual can have methylation on its genome. The more CpGs available, the greater the epigenetic potential. In invasive species, genetic variation has been observed to be paradoxical: not much of it exists on a genomic level, but epigenetically, phenotypic variation can occur. The focus on shift in gene expression in this study is on Toll-Like Receptor 4 …
Identifying The Cell Composition And Clonal Diversity Of Supratentorial Ependymoma Using Single Cell Rna-Sequencing, James He
Honors Scholar Theses
Ependymoma is a primary solid tumor of the central nervous system. Supratentorial ependymoma (ST-EPN), a subtype of ependymomas, is driven by an oncogenic fusion between the ZFTA and RELA genes in 70% of cases. We introduced this fusion into neural progenitor cells of mice embryos via in utero electroporation of a non-viral binary piggyBac transposon system containing ZFTA-RELA. From preliminary data in the LoTurco lab, inducing the expression of ZFTA-RELA into different neural progenitor cells produces tumors of varying lethality and cellular composition. To define the cellular composition and subclonal diversity of ST-EPN tumors, we used single cell RNA-sequencing …
Metallothionein Gene Dose And The Immune Response, Meaghan Roy-O-Reilly
Metallothionein Gene Dose And The Immune Response, Meaghan Roy-O-Reilly
Honors Scholar Theses
Metallothionein (MT) is a small, cysteine-rich protein with significant immunomodulatory activity. It has been shown to play a critical role in important cellular mechanisms including heavy metal detoxification, essential metal management and the inflammatory response. MT production can be induced by a number of cellular stressors and acts to lessen the harmful effects of oxidizing agents and heavy metal exposure. Previous studies have shown that the dose of the metallothionein gene present in an individual may have significant effects on the adaptive immune response, yet the mechanism behind this phenomenon remains unknown. We hypothesize that the gene dose of metallothionein …
