Regulation Of Ty1 Retrovirus-Like Transposon Rna Localization And Translation, Ryan Joseph Palumbo
Regulation Of Ty1 Retrovirus-Like Transposon Rna Localization And Translation, Ryan Joseph Palumbo
Legacy Theses & Dissertations (2009 - 2024)
Replication of the Ty1 retrovirus-like transposon of the yeast Saccharomyces cerevisiae is stringently regulated to reduce the frequency of deleterious retrotransposition events. However, under stress conditions, Ty1 retrotransposition can lead to adaptive genomic alterations. To characterize host regulation of Ty1 retrotransposition, I analyzed ribosome profiling data and showed that Ty1 RNA is efficiently translated. Moreover, the ribosome biogenesis factors BUD21, DBP7, HCR1, LOC1, MRT4, and PUF6 are required for optimal expression of the Ty1 protein Gag.
Regulation Of Immune Response Genes By Vitamin D In Mammary Epithelial Cells With An Emphasis On Cd14, Katrina Marie Simmons
Regulation Of Immune Response Genes By Vitamin D In Mammary Epithelial Cells With An Emphasis On Cd14, Katrina Marie Simmons
Legacy Theses & Dissertations (2009 - 2024)
Vitamin D is primarily known for its role in bone health, however recently vitamin D has been identified as a potent immunomodulator. Most research studying the effects of vitamin D on immune properties have focused on immune cells. Few have evaluated how vitamin D affects the immune functions of barrier epithelial cells, such as human mammary epithelial (HME) cells, that are exposed to pathogens both locally and systemically. The goals of the studies described in this thesis were to comprehensively and mechanistically evaluate the immune effects of vitamin D metabolites, 1α,25-dihydroxyvitamin D (1,25D) and 25-hydroxyvitamin D (25D), on HME cells. …
Genetic Diversity And Population Structure Of Brook Trout (Salvelinus Fontinalis) In A Remote Adirondack Watershed, Spencer A. Bruce
Genetic Diversity And Population Structure Of Brook Trout (Salvelinus Fontinalis) In A Remote Adirondack Watershed, Spencer A. Bruce
Legacy Theses & Dissertations (2009 - 2024)
In conservation genetics, the importance of understanding how historical and contemporary processes have contributed to geographic patterns of genetic structure is key to preserving diversity. In New York State there are currently eleven remaining known populations of native brook trout (Salvelnius fontinalis) that inhabit the watersheds for which they are named. These populations are known as "heritage strains", and are currently managed under regulations set by the New York State Department of Environmental Conservation.
Molecular Actions Of The Vitamin D Receptor In Breast Cancer, Erika Laporta
Molecular Actions Of The Vitamin D Receptor In Breast Cancer, Erika Laporta
Legacy Theses & Dissertations (2009 - 2024)
1,25-Dihydroxyvitamin D (1,25D) exerts anti-cancer actions through the vitamin D receptor (VDR) but the specific targets that mediate these effects remain to be defined. In these studies, growth and genomic responses to 1,25D were evaluated in a cellular model system derived from mammary tumors generated in VDR knockout (KO) and wildtype (WT) mice. WT145 cells (derived from WT tumors) expressed VDR and were growth inhibited by 1,25D, whereas KO240 cells (derived from VDRKO tumors) lacked VDR and were not growth inhibited by 1,25D. KO240 cell clones stably expressing VDR (KOhVDR cells) were sensitized to 1,25D mediated growth arrest. Genomic profiling …
