Terrestrial Salinization Impacts On Growth And Behavior Of A Common Detritivore Armadillidium Vulgare (Isopoda), Danielle Harmoney Orcutt Aug 2024

Terrestrial Salinization Impacts On Growth And Behavior Of A Common Detritivore Armadillidium Vulgare (Isopoda), Danielle Harmoney Orcutt

Master's Theses

Climate change and human activities are changing the nutritional landscape by increasing the availability of some essential elements and decreasing others. Sodium (Na) is an essential element in heterotrophs, which is required for water regulation, nerve function, and muscle function. Heterotrophs can acquire Na through diet and environment, often experiencing limited availability of Na due to plants concentrating Na 10-100 times less than heterotrophs need. The Sodium Subsidy-Stress (SSS) hypothesis posits that organismal performance follows a hump-shaped curve of a physiological response, where Na acts as a subsidy, increasing organismal performance such as growth until an optimal threshold is reached, …


Akt Disruption Leads To Non-Canonical Apical Constriction In Drosophila Embryos, Vincent Brown Aug 2024

Akt Disruption Leads To Non-Canonical Apical Constriction In Drosophila Embryos, Vincent Brown

Electronic Theses and Dissertations

The Akt/mTOR pathway (Akt pathway) has largely been examined in terms of its role as the primary nutrient sensing pathway due to its ability to recognize nutrient availability within a cell, particularly amino acids and glucose. Among its nutrient sensing characteristics, this pathway also contributes to a large variety of other cell functions such as cell growth, proliferation, protein synthesis, and cell survival via anti-apoptotic signaling. Although many aspects of this pathway have been carefully studied, the extent to which it regulates embryonic development remains unclear. Here, I examine Akt function in the early Drosophila embryo and demonstrate that Akt …

Developing Tools To Study The Effect Of The Mechanical Environment On Plant Cell Growth And Morphogenesis, Ryan Calcutt

Arts & Sciences Graduate Student Theses and Dissertations

Mechanical forces are omnipresent in life on Earth and responses to force can be found across all three domains of life. The colonization of land by plants approximately 500 million years ago, an event that shaped life on Earth as we know it, involved adaptation from a relatively homogeneous fluid mechanical environment to a highly heterogeneous and mechanically diverse terrestrial environment. Evolution of multicellularity would present new mechanical challenges for land plants, not only from externally generated forces, but also from mechanical linkage to neighboring cells through the cell wall. Coordination of cell growth and an indeterminate body plan requires …

Gnotobiotic Mouse Models For Characterizing The Role Of The Microbiota On Undernutrition And Early Postnatal Brain Development, Alexandra Elizabeth Byrne

Arts & Sciences Graduate Student Theses and Dissertations

Undernutrition is a serious global health challenge; it accounts for nearly half of all mortality for children under the age of 5. Worse, undernutrition is compounded by intergenerational inheritance and can be transmitted from mother to offspring. The burden of undernutrition is unequally distributed around the world, with South Asia and Sub-Saharan Africa accounting for almost 60% of the global childhood stunting. Undernutrition is detrimental to many aspects of development, including long-term deficits in neurodevelopment, and current interventions rarely ameliorate long-term cognitive and motor deficits. Therefore, other causes of undernutrition need to be elucidated in order to treat this epidemic …

Molecular Mechanisms Behind Methionine-Derived Glucosinolate Diversity In Brassica Plants, Vivian Kitainda Aug 2024

Molecular Mechanisms Behind Methionine-Derived Glucosinolate Diversity In Brassica Plants, Vivian Kitainda

Arts & Sciences Graduate Student Theses and Dissertations

In Brassica plants, glucosinolates are a diverse class of natural products that serve as plant defense molecules. Their structural diversity comes from the use of amino acids as precursors and elongation of side chains by up to nine carbons, as well as further chemical modifications. Aliphatic methionine-derived glucosinolates are the most abundant form of these compounds. Although both elongation and chemical modification of amino acid sidechains are important for methionine-glucosinolate diversity, its elongation process has not been well described. The chain elongation enzyme methylthioalkylmalate synthase (MAMS) functions as the glucosinolate pathway gatekeeper through its substrate specificity. The x-ray crystal structure …

Cancer cells exhibit phenotypical plasticity and epigenetic reprogramming that allows them to evade lineage-dependent targeted treatments by adopting lineage plasticity. The underlying mechanisms by which cancer cells exploit the epigenetic regulatory machinery to acquire lineage plasticity and therapy resistance remain poorly understood. We identified zinc finger protein 397 (ZNF397) as a bona fide coactivator of the androgen receptor (AR), essential for the transcriptional program governing AR-driven luminal lineage. ZNF397 deficiency facilitates the transition of cancer cell from an AR-driven luminal lineage to a ten-eleven translocation 2 (TET2)-driven lineage plastic state, ultimately promoting resistance to therapies inhibiting AR signaling. Intriguingly, our …
