Some potential mechanisms for finely-tuned regulation of phospholipase C-β isozymes : studies of dimerization and phosphatidylinositol 3,4,5-trisphosphate activation

Creator:: Zhang, Yong
Abstract:: Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled signaling pathways. Prior research suggested that some isoforms of PLC-β may exist and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation assays of differentially-tagged PLC-β constructs and sizeexclusion chromatography of native PLC-β support homodimerization...

Modifying the Hormone Strategy for Superovulating Donor Cows to Reduce Drug Costs without Decreasing the Number of High Quality Transferable Embryos Recovered

Creator:: Gomes, Maria K.
Abstract:: Two research projects comprise this thesis. The first project investigated modifying the hormone dosing strategy traditionally used in superovulating donor cows for an embryo collection to decrease drug costs without decreasing the number of high quality, transferable embryos recovered. The objective of this project was to evaluate the number and...

Molecular Analysis of Tomato Seed Germination and Tomato Production in Almería, Spain

Creator:: Nguyen, Theresa T.
Abstract:: Tomato is considered to be one of the most important vegetables for its value as a source of nutrients and antioxidants, and as a model crop for biological research, including seed biology. In this thesis, tissue-specific gene expression and its regulation in tomato seeds were analyzed to understand the mechanisms...

Possible Autocrine/Paracrine Action of Progesterone in the Ovine Corpus Luteum

Creator:: Smallman, Mary A.
Abstract:: The objective of the present research was to determine, by use of the progesterone receptor antagonist RU-486, whether progesterone by autocrine/paracrine action suppresses phosphatidylinositol hydrolysis, and thus, the production of prostaglandin F2a during the midluteal phase of the estrous cycle in ewes. Two experiments were performed. Experiment 1 consisted of...

Crossing Boundaries during Stress Responses: Antigen Presentation by Adaptive and Innate MHC Class I Molecules

Creator:: Nagamine, Brandy S.
Abstract:: The immune system is a complex network of cellular processes working in harmony to guard us against pathogenic attack. Of utmost importance is the ability of the immune system to discriminate between “self” and “non-self” and diseased versus healthy. Recognition of antigens complexed to major histocompatibility complex (MHC) molecules is...

Investigating the ecological role of cell signaling in free-living marine heterotrophic protists

Creator:: Hartz, Aaron J.
Abstract:: Phagotrophic protists are major consumers of microbial biomass in aquatic ecosystems. However, biochemical mechanisms underlying prey recognition and phagocytosis by protists are not well understood. We investigated the potential roles of cell signaling mechanisms in chemosensory response to prey, and in capture of prey cells, by a marine ciliate (Uronema...

An emerging role for the exocyst : plant morphogenesis

Creator:: Cole, Rex A.
Abstract:: Plants develop a vast array of cell shapes and sizes by selectively modifying their surrounding cell walls to expand in some regions and not in others. This process of morphogenesis requires the delivery of secretory vesicles to specific locations at the cell periphery, where exocytosis adds new membrane and proteins...

Towards Resolving Functional and Evolutionary Mysteries of the Large and Heterozygous Genome of Hop (Humulus lupulus) and the Cannabaceae Family Using Genomic Data Science

Creator:: Padgitt-Cobb, Lillian K.
Abstract:: Hop (Humulus lupulus L. var. lupulus) is a diploid, dioecious plant with an extensive history of cultivation and use in brewing, as a textile, and for its therapeutic properties. Hop is prized for its ability to produce a variety of aromatic and flavor compounds, as well as compounds with anti-microbial...

Always talk to strangers

Creator:: Buck, C. Nathan
Abstract:: Always Talk to Strangers contains the first seven chapters to a novel. The novel focuses on the friendship between Amanda and Maria, two fourteen-year-old girls who are experiencing their last summer before high school in Madison, Wisconsin. Their friendship is a complicated one: Maria was kidnapped four years ago, the...

Mixed ethnic identity in the United States

Creator:: Lonergan, Courtney C.
Abstract:: In this paper I focus on the process of formulating an ethnic identity in the United States for individuals of mixed-ethnicity. My main question explores the complexities an individual with parents of separate and distinct ethnic heritages faces when constructing an ethnic identity in our society. American society is reaching...
