  • Protein methylation at sites of blood vessel injury

    Creator:
    Weber, Darin J.
    Abstract:
    Blood vessel injury was found to release intracellular pools of protein D-aspartyl/L-isoaspartyl carboxyl methyltransferase (PIMT) into the extracellular milieu, where it became trapped. Trapped PIMT was able to utilize radiolabeled S-adenosyl-L-methionine (AdoMet) introduced into the circulation to methylate blood vessel proteins containing altered aspartyl residues specifically at the site of...

  • Incorporation of chromatophores into multi-cellular biosensors

    Creator:
    Preston, R. Ryan
    Abstract:
    Methodologies that detect biologically active substances have important potential applications for medical diagnostics, drug discovery, and chemical and biological anti-terrorism efforts. The wide spectrum of potential analytes that induce a physiological response dictates that novel techniques be developed to more rapidly screen and characterize agents that are more economical and...

  • Biologically inspired biosensors from fish chromatophores

    Creator:
    Young, Jun
    Abstract:
    This thesis explores the feasibility of using melanophore-based biosensors from Oreochromis niloticus. Melanophores are one type of pigmented cell of the scales and fins of fish that respond in a motile fashion to a diverse range of stimuli. Fish scales were employed as the first step in determining the utility...

  • The spatial resolution of information in a diffusive cytoplasm

    Creator:
    Sellers, Drew L.
    Abstract:
    Every cell is faced continuously with the task of transducing a vast number of external signals into appropriate intracellular responses. In mammalian cells, membrane bound receptors modulate the production of secondary messenger molecules, such as cyclic AMP (cAMP). Cell signaling through second messengers relies on the diffusion of such second...

  • Automethylation : a response to enzyme aging

    Creator:
    Lindquist, Jonathan A.
    Abstract:
    This is the first study to explore the ability of an enzyme to recognize and repair spontaneous age-dependent damage to its own sequence. Protein (D-aspartyl/L-isoaspartyl) carboxyl methyltransferase (PCM) is known to repair damage that arises from a spontaneous isomerization of aspartyl and asparaginyl residues in other proteins during aging. As...

    Osborn, Andrew
    Abstract:
    Pactamycin, a complex aminocyclitol compound produced by Streptomyces pactum, has significant antibiotic, antitumor, and antiplasmodial activity. However, this natural product has not been developed for clinical use due to its high cytotoxicity. Modulation of its biological properties by chemical synthesis has been difficult due to its complex chemical structure. Therefore,...

  • The stability of pelargonidin-based anthocyanins in natural and model systems

    Creator:
    Garzon, G. Astrid
    Abstract:
    Pelargonidin 3-glucoside (pgd 3-glu), pelargonidin 3-sophoroside (pgd 3-soph), and pelargonidin 3-sophoroside 5-glucoside acylated with cinnamic and malonic acids (acyl-pgd 3-soph 5-glu) were extracted from strawberries (Fragaria anannassa cv, Totem), nasturtium flowers (Tropaeolum majus), and radish peel (Raphanus sativus L. cv, fuego), respectively. Their stability was studied in natural and model...

  • An investigation of the alarm response in anuran amphibian larvae

    Creator:
    Hews, Diana K.
    Abstract:
    The results of my research suggest that tadpoles of the Western toad (Bufo boreas) and the Cascades frog (Rana cascadae) display an alarm response to chemicals from injured conspecific tadpoles. Furthermore, results suggest that the Bufo boreas alarm response can be elicited by a natural predator when it feeds on...

  • Sublethal effects of UV-B radiation on larval amphibians

    Creator:
    Belden, Lisa K.
    Abstract:
    Ultraviolet-B radiation (UV-B) has been suggested as a factor contributing to global amphibian population declines. While ambient UV-B levels damage the eggs and embryos of some amphibian species, few studies have addressed how UV-B affects other life history stages or sublethal responses. My dissertation focuses on (1) investigations of sublethal...
