Characterization of the Plasmids of the Pathogenic Plant Bacterium Erwinia amylovora in Washington and Oregon

Creator:: Carey, Alyssa B.
Abstract:: Erwinia amylovora is a plant pathogenic bacterium that causes the destructive disease fire blight of apple and pear. We examined the plasmid content of a collection of 305 isolates of E. amylovora from Washington and Oregon with PCR assays and RFLP. Nearly all isolates of E. amylovora carried plasmid pEA29,...

Stand Structure of Old Growth Dry Mixed Conifer Forests in the Deschutes and Ochoco National Forests

Creator:: Merschel, Andrew G.
Abstract:: Old-growth dry-mixed conifer forests are valued as habitats for late seral forest species, for the ecosystem services and landscape diversity they provide, and for their aesthetic appeal. The structure of these forests has been heavily altered by historic logging of overstory ponderosa pine and Douglas-fir. Additionally, changes in fire regime...

DNA Mismatch Repair-Dependent Suppression of Genotoxicity of Benzo[a]pyrene Diol Epoxide

Creator:: Kernan, Casey P.
Abstract:: DNA mismatch repair (MMR) plays an important role in preserving genomic stability and reducing cancer risk. Environmental exposures to polycyclic aromatic hydrocarbons (PAHs) are believed to contribute significantly to carcinogenesis. PAHs are found in food, air, water and soil and upon bioactivation can form diol epoxides which are electrophilic in...

Investigating the Role of the MutLα Endonuclease

Creator:: Mankaney, Gautam Naresh
Abstract:: Lynch individuals have a predisposition to developing colorectal and other cancers due to inherited defects in their mismatch repair (MMR) system. Although mutations in MMR have been directly implicated in Lynch Syndrome, the precise mechanism(s) of MMR functions have yet to be elucidated. One essential complex, MutL (a dimer of...

A Novel Approach to the Biochemical Analysis of Variants in the Essential DNA Mismatch Repair Protein MLH1

Creator:: Nguyen, Andrew
Abstract:: Genomic integrity is crucial for the viability and function of a cell. One key pathway that acts to maintain genomic integrity is DNA mismatch repair (MMR). MMR acts to correct base pair mismatches hat have escaped proofreading during DNA replication. The process of MMR is dependent on the protein heterodimer...

Pathogenic Mechanisms of Cancer Causing hMLH1 Mutations

Creator:: O'Donnell, Edmond Francis
Abstract:: DNA mismatch repair (MMR) is an evolutionary conserved process that functions to maintain genomic integrity through the correction of mismatches that have escaped proofreading. Mutations in the MMR gene Mlh1 are associated with approximately 50% of all cases of Lynch syndrome, a hereditary predisposition to colorectal cancer, through varying and...

Mismatch Repair-Dependent Cellular Responses to Polycyclic Aromatic Hydrocarbons: An Investigation of Research Methods and Materials

Creator:: Wickramanayake, Anneka
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic chemical compounds found in the environment, largely as a result of partial combustion of organic compounds. PAHs are present in the atmosphere in populated cities worldwide. Because of the health risks they create, PAHs are a global health concern. PAHs are introduced into the...

Creating Test Baking Methods Specifically for Whole-Wheat Sourdough Breads, In the Context of Local Grain Economies

Creator:: Jansen, Victoria E.
Abstract:: Recently local grains have become an area of economic growth. Local grain products, including whole-wheat and sourdough products, are increasingly in demand for their health benefits, unique flavor profiles, and association with local food movements. These local grain economies are beginning to boom, but they lack the technical aid that...

Probing Circadian Clock-Steroid Receptor Interactions in GnRH Neurons

Creator:: Grimwood, Victoria J.
Abstract:: Endogenous circadian clock regulation is essential to normal rhythmicity, particularly the timing of hormone release in the brain. In the context of mammalian reproduction, a surge of a specific hormone, gonadotrophin-releasing hormone (GnRH), initiates a surge of luteinizing hormone (LH) from the pituitary gland, which is required for ovulation in...

Partial Characterization of the Danio rerio and Xenopus tropicalis MT-‐Ox Enzyme Involved in Gadusol Biosynthesis

Creator:: Roemelt, Taylor
Abstract:: Ultraviolet (UV)-protective compounds, such as mycosporine-like amino acids (MAA) are critical for the survival of marine organisms exposed to high-solar radiation. A chemically similar compound, gadusol, was discovered in eggs of the atlantic cod in 1980, and was originally thought to be derived from MAAs that had been ingested. However,...
