Current and Future Land Use around a Nationwide Protected Area Network

Creator:: Hamilton, Christopher M., Martinuzzi, Sebastian, Plantinga, Andrew J., Radeloff, Volker C., Lewis, David J., Thogmartin, Wayne E., Heglund, Patricia J., and Pidgeon, Anna M.
Abstract:: Land-use change around protected areas can reduce their effective size and limit their ability to conserve biodiversity because land-use change alters ecological processes and the ability of organisms to move freely among protected areas. The goal of our analysis was to inform conservation planning efforts for a nationwide network of...

Effects of Sulforaphane and 3,3'-Diindolylmethane on Genome-Wide Promoter Methylation in Normal Prostate Epithelial Cells and Prostate Cancer Cells

Creator:: Wong, Carmen P., Hsu, Anna, Buchanan, Alex, Palomera-Sanchez, Zoraya, Beaver, Laura M., Houseman, E. Andres, Williams, David E., Dashwood, Roderick H., and Ho, Emily
Abstract:: Epigenetic changes, including aberrant DNA methylation, result in altered gene expression and play an important role in carcinogenesis. Phytochemicals such as sulforaphane (SFN) and 3,3′-diindolylmethane (DIM) are promising chemopreventive agents for the treatment of prostate cancer. Both have been shown to induce re-expression of genes, including tumor suppressor genes silenced...

What the Inbred Scandinavian Wolf Population Tells Us about the Nature of Conservation

Creator:: Räikkönen, Jannikke, Vucetich, John A., Vucetich, Leah M., Peterson, Rolf O., and Nelson, Michael P.
Abstract:: The genetic aspects of population health are critical, but frequently difficult to assess. Of concern has been the genetic constitution of Scandinavian wolves (Canis lupus), which represent an important case in conservation. We examined the incidence of different congenital anomalies for 171 Scandinavian wolves, including the immigrant founder female, born...

Circadian Regulation of Glutathione Levels and Biosynthesis in Drosophila melanogaster

Creator:: Beaver, Laura M., Klichko, Vladimir I., Chow, Eileen S., Kotwica-Rolinska, Joanna, Williamson, Marisa, Orr, William C., Radyuk, Svetlana N., and Giebultowicz, Jadwiga M.
Abstract:: Circadian clocks generate daily rhythms in neuronal, physiological, and metabolic functions. Previous studies in mammals reported daily fluctuations in levels of the major endogenous antioxidant, glutathione (GSH), but the molecular mechanisms that govern such fluctuations remained unknown. To address this question, we used the model species Drosophila, which has a...

Phytophthora Have Distinct Endogenous Small RNA Populations That Include Short Interfering and microRNAs

Creator:: Fahlgren, Noah, Bollmann, Stephanie R., Kasschau, Kristin D., Cuperus, Josh T., Press, Caroline M., Sullivan, Christopher M., Chapman, Elisabeth J., Hoyer, J. Steen, Gilbert, Kerrigan B., Grunwald, Niklaus J., and Carrington, James C.
Abstract:: In eukaryotes, RNA silencing pathways utilize 20-30-nucleotide small RNAs to regulate gene expression, specify and maintain chromatin structure, and repress viruses and mobile genetic elements. RNA silencing was likely present in the common ancestor of modern eukaryotes, but most research has focused on plant and animal RNA silencing systems. Phytophthora...

Sources and Levels of Ambient Ocean Sound near the Antarctic Peninsula

Creator:: Dziak, Robert P., Bohnenstiehl, DelWayne R., Stafford, Kathleen M., Matsumoto, Haruyoshi, Park, Minkyu, Lee, Won Sang, Fowler, Matt J., Lau, Tai-Kwan, Haxel, Joseph H., and Mellinger, David K.
Abstract:: Arrays of hydrophones were deployed within the Bransfield Strait and Scotia Sea (Antarctic Peninsula region) from 2005 to 2009 to record ambient ocean sound at frequencies of up to 125 and 500 Hz. Icequakes, which are broadband, short duration signals derived from fracturing of large free-floating icebergs, are a prominent...

Geomorphic and Ecological Disturbance and Recovery from Two Small Dams and Their Removal

Creator:: Tullos, Desirée D., Finn, Debra S., and Walter, Cara
Abstract:: Dams are known to impact river channels and ecosystems, both during their lifetime and in their decommissioning. In this study, we applied a before-after-control-impact design associated with two small dam removals to investigate abiotic and biotic recovery trajectories from both the elimination of the press disturbance associated with the presence...

Frequent Alteration of the Tumor Suppressor Gene APC in Sporadic Canine Colorectal Tumors

Creator:: Youmans, Lydia, Taylor, Cynthia, Shin, Edwin, Harrell, Adrienne, Ellis, Angela E., Seguin, Bernard, Ji, Xinglai, and Zhao, Shaying
Abstract:: Sporadic canine colorectal cancers (CRCs) should make excellent models for studying the corresponding human cancers. To molecularly characterize canine CRC, we investigated exonic sequence mutations of adenomatous polyposis coli (APC), the best known tumor suppressor gene of human CRC, in 23 sporadic canine colorectal tumors, including 8 adenomas and 15...

Simulated Evolution of Protein-Protein Interaction Networks with Realistic Topology

Creator:: Peterson, G. Jack, Pressé, Steve, Peterson, Kristin S., and Dill, Ken A.
Abstract:: We model the evolution of eukaryotic protein-protein interaction (PPI) networks. In our model, PPI networks evolve by two known biological mechanisms: (1) Gene duplication, which is followed by rapid diversification of duplicate interactions. (2) Neofunctionalization, in which a mutation leads to a new interaction with some other protein. Since many...

Development of Molecular Markers for Determining Continental Origin of Wood from White Oaks (Quercus L. sect. Quercus)

Creator:: Schroeder, Hilke, Cronn, Richard, Yanbaev, Yulai, Jennings, Tara, Mader, Malte, Degen, Bernd, and Kersten, Birgit
Abstract:: To detect and avoid illegal logging of valuable tree species, identification methods for the origin of timber are necessary. We used next-generation sequencing to identify chloroplast genome regions that differentiate the origin of white oaks from the three continents; Asia, Europe, and North America. By using the chloroplast genome of...
