Tactical reproductive parasitism via larval cannibalism in Peruvian poison frogs
(East Carolina University, 2009-04-23)We report an unusual example of reproductive parasitism in amphibians. Dendrobates variabi- lis, an Amazonian poison frog, oviposits at the surface of the water in small pools in plants and deposits tadpoles within the ... -
Targeting aberrant signaling in the EGFR1/HER2/PI3K/PTEN/Akt/mTORC1/GSK-3 pathway : Novel therapeutic interventions in breast cancer
(East Carolina University, 2015)Breast cancer is attributed to being the second most deadly cancer in American women. Approximately 1 in 8 women will be diagnosed with breast cancer during her lifetime, and prognosis is dependent upon the genetic make-up ... -
Three Generations, One Future: A Systematic Analysis on Nicotine's Effect across generations in C. elegans.
(East Carolina University, 2013)Tobacco smoking is a worldwide epidemic that is responsible for diseases and death rates that surpass those attributed to a combination of other causes (e.g. cancer, HIV, accidents). A major mediator of tobacco-smoke related ... -
TOXICITY OF METAL OXIDE NANOPARTICLES TO CAENORHABDITIS ELEGANS
(East Carolina University, 2012)The increase in manufacturing and use of nanoparticles is expected to elevate levels of exposure to humans and other organisms. Presently, there is little understanding of the potential toxic effects of nanoparticle exposure. ... -
Transcriptional Analysis of the Bacteroides fragilis Starch Utilization Operon, osuA
(East Carolina University, 2011)The opportunistic pathogen Bacteroides fragilis is a symbiotic organism that inhabits the human gastrointestinal tract where it utilizes dietary and host-derived polysaccharides as carbon and energy sources. If abdominal ... -
Tumor Growth Induces Oxidative Clustered DNA Lesions Damage in Distant Mouse Tissue in vivo
(East Carolina University, 2010)Our goal was to ascertain if DNA damage induced by oxidative stress is capable of being exploited as a precancerous or cancer biomarker. The specific DNA damage that we assessed was oxidatively induced non-DSB clustered ... -
USE OF GENETIC TECHNIQUES TO IDENTIFY THE DIET OF COWNOSE RAYS, RHINOPTERA BONASUS, IN NORTH CAROLINA AND VIRGINIA : AN ANALYSIS OF SHELLFISH PREY ITEMS
(East Carolina University, 2013)Cownose rays, Rhinoptera bonasus, are considered voracious predators on mollusks and have been implicated in the consumption of commercially important species of shellfish on the East Coast. Digestive tracts of the 32 ... -
Using student motivation to design groups in a non-majors biology course for team-based collaborative learning : Impacts on knowledge, views, attitudes, and perceptions
(East Carolina University, 2014)The importance of student motivation and its connection to other learning variables (i.e., attitudes, knowledge, persistence, attendance) is well established. Collaborative work at the undergraduate level has been recognized ... -
VALIDATION OF CANDIDATE GENES IN RESPONSE TO VERSICAN MANIPULATION IN DEVELOPING SYNOVIAL JOINTS
(East Carolina University, 2012)Little is understood about the complex process of synovial joint formation in early limb development. It has been shown that versican is highly expressed in the extracellular matrix of these joints (Snow et al., 2005; ... -
Versican Expression during Synovial Joint Morphogenesis
(East Carolina University, 2007-09)The extracellular matrix (ECM) plays a critical role in governing cell behavior and phenotype during limb skeletogenesis. Chondroitin sulfate proteoglycans (Cspgs) are highly expressed in the ECM of precartilage mesenchymal ... -
Visual mate choice in poison frogs.
(East Carolina University, 1999-11-07)We investigated female mate choice on the basis of visual cues in two populations of Dendrobates pumilio, the strawberry poison frog, from the Bocas del Toro Archipelago in Panama, Central America. Mate choice experiments ...
