Investigating the Role of CtBP in Colorectal Cancer
(2015-04-29)Recent studies in breast cancer tissue have demonstrated that C-terminal binding protein (CtBP) over-expression induces stem cell-like features and genome instability; whereas CtBP depletion or caloric restriction reverses ... -
IS PREDATION BY TURTLES SUFFICIENTLY STRONG TO AFFECT BIODIVERSITY WITHIN FISHLESS PONDS?
(East Carolina University, 2011)Ecologists have long known that predation can have a strong effect on the diversity and abundance of prey in ecological communities. Much evidence on the importance of predation in aquatic systems has stemmed from studies ... -
The largest subunit of RNA polymerase II from the Glaucocystophyta: functional constraint and short-branch exclusion in deep eukaryotic phylogeny
(East Carolina University, 2005-12)Background: Evolutionary analyses of the largest subunit of RNA polymerase II (RPB1) have yielded important and at times provocative results. One particularly troublesome outcome is the consistent inference of independent ... -
Lateral Gene Transfer between Bacteria and Trichoderma reesei
(East Carolina University, 2012)Lateral gene transfer (LGT) has played an important role in shaping the `tree of life'. It has promoted evolution by generating gene redundancies, which allow for more freedom in terms of allowed mutations in a genome, ... -
Life History Aspects of the Hickory Shad (Alosa Mediocris) in the Albemarle Sound/ Roanoke River Watershed, North Carolina
(East Carolina University, 1998-01)The hickory shad (Alosa mediocris), which supports commercial and recreational fisheries in the Roanoke River and Albemarle Sound, North Carolina, is an anadromous species closely related to the American shad (A. sapidissima). ... -
Local and Regional Aspects of Habitat Quality Jointly Affect the Biodiversity of Ephemeral Ponds
(East Carolina University, 2012)The biodiversity of local communities is likely affected by both local habitat quality and by the quality of the landscape surrounding the locality. In pond environments, habitat quality may be affected by the kind of leaf ... -
LOCALIZATION AND CHANGES OF NUCLEAR PROGESTERONE RECEPTORS IN ZEBRAFISH OOCYTES AND ADJACENT FOLLICULAR CELLS
(East Carolina University, 2010)The nuclear progesterone receptor (Pgr) is one of the major mediators for progestin signaling during oocyte ovulation in vertebrates. However, any roles Pgr may play in oocyte growth, and especially in the final oocyte ... -
The Manganese Transporter MntH Is a Critical Virulence Determinant for Brucella abortus 2308 in Experimentally Infected Mice
(East Carolina University, 2009-08)The gene designated BAB1_1460 in the Brucella abortus 2308 genome sequence is predicted to encode the manganese transporter MntH. Phenotypic analysis of an isogenic mntH mutant indicates that MntH is the sole high-affinity ... -
Maturation and fecundity of the Neuse and Tar-Pamlico Rivers striped bass (morone saxatilis) stocks in coastal North Carolina
(East Carolina University, 1/13/16)The Albemarle/Roanoke stock makes up the largest contingent of Striped Bass (Morone saxatilis) in the state; however, other economically important populations exist elsewhere. The Central Southern Management Area (CSMA) ... -
Maturation, Fecundity, and Spawning Frequency of the Albemarle/Roanoke Striped Bass Stock
(East Carolina University, 2011)The principal striped bass, Morone saxatilis population in North Carolina, the Albemarle/Roanoke (A/R) stock has grown tremendously in size and age structure over the last twenty years necessitating an up-to-date maturity ... -
Metabolic, Physiological, And Behavioral Responses Of Prey To Predation
(East Carolina University, 2015)Predators are known to cause prey to alter their morphology, life history or behavior in ways that reduce the likelihood of the prey being consumed by the predator. Seldom considered, however, are the consequences of ... -
Method of treating anxiety-related disorders with 2-aminocycloaliphatic amide compounds
(1995-12-12)A method for combatting anxiety in a subject in need of such treatment is provided. The method comprises administering to the subject a 2-aminocycloaliphatic amide kappa opioid agonist in an effective anxiety-combatting amount. -
MHC class I variation among wild, domestic and insular populations of the zebra finch (Taeniopygia guttata)
(East Carolina University, 2014)The zebra finch (Taeniopygia guttata) is a passerine bird native to Australia and the Lesser Sunda Islands, with domesticated populations derived from each of these localities. The Lesser Sundas and domesticated zebra ... -
Microarray and pathway analysis reveals decreased CDC25A and increased CDC42 associated with slow growth of BCL2 overexpressing immortalized breast cell line
(East Carolina University, 2008-10)Bcl-2 is an anti-apoptotic protein that is frequently overex-pressed in cancer cells but its role in carcinogenesis is not clear. We are interested in how Bcl-2 expression affects non-cancerous breast cells and its role ... -
Microbial Carbon Assimilation within the Walls of Deep-sea Hydrothermal Vent Chimneys
(East Carolina University, 2011)Carbon is one of the most abundant elements on Earth stored in a multitude of reservoirs and constantly cycled through various processes occurring on our planet. Although it represents only a small percentage of the total ... -
MICROBIAL DIVERSITY AND BIOGEOGRAPHY IN A SERPENTINITE-HOSTED ECOSYSTEM
(East Carolina University, 2010)The goal of this project was to characterize the taxonomic and functional diversity and document biogeographic patterns of microbial communities in an ecosystem influenced by active serpentinization. Serpentinization is a ... -
Mismatched anti-predator behavioral responses in predator-naïve larval anurans
(2015-12-07)Organisms are adept at altering behaviors to balance the tradeoff between foraging and predation risk in spatially and temporally shifting predator environments. In order to optimize this tradeoff, prey need to be able to ... -
Molecular and Cellular Biology Animations: Development and Impact on Student Learning
(East Carolina University, 2005)Educators often struggle when teaching cellular and molecular processes because typically they have only two-dimensional tools to teach something that plays out in four dimensions. Learning research has demonstrated that ... -
Molecular Epidemiology of MRSA Among Patients and Employees in a Surgical Intensive Care Unit
(East Carolina University, 2011)Methicillin-resistant Staphylococcus aureus (MRSA) is a pervasive drug resistant human pathogen and has become widespread in hospitals around the world. MRSA infections cause approximately 19,000 deaths among hospitalized ... -
Molecular phylogenetic evidence for a mimetic radiation in Peruvian poison frogs supports a Müllerian mimicry hypothesis.
(East Carolina University, 2001-12-07)Examples of Müllerian mimicry, in which resemblance between unpalatable species confers mutual benefit, are rare in vertebrates. Strong comparative evidence for mimicry is found when the colour and pattern of a single ...
