Bichir HoxA Cluster Sequence Reveals Surprising Trends in Ray-Finned Fish Genomic Evolution
(East Carolina University, 2004-01)The study of Hox clusters and genes provides insights into the evolution of genomic regulation of development. Derived ray-finned fishes (Actinopterygii, Teleostei) such as zebrafish and pufferfish possess duplicated Hox ... -
Bioenergetics and Trophic Impacts of Invasive Indo-Pacific Lionfish
(East Carolina University, 2010)Indo-Pacific lionfish, Pterois volitans and Pterois miles, are non-native marine fish with established populations in the western North Atlantic Ocean and Caribbean Sea. Rapid population growth threatens native fish ... -

Cadherins in maternal-foetal interactions: red queen with a green beard?
(East Carolina University, 2005-03-22)Cadherins are homophilic cell surface adhesion proteins, some of which mediate interactions between maternal and foetal tissues during mammalian pregnancy. David Haig suggested that these proteins may exhibit ‘green-beard ... -
CAN NUTRIENT ADDITIONS MEDIATE GAPE LIMITED PREDATION IN LARVAL RANA SPHENOCEPHALA?
(East Carolina University, 2013)Some predators are limited in the size prey item that they can catch and consume, and this is referred to as "gape limited". Prey found with these predators may have the ability to respond by growing rapidly to reach a ... -
Can Passive Acoustics be Used to Estimate the Length of Atlantic Croaker (Micropogonias undulatus) within the Pamlico Estuary?
(East Carolina University, 2010)The Atlantic States Marine Fisheries Council (AFMFC) attributes the decline in the Atlantic croaker (Micropogonias undulatus) stock to over-fishing practices. The majority of collected Atlantic croaker are small, young of ... -
Cardiac and Mitochondrial Adaptations in Response to Aging and Doxorubicin in Rats Bred for Divergent Aerobic Capacities
(East Carolina University, 2012)Doxorubicin (DOX) remains as one of the most widely prescribed and effective anticancer agents. A major limitation of the therapeutic effectiveness of the drug is the occurrence of irreversible, progressive, dose-dependent ... -
CHARACTERIZATION OF MIGRATING NEURAL CREST CELLS FROM HINDBRAIN EXPLANTS IN ZEBRAFISH
(East Carolina University, 2010)Our lab was interested in creating a reproducible mechanism for obtaining neural crest cells in culture from cultured hindbrain explants of zebrafish. We have characterized the population of cells migrating from the ... -
Characterization of Site-Directed Mutants in the Cytochrome c-550 Protein of Photosystem II
(East Carolina University, 2010)Photosynthesis is the process by which cyanobacteria, algae, and higher plants convert light energy to chemical energy via the biosynthesis of carbohydrates. Photosystem II is a multi-protein/pigment complex embedded in ... -
Characterization of the GINS subunit psf1 in Drosophila Melanogaster
(East Carolina University, 2010)GINS (Go Ichi Ni San; 5,1,2,3 in Japanese) is a heterotetrameric protein complex known to be essential for the establishment of DNA replication forks and the progression of the replisome. The GINS complex is known to be ... -
Cloning, expression, and characterization of a membrane progestin receptor and evidence it is an intermediary in meiotic maturation of fish oocytes
(East Carolina University, 2003-03-04)The structures of membrane receptors mediating rapid, nongenomic actions of steroids have not been identified. We describe the cloning of a cDNA from spotted seatrout ovaries encoding a protein that satisfies the following ... -
Coevolutionary analysis of Appalachian Xystodesmid millipedes and their symbiotic Mesostigmatid mites
(East Carolina University, 2010)Mites (Acari) form symbiotic relationships with many animal taxa including fish, amphibians, reptiles, birds, mammals, mollusks, and arthropods. They are frequently found living on millipedes, and it has often been ... -
Comparative genomics of cyclin-dependent kinases suggest co-evolution of the RNAP II C-terminal domain and CTD-directed CDKs
(East Carolina University, 2004-09-20)Background: Cyclin-dependent kinases (CDKs) are a large family of proteins that function in a variety of key regulatory pathways in eukaryotic cells, including control over the cell cycle and gene transcription. Among the ... -
Comparison of the exoS Gene and Protein Expression in Soil and Clinical Isolates of Pseudomonas aeruginosa
(East Carolina University, 2001-04)Exoenzyme S (ExoS) is translocated into eukaryotic cells by the type III secretory process and has been hypothesized to function in conjunction with other virulence factors in the pathogenesis of Pseudomonas aeruginosa. ... -
Concerted gene recruitment in early plant evolution
(East Carolina University, 2008-07)Background: Horizontal gene transfer occurs frequently in prokaryotes and unicellular eukaryotes. Anciently acquired genes, if retained among descendants, might significantly affect the long-term evolution of the recipient ... -
Consequences of Reduced Versican Expression in Embryonic Chick Synovial Joint Development
(East Carolina University, 2012)The different mechanisms involved in vertebrate synovial joint development are actively being uncovered. A variety of studies have thus far discovered the involvement of several large molecules in the processes of joint ... -
Conspicuous female ornamentation and male mate preference of Threespine Sticklebacks (Gasterosteus aculeatus)
(East Carolina University, 2012)Sexual selection drives the evolution of exaggerated male ornaments (traits showing little function outside social interactions) in many animal species. Female ornamentation is now acknowledged also to be common but is ... -

DEHP Impairs Zebrafish Reproduction by Affecting Critical Factors in Oogenesis
(East Carolina University, 2010-04-15)Public concerns on phthalates distributions in the environment have been increasing since they can cause liver cancer, structural abnormalities and reduce sperm counts in male reproductive system. However, few data are ... -
Did an ancient chlamydial endosymbiosis facilitate the establishment of primary plastids?
(East Carolina University, 2007-06)Background: Ancient endosymbioses are responsible for the origins of mitochondria and plastids, and they contribute to the divergence of several major eukaryotic groups. Although chlamydiae, a group of obligate intracellular ...
