A Müllerian mimicry ring in Appalachian millipedes
(East Carolina University, 2009-06-16)
Few biological phenomena provide such an elegant and straightforward example of evolution by natural selection as color mimicry among unrelated organisms. By mimicking the appearance of a heavily defended aposematic ...
Catabolite repression control (Crc) gene and Pseudomonas virulence
The present invention relates to a method of screening for compounds that inhibit the virulence of Pseudomonas bacteria and comprises the steps of: providing a culture medium comprising Pseudomonas bacteria, administering ...
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 ...
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 ...
Inbreeding Depression and Mixed Mating in Leptosiphon jepsonii: A Comparison of Three Populations
(East Carolina University, 2006-08)
Background and Aims: Inbreeding depression is thought to play a central role in the evolution and maintenance of cross-fertilization. Theory indicates that inbreeding depression can be purged with self-fertilization, ...
RDX Induces Aberrant Expression of MicroRNAs in Mouse Brain and Liver
(East Carolina University, 2009-02)
Background: Although microRNAs (miRNAs) have been found to play an important role in many biological and metabolic processes, their functions in animal response to environmental toxicant exposure are largely unknown. ...
Posttranslational modifications in the CP43 subunit of photosystem II
(East Carolina University, 2002-11-12)
Photosystem II (PSII) catalyzes the light-driven oxidation of water and the reduction of plastoquinone; the oxidation of water occurs at a cluster of four manganese. The PSII CP43 subunit functions in light ...
RDX and miRNA Expression: Zhang and Pan Respond
(East Carolina University, 2009-03)
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 ...
The evolution of parental care and egg size: a comparative analysis in frogs
(East Carolina University, 2006-03-22)
The evolution of parental care and egg size has attracted considerable attention and theoretical debate. Several different hypotheses have been proposed concerning the trajectories of parental care and egg size evolution ...
