Footprints in the sand: independent reduction of subdigital lamellae in the Namib–Kalahari burrowing geckos
(East Carolina University, 2006-04-07)Many desert organisms exhibit convergence, and certain physical factors such as windblown sands have generated remarkably similar ecomorphs across divergent lineages. The burrowing geckos Colopus, Chondrodactylus and ... -
A Functional Analysis of microRNAs in Nicotiana tabacum
(East Carolina University, 2012)MicroRNAs (miRNAs) are a newly discovered class of endogenous post-transcriptional gene regulators that are typically 20-22 nucleotides in length that do not code for proteins. MiRNAs regulate gene expression by either ... -
Functional Unit of the RNA Polymerase II C-Terminal Domain Lies within Heptapeptide PairsÂ
(East Carolina University, 2004-06)Unlike all other RNA polymerases, the largest subunit (RPB1) of eukaryotic DNA-dependent RNA polymerase II (RNAP II) has a C-terminal domain (CTD) comprising tandemly repeated heptapeptides with the consensus sequence ... -
FUNCTIONS OF G-PROTEIN COUPLED ESTROGEN RECEPTOR (GPER) IN FEMALE ZEBRAFISH REPRODUCTION
(East Carolina University, 2019-11-27)Abstract Steroid hormones such as estrogen depend on receptors like Estrogen Receptor alpha (ERα) and Estrogen Receptor (ERβ) to mediate their slow “genomic” functions, and G-Protein coupled Estrogen Receptor (GPER) to ... -
The Fur-like regulator Mur controls the expression of the gene encoding the manganese transporter MntH in Brucella abortus 2308 in response to manganese availability
(East Carolina University, 2011)Brucella abortus is a Gram-negative, [alpha]-proteobacterium that causes bovine brucellosis, a prevalent zoonotic disease in many areas of the world. Brucella abortus is an intracellular pathogen that survives and ... -
Gamma Protocadherin Expression in the Embryonic Chick Nervous System
(East Carolina University, 2007)Protocadherin gamma (pcdh-gamma) family expression was examined in the embryonic chick central nervous system by in situ hybridization. Transcripts were visualized in discrete regions of fore-, mid-, and hindbrain at stages ... -
Gene Expression and the Evolution of Reduced Sexual Dimorphism in a Threespine Stickleback Color Trait
(East Carolina University, 2017-01-03)Elucidating the processes and mechanisms responsible for sexual dimorphism has been a central task for evolutionary biologists since Darwin first proposed the concept of sexual selection. However, our understanding of the ... -
Gene Expression Divergence Between Zebra Finch (Taeniopygia Guttata) Subspecies And Gene Regulation In Hybrids
(East Carolina University, 2015)Since the publication of Mayr's Systematics and the Origin of Species, birds have been important model organisms for studies regarding evolutionary processes such as sexual selection and speciation. In this study, I will ... -
Gene Regulatory Evolution During Speciation in a Songbird

Genetic Architecture of Conspicuous Red Ornaments in Female Threespine Stickleback
(2015-12)Explaining the presence of conspicuous female ornaments that take the form of male-typical traits has been a longstanding challenge in evolutionary biology. Such female ornaments have been proposed to evolve via both ... -
Genetic associations at 53 loci highlight cell types and biological pathways relevant for kidney function
(2016-01)Reduced glomerular filtration rate defines chronic kidney disease and is associated with cardiovascular and all-cause mortality. We conducted a meta-analysis of genome-wide association studies for estimated glomerular ...
