Characterizing the vegetative phenotype of fzt maize mutant
(East Carolina University, 2012)microRNAs are short, non-coding RNA strands that regulate gene expression post-transcriptionally in all multicellular organisms. miRNAs begin as a hairpin in the nucleus. The primary miRNA (pri-miRNA) and preliminary ... -
Comparison of ZnO nanoparticles and ZnCl₂ induced germ cell apoptosis in Caenorhabditis elegans
(East Carolina University, 2014)There is inadequate research data available on manufactured ZnO nanoparticles. Manufactured nanoparticles are widely used in various products and production of manufactured nanoparticles is becoming increasingly abundant. ... -
Development of Computational Tools and Resources for Cotton microRNA Analysis
(East Carolina University, 2014)MicroRNAs (miRNAs) are an extensive class of small regulatory RNAs which regulate gene expression at the posttranscriptional levels. miRNAs target genes for mRNA cleavage or translation inhibition based on the complementary ... -
DIFFERENTIAL GENE EXPRESSION IN THE BRAINS OF BEGGING POISON FROG TADPOLES
(East Carolina University, 8/5/2020)Parents often rely on offspring signals to adequately allocate resources to dependent offspring. The mimic poison frog, Ranitomeya imitator, has evolved elaborate parental care behaviors to raise their young. Their tadpoles ... -
Effects of Nicotine on Caenorhabditis elegans survival, reproduction, and gene expressions : Development of an Invertebrate Animal Model for Drugs of Abuse
(East Carolina University, 2011)Although much is known about the addictive effects of nicotine, the molecular mechanisms of nicotine-induced effects remain largely unclear. Specifically, little is known about the effects of nicotine on gene expression, ... -
The effects of sodium butyrate on Hox gene expression in a human colorectal adenocarcinoma cell line, HT29.
(East Carolina University, 2013)Hox genes are a subgroup of the large family of homeobox containing genes, known to pattern anterior/posterior and proximal/distal axes during embryonic development. More recently Hox gene research has focused on the role ... -
THE EVOLUTION OFHOX [sic] PARALOG GROUP 2 GENE EXPRESSION AND REGULATION IN THE JAPANESE MEDAKA
(East Carolina University, 2011)Hox paralog group 2 (PG2) genes are evolutionarily conserved developmental regulatory genes that function to specify rhombomere (r) and pharyngeal arch (PA) identities in animal embryos. Several rounds of whole genome ... -
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 ... -
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 ... -
Genetic regulation of maize floral development - insights from the transcriptome and translatome
(East Carolina University, 2022-06-24)Flowers are produced by floral meristems, groups of stem cells that give rise to floral organs. In grasses, including the major cereal crops, flowers (florets) are contained in spikelets, which contain one to many florets, ... -
Hox Gene Expression During Oreochromis niloticus Pharyngeal Arch Development : Discovering the Hox Code
(East Carolina University, 2010)Hox genes encode transcription factors and have been extensively studied by evolutionary and developmental biologists. Hox genes are responsible for determining specific regional identities along the anterior-posterior and ... -
Investigating candidate genes for an association with skin color pattern in the mimic poison frog Ranitomeya imitator
(East Carolina University, 8/5/2020)Understanding the genetic basis of adaptive traits can help us better understand their evolution. The mimic poison frog, Ranitomeya imitator, is native to Peru. Like many other species of poison frogs, it has aposematic ... -
SPATIAL EXPRESSION OF MATRIX AND MATRIX RECEPTOR PROTEINS IN THE DEVELOPING SYNOVIAL JOINT
(East Carolina University, 2013)Little is understood about the complex spatial and temporal molecular interactions necessary to form a fully functional synovial joint. Understanding molecular pathways and signaling within the developing joint continues ...
