Characterization of Extracellular Polymeric Substances from Acidophilic Microbial Biofilms
(East Carolina University, 2010-05)We examined the chemical composition of extracellular polymeric substances (EPS) extracted from two natural microbial pellicle biofilms growing on acid mine drainage (AMD) solutions. The EPS obtained from a mid-developmental-stage ... -
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 MiR319-Regulated TCPs in Maize Development
(East Carolina University, 1/13/16)Maize produces two inflorescences, the tassel and the ear, that are essential for reproduction. Both inflorescences arise from similar inflorescence primordia and are patterned largely by the same developmental regulators. ... -
Characterization of Pgrmcs and mPRs in oocyte maturation and ovulation in zebrafish (Danio rerio)
(East Carolina University, 2020-06-22)It is well known that progestins initiate important reproductive processes such as oocyte maturation and ovulation in vertebrates. Progestins exert functions through binding to progestin receptors. At least three families ... -
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 Social Status-Dependent Neuromodulation in Zebrafish (Danio rerio)
(East Carolina University, 2017-06-28)In zebrafish (Danio rerio), social interactions between adult males consist of a series of aggressive encounters that ultimately lead to the formation of stable hierarchies of either socially dominant or subordinate animals. ... -
Characterization of the Bone Marrow Microenvironment During the Development of Triple Negative Breast Cancer Metastases
(East Carolina University, 2017-05-05)Triple negative breast cancer (TNBC) is a subtype that lacks expression of progesterone and estrogen receptors, and does not over-express human epidermal growth factor receptor 2 (HER2). TNBC is not responsive to standard ... -
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 ... -
Characterization of the Role of Mcm10 in DNA Replication in Drosophila melanogaster
(East Carolina University, 2013)Replication of the genome and proper formation, and packaging, of chromatin are processes essential to eukaryotic life. Maintenance of epigenetic chromatin states is essential for faithfully reproducing the transcriptional ... -
Characterization of Two Novel Mutants of DNA Polymerase Delta in Drosophila melanogaster
(East Carolina University, 2011)DNA is the genetic material for all living organisms which is constantly being unpackaged, replicated and repackaged. The replication of this genetic material involves numerous different proteins; however, DNA polymerase ... -
Characterizing Environmental and Physicochemical Conditions in Nursery Areas of River Herring in Chowan River, North Carolina
(East Carolina University, 2012)Anadromous fishes such as blueback herring Alosa aestivalis and alewife A. pseudoharengus, utilize sounds, rivers, and tributaries during spawning. Collectively known as river herring, these two ecologically important ... -
Characterizing Interactions of Thioflavin-T with Native Proteins Especially Bovine Serum Albumin
(East Carolina University, 2017-05-03)Thioflavin T is a fluorescent probe used to monitor formation of cross [beta]-sheet rich amyloid fibrils. Involvement of the amyloid fibrils is implicated in more than 50 human diseases, such as Alzheimer's, Parkinson's ... -
Characterizing Multigenerational Effects of Nicotine-Dependent Behaviors in Caenorhabditis Elegans
(East Carolina University, 2017-05-03)This project aims to investigate the effects nicotine, a highly addictive chemical associated with tobacco smoking, have on offspring (F1 and F2) using the model organism Caenorhabditis elegans (C. elegans). C. elegans is ... -
Characterizing the Expression Pattern of miR167-Regulated ZmArf3 and ZmArf30 in Maize Inflorescences
(East Carolina University, 2014)Plant growth and development depends on the activity of meristems, pools of stem cells that generate leaves and other organs. Maize (corn) produces two inflorescences, the tassel and ear, which are patterned by a series ... -
Characterizing the role of the Early Gene at 23 (E23) in Drosophila Melanogaster Oogenesis
(East Carolina University, 2016-04-29)Drosophila melanogaster (fruit fly) females undergo oogenesis to create oocytes from undifferentiated stem cells in the ovary. Similar to estrogen in humans, the steroid hormone ecdysone in fruit flies has a known role in ... -
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 ... -
Chartacterizating the stigma transcriptome of leptosiphon jepsonii
(East Carolina University, 8/5/2020)The majority of angiosperm species are hermaphroditic, containing both male and female reproductive organs on the same plant. This introduces the possibility of reproducing through self-fertilization (selfing) in flowering ... -
