Locating Mutagen-Sensitivity Gene Mus109 In The Drosophila Melanogaster Genome Using Deficiency Mapping, Chandani Mitchell
The Winthrop McNair Research Bulletin
The complex processes involved in repairing damaged DNA are still being elucidated. Some genes that are known to have roles in the DNA repair process have been identified, such as the mutagen-sensitivity genes, or mus genes, in Drosophila melanogaster. However, the precise genomic location of some mus genes is still unknown, including mus109. It is known that mutations in mus109 cause chromosomal aberrations resulting in larval death, and previous research has mapped mus109 to a region of the X chromosome consisting of over 520,000 nucleotides and 41 genes. Therefore, this study aimed to locate mus109 using deficiency mapping. The mus109D2 …

Ngly1 Deficiency Affects Glycosaminoglycan Biosynthesis And Wnt Signaling Pathway In Mice, Amy Batten
PANDION: The Osprey Journal of Research and Ideas
Individuals affected by NGLY1 Deficiency cannot properly deglycosylate and recycle certain proteins. Even though less than 100 people worldwide have been diagnosed with this rare autosomal recessive condition, thousands are affected by similar glycosylation disorders. Common phenotypic manifestations of NGLY1 Deficiency include severe neural and intellectual delay, impaired muscle and liver function, and seizures that may become intractable. Very little is currently known about the various mechanisms through which NGLY1 deficiency affects the body and this has led to a lack of viable treatment options for those afflicted. This experiment uses a loss-of-function (LOF) mouse model of NGLY1 Deficiency homologous …
Targeting Of The Hedgehog Signaling Pathway In Cancer Treatment,

Targeting Of The Hedgehog Signaling Pathway In Cancer Treatment, Andrew J. Hawes
The Cardinal Edge
The Hedgehog (Hh) signaling pathway is a developmental pathway that is highly conserved evolutionarily. While typically only displaying high activity during embryogenesis, overactivation of the Hh pathway in adults has been linked to multiple forms of cancer including acute myeloid leukemia, myelofibrosis, basal-cell carcinoma, pancreatic ductal adrenal carcinoma, and triple negative breast cancer. The prevalence of Hh activation in many different cancers has made it a prime target for inhibition of these cancers through novel therapies. This literature review sought to assess the current state of cancer treatment through inhibition of Hh signaling. Most current clinical trials involving the pathway …

Dissertations - ALL
The mammalian neocortex develops from a thin layer of neuroepithelial cells into a robust mosaic of differentiated neurons organized into distinct layers and functional areas. This process requires a complex choreography of transcription factors and epigenetic regulators to be spatially and temporally activated in a precise manner. Disruptions in any aspect of this delicate process may lead to neurodevelopmental disorders like autism spectrum disorder, schizophrenia, or intellectual disability. One such transcriptional coregulator that is a crucial regulator of neocortical development is Cited2. Previous work demonstrated that forebrain-specific Cited2 loss-of-function causes a reduction in neocortical progenitor proliferation which leads to reduced …

Electronic Theses and Dissertations
Protein prenylation, a common lipid post-translational modification, is required for growth and development in eukaryotes. Rab geranylgeranylation involves the addition of one or two 20-carbon geranylgeranyl moieties to Rab-GTPase target proteins, which regulate intracellular vesicle trafficking. The reaction is carried out by heterodimeric Rab geranylgeranyltransferase (Rab-GGT), which is composed of two associated α- and β-subunits, with the assistance of an additional protein called Rab escort protein (REP). Loss of function of the Rab-GGT α subunit RGTA1 has not been reported in any plant. While knockout of either of the two β subunits RGTB1 or RGTB2 results in …

Legacy Theses & Dissertations (2009 - 2024)
Myogenesis involves skeletal muscle stem cells (MuSCs) that produce and regenerate skeletal muscle during regular growth and repair. However, when this system fails to function normally, it can lead to musculoskeletal diseases like Duchenne Muscular Dystrophy (DMD). Therefore, it is important to study the molecular mechanisms behind this developmental process in order to seek therapies and solutions for these types of diseases. Our interest lies in the field of epitranscriptomics, which focuses on post-transcriptional ribonucleic acid (RNA) modifications, particularly N6-methyladenosine (m6A), which involves the addition of a methyl group to the adenosine nucleotide, a process that is mediated by the …

Regeneration is a complex process to replace or restore tissue after damage. However, animals vary in their ability to regenerate tissue, and humans are limited in their abilities. Understanding how regeneration occurs in highly regenerative vertebrates, such as in Xenopus laevis frogs will lead to defining common regeneration mechanisms. In recent years, eye regeneration research in Xenopus laevis tadpoles provided new promising insight into the mechanisms necessary for repair of damaged eye tissue. Much progress has been made towards understanding the regenerative capability of the complex eye since Xenopus tadpoles can regenerate mature eye tissues, including: the optic nerve, retina, …

Dissertations and Theses (Open Access)
Congenital anomalies of the kidney and urinary tract (CAKUT) accounts for nearly one-fourth of all birth defects and more than 40% of pediatric end-stage renal disease, yet only 10-20% of CAKUT cases have a known monogenetic cause. Human kidneys are composed of up to a million epithelial tubules called nephrons. Disruption of nephron development is one of the many congenital anomalies that cause CAKUT, often resulting in chronic or end-stage renal disease which requires transplant. During nephron epithelialization, the formation of stable cadherin-mediated adhesion junctions is essential for maintaining cell-cell contacts. To understand the cell behaviors underlying abnormalities in renal …
Investigations Into Avian Skeletal Adaptations And Spine Fusion Events,

Investigations Into Avian Skeletal Adaptations And Spine Fusion Events, Tori Huey
All Theses
Avian dinosaurs evolved skeletal adaptations resulting in numerous fused spinal structures, like the synsacrum, present in extant birds. The synsacrum is a highly fused region necessary for stiffening the spine, and it fuses the spine to the pelvic ilium. Conventional wisdom suggests that fusion occurred in ovo during embryonic development via the cartilage matrix that patterns the future vertebrae. We show that post hatch birds have intervertebral discs separating all vertebrae of the spine, leading us to re-examine this notion in chickens up to 10 weeks of age. Intervertebral discs undergo constant remodeling, then degenerate and undergo tissue clearance, followed …

Motor developmental delay (MDD) usually affects the inter-joint coordination for limb movement. However, the mechanism between the abnormal inter-joint coordination and MDD is still unclear, which poses a challenge for clinical diagnosis and motor rehabilitation of MDD in infant’s early life. This study aimed to explore whether the joint activities of limbs during infant crawling are represented with kinematic synergies of joint angles, and evaluate the impacts of MDD on the inter-joint coordination using those synergies. 20 typically developing infants, 16 infants at risk of developmental delay, 11 infants at high risk of developmental delay and 13 infants with confirmed …

Honors Scholar Theses
FOP is a rare genetic disorder in which skeletal muscle and associated connective tissue progressively turn to bone through a process called heterotopic ossification (HO). The extra skeletal bone growth is cumulative, eventually trapping patients in a second skeleton that eventually leads to death by asphyxiation. The FOP mutation is autosomal dominant that can be inherited or acquired sporadically. Unfortunately, FOP is currently incurable with no therapeutic options to inhibit bone growth or reduce existing bone nodules. My project intends to further our understanding of the cellular mechanisms of the disease within the tongue muscle. A population of cells known …

The Effects Of Aging On Wound Healing And Limb Regeneration In The Axolotl, Hande Sahin
Graduate Masters Theses
The Mexican axolotl is capable of regenerating various parts of its body and maintains this capacity throughout its entire life. Although this ability is sustained through adulthood, multiple regenerative processes appear to be negatively affected by aging. Here, we focus on evaluating the effect of aging on the rate of wound healing and limb regeneration. We have developed new in vivo, and ex vivo assays to characterize wound healing and identify differences between young and aged animals during this process. We have also characterized morphological features of mature skin from both groups of animals and although there are no obvious …

The species Xenopus laevis is native to sub saharan Africa, but ever since its discovery in effectiveness in pregnancy tests, the frog now lives invasively around the world. Today the Xenopus Laevis is used mostly in laboratories as a model organism for studying developmental biology (Willigan 2001). The commercialized herbicide Atrazine, has been found to interact with this model organism species in an odd way you might not have guessed (Sanders 2010). Atrazine is primarily absorbed in the gastrointestinal tract and has been shown to have neuroendocrine, reproductive, and developmental effects on experimental animals such as Xenopus laevis (ATSDR 2004). …

When Problems Become Solutions: Harnessing The Osteogenic Capacity Of Disease-Causing Stem Cells To Repair Bone Fractures, Mehreen Pasha
University Scholar Projects
While we often perceive disease as negative, there is potential to engineer seemingly negative biological phenomena into therapeutics to treat a variety of human illnesses. Fibrodysplasia ossificans progressiva (FOP) is a genetic disorder involving uncontrolled, widespread, extraskeletal bone growth, or heterotopic ossification (HO). In FOP patients, stem cells called fibro/adipogenic progenitors (FAPs) follow an abnormal, osteogenic pathway. In the present study, we investigate whether we can adapt these Acvr1 mutant FAPs, which are exceptional at producing bone, to repair bone fractures in otherwise normal patients. The primary aims of this study are (1) to devise and optimize a novel method …

Characterization Of Gangliosides And Fatty Acids In Extracellular Vesicles From Human Milk, Aliya Amin
Food Science (MS) Theses
Extracellular vesicles (EVs) are bioactive components of human milk that may impact functionality to regulate growth, cognitive development, metabolism, and immunity in newborns. The biogenesis of EVs and the mechanism by which EVs elicit biologic effects in vivo have not been characterized entirely. Gangliosides and fatty acids are integral in the formation, release, stability, and functionalities of EVs. Presumably, EV function is related to EV composition and lipids in EVs influence the bioavailability of EV cargo and downstream functions of EVs. The objective of this research was to characterize the fatty acid and ganglioside composition of EVs in human milk. …

Translation Control Tunes Drosophila Oogenesis, Elliot T. Martin
Legacy Theses & Dissertations (2009 - 2024)
The decision of a stem cell to either self-renew or differentiate is controlled by specific cellularpathways that can act at the level of transcription, translation, or post-translation. To study the regulation of these pathways in-vivo, I have used the female Drosophila germline as a model system. Each of the steps from germline stem cell (GSC) to egg require changes in cellular pathways. These changes can occur at the level of transcription, post-transciption, translation, or post-translation . Decades of research has elucidated many of the changes to gene that occur during oogenesis, however, many players in this process still remain mysterious. …
