Notch Regulation Of Adam12 Expression In Glioblastoma Multiforme, Ala'a S. Alsyaideh
Notch Regulation Of Adam12 Expression In Glioblastoma Multiforme, Ala'a S. Alsyaideh
Masters Theses 1911 - February 2014
Glioblastoma is the most common malignant brain tumor, accounting for 17% of all primary brain tumors in the United States. Despite the available surgical, radiation, and chemical therapeutic options, the invasive and infiltrative nature of the tumor render current treatment options minimally effective. Recent reports have identified multiple regulators of glioblastoma progression and invasiveness. It has been demonstrated that ADAM12, A Disintegrin And Metalloproteinase encoded by ADAM12 gene, is over-expressed in glioblastoma and directly correlated with tumor proliferation. Additionally, dysregulation of the Notch signaling pathway has been implicated in the pathogenesis of many gliomas. Lastly, an evolving role of microRNAs, …
Structure-Function Analysis Of Nel, A Thrombospondin-1-Like Glycoprotein Involved In Neural Development And Functions, Masaru Nakamoto
Structure-Function Analysis Of Nel, A Thrombospondin-1-Like Glycoprotein Involved In Neural Development And Functions, Masaru Nakamoto
Biology Faculty Publications
Nel (neural epidermal growth factor (EGF)-like molecule) is a multimeric, multimodular extracellular glycoprotein with heparin-binding activity and structural similarities to thrombospondin-1. Nel is predominantly expressed in the nervous system and has been implicated in neuronal proliferation and differentiation, retinal axon guidance, synaptic functions, and spatial learning. The Nel protein contains an N-terminal thrombospondin-1 (TSP-N) domain, five cysteine-rich domains, and six EGF-like domains. However, little is known about the functions of specific domains of the Nel protein. In this study, we have performed structure-function analysis of Nel, by using a series of expression constructs for different regions of the Nel protein. …
A Proposal To Test The Effects Of Factor Ecat1 On Pluripotency, From Reprogramming To Differentiation Of Human Somatic Cells, Vritti R. Goel
A Proposal To Test The Effects Of Factor Ecat1 On Pluripotency, From Reprogramming To Differentiation Of Human Somatic Cells, Vritti R. Goel
CMC Senior Theses
The field of stem cell research has been growing more because of the interest in using stem cells to cure diseases and heal injuries. Human embryonic stem cells, because of the controversy surrounding them—and subsequently the difficulties in acquiring samples of the existing aging cell lines—can only be used in limited capacities. While the development of induced pluripotent stem cells in the last decade has allowed the field to progress closer to medical treatments, the low efficiency of reprogramming a somatic cell to a pluripotent state, and the vast molecular and genomic differences between human embryonic stem cells and human …
Definition Of The Landscape Of Chromatin Structure At The Frataxin Gene In Friedreich’S Ataxia, Eunah Kim
Definition Of The Landscape Of Chromatin Structure At The Frataxin Gene In Friedreich’S Ataxia, Eunah Kim
Dissertations & Theses (Open Access)
Friedreich’s ataxia (FRDA) is caused by the transcriptional silencing of the frataxin (FXN) gene. FRDA patients have expansion of GAA repeats in intron 1 of the FXN gene in both alleles. A number of studies demonstrated that specific histone deacetylase inhibitors (HDACi) affect either histone modifications at the FXN gene or FXN expression in FRDA cells, indicating that the hyperexpanded GAA repeat may facilitate heterochromatin formation. However, the correlation between chromatin structure and transcription at the FXN gene is currently limited due to a lack of more detailed analysis. Therefore, I analyzed the effects of the hyperexpanded GAA …

Interspecies Comparison Of Αii-Spectrin Abundance Between Chinook Salmon And Steelhead, Brielle D. Kemis, Ann L. Miracle, Katie A. Wagner, Christa M. Woodley
STAR Program Research Presentations
Salmonids, such as Chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss), are a staple economic, recreational, tribal, and environmental resource, yet many populations are unsustainable. This study was part of a broad scale effort to monitor the impact of downstream migration obstacles on juvenile salmonid health and survival, which is an essential step towards increasing Smolt-to-Adult Return ratios (SARs). The objective of this study was to determine if juvenile Chinook salmon and steelhead exhibit differing quantities of alphaII-Spectrin Breakdown Products (SBDPs) over two consecutive spring migration periods, indicative of neurogenesis rate and/or biological response to head …
Regulation Of Endothelial Nitric Oxide Synthase In Pulmonary Myofibroblasts, Jonathan David Faughn
Regulation Of Endothelial Nitric Oxide Synthase In Pulmonary Myofibroblasts, Jonathan David Faughn
Masters Theses & Specialist Projects
Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease leading to decreased lung volume and eventual respiratory failure. At present, the median post-diagnosis lifespan is between three and six years. Myofibroblasts are collagen-secreting cells essential for wound healing, but also implicated in the fibroproliferation and extra cellular matrix deposition commonly seen in IPF. The nitric oxide (NO) signaling pathway is implicated in protomyofibroblast to myofibroblast transition and regulation. Previous work has shown that in pulmonary myofibroblasts, endothelial nitric oxide synthase (eNOS) is the primary NOS isoform expressed. The current study used cultured rat pulmonary myofibroblasts between passages two and five …
The Role Of The Androgen Receptor Cofactor P44/Wdr77 In Astrocyte Activation, Bryce H. Vincent
The Role Of The Androgen Receptor Cofactor P44/Wdr77 In Astrocyte Activation, Bryce H. Vincent
Dissertations & Theses (Open Access)
Astrogliosis is induced by neuronal damage and is also a pathological feature of the major aging-related neurodegenerative disorders. The mechanisms that control the cascade of astrogliosis have not been well established. In a previous study, we identified a novel androgen receptor (AR)-interacting protein (p44/WDR77) and found that it plays a critical role in the control of proliferation and differentiation of prostate epithelial cells. In the present study, we found that deletion of the p44 gene in the mouse brain caused accelerated aging with dramatic astrogliosis. The p44/WDR77 is expressed in astrocytes and loss of p44/WDR77 expression in astrocytes leads to …

STUDY OF REST AS A NEGATIVE REGULATOR OF P16INK4A
Monica Gireud, B.S.
Thesis Advisor: Vidya Gopalakrishnan, Ph.D.
The RE1 Silencing Transcription Factor (REST) is a negative regulator of neuronal differentiation. It is expressed ubiquitously in early embryos, but downregulated in neural progenitors concomitant with onset of neuronal differentiation in these cells. REST has been widely studied as a negative regulator of neuronal differentiation genes. Our recent work identified a novel role for REST in control of cell proliferation. However, the underlying molecular mechanism(s) are not known and is a focus of the current thesis project. Here, we provide evidence …

Delineating the mechanism(s) of BDNF/TrkB mediated proliferation in Neuroblastoma
Timothy Christopher Graham, B.S.
Supervisory Professor: Patrick Zweidler-McKay, MD/PhD
Neuroblastoma is the most common extra-cranial solid tumor in children, arising from neural crest precursor cells. The neurotrophin receptors (TrkA/B/C) have been implicated as important prognostic markers, linking the biology of the tumor to patient outcome. High expression of TrkA and TrkC receptors have been linked to favorable biological features and high patient survival, while TrkB is expressed in unfavorable, aggressive tumors. Several studies suggest that high levels and activation of TrkB by its ligand brain-derived neurotrophic factor (BDNF) stimulates tumor cell …
Modulation Of Glutamate-Mediated Neuronal Cell Death By Neurosteroids, Benjamin J. Phelps
Modulation Of Glutamate-Mediated Neuronal Cell Death By Neurosteroids, Benjamin J. Phelps
Undergraduate Theses and Capstone Projects
Traumatic brain injury (TBI) is a major cause of death and permanent disability in the United States. Approximately 1.7 million cases of TBI are reported annually. After an injury to the head, excessive glutamate, an excitatory neurotransmitter, is released into the extracellular fluid resulting in the excitotoxic death of neuronal tissue. Recent studies have suggested neurosteroids, may serve as an effective means by which to modulate excitotoxicity via the excitatory neurotransmitter alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA). Using mixed astrocyte-neuronal cell cultures (14-16 DIV) exposed to increasing concentrations of AMPA as the model for TBI, the experiments examined the effect of the neurosteroids, …
Sex Difference In Calbindin Cell Number In The Mouse Preoptic Area: Effects Of Neonatal Estradiol And Bax Gene Deletion, Richard F. Gilmore Iii
Sex Difference In Calbindin Cell Number In The Mouse Preoptic Area: Effects Of Neonatal Estradiol And Bax Gene Deletion, Richard F. Gilmore Iii
Masters Theses 1911 - February 2014
The sexually dimorphic nucleus of the preoptic area (SDN-POA) was first discovered in rats and is one of the most famous and best studied sex differences in the field of neuroscience. Though well documented in rats (larger in males than females), this sex difference was only recently able to be observed in mice due to the discovery of the protein calbindin-D28k as a marker. Recent studies have shown a larger, more distinct calbindin-immunoreactive (ir) cell cluster in male mice compared to females. However, the exact location of the cluster and whether the sex difference is one of total cell number …

Nel is a glycoprotein containing five chordin-like and six epidermal growth factor-like domains and is strongly expressed in the nervous system. In this study, we have examined expression patterns and in vitro functions of Nel in the chicken retinotectal system. We have found that in the developing tectum, expression of Nel is localized in specific laminae that retinal axons normally do not enter, including the border between the retinorecipient and non-retinorecipient laminae. Nel-binding activity is detected on retinal axons both in vivo and in vitro, suggesting that retinal axons express a receptor for Nel. In vitro, Nel inhibits retinal axon …

BACKGROUND: Regulatory T lymphocytes (Treg) infiltrate human glioblastoma (GBM); are involved in tumor progression and correlate with tumor grade. Transient elimination of Tregs using CD25 depleting antibodies (PC61) has been found to mediate GBM regression in preclinical models of brain tumors. Clinical trials that combine Treg depletion with tumor vaccination are underway to determine whether transient Treg depletion can enhance anti-tumor immune responses and improve long term survival in cancer patients. FINDINGS: Using a syngeneic intracrabial glioblastoma (GBM) mouse model we show that systemic depletion of Tregs 15 days after tumor implantation using PC61 resulted in a decrease in Tregs …

Glialcell line-derived neurotrophicfactor (GDNF) has been regarded as a potent survival factor for a subpopulation of neurons. It has been shown that GDNF expression is upregulated in skeletal muscle of patients with early stage of neuromuscular diseases such as amyotrophic lateral sclerosis (ALS). Previous results from our laboratory showed that neural cells regulate GDNF secretion by skeletal muscle; non-innervated skeletal muscle appear to secrete more GDNF compared to innervated skeletal muscle. Two aims were examined in the current study. First, to examine whether neural cells inhibit GDNF through acetylcholine release. Second was to examine whether differentiated NG108-15 neural cells secrete …

Glial-cell line derived neurotrophic factor (GDNF) is a neurotrophic factor produced by skeletal muscle. GDNF has been shown to be potent survival factor for motor neurons. We have previously shown that GDNF content in skeletal muscle is altered following exercise and GDNF levels 24 hours after the last bout of exercise are significantly different than those measured immediately after exercise. We sought to determine how long after exercise do GDNF protein levels remain altered. We removed extensor digitorum longus (EDL) and Soleus (SOL), 24 hr, 72 hr and 1 week following the last bout of involuntary exercise. Muscles were processed …

Toxic insult by PCBs results in learning and memory deficits in humans. Alterations in expression of neurotrophic factors and/or their receptors have been linked to changes in cognition. How PCBs affect cognition is not known. We propose that PCBs affect cognition by altering neurotrophic factor expression or effects. We exposed cultured C6 glial cells in medium containing PCB (Aroclor 1254 (10ppm)). Control cells were treated with DMSO or regular medium. Cells were incubated at 37o C for up to 72 hours. Medium samples were taken at 6hr, 24hr, 48hr, and 72hr intervals. Enzyme-linked immunosorbent assays (ELISA) were used to determine …

Neural maps in the vertebrate central nervous system often show discontinuously segregated, domain-to-domain patterns. However, the molecular mechanism that establishes such maps is not well understood. Here we show that in the chicken olivocerebellar system, EphA receptors and ephrin-As are expressed with distinct levels and combinations in mapping domains. When ephrin-A2 is retrovirally overexpressed in the cerebellum, the olivocerebellar map is disrupted, excluding axons with high receptor activity from ectopic expression domains. Conversely, overexpression of a truncated EphA3 receptor in the cerebellum reduces endogenous ligand activity to undetectable levels and causes aberrant mapping, with high receptor axons invading high ligand …
