Restructuring Of The Axon Initial Segment In Mouse Models Of Neurodevelopmental Disorders, Rachel Ali Rodriguez
Restructuring Of The Axon Initial Segment In Mouse Models Of Neurodevelopmental Disorders, Rachel Ali Rodriguez
UNLV Theses, Dissertations, Professional Papers, and Capstones
Neurodevelopmental disorders (NDDs) affect more than 36% of children in countries with low- and middle- incomes (Boivin, 2015; McCoy, 2016). Interestingly, these heterogeneous disorders share a high incidence of epileptic seizures, suggesting a shared pathology. Seizures result when neuronal firing activity becomes disturbed and neurons fire excessively or in unregulated patterns. A key site in the control of neuronal firing patterns is the axon initial segment (AIS), where the local density of proteins and the morphology of the AIS in part determine the firing of neurons. We hypothesized that a disruption in the morphology and/or composition of the AIS can …

The Caspase Cascade During Hibernation In The Golden-Mantled Ground Squirrel, Spermophilus Lateralis, Michael David Treat

In several human pathologies like heart attack, stroke, neurodegenerative diseases, and autoimmune disorders, widespread cell death, or apoptosis, is a major cause of organ dysfunction and death. Hibernating golden-mantled ground squirrels, Spermophilus lateralis, experience numerous conditions during the winter that are known to be pro-apoptotic in other mammal systems (e.g. extreme hypothermia, ischemia and reperfusion, acidosis, increased reactive oxygen species, bone and muscle disuse). However, studies suggest that hibernators may invoke a protective phenotype to limit widespread cell damage and loss during the hibernation season. Could regulating apoptosis provide protection against the harmful conditions experienced during the hibernation season? Could …
Eye Repair In Xenopus Laevis, Cindy Xuan-Mai Kha
Eye Repair In Xenopus Laevis, Cindy Xuan-Mai Kha
UNLV Theses, Dissertations, Professional Papers, and Capstones
Eye development in vertebrates of complex steps that include specific interactions of the neuroectoderm and overlying head ectoderm. The African clawed frog, Xenopus laevis (X. laevis), has a well-characterize eye developmental pathway and is an established model for eye regeneration research. Additionally, Xenopus frogs have high regenerative abilities to regenerate individual eye tissues such as the retina, lens, and cornea. However, it was previously shown that the removal of the specified eye field during the neurulation stage or an eye during the swimming tadpole stage does not permit an eye to regenerate. Here we will describe a model for investigating …
Physiology And Genetics Of Starvation-Selected Drosophila Melanogaster, Christopher Michael Hardy
Physiology And Genetics Of Starvation-Selected Drosophila Melanogaster, Christopher Michael Hardy
UNLV Theses, Dissertations, Professional Papers, and Capstones
In nature, organisms have evolved to survive in stressful environments. This has driven organisms to adopt a wide range of unique adaptations. Investigating the mechanistic basis of these adaptations is an important tool for discovery that has led to major advances in science and medicine.
We study how organisms survive life without food, or starvational stress. Environmental stressors have shaped the quantity and quality of food sources across the globe. This has led to vast differences in the ability of some organisms to tolerate starvation over others. Many researchers have used Drosophila melanogaster as a model to study global patterns …

Efficient and effective analysis of the growing genomic databases requires the development of adequate computational tools. We introduce a fast method based on the suffix tree data structure for predicting novel targets of hypoxia-inducible factor 1 (HIF-1) from huge genome databases. The suffix tree data structure has two powerful applications here: one is to extract unknown patterns from multiple strings/sequences in linear time; the other is to search multiple strings/sequences using multiple patterns in linear time. Using 15 known HIF-1 target gene sequences as a training set, we extracted 105 common patterns that all occur in the 15 training genes …
