Identification of Novel Regulatory Genes in Acetaminophen Induced Hepatocyte Toxicity by a Genome-Wide CRISPR/Cas9 Screen
(University of Missouri -- Kansas City, 2018)
Acetaminophen (APAP) is a commonly used analgesic responsible for over 56,000
overdose-related emergency room visits annually. A long asymptomatic period and limited
treatment options result in a high rate of liver ...
Structure/Function Analysis of Type IIa Receptor Tyrosine Phosphatases on Drosophila Muscle Integrity
(University of Missouri -- Kansas City, 2018)
The Lar-family of receptor protein tyrosine phosphatases (RPTPs); including
Lar, RPTPσ and RPTPδ, are utilized in signal transduction pathways during neural
development. Fundamentally, the processes of axon guidance ...
APP∙CNTN Complex Architecture is Conserved Throughout the Vertebrate Lineage
(2020)
Contactins (CNTNs) are a group of up to six cell adhesion molecules (CAMs) of the immunoglobulin (Ig) superfamily found throughout the metazoan lineage. CNTN architecture is broadly conserved, and these proteins are composed ...
Structure-Function Analysis of the Tribbles Pseudokinase
(2020)
Members of the Tribbles (Trb) family of pseudokinases have roles in development, cell cycle control, insulin signaling, and the immune response and have been linked to many human diseases. The structure of Drosophila ...
Investigation of functional domains of drosophilia tribbles protein in the insulin signaling pathway
(2020)
In this dissertation, I examined the function of the Drosophila melanogaster protein Tribbles (Trbl) within the insulin/insulin-like signaling (IIS) pathway. Trbl was initially discovered as a regulator of mitosis during ...
Non-genomic control of neuronal calcium signaling by the steroid hormone estrogen leads to neuroprotective effects
(2020)
It has been well documented that the onset of menopause correlates with an increase in the onset of neurodegenerative diseases such as Alzheimer’s disease. Estrogen supplementation was used as treatment/prevention for a ...
The herpes simplex virus virion host shutoff protein is targeted to mRNA cleavage sites through interactions with components of the host translational apparatus
(University of Missouri--Kansas City, 2011-01-20)
The virion host shutoff protein (Vhs) is a herpes simplex virus (HSV) protein involved in early shutoff of the host cell. It is a component of the infecting virion, located in the tegument region, that works by rapidly ...
3-Hydroxy-3-methylglutaryl-coenzyme A lyase: investigation of cysteines mediating intersubunit disulfide formation and regulation by thiol/disulfide exchange and discovery of an extramitochondrial homolog
(University of Missouri -- Kansas City, 2012-01-18)
3-Hydroxy-3-methylglutaryl-Coenzyme A lyase catalyzes the cleavage of 3-hydroxy-
3-methylglutaryl-Coenzyme A into acetoacetate and acetyl-Coenzyme A, a key reaction
in ketogenesis and leucine catabolism. Previous work ...
Structural and functional studies of type three secretion virulence factors from gram-negative pathogenic bacteria
(University of Missouri-Kansas City, 2011-12-21)
Many pathogenic Gram-negative bacteria utilize type III secretion systems (TTSS) to alter the normal functions of target host epithelial cells. Of the 1.1 million deaths that are caused by Shigella each year, nearly a third ...
A proteomic approach for studying LTR retrotransposon host factors in saccharomyces cerevisae
(University of Missouri--Kansas City, 2012-01-20)
The Ty retrotransposons of S. cerevisiae are mobile elements that resemble retroviruses, both in their genetic structures and replication cycles. Ty retrotransposition begins in the nucleus with the transcription of Ty ...
The expression and regulation on antimicrobial peptide genes in insects: studies in the tobacco hornworm manduca sexta
(University of Missouri--Kansas City, 2011-05-10)
Insects have evolved an efficient innate immune system to combat microbes. Most of our knowledge of insect immunity comes from studies with dipteran and lepidopteran insects, such as the fruit fly Drosophila melanogaster, ...
The role of drosophila protein kinase doubletime in circadian period determination, morning and evening oscillators and tauopathy
(University of Missouri--Kansas City, 2012-10-01)
In this dissertation, I used the GAL4-UAS binary expression method to overexpress mutant and wild type forms of the circadian protein kinase DBT in order to address several basic questions about DBT's biological functions. ...
Mutational and functional analyses of the dynein heavy chain indicate the existence of an apical-sistal transport cycle in cells
(University of Missouri--Kansas City, 2012-03-02)
The organization, survival, and function of eukaryotic cells depend on intracellular
transport governed by the microtubule based molecular motors cytoplasmic dynein and
kinesin. Dynein carries out the inward transport ...
Resveratrol Analogs: Potential Chemopreventive Agents in Breast Cancer
(2015-05-22)
Epidemiological data and studies in rodent models strongly support the role of
estrogens in the development of breast cancers. Estrogens have been added to the list of
known human carcinogens. Exact mechanisms underlying ...
HIV-1 gp120 and Methamphetamine-mediated Induction of Proinflammatory Cytokines/chemokines and Oxidative Stress in Astrocytes: Implications in Neuroinflammation
(2014-04-02)
HIV associated neurocognitive disorder (HAND) remains a major concern for patients infected with HIV. The viral envelope protein, gp120 has been extensively studied and some of its neurotoxic effects are due to the increased ...
Modulation of neuronal ryanodine receptor-mediated calcium signaling by calsenilin
(2013)
Calsenilin is calcium (Ca2+) ion Ca2+ binding protein found in the nucleus, plasma membrane, and endoplasmic reticulum of neuronal cells. Calsenilin was first found to interact with two proteins involved in early-onset ...
