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

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 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 ...
An Investigation into the Effects of Alterations in Ribosomal Proteins S4 and S5 on Translational Accuracy, Ribosomal RNA Processing, and Ribosome Assembly
(University of Missouri--Kansas City, 2016)
Accurate translation of genetic message is an essential step in gene expression and is carried out by the ribosome. Ribosomal proteins S4 and S5 are critical for the decoding and the assembly processes on the ribosome. The ...
Regulation of Antimicrobial Peptide Genes in Insects by the Toll Pathway and NF-kB Transcription Factors
(University of Missouri--Kansas City, 2017)
Insects lack adaptive immunity and solely rely on innate immunity to combat
pathogens. Innate immunity in dipteran and lepidopteran insects mainly depends on two
canonical pathways, the Toll pathway that provides ...
Structural Basis for the Regulation of the Ceramide Transfer Protein
(University of Missouri -- Kansas City, 2017)
Ceramide, a central intermediate in sphingolipid metabolism, is synthesized at the
endoplasmic reticulum (ER) and transferred to the Golgi by the ceramide transfer (CERT)
protein for conversion to sphingomyelin (SM). ...
Biochemical and Structural Studies of the Role of FKBP(L)s in the fly and Mammalian Circadian Cycle
(University of Missouri -- Kansas City, 2017)
FK506 binding-like proteins (FKBPLs) are proteins that structurally resemble the
immunophilins. Their functions in cell signaling include protein folding, molecular trafficking,
RNA splicing and cell cycle regulation ...
Hyper-Plastic Structural Evolution Of The PEX Domain - A Model Of Evolutionary Exaptation And Neofunctionalization At The Molecular Level
(University of Missouri--Kansas City, 2017)
With the advent of sophisticated genetic, biophysical and in silico technology an
enormous amount of information is being generated regarding the structural, biochemical and
physiological aspects of proteins. Tertiary ...
A Genetic Screen for Tribbles Suppressors Identifies the E3 Ubiquitin Ligase Neuralized as a Novel Target
(University of Missouri -- Kansas City, 2017)
In this dissertation, I used the Drosophila wing as a model tissue for a genetic screen
to identify novel targets of Tribbles. Drosophila Tribbles is the founding member of a family
of pseudokinases conserved between ...
Effect of TIMBD on Neurotoxicity Associated with HIV-1 Gp120 and Tat
(University of Missouri -- Kansas City, 2018)
Human Immunodeficiency Virus (HIV)-associated neurocognitive disorder (HAND)
is one of the undermining disorders that affects majority of HIV infected patients. Patients
with HAND suffer from both cognitive and motor ...
Modulation of calcium signaling through direct and indirect actions of polyphenolic phytostilbenes on neuronal calcium channels
(University of Missouri--Kansas City, 2017)
Today in the United States there are 6.5 million people affected by a
neurodegenerative disease. Recent findings hypothesize that calcium dyshomeostasis and
reactive oxygen species contribute to the progression of many ...
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 ...
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 ...
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 ...
