Independent Functions Of Clueless In Differential Integrin Secretion And Mitochondrial Quality Control In Drosophila Muscle
(2015)Drosophila Clueless (Clu) and its conserved orthologs are known for their role in the prevention of mitochondrial clustering. Here, we uncover its independent roles in the delivery of integrin subunits and the regulation ... -
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 ... -
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 ... -
Involvement of a specific ubiquitin ligase in the assembly of the dynein motor in the filamentous fungus Neurospora crassa
(University of Missouri--Kansas City, 2012-08-27)Eukaryotic cells utilize multiple molecular motor proteins to accomplish intracellular transport. The two microtubule based motors, kinesin and cytoplasmic dynein, work in concert to move cargoes outward and inward, ... -
Mating Type Specific Roles During The Sexual Cycle Of Phycomyces Blakesleeanus
(2014)Phycomyces blakesleeanus is a filamentous fungus that belongs in the order Mucorales. It can propagate through both sexual and asexual reproduction. The asexual structures of Phycomyces called sporangiophores have served ... -
Mechanism of Action of Nicotinamide Phosphoribosyltransferase Mediated Signaling in Oxidative Stress
(University of Missouri -- Kansas City, 2018)Worldwide there are an estimated 1 billion people that are affected by a form of neurodegenerative disease. The most common forms of neurodegenerative disease are Alzheimer’s disease and Parkinson’s disease, along ... -
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 ... -
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 ... -
Molecular mechanism, binding free energy, and sequence selectivity of intercalation of doxorubicin and DNA
(2021)Many drugs interact noncovalently with DNA either by groove binding or intercalation. Intercalation is a key process in drug discovery and biosensor development. Doxorubicin (DOX) is an intercalator drug that treats a wide ... -
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 ... -
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 ... -
Potential Mechanisms for Inhibition of Breast Cancer by Novel Azaresveratrol Analogs: Implications of Estrogen Receptor, Estrogen Metabolism and Cell Death Pathways
(2015-06-19)Prolonged exposure to estrogens has been implicated in the development of breast cancers. Steroidal estrogens have been implicated in the initiation and progression of cancer. Estrogens bind to their cognate estrogen ... -
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 ... -
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 ... -
Regulation of Antimicrobial Peptide Genes in the Tobacco Hornworm Manduca sexta
(2015-05-26)The innate immune system, also known as natural or non-specific immune system, is conserved from insects to humans. The insect innate immune system is composed of humoral and cellular components. Insect humoral responses ... -
Regulation of Gene Expression by Non-coding RNAs in Arabidopsis and Brachypodium
(2014)Expansion of high-throughput sequencing technology has increased our understanding in the importance of pervasive transcription and the resulting indispensable molecules, noncoding RNAs (ncRNAs). A significant effort has ... -
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 ... -
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. ... -
