The copper ATPases : intracellular trafficking and nervous system function
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Copper is essential for life, as it participates as a cofactor in numerous enzymatic reactions including energy generation, antioxidant defense, ...
A novel role for the ATP7A copper transporter in cancer
(University of Missouri--Columbia, 2018)
membrane. Several key regions in the protein are required for its internalization and successful retrieval from the plasma membrane. Previous studies had shown that a single di-leucine motif in the cytoplasmic tail of ATP7A was required for its...
Aptamers that bind filovirus GP : a new frontier for detection and neutralization of Ebola and Marburg virus
(University of Missouri--Columbia, 2020)
Aptamers are single chained, nucleic acid-based affinity probes that bind to their targets with strong affinity and specificity. They are made through an in vitro combinatorial selection method, wherein large libraries of ...
Biophysical characterization of the structure and flexibility of the E. Coli ribosome
(University of Missouri--Columbia, 2019)
have an internal cavity that is divided into three sites, named A, P, or E site. The bacterial ribosome has a 30S small subunit, which consists of a 16S rRNA and 21 attached proteins, and a 50S large subunit that is made up of the 23S rRNA, 5S r...
Targeted cancer radioimaging and radiotherapy and the development of tumor-avid molecules using phage display
(University of Missouri--Columbia, 2021)
Prostate cancer (PCa) is the second leading cause of cancer death in men and new biomarkers are needed to improve diagnostic and therapeutic approaches in aggressive forms of this disease. CD44v6, a splice variant of the ...
Skeletal muscle weakness and mitochondrial dysfunction in the osteogenesis imperfecta murine (oim) model
(University of Missouri--Columbia, 2021)
Osteogenesis imperfecta (OI), also commonly referred to as brittle bone disease, is a heritable connective tissue disorder occurring in roughly 1:15,000 births. OI arises as a result of mutations in the type I collagen ...
HIV-1 5'UTR RNA structures: connections to infectious lifecycle and potential therapeutic applications
(University of Missouri--Columbia, 2021)
Human immunodeficiency virus (HIV) is among the most sinister pathogens plaguing man. As of now, we do not yet have a method to "cure" infection once the virus has integrated into the host genome. It has the highest mutation ...
Bacteriophage display selections of ovarian cancer avid peptides
(University of Missouri--Columbia, 2014)
GABP regulation of the murine GABPa/ATPsynthase coupling factor six and human glutathione reductase promoters
(University of Missouri--Columbia, 2005)
GABPa is expressed from a bi-directional promoter expressing ATP synthase coupling factor six (CF6) in the opposite direction. This bi-directional promoter is regulated by GABP, indicating an autoregulation of GABPa. GABP ...
Informatically-informed biochemical characterization of aptamer-protein complexes
(University of Missouri--Columbia, 2022)
Nucleic acid aptamers are single-stranded oligonucleotides that fold into unique three-dimensional shapes that typically bind to targets of interest with high specificity and high affinity. However, a significant limiting ...
Discovery of epitopes governing MMP-12 specificity for fibrillar substrates : BINDSIght, a method for determining specific sites of substrate surface interactions
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] What determines MMP-12 elastase activity? We have found that the fibrillar substrate specificity of MMP-12 involves surfaces ranging beyond the ...
Characterization of peptides and phage that bind galectin-3 selected from bacteriophage display libraries: a study of the role of galectin-3 in metastasis-associated cancer cell adhesion
(University of Missouri--Columbia, 2005)
identified peptide antagonists of galectin-3 using combinatorial bacteriophage (phage) display technology. The peptides bound with high affinity to purified galectin-3 protein and to cell surface galectin-3. Experiments with a series of recombinant serially...
RNA structural studies : implications in HIV-1 replication and the origins of life
(University of Missouri--Columbia, 2021)
Structure and function relationships are important to understand many biological processes. Biological components are not one dimensional and their structures may drive key aspects of their function. This dissertation ...
The role of the P2Y₂ nucleotide receptor in inflammation: the mechanisms of P2Y₂ receptor-mediated activation of G proteins
(University of Missouri--Columbia, 2007)
The extracellular ATP/UTP receptor, i.e., the P2Y₂ receptor (P2Y₂R), mediates pro-inflammatory responses in the vasculature, including the endothelium-dependent infiltration of monocytes and their transmigration into sites ...
Regulation of ethylene biosynthesis by mitogen-activated protein kinase cascades in Arabidopsis
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Ethylene (C[subscript2]H[subscript 4]), a simple gaseous hydrocarbon, is an important plant hormone that has profound effects on plant growth, ...
Glomerular deposition of homotrimeric type I collagen in the COL1A2 deficient mouse
(University of Missouri--Columbia, 2006)
Type I collagen is the most abundant structural protein in the body. Type I collagen generally exists as a heterotrimeric protein; however, a homotrimeric isotype of type I collagen has been identified. Our lab currently ...
Roles of dynamin-related protein network in plant immune responses and development
