Viral RNA structural equilibria and their interactions with host proteins
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Understanding viral RNA structure and how it functions is crucial in elucidating new drug targets. There are many kinds of viruses that utilize RNA ...
Advances in aptamer evolution and engineering
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Aptamers are single-stranded nucleic acids that fold into unique three-dimensional shapes that allow them to bind with high affinity and specificity ...
Ribozymes and aptamers in the RNA world, and in synthetic biology
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The RNA world hypothesis postulates that Ribonucleic Acids (RNA) may have provided functions of catalysis and genetic information storage during the ...
Discovery and characterization of regulatory mechanisms affecting the heteromeric acetyl-coenzyme a carboxylase in Arabidopsis
(University of Missouri--Columbia, 2016)
Fatty acid biosynthesis (FAS) is an essential metabolic pathway used by all organisms to generate fatty acids. A staple component of this pathway is the enzyme acetyl-CoA carboxylase (ACCase), which catalyzes the committed ...
Merging technology development of trapped ion mobility spectrometry quadrupole time-of-flight mass spectrometry with biological investigation of Medicago truncatularoot exudates
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] "New commercial ion mobility instrumentation has the potential to improve current analytical techniques, but developments need to be applicable to ...
In vitro characterization of Nudt16 orthologs by sequence and function provide evidence supporting a nuclear RNA degradation pathway
(University of Missouri--Columbia, 2009)
Nudt16, previously called X29, is known to be a metal-dependent decapping enzyme expressed in mammals and Xenopus . Nudt16 has been proposed to be the catalytic component of a previously unknown nuclear RNA degradation ...
Characterization of SF-hERR[beta] repression of human estrogen receptor alpha and estrogen receptor-beta transcriptional activities
(University of Missouri--Columbia, 2009)
Discovery of new ways to modulate estrogen actions through estrogen receptor is always exciting because of the importance of estrogen and ERs in many human diseases. In this dissertation, we report our discovery of the ...
Identification of novel breast carcinoma and melanoma avid peptides for imaging
(University of Missouri--Columbia, 2009)
During the last decade, peptides and their derivatives have been employed as effective cancer imaging agents. We aimed to identify new peptides probes specific for melanoma and breast carcinoma by phage display technology. ...
Signals affecting the urease status of plant-associated bacteria, Methylobacterium spp
(University of Missouri--Columbia, 2007)
Pink-Pigmented Facultative Methylotrophic bacteria (PPFMs, Methylobacterium spp.) have been found to be the most abundant microorganisms among phylloplane microflora, and have been recovered from all plants examined. I ...
Substrate activation in the urate oxidase reaction
(University of Missouri--Columbia, 2008)
The enzyme urate oxidase (UO) is involved in nitrogen metabolism of many organisms. Urate oxidation is carried out by UO without the aid of a metal ion or cofactor. A catalytic diad has previously been proposed to be ...
Phenotypic modulation of vascular smooth muscle cells : evidence for a role of the G protein-coupled P2y2 receptor
(University of Missouri--Columbia, 2008)
G protein-coupled receptors regulate two major functions of vascular smooth muscle cells (SMCs) - the vasomotor contractile response and the proliferative response. The contractile phenotype of SMCs has mainly been studied ...
A study of SecA : the motor of the bacterial secretion system by site-directed spin labeling and EPR
(University of Missouri--Columbia, 2008)
For more than 3 decades, the biochemical details of the Sec system of protein export have been teased out of Escherichia coli. Through these efforts we know that SecA, the ATPase of the Sec system, interacts with several ...
A custom oligonucleotide microarray analysis as a tool for dissecting soybean-bradyrhizobium japonicum nodule senescence
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean root nodules are symbiotic organs housing Bradyrhizobium japonicum, a soil bacterium that reduces atmospheric nitrogen to ammonium. The bacterium ...
Characterization and functional analysis of the P2Y₂R gene promoter
(University of Missouri--Columbia, 2006)
Extracellular nucleotides can bind to the P2Y₂R and modulate proliferation and migration of smooth muscle cells, which is known to be involved in intimal hyperplasia that accompanies atherosclerosis and post-angioplasty ...
Regulation of Nrf2 by a keap1-dependent E3 ubiquitin ligase
(University of Missouri--Columbia, 2007)
Oxidative damage to biological macromolecules has been implicated in diverse pathophysiological processes, including cancer, neurodegeneration, aging and cardiovascular disease. The Nrf2 transcription factor regulates ...
The role of P2Y₂ nucleotide receptors in vascular inflammation
(University of Missouri--Columbia, 2007)
Extracellular nucleotides act on P2 receptors to regulate vascular tone. Large amounts of extracellular nucleotides are released at the sites of tissue injury and may play an important role in the vascular inflammation. ...
