Ph Sensitivity Of Connexin 50 Hemichannels: H95 And Beyond, Leah Volk May 2018

Ph Sensitivity Of Connexin 50 Hemichannels: H95 And Beyond, Leah Volk

Biology Theses

Gap junction channels formed by connexin proteins are critical for the health and function of the vertebrate lens. It is important to understand how these channels are affected by pH because a pH gradient exists in lens tissue. Intracellular pH (pHi) is a regulator of gap junction coupling, and different connexins show different sensitivities to pHi. A “Particle-Receptor” model for pH-dependent channel closure involves the intramolecular interaction between the cytoplasmic tail of the connexin and a region near the mouth of the channel dependent on a highly conserved histidine residue at position 95. While this model …

Investigation Of Catalytic Activity Of Stable Β-Ketoacyl-Acp Substrate Analogs In Quorum Sensing Signal Synthesis, Nhu Lam May 2018

Investigation Of Catalytic Activity Of Stable Β-Ketoacyl-Acp Substrate Analogs In Quorum Sensing Signal Synthesis, Nhu Lam

Boise State University Theses and Dissertations

Quorum sensing is an intercellular mechanism used by many bacterial pathogens to regulate behaviors, such as motility, virulence, and antibiotic production. Disruption of quorum sensing is shown to be deleterious to bacterial pathogenicity, without causing lethality. In Gram-negative bacteria, acyl-homoserine lactone (AHL or acyl-HSL) signal molecules are synthesized by AHL synthase enzymes using acylated-acyl carrier protein (acyl-ACP) and S-adenosyl-L-methionine (SAM) as their substrates. Pantoea stewartii EsaI, which causes Stewart’s wilt in corn, and Yersinia pestis YspI, which causes bubonic plague are AHL synthases that use 3-oxohexanoyl-ACP and 3-oxooctanoyl-ACP as the acyl-substrate to synthesize 3-oxohexanoyl-HSL and 3-oxooctanoyl-HSL signals, respectively. Unfortunately, the …

Design Of Mononuclear Nonheme Enzyme For Oxygen Activation, Joel John Rempillo May 2018

Design Of Mononuclear Nonheme Enzyme For Oxygen Activation, Joel John Rempillo

Renée Crown University Honors Thesis Projects - All

Natural enzymes are complex systems with intricate folds and binding pockets, which recognize specific substrates and position them ideally for catalysis. Large size and complexity of enzymes prevent their study and use as industrial catalysts. On the other hand, de novo designed models of enzymes often use simple and stable protein scaffold, which streamlines mechanistic studies and allows industrial applications. In this work, we use previously designed four-helix bundle as a protein framework to incorporate 2-His-1- carboxylate motif often found in non-heme enzymes. Such coordination environment provides ligands to bind iron(II) and leaves three additional coordination sites to accommodate substrate …

Functional And Structural Impact Of The Loss Of The Leucine-Rich Repeat Protein Lrit1 In The Mouse Retina., Catherine Ann Cobb May 2018

Functional And Structural Impact Of The Loss Of The Leucine-Rich Repeat Protein Lrit1 In The Mouse Retina., Catherine Ann Cobb

Electronic Theses and Dissertations

Mutations in genes encoding the leucine-rich repeat (LRR) proteins nyctalopin and LRIT3 lead to complete congenital stationary night blindness because they are critical to depolarizing bipolar cell function in the retina. LRIT3 has two closely related family members, LRIT1 and LRIT2. In silico analyses of publicly available RNA-Seq data showed that Lrit1 was highly expressed in the retina. Here I describe the expression pattern and impact of loss of LRIT1 on retinal function. To enable these studies, we used CRISPR/Cas9 technology to create an Lrit1-/- mouse line. Retinal morphology and morphometry analyses showed no gross changes in retinal structure …

The Effects Of Passive Integrated Transponder Tagging On Cortisol Release In The Gulf Killifish, Fundulus Grandis, Ariel Marcelo Hernandez

Senior Honors Theses

Due to its ease of use, low cost, and essentially limitless number of unique codes, PIT tagging has become the favored technique for tagging individuals in biological studies. However, studies employing PIT tagging generally assume that stress due to the implantation and presence of a PIT tag has no influence on the experimental results. This study investigated the effects of PIT tagging on levels of the stress hormone cortisol in the Gulf Killifish, Fundulus grandis, an estuarine fish of the Gulf of Mexico that is prone to daily or seasonal environmental stressors. Cortisol was measured non-invasively by extracting and …

Binding Of Maize Necrotic Streak Virus (Mnesv) 3’ I-Shaped Structure (3’ Iss) To Eukaryotic Translation Factors (Eifs) And Implication In Eif4f Mediated Translation Initiation, Qiao Liu

Dissertations, Theses, and Capstone Projects

5' m7GpppN cap and the 3' poly adenosine (A) tail of eukaryotic mRNAs are key elements for recruiting translation initiation machinery in canonical translation initiation. Unlike host mRNAs, many viruses lack these elements and yet they are translated efficiently. Plant viruses, in particular, have complex structures within their untranslated regions (UTR) that allow them to bypass some cellular translation control steps. In Maize necrotic streak virus (MNeSV) 3' UTR, an I-Shaped RNA Structure (ISS) has been reported to mediate the virus translation initiation progress. 3’ ISS binding with eIF4F has been shown to facilitate translation. 5’ -3’ kissing …

Evidence For Organelle-Like Extracellular Vesicles From A Parasite Of Drosophila And Their Function In Suppressing Host Immunity, Mary Heavner

Dissertations, Theses, and Capstone Projects

Parasitic wasps act as keystone species in natural ecosystems. Adept at suppressing immunity of their insect hosts, these natural enemies of insect pests are used for biocontrol in many parts of the world. Female parasitic wasps of the closely-related species Leptopilina heterotoma (Lh), a generalist of many Drosophilia flies, and Leptopilina boulardi (Lb), a specialist on flies of the melanogaster subgroup, produce venom and virus-like particles (VLPs) in their long gland-reservoir complexes, a secretory organ connected to ovipositors. Venom and VLPs are deposited, along with wasp eggs, into the body of the wasp’s larval fly host …

Regulation Of The Tubulin Homolog Ftsz In Escherichia Coli, Monika S. Buczek May 2018

Regulation Of The Tubulin Homolog Ftsz In Escherichia Coli, Monika S. Buczek

Dissertations, Theses, and Capstone Projects

Escherichia coli is a well-known pathogen, and importantly, a widely used model organism in all fields of biological sciences for cloning, protein purification, and as a model for Gram-negative bacterial species. And yet, researchers do not fully understand how this bacterium replicates and divides. Every year additional division proteins are discovered, which adds complexity to how we understand E. coli undergoes cell division. Due to their specific roles in cytokinesis, some of these proteins may be potential targets for development of antibacterials or bacteriostatics, which are much needed for fighting the current global antibacterial deficit. My thesis work focuses on …

Functional Similarity Of Prd-Containing Virulence Regulators In Bacillus Anthracis, Malik Raynor May 2018

Functional Similarity Of Prd-Containing Virulence Regulators In Bacillus Anthracis, Malik Raynor

Dissertations and Theses (Open Access)

Bacillus anthracis produces three regulators, AtxA, AcpA, and AcpB, that control virulence gene expression and are members of an emerging class of regulators termed “PCVRs” (Phosphoenolpyruvate-dependent phosphotransferase regulation Domain-Containing Virulence Regulators). AtxA controls expression of the toxin genes; lef, cya, and pag, and is the master virulence regulator and archetype PCVR. AcpA and AcpB are less well studied. AcpA and AcpB independently positively control transcription of the capsule biosynthetic operon capBCADE, and culture conditions that enhance AtxA activity result in capBCADE transcription in strains lacking acpA and acpB. RNA-Seq was used to assess the regulons of the …

Nanoscale Organization Of The Small Gtpase Rac1, Kelsey Maxwell May 2018

Nanoscale Organization Of The Small Gtpase Rac1, Kelsey Maxwell

Dissertations and Theses (Open Access)

Rac1 is a small, guanine-nucleotide binding protein that cycles between an inactive GDP-bound and active GTP-bound state to regulate actin-mediated motility, migration, and adhesion. Plasma membrane (PM) localization is essential for its biological activity. Rac1 PM targeting is directed by a C-terminal membrane anchor that encompasses a geranylgeranyl-cysteine-methyl-ester, palmitoyl, and a polybasic domain (PBD) of contiguous lysine and arginine residues. Using high-resolution imaging combined with spatial mapping analysis, I found that Rac1 forms nanoclusters on the PM. Cycling between the GTP- and GDP-bound states, Rac1 forms nanoclusters that are non-overlapping, consequently undergoing guanine nucleotide-dependent spatial segregation. I further found that …

Engineering The Structure Of The Human Acidic Fibroblast Growth Factor To Enhance Its Stability And Cell Proliferation Activity, Julie Davis Eberle May 2018

Engineering The Structure Of The Human Acidic Fibroblast Growth Factor To Enhance Its Stability And Cell Proliferation Activity, Julie Davis Eberle

Graduate Theses and Dissertations

Human acidic fibroblast growth factor (hFGF1) is a protein well known for its role in cell growth and differentiation. To elicit these cell-signaling processes, hFGF1 non-selectively binds to any one of the seven cell surface hFGF receptor isoforms. Due to its significant involvement in tissue repair activity, hFGF1 is a prime candidate for novel wound healing therapeutics. However, one drawback toward its use as a novel wound healing therapeutic is the poor inherent thermal stability of hFGF1, as it has been found to unfold near physiological temperature. The cause of this instability is strong electrostatic repulsion created by a dense …

Optimizing Genetic Manipulation Of Methanogens Through Faster Cloning Techniques, Merrisa Jennings May 2018

Optimizing Genetic Manipulation Of Methanogens Through Faster Cloning Techniques, Merrisa Jennings

Biological and Agricultural Engineering Undergraduate Honors Theses

Methanogenesis is the biological production of methane. Only anaerobic archaea known as methanogens are capable of such a metabolic feat. They have strict living conditions and substrate sources which determine their rate of metabolism. This is of particular importance from a greenhouse gas reduction perspective or biogas capturing perspective. One of the best ways to optimize methanogen methane production is via genetic manipulation. The current procedures are timely though, therefore a faster cloning processes should be developed. The objective of this study was to optimize a premade genetic transformation kit known as the Gibson Kit. The Gibson Kit was supposed …

Evaluation Of Cafo Dairy Manure Treatment To Reduce Nutrient Transport, Jenna Laib Apr 2018

Evaluation Of Cafo Dairy Manure Treatment To Reduce Nutrient Transport, Jenna Laib

Honors Projects

Excess amounts of phosphorus and nitrogen flowing into Lake Erie from agricultural fields in Northwest Ohio has led to several harmful algal blooms (HABs). One potential source of those nutrients is manure applied to fields for fertilizer. Manure from confined animal feeding operations (CAFOs) is 95-98% water with only ~3% solids and nutrients, thus physical transportation is expensive relative to the value of the agricultural nutrients. Furthermore, once manure nutrients are applied to agricultural fields, they are relatively easily mobilized to waterways by precipitation. More than 800 lab-scale tests have been used to optimize the treatment of CAFO manure with …

Roles Of Phospholipases And Ribosomal S6 Kinase In Lipid Remodeling And Growth In Arabidopsis Response To Phosphate Deprivation, Yuan Su Apr 2018

Roles Of Phospholipases And Ribosomal S6 Kinase In Lipid Remodeling And Growth In Arabidopsis Response To Phosphate Deprivation, Yuan Su

Dissertations

Phosphate (Pi) is one of three macronutrients for plants, which is vital for plant growth and development. Understanding the mechanism by which plants respond and adapt to Pi deficiency not only unveils functions of genes and pathways involved, but also provides potential tools to manipulate crops to better stand Pi stress in low Pi-containing lands. One of the significant metabolic changes in plants under Pi starvation is the membrane lipid remodeling that converts Pi-containing lipids such as phospholipids to Pi-free lipids, such as glycolipids. To elucidate the metabolism and regulation of lipid remodeling, this dissertation characterizes the role of two …

Determining The Effects Of Quercetin On Cadmium Toxicity In Kidney Cells, Elizabeth Dugan Apr 2018

Determining The Effects Of Quercetin On Cadmium Toxicity In Kidney Cells, Elizabeth Dugan

Undergraduate Theses

Cadmium is a heavy transition metal that causes kidney disease via prolonged, low-level exposure due to circulating metallothioneins. These proteins transport cadmium ions to the proximal convoluted tubule, where they induce the creation of reactive oxygen species (ROS). Oxidative damage from ROS can lead to kidney dysfunction and eventually failure. Previous studies have shown that antioxidants, including quercetin, which is found in most fruits and vegetables, can lessen cadmium-induced toxicity. In this study, human embryonic kidney cells were pretreated for one hour with varying concentrations of quercetin ranging from 10 - 100 μM. This was followed by 24-hour treatment with …

A Cytotoxic Evaluation Of A Chalcone Derivative Library On A549 Cells, Mary Elaine Kuo Apr 2018

A Cytotoxic Evaluation Of A Chalcone Derivative Library On A549 Cells, Mary Elaine Kuo

Undergraduate Theses

Chalcones, a precursor to flavonoids, are chemical compounds found naturally in plants. The chalcones’ structure consists of a ketone bridge attached to two aromatic rings. Varying substituents on the aromatic rings allow for different affects, including anti-cancer properties. As a Michael acceptor, chalcones interact with pathways that cause inhibition of the initiation, promotion, and progression of cancer tumors. We have screened 32 compounds for growth inhibition in lung cells that vary the flexibility and confirmation of the 3 carbon bridge between the two aromatic rings as well as the effects of electronic modifications to the aromatic ring. We have found …
