Barrett, The Honors College Thesis/Creative Project Collection


Barrett, the Honors College accepts high performing, academically engaged students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project, supervised and defended in front of a faculty committee. The thesis or creative project allows students to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is a student’s opportunity to explore areas of academic interest with greater intensity than is possible in a single course. It is also an opportunity to engage with professors, nationally recognized in their fields and specifically interested and committed to working with honors students. This work provides tangible evidence of a student’s research, writing and creative skills to graduate schools and/or prospective employers.

Predicting the binding sites of proteins has historically relied on the determination of protein structural data. However, the ability to utilize binding data obtained from a simple assay and computationally make the same predictions using only sequence information would be more efficient, both in time and resources. The purpose of this study was to evaluate the effectiveness of an algorithm developed to predict regions of high-binding on proteins as it applies to determining the regions of interaction between binding partners. This approach was applied to tumor necrosis factor alpha (TNFα), its receptor TNFR2, programmed cell death protein-1 (PD-1), and one ...

Three populations of experimentally evolved Drosophila melanogaster populations made up of high temperature (H, constant 25 ᵒC), low temperature (C, constant 16 ᵒC) and temporal homogeneity (T, environment changes between 16 ᵒC and 25 ᵒC) were prepared and assayed to determine difference in citrate synthase activity. Between the three groups, the results were inconclusive: the resulting reaction rates in units of nmol min-1mgfly-1 were 81.8 + 20.6, 101 + 15.6, and 96.9 + 25.2 for the hot (H), cold (C), and temporally homogeneous (T) groups, respectively. We conclude that the high associated variability was due to a lack of control ...

The prrAB two-component system has been shown to be essential for viability in Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis. To study this system, several prrAB mutants of Mycobacterium smegmatis, a close relative of Mtb, were created for study. These mutants included a deletion mutant complemented with prrA from Mtb controlled by Pmyc1_tetO, a deletion mutant, and a deletion mutant complemented with prrAB from M. smegmatis controlled by the native prrAB promoter sequence (~167 bp upstream sequence of prrAB). In a previous study, the prrAB deletion mutant clumped excessively relative to the wild-type strain when cultured in a nitrogen-limited ...

The main objective of this project is to create a hydrogel based material system to capture and release CCRF-CEM Leukemia cancer cells via chemo-mechanical modulation. This system is composed of an aptamer-functionalized hydrogel thin film at the bottom of a microfluidic channel, which changes its film thickness as the temperature of the fluid in the system changes. The functionalized hydrogel film has been created as the primary steps to creating the microfluidic device that could capture and release leukemia cells by turning the temperature of the fluid and length of exposure. Circulating tumor cells have recently become a highly studied ...

This study was conducted to observe the effects of vitamin C supplementation upon the expression of sICAM-1 in asthmatic subject. Two groups were created, each with a sample size of 4 subjects. One group was the vitamin C group (VC) and the other was the placebo group (PL). The study was analyzed through observing concentrations of biomolecules present within samples of blood plasma and nasal lavages. These included vitamin C, sICAM-1 expression, and histamine. The following P-values calculated from the data collected from this study. The plasma vitamin C screening was p=0.3, and after 18 days of supplementation, p=0.03. For ...

Photosynthesis is a critical process that fixes the carbon utilized in cellular respiration. In higher plants, the immutans gene codes for a protein that is both involved in carotenoid biosynthesis and plastoquinol oxidation (Carol et al 1999, Josse et al 2003). This plastoquinol terminal oxidase (PTOX) is of great interest in understanding electron flow in the plastoquinol pool. In order to characterize this PTOX, polyclonal antibodies were developed. Expression of Synechococcus WH8102 PTOX in E. coli provided a useful means to harvest the protein required for antibody production. Once developed, the antibody was tested for limit of concentration, effectiveness in ...

As prices for fuel along with the demand for renewable resources grow, it becomes of paramount importance to develop new ways of obtaining the energy needed to carry out the tasks we face daily. Costs of production due to energy and time constraints impose severe limitations on what is viable. Biological systems, on the other hand, are innately efficient both in terms of time and energy by handling tasks at the molecular level. Utilizing this efficiency is at the core of this research. Proper manipulation of even common proteins can render complexes functionalized for specific tasks. In this case, the ...

The dopamine 2 receptor (D2R) is a Class A GPCR which is essential for signaling in the nervous system, and has been implicated in numerous illnesses. While there are over 50 currently approved drugs which act on D2R, the structure has never been determined in detail. Although crystallography has historically been difficult with GPCRs, in recent years many structures have been solved using lipidic cubic phase (LCP) crystallization techniques. Sample preparation for LCP crystallization typically requires optimization of genetic constructs, recombinant expression, and purification techniques in order to produce a sample with sufficient stability and homogeneity. This study compares several ...

G protein-coupled receptors, or GPCRs, are receptors located within the membrane of cells that elicit a wide array of cellular responses through their interactions with G proteins. Recent advances in the use of lipid cubic phase (LCP) for the crystallization of GPCRs, as well as increased knowledge of techniques to improve receptor stability, have led to a large increase in the number of available GPCR structures, despite historic difficulties. This project is focused on the histamine family of receptors, which are Class A GPCRs that are involved in the body’s allergic and inflammatory responses. In particular, the goal of this ...

Integrin is a protein in cells that manage cell adhesion. They are crucial to the biochemical functions of cells. L 2 is one type of integrin. Its I domain is responsible for ligand binding. Scientists understand how Alpha L I domain binds Mg2+ at a pH of 7 but not in acidic environments. Knowing the specificity of integrin at a lower pH is important because when tissues become inflamed, they release acidic compounds. We have cloned, expressed, and purified L I-domain and using NMR analysis, we determined that wild type Alpha L I domain does not bind to Mg2+ at ...
