Multivalent ligands hold promise for enhancing avidity and selectivity to simultaneously target multimeric proteins, as well as potentially modulating receptor signaling in pharmaceutical applications. Essential for these manipulations are nanosized scaffolds that precisely control ligand display patterns, which can be achieved by using polyproline oligo-helix macrocyclic nanoscaffolds via selective binding to protein oligomers and cell surface receptors. This work focuses on synthesis and structural characterization of different-sized polyproline tri-helix macrocyclic (PP3M) scaffolds. Through combined analysis of circular dichroism (CD), small- and wide-angle X-ray scattering (SWAXS), electron spin resonance (ESR) spectroscopy, and molecular modeling, a non-coplanar tri-helix loop structure with partially …

Hydrophobic Surface Patch Disruption To Produce Water-Soluble G-Protein Coupled Receptors, Christy Lynn Dyer

Electronic Theses and Dissertations Archive

G-Protein-Coupled Receptors (GPCR) are membrane protein receptors involved in most eukaryotic signaling processes. GPCR are the largest pharmaceutically relevant membrane protein group, serving as targets for approximately one-third of all drugs currently approved by the FDA and many drug candidates presently undergoing clinical trials. Still, only about one-fourth of all known GPCR are current pharmaceutical targets, leaving vast untapped potential. Chapter 1 describes the conserved structure of GPCR, and briefly introduces their diverse ligands and functions. The pharmaceutical relevance of GPCR is highlighted, along with some of the challenges associated with their structure determination that have hindered our understanding of …

Enhancing Antibody Responses By Multivalent Antigen Display On Thymus-Independent Dna Origami Scaffolds, Eike-Christian Wamhoff, James Brett Case, Shilpa Sanapala, Michael S Diamond, Et Al.

2020-Current year OA Pubs

Protein-based virus-like particles (P-VLPs) are commonly used to spatially organize antigens and enhance humoral immunity through multivalent antigen display. However, P-VLPs are thymus-dependent antigens that are themselves immunogenic and can induce B cell responses that may neutralize the platform. Here, we investigate thymus-independent DNA origami as an alternative material for multivalent antigen display using the receptor binding domain (RBD) of the SARS-CoV-2 spike protein, the primary target of neutralizing antibody responses. Sequential immunization of mice with DNA-based VLPs (DNA-VLPs) elicits protective neutralizing antibodies to SARS-CoV-2 in a manner that depends on the valency of the antigen displayed and on T …

On Modeling Arterial Blood Flow With Or Without Solute Transport And In Presence Of Atherosclerosis, Daniel N. Riahi, Saulo Orizaga

School of Mathematical & Statistical Sciences Faculty Publications

In this article, we review previous studies of modeling problems for blood flow with or without transport of a solute in a section of arterial blood flow and in the presence of atherosclerosis. Moreover, we review problems of bio-fluid dynamics within the field of biophysics. In most modeling cases, the presence of red blood cells in the plasma is taken into account either by using a two-phase flow approach, where blood plasma is considered as one phase and red blood cells are counted as another phase, or by using a variable viscosity formula that accounts for the amount of hematocrit …

The Role Of Vocal Development Patterns: Predicting Neurogenetic Risk In Infancy Using Early Vocal Development And Sex, Alyssa Cregg, Rachel Siela, Olivia Battaglia, Kaylee Bobay, Madison Chin, Athena Fordwor, Conghao Gao, Deeksha Handa, Erin Lee, Tiernan Mcdivitt, Grace Strabala, Victoria Tuell, Laurel Williams

The Journal of Purdue Undergraduate Research

Extant literature documents a higher rate of language/speech disorders in males; however, despite sex being a potential moderator of outcomes, we do not know what role it plays in early vocal behavior of infants at high risk for such disorders. The purpose of this study was to ask: (1) Do high-risk infants demonstrate atypical vocal development patterns? (2) Is the quality and quantity of early babble distinct for male and female infants, and does this pattern vary across risk? To answer these questions, we examined the canonical babbling ratio (CBR; the ratio of canonical syllables, those with a consonant and …

Genome-Wide Mutagenesis To Investigate The N-Terminal Methylome: The Protective Effects Of Hsp31 And Other Methylated Proteins In Yeast, James Rooney, Jacob Lindsey

The Journal of Purdue Undergraduate Research

The purpose of this study was to understand the role of methylation in regulating the cellular stress response of Hsp31 in Saccharomyces cerevisiae yeast cells. Hsp31 is known to be methylated by the N-terminal methyltransferase Tae1. Changing the methylation site can affect the methylation status of Hsp31, which may play a role in the protective activity of Hsp31 against cellular stress. GLO1 is a gene in yeast involved in catalyzing the detoxification of methylglyoxal (MGO), which is a by-product of glycolysis. We established that S. cerevisiae in the glo1Δ and background is sensitive to cellular stress by MGO. Mutant strains …

Machine Learning Of Big Data: A Gaussian Regression Model To Predict The Spatiotemporal Distribution Of Ground Ozone, Jerry Gu

The Journal of Purdue Undergraduate Research

Tracking pollution levels on the ground is important to the environment and public health. One of the pollutants of concern is ozone, which, at high concentrations, can cause respiratory and cardiovascular problems. The National Center for Atmospheric Research (NCAR) has published valuable ozone data obtained from ground-based sensors installed at selected locations. Because it is unfeasible to measure the exact ozone levels everywhere at any time, it would be valuable to predict the temporal-spatial distributions of ozone concentration based on existing data. This would help us better understand the patterns and trends in the data and make better decisions to …

A Computational Profile Of Invasive Lionfish In Belize: A New Insight On A Destructive Species, Joshua E. Balan

The Journal of Purdue Undergraduate Research

Since their discovery in the region in 2009, invasive Indonesian-native lionfish have been taking over the Belize Barrier Reef. As a result, populations of local species have dwindled as they are either eaten or outcompeted by the invaders. This has led to devastating losses ecologically and economically; massive industries in the local nations, such as fisheries and tourism, have suffered greatly. Attempting to combat this, local organizations, from nonprofits to ecotourism companies, have been manually spear-hunting them on scuba dives to cull the population. One such company, Reef Conservation Institute (ReefCI), operating out of Tom Owens Caye outside of Placencia, …

Parentally Exposed Zebrafish Larvae Have Altered Craniofacial Measurements: Multigeneration Developmental Atrazine Toxicity, Isabelle Akoro

The Journal of Purdue Undergraduate Research

Atrazine is a herbicide used throughout the midwestern United States to prevent broadleaf weeds in crops. The U.S. Environmental Protection Agency (EPA) has set the maximum contaminant level at 3 ppb (μg/L) in drinking water. Atrazine is an endocrine disrupter interfering with the function of hormones and disrupting normal physiology and homeostasis throughout development and the life course of an organism. The zebrafish model was used to test the hypothesis that an embryonic parental atrazine exposure will cause modifications in morphology in developing offspring. AB adult zebrafish were bred. Embryos were collected and exposed to atrazine concentrations of 0, 0.3, …
