Paracellular transport of solutes and the control of the flow of molecules through the intracellular space in vertebrate epithelia is directed by tight junctions (TJs). Claudins form paracellular barriers and pores that determine tight junction permeability. This investigation attempts to explain the molecular bases for destruction and reconstruction of tight junctions within epithelial cells, occurring via both natural and disease-causing mechanisms. This interdisciplinary research is important in the advancement of our understanding of human biology and health, as different disruptions to epithelial tight junctions are hallmarks of many human diseases. The overall objective was to take previously made Claudin containing …
Fungicide Sensitivity Of Sclerotinia Sclerotiorum Isolates Selected From Five Different States That Use Different Fungicide Treatments, Cristian Wulkop Gil
Fungicide Sensitivity Of Sclerotinia Sclerotiorum Isolates Selected From Five Different States That Use Different Fungicide Treatments, Cristian Wulkop Gil
UCARE Research Products
Sclerotinia sclerotiorum is a plant pathogenic fungus that causes a disease called white mold that can infect more than 450 plant species including soybeans, dry beans, green beans, canola, and sunflower. This pathogen is capable of up to $252M in losses every year (U.S. Canola Association, 2014). Fungicides are widely used in developed agricultural systems to control disease. However, resistance to the most effective fungicides has emerged and spread in pathogen populations and there have been multiple reports of S. sclerotiorum isolates becoming resistant to certain fungicides. Since different fields in different states use different fungicide treatments on plants and …
Effects Of Lipid Activating Chemical Compounds On The Growth And Production Of Fatty Acids And Metabolites In Green Algae, David Nguyen, Nishikant Wase, Concetta Dirusso

This study examines the effects of small molecule lipid activating chemical compound, discovered from the high throughput screening (HTS) (2) methods of previous FATTT Lab studies on the growth and production of lipids and metabolites in microalgae. For this study, the effects of two lipid inducing chemical compounds from the HTS method were implemented with the microalgae strain Chlamydomonas reinhardtii CC-125. This experiment focused on scaling up to large amounts of culture, approximately 1L. These cultures were grown in specially designed large bioreactors that were able to accommodate for such large volume of algal culture. Algal cells were treated with …

T-helper 2 (Th2) cells function in the adaptive immune system to coordinate responses to large extracellular pathogens (Luckheerham, 2012). Th2 cells are one of the differentiated subtypes cells of CD4+ T cells. CD4+ T cells recognize foreign pathogens and differenitated in specialized subtypes to affectively destroy the pathogen (Luckheerham, 2012). Upon CD4+ T cell activation, the cells undergo metabolic reprogaming, resulting in a shift in metabolism (Almedia, 2016).
We have successfully created a Th2 metabolic network model. The Th2 metabolic network model contains 1151 genes, 2601 metabolites, and 4654 reactions.

Introduction: Antisense oligonucleotides (ASOs) are short chemically modified oligonucleotides (5-7.4 kDa) that can produce a pharmacological effect by binding to RNA and affecting intermediary metabolism. Over 35 phosphorothioate (PS) ASOs are at various stages of clinical development for use as therapeutic agents and pharmacological tools. Antisense therapy is a progressing area of research, as these small strands of nucleotide oligomers can be produced to silence genes that aggravate chronic disorders or infections. An important distinction for ASOs compared to DNA is the substitution of the phosphodiester (PO) backbone with the PS modification. This sulfur substitution allows for these polar polyanionic …

The purpose of this project is to purify and characterize the reaction kinetics of mutant versions the enzyme Proline Utilization A (PutA) in Sinorhizobium meliloti. The enzyme catalyzes the first step in proline metabolism. It has two active sites. The first is proline dehydrogenase (PRODH) which converts proline to pyrroline-5-carboxylate (P5C). The second is P5C dehydrogenase (P5CDH) which converts P5C to glutamate. Although many bacterial organisms have PutA, there are still significant interspecies variations, resulting in an entire family of PutA enzymes. The main difference is the length of the amino acid sequence. This affects the protein’s structure or …

Protein function elucidation often relies heavily on amino acid sequence analysis and other bioinformatics approaches. The reliance is further extended to structure homology modeling for ligand docking and protein-protein interaction mapping. However, sequence analysis of RPA3313 exposes a large, unannotated class of hypothetical proteins mostly from the Rhizobiales order. In the absence of sequence and structure information, further functional elucidation of this class of proteins has been significantly hindered. A high quality NMR structure of RPA3313 reveals that the protein forms a novel split βαβ fold with a conserved ligand binding pocket between the first β-strand and the N-terminus of …

I had the great privilege of working with Dr. Karin van Dijk, through UCARE, researching the specific pathways through which histone deacetylation occurs in plants during the 2015-2016 academic year. My first year conducting research helped me develop my technical skills and learn about experimental protocols and how to conduct them. I would like to continue my research during the 2016-2017 academic year and now that I have a year of research experience, be able to further develop my skills and learn more about my research project.
Background
Pseudomonas syringae is a bacterial pathogen that is well known for causing …

Hair Analysis In Motor Vehicles, Jaclyn E. Humrich, Larry Barksdale

The purpose of this research was to examine the frequency of human and animal hair in motor vehicles in the Lincoln, NE area. We were looking specifically at animal hair to see if there is a significant difference in the distribution of animal hair in pet-owner and non pet-owner vehicles. Finding a significantly high distribution of animal hair in pet-owner vehicles would lead us to believe that an association could be made between a suspect owning an animal and their presence at a crime scene.
Our null hypothesis is that there is no significance in the distribution of cat/dog hairs …
