Role Of Pu.1 And C/Ebpα In Remodelling The Interleukin (Il)-1Β Enhancer-Promoter Interaction, Woohyun Cho, Soon-Duck Ha, Sung Ouk Kim
Western Research Forum
Background: IL-1b is a potent inflammatory cytokine promptly expressed in activated myeloid immune cells. Among various transcription factors, PU.1 and CCAAT/enhancer-binding protein alpha (C/EBPa) play a key role in the lineage commitment of myeloid cells. To date, however, the exact mechanisms by which these lineage-determining transcription factors employ to regulate the expression of myeloid-specific genes remains elusive; thus, this study explores the role of PU.1 and C/EBPa in remodelling the chromatin conformation that allows ample production of IL-1b.
Methods: To examine the mechanism of these lineage-determining transcription factors, production of IL-1b and enhancer-promoter interactions were analyzed in non-myeloid B16-BL6 cells …

Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, Jonathan Korbitz
UNO Student Research and Creative Activity Fair
Abstract:
The northern long-eared bat (Myotis septentrionalis) is one of many species of hibernating bats in North America affected by a recently discovered fungal disease called white-nose syndrome (WNS). Northern long-eared bats seem to be extremely susceptible to the disease with mass fatalities occurring among populations in eastern North America. Researchers in the eastern distribution of this species have performed mtDNA analysis to identify the population structure of the species; however, genetic analysis has yet to be done in western parts of its distribution. The goal of this study is to create a better understanding of the genetic …

Long non-coding RNAs (lncRNAs) were once thought not to have useful functions in organisms but rather to be products of aberrant transcription. However, roles are being found for lncRNAs in beneficial processes such as controlling gene expression. In some of these cases, lncRNAs form R-loops in vivo. R-loops are nucleic acid structures consisting of hybridized strands of single-stranded DNA (ssDNA) and single-stranded RNA (ssRNA) as well as the displaced strand of ssDNA. Formation of these R-loops is important for gene regulation by the lncRNAs. However, factors that promote formation of lncRNA R-loops are not known. The gene PHO84 is being …

Fret Biosensors: Engineering Fluorescent Proteins As Biological Tools For Studying Parkinson’S Disease, Nathan J. Leroy, Jacob R. Norley, Saranya Radhakrishnan, Mathew Tantama
The Summer Undergraduate Research Fellowship (SURF) Symposium
Parkinson’s Disease (PD) is a common neurodegenerative disease with over 200,000 new cases each year. In general, the cause of the disease is unknown, but oxidative stress inside of neurons has been associated with the disease’s pathology for some time. Currently, techniques to study the onset of PD inside of neurons are limited. This makes treatments and causes difficult to discover. One solution to this has been fluorescent protein biosensors. In short, these proteins can be engineered to glow when a certain state is achieved inside a cell. The present research discusses the engineering of a genetically-encoded fluorescent protein (FP) …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Purinergic signaling is a type of extracellular communication that occurs between cells, mediated by adenosine triphosphate (ATP), adenosine diphosphate (ADP), and adenosine. In Parkinson’s Disease, purinergic signaling is disrupted, which contributes to neurodegeneration. In order to monitor this change in cell-to-cell signaling, there is a need for the development of a fluorescent protein (FP) biosensor to study the changes in the concentration of the signaling molecule ATP and its decomposition bioproduct ADP. This summer a genetically encoded ADP sensor that measures changes in ADP concentration was developed. This sensor utilizes Forster Resonance Energy Transfer (FRET) which is a sensing technique …

Celiac Disease is a hypersensitive response to gluten caused by HLA-DQ2 or HLA-DQ8 T-cell presentation, initiating destruction of intestinal epithelial cells. Currently, the only remedy for those suffering from celiac disease is elimination of all gluten from the diet. Studies indicate that an indigestible fragment of the gluten molecule, alpha-gliadin subcomponent 33-mer, rich in proline and glutamine, is responsible for the hypersensitivity response. Determination of 33-mer concentration in wheat lines could be beneficial to future development of wheat lines with reduced 33-mer concentration. Protein from wheat flour was extracted and subjected to ELISA techniques in order to quantify the concentration …

Molecular Regulation Of Stem Cell Behavior During Tissue Repair And Cancer Formation, Nestor J. Oviedo
Molecular Regulation Of Stem Cell Behavior During Tissue Repair And Cancer Formation, Nestor J. Oviedo
Science Seminar Series
Oviedo will be presenting his work on identifying the mechanisms of adult stem cell fate determination based on their topographical location in the adult body. Understanding stem cell fate determination is crucial because tissue repair and neoplastic growth are greater in anterior than in posterior regions of adult animals. Despite its critical implications for stem cell biology, carcinogenesis and regenerative medicine, this physiological phenomenon has remained overlooked. Recent findings from his group provide intriguing evidence implying DNA repair mechanisms and cellular signaling through post-translational modifications regulate stem cell fate decision depending on their topographical location in the adult body. We …

Pt-Mal-Lhrh Mediates Breast Cancer Cell Cytotoxicity Through Increased Apoptosis, Kendall E. Collins
Posters-at-the-Capitol
In the United States one in eight women will be afflicted with breast cancer. It is estimated that in 2016 there will be approximately 246,600 new invasive breast cancer cases and 61,000 new non-invasive cases. Triple negative breast cancers account for 15% of all breast cancers and are significantly more aggressive than other subtypes. Treatment options for triple negative breast cancer are limited due to the cancers not expressing the estrogen, progestogen, or herceptin receptors making them unresponsive to hormonal therapy. Our recent work centers around developing a novel chemotherapeutic agent that will direct therapy selectively to triple negative (4T1) …

Design Of Novel Ion Channel Modulators, Vladimir Yarov-Yarovoy
Science Seminar Series
Function and modulation of neuronal sodium channels are critical for the neuromodulation of electrical excitability and synaptic transmission in neurons - the basis for many aspects of signal transduction, learning, memory and physiological regulation. Mutations in neuronal voltage-gated sodium channel genes are responsible for various human neurological disorders. Furthermore, human neuronal voltage-gated sodium channels are primary targets of therapeutic drugs used as local anesthetics and for treatment of neurological and cardiac disorders. Yarov-Yarovoy's lab is working on rational design of novel therapeutically useful blockers of voltage-gated sodium channels for treatment of pain and epilepsy. Serious, chronic pain affects at least …

Design And Development Of A Plasmid Vector For Protein Expression And Purification, Mahima Grover, Craig Sweet, David H. Thompson
The Summer Undergraduate Research Fellowship (SURF) Symposium
Production and isolation of proteins are difficult, costly and time-consuming processes. The aim of this project is for the development of plasmids, which allow for streamlined production and isolation of proteins. To allow for modular insertion of varying segments of DNA we are using ‘recursive directional ligation by plasmid reconstruction’. This technique uses type II restriction endonucleases, which cut downstream from their recognition site allowing multiple insertions without losing a restriction site. Using this process, we can ligate multiple DNA sequences together and express them to be able to construct a scar less fusion protein. In order to accomplish this, …

Purification, Optimization, And Growth Of New Delhi Metallo-Β-Lactamase-1 Protein Crystals Mixed With Nz218 Inhibitor, Brandon M. Wills
Celebration of Learning
New Delhi metallo-β-lactamase-1 is a problematic gene found in certain strains of bacteria that cause them to become antibiotic resistant to nearly all known antibiotics. While some antibiotics are available to treat patients with a bacterial infection, most are toxic or do not have 100% success rates. With that being said, it is imperative that we search for a molecule that is successfully able to inhibit the effects of this gene every time. Such a discovery would help tremendously with new antibiotic drug development and also prevent further damage by these dangerous bacteria. In this presentation, I will describe the …

Creative Activity and Research Day - CARD
Human Cytomegalovirus (HCMV) is a herpesvirus that infects a majority of the world’s population. There are many viral gene products that aid in virus infection and the establishment of the lifelong latency. UL111A, is a viral gene which, through alternate intron splicing, codes for two protein products cmvIL-10 and LAcmvIL-10 that mimic the structure of human interleukin-10 (hIL-10) to varying degrees. cmvIL-10 has been shown to have a wide range of physiological effects, whereas the effects of LAcmvIL-10 appear to be much more limited in scope. This study seeks to measure the expression levels of LAcmvIL-10 during lytic infection of …

Doxycycline Resistance In Plasmodium Falciparum Linked To Single Nucleotide Polymorphisms In The Plasmodium Falciparum Apicoplast Small Subunit Ribosomal Rna (Pfssrrna) Gene, Amanda Wasko
Scholarly and Creative Works Conference (2015 - 2021)
Plasmodium falciparum, a protozoan parasite known as malaria, widely impacts human health; thus antimalarial drug investigations are critical. Doxycycline is a commonly used antimalarial prophylactic, but its mechanism of action is unclear. In prokaryotes, doxycycline works as an antibacterial by disrupting protein translation via the small subunit ribosome. Interestingly, P. falciparum has a small subunit ribosome of prokaryotic origins in the apicoplast, a plastid-like organelle. Therefore, we hypothesized that doxycycline works in P. falciparum by inhibiting protein synthesis via the small subunit ribosomal RNA and that mutations in the gene encoding the P. falciparum apicoplast small subunit ribosomal RNA …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Parkinson’s disease is a neurodegenerative disease involving the death of neurons in the substantia nigra and loss of the neurotransmitter, dopamine. The disease leads to progressive loss of motor control. Exact causes and mechanisms by which Parkinson’s disease proceeds are unknown, however, previous experiments determine oxidative stress in mitochondria as a factor that results in cell death. Strategies have been implemented to generate fluorescent biosensors to monitor reactive oxygen species (ROS) concentrations while simultaneously measuring the spatiotemporal distribution and correlation between the ROS, cellular function and organelle. Orp1, an enzyme found in yeast, is a sensitive oxidizing species and when …

Elucidating The Role Of Hausp Ubiquitin Like Domains In The Catalytic Function Of Usp7, Anuj Patel, Nicole Davis, Andrew Mesecar
The Summer Undergraduate Research Fellowship (SURF) Symposium
Ubiquitin specific proteases (USPs) are a class of enzymes involved in myriad cellular processes. One USP of great interest due to its oncogenic properties is USP7. In normal conditions USP7 is closely regulated due to its responsibility for destabilizing the tumor suppressor, p53, through the deubiquitination of MDM2. In multiple myeloma cases, it appears the regulation of USP7 subsides, as it is largely overexpressed, leading to the inappropriate degradation of p53. Inhibition of USP7 could, therefore, prove a viable target for cancer therapy. A greater understanding of USP7’s function and structure can lead to more insight into how this enzyme …
