Cocaine Use Disorder persists as a significant public health concern in the United States. Recent epidemiological data indicate that rates of cocaine-involved overdose deaths are rising, and treatment of Cocaine Use Disorder is challenging due to a lack of FDA-approved medications to help patients achieve abstinence and avoid relapse. Stress can precipitate cocaine craving and trigger relapse episodes, however the underlying neural circuitry by which stressors drive cocaine seeking is not completely understood. Our laboratory has recently identified the potential involvement of the rostrolateral aspect of the periaqueductal gray (rlPAG) in psychosocial stress-induced cocaine-seeking behavior using a rodent model of …

Annual Research Symposium
In regenerative dentistry, platelet rich plasma (PRP) has been used as a supra-physiological concentration of autologous growth factors capable of encouraging tissue regeneration. Despite this, there have been concerns raised about the use of anticoagulants, which are known to impair wound healing. In this work, a liquid formulation of platelet rich fibrin (PRF) called injectable-PRF (I-PRF) was studied without the need of anti-coagulants .

Can Mirna Be The Missing Link Between Parkinson’S Disease And Pesticides?, Fatma Gobba
Theses and Dissertations
Parkinson’s disease (PD) is a common neurodegenerative condition that leads to significant morbidity and a decline in the quality of life. It develops as a consequence of the loss of dopaminergic neurons in the substantia nigra pars compacta. Nevertheless, the development of PD is influenced by environmental factors, and the intricate nature of these relationships is further complicated by a multitude of factors, including the genetic backgrounds that are specific to populations and variations in environmental exposures, such as pesticides. Pesticides, consisting of a diverse family of chemicals commonly used in both agricultural and household settings to protect crops against …

Gene delivery to, and expression in, the mouse brain is important for understanding gene functions in brain development and disease, or testing gene therapies. Here, we describe an approach to express a transgene in the mouse brain in a cell-type-specific manner. We use stereotaxic injection of a transgene-expressing adeno-associated virus into the mouse brain via the intracerebroventricular route. We demonstrate stable and sustained expression of the transgene in neurons of adult mouse brain, using a reporter gene driven by a neuron-specific promoter. This approach represents a rapid, simple, and cost-effective method for global gene expression in the mouse brain, in …

BACKGROUND: Clinical, molecular, and genetic epidemiology studies displayed remarkable differences between ever- and never-smoking lung cancer. METHODS: We conducted a stratified multi-population (European, East Asian, and African descent) association study on 44,823 ever-smokers and 20,074 never-smokers to identify novel variants that were missed in the non-stratified analysis. Functional analysis including eQTL colocalization and DNA damage assays, and annotation studies were conducted to evaluate the functional roles of the variants. We further evaluated the impact of smoking quantity on lung cancer risk for the variants associated with ever-smoking lung cancer. RESULTS: Five novel independent loci, GABRA4, inter-genic region 12q24.33, LRRC4C, LINC01088, …

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship
Mutations in fused in sarcoma (fust-1) are linked to ALS. However, how these ALS causative mutations alter physiological processes and lead to the onset of ALS remains largely unknown. By obtaining humanized fust-1 ALS mutations via CRISPR-CAS9, we generated a C. elegans ALS model. Homozygous fust-1 ALS mutant and fust-1 deletion animals are viable in C. elegans. This allows us to better characterize the molecular mechanisms of fust-1-dependent responses. We found FUST-1 plays a role in regulating superoxide dismutase, glutamate signaling, and oxidative stress. FUST-1 suppresses SOD-1 and VGLUT/EAT-4 in the nervous system. FUST-1 also regulates synaptic AMPA-type glutamate receptor …
Employing A Machine Learning Approach In Precision Oncology To Predict Pik3ca Functional Status And Identify Phenocopying Variants Of Deleterious Pik3ca Mutations, Javier Castillo
CMC Senior Theses
The following proposal describes a modular machine learning approach that detects malfunctioning genes and pathways in cancer using the transcriptome of cancer patients. The transcriptome is underused in precision oncology and, combined with machine learning, can aid in the identification of hidden responders. Applied to the PI3K/AKT/mTOR pathway, this method can be used to predict PIK3CA functional status and identify phenocopying variants of deleterious PIK3CA mutations. The classifier will do this by integrating RNA-seq, copy number, and mutation data from tumors to determine the functional status of PIK3CA using a set of learned gene-specific weights. The classifier will then be …

NifA is a σ54 activator that turns on bacterial nitrogen fixation under reducing conditions and when fixed cellular nitrogen levels are low. The redox sensing mechanism in NifA is poorly understood. In α- and β-proteobacteria, redox sensing involves two pairs of Cys residues within and immediately following the protein’s central AAA+ domain. In this work, we examine if an additional Cys pair that is part of a C(X)5 C motif and located immediately upstream of the DNA binding domain of NifA from the α-proteobacterium Gluconacetobacter diazotrophicus (Gd) is involved in redox sensing. We hypothesize that the …

Extracellular Trna-Derived Rnas As Emerging Activators Of Endosomal Toll-Like Receptors: A Narrative Review, Justin Gumas, Yohei Kirino
Computational Medicine Center Faculty Papers
Background and Objective: The innate immune system deploys various pattern-recognition receptors (PRRs), including Toll-like receptors (TLRs), to detect the invasion of pathogens and initiate protective responses. TLR7 and TLR8 are located within the endosome of immune cells and are activated by single-stranded RNAs (ssRNAs). In addition to foreign ssRNAs from bacteria and viruses, endogenous self-ssRNAs, such as microRNAs (miRNAs), have been shown to activate TLR7 and TLR8, but such endogenous ssRNA ligands have not yet been fully elucidated. This scientific knowledge gap is partly derived from the technical limitations of standard RNA-seq, particularly its inability to capture non-miRNA-short non-coding RNAs …
Investigating The Role Of Endothelial Breast Cancer Susceptibility Gene 2 In Doxorubicin-Induced Cardiotoxicity, Berk U. Rasheed
Investigating The Role Of Endothelial Breast Cancer Susceptibility Gene 2 In Doxorubicin-Induced Cardiotoxicity, Berk U. Rasheed
Electronic Thesis and Dissertation Repository
Doxorubicin (Dox) is a chemotherapeutic drug used to treat various malignancies including breast and ovarian cancers. Accumulating evidence implicates cardiac impairments associated with Dox treatment. The Breast Cancer Susceptibility Gene 2 (BRCA2) functions to maintain genome-wide stability by promoting DNA-damage repair. Accordingly, cardiomyocyte damage is specifically regulated by contributors of DNA damage repair such as BRCA2. The endothelium, the innermost cells of every blood vessel, act to protect our tissues from noxious elements, however, recent evidence suggests that BRCA2 knockdown compromises endothelial cell function. A putative role of endothelial BRCA2 during Dox-induced cardiotoxicity (DIC) remains unknown. We hypothesized that endothelial-specific …

Proper wound closure requires the functional coordination of endothelial cells (ECs) and keratinocytes. In the late stages of wound healing, keratinocytes become activated and ECs promote the maturation of nascent blood vessels. In diabetes mellitus, decreased keratinocyte activation and impaired angiogenic action of ECs delay wound healing. Porcine urinary bladder matrix (UBM) improves the rate of wound healing, but the effect of exposure to UBM under diabetic conditions remains unclear. We hypothesized that keratinocytes and ECs isolated from both diabetic and non-diabetic donors would exhibit a similar transcriptome representative of the later stages of wound healing following incubation with UBM. …

The SARS-CoV-2 virus has evolved throughout the pandemic and is likely to continue evolving into new variants. Some of these variants may affect functional properties, including infectivity, interactions with host immunity, and disease severity. And compromised vaccine efficacy is an emerging concern with every new viral variant. Next-generation sequencing (NGS) has emerged as the tool of choice for discovering new variants and understanding the transmission dynamics of SARS-CoV-2. Deciphering the SARS-CoV-2 genome has enabled epidemiological survivance and forecast of altered etiologically. Clinical presentations of the infection are influenced by comorbidities such as age, immune status, diabetes, and the infecting variant. …

Orthologs Of The C. Elegans Heterochronic Genes Have Divergent Functions In C. Briggsae, Maria Ivanova, Eric G. Moss
Rowan-Virtua Research Day
The heterochronic genes of C. elegans comprise the best-studied pathway controlling the timing of tissue and organ formation in an animal. To begin to understand the evolution of this pathway, the significance of each factor, and the relationships among the components, we characterized 11 C. briggsae orthologs of C. elegans heterochronic genes. Using CRISPR/Cas9, we made a variety of alleles and found that several mutant phenotypes differ in significant ways from those of C. elegans. Although most orthologs displayed defects in developmental timing, those phenotypes could differ in which stages they controlled, the penetrance and expressivity of the phenotypes, or …

Differential Degeneration Of Neurons In A Mouse Model Of Canavan Disease, Vibha Chauhan, Quy Nguyen, Jeremy Francis, Paola Leone
Rowan-Virtua Research Day
Canavan disease (CD) is an inherited leukodystrophy caused by inactivating mutations to the glial enzyme aspartoacylase (ASPA). ASPA catabolizes neuronal N-acetylaspartate (NAA) into free acetate and aspartate and loss of this function results in the chronic elevation of non-catabolized NAA and the failure of developmental myelination. Elevated NAA is thought to cause damage to myelin and myelin-producing cells (oligodendrocytes, but the viability of neurons in CD is relatively unexplored. We compare here the progressive degeneration of neurons in two regions of the CD mouse brain, the thalamus and the cortex, distinguished by differing degrees of vacuolation, and show that the …

Utilizing Ultra-Performance Chromatography High-Resolution Mass Spectrometry To Investigate Fatty Acid Mediated Antibiotic Tolerance, Brittni Woodall
Doctoral Dissertations
The lipid membrane is the first component necessary to sustain life. To maintain homeostasis, segregate cellular machinery, provide protection from the environment, and reproduce, an organism must establish a boundary in which the processes can occur. Throughout the last two decades, research has propelled our knowledge of lipid membranes much beyond original hypotheses. Once thought of to be static and uniform, the understanding of the lipid membrane has evolved to encompass a structure that is responsive, unique, and intricately constructed by the organism itself. By chance or by choice, organisms adapt the lipid membrane according to the environment for which …

The Presence Of Childhood Obesity In Nebraska And The Physiological Repercussions Of The Disease, Madison R. Bezousek
Honors Theses
Childhood Obesity can cause lifelong repercussions in children and adults. There has been stigma around the causes of obesity and its relation to lifestyle choices, without consideration of the genetic and syndromic causes. In this literature review the causes of obesity were investigated, along with the effect on the physiological systems and the enviornmental factors that are continuing the obesity epidemic. Preventing and treating lifestyle obesity is something that is seen to have the greatest effect on youth, especially with intergenerational obesity. Nebraska schools have implemented programs to encourage healthy living, and ongoing research is being implemented to reduce the …

Nononcogenic somatic mutations are thought to be uncommon and inconsequential. To test this, we analyzed 43,693 National Heart, Lung and Blood Institute Trans-Omics for Precision Medicine blood whole genomes from 37 cohorts and identified 7131 non-missense somatic mutations that are recurrently mutated in at least 50 individuals. These recurrent non-missense somatic mutations (RNMSMs) are not clearly explained by other clonal phenomena such as clonal hematopoiesis. RNMSM prevalence increased with age, with an average 50-year-old having 27 RNMSMs. Inherited germline variation associated with RNMSM acquisition. These variants were found in genes involved in adaptive immune function, proinflammatory cytokine production, and lymphoid …

Anterior And Posterior Tongue Regions And Taste Papillae: Distinct Roles And Regulatory Mechanisms With An Emphasis On Hedgehog Signaling And Antagonism., Archana Kumari, Charlotte M. Mistretta
Anterior And Posterior Tongue Regions And Taste Papillae: Distinct Roles And Regulatory Mechanisms With An Emphasis On Hedgehog Signaling And Antagonism., Archana Kumari, Charlotte M. Mistretta
Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship
Sensory receptors across the entire tongue are engaged during eating. However, the tongue has distinctive regions with taste (fungiform and circumvallate) and non-taste (filiform) organs that are composed of specialized epithelia, connective tissues, and innervation. The tissue regions and papillae are adapted in form and function for taste and somatosensation associated with eating. It follows that homeostasis and regeneration of distinctive papillae and taste buds with particular functional roles require tailored molecular pathways. Nonetheless, in the chemosensory field, generalizations are often made between mechanisms that regulate anterior tongue fungiform and posterior circumvallate taste papillae, without a clear distinction that highlights …

PARP1 is a DNA-dependent ADP-Ribose transferase with ADP-ribosylation activity that is triggered by DNA breaks and non-B DNA structures to mediate their resolution. PARP1 was also recently identified as a component of the R-loop-associated protein-protein interaction network, suggesting a potential role for PARP1 in resolving this structure. R-loops are three-stranded nucleic acid structures that consist of a RNA-DNA hybrid and a displaced non-template DNA strand. R-loops are involved in crucial physiological processes but can also be a source of genome instability if persistently unresolved. In this study, we demonstrate that PARP1 binds R-loops in vitro and associates with R-loop formation …
Sperm Dna Integrity In Absolute Teratozoospermia Patients And Its Impact On Assisted Reproductive Technology Outcome, Dina Faris
Theses and Dissertations
Sperm DNA Fragmentation (SDF) is a common cause of male infertility, although it is underdiagnosed due to lack of routine testing. High levels of SDF are reported in men with abnormal sperm morphology. However, the implications of such findings on live birth following Intracytoplasmic Sperm Injection (ICSI) have not been studied in absolute teratozoospermia men (100% abnormal sperm morphology). In this prospective study, the severity of DNA damage was evaluated in absolute teratozoospermia patients and its impact on ICSI outcomes, particularly live birth rate. My study included 36 men with absolute teratozoospermia and 30 men with normal sperm. Real-time assessment …

Non-small cell lung cancer (NSCLC) is one of the most common types of cancer in the world and has a 5-year survival rate of ~20%. Immunotherapies have shown promising results leading to durable responses, however, they are only effective for a subset of patients. To determine the best therapeutic approach, a thorough and in-depth profiling of the tumour microenvironment (TME) is required. The TME is a complex network of cell types that form an interconnected network, promoting tumour cell initiation, growth and dissemination. The stroma, immune cells and endothelial cells that comprise the TME generate a plethora of cytotoxic or …
Effects That The Methylenetetrahydrofolate Gene Mutation (Both The C677t And A1298c Polymorphisms) Have On Both Men And Women’S Fertility Abilities And Subsequent Fetal Development, As Well As What Nutritional Changes Can Possibly Do To Aid In Reversing These Supposed Negative Effects., Elizabeth Simkanin
Williams Honors College, Honors Research Projects
This study discusses the perceived negative effects of variants (C677T and A1298C) of the methylenetetrahydrofolate (MTHFR) gene on male and female fertility and fetal development, as well as the potential for nutrition changes to aid in reversing these negative effects. This research project was completed in order to discuss the possible association with and connection between nutrition and fertility in both male and female individuals who have either of the two most common MTHFR gene polymorphisms, 677C>T and 1298A>C. These two polymorphisms are of particular interest because they are associated with the most decreased activity of the MTHFR …

A region on chromosome 21, the Down Syndrome critical region (DSCR), is associated with major defects found in Down Syndrome, such as craniofacial malformations. DYRK1A is a gene found on chromosome 21 within the DSCR that encodes an enzyme, dual specificity tyrosine-phosphorylation-regulated kinase 1A. DYRK1A is known to phosphorylate many substrate proteins and is thought to be involved in tumor suppression, neurological development, cell cycle regulation, and aging. Recently, the Litovchick lab and others reported that DYRK1A also plays a role in the double-strand break repair of DNA, which could lead to mutations and tumorigenesis, if deregulated.

Resistance to checkpoint-blockade treatments is a challenge in the clinic. Both primary and acquired resistance have become major obstacles, greatly limiting the long-lasting effects and wide application of blockade therapy. Many patients with metastatic melanoma eventually require further therapy. The absence of T-cell infiltration to the tumor site is a well-accepted contributor limiting immune checkpoint inhibitor efficacy. In this study, we combined intratumoral injection of plasmid IL-12 with electrotransfer and anti-PD-1 in metastatic B16F10 melanoma tumor model to increase tumor-infiltrating lymphocytes and improve therapeutic efficacy. We showed that effective anti-tumor responses required a subset of tumor-infiltrating CD8+ and CD4 …
