Apaview: A Web-Based Platform For Alternative Polyadenylation Analyses In Hematological Cancers, Xi Hu, Jialin Song, Jacqueline Chyr, Jinping Wan, Xiaoyan Wang, Jianqiang Du, Junbo Duan, Huqin Zhang, Xiaobo Zhou, Xiaoming Wu

Faculty, Staff and Student Publications

Background: Hematologic malignancies, such as acute promyelocytic leukemia (APL) and acute myeloid leukemia (AML), are cancers that start in blood-forming tissues and can affect the blood, bone marrow, and lymph nodes. They are often caused by genetic and molecular alterations such as mutations and gene expression changes. Alternative polyadenylation (APA) is a post-transcriptional process that regulates gene expression, and dysregulation of APA contributes to hematological malignancies. RNA-sequencing-based bioinformatic methods can identify APA sites and quantify APA usages as molecular indexes to study APA roles in disease development, diagnosis, and treatment. Unfortunately, APA data pre-processing, analysis, and visualization are time-consuming, inconsistent, …

Monitoring The Systemic Immune System To Understand And Improve The Efficacy Of Immunotherapy For Metastatic Osteosarcoma, Justin Edward Markel

Graduate Theses, Dissertations, and Problem Reports (ETD)

Osteosarcoma (OS) is a complex tumor with no effective targeted therapies due to its genomic heterogeneity and pleomorphism. The immune response it creates, particularly against metastatic lesions, is considerable; however, various suppressive mechanisms induced by the tumor prohibit its effectiveness. The presence of infiltrating lymphocytes suggests that therapeutic disinhibition through checkpoint blockade could increase antitumor immunity, though none have been successful in clinical trials. The complexities of the immune response to OS tumors have yet to be unraveled; however, there is evidence to suggest that cell-mediated immunity (CMI, specifically T cells, Natural Killer [NK] cells, and myeloid-lineage cells [MLCs]) plays …

A Case Of Irritable Bowel Syndrome In The Setting Of Generalized Anxiety Disorder, Stephen Driscoll

Capstone Showcase

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterized by a relapsing-remitting course of abdominal discomfort and change in stool form and/or frequency in the absence of any structural or biochemical abnormalities. Currently there is debate on its pathogenesis but there is no definitive conclusion. Treatment consists of primarily playing symptomalogic catch-up with anti-spasmodics, anti-diarrheals, stool softeners, or laxatives depending on which symptoms the patient is currently experiencing. Patients with IBS typically struggle to control their symptoms long term, like the patient described in this case study. This case study explores a possible link between IBS and its’ most …

Treatment Of Hypothyroidism: Desiccated Thyroid Extract, Aimee Fong

Capstone Showcase

The treatment of hypothyroidism with Levothyroxine (T4) has been well studied and FDA approved. However, many patients continue to have signs and symptoms of hypothyroidism while on Levothyroxine treatment despite reaching appropriate thyroid levels. An additional thyroid treatment known as desiccated thyroid extract (DTE) is made from dried pig thyroid glands and is advertised as a “natural” alternative to Levothyroxine. Despite lack of FDA approval and studies surrounding DTE, clinicians have prescribed DTE to patients, many of whom reported relief of their symptoms. The following poster highlights the approach to the treatment of hypothyroidism with Levothyroxine and DTE and outlines …

Antibiotics May Be Unnecessary In The Treatment Of Acute Uncomplicated Diverticulitis, Madison Gump

Capstone Showcase

Acute diverticulitis is one of the most common gastrointestinal diseases worldwide and is increasing in prevalence. Symptoms include abdominal pain, fever, changes in bowel habits, nausea, and vomiting. Traditionally, this disease has been treated with antibiotics, but new research has emerged that has provided evidence that it may be safe to treat acute uncomplicated cases without antibiotics. This represents an area of medicine where it may be possible to reduce the use of unnecessary antibiotics and, therefore, contribution to bacterial antibiotic resistance. The current research studies do have some limitations and future studies with larger, more diverse patient populations and …

Further Decoding The Molecular Relationship Between Pancreatic Adenocarcinoma And Diabetes Mellitus, Russell H. Moreland Iii, Sheema Khan

MEDI 9331 Scholarly Activities Clinical Years

Pancreatic ductal adenocarcinoma (PDAC) is a devastating malignancy, especially as there are no current reliable methods of screening. Recently literature reports a significant relationship with pancreatic ductal adenocarcinoma and diabetes mellitus (DM). The pathologic molecular mechanism is not completely understood but it may hold insights into the development of novel screening and treatment options. In our study we compiled a list of 74 proteins involved in the PDAC and DM pathway, with 47 showing increased expression levels and 11 with decreased expression levels. These proteins are currently undergoing further computational analysis to identify their pathway interactions.

Dose Accumulation For Mr-Guided Adaptive Radiotherapy: From Practical Considerations To State-Of-The-Art Clinical Implementation, Brigid A Mcdonald, Cornel Zachiu, John Christodouleas, Mohamed A Naser, Mark Ruschin, Jan-Jakob Sonke, Daniela Thorwarth, Daniel Létourneau, Neelam Tyagi, Tony Tadic, Jinzhong Yang, X Allen Li, Uffe Bernchou, Daniel E Hyer, Jeffrey E Snyder, Edyta Bubula-Rehm, Clifton D Fuller, Kristy K Brock

Faculty, Staff and Student Publications

MRI-linear accelerator (MR-linac) devices have been introduced into clinical practice in recent years and have enabled MR-guided adaptive radiation therapy (MRgART). However, by accounting for anatomical changes throughout radiation therapy (RT) and delivering different treatment plans at each fraction, adaptive radiation therapy (ART) highlights several challenges in terms of calculating the total delivered dose. Dose accumulation strategies-which typically involve deformable image registration between planning images, deformable dose mapping, and voxel-wise dose summation-can be employed for ART to estimate the delivered dose. In MRgART, plan adaptation on MRI instead of CT necessitates additional considerations in the dose accumulation process because MRI …

Faculty, Staff and Student Publications

Obesity is a common chronic disorder and has detrimental long-term consequences if left untreated. Herein, we report a case of a young lady who suffered from morbid obesity and many of its consequences, and we present a literature review of these complications. While the cause of obesity is multifactorial, the genetic component is particularly important in the pathophysiology of marked obesity. Resistance to Leptin is considered one of the main causes of obesity. There is a unique relationship between polycystic ovary syndrome and obesity, as observed in our case. Obesity is associated with cardiovascular and lung diseases such as heart …

Faculty, Staff and Student Publications

Background. For men with intermediate-risk prostate cancer (IRPC), adding short-term androgen deprivation therapy (ADT) to external beam radiation therapy (EBRT) has shown efficacy, but men are often reluctant to accept it because of its impact on quality of life. Methods. We conducted time tradeoffs (score of 1 = perfect health and 0 = death) and probability tradeoffs with patients aged 51 to 78 y who had received EBRT for IRPC within the past 2 y. Of 40 patients, 20 had received 6 mo of ADT and 20 had declined. Utility assessments explored 4 ADT-related side effects: hot flashes, fatigue, loss …

Predicting Clinical Response To Everolimus In Er+ Breast Cancers Using Machine-Learning, Aritro Nath, Patrick A Cosgrove, Jeffrey T Chang, Andrea H Bild

Faculty, Staff and Student Publications

Endocrine therapy remains the primary treatment choice for ER+ breast cancers. However, most advanced ER+ breast cancers ultimately develop resistance to endocrine. This acquired resistance to endocrine therapy is often driven by the activation of the PI3K/AKT/mTOR signaling pathway. Everolimus, a drug that targets and inhibits the mTOR complex has been shown to improve clinical outcomes in metastatic ER+ breast cancers. However, there are no biomarkers currently available to guide the use of everolimus in the clinic for progressive patients, where multiple therapeutic options are available. Here, we utilized gene expression signatures from 9 ER+ breast cancer cell lines and …

A Transgenic Bacterial Artificial Chromosome Approach To Identify Regulatory Regions That Direct Amhr2 And Osterix Expression In Müllerian Duct Mesenchyme, Malcolm M Moses, Rachel D Mullen, Daniel I Idowu, Peter Maye, Soazik P Jamin, Richard R Behringer

Faculty, Staff and Student Publications

A transgenic mouse approach using bacterial artificial chromosomes (BAC) was used to identify regulatory regions that direct Müllerian duct expression for Amhr2 and Osterix (Osx, also known as Sp7). Amhr2 encodes the receptor that mediates anti-Müllerian hormone (AMH) signaling for Müllerian duct regression in male embryos. Amhr2 is expressed in the Müllerian duct mesenchyme of both male and female embryos. A ∼147-kb BAC clone containing the Amhr2 locus was used to generate transgenic mice. The transgene was able to rescue the block in Müllerian duct regression of Amhr2-null males, suggesting that the BAC clone contains regulatory …

We have shown that membrane-associated guanylate kinase with inverted domain structure-1 (MAGI1), a scaffold protein with six PSD95/DiscLarge/ZO-1 (PDZ) domains, is involved in the regulation of endothelial cell (EC) activation and atherogenesis in mice. In addition to causing acute respiratory disease, influenza A virus (IAV) infection plays an important role in atherogenesis and triggers acute coronary syndromes and fatal myocardial infarction. Therefore, the aim of this study is to investigate the function and regulation of MAGI1 in IAV-induced EC activation. Whereas, EC infection by IAV increases MAGI1 expression, MAGI1 depletion suppresses IAV infection, suggesting that the induction of MAGI1 may …

Semiparametric Copula-Based Regression Modeling Of Semi-Competing Risks Data, Hong Zhu, Yu Lan, Jing Ning, Yu Shen

Faculty, Staff and Student Publications

Semi-competing risks data often arise in medical studies where the terminal event (e.g., death) censors the non-terminal event (e.g., cancer recurrence), but the non-terminal event does not prevent the subsequent occurrence of the terminal event. This article considers regression modeling of semi-competing risks data to assess the covariate effects on the respective non-terminal and terminal event times. We propose a copula-based framework for semi-competing risks regression with time-varying coefficients, where the dependence between the non-terminal and terminal event times is characterized by a copula and the time-varying covariate effects are imposed on two marginal regression models. We develop a two-stage …

Numerous studies have revealed the critical role of premature senescence induced by various cancer treatment modalities in the pathogenesis of aging-related diseases. Senescence-associated secretory phenotype (SASP) can be induced by telomere dysfunction. Telomeric DNA damage response induced by some cancer treatments can persist for months, possibly accounting for long-term sequelae of cancer treatments. Telomeric DNA damage-induced mitochondrial dysfunction and increased reactive oxygen species production are hallmarks of premature senescence. Recently, we reported that the nucleus-mitochondria positive feedback loop formed by p90 ribosomal S6 kinase (p90RSK) and phosphorylation of S496 on ERK5 (a unique member of the mitogen-activated protein kinase family …

Kidney Disease After Heart And Lung Transplantation, Carlos M Zapata, Hassan N Ibrahim

Faculty, Staff and Student Publications

Chronic kidney disease (CKD) is not only common after lung and heart transplantation but also is associated with increased morbidity and mortality due to multiple pre-, peri- and post-transplant factors. While the exact incidence of CKD in this population is not well-defined, it seems to have gradually increased over the years as older recipients are more frequently considered. The increasing success of the procedure and expanding transplant candidate pool has allowed many with comorbid conditions to receive a transplant, which was considered prohibitive in the past. This review presents risk factors that have been linked to CKD as well as …

Determinants Of Virus Variation, Evolution, And Host Adaptation, Katherine Latourrette, Hernan Garcia-Ruiz

Nebraska Center for Virology: Faculty Publications

Virus evolution is the change in the genetic structure of a viral population over time and results in the emergence of new viral variants, strains, and species with novel biological properties, including adaptation to new hosts. There are host, vector, environmental, and viral factors that contribute to virus evolution. To achieve or fine tune compatibility and successfully establish infection, viruses adapt to a particular host species or to a group of species. However, some viruses are better able to adapt to diverse hosts, vectors, and environments. Viruses generate genetic diversity through mutation, reassortment, and recombination. Plant viruses are exposed to …

One-Carbon Metabolism In Children With Marasmus And Kwashiorkor, Thaddaeus May, Bethany De La Haye, Gabrielle Nord, Kevin Klatt, Kevin Stephenson, Sara Adams, Lucy Bollinger, Neil Hanchard, Erland Arning, Teodoro Bottiglieri, Kenneth Maleta, Mark Manary, Farook Jahoor

Children’s Nutrition Research Center Staff Publications

BACKGROUND: Kwashiorkor is a childhood syndrome of edematous malnutrition. Its precise nutritional precipitants remain uncertain despite nine decades of study. Remarkably, kwashiorkor's disturbances resemble the effects of experimental diets that are deficient in one-carbon nutrients. This similarity suggests that kwashiorkor may represent a nutritionally mediated syndrome of acute one-carbon metabolism dysfunction. Here we report findings from a cross-sectional exploration of serum one-carbon metabolites in Malawian children.

METHODS: Blood was collected from children aged 12-60 months before nutritional rehabilitation: kwashiorkor (N = 94), marasmic-kwashiorkor (N = 43) marasmus (N = 118), moderate acute malnutrition (N = 56) and controls (N = …
