Advances in Clinical Medical Research and Healthcare Delivery

Diffuse large B cell lymphoma (DLBCL) is a type of non-Hodgkin lymphoma that can present in a variety of ways including fever, weight loss, weakness, and drenching night sweats. Uncommonly, hypercalcemia of malignancy can be associated with DLBCL through multiple mechanisms that include synthesis of parathyroid hormone related peptide (PTHrP) or elevated calcitriol levels. It is estimated that hypercalcemia in the setting of DLBCL is present in 18% of newly diagnosed cases. This report details a case of an 80-year-old man with history of chronic anemia and CKD stage 3b that presented with weakness, decreased oral intake, and self-reported weight ...

The Role Of The Hypoxia-Inducible Factor 2 In Pancreatic Cancer: Mechanisms Of Tumor Immunosuppression And Intestinal Radioprotection, Carolina Garcia Garcia

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with dismal prognosis. The only curative option for patients is surgery, but over 80% of patients are not surgical candidates. Unfortunately, PDAC is resistant to the three remaining options. PDAC is characterized by a profoundly hypoxic and immunosuppressive stroma, which contributes to its therapeutic recalcitrance. Alpha-smooth muscle actin+ (αSMA+) cancer-associated fibroblasts (CAFs) are the most abundant stromal component, as well as mediators of stromal deposition. The hypoxia-inducible factors (HIF1 and HIF2) coordinate responses to hypoxia, yet, despite their known association to poor patient outcomes, their functions within the PDAC tumor microenvironment (TME ...

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Advancements in immunotherapy treatments have become essential in the treatment of various cancers, such as those with high tumor burden like melanoma(Brahmer et al., 2012; Hodi et al., 2010). Immunotherapy, specifically immune checkpoint therapy (ICT) provides antagonist effect on specific immune checkpoints to control effector T cell functions(Pardoll, 2012). This therapy allows for the modulation of anti-tumor responses through the use of monoclonal antibodies, such as anti-CTLA-4 or anti-PD-1 that block the receptors from binding with their ligands, thus allowing for CD4+ and CD8+ T cell priming and activation(Wei et al., 2017). However, the required epigenetic and ...

Defining The Cooperation Between Mhc-I And Mhc-Ii Neoantigen-Driven T Cell Responses To Develop Effective Personalized Immunotherapies, Charmelle Williams

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Immune checkpoint therapy (ICT) (e.g. anti-CTLA-4 (α-CTLA-4), anti-PD-1 (α-PD-1)) enables durable T cell-dependent anti-tumor immunity in certain cancer patients. Since a subset of patients respond to ICT, this work aims at developing a more in-depth understanding of T-cell responses to MHC class I (MHC-I) and MHC class II (MHC-II) tumor antigens that are derived from aberrant expression of non-mutant antigens or driver and passenger somatic alterations that can function as tumor neoantigens. We used a poorly immunogenic Brafv600e Pten-/- Cdkn2a-/- YUMM1.7 (Y1.7) murine melanoma line with a paucity of endogenous neoantigens that is unresponsive to ICT ...

Leveraging Single Cell Technologies For The Characterization And Treatment Of Refractory Pancreatic Cancer, Maria Monberg

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Heterogeneity is a hallmark of cancer, and the advent of multimodal single-cell technologies has helped uncover heterogeneity in a high-throughput manner in different cancers across varied contexts at an unprecedented resolution. In an effort to improve precision medicine approaches in pancreatic ductal adenocarcinoma (PDAC), a highly lethal malignancy with a mere 11% 5-year survival rate, this dissertation focuses on first questioning the assumptions of the most basic models used to study PDAC via multimodal single-cell characterization methods at multiple levels of biological organization (scCNVseq and snATACseq for DNA assays, scRNAseq for transcriptomics, and paired protein assays such as multiplexed immunofluorescence ...

At the center of the SARS-CoV2 infection, the spike protein and its interaction with the human receptor ACE2 play a central role in the molecular machinery of SARS-CoV2 infection of human cells. Vaccine therapies are a valuable barrier to the worst effects of the virus and to its diffusion, but the need of purposed drugs is emerging as a core target of the fight against COVID19. In this respect, the repurposing of drugs has already led to discovery of drugs thought to reduce the effects of the cytokine storm, but still a drug targeting the spike protein, in the infection ...

Due to the diversity and breadth of cancer characteristics, the study and elimination of cancerous cells is a daunting task. Despite this diversity cancer cell share common characteristics such as anti‐apoptotic mechanisms and avoidance of immune destruction. The importance of the immune system in counteracting these diverse characteristics has only recently begun to be appreciated but involvement of the immune system is quickly becoming an essential component in the development of novel cancer therapies. The following study aims to elucidate the effect of SMAC mimetics, a class of targeted therapy drugs, on T cells and their potentially induced proliferation ...


Jnk And Nf-Κb Cell Signaling Pathways In Cardiovascular Disease Present Potential Targets For Curcumin Therapy, Mary Richfield 2022 Liberty University

Jnk And Nf-Κb Cell Signaling Pathways In Cardiovascular Disease Present Potential Targets For Curcumin Therapy, Mary Richfield

Senior Honors Theses

Curcumin (diferuloylmethane) is a compound derived from the rhizomes of Curcumin longa that has been long used for medicinal purposes. Curcumin alleviates the pathology of cardiovascular diseases, including atherosclerosis, aneurysm, and cardiomyopathy. The mechanism of curcumin therapy is under active research. The NF-κB and JNK pathways are two that curcumin interacts with to block inflammatory processes, apoptosis, and fibrotic tissue remodeling to prevent the pathologies of cardiovascular disease. While curcumin has demonstrated powerful mediation of cardiovascular disease, its bioavailability in body tissues is limited due to the instability and hydrophobicity of its structure. Further work is underway to stabilize curcumin ...


Selective Gsk3Β Inhibition Mediates An Nrf2-Independent Anti-Inflammatory Microglial Response, Mohamed H. Yousef 2022 The American University in Cairo AUC

Selective Gsk3Β Inhibition Mediates An Nrf2-Independent Anti-Inflammatory Microglial Response, Mohamed H. Yousef

Theses and Dissertations

Glycogen Synthase Kinase 3 (GSK3) is associated with the proinflammatory phenotype of microglia and has been shown to act in concert with Nuclear factor kappa B (NF-κB). . GSK3 is also a suppressor of Nuclear factor erythroid 2-related factor 2 (Nrf2), the principal regulator of redox homeostasis. Agreeing with the oxidative paradigm of aging, Nrf2 is often deregulated in parainflammatory and neurodegenerative diseases. In this study, we aimed to explore a multimodal disease-modifying utility of GSK3 inhibition, beyond neuronal proteopathologies, Furthermore, we aimed to underscore the difference in therapeutic value between the two GSK3 paralogs by isoform-selective chemical inhibition.

The anti-inflammatory ...

The Application Of The Skin Virome For Human Identification, Ema H. Graham, Jennifer Clarke, Samodha Fernando, Joshua Herr, Michael Adamowicz

Virology Papers

The use of skin virome offers a unique approach for human identification purposes in instances where a viable and statistically relevant human DNA profile is unavailable. The skin virome may act as an alternative DNA profile and/or an additional form of probative genetic material. To date, no study has attempted to investigate the human virome over a time series across various physical locations of the body to identify its diagnostic potential as a tool for human identification. For this study, we set out to evaluate the stability, diversity, and individualization of the human skin virome. An additional goal was ...

Adenoviral-Vectored Centralized Consensus Hemagglutinin Vaccine Provides Broad Protection Against H2 Influenza A Virus, Erika M. Petro-Turnquist, Brianna L. Bullard, Matthew J. Pekarek, Eric A. Weaver

Virology Papers

Several influenza pandemics have occurred in the past century, one of which emerged in 1957 from a zoonotic transmission of H2N2 from an avian reservoir into humans. This pandemic caused 2–4 million deaths and circulated until 1968. Since the disappearance of H2N2 from human populations, there has been waning immunity against H2, and this subtype is not currently incorporated into seasonal vaccines. However, H2 influenza remains a pandemic threat due to consistent circulation in avian reservoirs. Here, we describe a method of pandemic preparedness by creating an adenoviral-vectored centralized consensus vaccine design against human H2 influenza. We also assessed ...

Expanding Mouse-Adapted Yamagata-Like Influenza B Viruses In Eggs Enhances In Vivo Lethality In Balb/C Mice, Matthew J. Pekarek, Erika M. Petro-Turnquist, Adam Rubrum, Richard J. Webby, Eric A. Weaver

Virology Papers

Despite the yearly global impact of influenza B viruses (IBVs), limited host range has been a hurdle to developing a readily accessible small animal disease model for vaccine studies. Mouseadapting IBV can produce highly pathogenic viruses through serial lung passaging in mice. Previous studies have highlighted amino acid changes throughout the viral genome correlating with increased pathogenicity, but no consensus mutations have been determined. We aimed to show that growth system can play a role in mouse-adapted IBV lethality. Two Yamagata-lineage IBVs were serially passaged 10 times in mouse lungs before expansion in embryonated eggs or Madin–Darby canine kidney ...

Virology Papers

Influenza A virus of swine (IAV-S) is an economically important swine pathogen. The IAV-S hemagglutinin (HA) surface protein is the main target for vaccine development. In this study, we evaluated the feasibility of using the recombinant tri-segmented Pichinde virus (rPICV) as a viral vector to deliver HA antigen to protect pigs against IAV-S challenge. Four groups of weaned pigs (T01–T04) were included in the study. T01 was injected with PBS to serve as a non-vaccinated control. T02 was inoculated with rPICV expressing green fluorescence protein (rPICV-GFP). T03 was vaccinated with rPICV expressing the HA antigen of the IAV-S H3N2 ...


Determinants Of Virus Variation, Evolution, And Host Adaptation, Katherine LaTourrette, Hernan Garcia-Ruiz 2022 University of Nebraska-Lincoln

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

Virology Papers

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 ...


The Effect Of Creatine On Immortalized Schwann Cell Proliferation, Peyton Kimmel, Caitlyn Henry, Angela Asirvatham 2022 Misericordia University

The Effect Of Creatine On Immortalized Schwann Cell Proliferation, Peyton Kimmel, Caitlyn Henry, Angela Asirvatham

Student Research Poster Presentations 2022

Creatine is an important component of the high-energy phosphate transfer to regulate cellular levels of ATP. The functions of creatine supplementation are well studied in the muscular and skeletal system, however the impact of creatine in the nervous system, specifically Schwann cells, is relatively unknown. Schwann cell growth in vitro is facilitated by heregulin, a neuron secreted growth factor, and forskolin, a pharmacological agent that activates cAMP. In peripheral nervous system injuries, recovery time is based around Schwann cell’s ability to proliferate and differentiate, and it is unknown what role creatine plays in this process. It was hypothesized that ...

Department of Medicine Faculty Papers

The Creb-Regulated Transcriptional Coactivator (Crtc) family of transcriptional coregulators drive Creb1-mediated transcription effects on metabolism in many tissues, but the in vivo effects of Crtc2/Creb1 transcription on skeletal muscle metabolism are not known. Skeletal muscle-specific overexpression of Crtc2 (Crtc2 mice) induced greater mitochondrial activity, metabolic flux capacity for both carbohydrates and fats, improved glucose tolerance and insulin sensitivity, and increased oxidative capacity, supported by upregulation of key metabolic genes. Crtc2 overexpression led to greater weight loss during alternate day fasting (ADF), selective loss of fat rather than lean mass, maintenance of higher energy expenditure during the fast and reduced ...
