The Systemic Quantification Of Immune Cell Populations In Various Murine Models: How Age, Tumor Burden, And Immunotherapy Affect The Immune Response, Kavita Sinha
Honors Scholar Theses
Immunotherapy as a form of cancer treatment has become increasingly popular in the past few decades. Researchers have worked to figure out how to best use the body’s natural defense mechanism, the immune system, to fight off and destroy cancer cells. In particular, the goal has been to manipulate checkpoint blockades such as CTLA-4 and PD-1 in order to take the breaks off of the immune system, allowing for a prolonged immune response to the cancer. This work has led to the development of human versions of anti-CTLA4 antibodies (ipilimumab, tremelimumab) and anti-PD1 antibodies (pembrolizumab and Nivolumab) that are ...

Background: Elevated systemic blood pressure (SBP) has been linked to complications in Continuous-flow left ventricular assist devices (CF-LVADs), including stroke and pump thrombosis. We queried Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) to describe the response of SBP to CF-LVAD implantation and to delineate contemporary trends in antihypertensive (AH) utilization for patients with these pumps. Methods: We identified all CF-LVAD implantations in patients older than 18 years from 2006-2014, excluding those whose durations were less than 30 days. Pre-implant patient demographics and characteristics were obtained for each record. SBPs [i.e., mean arterial pressures (MAPs)], AH-use data, and vital ...

Assessing Speech-Language Pathologists’ Knowledge And Use Of Language Acquisition Through Motor Planning, Mary Catherine Cazalas
Many individuals who are nonverbal require augmentative and alternative communication devices to communicate. The purpose of this research was to assess speech-language pathologists’ knowledge of a particular method of implementing augmentative and alternative communication devices known as language acquisition through motor planning (LAMP). Further, this research was designed to determine the percentage of speech pathologists who have used LAMP during their careers as well as the perceived level of success speech pathologists have found with LAMP. Mississippi speech-language pathologists were used as the sample for this study. A survey was created electronically via the online survey development software, “Survey Monkey ...
Identification Of Epigenetic Regulators Of Dux4-Fl For Targeted Therapy Of Facioscapulohumeral Muscular Dystrophy, 2018 University of Massachusetts Medical School
Identification Of Epigenetic Regulators Of Dux4-Fl For Targeted Therapy Of Facioscapulohumeral Muscular Dystrophy, Charis L. Himeda, Takako I. Jones, Ching-Man A. Virbasius, Lihua Julie Zhu, Michael R. Green, Peter L. Jones
Open Access Articles
Facioscapulohumeral muscular dystrophy (FSHD) is caused by epigenetic de-repression of the disease locus, leading to pathogenic misexpression of the DUX4 gene in skeletal muscle. While the factors and pathways involved in normal repression of the FSHD locus in healthy cells have been well characterized, very little is known about those responsible for the aberrant activation of DUX4-fl in FSHD myocytes. Reasoning that DUX4-fl activators might represent useful targets for small molecule inhibition, we performed a highly targeted, candidate-based screen of epigenetic regulators in primary FSHD myocytes. We confirmed several of the strongest and most specific candidates (ASH1L, BRD2, KDM4C, and ...

Acute on chronic liver failure (ACLF) is a culmination of chronic liver disease and extra-hepatic organ failures, which is associated with a high short-term mortality and immense healthcare expenditure. There are varying definitions for organ failures and ACLF in Europe, North America and Asia. These differing definitions need to be reconciled to enhance progress in the field. The pathogenesis of ACLF is multi-factorial and related to interactions between the immuno-inflammatory system, microbiota and the precipitating factors. Individual organ failures related to the kidney, brain, lungs and circulation have cumulative adverse effects on mortality and are often complicated or precipitated by ...

Photochemical Control Of Protein Arginine Deiminase (Pad) Activity, Santanu Mondal, Sangram S. Parelkar, Mitesh Nagar, Paul R. Thompson
Thompson Lab Publications
Protein Arginine deiminases (PADs) play an important role in the pathogenesis of various diseases, including rheumatoid arthritis, multiple sclerosis, lupus, ulcerative colitis and breast cancer. Therefore, the development of PAD-inhibitors has drawn significant research interest in recent years. Herein, we describe the development of the first photoswitchable PAD-inhibitors. These compounds possess an azobenzene photoswitch to optically control PAD activity. Screening of a series of inhibitors structurally similar to BB-Cl-Amidine afforded compounds 1 and 2 as the most promising candidates for the light-controlled inhibition of PAD2; the cis-isomer of 1 is 10-fold more potent than its trans-isomer, whereas the trans-isomer of ...

Methods: Using a cross-sectional study design, we compared reported pain and pain management between non-Hispanic White and non-Hispanic Black newly admitted nursing home residents with cancer (n=342,920) using the de-identified Minimum Data Set version 3.0. Pain management strategies included the use of scheduled analgesics, pro re nata analgesics, and non-pharmacological methods. Presence of pain was based on self-report when ...
Bb-Cl-Amidine As A Novel Therapeutic For Canine And Feline Mammary Cancer Via Activation Of The Endoplasmic Reticulum Stress Pathway, Melissa M. Ledet, Robyn Anderson, Rebecca Harman, Aaron Muth, Paul R. Thompson, Scott A. Coonrod, Gerlinde R. Van De Walle
Open Access Articles
BACKGROUND: Mammary cancer is highly prevalent in dogs and cats and results in a poor prognosis due to critically lacking viable treatment options. Recent human and mouse studies have suggested that inhibiting peptidyl arginine deiminase enzymes (PAD) may be a novel breast cancer therapy. Based on the similarities between human breast cancer and mammary cancer in dogs and cats, we hypothesized that PAD inhibitors would also be an effective treatment for mammary cancer in these animals.
METHODS: Canine and feline mammary cancer cell lines were treated with BB-Cl-Amidine (BB-CLA) and evaluated for viability and tumorigenicity. Endoplasmic reticulum stress was tested ...
Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, 2018 Louisiana State University and Agricultural and Mechanical College
Paclitaxel Enhances Oncolytic Potential Of Herpes Simplex Virus Type-1 In Cancer Cells, Misagh Naderi
LSU Master's Theses
Taxanes are spindle poisons that bind to and stabilize microtubules resulting in mitotic arrest. Herpes simplex Typ-1 (HSV-1) virions utilize the microtubular network for intracellular transport during both virus entry and virus egress from infected cells. It has been reported previously that taxanes may synergize with oncolytic herpes simplex viruses in the treatment of experimental prostate and breast tumors in mice. Other reports have indicated that taxanes may inhibit viral replication in infected cells. In this study the previously characterized Oncolytic Herpes Simplex Virus type 1 (OSVP), which was constructed in Kousoulas lab was used in conjugation with paclitaxel (taxol ...

Towards An Arthritis Flare-Responsive Drug Delivery System, Nitin Joshi, Ellen M. Gravallese, Joerg Ermann, Jeffrey M. Karp
Open Access Articles
Local delivery of therapeutics for the treatment of inflammatory arthritis (IA) is limited by short intra-articular half-lives. Since IA severity often fluctuates over time, a local drug delivery method that titrates drug release to arthritis activity would represent an attractive paradigm in IA therapy. Here we report the development of a hydrogel platform that exhibits disassembly and drug release controlled by the concentration of enzymes expressed during arthritis flares. In vitro, hydrogel loaded with triamcinolone acetonide (TA) releases drug on-demand upon exposure to enzymes or synovial fluid from patients with rheumatoid arthritis. In arthritic mice, hydrogel loaded with a fluorescent ...

Discovery And Effects Of Pharmacological Inhibition Of The E3 Ligase Skp2 By Small Molecule Protein-Protein Interaction Disruptors, 2018 The University of Texas M D Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences
Discovery And Effects Of Pharmacological Inhibition Of The E3 Ligase Skp2 By Small Molecule Protein-Protein Interaction Disruptors, John K. Morrow
UT GSBS Dissertations and Theses (Open Access)
Skp2 (S-phase kinase-associated protein 2), one component of the SCF E3 ubiquitin ligase complex, directly interacts with Skp1 and indirectly associates with Cullin1 and Rbx1 to bridge the E2 conjugating enzyme with its protein substrate to execute its E3 ligase activity. Skp2 is an Fbox protein (due to it containing an Fbox domain) and it is the rate-limiting component of the SCF complex. Skp2 targets several cell-cycle regulatory proteins for ubiquitination and degradation; most notable and significant for cancer are the cyclin-dependent kinase inhibitor, p27. Skp2 is an oncogene and studies have shown that over-expression of Skp2 leads to increased ...

Ajulemic Acid: Potential Treatment For Chronic Inflammation, Sumner Burstein
Open Access Articles
Ajulemic acid (AJA, CT-3, IP-751, JBT-101, anabasum) is a first-in-class, synthetic, orally active, cannabinoid-derived drug that preferentially binds to the CB2 receptor and is nonpsychoactive. In preclinical studies, and in Phase 1 and 2 clinical trials, AJA showed a favorable safety, tolerability, and pharmacokinetic profile. It also demonstrated significant efficacy in preclinical models of inflammation and fibrosis. It suppresses tissue scarring and stimulates endogenous eicosanoids that resolve chronic inflammation and fibrosis without causing immunosuppression. AJA is currently being developed for use in 4 separate but related indications including systemic sclerosis (SSc), cystic fibrosis, dermatomyositis (DM), and systemic lupus erythematosus. Phase ...

Individuals with type 2 diabetes (T2D) and dyslipidemia are at an increased risk of cardiovascular disease. Fibrates are a class of drugs prescribed to treat dyslipidemia, but variation in response has been observed. To evaluate common and rare genetic variants that impact lipid responses to fenofibrate in statin‐treated patients with T2D, we examined lipid changes in response to fenofibrate therapy using a genomewide association study (GWAS). Associations were followed‐up using gene expression studies in mice. Common variants in SMAD3 and IPO11 were marginally associated with lipid changes in black subjects (P < 5 × 10‐6). Rare variant and gene expression changes ...

RNA-based drugs depend on chemical modifications to increase potency and nuclease stability, and to decrease immunogenicity in vivo. Chemical modification will likely improve the guide RNAs involved in CRISPR-Cas9-based therapeutics as well. Cas9 orthologs are RNA-guided microbial effectors that cleave DNA. No studies have yet explored chemical modification at all positions of the crRNA guide and tracrRNA cofactor. Here, we have identified several heavily-modified versions of crRNA and tracrRNA that are more potent than their unmodified counterparts. In addition, we describe fully chemically modified crRNAs and tracrRNAs (containing no 2'-OH groups) that are functional in human cells. These designs ...

The type 2 immune response is the central mechanism of disease progression in schistosomiasis, but the signals that induce it after infection remain elusive. Aberrant microRNA (miRNA) expression is a hallmark of human diseases including schistosomiasis, and targeting the deregulated miRNA can mitigate disease outcomes. Here, we demonstrate that efficient and sustained elevation of miR-203-3p in liver tissues, using the highly hepatotropic recombinant adeno-associated virus serotype 8 (rAAV8), protects mice against lethal schistosome infection by alleviating hepatic fibrosis. We show that miR-203-3p targets interleukin-33 (IL-33), an inducer of type 2 immunity, in hepatic stellate cells to regulate the expansion and ...
