Hdl In Endocrine Carcinomas: Biomarker, Drug Carrier, And Potential Therapeutic, Emily E. Morin, Xiang-An Li, Anna Schwendeman

Physiology Faculty Publications

High-density lipoprotein (HDL) have long been studied for their protective role against cardiovascular diseases, however recently relationship between HDL and cancer came into focus. Several epidemiological studies have shown an inverse correlation between HDL-cholesterol (HDL-C) and cancer risk, and some have even implied that HDL-C can be used as a predictive measure for survival prognosis in for specific sub-population of certain types of cancer. HDL itself is an endogenous nanoparticle capable of removing excess cholesterol from the periphery and returning it to the liver for excretion. One of the main receptors for HDL, scavenger receptor type B-I (SR-BI), is highly …

Development Of A Pd-L1 Pet Imaging Biomarker, Caleb Jack Bridgwater

Posters-at-the-Capitol

Immunotherapy strategies are very promising treatments for cancer patients. Specifically, Immune checkpoint inhibitor therapy focusing on the PD-1/PD-L1 pathway shows long-lasting positive results in many cancer patients. Unfortunately, not all the patients can benefit from this highly effective treatment. Hence, there is a great need for predictive biomarkers. Immunohistochemical (IHC) staining has been used as a way of predicting patient response, yet shows many problems. For example, IHC utilizes an invasive biopsy and sample fixing, which creates an incomplete and delayed picture of the patient’s biochemistry and the tumor microenvironment, consequently ignoring metastases.

The purpose of this study is to …

Ethical Implications Of Treatment For Gender Dysphoria In Youth, Kelsey Hayes

Journal of Health Ethics

This manuscript explores ethical implications on treatment for youth with diagnosed gender dysphoria. The ethical considerations outlined and analyzed in this essay involve illuminating an understanding of whether the administration of pubertal suppression with GnRH agonists, and cross-sex hormones to children with gender dysphoria is morally justified as treatment to manage their psychological distress, or if safer more understood alternatives exist. This essay emphasizes that as health care professionals we must ensure youth with gender dysphoria receive adequate medical treatment and care however, this essay concludes through extensive literature review, that the use of inconclusive and under researched methods to …

Sanders-Brown Center on Aging Faculty Publications

Sulfonylureas are a class of antidiabetes medications prescribed to millions of individuals worldwide. Rodents have been used extensively to study sulfonylureas in the laboratory. Here, we report the results of studies treating mice with a sulfonylurea (glimepiride) in order to understand how the drug affects glucose homeostasis and tolerance. We tested the effect of glimepiride on fasting blood glucose, glucose tolerance, and insulin secretion, using glimepiride sourced from a local pharmacy. We also examined the effect on glucagon, gluconeogenesis, and insulin sensitivity. Unexpectedly, glimepiride exposure in mice was associated with fasting hyperglycemia, glucose intolerance, and decreased insulin. There was no …

Pharmacy Faculty Articles and Research

Myocardial toxicity and drug resistance caused by drug efflux are major limitations of doxorubicin (Dox)-based chemotherapy. Dox structure modification could be used to develop conjugates with an improved biological profile, such as antiproliferative activity and higher cellular retention. Thus, Dox thiol conjugates, Dox thiol (Dox-SH), thiol-reactive Dox-SS-pyridine (SS = disulfide), and a Dox-SS-cell-penetrating cyclic peptide, Dox-SS-[C(WR)4K], were synthesized. Dox was reacted with Traut's reagent to generate Dox-SH. The thiol group was activated by the reaction with dithiodipyridine to afford the corresponding Dox-SS-Pyridine (Dox-SS-Pyr). A cyclic cell-penetrating peptide containing a cysteine residue [C(WR)4K] was prepared using Fmoc solid-phase strategy. Dox-SS-Py was …

This paper assesses the influence of a number of factors taken into account when a brand name drug is replaced by a generic one. It also evaluates responses of health professionals – physicians and pharmacist—and patients regarding the issue of switching. We compared and contrasted their responses in order to identify new points of cooperation for the intended benefit of the patient. Thus, the sample drew from all three groups, consisting of 50 doctors, 50 pharmacists, and 50 patients. We collected information regarding the age, residence, income level, and education level for the patients, and age and experience for the …

Oxcarbazepine Overdose In A Polysubstance Related Suicide, Melissa Beals, Robert J. Krumsick, C. Clinton Frazee Iii, Lindsey J. Haldiman, Uttam Garg

Posters

Introduction
Oxcarbazepine is a derivative of carbamazepine that is used primarily in the treatment of epilepsy, and experimentally as a mood-stabilizer in adjunctive therapy for the treatment of bipolar disorder. Oxcarbazepine is converted through oxidation to its pharmacologically active metabolite 10-OH-Carbazepine, which is thought to be responsible for most of the anticonvulsant action of the drug. Adverse effects of oxcarbazepine are generally dose-dependent and may include fatigue, somnolence, dizziness, diplopia, nystagmus, and ataxia. Additive sedative effects have been noted when oxcarbazepine is used in combination with other CNS depressionproducing medications. Furthermore, oxcarbazepine and 10-OH-Carbazepine are powerful CYP2C19 inhibitors, potentially increasing …

Pregnancy Anxiety Predicts Shorter Gestation In Latina And Non-Latina White Women: The Role Of Placental Corticotrophin-Releasing Hormone, Isabel F. Ramos, Christine M. Guardino, Maxwell Mansolf, Laura M. Glynn, Curt A. Sandman, Calvin J. Hobel, Christine Dunkel Schetter

Psychology Faculty Articles and Research

Objective

Previous research has shown that a woman’s anxiety about her pregnancy predicts gestational length. Placental corticotrophin-releasing hormone (CRH) is a stress-responsive peptide proposed as a mechanism. We examined placental CRH as a physiological mediator of the association between pregnancy anxiety and gestational length in Latina and non-Latina White women to replicate evidence of associations between pregnancy anxiety, placental CRH and gestational length; to test whether placental CRH levels or changes mediate effects of pregnancy anxiety on gestational length; to examine ethnic differences in pregnancy anxiety, placental CRH, and gestational length; and to explore whether the effects of pregnancy anxiety …

Maternal Programming: Application Of A Developmental Psychopathology Perspective, Laura M. Glynn, Mariann A. Howland, Molly Fox

Psychology Faculty Articles and Research

The fetal phase of life has long been recognized as a sensitive period of development. Here we posit that pregnancy represents a simultaneous sensitive period for the adult female with broad and persisting consequences for her health and development, including risk for psychopathology. In this review, we examine the transition to motherhood through the lens of developmental psychopathology. Specifically, we summarize the typical and atypical changes in brain and behavior that characterize the perinatal period. We highlight how the exceptional neuroplasticity exhibited by women during this life phase may account for increased vulnerability for psychopathology. Further, we discuss several modes …

“Do We Know Jack” About Jak? A Closer Look At Jak/Stat Signaling Pathway, Emira Bousoik, Hamidreza Montazeri Aliabadi

Pharmacy Faculty Articles and Research

Janus tyrosine kinase (JAK) family of proteins have been identified as crucial proteins in signal transduction initiated by a wide range of membrane receptors. Among the proteins in this family JAK2 has been associated with important downstream proteins, including signal transducers and activators of transcription (STATs), which in turn regulate the expression of a variety of proteins involved in induction or prevention of apoptosis. Therefore, the JAK/STAT signaling axis plays a major role in the proliferation and survival of different cancer cells, and may even be involved in resistance mechanisms against molecularly targeted drugs. Despite extensive research focused on the …

The mechanistic target of rapamycin (mTOR) is a nutrient sensor of eukaryotic cells. Inhibition of mechanistic mTOR signaling can increase life and health span in various species via interventions that include rapamycin and caloric restriction (CR). In the central nervous system, mTOR inhibition demonstrates neuroprotective patterns in aging and Alzheimer’s disease (AD) by preserving mitochondrial function and reducing amyloid beta retention. However, the effects of mTOR inhibition for in vivo brain physiology remain largely unknown. Here, we review recent findings of in vivo metabolic and vascular measures using non-invasive, multimodal neuroimaging methods in rodent models for brain aging and AD. …

Human Immunodefciency Virus Type 1 (HIV-1) remains one of the leading causes of death worldwide. Present combination antiretroviral therapy has substantially improved HIV-1 related pathology. However, delivery of therapeutic agents to the HIV reservoir organ like Central nervous system (CNS) remains a major challenge primarily due to the inefective transmigration of drugs through Blood Brain Barrier (BBB). The recent advent of nanomedicine-based drug delivery has stimulated the development of innovative systems for drug delivery. In this regard, particular focus has been given to nanodiamond due to its natural biocompatibility and non-toxic nature–making it a more efcient drug carrier than other …

Cancer stem cells promote neoplastic growth, in part by deregulating asymmetric cell division and enhancing self-renewal. To uncover mechanisms and potential therapeutic targets in glioma stem cell (GSC) self-renewal, we performed a genetic suppressor screen for kinases to reverse the tumor phenotype of our Drosophila brain tumor model and identified dCdk5 as a critical regulator. CDK5, the human ortholog of dCdk5 (79% identity), is aberrantly activated in GBMs and tightly aligned with both chromosome 7 gains and stem cell markers affecting tumor-propagation. Our investigation revealed that pharmaceutical inhibition of CDK5 prevents GSC self-renewal in vitro and in xenografted tumors, at …

Lysophosphatidic acid (LPA) is a synaptic phospholipid, which regulates cortical excitation/inhibition (E/I) balance and controls sensory information processing in mice and man. Altered synaptic LPA signaling was shown to be associated with psychiatric disorders. Here, we show that the LPA-synthesizing enzyme autotaxin (ATX) is expressed in the astrocytic compartment of excitatory synapses and modulates glutamatergic transmission. In astrocytes, ATX is sorted toward fine astrocytic processes and transported to excitatory but not inhibitory synapses. This ATX sorting, as well as the enzymatic activity of astrocyte-derived ATX are dynamically regulated by neuronal activity via astrocytic glutamate receptors. Pharmacological and genetic ATX inhibition …

Multiple myeloma (MM) is a neoplastic plasma-cell disorder. This is characterized by clonal proliferation of malignant plasma cells in the bone-marrow (BM) microenvironment, monoclonal protein in blood or urine, and associated organ dysfunction. The treatment options approved by FDA are immune-modulatory agents, proteasome inhibitors, and autologous stem cell transplantation (ASCT). Unfortunately, MM remains uniformly fatal owing to intrinsic or acquired drug resistance and the median survival time is 3 to 5 years. Thus, there is a great need for novel strategies to combat MM.

The intimate relationship of myeloma cells to BM microenvironment is “hallmark of myeloma”. The homing of …

Infections Not Fought: Antibiotic Resistance In Underserved Communities, Derek Lillestolen

Senior Honors Theses

In 1928, the profound effects of penicillin were discovered and antibiotic treatments became extremely popular. Broad-spectrum antibiotics, like tetracyclines, have been since branded as cure-all prescriptions and used profusely in the Western World and abroad. Due to ignorance of specific biochemical mechanisms and the misuse of antibiotics these drugs inadvertently allowed the rise in prevalence of antibiotic resistant strains of certain bacteria as the century progressed. Now, the specific genetic causes and mechanisms of antibiotic resistance are being understood, but the fight against antimicrobial resistance is far from over. In the United States, thousands of fatalities are caused annually by …

Peripheral artery disease is one of the most prevalent cardiovascular diseases in the United States and worldwide. It is estimated that over 8 million people in the United States are affected with peripheral artery disease, and up to 40% of people over 80 years old may have some degree of the disease. Peripheral artery disease can increase one’s chances for having other cardiovascular co-morbidities such as coronary artery disease, among others. Current interventional strategies are endovascular treatments such as transluminal angioplasty and stenting, or in more advanced cases peripheral artery bypass grafting. Medical interventions focus on managing symptoms and treating …

A Cytotoxic Evaluation Of A Chalcone Derivative Library On A549 Cells, Mary Elaine Kuo

Undergraduate Theses

Chalcones, a precursor to flavonoids, are chemical compounds found naturally in plants. The chalcones’ structure consists of a ketone bridge attached to two aromatic rings. Varying substituents on the aromatic rings allow for different affects, including anti-cancer properties. As a Michael acceptor, chalcones interact with pathways that cause inhibition of the initiation, promotion, and progression of cancer tumors. We have screened 32 compounds for growth inhibition in lung cells that vary the flexibility and confirmation of the 3 carbon bridge between the two aromatic rings as well as the effects of electronic modifications to the aromatic ring. We have found …

School of Medicine Publications

Chemotherapy is one of themajor therapeutic options for cancer treatment. Chemotherapy is often associated with a low therapeutic window due to its poor specificity towards tumor cells/tissues. Antibody-drug conjugate (ADC) technology may provide a potentially new therapeutic solution for cancer treatment. ADC technology uses an antibody-mediated delivery of cytotoxic drugs to the tumors in a targeted manner, while sparing normal cells. Such a targeted approach can improve the tumor-to-normal tissue selectivity and specificity in chemotherapy. Considering its importance in cancer treatment, we aim to review recent efforts for the design and development of ADCs. ADCs are mainly composed of an …

Cost-Effectiveness Of Alternative Anticoagulation Strategies For Postoperative Management Of Total Knee Arthroplasty Patients, Savannah R. Smith, Jeffrey Katz, Elena Losina

GW Research Days 2016 - 2020

Background: Anticoagulation is essential for deep vein thrombosis (DVT) and pulmonary embolism (PE) prevention following total knee arthroplasty (TKA). Some research has suggested that longer duration anticoagulation can substantially reduce the risks of DVT and PE; however, in the absence of definitive recommendations, physicians are left weighing the risks of DVT and PE against those of anticoagulation, including gastrointestinal (GI) and central nervous system (CNS) hemorrhage and increased likelihood of prosthetic joint infection (PJI). We conducted a cost-effectiveness analysis to evaluate the benefits and risks of 14- and 35-day therapy with the most commonly prescribed anticoagulants post-TKA.

Background: Anticoagulation is …

We performed a retrospective review of all cases that used Onyx between October 2010 and July 2016 at a single tertiary care academic university urban hospital. Institutional review board approval was appropriately obtained. Initial case selection was …

Pupillometric Assessment Of Small Doses Of Opioid In A Pediatric Population, David Strum, Elizabeth Malphrus, Kevin Jackson, Julia Finkel

GW Research Days 2016 - 2020

According to the CDC, opioid prescriptions in the United States have more than tripled from 1999-2014, which has correlated with the staggering increase in opioid-involved drug overdose deaths. This pattern of prescription is thought to be a major contributory factor to the increase in drug overdose in America, as four out of five new heroin users started by misusing prescription painkillers. Providers need the means to objectively monitor analgesic efficacy of treatment in patients with pain to mitigate unnecessary analgesic prescribing.

It is well established that mu opioid agonists like morphine cause miosis, an effect to which tolerance does not …
