Inhibition of the protein phosphatase calcineurin (CN) ameliorates pathophysiologic and cognitive changes in aging rodents and mice with aging-related Alzheimer's disease (AD)-like pathology. However, concerns over adverse effects have slowed the transition of common CN-inhibiting drugs to the clinic for the treatment of AD and AD-related disorders. Targeting substrates of CN, like the nuclear factor of activated T cells (NFATs), has been suggested as an alternative, safer approach to CN inhibitors. However, small chemical inhibitors of NFATs have only rarely been described. Here, we investigate a newly developed neuroprotective hydroxyquinoline derivative (Q134R) that suppresses NFAT signaling, without inhibiting CN activity. …

Athletic Training and Clinical Nutrition Faculty Publications

BACKGROUND: Previous work in HEK-293 cells demonstrated the importance of amino acid-induced mTORC1 translocation to the lysosomal surface for stimulating mTORC1 kinase activity and protein synthesis. This study tested the conservation of this amino acid sensing mechanism in human skeletal muscle by treating subjects with chloroquine-a lysosomotropic agent that induces in vitro and in vivo lysosome dysfunction.

METHODS: mTORC1 signaling and muscle protein synthesis (MPS) were determined in vivo in a randomized controlled trial of 14 subjects (10 M, 4 F; 26 ± 4 year) that ingested 10 g of essential amino acids (EAA) after receiving 750 mg of chloroquine …

Materials and methods: A cross-sectional study was conducted at two institutes in Karachi from 2018 to 2019. All residents registered in the internal medicine program for at least 6 months were invited to participate via an online survey. An abbreviated version of the Maslach Burnout scale was used …

Development Of Parameters Towards Voice Bifurcations, Takeshi Ikuma, Andrew J. Mcwhorter, Lacey Adkins, Melda Kunduk

School of Medicine Faculty Publications

Pathological vocal folds are known to exhibit multiple oscillation patterns, depending on tissue imbalance, subglottal pressure level, and other factors. This includes mid-phonation changes due to bifurcations in the underlying voice source system. Knowledge of when changes in oscillation patterns occur is helpful in the assessments of voice disorders, and the knowledge could be transformed into useful objective measures. Mid-phonation bifurcations can occur in rapid succession; hence, a fast classification of oscillation pattern is critical to minimize the averaging of data across bifurcations. This paper proposes frequency-ratio based short-term measures, named harmonic disturbance factor (HDF) and biphonic index (BI), towards …

Assessment Of Microrna (Mir)-365 Effects On Oral Squamous Carcinoma Cell Line Phenotypes, Jeffery Coon, Karl Kingsley

Dental Medicine Faculty Research

miR-365 is a microRNA that regulates transcription and has been demonstrated to promote oncogenesis and metastasis in some cancers while suppressing these effects in others. Virtually no information is known about the presence or function of miR-365 in oral cancers. Based upon this information, the primary goal of this project was to evaluate the expression of miR-365 in existing oral cancer cell lines. Five commercially available oral cancer cell lines (SCC4, SCC9, SCC15, SCC25, and CAL27) were obtained and cultured. RNA was then screened by PCR using primers specific for miR-365, as well as matrix metalloproteinase (MMP-2) and a downstream …

The request and purchase of TV advertised foods were assessed through the frequency of children’s requests to purchase TV advertised foods and the frequency of parents’ purchases of these advertised foods, as well as the frequency of children’s purchases of TV advertised foods. The height and weight of children were measured. Logistic regression models were …

Health Care Disparities Around The Globe, Brianna N. Hodak, Renee Nicholson

Mountaineer Undergraduate Research Review

In Honduras, there are only 0.8 physicians for every 1,000 citizens, creating a nearly insurmountable barrier on the ability to access health care for the impoverished lower and middle classes. Various health care models that a country adopts directly affects the quality of life of its citizens, including access to care and clean water, advocacy of preventative methods, and life expectancy. By analyzing models, such as the “Out-of-Pocket”, Beveridge, and Bismarck models, one can see that there are positive and negative aspects in every system. It can also be seen that the American Healthcare system is also in dire need …

Association Between Stroke Health Literacy And Insurance With Stroke Severity And Post-Stroke Depression, Callista Clairmont, Amelia Adcock, Lea Colantonio

Mountaineer Undergraduate Research Review

Health literacy and insurance are important aspects of healthcare, yet few studies assess the roles that each play in relation to strokes. The purpose of this study is to better understand the relationship that stroke health literacy and insurance coverage have on the development of post-stroke outcomes such as post-stroke depression and stroke severity. In this study, 47 patients receiving inpatient care for acute ischemic stroke were given a modified version of the Stroke Knowledge Test in order to assess their understanding of strokes. Stroke severity and depression levels were also measured using the National Institute of Health Stroke Scale …

E2f6 Initiates Stable Epigenetic Silencing Of Germline Genes During Embryonic Development., Thomas Dahlet, Matthias Truss, Ute Frede, Hala Al Adhami, Anaïs F Bardet, Michael Dumas, Judith Vallet, Johana Chicher, Philippe Hammann, Sarah Kottnik, Peter Hansen, Uschi Luz, Gonzalo Alvarez, Ghislain Auclair, Jochen Hecht, Peter N Robinson, Christian Hagemeier, Michael Weber

Faculty Research 2021

In mouse development, long-term silencing by CpG island DNA methylation is specifically targeted to germline genes; however, the molecular mechanisms of this specificity remain unclear. Here, we demonstrate that the transcription factor E2F6, a member of the polycomb repressive complex 1.6 (PRC1.6), is critical to target and initiate epigenetic silencing at germline genes in early embryogenesis. Genome-wide, E2F6 binds preferentially to CpG islands in embryonic cells. E2F6 cooperates with MGA to silence a subgroup of germline genes in mouse embryonic stem cells and in embryos, a function that critically depends on the E2F6 marked box domain. Inactivation of E2f6 leads …

Covid-19 Treatment Combinations And Associations With Mortality In A Large Multi-Site Healthcare System., Dagan Coppock, Michael Baram, Anna Marie Chang, Patricia Henwood, Alan Kubey, Ross Summer, John Zurlo, Michael Li, Bryan Hess

Division of Infectious Diseases and Environmental Medicine Faculty Papers

INTRODUCTION: During the early months of the COVID-19 pandemic, mortality associated with the disease declined in the United States. The standard of care for pharmacological interventions evolved during this period as new and repurposed treatments were used alone and in combination. Though these medications have been studied individually, data are limited regarding the relative impact of different medication combinations. The objectives of this study were to evaluate the association of COVID-19-related mortality and observed medication combinations and to determine whether changes in medication-related practice patterns and measured patient characteristics, alone, explain the decline in mortality seen early in the COVID-19 …

Enhancing The Braden Scale Pressure Ulcer Risk Assessment In Long-Term Care Facilities: A Cohort Study, Rachel Deutsch

College of Science and Health Theses and Dissertations

The development of pressure ulcers remains challenging as they are associated with overwhelming costs, pain and suffering, prolonged hospitalization, and morbidity and mortality. In the United States, the Braden scale is the most widely used risk assessment tool among all healthcare organizations to identify high-risk individuals for pressure ulcer development. The objective of risk assessment is to detect high-risk patients, implement immediate interventions, and evaluate patients not at risk who do not require intervention. The purpose of this cohort study is to determine the pressure ulcer predictability of the Braden score in comparison to the Braden score with additional predictor …

Addressing Melanoma Risk In Families, Rebecca B. Roy, Deborah O. Himes

Student Works

Melanoma is one of the top 10 cancers in the United States. It is an aggressive and potentially fatal skin cancer. Up to 10% of all people diagnosed with melanoma have a positive family history of melanoma and a family history with a first degree relative can increase the risk for family members by 75%. Poor family communications often result in first degree relatives’ lack of knowledge about risk and prevention for melanoma. Considering this lack of knowledge, primary care providers have the opportunity to assess risk; teach and encourage prevention measures; teach and perform skin exams; and refer to …

Methods: A literature search was conducted in the MEDLINE, EMBASE, and CINAHL databases for all relevant literature on the …

Designer Benzodiazepines: A Review Of Toxicology And Public Health Risks, Pietro Brunetti, Raffaele Giorgetti, Adriano Tagliabracci, Marilyn A. Huestis, Francesco Paolo Busardò

Institute of Emerging Health Professions Faculty Papers

The rising use of designer benzodiazepines (DBZD) is a cat-and-mouse game between organized crime and law enforcement. Non-prohibited benzodiazepines are introduced onto the global drug market and scheduled as rapidly as possible by international authorities. In response, DBZD are continuously modified to avoid legal sanctions and drug seizures and generally to increase the abuse potential of the DBZD. This results in an unpredictable fluctuation between the appearance and disappearance of DBZD in the illicit market. Thirty-one DBZD were considered for review after consulting the international early warning database, but only 3-hydroxyphenazepam, adinazolam, clonazolam, etizolam, deschloroetizolam, diclazepam, flualprazolam, flubromazepam, flubromazolam, meclonazepam, …

Immune Cells In Lens Injury Repair And Fibrosis, Janice L Walker, A. Sue Menko

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Immune cells, both tissue resident immune cells and those immune cells recruited in response to wounding or degenerative conditions, are essential to both the maintenance and restoration of homeostasis in most tissues. These cells are typically provided to tissues by their closely associated vasculatures. However, the lens, like many of the tissues in the eye, are considered immune privileged sites because they have no associated vasculature. Such absence of immune cells was thought to protect the lens from inflammatory responses that would bring with them the danger of causing vision impairing opacities. However, it has now been shown, as occurs …

Polθ Reverse Transcribes Rna And Promotes Rna-Templated Dna Repair, Gurushankar Chandramouly, Jiemin Zhao, Shane Mcdevitt, Timur Rusanov, Trung Hoang, Nikita Borisonnik, Taylor Treddinick, Felicia Wednesday Lopezcolorado, Tatiana Kent, Labiba Siddique, Joseph Mallon, Jacklyn Huhn, Zainab Shoda, Ekaterina Kashkina, Alessandra Brambati, Jeremy M Stark, Xiaojiang S Chen, Richard Pomerantz

Department of Biochemistry and Molecular Biology Faculty Papers

Genome-embedded ribonucleotides arrest replicative DNA polymerases (Pols) and cause DNA breaks. Whether mammalian DNA repair Pols efficiently use template ribonucleotides and promote RNA-templated DNA repair synthesis remains unknown. We find that human Polθ reverse transcribes RNA, similar to retroviral reverse transcriptases (RTs). Polθ exhibits a significantly higher velocity and fidelity of deoxyribonucleotide incorporation on RNA versus DNA. The 3.2-Å crystal structure of Polθ on a DNA/RNA primer-template with bound deoxyribonucleotide reveals that the enzyme undergoes a major structural transformation within the thumb subdomain to accommodate A-form DNA/RNA and forms multiple hydrogen bonds with template ribose 2'-hydroxyl groups like retroviral RTs. …

Targeting The Apoa1 Locus For Liver-Directed Gene Therapy, Marco De Giorgi, Ang Li, Ayrea Hurley, Mercedes Barzi, Alexandria M Doerfler, Nikitha A Cherayil, Harrison E Smith, Jonathan D Brown, Charles Y Lin, Karl-Dimiter Bissig, Gang Bao, William R Lagor

Faculty, Staff and Students Publications

Clinical application of somatic genome editing requires therapeutics that are generalizable to a broad range of patients. Targeted insertion of promoterless transgenes can ensure that edits are permanent and broadly applicable while minimizing risks of off-target integration. In the liver, the Albumin (Alb) locus is currently the only well-characterized site for promoterless transgene insertion. Here, we target the Apoa1 locus with adeno-associated viral (AAV) delivery of CRISPR-Cas9 and achieve rates of 6% to 16% of targeted hepatocytes, with no evidence of toxicity. We further show that the endogenous Apoa1 promoter can drive robust and sustained expression of therapeutic …
