Ryanodine Receptor 1-Related Disorders: An Historical Perspective And Proposal For A Unified Nomenclature, Tokunbor A Lawal, Joshua J Todd, Jessica W Witherspoon, Carsten G Bönnemann, James J Dowling, Susan L Hamilton, Katherine G Meilleur, Robert T Dirksen

Faculty, Staff and Students Publications

The RYR1 gene, which encodes the sarcoplasmic reticulum calcium release channel or type 1 ryanodine receptor (RyR1) of skeletal muscle, was sequenced in 1988 and RYR1 variations that impair calcium homeostasis and increase susceptibility to malignant hyperthermia were first identified in 1991. Since then, RYR1-related myopathies (RYR1-RM) have been described as rare, histopathologically and clinically heterogeneous, and slowly progressive neuromuscular disorders. RYR1 variants can lead to dysfunctional RyR1-mediated calcium release, malignant hyperthermia susceptibility, elevated oxidative stress, deleterious post-translational modifications, and decreased RyR1 expression. RYR1-RM-affected individuals can present with delayed motor milestones, contractures, scoliosis, ophthalmoplegia, and respiratory insufficiency.Historically, RYR1-RM-affected individuals were …

Publications and Research

The coronavirus disease 19 (COVID-19) pandemic has resulted in the urgent need to develop and deploy treatment approaches that can minimize mortality and morbidity. As infection, resulting illness, and the often prolonged recovery period continue to be characterized, therapeutic roles for transcranial electrical stimulation (tES) have emerged as promising non-pharmacological interventions. tES techniques have established therapeutic potential for managing a range of conditions relevant to COVID-19 illness and recovery, and may further be relevant for the general management of increased mental health problems during this time. Furthermore, these tES techniques can be inexpensive, portable, and allow for trained self-administration. Here, …

Evaluation Of Aging And Genetic Mutation Variants On Tauopathy, Amber M. Tetlow

USF Tampa Graduate Theses and Dissertations

Alzheimer’s disease (AD) is characterized by amyloid β plaques and neurofibrillary tau tangles (NFTs). While research has demonstrated amyloid pathology occurs prior to tau pathology, or tauopathy, tau has proven to be more toxic. Tauopathy is associated with cognitive declines and neurodegeneration. These findings have highlighted the importance of further understanding tauopathy. In the progression of tauopathy, there is an observable immune response that can be measured by glial cells such as microglia. Activated microglia are known to exacerbate tauopathy rather than reducing the pathology. Research has indicated that with increased age there is an increased risk for AD-related tauopathy …

Structural Basis Of Ion Transport And Inhibition In Ferroportin, Yaping Pan, Zhenning Ren, Shuai Gao, Jiemin Shen, Lie Wang, Zhichun Xu, Ye Yu, Preetham Bachina, Hanzhi Zhang, Xiao Fan, Arthur Laganowsky, Nieng Yan, Ming Zhou

Faculty, Staff and Students Publications

Ferroportin is an iron exporter essential for releasing cellular iron into circulation. Ferroportin is inhibited by a peptide hormone, hepcidin. In humans, mutations in ferroportin lead to ferroportin diseases that are often associated with accumulation of iron in macrophages and symptoms of iron deficiency anemia. Here we present the structures of the ferroportin from the primate Philippine tarsier (TsFpn) in the presence and absence of hepcidin solved by cryo-electron microscopy. TsFpn is composed of two domains resembling a clamshell and the structure defines two metal ion binding sites, one in each domain. Both structures are in an outward-facing conformation, and …

Ceramide Analog [18F]F-Hpa-12 Detects Sphingolipid Disbalance In The Brain Of Alzheimer’S Disease Transgenic Mice By Functioning As A Metabolic Probe, Simone M.

The metabolism of ceramides is deregulated in the brain of Alzheimer’s disease (AD) patients and is associated with apolipoprotein (APO) APOE4 and amyloid-β pathology. However, how the ceramide metabolism changes over time in AD, in vivo, remains unknown. Distribution and metabolism of [¹⁸F]F-HPA-12, a radio-fluorinated version of the ceramide analog N-(3-hydroxy-1-hydroxymethyl-3-phenylpropyl) dodecanamide, was investigated in the brain of AD transgenic mouse models (FAD) on an APOE4 or APOE3 genetic background, by positron emission tomography and by gamma counter. We found that FAD mice displayed a higher uptake of [¹⁸F]F-HPA-12 in the brain, independently from the APOE4 …

Young Versus Aged Microbiota Transplants To Germ-Free Mice: Increased Short-Chain Fatty Acids And Improved Cognitive Performance, Juneyoung Lee, Venugopal R Venna, David J Durgan, Huanan Shi, Jacob Hudobenko, Nagireddy Putluri, Joseph Petrosino, Louise D Mccullough, Robert M Bryan

Faculty, Staff and Students Publications

Aging is associated with cognitive decline and decreased concentrations of short-chain fatty acids (SCFAs) in the gut. SCFAs are significant in that they are protective to the gut and other organs. We tested the hypothesis that the aged gut microbiome alone is sufficient to decrease SCFAs in the host and produce cognitive decline. Fecal transplant gavages (FTGs) from aged (18–20 months) or young (2–3 months) male C57BL/6 mice into germ-free male C57BL/6 mice (N = 11 per group) were initiated at ~3 months of age. Fecal samples were collected and behavioral testing was performed over the study period. Bacterial community …

Department of Paediatrics and Child Health

Background: Simulators are an extensively utilized teaching tool in clinical settings. Simulation enables learners to practice and improve their skills in a safe and controlled environment before using these skills on patients. We evaluated the effect of a training session utilizing a novel intubation ultrasound simulator on the accuracy of provider detection of tracheal versus esophageal neonatal endotracheal tube (ETT) placement using point-of-care ultrasound (POCUS). We also investigated whether the time to POCUS image interpretation decreased with repeated simulator attempts.
Methods: Sixty neonatal health care providers participated in a three-hour simulator-based training session in the neonatal intensive care unit (NICU) …

Loss Of Class Iii Phosphoinositide 3-Kinase Vps34 Results In Cone Degeneration, Ammaji Rajala, Feng He, Robert E Anderson, Theodore G Wensel, Raju V S Rajala

Faculty, Staff and Students Publications

The major pathway for the production of the low-abundance membrane lipid phosphatidylinositol 3-phosphate (PI(3)P) synthesis is catalyzed by class III phosphoinositide 3-kinase (PI3K) Vps34. The absence of Vps34 was previously found to disrupt autophagy and other membrane-trafficking pathways in some sensory neurons, but the roles of phosphatidylinositol 3-phosphate and Vps34 in cone photoreceptor cells have not previously been explored. We found that the deletion of Vps34 in neighboring rods in mouse retina did not disrupt cone function up to 8 weeks after birth, despite diminished rod function. Immunoblotting and lipid analysis of cones isolated from the cone-dominant retinas of the …

Although TP53 is the most commonly mutated gene in human cancers, the p53-dependent transcriptional programs mediating tumor suppression remain incompletely understood. Here, to uncover critical components downstream of p53 in tumor suppression, we perform unbiased RNAi and CRISPR-Cas9-based genetic screens in vivo. These screens converge upon the p53-inducible gene Zmat3, encoding an RNA-binding protein, and we demonstrate that ZMAT3 is an important tumor suppressor downstream of p53 in mouse Kras

On October 13, 2020 Facebook announced the adoption of a series of measures to promote vaccine trust “while prohibiting ads with misinformation that could harm public health efforts.” In the post written by Kang-Xing Jin (head of health) and Rob Leathern (director of product management), the company explained that the new measures were designed with an emphasis on encouraging widespread use of this yearʼs flu vaccine, as well as in anticipation of potential COVID-19 vaccines becoming available in the near future.

The changes focus mainly on the establishment of a multiprong informational campaign about the seasonal flu vaccine, which includes …

Neutrophil-To-Lymphocyte Ratio: A Biomarker To Monitor The Immune Status Of Astronauts, Amber M. Paul, Siddhita D. Mhatre, Egle Cekanaviciute, Ann-Sofie Schreurs, Candice G.T. Tahimic, Ruth K. Globus, Sulekha Anand, Brian E. Crucian, Sharmila Bhattacharya

Publications

A comprehensive understanding of spaceflight factors involved in immune dysfunction and the evaluation of biomarkers to assess in-flight astronaut health are essential goals for NASA. An elevated neutrophil-to-lymphocyte ratio (NLR) is a potential biomarker candidate, as leukocyte differentials are altered during spaceflight. In the reduced gravity environment of space, rodents and astronauts displayed elevated NLR and granulocyte-to-lymphocyte ratios (GLR), respectively. To simulate microgravity using two well-established ground-based models, we cultured human whole blood-leukocytes in high-aspect rotating wall vessels (HARV-RWV) and used hindlimb unloaded (HU) mice. Both HARV-RWV simulation of leukocytes and HU-exposed mice showed elevated NLR profiles comparable to spaceflight …

Modulation Of Ros In Nanosecond-Pulsed Plasma-Activated Media For Dosage-Dependent Cancer Cell Inactivation In Vitro, Chunqi Jiang, Esin Bengisu Sozer, Shutong Song, Nicola Lai, P. Thomas Vernier, Sigi Guo

Bioelectrics Publications

Dosage control of reactive oxygen and nitrogen species (RONS) is critical to low-temperature plasma applications in cancer therapy. Production of RONS by atmospheric pressure, nonequilibrium plasmas in contact with liquid may be modulated via plasma conditions including plasma treatment time and pulse voltage and repetition frequency. In this study, a terephthalic acid-based probe was used to measure hydroxyl radicals [OH_aq] in water exposed to plasma and to demonstrate that the OH_ag concentration increases linearly with treatment time. Fluorometric measurements of hydrogen peroxide concentration in plasma-activated water show a linear relationship between the H₂O₂ production …

Children’s Nutrition Research Center Staff Publications

metabolism of citrulline and arginine are well characterized. Enteroids, a novel ex-vivo model that recreates the three-dimensional structure of the intestinal crypt-villus unit, have shown to replicate molecular and physiological profiles of the intestinal segment from where they originated ("location memory").

Objective: The present study tested the hypothesis that enteroids recapitulate the developmental changes observed in vivo regarding citrulline production in pigs ("developmental memory").

Methods: Preterm (10- and 5-d preterm) and term pigs at birth, together with 7- and 35-d-old pigs were studied. Gene expression was measured in jejunal samples and in enteroids derived from this segment. Whole body citrulline …

Β-Cell Impairment And Clinically Meaningful Alterations In Glycemia In Obese Youth Across The Glucose Tolerance Spectrum, Joon Young Kim, Hala Tfayli, Fida Bacha, Sojung Lee, Nour Gebara, Silva Arslanian

Children’s Nutrition Research Center Staff Publications

Background/aims: In obese youth, it is not clear what degree of β-cell impairment translates to glucose dysregulation commensurate with shifts from normal glucose tolerance (NGT) to impaired glucose tolerance (IGT) to type 2 diabetes. We aimed to investigate the quantitative relationship between β-cell (clamp-measured disposition index [DI]) and OGTT glucose area under the curve (G-AUC) in obese youth across the spectrum of glucose tolerance.

Methods: Data from 152 youth (58 African-American [AA] and 94 American-White [AW]; 73 NGT, 48 IGT, and 31 type 2 diabetes) who completed a 3-h hyperinsulinemic (80 mu/m2/min)-euglycemic clamp, and a 2-h hyperglycemic (225 mg/dL) clamp …

Variable Expression Of Msh6 In Endometrial Carcinomas With Intact Mismatch Repair And With Mlh1 Loss Due To Mlh1 Methylation, Nidhi Tandon, Courtney Hudgens, Bryan Fellman, Michael T Tetzlaff, Russell R Broaddus

Faculty, Staff and Student Publications

Immunohistochemistry for mismatch repair proteins MLH1, MSH2, MSH6, and PMS2 is an effective screen to detect individuals at risk for Lynch syndrome. College of American Pathologists guidelines stipulate that protein expression should be reported as present versus absent, as most patients with germline mutations in a mismatch repair gene have complete loss of protein expression in tumor cells. A similar approach is employed to screen for cancer patients eligible for immune checkpoint blockade. This "all or none" interpretive approach ignores substantial evidence that mismatch repair may be more finely regulated by other mechanisms. We have observed clinically that MSH6 expression …

Identification Of Novel Candidate Risk Genes For Myelomeningocele Within The Glucose Homeostasis/Oxidative Stress And Folate/One-Carbon Metabolism Networks, Paul Hillman, Craig Baker, Luke Hebert, Michael Brown, James Hixson, Allison Ashley-Koch, Alanna C Morrison, Hope Northrup, Kit Sing Au

Faculty, Staff and Student Publications

BACKGROUND: Neural tube defects (NTDs) are the second most common complex birth defect, yet, our understanding of the genetic contribution to their development remains incomplete. Two environmental factors associated with NTDs are Folate and One Carbon Metabolism (FOCM) and Glucose Homeostasis and Oxidative Stress (GHOS). Utilizing next-generation sequencing of a large patient cohort, we identify novel candidate genes in these two networks to provide insights into NTD mechanisms.

METHODS: Exome sequencing (ES) was performed in 511 patients, born with myelomeningocele, divided between European American and Mexican American ethnicities. Healthy control data from the Genome Aggregation database were ethnically matched and …

Vitamin D Levels Affect Survival In A Bcr-Abl Acute Lymphoblastic Leukemia Mouse Model But Do Not Cause Vitamin-Drug Interactions, Kavya Annu

Theses and Dissertations (ETD)

It is a well-established phenomenon that dietary components containing CYP3A inducers or inhibitors if co-administered with drugs that are CYP3A4 substrates lead to marked drug-drug interactions. Because vitamin D is known to regulate intestinal CYP3A expression and gut CYP3A expression plays an important role in pre-systemic metabolism of CYP3A drugs, we determined the impact of vitamin D (VD3) status on systemic exposure and efficacy of chemotherapeutic agents that are CYP3A substrates. We employed VD3 sufficient and deficient mice to perform pharmacokinetics (PK) and anti-leukemic efficacy studies.

First, using hCYP3A4 transgenic mouse model we evaluated the intestinal, hepatic and renal expression …

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), a novel coronavirus responsible for a worldwide pandemic has forced drastic changes in medical practice in an alarmingly short period of time. Caregivers must modify their strategies as well as optimize the utilization of resources to ensure public and patient safety. For organ transplantation, in particular, the loss of lifesaving organs for transplantation could lead to increased waitlist mortality. The priority is to select uninfected donors to transplant uninfected recipients while maintaining safety for health care systems in the backdrop of a virulent pandemic. We do not yet have a standard approach to evaluating …

Pr Depression With Multilead St Elevation And St Depression In Avr By Left Circumflex Artery Occlusion: How To Differentiate From Acute Pericarditis, Zhong-Qun Zhan, Kjell Nikus, Yochai Birnbaum

Faculty, Staff and Students Publications

PR-segment depression with multilead ST-segment elevation and ST-segment depression in lead aVR are classic ECG manifestation of acute pericarditis. We present a patient, where the etiology of these ECG features was acute ST-elevation myocardial infarction due to left circumflex artery occlusion. To avoid misdiagnosis, unnecessary examinations, and inappropriate therapeutic decisions, the possibility of ST-segment elevation myocardial infarction should be kept in mind even when ECG changes typical for pericarditis are encountered in chest pain patients. Findings of QRS widening and QT interval shortening in leads with ST-segment elevation could help to differentiate acute ST-segment elevation myocardial infarction from acute pericarditis.

An 11-year-old female with a congenitally malformed left hand, sickle-cell trait, asthma, and history of appendicitis was transferred from Zambia for evaluation and treatment of widespread suppurative and ulcerative skin lesions that typically appeared following trauma to her skin. The ulcers first presented 3 years earlier but had markedly worsened in the 9 months prior to transfer, spreading circumferentially on her extremities and abdomen at the site of an appendectomy. They were painful and did not resolve with multiple courses of intravenous (IV) antibiotics and close management by a Pediatric Infectious Disease specialist working for a non-governmental organization (NGO) in …

Genetics Of Smoking Behaviors In American Indians, Jeffrey A Henderson, Dedra S Buchwald, Barbara V Howard, Patricia Nez Henderson, Yafang Li, Rachel F Tyndale, Christopher I Amos, Olga Y Gorlova, Collaborative To Improve Native Cancer Outcomes (Cinco), A P50 Center For Population Health And Health Disparities Program Project Sponsored By The National Cancer Institute

Faculty, Staff and Students Publications

BACKGROUND: The smoking behavior of American Indians (AI) differs from that of non-Hispanic whites (NHW). Typically light smokers, cessation interventions in AIs are generally less effective. To develop more effective cessation programs for AIs, clinicians, researchers, and public health workers need a better understanding of the genetic factors involved in their smoking behavior. Our aim was to assess whether SNPs associated with smoking behavior in NHWs are also associated with smoking in AIs.

METHODS: We collected questionnaire data on smoking behaviors and analyzed blood and saliva samples from two Tribal populations with dramatically different cultures and smoking prevalence, one in …

RESULTS: One hundred four surveys were completed (response rate = 69.3%). Overall, the evidence subscale had the highest score; the resources subscale (mean 2.8) was …

Perampanel-Induced Cataplexy In A Young Male With Generalized Epilepsy, Kelsey Kenaan, Mohsin Zafar, Ronnie Bond, Barbara L. Gracious

HCA Healthcare Journal of Medicine

Perampanel (Fycompa) is a newer anti-epileptic drug believed to exert its effects in the central nervous system by inhibiting post-synaptic glutamate receptors. However, the precise therapeutic mechanism is unknown. The most common neuropsychiatric side effect is affective dysregulation; there are also reports of psychosis. We describe a 32 year old African American male with recurring generalized tonic-clonic (GTC) seizures, who presented to our hospital with onset of mood lability for several months, after Perampanel was added to his antiepileptic medications. Perampanel administration was temporarily withheld, and subsequently on restarting, noted to be coincident with neuropsychiatric symptomatology, including motor weakness in …

Microrna-Based Biomarkers In Alzheimer’S Disease (Ad), Yuhai Zhao, Vivian Jaber, Peter N. Alexandrov, Andrea Vergallo, Simone Lista, Harald Hampel, Walter J. Lukiw

School of Medicine Faculty Publications

Alzheimer’s disease (AD) is a multifactorial, age-related neurological disease characterized by complex pathophysiological dynamics taking place at multiple biological levels, including molecular, genetic, epigenetic, cellular and large-scale brain networks. These alterations account for multiple pathophysiological mechanisms such as brain protein accumulation, neuroinflammatory/neuro-immune processes, synaptic dysfunction, and neurodegeneration that eventually lead to cognitive and behavioral decline. Alterations in microRNA (miRNA) signaling have been implicated in the epigenetics and molecular genetics of all neurobiological processes associated with AD pathophysiology. These changes encompass altered miRNA abundance, speciation and complexity in anatomical regions of the CNS targeted by the disease, including modified miRNA expression …
