Introduction

• Control of the mitochondrial ATP production by SR-derived Ca2+ signals includes local, nanodomain Ca2+ transfer from ryanodine receptors (RyR2) to the mitochondrial matrix (excitation-bioenergetics coupling).

• Ca2+ crosses the inner mitochondrial membrane (IMM) via the mtCU, a low-affinity Ca2+-activated Ca2+ channel complex.

• The surface area of cardiac IMM is extensively enhanced by cristae folding; however, mitoplast patch clamp studies showed mtCU current density the lowest amongst a range of tissues (Fieni 2012. Nat Commun).

We report evidence of a novel pathogenetic mechanism in which thyroid hormone dysregulation contributes to dementia in elderly persons. Two single nucleotide polymorphisms (SNPs) on chromosome 12p12 were the initial foci of our study: rs704180 and rs73069071. These SNPs were identified by separate research groups as risk alleles for non-Alzheimer’s neurodegeneration. We found that the rs73069071 risk genotype was associated with hippocampal sclerosis (HS) pathology among people with the rs704180 risk genotype (National Alzheimer’s Coordinating Center/Alzheimer’s Disease Genetic Consortium data; n = 2113, including 241 autopsy-confirmed HS cases). Furthermore, both rs704180 and rs73069071 risk genotypes were associated with widespread brain …

A Novel Codon-Optimized Siv Gag-Pol Immunogen For Gene-Based Vaccination, Catherine M. Crosby, Eric A. Weaver, Reeti Khare, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

Simian immunodeficiency virus (SIV) is a robust pathogen used in non-human primates to model HIV vaccines. SIV encodes a number of potential vaccine targets. By far the largest and most conserved protein target in SIV is its gag-pol protein that bears many epitopes to drive multivalent immune T cell responses. While gag-pol is an attractive antigen, it is only translated after a frame shift between gag and pol with the effect that gag and pol are expressed at an approximate 10/1 ratio. The codon bias of native lentiviral genes are also mismatched with the abundance of tRNAs in mammalian cells …

Fulminant Necrotizing Eosinophilic Myocarditis: A Case Report And Comprehensive Literature Review, Bennet George, Matthew Hager, Virgilius Cornea, William O'Connor, Maya Guglin

The VAD Journal

Acute eosinophilic myocarditis is a relatively rare disorder with serious morbidity and mortality. Due to its infrequency, standardized management guidelines are wanting. We present a case of acute, necrotizing eosinophilic myocarditis requiring several levels of critical care. We reviewed similar cases reported in the literature to highlight common clinical features, describe natural disease course and associated complications, and review varying approaches to medical therapy.

Microtubules are dynamic cytoskeletal elements coordinating and supporting a variety of neuronal processes, including cell division, migration, polarity, intracellular trafficking, and signal transduction. Mutations in genes encoding tubulins and microtubule-associated proteins are known to cause neurodevelopmental and neurodegenerative disorders. Growing evidence suggests that altered microtubule dynamics may also underlie or contribute to neurodevelopmental disorders and neurodegeneration. We report that biallelic mutations in TBCD, encoding one of the five co-chaperones required for assembly and disassembly of the αβ-tubulin heterodimer, the structural unit of microtubules, cause a disease with neurodevelopmental and neurodegenerative features characterized by early-onset cortical atrophy, secondary hypomyelination, microcephaly, thin …

The Pathogenesis Of Natural Killer/T Cell Lymphoma, Bei Jiang

Theses & Dissertations

Extranodal natural killer/T-cell lymphomas (NKTCL) are uncommon lymphomas with poor prognosis. In order to gain a better understanding of the molecular pathogenesis of NKTCL, we obtained and compared the global gene expression profile, global somatic mutation profile, and global methylation profile of normal NK cells, malignant NK cell lines, and NKTCL patient samples. We showed that the JAK-STAT pathway was constitutively activated in NKTCL through the cooperation between activation of signal transducer and activator of transcription proteins (STATs) via activating mutations and inactivation of STAT suppressor protein suppressor of cytokine signaling 6 (SOCS6) through promoter hypermethylation. Activating STAT3 and STAT5B …

Activated Clotting Time (Act): Comparison Of The Hemochron Signature Elite And The Abbott I-Stat, Lilah Evans, Susanne Gallo, Joseph J. Leo, Barbara Goldsmith, Phd, Facb

Department of Pathology, Anatomy, and Cell Biology Posters

BACKGROUND

ACT is commonly used for heparin anticoagulation monitoring during procedures including cardiopulmonary bypass surgery, coronary angioplasty, and interventional radiology. To prevent thrombosis, moderate to high levels of heparin anticoagulation are required. The Hemochron Signature Elite (HSE, Accriva Diagnostics, formerly ITC, San Diego, CA) was implemented at TJUH as a replacement for the older model Hemochron Response (Accriva/ITC Model HRS.110, San Diego, CA). Operating room (OR) perfusionists reported irreproducible high results using HSE that could not be explained clinically. In consideration of use of i-STAT analyzers (Abbott Point of Care, Princeton, NJ) as an alternative to HSE, we performed a …

HCV and HIV independently lead to immune dysregulation. The mechanisms leading to advanced liver disease progression in HCV/HIV coinfected subjects remain unclear.

In this cross-sectional study, we assessed the association of HCV viremia, liver fibrosis, and immune response patterns in well-characterized HIV phenotypes: Elite controllers (Elites), HIV controlled (ARTc), and HIV uncontrolled (ARTuc) matched by age and race. Groups were stratified by HCV RNA status. Regulatory T-cell frequencies, T-cell activation (HLADR+CD38+), apoptosis (Caspase-3+), and intracellular cytokines (interferon-γ, IL-2, IL-17) were assessed using multiparametric flow-cytometry. Liver fibrosis was scored by AST to platelet ratio index (APRI).

We found liver fibrosis (APRI) …

INTRODUCTION: The relationship of diabetes to specific neuropathologic causes of dementia is incompletely understood.

METHODS: We used logistic regression to evaluate the association between diabetes and infarcts, Braak neurofibrillary tangle stage, and neuritic plaque score in 2365 autopsied persons. In a subset of >1300 persons with available cognitive data, we examined the association between diabetes and cognition using Poisson regression.

RESULTS: Diabetes increased odds of brain infarcts (odds ratio [OR] = 1.57, P < .0001), specifically lacunes (OR = 1.71, P < .0001), but not Alzheimer's disease neuropathology. Diabetes plus infarcts was associated with lower cognitive scores at end of life than infarcts or diabetes alone, and diabetes plus high level of Alzheimer's neuropathologic changes was associated with lower mini-mental state examination scores than the pathology alone.

DISCUSSION: This study supports the conclusions that diabetes increases the risk of cerebrovascular but not Alzheimer's disease pathology, and at least some of diabetes' relationship to …

Mucosal Vaccination By Adenoviruses Displaying Reovirus Sigma 1, Eric A. Weaver, Zenaido T. Camacho, Matthew L. Hillestad, Catherine M. Crosby, Mallory A. Turner, Adam J. Guenzel, Hind J. Fadel, George T. Mercier, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

We previously developed adenovirus serotype 5 (Ad5) vectors displaying the sigma 1 protein from reovirus as mucosal vaccines. Ad5-sigma retargets to JAM-1 and sialic acid, but had 40-fold reduced gene delivery when compared to Ad5. While weaker at transduction, Ad5-sigma generated stronger T cell responses than Ad5 when used for mucosal immunization. New Ad5-fiber-sigma vectors were generated here by varying the number of fiber β-spiral shaft repeats (R) fused between fiber tail and the sigma. Ad5 virions encoding R3, R14, and R20 chimeras were rescued. Increasing chimera length led to their decreasing encapsidation of these proteins in the virions. Ad5-R3 …

Human Herpesvirus Multiplex Ddpcr Detection In Brain Tissue From Low- And High-Grade Astrocytoma Cases And Controls., Cheng-Te Major Lin, Emily C Leibovitch, M Isabel Almira-Suarez, Steven Jacobson

Pathology Faculty Publications

BACKGROUND: Glioblastoma (GBM) is a fatal CNS malignancy, representing 50 % of all gliomas with approximately 12-18 months survival time after initial diagnosis. Recently, the human herpesvirus cytomegalovirus (CMV) has been suggested to have an oncogenic role, yet this association remains controversial. In addition, human herpesvirus 6 (HHV-6) and Epstein-Barr virus (EBV) have also been associated with low-grade gliomas, but few studies have examined HHV-6 and EBV in glioblastomas. Droplet digital PCR (ddPCR) is a highly precise diagnostic tool that enables the absolute quantification of target DNA. This study examines the association between multiple human herpesviruses and astrocytomas.

METHODS: This …

Malignant Hyperthermia, Aaron Roth

Nursing Student Class Projects (Formerly MSN)

Malignant hyperthermia is a rare disease trait and can take place in a variety of settings. If not treated in a timely manner, the consequences will be dire. It is recommended that nurses and other healthcare personnel be properly educated on MH crises. By detecting the signs and symptoms associated with the disease, providers can efficiently remedy the crisis and save patient lives (Seifert, 2014). Since the discovery of dantrolene in 1975 and the advancement of genetics regarding MH, death rates dropped from about 80% to about 5% (Schneiderbanger et al., 2014). Today there is a MH group called the …

Complex Regional Pain Syndrome, Maria A. Hendrix

Nursing Student Class Projects (Formerly MSN)

Complex regional pain syndrome (CRPS) is a chronic and often disabling condition that is seen in many patients seeking pain management. The condition leaves patients in excruciating pain that is disproportionate to the inciting injury. In addition, patients with this pain disorder experience abnormal sensations such as cold and heat allodynia, hyperalgesia, edema, abnormal sudomotor activity and trophic changes (D. Lee et al., 2015). CRPS disproportionally affects four times as many women as men (Alexander, Peterlin, Perreault, Grothusen, & Schwartzman, 2012). There are two types of CRPS: type 1, often referred to as reflex sympathetic dystrophy (RSD), is not evident …

Role Of Heme Oxygenase-1 In The Pathogenesis And Tumorigenicity Of Kaposi's Sarcoma-Associated Herpesvirus, Lu Dai, Jing Qiao, David Nguyen, Amanda P. Struckhoff, Lisa Doyle, Karlie Bonstaff, Luis Del Valle, Chris Parsons, Bryan P. Toole, Rolf Renne, Zhiqiang Qin

School of Medicine Faculty Publications

Kaposi's Sarcoma-associated Herpesvirus (KSHV) is the etiologic agent of several malignancies, including Kaposi's Sarcoma (KS), which preferentially arise in immunocompromised patients such as HIV+ subpopulation and lack effective therapeutic options. Heme oxygenase-1 (HO-1) has been reported as an important regulator of endothelial cell cycle control, proliferation and angiogenesis. HO-1 has also been found to be highly expressed in KSHV-infected endothelial cells and oral AIDS-KS lesions. We previously demonstrate that the multifunctional glycoprotein CD147 is required for KSHV/LANA-induced endothelial cell invasiveness. During the identification of CD147 controlled downstream genes by microarray analysis, we found that the expression of HO-1 is significantly …

Microrna Dysregulation And Esophageal Cancer Development Depend On The Extent Of Zinc Dietary Deficiency., Louise Fong, Cristian Taccioli, Ruiyan Jing, Karl Smalley, Hansjuerg Alder, Yubao Jiang, Paolo Fadda, John Farber, Carlo M Croce

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Zinc deficiency (ZD) increases the risk of esophageal squamous cell carcinoma (ESCC), and marginal ZD is prevalent in humans. In rats, marked-ZD (3 mg Zn/kg diet) induces a proliferative esophagus with a 5-microRNA signature (miR-31, -223, -21, -146b, -146a) and promotes ESCC. Here we report that moderate and mild-ZD (6 and 12 mg Zn/kg diet) also induced esophageal hyperplasia, albeit less pronounced than induced by marked-ZD, with a 2-microRNA signature (miR-31, -146a). On exposure to an environmental carcinogen, ~16% of moderate/mild-ZD rats developed ESCC, a cancer incidence significantly greater than for Zn-sufficient rats (0%) (P ≤ 0.05), but lower than …

Cd147 And Downstream Adamtss Promote The Tumorigenicity Of Kaposi's Sarcoma-Associated Herpesvirus Infected Endothelial Cells, Lu Dai, Jimena Trillo-Tinoco, Yihan Chen, Karlie Bonstaff, Luis Del Valle, Chris Parsons, Augusto C. Ochoa, Jovanny Zabaleta, Bryan P. Toole, Zhiqiang Qin

School of Medicine Faculty Publications

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent of several human cancers, including Kaposi's sarcoma (KS), which preferentially arise in immunocompromised patients and lack effective therapeutic options. We have previously shown that KSHV or viral protein LANA up-regulates the glycoprotein CD147, thereby inducing primary endothelial cell invasiveness. In the current study, we identify the global network controlled by CD147 in KSHV-infected endothelial cells using Illumina microarray analysis. Among downstream genes, two specific metalloproteases, ADAMTS1 and 9, are strongly expressed in AIDS-KS tissues and contribute to KSHV-infected endothelial cell invasiveness through up-regulation of IL-6 and VEGF. By using a KS-like nude …

Membranoproliferative Glomerulonephritis Recurrence After Kidney Transplantation: Using The New Classification., Sami Alasfar, Naima Carter-Monroe, Avi Z Rosenberg, Robert A Montgomery, Nada Alachkar

Pathology Faculty Publications

BACKGROUND: Membranoproliferative glomerulonephritis (MPGN) is an uncommon glomerular disorder that may lead to end stage renal disease (ESRD). With new understanding of the disease pathogenesis, the classical classification as MPGN types I, II, III has changed. Data on post-transplant MPGN, in particular with the newly refined classification, is limited. We present our center's experience of MPGN after kidney transplantation using the new classification.

METHODS: This is a retrospective study of 34 patients with ESRD due to MPGN who received 40 kidney transplants between 1994 and 2014. We reviewed the available biopsies' data using the new classification. We assessed post transplantation …

In-Silico Identification Of Prognostically Inversely Correlated Mirnas And Mrnas (Pic’S) In Multiple Cancers, Chirayu Pankaj Goswami, Zi-Xuan Wang

Department of Pathology, Anatomy, and Cell Biology Posters

Despite numerous methods available to identify potential mRNA targets for miRNAs, prognostic relationship of these molecules in diseases like cancers where deregulation of gene expression is a major pathogenic factor, has not yet been emphasized. We performed in-silico identification of prognostically inversely correlated miRNA - mRNA pairs (PIC’s) in multiple cancers using expression data from The Cancer Genome Atlas. Partners in a PIC show inverse correlation of expression and opposite hazard implication. Using a three step approach, we identified a total of 1,253,443 PIC’s from 23 cancer types, several of which have previously been shown to have a predicted or …

Non-Alcoholic Fatty Liver Disease Induces Signs Of Alzheimer’S Disease (Ad) In Wild-Type Mice And Accelerates Pathological Signs Of Ad In An Ad Model, Do-Geun Kim, Antje Krenz, Leon E. Toussaint, Kirk J. Maurer

Dartmouth Scholarship

Background: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease afflicting about one third of the world's population and 30 % of the US population. It is induced by consumption of high-lipid diets and is characterized by liver inflammation and subsequent liver pathology. Obesity and consumption of a high-fat diet are known to increase the risk of Alzheimer's disease (AD). Here, we investigated NAFLD-induced liver inflammation in the pathogenesis of AD.

Methods: WT and APP-Tg mice were fed with a standard diet (SD) or a high-fat diet (HFD) for 2, 5 months, or 1 year to induce NAFLD. Another …
