AIMS: Mitochondrial Ca2+ homeostasis is crucial for balancing cell survival and death. The recent discovery of the molecular identity of the mitochondrial Ca2+ uniporter pore (MCU) opens new possibilities for applying genetic approaches to study mitochondrial Ca2+ regulation in various cell types, including cardiac myocytes. Basal tyrosine phosphorylation of MCU was reported from mass spectroscopy of human and mouse tissues, but the signaling pathways that regulate mitochondrial Ca2+ entry through posttranslational modifications of MCU are completely unknown. Therefore, we investigated α1-adrenergic-mediated signal transduction of MCU posttranslational modification and function in cardiac cells.

RESULTS: α1-adrenoceptor (α1-AR) signaling translocated activated proline-rich tyrosine …

Vascular Architecture Of The Liver In Shr And Wky Rats, Charalette Mathwig, Kenneth Willaert

Journal of Undergraduate Research at Minnesota State University, Mankato

The liver is a highly complex vascular organ containing an intricate network of arteries, arterioles, portal veins, veins, venules, and capillaries. This complex network could change in situations related to vascular disease such as hypertension. We examined the vasculature in rat livers by scanning electron microscopy. The tissue was prepared by perfusing either Mercox resin or polyurethane resin into the vasculature. Once the resin polymerized, each liver was placed in concentrated potassium hydroxide to corrode the tissue from the vascular casts. The casts were critical point dried, sputter coated with gold-palladium, and viewed by scanning electron microscopy. Examination of the …

Generation And Behavior Characterization Of Camkiiβ Knockout Mice, Adam D. Bachstetter, Scott J. Webster, Tao Tu, Danielle S. Goulding, Jacques Haiech, D. Martin Watterson, Linda J. Van Eldik

Sanders-Brown Center on Aging Faculty Publications

The calcium/calmodulin-dependent protein kinase II (CaMKII) is abundant in the brain, where it makes important contributions to synaptic organization and homeostasis, including playing an essential role in synaptic plasticity and memory. Four genes encode isoforms of CaMKII (α, β, δ, γ), with CaMKIIα and CaMKIIβ highly expressed in the brain. Decades of molecular and cellular research, as well as the use of a large number of CaMKIIα mutant mouse lines, have provided insight into the pivotal roles of CaMKIIα in brain plasticity and cognition. However, less is known about the CaMKIIβ isoform. We report the development and extensive behavioral and …

Loss Of 4e-Bp1 Function Induces Emt And Promotes Cancer Cell Migration And Invasion Via Cap-Dependent Translational Activation Of Snail, Weijia Cai, Qing Ye, Qing-Bai She

Markey Cancer Center Faculty Publications

The cap-dependent translation is frequently deregulated in a variety of cancers associated with tumor progression. However, the molecular basis of the translation activation for metastatic progression of cancer remains largely elusive. Here, we demonstrate that activation of cap-dependent translation by silencing the translational repressor 4E-BP1 causes cancer epithelial cells to undergo epithelial-mesenchymal transition (EMT), which is associated with selective upregulation of the EMT inducer Snail followed by repression of E-cadherin expression and promotion of cell migratory and invasive capabilities as well as metastasis. Conversely, inhibition of cap-dependent translation by a dominant active mutant 4E-BP1 effectively downregulates Snail expression and suppresses …

An Overview Of Cancer Rehabilitation And Exercise In The Literature: Promoting Increased Referrals To Improve Oncology Outcomes, Leslie J. Waltke

Journal of Patient-Centered Research and Reviews

Medical management for malignant neoplastic diseases includes surgery, chemotherapy, radiation, and hormonal and biological therapies. Each of these antineoplastic interventions has unique impacts on physiological, musculoskeletal and functional performance. Cancer rehabilitation is the area of physical medicine responsible for addressing impairments associated with cancer treatment and survivorship, advanced disease and end of life. Although it is expected that more than one-half of persons being treated for cancer will suffer moderate pain and physical and functional decline, and that most will describe fatigue, referrals to rehabilitation are traditionally low. Evidence suggests that referrals to rehabilitation before, during and after treatment for …

Epoxide-Mediated Differential Packaging Of Cif And Other Virulence Factors Into Outer Membrane Vesicles, A. E. Ballok, L. M. Filkins, J.. M. Bomberger, B. A. Stanton, George A. O'Toole

Dartmouth Scholarship

Pseudomonas aeruginosa produces outer membrane vesicles (OMVs) that contain a number of secreted bacterial proteins, including phospholipases, alkaline phosphatase, and the CFTR inhibitory factor (Cif). Previously, Cif, an epoxide hydrolase, was shown to be regulated at the transcriptional level by epoxides, which serve as ligands of the repressor, CifR. Here, we tested whether epoxides have an effect on Cif levels in OMVs. We showed that growth of P. aeruginosa in the presence of specific epoxi

The Role Of Ape/Ref-1 In Hepatocellular Carcinoma Progression, Zhen Yang, Sun Yang, Bobbye J. Misner, Feng Liu-Smith, Frank L. Meyskens

Pharmacy Faculty Articles and Research

Hepatocellular carcinoma (HCC) is responsible for a third of the estimated cancer-caused deaths worldwide. To deeply understand the mechanisms controlling HCC progression is of primary importance to develop new approaches for treatment. Apurinic/apyrimidinic endonuclease-1/redox effector factor 1 (APE/Ref-1) has been uncovered elevated in various types of cancer, including HCC. Additionally, HCC progression is always correlated with elevated copper (Cu). Our previous data demonstrated that Cu treatment initiated APE/Ref-1 expression and its downstream targets. Therefore, we hypothesized that APE/Ref-1 may be involved in HCC progression through mediating the effect of Cu to its signaling cascades. Following different treatments, human HCC cell …

The Influence Of Race/Ethnicity And Place Of Service On Breast Reconstruction For Medicare Beneficiaries With Mastectomy, Tracy Onega, Julie Weiss, Karla Kerlikowske, Karen Wernli

Dartmouth Scholarship

Racial disparities in breast reconstruction for breast cancer are documented. Place of service has contributed to disparities in cancer care; but the interaction of race/ethnicity and place of service has not been explicitly examined. We examined whether place of service modified the effect of race/ethnicity on receipt of reconstruction. We included women with a mastectomy for incident breast cancer in SEER-Medicare from 2005-2009. Using Medicare claims, we determined breast reconstruction within 6 months. Facility characteristics included: rural/urban location, teaching status, NCI Cancer Center designation, cooperative oncology group membership, Disproportionate Share Hospital (DSH) status, and breast surgery volume. Using multivariable logistic …

Safety And Immunogenicity Of Human Serum Albumin-Free Mmr Vaccine In Us Children Aged 12–15 Months, Maurice A. Mufson, Clemente Diaz, Michael Leonardi, Christopher J. Harrison, Stanley Grogg, Antonio Carbayo, Simon Carlo-Torres, Robert Jean Freau, Ana Quintero-Del-Rio, Gisele Bautista, Michael Povey, Christopher Da Costa, Ouzama Nicholson, Bruce L. Innis

Internal Medicine

Background: M-M-RTMII (MMRII; Merck & Co) is currently the only measles-mumps-rubella (MMR) vaccine licensed in the United States. Another licensed vaccine would reinforce MMR supply. This study assessed the immunogenicity of a candidate vaccine (PriorixTM, GlaxoSmithKline Vaccines [MMR-RIT]) when used as a first dose among eligible children in the United States.

Methods: In this exploratory Phase-2, multicenter, observer-blind study, 1220 healthy subjects aged 12–15 months were randomized (3:3:3:3) and received 1 dose of 1 of 3 MMR-RIT lots with differing mumps virus titers (MMR-RIT-1 [4.8 log10]; MMR-RIT-2 [4.1 log10]; MMR-RIT-3 [3.7 log10] CCID50) or MMRII co-administered with hepatitis Avaccine (HAV), …

Appropriate Development Of The Liver Treg Compartment Is Modulated By The Microbiota And Requires Tgf-Β And Myd88, Ann Maria, Kathryn A. English, James D. Gorham

Dartmouth Scholarship

Neither the early postnatal development of the liver Treg compartment nor the factors that regulate its development has been characterized. We compared the early developmental patterns of Treg cell accumulation in murine liver, thymus, and spleen. A FoxP3EGFP reporter mouse was employed to identify Treg cells. Mononuclear cells were isolated from organs postnatally, stained for CD4, and examined by flow cytometry to enumerate FoxP3+CD4hi cells. To assess roles for TGF-��1, MyD88, and TLR2, gene specific knockout pups were generated from heterozygous breeders. To test the role of commensal bacteria, pregnant dams were administered antibiotics during gestation and after parturition.The pattern …

Identification Of Functional Parameters For The Classification Of Older Female Fallers And Prediction Of ‘First-Time’ Fallers, Niklas König Ignasiak

Physical Therapy Faculty Articles and Research

Falls remain a challenge for ageing societies. Strong evidence indicates that a previous fall is the strongest single screening indicator for a subsequent fall and the need for assessing fall risk without accounting for fall history is therefore imperative. Testing in three functional domains (using a total 92 measures) were completed in 84 older women (60–85 years of age), including muscular control, standing balance, and mean and variability of gait. Participants were retrospectively classified as fallers (n = 38) or non-fallers (n = 42) and additionally in a prospective manner to identify first-time fallers (FTFs) (n = 6) within a …

Imaging Luciferase-Expressing Viruses, Michael A. Barry, Shannon May, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Optical imaging of luciferage gene expression has become a powerful tool to track cells and viruses in vivo in small animal models. Luciferase imaging has been used to study the location of infection by replication-defective and replication-competent viruses and to track changes in the distribution of viruses in mouse models. This approach has also been used in oncolytic studies as a non-invasive means to monitor the growth and killing of tumor cells modified with luciferase genes. In this chapter, we describe the techniques used for luciferase imaging as have been applied to track replication-defective and replication-competent adenoviruses in mouse and …

Blau Syndrome, The Prototypic Auto-Inflammatory Granulomatous Disease., Carine H Wouters, Anne Maes, Kevin P Foley, John Bertin, Carlos D Rose

Department of Medicine Faculty Papers

Blau syndrome is a monogenic disease resulting from mutations in the pattern recognition receptor NOD2, and is phenotypically characterized by the triad of granulomatous polyarthritis, dermatitis and uveitis. This paper reviews briefly the classical clinical features of the disease, as well as more recently described extra-triad symptoms. From an ongoing prospective multicenter study, we provide new data on the natural history of Blau syndrome, focusing on functional status and visual outcome. We also present an update of the range of different NOD2 mutations found in Blau syndrome as well as recent data on morphologic and immunohistochemical characteristics of the Blau …

Clinical And Biochemical Function Of Polymorphic Nr0b1 Ggaa-Microsatellites In Ewing Sarcoma: A Report From The Children's Oncology Group., Michael J. Monument, Kirsten M. Johnson, Elizabeth Mcilvaine, Lisa Abegglen, W. Scott Watkins, Lynn B. Jorde, Richard B. Womer, Natalie Beeler, Laura Monovich, Elizabeth R. Lawlor, Julia A. Bridge, Joshua D. Schiffman, Mark D Krailo, R. Lor Randall, Stephen L. Lessnick

Journal Articles: Pathology and Microbiology

BACKGROUND: The genetics involved in Ewing sarcoma susceptibility and prognosis are poorly understood. EWS/FLI and related EWS/ETS chimeras upregulate numerous gene targets via promoter-based GGAA-microsatellite response elements. These microsatellites are highly polymorphic in humans, and preliminary evidence suggests EWS/FLI-mediated gene expression is highly dependent on the number of GGAA motifs within the microsatellite.

OBJECTIVES: Here we sought to examine the polymorphic spectrum of a GGAA-microsatellite within the NR0B1 promoter (a critical EWS/FLI target) in primary Ewing sarcoma tumors, and characterize how this polymorphism influences gene expression and clinical outcomes.

RESULTS: A complex, bimodal pattern of EWS/FLI-mediated gene expression was observed …

Somatic Intronic Microsatellite Loci Differentiate Glioblastoma From Lower-Grade Gliomas, Enusha Karunasena, Lauren J. Mciver, Brian R. Rood, Xiaowei Wu, Hongxiao Zhu, Jasmin H. Bavarva, Harold R. Garner

Pediatrics Faculty Publications

Genomic studies of glioma sub-types have amassed new disease specific mutations, yet these only partially explain how mutations are linked to predisposition or progression. We hypothesized that microsatellite variation could expand the understanding of glioma etiology. Furthermore, germline markers for gliomas are typically undetectable; therefore we also hypothesize that the predictability of cancer-associated microsatellite loci in germline DNA may support the current hypothesis of a glioma cell of origin.

In this study, “normal” germline exome sequenced DNA from the 1000 Genomes Project (n=390) were compared with exome sequences from germlines of subjects with WHO grade II and III lower-grade glioma …

Breach Of Tolerance: Primary Biliary Cirrhosis., Lifeng Wang, Fu-Sheng Wang, Christopher Chang, M Eric Gershwin

Department of Medical Genetics Faculty Papers

In primary biliary cirrhosis (PBC), the breach of tolerance that leads to active disease involves a disruption in several layers of control, including central tolerance, peripheral anergy, a "liver tolerance effect," and the action of T regulatory cells and their related cytokines. Each of these control mechanisms plays a role in preventing an immune response against self, but all of them act in concert to generate effective protection against autoimmunity without compromising the ability of the host immune system to mount an effective response to pathogens. At the same time, genetic susceptibility, environmental factors, including infection agents and xenobiotics, play …

Towards Image-Guided Pediatric Atrial Septal Defect Repair, Fuad Mefleh

All Dissertations

Congenital heart disease occurs in 107.6 out of 10,000 live births, with Atrial Septal Defects (ASD) accounting for 10\% of these conditions. Historically, ASDs were treated with open heart surgery using cardiopulmonary bypass, allowing a patch to be sewn over the defect. In 1976, King et al. demonstrated use of a transcatheter occlusion procedure, thus reducing the invasiveness of ASD repair. Localization during these catheter based procedures traditionally has relied on bi-plane fluoroscopy; more recently trans-esophageal echocardiography (TEE) and intra-cardiac echocardiography (ICE) have been used to navigate these procedures. Although there is a high success rate using the transcatheter occlusion …

Synthesis And Characterization Of Novel Platinum(Ii) And Platinum(Iv) Complexes Containing 4,4′--Disubstituted--2,2′--Bipyridine Ligands For The Treatment Of Cancer, Van Vo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Three series of platinum(II) and platinum(IV) complexes containing 4,4′-disubstituted-2,2′-bipyridine ligands have been synthesized and characterized by 1H NMR, 13C NMR spectroscopy, elemental analysis, mass spectroscopy, and differential scanning calorimetry measurements. The MTS cell proliferation assay was used to examine the in vitro anti-proliferative activities of these complexes in various human breast, lung, and prostate cancer cells. The cell's response to the complexes varies between different cell lines; however, the low EC₅₀ values determined from the MTS data indicate that several of the complexes are much more potent than cisplatin.

Flow cytometric analysis of selected compounds revealed induction of apoptosis …

Sleep Environment Risks For Younger And Older Infants., Jeffrey D. Colvin, Vicki Collie-Akers, Christy Schunn, Rachel Y. Moon

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: Sudden infant death syndrome and other sleep-related causes of infant mortality have several known risk factors. Less is known about the association of those risk factors at different times during infancy. Our objective was to determine any associations between risk factors for sleep-related deaths at different ages.

METHODS: A cross-sectional study of sleep-related infant deaths from 24 states during 2004-2012 contained in the National Center for the Review and Prevention of Child Deaths Case Reporting System, a database of death reports from state child death review teams. The main exposure was age, divided into younger (0-3 months) and older …

Strategies To Sensitize Bladder Cancer Cells To Small Molecule Inhibitors Targeting The Pi3k Pathway, Giovanni Nitti

Dissertations and Theses (Open Access)

After many years of cancer research, it is well accepted by the scientific community that the future cure for this disease lies in a personalized therapeutic approach. Anticipating therapeutic outcome based on the genetic signature of a tumor has become the new paradigm. The PI3K pathway represents an ideal target for bladder cancer, as many of the key proteins of this pathway are altered or mutated in this particular type of cancer. Several small molecule inhibitors have been developed to target this pathway, but their efficacy has been shown to be heterogeneous among different cell lines and mostly cytostatic but …

Regulation Of L1 Expression And Retrotransposition By Melatonin And Its Receptor: Implications For Cancer Risk Associated With Light Exposure At Night., Dawn Deharo, Kristine J Kines, Mark Sokolowski, Robert T Dauchy, Vincent A Streva, Steven M Hill, John P Hanifin, George Brainard, David E Blask, Victoria P Belancio

Department of Neurology Faculty Papers

Expression of long interspersed element-1 (L1) is upregulated in many human malignancies. L1 can introduce genomic instability via insertional mutagenesis and DNA double-strand breaks, both of which may promote cancer. Light exposure at night, a recently recognized carcinogen, is associated with an increased risk of cancer in shift workers. We report that melatonin receptor 1 inhibits mobilization of L1 in cultured cells through downregulation of L1 mRNA and ORF1 protein. The addition of melatonin receptor antagonists abolishes the MT1 effect on retrotransposition in a dose-dependent manner. Furthermore, melatonin-rich, but not melatonin-poor, human blood collected at different times during the circadian …

Simultaneous Analysis Of T Helper Subsets (Th1, Th2, Th9, Th17, Th22, Tfh, Tr1 And Tregs) Markers Expression In Periapical Lesions Reveals Multiple Cytokine Clusters Accountable For Lesions Activity And Inactivity Status, Ana Claudia Araujo-Pires, Carolina Favaro Francisconi, Cláudia Cristina Biguetti, Franco Cavalla, Andreza Maria Fabio Aranha, Ariadne Letra, Ana Paula Favaro Trombone, Marcelo Faveri, Renato Menezes Silva, Gustavo P. Garlet

School of Podiatric Medicine Publications

Previous studies demonstrate that the balance between pro- and anti-inflammatory mediators determines the stable or progressive nature of periapical granulomas by modulating the balance of the osteoclastogenic factor RANKL and its antagonist OPG. However, the cytokine networks operating in the development of periapical lesions are quite more complex than what the simple pro- versus anti-inflammatory mediators' paradigm suggests. Here we simultaneously investigated the patterns of Th1, Th2, Th9, Th17, Th22, Thf, Tr1 and Tregs cytokines/markers expression in human periapical granulomas.

Methods:

The expression of TNF-α, IFN-γ, IL-17A, IL23, IL21, IL-33, IL-10, IL-4, IL-9, IL-22, FOXp3 markers (via RealTimePCR array) was …

Empiric Deworming And Cd4 Count Recovery In Hiv-Infected Ugandans Initiating Antiretroviral Therapy, Alexander J. Lankowski, Alexander C. Tsai, Michael Kanyesigye, Mwebesa B. Bwana, Jessica E. Haberer, Megan Wenger, Jeffrey N. Martin, David Bangsberg, Peter W. Hunt, Mark J. Siedner

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: There is conflicting evidence on the immunologic benefit of treating helminth co-infections (‘‘deworming’’) in HIV-infected individuals. Several studies have documented reduced viral load and increased CD4 count in antiretroviral therapy (ART) naive individuals after deworming. However, there are a lack of data on the effect of deworming therapy on CD4 count recovery among HIV-infected persons taking ART.

Methodology/Principal Findings: To estimate the association between empiric deworming therapy and CD4 count after ART initiation, we performed a retrospective observational study among HIV-infected adults on ART at a publicly operated HIV clinic in southwestern Uganda. Subjects were assigned as having received …

Rorα Binds To E2f1 To Inhibit Cell Proliferation And Regulate Mammary Gland Branching Morphogenesis, Gaofeng Xiong, Ren Xu

Markey Cancer Center Faculty Publications

Retinoic acid receptor-related orphan nuclear receptor alpha (RORα) is a potent tumor suppressor that reduces cell proliferation and inhibits tumor growth. However, the molecular mechanism by which it inhibits cell proliferation remains unknown. We demonstrate a noncanonical nuclear receptor pathway in which RORα binds to E2F1 to inhibit cell cycle progression. We showed that RORα bound to the heptad repeat and marked box region of E2F1 and suppressed E2F1-regulated transcription in epithelial cells. Binding of RORα inhibited E2F1 acetylation and its DNA-binding activity by recruiting histone deacetylase 1 (HDAC1) to the protein complexes. Knockdown of HDAC1 or inhibition of HDAC …

The Mucosal Expression Pattern Of Interferon-Ε In Rhesus Macaques, Andrew Demers, Guobin Kang, Fangrui Ma, Wuxun Lu, Zhe Yuan, Yue Li, Mark Lewis, Edmundo N. Kraiselburd, Luis Montaner, Qingsheng Li

Qingsheng Li Publications

Type I IFNs play an important role in innate and adaptive immunity against viral infections. A novel type I IFN, namely IFN-ε, which can protect against vaginal transmission of HSV2 and Chlamydia muridarum bacterial infection, has been described in mice and humans. Nevertheless, the principle cell type and the expression pattern of IFN-ε in tissues remain uncertain. In addition, the expression of IFN-ε in Indian rhesus macaques (Macaca mulatta) has not been reported. Here, we analyzed IFN-ε expression in multiple mucosal sites of uninfected or SIV-infected Indian rhesus macaques using IHCS. We report for the first time the …

The Kras/Mapk Pathway And Ligand Independent Activation Of Erα: Implications For The Treatment Of Endometrial Cancer, Kari Ring

Dissertations and Theses (Open Access)

Hormonal therapy remains a first line option for the treatment of recurrent endometrial cancer (EC), however, many tumors demonstrate de novo or acquired resistance. Member kinases of the PI3K/AKT and Ras/MAPK pathways activate estrogen receptor α (ERα) independent of estrogen, however, few studies have evaluated the role of the Ras/MAPK pathway in predicting response to hormonal therapy in EC. The aims of this project were to evaluate the role of ligand independent activation of ERα in EC and to explore therapeutic implications for the treatment of recurrent EC.

A xenograft model for recurrent EC was used to evaluate the effect …
