The Adjuvanticity Of An O. Volvulus-Derived Rov-Asp-1 Protein In Mice Using Sequential Vaccinations And In Non-Human Primates, Jing Wang, Nancy Trichoche, Lanying Du, Meredith Hunter, Bin Zhan, Gaddam Goud, Elizabeth S. Didier, Jing Liu, Lu Lu, Preston A. Marx, Shibo Jiang, Sara Lustigman

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Adjuvants potentiate antigen-specific protective immune responses and can be key elements promoting vaccine effectiveness. We previously reported that the Onchocerca volvulusrecombinant protein rOv-ASP-1 can induce activation and maturation of naïve human DCs and therefore could be used as an innate adjuvant to promote balanced Th1 and Th2 responses to bystander vaccine antigens in mice. With a few vaccine antigens, it also promoted a Th1-biased response based on pronounced induction of Th1-associated IgG2a and IgG2b antibody responses and the upregulated production of Th1 cytokines, including IL-2, IFN-γ, TNF-α and IL-6. However, because it is a protein, the r …

Cell-Free Circulating Mirna Biomarkers In Cancer., Meng-Hsuan Mo, Liang Chen, Yebo Fu, Wendy Wang, Sidney W. Fu

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Considerable attention and an enormous amount of resources have been dedicated to cancer biomarker discovery and validation. However, there are still a limited number of useful biomarkers available for clinical use. An ideal biomarker should be easily assayed with minimally invasive medical procedures but possess high sensitivity and specificity. Commonly used circulating biomarkers are proteins in serum, most of which require labor-intensive analysis hindered by low sensitivity in early tumor detection. Since the deregulation of microRNA (miRNA) is associated with cancer development and progression, profiling of circulating miRNAs has been used in a number of studies to identify novel minimally …

Do Photoperiodic Changes In Melatonin Secretion Detrimentally Affect The Female Reproductive Cycle?, Riki Szlafrok

The Science Journal of the Lander College of Arts and Sciences

Melatonin, better known as "the hormone of darkness," is secreted by the pineal gland during the night and helps us fall asleep. Because its internal regulation depends on light, melatonin is part of chronobiology, the study of biological mechanisms and their adaptations to lunar and solar related rhythms (Klein et al. 1991). Therefore, photoperiod changes greatly impact melatonin concentration, influencing changes in neuronal and hormonal mechanisms of the photo neuro-endocrine systems, namely reproduction. Research has shown that a disruption in the circadian rhythm of melatonin due to photoperiod changes detrimentally affects the rhythmic function of the female reproductive cycle. Research …

Nuclear Receptor Expression And Characterization Of The Major Retinoic Acid Target Gene In Melanoma, Linda L. Eastham

Theses, Dissertations and Capstones

Malignant melanoma is the primary cause of death from all diseases arising from the skin and it is one of the most resistant tumors to standard treatment options. The increasing incidence of melanoma and its poor prognosis makes the understanding of melanoma cell biology very important. Melanoma progression is a complex, multi-step process, and the molecular events leading to melanoma tumor cell proliferation and invasion still need further examination. This study is focused on measuring the expression and activity of two specific genes and their protein counterparts that are altered during melanoma progression. It also examines the mechanism through which …

Discovery Of Prostamide F2Α And Its Role In Inflammatory Pain And Dorsal Horn Nociceptive Neuron Hyperexcitability, Luisa Gatta, Fabiana Piscitelli, Catia Giordano, Serana Boccella, Aron H. Lichtman, Sebatino Maione, Vincenzo Di Marzo

Pharmacology and Toxicology Publications

It was suggested that endocannabinoids are metabolized by cyclooxygenase (COX)-2 in the spinal cord of rats with kaolin/λ-carrageenan-induced knee inflammation, and that this mechanism contributes to the analgesic effects of COX-2 inhibitors in this experimental model. We report the development of a specific method for the identification of endocannabinoid COX-2 metabolites, its application to measure the levels of these compounds in tissues, and the finding of prostamide F2α (PMF2α) in mice with knee inflammation. Whereas the levels of spinal endocannabinoids were not significantly altered by kaolin/λ-carrageenan-induced knee inflammation, those of the COX-2 metabolite of AEA, PMF2α, were strongly elevated. The …

The Role Of Vascular Endothelial Growth Factor At The Blood-Brain Barrier In Diabetes, Aileen J. Marcelo

Theses, Dissertations and Capstones

Diabetes is a risk factor for stroke and vascular dementia. Clinical studies using gadolinium-magnetic resonance imaging techniques have shown diabetic patients exhibit a permeability increase at the blood-brain barrier (BBB) (Starr et al, 2003). The BBB, a vascular interface at the level of brain microvascular vessels, functions to provide nutrients and oxygen from the peripheral circulation, mediates waste efflux from the brain, and protects the brain from toxins. These functions are due to the presence of tight junction proteins. Animal studies have shown increased BBB permeability is due to a decrease in these proteins (Hawkins et al, 2007). Based on …

Effects Of Combined Opioids On Pain And Mood In Mammals, David J. Mokler, Richard H. Rech, Shannon L. Briggs

Biomedical Sciences Faculty Publications

The authors review the opioid literature for evidence of increased analgesia and reduced adverse side effects by combining opioid-receptor (MOR) agonists, kappa-opioid-recepter (KOR) agonists, and nonselective low-dose-opioid antagonists (LD-ANT). We tested fentanyl (MOR agonist) and spiradoline (KOR agonist), singly and combined, against somatic and visceral pain models. Combined agonists induced additive analgesia in somatic pain and synergistic analgesia in visceral pain. Other investigators report similar effects and reduced tolerance and dependence with combined MOR agonist and KOR agonist. LD-Ant added to either a MOR agonist or KOR agonist markedly enhanced analgesia of either agonist. In accordance with other place-condition (PC) …

Myd88-Dependent Signaling Influences Fibrosis And Alternative Macrophage Activation During Staphylococcus Aureus Biofilm Infection., Mark L. Hanke, Amanda Angle, Tammy Kielian

Journal Articles: Pathology and Microbiology

Bacterial biofilms represent a significant therapeutic challenge based on their ability to evade host immune and antibiotic-mediated clearance. Recent studies have implicated IL-1β in biofilm containment, whereas Toll-like receptors (TLRs) had no effect. This is intriguing, since both the IL-1 receptor (IL-1R) and most TLRs impinge on MyD88-dependent signaling pathways, yet the role of this key adaptor in modulating the host response to biofilm growth is unknown. Therefore, we examined the course of S. aureus catheter-associated biofilm infection in MyD88 knockout (KO) mice. MyD88 KO animals displayed significantly increased bacterial burdens on catheters and surrounding tissues during early infection, which …

Apo A1 Mimetic Rescues The Diabetic Phenotype Of Ho-2 Knockout Mice Via An Increase In Ho-1 Adiponectin And Lkbi Signaling Pathway, Jian Cao, Nitin Puri, Komal Sodhi, Lars Bellner, Nader G. Abraham, Attallah Kappas

Biochemistry and Microbiology

Insulin resistance, with adipose tissue dysfunction, is one of the hallmarks of metabolic syndrome. We have reported a metabolic syndrome-like phenotype in heme oxygenase (HO)-2 knockout mice, which presented with concurrent HO-1 deficiency and were amenable to rescue by an EET analog. Apo A-I mimetic peptides, such as L-4F, have been shown to induce HO-1 expression and decrease oxidative stress and adiposity. In this study we aimed to characterize alleviatory effects of HO-1 induction (if any) on metabolic imbalance observed in HO-2 KO mice. In this regard, HO-2^(−/−) mice were injected with 2 mg/kg/day L-4F, or vehicle, i.p., for …

Consumption Of High Ω-3 Fatty Acid Diet Suppressed Prostate Tumorigenesis In C3(1) Tag Mice, Juliana A. Akinsete, Gabriela Ion, Theodore R. Witte, W. Elaine Hardman

Biochemistry and Microbiology

Prostate cancer incidence and mortality are high in the Western world and high ω-6/ω-3 PUFA in the Western diet may be a contributing factor. We investigated whether changing from a diet that approximates ω-6 fat content of the Western diet to a high ω-3 fat diet at adulthood might reduce prostate cancer risk. Female SV 129 mice that had consumed a high ω-6 diet containing corn oil for 2 weeks were bred with homozygous C3(1)Tag transgenic male mice. All male offspring were weaned to the corn oil diet (CO) until postpuberty when half of the male offspring were transferred to …

Tracing Notochord-Derived Cells Using A Noto-Cre Mouse: Implications For Intervertebral Disc Development., Matthew R Mccann, Owen J Tamplin, Janet Rossant, Cheryle A Séguin

Physiology and Pharmacology Publications

Back pain related to intervertebral disc degeneration is the most common musculoskeletal problem, with a lifetime prevalence of 82%. The lack of effective treatment for this widespread problem is directly related to our limited understanding of disc development, maintenance and degeneration. The aim of this study was to determine the developmental origins of nucleus pulposus cells within the intervertebral disc using a novel notochord-specific Cre mouse. To trace the fate of notochordal cells within the intervertebral disc, we derived a notochord-specific Cre mouse line by targeting the homeobox gene Noto. Expression of this gene is restricted to the node and …

Acid Sphingomyelinase Gene Knockout Ameliorates Hyperhomocysteinemic Glomerular Injury In Mice Lacking Cystathionine-Β-Synthase, Krishna M. Boini, Min Xia, Justine M. Abais, Ming Xu, Cai-Xia Li, Pin-Lan Li

Pharmacology and Toxicology Publications

Acid sphingomyelinase (ASM) has been implicated in the development of hyperhomocysteinemia (hHcys)-induced glomerular oxidative stress and injury. However, it remains unknown whether genetically engineering of ASM gene produces beneficial or detrimental action on hHcys-induced glomerular injury. The present study generated and characterized the mice lacking cystathionine β-synthase (Cbs) and Asm mouse gene by cross breeding Cbs+/− and Asm+/− mice. Given that the homozygotes of Cbs−/−/Asm−/− mice could not survive for 3 weeks. Cbs+/−/Asm+/+, Cbs+/−/Asm+/− and Cbs+/−/Asm−/− as well as their Cbs wild type littermates were used to study the role of Asm−/− under a background of Cbs+/− with hHcys. HPLC …

Vascular Inflammatory Cells In Hypertension., David G Harrison, Paul J. Marvar, Jens M Titze

Pharmacology and Physiology Faculty Publications

Hypertension is a common disorder with uncertain etiology. In the last several years, it has become evident that components of both the innate and adaptive immune system play an essential role in hypertension. Macrophages and T cells accumulate in the perivascular fat, the heart and the kidney of hypertensive patients, and in animals with experimental hypertension. Various immunosuppressive agents lower blood pressure and prevent end-organ damage. Mice lacking lymphocytes are protected against hypertension, and adoptive transfer of T cells, but not B cells in the animals restores their blood pressure response to stimuli such as angiotensin II or high salt. …

Methods: The crude extract of A. spinosus was studied in-vivo for bronchodilator and laxative activities and in-vitro using isolated tissue preparations which were mounted in tissue baths assembly containing physiological salt solutions, maintained at 37°C and aerated with carbogen, to assess the spasmolytic effect and to find out the possible underlying mechanisms.
Results: In the in-vivo experiments in mice, the administration of A. spinosus increased fecal output at doses of 100 …

Interferon-Α Regulates Glutaminase 1 Promoter Through Stat1 Phosphorylation: Relevance To Hiv-1 Associated Neurocognitive Disorders., Lixia Zhao, Yunlong Huang, Changhai Tian, Lynn Taylor, Norman Curthoys, Yi Wang, Hamilton Vernon, Jialin C. Zheng

Journal Articles: Pharmacology & Experimental Neuroscience

HIV-1 associated neurocognitive disorders (HAND) develop during progressive HIV-1 infection and affect up to 50% of infected individuals. Activated microglia and macrophages are critical cell populations that are involved in the pathogenesis of HAND, which is specifically related to the production and release of various soluble neurotoxic factors including glutamate. In the central nervous system (CNS), glutamate is typically derived from glutamine by mitochondrial enzyme glutaminase. Our previous study has shown that glutaminase is upregulated in HIV-1 infected monocyte-derived-macrophages (MDM) and microglia. However, how HIV-1 leads to glutaminase upregulation, or how glutaminase expression is regulated in general, remains unclear. In …

Identification Of The Functional Binding Pocket For Compounds Targeting Small-Conductance Ca²⁺-Activated Potassium Channels., Miao Zhang, John M Pascal, Marcel Schumann, Roger S Armen, Ji-Fang Zhang

Department of Molecular Physiology and Biophysics Faculty Papers

Small- and intermediate-conductance Ca(2+)-activated potassium channels, activated by Ca(2+)-bound calmodulin, have an important role in regulating membrane excitability. These channels are also linked to clinical abnormalities. A tremendous amount of effort has been devoted to developing small molecule compounds targeting these channels. However, these compounds often suffer from low potency and lack of selectivity, hindering their potential for clinical use. A key contributing factor is the lack of knowledge of the binding site(s) for these compounds. Here we demonstrate by X-ray crystallography that the binding pocket for the compounds of the 1-ethyl-2-benzimidazolinone (1-EBIO) class is located at the calmodulin-channel interface. …

Aleuria Aurantia Lectin (Aal)-Reactive Immunoglobulin G Rapidly Appears In Sera Of Animals Following Antigen Exposure., Songming Chen, Chen Lu, Hongbo Gu, Anand Mehta, Jianwei Li, Patrick B Romano, David Horn, D Craig Hooper, Carthene R Bazemore-Walker, Timothy Block

Department of Cancer Biology Faculty Papers

We have discovered an Aleuria Aurantia Lectin (AAL)-reactive immunoglobulin G (IgG) that naturally occurs in the circulation of rabbits and mice, following immune responses induced by various foreign antigens. AAL can specifically bind to fucose moieties on glycoproteins. However, most serum IgGs are poorly bound by AAL unless they are denatured or treated with glycosidase. In this study, using an immunogen-independent AAL-antibody microarray assay that we developed, we detected AAL-reactive IgG in the sera of all animals that had been immunized 1-2 weeks previously with various immunogens with and without adjuvants and developed immunogen-specific responses. All of these animals subsequently …

Epigenetic Variation May Compensate For Decreased Genetic Variation With Introductions: A Case Study Using House Sparrows (Passer Domesticus) On Two Continents, Aaron W. Schrey, Courtney A. C. Coon, Michael T. Grispo, Mohammed Awad, Titus Imboma, Earl D. Mccoy, Henry R. Mushinsky, Christina L. Richards, Lynn B. Martin

Integrative Biology Faculty and Staff Publications

Epigenetic mechanisms impact several phenotypic traits and may be important for ecology and evolution. The introduced house sparrow (Passer domesticus) exhibits extensive phenotypic variation among and within populations. We screened methylation in populations from Kenya and Florida to determine if methylation varied among populations, varied with introduction history (Kenyan invasion < 50 years old, Florida invasion ~150 years old), and could potentially compensate for decrease genetic variation with introductions. While recent literature has speculated on the importance of epigenetic effects for biological invasions, this is the first such study among wild vertebrates. Methylation was more frequent in Nairobi, and outlier loci suggest that populations may be differentiated. Methylation diversity was similar between populations, in spite of known lower genetic diversity in Nairobi, which suggests that epigenetic variation may compensate for decreased genetic diversity as a source of phenotypic variation during introduction. Our results suggest that methylation differences may be common among house sparrows, but research is needed to discern whether methylation impacts phenotypic variation.

Ethnopharmacological Studies On Chrozophora Prostrata In Perspective Of Its Folkloric Reputation As Purgative, Usman Arshad, Khalid Hussain Janbaz, Samra Bashir, Najeeb-Ur- Rehman, Hassan Mehmood, Anwar-Ul-Hassan Gilani

Department of Biological & Biomedical Sciences

This study was undertaken to validate the medicinal use of Chrozophora prostrata in constipation. The crude extract of C prostrata produced laxative effect in mice at 100 and 300 mg/kg, similar to carbachol and castor oil. In spontaneously contracting rabbit jejunum tissues, C. prostrata (0.01-3 mg/mL) exhibited atropine-sensitive spasmogenic effect, which was reproducible in guinea-pig ileum. Interestingly, at high concentrations, C. prostrata showed concentration-dependent inhibitory effect on rabbit jejunum, suggesting the presence of accompanied spasmolytic activity. When tested on induced contractions, C. prostrata completely relaxed low K+-induced contraction, while partially inhibited high K+, similar to cromakalim. Tetraethylammonium pretreatment abolished the …

Statin-Mediated Attenuation Of Chemokine Expression In Peripheral Nerve Vascular Endothelial Cells, Kelly Ann Langert

Dissertations

Pro-inflammatory cytokines, including tumor necrosis factor-α (TNF-α), play a pivotal role in the pathogenesis of Guillain-Barré Syndrome (GBS), a debilitating autoimmune disorder that affects the peripheral nervous system. By up-regulating endothelial expression of chemokines and cell adhesion molecules (CAMs), TNF-α facilitates the recruitment and trafficking of autoreactive leukocytes across the blood-nerve barrier and into peripheral nerves, an early pathological hallmark of GBS. Literature indicates that TNF-α, monocyte chemoattractant protein-1 (MCP-1), and intercellular adhesion molecule-1 (ICAM-1) are locally increased in patients with GBS, correlating with disease severity. Similar findings have been demonstrated in an animal model of GBS, experimental autoimmune neuritis …

The Effects Of Smooth Muscle Cells On Engineered Microvasculatures In Fibrin Hydrogels, Areck A. Ucuzian

Dissertations

Capillaries are comprised of two cell types: the endothelial cells (ECs) which line the lumen of the capillary, and the supporting pericytes which are closely apposed to the abluminal surface of the capillary wall (sometimes called mural cells). These pericytes are phenotypic derivations of mesenchymal organ stromal cells (from smooth muscle cells and fibroblasts in blood vessels, for example), are recruited and incorporate into the neocapillaries, and are known to mediate reciprocal interactions with ECs during angiogenesis. The overall purpose of this project is to determine how smooth muscle cells (SMCs) affect angiogenesis during microvascular development in fibrin hydrogels using …

Forebrain Noradrenergic Alterations And Anxiety After Myocardial Infarction, Jaimee Glasgow

Dissertations

Thirty to 45% of patients who suffer a myocardial infarction (MI) develop anxiety disorders and/or depression, and the development of mood and anxiety disorders following MI is a major risk factor for cardiovascular morbidity and mortality. Depressed post-MI patients have an increased risk of fatal arrhythmias, which are often precipitated by emotional stressors. However, the central nervous system mechanisms that contribute to post-MI anxiety and arrhythmia susceptibility are unknown. Therefore, the studies reported in this dissertation were designed to test the hypothesis that alterations in noradrenergic transmission in the forebrain contribute to the development of anxiety disorders and arrhythmia susceptibility …

Vorinostat: A Potent Agent To Prevent And Treat Laser-Induced Corneal Haze, Ashish Tandon, Jonathan C. K. Tovey, Michael R. Waggoner, Ajay Sharma, John W. Cowden, Daniel J. Gibson, Yuanjing Liu, Gregory S. Schultz, Rajiv R. Mohan

PURPOSE—This study investigated the efficacy and safety of vorinostat, a deacetylase (HDAC) inhibitor, in the treatment of laser-induced corneal haze following photorefractive keratectomy (PRK) in rabbits in vivo and transforming growth factor beta 1 (TGFβ1) -induced corneal fibrosis in vitro.

METHODS—Corneal haze in rabbits was produced with −9.00 diopters (D) PRK. Fibrosis in cultured human and rabbit corneal fibroblasts was activated with TGFβ1. Vorinostat (25 μm) was topically applied once for 5 minutes on rabbit cornea immediately after PRK for in vivo studies. Vorinostat (0 to 25 μm) was given to human/rabbit corneal fibroblasts for 5 minutes or 48 …

Prmt5 And The Role Of Symmetrical Dimethylarginine In Chromatoid Bodies Of Planarian Stem Cells, Labib Rouhana, Ana P. Vieira, Rachel H. Roberts-Galbraith, Phillip A. Newmark

Biological Sciences Faculty Publications

Planarian flatworms contain a population of adult stem cells (neoblasts) that proliferate and generate cells of all tissues during growth, regeneration and tissue homeostasis. A characteristic feature of neoblasts is the presence of chromatoid bodies, large cytoplasmic ribonucleoprotein (RNP) granules morphologically similar to structures present in the germline of many organisms. This study aims to reveal the function, and identify additional components, of planarian chromatoid bodies. We uncover the presence of symmetrical dimethylarginine (sDMA) on chromatoid body components and identify the ortholog of protein arginine methyltransferase PRMT5 as the enzyme responsible for sDMA modification in these proteins. RNA interference-mediated depletion …

Effects Of Adipocyte Deficiency Of Angiotensin Type 1a Receptors In Models Of Obesity And Hypercholesterolemia, Kelly Anne Putnam

Theses and Dissertations--Nutritional Sciences

Adipocytes express angiotensin II (AngII) receptors; however the direct effects of AngII at the adipocyte remain unclear. Knockout mouse models of renin-angiotensin system components exhibit reduced body weight, reduced adiposity, improved glucose tolerance, and improved blood pressure when fed high fat diets, which may be due to reduced action of AngII through the AT1aR in adipocytes. Additionally, hypercholesterolemic AT1aR deficient mice are protected from AngII-induced increases in atherosclerosis and abdominal aortic aneurysm (AAA) formation. We hypothesized that deficiency of AT1aR in adipocytes would reduce the development of obesity, obesity-induced disorders, and vascular diseases. To test this hypothesis, we created a …
