Functional Proteomic Analysis Reveals The Involvement Of Kiaa1199 In Breast Cancer Growth, Motility And Invasiveness., Mohammad-Saeid Jami, Jinxuan Hou, Miao Liu, M L. Varney, Hesham Hassan, Jixin Dong, Liying Geng, J. Wang, Fang Yu, Xin Huang, Hong Peng, Kai Fu, Yan Li, Rakesh Singh, Shi-Jian Ding

Journal Articles: Pathology and Microbiology

BACKGROUND: KIAA1199 is a recently identified novel gene that is up-regulated in human cancer with poor survival. Our proteomic study on signaling polarity in chemotactic cells revealed KIAA1199 as a novel protein target that may be involved in cellular chemotaxis and motility. In the present study, we examined the functional significance of KIAA1199 expression in breast cancer growth, motility and invasiveness.

METHODS: We validated the previous microarray observation by tissue microarray immunohistochemistry using a TMA slide containing 12 breast tumor tissue cores and 12 corresponding normal tissues. We performed the shRNA-mediated knockdown of KIAA1199 in MDA-MB-231 and HS578T cells to …

The Wnt/Planar Cell Polarity Pathway Component Vangl2 Induces Synapse Formation Through Direct Control Of N-Cadherin, Tadahiro Nagaoka, Riuko Ohashi, Ayumu Inutsuka, Seiko Sakai, Nobuyoshi Fujisawa, Minesuke Yokoyama, Yina H. Huang, Michihiro Igarashi, Masashi Kishi

Dartmouth Scholarship

Although regulators of the Wnt/planar cell polarity (PCP) pathway are widely expressed in vertebrate nervous systems, their roles at synapses are unknown. Here, we show that Vangl2 is a postsynaptic factor crucial for synaptogenesis and that it coprecipitates with N-cadherin and PSD-95 from synapse-rich brain extracts. Vangl2 directly binds N-cadherin and enhances its internalization in a Rab5-dependent manner. This physical and functional interaction is suppressed by β-catenin, which binds the same intracellular region of N-cadherin as Vangl2. In hippocampal neurons expressing reduced Vangl2 levels, dendritic spine formation as well as synaptic marker clustering is significantly impaired. Furthermore, Prickle2, another postsynaptic …

The Merg1a Channel Modulates Skeletal Muscle Murf1, But Not Mafbx, Expression., Amber L Pond, Carrie Nedele, Wen-Horng Wang, Xun Wang, Claire Walther, Christine Jaeger, Kevin S Bradley, Huahua Du, Naoya Fujita, Gregory H Hockerman, Kevin M Hannon

Publications

INTRODUCTION: We investigated the mechanism by which the MERG1a K+ channel increases ubiquitin proteasome proteolysis (UPP).

METHODS: Hindlimb suspension and electro-transfer of Merg1a cDNA into mouse gastrocnemius muscles induced atrophy.

RESULTS: Atrophic gastrocnemius muscles of hindlimb-suspended mice express Merg1a, Murf1, and Mafbx genes. Electrotransfer of Merg1a significantly decreases muscle fiber size (12.6%) and increases UPP E3 ligase Murf1 mRNA (2.1-fold) and protein (23.7%), but does not affect Mafbx E3 ligase expression. Neither Merg1a-induced decreased fiber size nor Merg1a-induced increased Murf1 expression is curtailed significantly by coexpression of inactive HR-Foxo3a, a gene encoding a transcription factor known to induce Mafbx expression. …

Tachycardia Mediated Cardiomyopathy: Pathophysiology, Mechanisms, Clinical Features And Management., Shuchita Gupta, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

Tachycardia mediated cardiomyopathy (TMC) is a reversible form of dilated cardiomyopathy that can occur with most supraventricular and ventricular arrhythmias. Despite the plethora of literature describing this entity in animal models, as well as humans, it remains poorly understood. Over the last decade, new etiologies of TMC, such as frequent premature ventricular complexes in normal hearts, have been identified. Recent advances in catheter-based ablation therapies, particularly for atrial fibrillation and ventricular arrhythmias, have added a new dimension to the treatment of this condition. This review describes the pathophysiology, proposed mechanisms, clinical features and management in various arrhythmic conditions.

Ocean Acidification Impairs Vermetid Reef Recruitment., Marco Milazzo, Riccardo Rodolfo-Metalpa, Vera Bin San Chan, Maoz Fine, Cinzia Alessi, Vengatesen Thiyagarajan, Jason M. Hall-Spencer, Renato Chemello

School of Biological and Marine Sciences

Vermetids form reefs in sub-tropical and warm-temperate waters that protect coasts from erosion, regulate sediment transport and accumulation, serve as carbon sinks and provide habitat for other species. The gastropods that form these reefs brood encapsulated larvae; they are threatened by rapid environmental changes since their ability to disperse is very limited. We used transplant experiments along a natural CO2 gradient to assess ocean acidification effects on the reef-building gastropod Dendropoma petraeum. We found that although D. petraeum were able to reproduce and brood at elevated levels of CO2, recruitment success was adversely affected. Long-term exposure to acidified conditions predicted …

Quantitative Field Testing Heterodera Glycines From Metagenomic Dna Samples Isolated Directly From Soil Under Agronomic Production., Yan Li, Gary W. Lawrence, Shien Lu, Clarissa Balbalian, Vincent P. Klink

CALS Publications

A quantitative PCR procedure targeting the Heterodera glycines ortholog of the Caenorhabditis elegans uncoordinated-78 gene was developed. The procedure estimated the quantity of H. glycines from metagenomic DNA samples isolated directly from field soil under agronomic production. The estimation of H. glycines quantity was determined in soil samples having other soil dwelling plant parasitic nematodes including Hoplolaimus, predatory nematodes including Mononchus, free-living nematodes and biomass. The methodology provides a framework for molecular diagnostics of nematodes from metagenomic DNA isolated directly from field soil.

Attention Deficit Associated With Early Life Interictal Spikes In A Rat Model Is Improved With Acth, Amanda E. Hernan, Abigail Alexander, Pierre-Pascal Lenck-Santini, Rod C. Scott

Dartmouth Scholarship

Children with epilepsy often present with pervasive cognitive and behavioral comorbidities including working memory impairments, attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder. These non-seizure characteristics are severely detrimental to overall quality of life. Some of these children, particularly those with epilepsies classified as Landau-Kleffner Syndrome or continuous spike and wave during sleep, have infrequent seizure activity but frequent focal epileptiform activity. This frequent epileptiform activity is thought to be detrimental to cognitive development; however, it is also possible that these IIS events initiate pathophysiological pathways in the developing brain that may be independently associated with cognitive deficits. These …

Irf8 Suppresses Pathological Cardiac Remodelling By Inhibiting Calcineurin Signalling., Ding-Sheng Jiang, Xiang Wei, Xiao-Fei Zhang, Yu Liu, Yan Zhang, Ke Chen, Lu Gao, Heng Zhou, Xue-Hai Zhu, Peter P. Liu, Wayne Bond Lau, Xin-Liang Ma, Yunzeng Zou, Xiao-Dong Zhang, Guo-Chang Fan, Hongliang Li

Department of Emergency Medicine Faculty Papers

Interferon regulatory factor 8 (IRF8) is known to affect the innate immune response, for example, by regulating the differentiation and function of immune cells. However, whether IRF8 can influence cardiac hypertrophy is unknown. Here we show that IRF8 levels are decreased in human dilated/hypertrophic cardiomyopathic hearts and in murine hypertrophic hearts. Mice overexpressing Irf8 specifically in the heart are resistant to aortic banding (AB)-induced cardiac hypertrophy, whereas mice lacking IRF8 either globally or specifically in cardiomyocytes develop an aggravated phenotype induced by pressure overload. Mechanistically, we show that IRF8 directly interacts with NFATc1 to prevent NFATc1 translocation and thus inhibits …

Prevention Of Arteriovenous Shunt Occlusion Using Microbubble And Ultrasound Mediated Thromboprophylaxis., Shelby Kutty, Juefei Wu, James M. Hammel, Joseph R. Abraham, Jeeva Venkataraman, Ibrahim Abdullah, David A. Danford, Stanley J. Radio, John Lof, Thomas R. Porter

Journal Articles: Pediatrics

BACKGROUND: Palliative shunts in congenital heart disease patients are vulnerable to thrombotic occlusion. High mechanical index (MI) impulses from a modified diagnostic ultrasound (US) transducer during a systemic microbubble (MB) infusion have been used to dissolve intravascular thrombi without anticoagulation, and we sought to determine whether this technique could be used prophylactically to reduce thrombus burden and prevent occlusion of surgically placed extracardiac shunts.

METHODS AND RESULTS: Heparin-bonded ePTFE tubular vascular shunts of 4 mm×2.5 cm (Propaten; W.L Gore) were surgically placed in 18 pigs: a right-sided side-to-side arteriovenous (AV, carotid-jugular) shunt, and a left-sided arterio-arterial (AA, carotid-carotid) interposition shunt …

Induction Of Autophagy Restores The Loss Of Sevoflurane Cardiac Preconditioning Seen With Prolonged Ischemic Insult., Mayumi Shiomi, Masami Miyamae, Genzou Takemura, Kazuhiro Kaneda, Yoshitaka Inamura, Anna Onishi, Shizuka Koshinuma, Yoshihiro Momota, Toshiaki Minami, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

Sevoflurane preconditioning against myocardial ischemia-reperfusion injury is lost if the ischemic insult is too long. Emerging evidence suggests that induction of autophagy may also confer cardioprotection against ischemia-reperfusion injury. We examined whether induction of autophagy prolongs sevoflurane preconditioning protection during a longer ischemic insult. Isolated guinea pigs hearts were subjected to 30 or 45 min ischemia, followed by 120 min reperfusion (control). Anesthetic preconditioning was elicited with 2% sevoflurane for 10 min prior to ischemia (SEVO-30, SEVO-45). Chloramphenicol (autophagy upregulator, 300 µM) was administered starting 20 min before ischemia and throughout reperfusion in SEVO-45 (SEVO-45+CAP). To inhibit autophagy, 3-methyladenine (10 …

Medial Septal Cholinergic Neurons Modulate Isoflurane Anesthesia., Siew Kian Tai, Jingyi Ma, L Stan Leung

Physiology and Pharmacology Publications

BACKGROUND: Cholinergic drugs are known to modulate the response of general anesthesia. However, the sensitivity of isoflurane or other volatile anesthetics after selective lesion of septal cholinergic neurons that project to the hippocampus is not known.

METHODS: Male Long Evans rats had 192 immunoglobulin G-saporin infused into the medial septum (n = 10), in order to selectively lesion cholinergic neurons, whereas control, sham-lesioned rats were infused with saline (n = 12). Two weeks after septal infusion, the hypnotic properties of isoflurane and ketamine were measured using a behavioral endpoint of loss of righting reflex (LORR). Septal lesion was assessed by …

Activation Of Mglur2/3 Receptors In The Ventro-Rostral Prefrontal Cortex Reverses Sensorimotor Gating Deficits Induced By Systemic Nmda Receptor Antagonists., Bridget Valsamis, Michael Chang, Marei Typlt, Susanne Schmid

Brain and Mind Institute Researchers' Publications

Prepulse inhibition (PPI) of acoustic startle is an operational measure of sensorimotor gating, which is disrupted in schizophrenia. NMDA receptor (NMDAR) antagonist induced PPI disruption has become an important pharmacological model for schizophrenia; however, knowledge of the underlying mechanism remains incomplete. This study examines the role of NMDAR in the caudal pontine reticular nucleus (PnC) and the medial prefrontal cortex (mPFC) in NMDARs antagonist induced PPI deficits, as well as the NMDA receptor subtypes involved. We administered the NMDA antagonist MK-801 locally into the caudal pontine reticular formation (PnC), where the PPI mediating pathway converges with the primary startle pathway, …

Sanders-Brown Center on Aging Faculty Publications

The miR-15/107 family comprises a group of 10 paralogous microRNAs (miRNAs), sharing a 5' AGCAGC sequence. These miRNAs have overlapping targets. In order to characterize the expression of miR-15/107 family miRNAs, we employed customized TaqMan Low-Density micro-fluid PCR-array to investigate the expression of miR-15/107 family members, and other selected miRNAs, in 11 human tissues obtained at autopsy including the cerebral cortex, frontal cortex, primary visual cortex, thalamus, heart, lung, liver, kidney, spleen, stomach and skeletal muscle. miR-103, miR-195 and miR-497 were expressed at similar levels across various tissues, whereas miR-107 is enriched in brain samples. We also examined the expression …

A Novel In Vivo Model For Evaluating Functional Restoration Of A Tissue-Engineered Salivary Gland., Swati Pradhan-Bhatt, Daniel A Harrington, Randall L Duncan, Mary C Farach-Carson, Xinqiao Jia, Robert L Witt

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

OBJECTIVES/HYPOTHESIS: To create a novel model for development of a tissue-engineered salivary gland from human salivary gland cells that retains progenitor cell markers useful for treatment of radiation-induced xerostomia.

STUDY DESIGN: A three-dimensional (3D) hyaluronic acid (HA)-based hydrogel scaffold was used to encapsulate primary human salivary gland cells and to obtain organized acini-like spheroids. Hydrogels were implanted into rat models, and cell viability and receptor expression were evaluated.

METHODS: A parotid gland surgical resection model for xenografting was developed. Salivary cells loaded in HA hydrogels formed spheroids and in vitro were implanted in the three-fourths resected parotid bed of athymic …

Corticosterone Administration Up-Regulated Expression Of Norepinephrine Transporter And Dopamine Β-Hydroxylase In Rat Locus Coeruleus And Its Terminal Regions, Yan Fan, Ping Ping Chen, Ying Li, Kui Cui, Daniel M. Noel, Elizabeth D. Cummins, Daniel J. Peterson, Russell W. Brown, Meng-Yang Zhu

ETSU Faculty Works

Stress has been reported to activate the locus coeruleus (LC)-noradrenergic system. In this study, corticosterone (CORT) was orally administrated to rats for 21 days to mimic stress status. In situ hybridization measurements showed that CORT ingestion significantly increased mRNA levels of norepinephrine transporter (NET) and dopamine β-hydroxylase (DBH) in the LC region. Immunofluorescence staining and western blotting revealed that CORT treatment also increased protein levels of NET and DBH in the LC, as well as NET protein levels in the hippocampus, the frontal cortex and the amygdala. However, CORT-induced increase in DBH protein levels only appeared in the hippocampus and …

Targeting Fibroblast Activation Protein In Tumor Stroma With Chimeric Antigen Receptor T Cells Can Inhibit Tumor Growth And Augment Host Immunity Without Severe Toxicity., Liang-Chuan S. Wang, Albert Lo, John Scholler, Jing Sun, Rajrupa S. Majumdar, Veena Kapoor, Michael Antzis, Cody E. Cotner, Laura A. Johnson, Amy C. Durham, Charalambos C. Solomides, Md, Carl H. June, Ellen Puré, Steven M. Albelda

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The majority of chimeric antigen receptor (CAR) T-cell research has focused on attacking cancer cells. Here, we show that targeting the tumor-promoting, nontransformed stromal cells using CAR T cells may offer several advantages. We developed a retroviral CAR construct specific for the mouse fibroblast activation protein (FAP), comprising a single-chain Fv FAP [monoclonal antibody (mAb) 73.3] with the CD8α hinge and transmembrane regions, and the human CD3ζ and 4-1BB activation domains. The transduced muFAP-CAR mouse T cells secreted IFN-γ and killed FAP-expressing 3T3 target cells specifically. Adoptively transferred 73.3-FAP-CAR mouse T cells selectively reduced FAP(hi) stromal cells and inhibited the …

The Differential Interferon Responses Of Two Strains Of Stat1-Deficient Mice Do Not Alter Susceptibility To Hsv-1 And Vsv In Vivo, Sarah Katzenell, Yufei Chen, Zachary M. Parker, David A. Leib

Dartmouth Scholarship

Stat1 is a pivotal transcription factor for generation of the interferon (IFN)-dependent antiviral response. Two Stat1 knockout mouse lines have been previously generated, one deleted the N-terminal domain (ΔNTD) and one in the DNA-binding domain (ΔDBD). These widely-used strains are assumed interchangeable, and both are highly susceptible to various pathogens. In this study, primary cells derived from ΔNTD mice were shown to be significantly more responsive to IFN, and established an antiviral state with greater efficiency than cells derived from ΔDBD mice, following infection with vesicular stomatitis virus and herpes simplex virus type-1. Also, while mice from both strains succumbed …

Roubaud's Circus: Playing With Words And Animals In Les Animaux De Tout Le Monde, Miranda R. Mueller

Master's Theses

It is commonly held that there is a solid, defined line existing between men and animals. This thesis explores the ideological boundary and, through a close examination of Jacques Roubaud’s collection of poetry Les animaux de tout le monde, imagines the line as a fluid structure that can be broken, approached, and multiplied.

In a circus theme following the playful style of Roubaud’s own verses, I include several close readings of poems as well as an analysis of Roubaud’s influence from Lewis Carroll’s nonsense genre, the Fables of Jean de la Fontaine, and Medieval bestiaries in order to create a …

Primate Energy Eexpenditure And Life History, Herman Pontzer, David A. Raichlen, Adam D. Gordon, Kara K. Schroepfer-Walker, Brian Hare, Matthew C. O’Neill, Kathleen M. Muldoon

Dartmouth Scholarship

Humans and other primates are distinct among placental mammals in having exceptionally slow rates of growth, reproduction, and aging. Primates’ slow life history schedules are generally thought to reflect an evolved strategy of allocating energy away from growth and reproduction and toward somatic investment, particularly to the development and maintenance of large brains. Here we examine an alternative explanation: that primates’ slow life histories reflect low total energy expenditure (TEE) (kilocalories per day) relative to other placental mammals. We compared doubly labeled water measurements of TEE among 17 primate species with similar measures for other placental mammals. We found that …

Magnitude Of The Freshwater Turtle Exports From The Us: Long Term Trends And Early Effects Of Newly Implemented Harvest Management Regimes., Ivana Mali, Michael W. Vandewege, Scott K. Davis, Michael R.J. Forstner

CALS Publications

Unregulated commercial harvest remains a major threat for turtles across the globe. Due to continuing demand from Asian markets, a significant number of turtles are exported from the United States of America (US). Beginning in 2007, several southeastern states in the US implemented restrictions on the commercial harvest of turtles, in order to address the unsustainable take. We have summarized freshwater turtle exports from the US between 2002 and 2012 and demonstrated that the magnitude of turtle exports from the US remained high although the exports decreased throughout the decade. Louisiana and California were the major exporters. The majority of …

Rna Viral Metagenome Of Whiteflies Leads To The Discovery And Characterization Of A Whitefly-Transmitted Carlavirus In North America, Karyna Rosario, Heather Capobianco, Terry Fei Fan Ng, Mya Breitbart, Jane E. Polston

Marine Science Faculty Publications

Whiteflies from the Bemisia tabaci species complex have the ability to transmit a large number of plant viruses and are some of the most detrimental pests in agriculture. Although whiteflies are known to transmit both DNA and RNA viruses, most of the diversity has been recorded for the former, specifically for the Begomovirus genus. This study investigated the total diversity of DNA and RNA viruses found in whiteflies collected from a single site in Florida to evaluate if there are additional, previously undetected viral types within the B. tabaci vector. Metagenomic analysis of viral DNA extracted from the whiteflies only …

An Imaging-Based Platform For High-Content, Quantitative Evaluation Of Therapeutic Response In 3d Tumour Models, Jonathan P. Celli, Imran Rizvi, Adam R. Blanden, Iqbal Massodi, Iqbal Massodi, Michael D. Glidden, Brian Pogue, Tayyaba Hasan

Dartmouth Scholarship

While it is increasingly recognized that three-dimensional (3D) cell culture models recapitulate drug responses of human cancers with more fidelity than monolayer cultures, a lack of quantitative analysis methods limit their implementation for reliable and routine assessment of emerging therapies. Here, we introduce an approach based on computational analysis of fluorescence image data to provide high-content readouts of dose-dependent cytotoxicity, growth inhibition, treatment-induced architectural changes and size-dependent response in 3D tumour models. We demonstrate this approach in adherent 3D ovarian and pancreatic multiwell extracellular matrix tumour overlays subjected to a panel of clinically relevant cytotoxic modalities and appropriately designed controls …

Trip/Nopo E3 Ubiquitin Ligase Promotes Ubiquitylation Of Dna Polymerase Η, Heather A. Wallace, Julie A. Merkle, Michael C. Yu, Taloa G. Berg, Ethan Lee, Giovanni Bosco, Laura A. Lee

Dartmouth Scholarship

We previously identified a Drosophila maternal effect-lethal mutant named ‘no poles’ (nopo). Embryos from nopo females undergo mitotic arrest with barrel-shaped, acentrosomal spindles during the rapid cycles of syncytial embryogenesis because of activation of a Chk2-mediated DNA checkpoint. NOPO is the Drosophila homolog of human TNF receptor associated factor (TRAF)-interacting protein (TRIP), which has been implicated in TNF signaling. NOPO and TRIP contain RING domains closely resembling those of known E3 ubiquitin ligases. We herein sought to elucidate the mechanism by which TRIP/NOPO promotes genomic stability by performing a yeast two-hybrid screen to identify potential substrates/interactors. We identified members of …

Redox-Dependent Stability, Protonation, And Reactivity Of Cysteine-Bound Heme Proteins, Fangfang Zhong, George P. Lisi, Daniel P. Collins, John H. Dawson, Ekaterina V. Pletneva

Dartmouth Scholarship

Cysteine-bound hemes are key components of many enzymes and biological sensors. Protonation (deprotonation) of the Cys ligand often accompanies redox transformations of these centers. To characterize these phenomena, we have engineered a series of Thr78Cys/Lys79Gly/Met80X mutants of yeast cytochrome c (cyt c) in which Cys78 becomes one of the axial ligands to the heme. At neutral pH, the protonation state of the coordinated Cys differs for the ferric and ferrous heme species, with Cys binding as a thiolate and a thiol, respectively. Analysis of redox-dependent stability and alkaline transitions of these model proteins, as well as comparisons to Cys …

Spatial Frequency Analysis Of Anisotropic Drug Transport In Tumor Samples, Stewart Russell, Kimberley S. Samkoe, Jason R. Gunn, P Jack Hoopes, Thienan A. Nguyen, Milo J. Russell, Robert R. Alfano, Brian W. Pogue

Dartmouth Scholarship

Directional Fourier spatial frequency analysis was used on standard histological sections to identify salient directional bias in the spatial frequencies of stromal and epithelial patterns within tumor tissue. This directional bias is shown to be correlated to the pathway of reduced fluorescent tracer transport. Optical images of tumor specimens contain a complex distribution of randomly oriented aperiodic features used for neoplastic grading that varies with tumor type, size, and morphology. The internal organization of these patterns in frequency space is shown to provide a precise fingerprint of the extracellular matrix complexity, which is well known to be related to the …

Aortic Aneurysms In Loeys-Dietz Syndrome - A Tale Of Two Pathways?, Frank Davis, Debra L. Rateri, Alan Daugherty

Saha Cardiovascular Research Center Faculty Publications

Loeys-Dietz syndrome (LDS) is a connective tissue disorder that is characterized by skeletal abnormalities, craniofacial malformations, and a high predisposition for aortic aneurysm. In this issue of the JCI, Gallo et al. developed transgenic mouse strains harboring missense mutations in the genes encoding type I or II TGF-β receptors. These mice exhibited several LDS-associated phenotypes. Despite being functionally defective, the mutated receptors enhanced TGF-β signaling in vivo, inferred by detection of increased levels of phosphorylated Smad2. Aortic aneurysms in these LDS mice were ablated by treatment with the Ang II type 1 (AT1) receptor antagonist losartan. The results from this …

Yorke, Robert B. Norgren Jr.

Journal Articles: Genetics, Cell Biology & Anatomy

BACKGROUND: The rhesus macaque (Macaca mulatta) is a key species for advancing biomedical research. Like all draft mammalian genomes, the draft rhesus assembly (rheMac2) has gaps, sequencing errors and misassemblies that have prevented automated annotation pipelines from functioning correctly. Another rhesus macaque assembly, CR_1.0, is also available but is substantially more fragmented than rheMac2 with smaller contigs and scaffolds. Annotations for these two assemblies are limited in completeness and accuracy. High quality assembly and annotation files are required for a wide range of studies including expression, genetic and evolutionary analyses.

RESULTS: We report a new de novo assembly of the …
