Requirement For Golgi-Localized Pi(4)P In Fusion Of Copii Vesicles With Golgi Compartments, Andres Lorente-Rodriguez, Charles Barlowe

Dartmouth Scholarship

The role of specific membrane lipids in transport between endoplasmic reticulum (ER) and Golgi compartments is poorly understood. Using cell-free assays that measure stages in ER-to-Golgi transport, we screened a variety of enzyme inhibitors, lipid-modifying enzymes, and lipid ligands to investigate requirements in yeast. The pleckstrin homology (PH) domain of human Fapp1, which binds phosphatidylinositol-4-phosphate (PI(4)P) specifically, was a strong and specific inhibitor of anterograde transport. Analysis of wild type and mutant PH domain proteins in addition to recombinant versions of the Sac1p phosphoinositide-phosphatase indicated that PI(4)P was required on Golgi membranes for fusion with coat protein complex II (COPII) …

Biological Rationale For The Use Of Dna Methyltransferase Inhibitors As New Strategy For Modulation Of Tumor Response To Chemotherapy And Radiation., Giovanni L Gravina, Claudio Festuccia, Francesco Marampon, Vladimir M Popov, Richard G Pestell, Bianca M Zani, Vincenzo Tombolini

Kimmel Cancer Center Faculty Papers

Epigenetic modifications play a key role in the patho-physiology of many tumors and the current use of agents targeting epigenetic changes has become a topic of intense interest in cancer research. DNA methyltransferase (DNMT) inhibitors represent a promising class of epigenetic modulators. Research performed yielded promising anti-tumorigenic activity for these agents in vitro and in vivo against a variety of hematologic and solid tumors. These epigenetic modulators cause cell cycle and growth arrest, differentiation and apoptosis. Rationale for combining these agents with cytotoxic therapy or radiation is straightforward since the use of DNMT inhibitor offers greatly improved access for cytotoxic …

Supply Sensitive Services In Swiss Ambulatory Care: An Analysis Of Basic Health Insurance Records For 2003-2007, André Busato, Pius Matter, Beat Künzi, David C. Goodman

Dartmouth Scholarship

Swiss ambulatory care is characterized by independent, and primarily practice-based, physicians, receiving fee for service reimbursement. This study analyses supply sensitive services using ambulatory care claims data from mandatory health insurance. A first research question was aimed at the hypothesis that physicians with large patient lists decrease their intensity of services and bill less per patient to health insurance, and vice versa: physicians with smaller patient lists compensate for the lack of patients with additional visits and services. A second research question relates to the fact that several cantons are allowing physicians to directly dispense drugs to patients ('self-dispensation') whereas …

Mouse Cd8alpha+ Dcs And Human Bdca3+ Dcs Are Major Producers Of Ifn-Lambda In Response To Poly Ic., Henning Lauterbach, Barbara Bathke, Stefanie Gilles, Claudia Traidl-Hoffmann, Christian A.

School of Biomedical Sciences

Polyinosinic:polycytidylic acid (poly IC), a double-stranded RNA, is an effective adjuvant in vivo. IFN-λs (also termed IL-28/29) are potent immunomodulatory and antiviral cytokines. We demonstrate that poly IC injection in vivo induces large amounts of IFN-λ, which depended on hematopoietic cells and the presence of TLR3 (Toll-like receptor 3), IRF3 (IFN regulatory factor 3), IRF7, IFN-I receptor, Fms-related tyrosine kinase 3 ligand (FL), and IRF8 but not on MyD88 (myeloid differentiation factor 88), Rig-like helicases, or lymphocytes. Upon poly IC injection in vivo, the IFN-λ production by splenocytes segregated with cells phenotypically resembling CD8α(+) conventional dendritic cells (DCs [cDCs]). In …

Carhsp1 Is Required For Effective Tumor Necrosis Factor Alpha Mrna Stabilization And Localizes To Processing Bodies And Exosomes, Jason R. Pfeiffer, Bethany L. Mcavoy, Ryan E. Fecteau, Kristen M. Deleault, Seth A. Brooks

Dartmouth Scholarship

Tumor necrosis factor alpha (TNF-α) is a critical mediator of inflammation, and its production is tightly regulated, with control points operating at nearly every step of its biosynthesis. We sought to identify uncharacterized TNF-α 3' untranslated region (3'UTR)-interacting proteins utilizing a novel screen, termed the RNA capture assay. We identified CARHSP1, a cold-shock domain-containing protein. Knockdown of CARHSP1 inhibits TNF-α protein production in lipopolysaccharide (LPS)-stimulated cells and reduces the level of TNF-α mRNA in both resting and LPS-stimulated cells. mRNA stability assays demonstrate that CARHSP1 knockdown decreases TNF-α mRNA stability from a half-life (t(1/2)) of 49 min to a t(1/2) …

Intestinal Epithelial Serum Amyloid A Modulates Bacterial Growth In Vitro And Pro-Inflammatory Responses In Mouse Experimental Colitis, Erik R.M. Eckhardt, Jassir Witta, Jian Zhong, Razvan Arsenescu, Violeta Arsenescu, Yu Wang, Sarbani Ghoshal, Marcielle C. De Beer, Frederick C. De Beer, Willem J.S. De Villiers

Internal Medicine Faculty Publications

BACKGROUND: Serum Amyloid A (SAA) is a major acute phase protein of unknown function. SAA is mostly expressed in the liver, but also in other tissues including the intestinal epithelium. SAA reportedly has anti-bacterial effects, and because inflammatory bowel diseases (IBD) result from a breakdown in homeostatic interactions between intestinal epithelia and bacteria, we hypothesized that SAA is protective during experimental colitis.

METHODS: Intestinal SAA expression was measured in mouse and human samples. Dextran sodium sulfate (DSS) colitis was induced in SAA 1/2 double knockout (DKO) mice and in wildtype controls. Anti-bacterial effects of SAA1/2 were tested in intestinal epithelial …

Dysregulation Of The Mitogen Granulin In Human Cancer Through The Mir-15/107 Microrna Gene Group, Wang-Xia Wang, Natasha Kyprianou, Xiaowei Wang, Peter T. Nelson

Pathology and Laboratory Medicine Faculty Publications

Granulin (GRN) is a potent mitogen and growth factor implicated in many human cancers, but its regulation is poorly understood. Recent findings indicate that GRN is regulated strongly by the microRNA miR-107, which functionally overlaps with miR-15, miR-16, and miR-195 due to a common 5′ sequence critical for target specificity. In this study, we queried whether miR-107 and paralogs regulated GRN in human cancers. In cultured cells, anti-argonaute RNA coimmunoprecipitation with downstream microarray analyses indicates that GRN mRNA is directly targeted by numerous miR-15/107 miRNAs. We further tested this association in human tumors. MiR-15 and miR-16 are known to be …

Automated Classification Of Breast Pathology Using Local Measures Of Broadband Reflectance, Ashley M. Laughney, Venkataramanan Krishnaswamy, Pilar Beatriz Garcia-Allende, Olga M. Conde, Wendy A. Wells, Keith D. Paulsen, Brian W. Pogue

Dartmouth Scholarship

We demonstrate that morphological features pertinent to a tissue's pathology may be ascertained from localized measures of broadband reflectance, with a mesoscopic resolution (100-μm lateral spot size) that permits scanning of an entire margin for residual disease. The technical aspects and optimization of a k-nearest neighbor classifier for automated diagnosis of pathologies are presented, and its efficacy is validated in 29 breast tissue specimens. When discriminating between benign and malignant pathologies, a sensitivity and specificity of 91 and 77% was achieved. Furthermore, detailed subtissue-type analysis was performed to consider how diverse pathologies influence scattering response and overall classification efficacy. The …

Nfκb Activation And Stimulation Of Chemokine Production In Normal Human Macrophages By The Gadolinium-Based Magnetic Resonance Contrast Agent Omniscan: Possible Role In The Pathogenesis Of Nephrogenic Systemic Fibrosis., Francesco Del Galdo, Peter J Wermuth, Sankar Addya, Paolo Fortina, Sergio A Jimenez

Jefferson Institute of Molecular Medicine Papers and Presentations

OBJECTIVE: Nephrogenic systemic fibrosis (NSF) is a generalised fibrotic disorder occurring in certain individuals with renal insufficiency exposed to gadolinium-based contrast agents (GdBCA) for MRI. Histopathological examination of affected tissues shows increased numbers of activated macrophages. To elucidate the mechanisms responsible for macrophage activation, the effects of the GdBCA Omniscan on normal human macrophage global gene expression, chemokine production and nuclear factor κB (NFκB) activation was examined.

METHODS: Normal human monocyte-derived macrophages were incubated with Omniscan (50 mM) and their gene expression analysed by microarrays and real-time PCR. Macrophage chemokine production was assayed by multiplex ELISA. NFκB activation was assessed …

Subglottic Secretion Aspiration In The Prevention Of Ventilator-Associated Pneumonia: A Review Of The Literature., Rachel Scherzer

Jefferson Hospital Staff Papers and Presentations

Ventilator-associated pneumonia is a common nosocomial infection that results in both negative patient outcomes and increased health care costs. Recently, many efforts have been targeted at ventilator-associated pneumonia prevention, including the practice of subglottic secretion aspiration. Six randomized control studies examining the effectiveness of subglottic secretion aspiration in the prevention of ventilator-associated pneumonia were reviewed for this article. Results consistently show that subglottic secretion aspiration significantly reduces the incidence of ventilator-associated pneumonia in a variety of patient populations. Despite these findings, this practice is limited in clinical settings. This clinical practice should be implemented in individuals requiring mechanical ventilation to …

Wild-Type And Mutant Sod1 Share An Aberrant Conformation And A Common Pathogenic Pathway In Als., Daryl A Bosco, Gerardo Morfini, N Murat Karabacak, Yuyu Song, Francois Gros-Louis, Piera Pasinelli, Holly Goolsby, Benjamin A Fontaine, Nathan Lemay, Diane Mckenna-Yasek, Matthew P Frosch, Jeffrey N Agar, Jean-Pierre Julien, Scott T Brady, Robert H Brown

Farber Institute for Neuroscience Faculty Papers

Many mutations confer one or more toxic function(s) on copper/zinc superoxide dismutase 1 (SOD1) that impair motor neuron viability and cause familial amyotrophic lateral sclerosis (FALS). Using a conformation-specific antibody that detects misfolded SOD1 (C4F6), we found that oxidized wild-type SOD1 and mutant SOD1 share a conformational epitope that is not present in normal wild-type SOD1. In a subset of human sporadic ALS (SALS) cases, motor neurons in the lumbosacral spinal cord were markedly C4F6 immunoreactive, indicating that an aberrant wild-type SOD1 species was present. Recombinant, oxidized wild-type SOD1 and wild-type SOD1 immunopurified from SALS tissues inhibited kinesin-based fast axonal …

Pp32 (Anp32a) Expression Inhibits Pancreatic Cancer Cell Growth And Induces Gemcitabine Resistance By Disrupting Hur Binding To Mrnas., Timothy K Williams, Christina L Costantino, Nikolai A Bildzukewicz, Nathan G Richards, David W Rittenhouse, Lisa Einstein, Joseph A Cozzitorto, Judith C Keen, Abhijit Dasgupta, Myriam Gorospe, Gregory E Gonye, Charles J Yeo, Agnieszka K Witkiewicz, Jonathan R Brody

Department of Surgery Faculty Papers

The expression of protein phosphatase 32 (PP32, ANP32A) is low in poorly differentiated pancreatic cancers and is linked to the levels of HuR (ELAV1), a predictive marker for gemcitabine response. In pancreatic cancer cells, exogenous overexpression of pp32 inhibited cell growth, supporting its long-recognized role as a tumor suppressor in pancreatic cancer. In chemotherapeutic sensitivity screening assays, cells overexpressing pp32 were selectively resistant to the nucleoside analogs gemcitabine and cytarabine (ARA-C), but were sensitized to 5-fluorouracil; conversely, silencing pp32 in pancreatic cancer cells enhanced gemcitabine sensitivity. The cytoplasmic levels of pp32 increased after cancer cells are treated with certain stressors, …

Image Guided Near-Infrared Spectroscopy Of Breast Tissue In Vivo Using Boundary Element Method, Subhadra Srinivasan, Colin M. Carpenter, Hamid R. Ghadyani, Senate J. Taka, Peter A. Kaufman, Roberta M. Diflorio-Alexander, Wendy A. Wells, Brian W. Pogue, Keith D. Paulsen

Dartmouth Scholarship

We demonstrate quantitative functional imaging using image-guided near-infrared spectroscopy (IG-NIRS) implemented with the boundary element method (BEM) for reconstructing 3-D optical property estimates in breast tissue in vivo. A multimodality MRI-NIR system was used to collect measurements of light reflectance from breast tissue. The BEM was used to model light propagation in 3-D based only on surface discretization in order to reconstruct quantitative values of total hemoglobin (HbT), oxygen saturation, water, and scatter. The technique was validated in experimental measurements from heterogeneous breast-shaped phantoms with known values and applied to a total of seven subjects comprising six healthy individuals …

Should We Be Concerned About Jejunoileal Atresia During Repair Of Duodenal Atresia?, Shawn D. St Peter, Danny C. Little, Katherine A. Barsness, Daniel R. Copeland, Casey M. Calkins, Suzanne Yoder, Steve S. Rothenberg, Saleem Islam, Kuojen Tsao, Daniel J. Ostlie

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: During repair for duodenal atresia, it has been emphasized that inspection of the small bowel to identify a second atresia is required. The laparoscopic approach for repair of duodenal atresia has been criticized for its limitation to perform this step. Given that duodenal atresia and jejunoileal atresias do not share common embryologic origins, we question the validity of this concern. Therefore, we conducted a multicenter retrospective review of duodenal atresia patients to quantify the incidence of jejunoileal atresia in this population.

METHODS: After institutional review board approval (IRB #07-12-187X), a retrospective review was conducted on all patients who have …

Ms4a4b, A Cd20 Homologue In T Cells, Inhibits T Cell Propagation By Modulation Of Cell Cycle., Hui Xu, Yaping Yan, Mark S Williams, Gregory B Carey, Jingxian Yang, Hongmei Li, Guang-Xian Zhang, Abdolmohamad Rostami

Department of Neurology Faculty Papers

MS4a4B, a CD20 homologue in T cells, is a novel member of the MS4A gene family in mice. The MS4A family includes CD20, FcεRIβ, HTm4 and at least 26 novel members that are characterized by their structural features: with four membrane-spanning domains, two extracellular domains and two cytoplasmic regions. CD20, FcεRIβ and HTm4 have been found to function in B cells, mast cells and hematopoietic cells respectively. However, little is known about the function of MS4a4B in T cell regulation. We demonstrate here that MS4a4B negatively regulates mouse T cell proliferation. MS4a4B is highly expressed in primary T cells, natural …

Cyanidin-3-Glucoside Inhibits Ethanol-Induced Invasion Of Breast Cancer Cells Overexpressing Erbb2, Mei Xu, Kimberly A. Bower, Siying Wang, Jacqueline A. Frank, Gang Chen, Min Ding, Shiow Wang, Xianglin Shi, Zunji Ke, Jia Luo

Internal Medicine Faculty Publications

BACKGROUND: Ethanol is a tumor promoter. Both epidemiological and experimental studies suggest that ethanol may enhance the metastasis of breast cancer cells. We have previously demonstrated that ethanol increased the migration/invasion of breast cancer cells expressing high levels of ErbB2. Amplification of ErbB2 is found in 20-30% of breast cancer patients and is associated with poor prognosis. We sought to identify agents that can prevent or ameliorate ethanol-induced invasion of breast cancer cells. Cyanidin-3-glucoside (C3G), an anthocyanin present in many vegetables and fruits, is a potent natural antioxidant. Ethanol exposure causes the accumulation of intracellular reactive oxygen species (ROS). This …

Limitations Of The Knee Society Score In Evaluating Outcomes Following Revision Total Knee Arthroplasty., Elie Ghanem, Ian Pawasarat, Adam Lindsay, Lauren May, Khalid Azzam, Ashish Joshi, Javad Parvizi

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: Traditionally, the results of revision total knee arthroplasty have been determined with use of surgeon-based measures such as the Knee Society rating system. Recently, outcome and quality-of-life measures have shifted toward a greater emphasis on patient-based evaluation. The aim of our study was to determine the validity and responsiveness of the Knee Society rating system compared with the Short Form-36 health survey (SF-36), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and a four-question 4-point Likert scale satisfaction questionnaire following revision total knee arthroplasty.

METHODS: A total of 152 patients underwent revision total knee arthroplasty at our institution, between …

Vitamin D Binding Protein-Macrophage Activating Factor Directly Inhibits Proliferation, Migration, And Upar Expression Of Prostate Cancer Cells, Kalvin J. Gregory, Bing Zhao, Diane R. Bielenberg, Sami Dridi, Jason Wu, Weihua Jiang, Bin Huang, Steven Pirie-Shepherd, Michael Fannon

Ophthalmology and Visual Science Faculty Publications

BACKGROUND: Vitamin D binding protein-macrophage activating factor (DBP-maf) is a potent inhibitor of tumor growth. Its activity, however, has been attributed to indirect mechanisms such as boosting the immune response by activating macrophages and inhibiting the blood vessel growth necessary for the growth of tumors.

METHODS AND FINDINGS: In this study we show for the first time that DBP-maf exhibits a direct and potent effect on prostate tumor cells in the absence of macrophages. DBP-maf demonstrated inhibitory activity in proliferation studies of both LNCaP and PC3 prostate cancer cell lines as well as metastatic clones of these cells. Flow cytometry …

Differential Regulation Of P53 Function By The N-Terminal Δnp53 And Δ113p53 Isoforms In Zebrafish Embryos., William R Davidson, Csaba Kari, Qing Ren, Borbala Daroczi, Adam P Dicker, Ulrich Rodeck

Department of Radiation Oncology Faculty Papers

BACKGROUND: The p53 protein family coordinates stress responses of cells and organisms. Alternative promoter usage and/or splicing of p53 mRNA gives rise to at least nine mammalian p53 proteins with distinct N- and C-termini which are differentially expressed in normal and malignant cells. The human N-terminal p53 variants contain either the full-length (FL), or a truncated (ΔN/Δ40) or no transactivation domain (Δ133) altogether. The functional consequences of coexpression of the different p53 isoforms are poorly defined. Here we investigated functional aspects of the zebrafish ΔNp53 ortholog in the context of FLp53 and the zebrafish Δ133p53 ortholog (Δ113p53) coexpressed in the …

Differential Effects Of Mindful Breathing, Progressive Muscle Relaxation, And Loving-Kindness Meditation On Decentering And Negative Reactions To Repetitive Thoughts., Greg Feldman, Jeffrey M. Greeson, Joanna Senville

College of Science & Mathematics Departmental Research

Decentering has been proposed as a potential mechanism of mindfulness-based interventions but has received limited empirical examination to date in experimental studies comparing mindfulness meditation to active comparison conditions. In the present study, we compared the immediate effects of mindful breathing (MB) to two alternative stress-management techniques: progressive muscle relaxation (PMR) and loving-kindness meditation (LKM) to test whether decentering is unique to mindfulness meditation or common across approaches. Novice meditators (190 female undergraduates) were randomly assigned to complete one of three 15-min stress-management exercises (MB, PMR, or LKM) presented by audio recording. Immediately after the exercise, participants completed measures of …

Assessment Of Tobacco Dependence Curricula In U.S. Dental Hygiene Programs, Joan M. Davis, Anne Koerber

Journal Articles

Tobacco dependence education (TDE) continues to be a vital component of dental hygiene curricula-made even more important by the fact that tobacco cessation in adults in the United States has stagnated over the past ten years. This study was undertaken to assess the salient characteristics of TDE in U.S. dental hygiene programs. A fifty-one question survey was mailed to the program directors of all 283 accredited dental hygiene programs during the 2007-08 school year (this number does not include the programs in Illinois, which were excluded since they had participated in a previous study). A total of 187 schools returned …
