Sumo Regulates The Activity Of Smoothened And Costal-2 In Drosophila Hedgehog Signaling, Jie Zhang, Yajuan Liu, Kai Jiang, Jianhang Jia

Markey Cancer Center Faculty Publications

In Hedgehog (Hh) signaling, the GPCR-family protein Smoothened (Smo) acts as a signal transducer that is regulated by phosphorylation and ubiquitination, which ultimately change the cell surface accumulation of Smo. However, it is not clear whether Smo is regulated by other post-translational modifications, such as sumoylation. Here, we demonstrate that knockdown of the small ubiquitin-related modifier (SUMO) pathway components Ubc9 (a SUMO-conjugating enzyme E2), PIAS (a SUMO-protein ligase E3), and Smt3 (the SUMO isoform in Drosophila) by RNAi prevents Smo accumulation and alters Smo activity in the wing. We further show that Hh-induced-sumoylation stabilizes Smo, whereas desumoylation by Ulp1 …

Brelsford, Jordan L Plieskatt, Anna Yakovleva, Amar Jariwala, Brian P Keegan, Jin Peng, Pengjun Xia, Guangzhao Li, Doreen Campbell, Maria Victoria Periago, Rodrigo Correa-Oliveira, Maria Elena Bottazzi, Peter J. Hotez, David Diemert, Jeffrey M. Bethony

Microbiology, Immunology, and Tropical Medicine Faculty Publications

A new generation of vaccines for the neglected tropical diseases (NTDs) have now advanced into clinical development, with the Na-GST-1/Alhydrogel Hookworm Vaccine already being tested in Phase 1 studies in healthy adults. The current manuscript focuses on the often overlooked critical aspects of NTD vaccine product development, more specifically, vaccine stability testing programs. A key measure of vaccine stability testing is "relative potency" or the immunogenicity of the vaccine during storage. As with most NTD vaccines, the Na-GST-1/Alhydrogel Hookworm Vaccine was not developed by attenuation or inactivation of the pathogen (Necator americanus), so conventional methods for measuring relative potency are …

Malondialdehyde-Acetaldehyde (Maa) Adducted Surfactant Protein Induced Lung Inflammation Is Mediated Through Scavenger Receptor A (Sr-A1)., Muna Sapkota, Jane M. Devasure, Kusum K. Kharbanda, Todd A. Wyatt

Journal Articles: Environmental, Agricultural & Occupational Health

BACKGROUND: Co-exposure to cigarette smoke and alcohol leads to the generation of high concentrations of acetaldehyde and malondialdehyde in the lung. These aldehydes being highly electrophilic in nature react with biologically relevant proteins such as surfactant protein D (SPD) through a Schiff base reaction to generate SPD adducted malondialdehyde-acetaldehyde adduct (SPD-MAA) in mouse lung. SPD-MAA results in an increase in lung pro-inflammatory chemokine, keratinocyte chemoattractant (KC), and the recruitment of lung lavage neutrophils. Previous in vitro studies in bronchial epithelial cells and macrophages show that scavenger receptor A (SR-A1/CD204) is a major receptor for SPD-MAA. No studies have yet examined …

Potent Single-Domain Antibodies That Arrest Respiratory Syncytial Virus Fusion Protein In Its Prefusion State, Iebe Rossey, Morgan Gilman, Stephanie Kabeche, Koen Sedeyn, Daniel Wrapp

Dartmouth Scholarship

Human respiratory syncytial virus (RSV) is the main cause of lower respiratory tract infections in young children. The RSV fusion protein (F) is highly conserved and is the only viral membrane protein that is essential for infection. The prefusion conformation of RSV F is considered the most relevant target for antiviral strategies because it is the fusion-competent form of the protein and the primary target of neutralizing activity present in human serum. Here, we describe two llama-derived single-domain antibodies (VHHs) that have potent RSV-neutralizing activity and bind selectively to prefusion RSV F with picomolar affinity. Crystal structures of these VHHs …

Dual-Functional-Tag-Facilitated Protein Labeling And Immobilization, Xinyi Zhang, Wei Lu, Kevin Kwan, Dibakar Bhattacharyya, Yinan Wei

Chemistry Faculty Publications

An important strategy in the construction of biomimetic membranes and devices is to use natural proteins as the functional components for incorporation in a polymeric or nanocomposite matrix. Toward this goal, an important step is to immobilize proteins with high efficiency and precision without disrupting the protein function. Here, we developed a dual-functional tag containing histidine and the non-natural amino acid azidohomoalanine (AHA). AHA is metabolically incorporated into the protein, taking advantage of the Met-tRNA and Met-tRNA synthetase. Histidine in the tag can facilitate metal-affinity purification, whereas AHA can react with an alkyne-functionalized probe or surface via well-established click chemistry. …

Best Practice For Treatment Of Vaccination Side-Effects With Antipyretic And Analgesic Medications, Lacey M. Eden, Meridith G. Lind, Karlen E. Luthy

Student Works

Nurse Practitioners (NPs) are on the frontlines providing parental education regarding vaccines. While there are several reasons for vaccine hesitancy, the potential side-effects of vaccine administration, such as pain and/or elevated temperature, are often cited as a parental concern. According to research, prophylactic administration of an antipyretic/analgesic medication, such as acetaminophen, reduces vaccine side-effects when administered prior to or at the time of vaccination. Additionally, the evidence that prophylactic administration of antipyretic/analgesic medication decreases antibody response to vaccinations is insufficient at this time. Thus, NPs should reassure parents that an antipyretic/analgesic medication can be administered prior to or at the …

Hepatitis C Serosorting Among People Who Inject Drugs In Rural Puerto Rico, Ian Duncan, Ric Curtis, Juan Carlos Reyes, Roberto Abadie, Bilal Khan, Kirk Dombrowski

Publications and Research

Due to the high cost of treatment, preventative measures to limit Hepatitis C (HCV) transmission among people who inject drugs (PWID) are encouraged by many public health officials. A key one of these is serosorting, where PWID select risk partners based on concordant HCV status. Research on the general U.S. population bySmith et al. (2013) found that knowledge of one's own HCV status facilitated serosorting behaviors among PWID, such that respondents with knowledge of their own status were more likely to ask potential partners about their status prior to sharing risk. Our objective was to see if this held true …

Design: We performed a case–control study of adult inpatients receiving ME for pain management.

Settings/Subjects: Adult inpatients receiving ME with a QTc >470 msec (males) and …

Neighborhood Environment And Falls Among Community-Dwelling Older Adults, Emily Nicklett, Matthew Lohman, Matthew Smith

Dartmouth Scholarship

Falls present a major challenge to active aging, but the relationship between neighborhood factors and falls is poorly understood. This study examined the relationship between fall events and neighborhood factors, including neighborhood social cohesion (sense of belonging, trust, friendliness, and helpfulness) and physical environment (vandalism/graffiti, rubbish, vacant/deserted houses, and perceived safety walking home at night).

A Novel Redox Regulator, Mntnbuoe-2-Pyp5+, Enhances Normal Hematopoietic Stem/Progenitor Cell Function, Yanming Zhao, Dustin W. Carroll, Y. You, Luksana Chaiswing, R. Wen, I. Batinic-Haberle, Subbarao Bondada, Ying Liang, Daret K. St Clair

Toxicology and Cancer Biology Faculty Publications

The signaling of reactive oxygen species (ROS) is essential for the maintenance of normal cellular function. However, whether and how ROS regulate stem cells are unclear. Here, we demonstrate that, in transgenic mice expressing the human manganese superoxide dismutase (MnSOD) gene, a scavenger of ROS in mitochondria, the number and function of mouse hematopoietic stem/progenitor cells (HSPC) under physiological conditions are enhanced. Importantly, giving MnTnBuOE-2-PyP⁵⁺(MnP), a redox- active MnSOD mimetic, to mouse primary bone marrow cells or to C57B/L6 mice significantly enhances the number of HSPCs. Mechanistically, MnP reduces superoxide to hydrogen peroxide, which activates intracellular Nrf2 signaling …

Disability In Long-Term Care Residents Explained By Prevalent Geriatric Syndromes, Not Long-Term Care Home Characteristics: A Cross-Sectional Study, Natasha E. Lane, Walter P. Wodchis, Cynthia M. Boyd, Thérèse A. Stukel

Dartmouth Scholarship

Self-care disability is dependence on others to conduct activities of daily living, such as bathing, eating and dressing. Among long-term care residents, self-care disability lowers quality of life and increases health care costs. Understanding the correlates of self-care disability in this population is critical to guide clinical care and ongoing research in Geriatrics. This study examines which resident geriatric syndromes and chronic conditions are associated with residents’ self-care disability and whether these relationships vary across strata of age, sex and cognitive status. It also describes the proportion of variance in residents’ self-care disability that is explained by residents’ geriatric syndromes …

Research Brief: "Age, Race, And Cardiovascular Outcomes In African American Veterans", Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

This study builds on previous research that shows increased risk of cardiovascular disorders among African Americans, and applies that research to African American veterans who receive care at the VHA. For policy and practice, this study suggests various ways that African American veterans can lower their risk of cardiovascular disorders, as well as ways that the VHA can improve the health of veterans. Suggestions for future research include having a larger sample of female veterans, analysis of the factors that contribute to African Americans' higher risk of cardiovascular disorders, and differences in access to health care among African American veterans.
