Hdac8 And Stat3 Repress Bmf Gene Activity In Colon Cancer Cells, Y Kang, Hui Nian, P Rajendran, W Dashwood, John T. Pinto, E Ho, R Dashwood

NYMC Faculty Publications

Histone deacetylase (HDAC) inhibitors are undergoing clinical trials as anticancer agents, but some exhibit resistance mechanisms linked to anti-apoptotic Bcl-2 functions, such as BH3-only protein silencing. HDAC inhibitors that reactivate BH3-only family members might offer an improved therapeutic approach. We show here that a novel seleno-α-keto acid triggers global histone acetylation in human colon cancer cells and activates apoptosis in a p21-independent manner. Profiling of multiple survival factors identified a critical role for the BH3-only member Bcl-2-modifying factor (Bmf). On the corresponding BMF gene promoter, loss of HDAC8 was associated with signal transducer and activator of transcription 3 (STAT3)/specificity protein …

Provision Of Telemedicine Services By Community Health Centers, Peter Shin, Jessica Sharac, Feygele Jacobs

Health Policy and Management Faculty Publications

The objective of this study was to assess the use of telemedicine services at community health centers. A national survey was distributed to all federally qualified health centers to gather data on their use of health information technology, including telemedicine services. Over a third of responding health centers (37%) provided some type of telemedicine service while 63% provided no telemedicine services. A further analysis that employed ANOVA and chi-square tests to assess differences by the provision of telemedicine services (provided no telemedicine services, provided one telemedicine service, and provided two or more telemedicine services) found that the groups differed by …

Interrater Reliability Of The Wolf Motor Function Test–Functional Ability Scale: Why It Matters, Susan V. Duff, Jiaxue He, Monica A. Nelsen, Christianne J. Lane, Veronica T. Rowe, Steve L. Wolf, Alexander W. Dromerick, Carolee J. Winstein

Physical Therapy Faculty Articles and Research

Background. One important objective for clinical trialists in rehabilitation is determining efficacy of interventions to enhance motor behavior. In part, limitation in the precision of measurement presents a challenge. The few valid, low-cost observational tools available to assess motor behavior cannot escape the variability inherent in test administration and scoring. This is especially true when there are multiple evaluators and raters, as in the case of multisite randomized controlled trials (RCTs). One way to enhance reliability and reduce variability is to implement rigorous quality control (QC) procedures. Objective. This article describes a systematic QC process used to refine …

Kcnj10 Is A Major Type Of K+ Channel In Mouse Corneal Epithelial Cells And Plays A Role In Initiating Egfr Signaling, Lijun Wang, Chengbiao Zhang, Xiaotong Su, Daohong Lin

NYMC Faculty Publications

We used primary mouse corneal epithelial cells (pMCE) to examine the role of Kcnj10 in determining membrane K(+) conductance and cell membrane potential and in regulating EGF/TGFA release. Western blot, immunostaining, and RT-PCR detected the expression of Kcnj10 in mouse cornea. The single channel recording identified the 20-pS inwardly rectifying K(+) channels in pMCE of WT mice, but these channels were absent in Kcnj10(-/-). Moreover, the whole cell recording demonstrates that deletion of Kcnj10 largely abolished the inward K(+) currents and depolarized the cell membrane K(+) reversal potential (an index of the cell membrane potential). This suggests that Kcnj10 is …

The Cost Of Moving Optimally: Kinematic Path Selection., Dinant A Kistemaker, Jeremy D Wong, Paul L Gribble

Brain and Mind Institute Researchers' Publications

It is currently unclear whether the brain plans movement kinematics explicitly or whether movement paths arise implicitly through optimization of a cost function that takes into account control and/or dynamic variables. Several cost functions are proposed in the literature that are very different in nature (e.g., control effort, torque change, and jerk), yet each can predict common movement characteristics. We set out to disentangle predictions of the different variables using a combination of modeling and empirical studies. Subjects performed goal-directed arm movements in a force field (FF) in combination with visual perturbations of seen hand position. This FF was designed …

Gucy2c Lysosomotropic Endocytosis Delivers Immunotoxin Therapy To Metastatic Colorectal Cancer., Glen P Marszalowicz, Adam E. Snook, Michael Sullivan Magee, Dante Merlino, Lisa D Berman-Booty, Scott A Waldman

Department of Pharmacology and Experimental Therapeutics Faculty Papers

The emergence of targeted cancer therapy has been limited by the paucity of determinants which are tumor-specific and generally associated with disease, and have cell dynamics which effectively deploy cytotoxic payloads. Guanylyl cyclase C (GUCY2C) may be ideal for targeting because it is normally expressed only in insulated barrier compartments, including intestine and brain, but over-expressed by systemic metastatic colorectal tumors. Here, we reveal that GUCY2C rapidly internalizes from the cell surface to lysosomes in intestinal and colorectal cancer cells. Endocytosis is independent of ligand binding and receptor activation, and is mediated by clathrin. This mechanism suggests a design for …

Visualization-Aided Classification Ensembles Discriminate Lung Adenocarcinoma And Squamous Cell Carcinoma Samples Using Their Gene Expression Profiles, Ao Zhang, Chi Wang, Shiji Wang, Liang Li, Zhongmin Liu, Suyan Tian

Markey Cancer Center Faculty Publications

INTRODUCTION: The widespread application of microarray experiments to cancer research is astounding including lung cancer, one of the most common fatal human tumors. Among non-small cell lung carcinoma (NSCLC), there are two major histological types of NSCLC, adenocarcinoma (AC) and squamous cell carcinoma (SCC).

RESULTS: In this paper, we proposed to integrate a visualization method called Radial Coordinate Visualization (Radviz) with a suitable classifier, aiming at discriminating two NSCLC subtypes using patients' gene expression profiles. Our analyses on simulated data and a real microarray dataset show that combining with a classification method, Radviz may play a role in …

Calcium Supplementation Increases Blood Creatinine Concentration In A Randomized Controlled Trial, Elizabeth L. L. Barry, Leila A. A. Mott, Michal L. L. Melamed, Judith R. Rees, Anastasia Ivanova, Robert S. Sandler, Dennis J. Ahnen, Robert S. Bresalier, Robert W. Summers, Roberd M. Bostick, John A. Baron

Dartmouth Scholarship

Background: Calcium supplements are widely used among older adults for osteoporosis prevention and treatment. However, their effect on creatinine levels and kidney function has not been well studied.

Methods: We investigated the effect of calcium supplementation on blood creatinine concentration in a randomized controlled trial of colorectal adenoma chemoprevention conducted between 2004–2013 at 11 clinical centers in the United States. Healthy participants (N=1,675) aged 45–75 with a history of colorectal adenoma were assigned to daily supplementation with calcium (1200 mg, as carbonate), vitamin D3 (1000 IU), both, or placebo for three or five years. Changes in blood creatinine and total …

Naturally Occurring Peer Support Through Social Media: The Experiences Of Individuals With Severe Mental Illness Using Youtube, John A. Naslund, Stuart W. Grande, Kelly A. Aschbrenner, Glyn Elwyn

Dartmouth Scholarship

Increasingly, people with diverse health conditions turn to social media to share their illness experiences or seek advice from others with similar health concerns. This unstructured medium may represent a platform on which individuals with severe mental illness naturally provide and receive peer support. Peer support includes a system of mutual giving and receiving where individuals with severe mental illness can offer hope, companionship, and encouragement to others facing similar challenges. In this study we explore the phenomenon of individuals with severe mental illness uploading videos to YouTube, and posting and responding to comments as a form of naturally occurring …

This review provides an overview of the epidemiology, pathophysiology, natural history, clinical presentation, diagnosis, and management of AVMs. The authors discussed the imaging techniques available for detecting AVMs with regard to the advantages and disadvantages of each imaging modality. Furthermore, this review paper discusses the factors that must be considered for the most appropriate management strategy (based on the current evidence in the literature) and the risks and benefits …

A Case Of Cutaneous Larva Migrans Presenting In A Pregnant Patient., Kasie Kudrewicz, Kylee N Crittenden, Alison Himes

Women’s Health Articles

Cutaneous larva migrans (CLM) is a pruritic dermatitis caused by migration of the animal hookworm larvae into the epidermis. We present a case of CLM in a 31-year-old pregnant woman. The treatment of CLM relies on antihelminthic agents, such as thiabendazole, albendazole, and ivermectin. This case was interesting in that the standard treatment options previously mentioned were contraindicated owing to the patient's pregnancy. Cryotherapy with liquid nitrogen resulted in complete resolution of her lesion and symptoms.

The Anniston Community Health Survey was a community-based cross-sectional study of Anniston, Alabama, residents who live in close proximity to a former PCB production facility to identify factors associated with serum PCB levels. The survey comprises 765 Anniston residents who completed a questionnaire interview and provided a blood sample for analysis in 2005–2007. Several reports based on data from the Anniston survey have been previously published, including associations between PCB exposure and diabetes and blood pressure. In this study we examine demographic, behavioral, dietary, and occupational characteristics of Anniston survey participants as predictors of serum PCB concentrations. Of the 765 …

Temporal And Stochastic Control Of Staphylococcus Aureus Biofilm Development., Derek E. Moormeier, Jeffrey L. Bose, Alexander R. Horswill, Kenneth W. Bayles

Journal Articles: Pathology and Microbiology

Biofilm communities contain distinct microniches that result in metabolic heterogeneity and variability in gene expression. Previously, these niches were visualized within Staphylococcus aureus biofilms by observing differential expression of the cid and lrg operons during tower formation. In the present study, we examined early biofilm development and identified two new stages (designated "multiplication" and "exodus") that were associated with changes in matrix composition and a distinct reorganization of the cells as the biofilm matured. The initial attachment and multiplication stages were shown to be protease sensitive but independent of most cell surface-associated proteins. Interestingly, after 6 h of growth, an …

Mechanisms Of Ash Resistance To Emerald Ash Borer: Progress And Gaps, Caterina Villari, Justin G.A. Whitehill, Don Cipollini, Daniel A. Herms, Pierluigi Bonello

Biological Sciences Faculty Publications

The emerald ash borer (EAB) invasion of North America has caused widespread mortality of native ash, and is threatening the native ash resources. As a consequence of its devastating impact, EAB has caught the attention of the scientific community, and several studies have focused on different aspects of the biology and behavior of this pest, including its interaction with host defenses. Here we present a review of the published literature on mechanisms of ash resistance to EAB, the understanding of which, despite starting from a tabula rasa, has achieved significant progress in the last few years.

Cost Estimates Of Foundational Public Health Capabilities: Pilot Test Results Of An Expert Consensus Methodology In Kentucky, C. B. Mamaril, Glen P. Mays

Health Management and Policy Presentations

The Institute of Medicine's 2012 report on U.S. public health financing recommended research to identify the components and costs of a "minimum package" of public health services and foundational capabilities to be made available in every U.S. community. We present results from pilot testing of a proposed methodology for estimating the costs and resource requirements for a set of foundational public health capabilities identified by the Public Health Leadership Forum. Using pilot data from Kentucky public health settings, we estimate both current and projected costs under a range of assumptions about the resources required to fully implement the capabilities at …

Mmu-Mir-615-3p Regulates Lipoapoptosis By Inhibiting C/Ebp Homologous Protein., Yasuhiro Miyamoto, Amy S Mauer, Swarup Kumar, Justin L. Mott, Harmeet Malhi

Journal Articles: Biochemistry & Molecular Biology

Lipoapoptosis occurring due to an excess of saturated free fatty acids such as palmitate is a key pathogenic event in the initiation of nonalcoholic fatty liver disease. Palmitate loading of cells activates the endoplasmic reticulum stress response, including induction of the proapoptotic transcription factor C/EBP homologous protein (CHOP). Furthermore, the loss of microRNAs is implicated in regulating apoptosis under conditions of endoplasmic reticulum (ER) stress. The aim of this study was to identify specific microRNAs regulating CHOP expression during palmitate-induced ER stress. Five microRNAs were repressed under palmitate-induced endoplasmic reticulum stress conditions in hepatocyte cell lines (miR-92b-3p, miR-328-3p, miR-484, miR-574-5p, …

Sitagliptin Associated Pancreatic Carcinoma: A Review Of The Fda Aers Database, Angela Nagel, Gabriela Cipriano, Nabila Ahmed-Sarwar, Robbert Van Manen, Jack Brown

Pharmacy Faculty/Staff Publications

Purpose: Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor used in the treatment of type 2 diabetes mellitus in adults, as adjunct to diet and exercise to improve glycemic control. During phase III studies, sitagliptin was shown to cause toxicity to the pancreas, including pancreatitis. To date there is limited information available regarding its association with pancreatic carcinoma. Our goal was to qualitatively and quantitatively review available information in the AERS database in order to provide clinicians with a general understanding of the comparative occurrence of sitagliptin use and pancreatic carcinoma and any clinically relevant characteristics that may be useful in …

Tendinopathy: Setting The Record Straight, Craig Nuttall, Ryan Rasmussen

Faculty Publications

Tendinopathy is a commonly diagnosed injury. Traditionally, tendinopathy was considered to be caused by an inflammatory process. It is now known that a majority of tendinopathies are caused by tendinosis, a failed healing response resulting in a degenerated tendon. The recurrent nature of tendinopathies can present a challenge for the health care provider and be very frustrating for the patient. There are several principles that should be followed when treating tendinopathies. These principles include rest, ice, eccentric exercises, and avoidance of corticosteroid injections. Proper treatment of tendinopathies can lead to optimal healing and decrease the risk of recurrence.

Explaining Racial/Ethnic Disparities In Use Of High-Volume Hospitals: Decision-Making Complexity And Local Hospital Environments, Karl Kronebusch, Bradford H. Gray, Mark Schlesinger

Publications and Research

Racial/ethnic minorities are less likely to use higher-quality hospitals than whites. We propose that a higher level of informationrelated complexity in their local hospital environments compounds the effects of discrimination and more limited access to services, contributing to racial/ethnic disparities in hospital use. While minorities live closer than whites to high-volume hospitals, minorities also face greater choice complexity and live in neighborhoods with lower levels of medical experience. Our empirical results reveal that it is generally the overall context associated with proximity, choice complexity, and local experience, rather than differential sensitivity to these factors, that provides a partial explanation of …
