Department of Cancer Biology Faculty Papers

Prostate cancer is the second leading form of cancer-related death in men. In a subset of prostate cancer patients, increased chemokine signaling IL8 and IL6 correlates with castrate-resistant prostate cancer (CRPC). IL8 and IL6 are produced by prostate epithelial cells and promote prostate cancer cell invasion; however, the mechanisms restraining prostate epithelial cell cytokine secretion are poorly understood. Herein, the cell-fate determinant factor DACH1 inhibited CRPC tumor growth in mice. Using Dach1(fl/fl)/Probasin-Cre bitransgenic mice, we show IL8 and IL6 secretion was altered by approximately 1,000-fold by endogenous Dach1. Endogenous Dach1 is shown to serve as a key endogenous restraint to …

• Established in 2007, the CRH has served over 1,000 refugees of all ages as they resettle in Philadelphia, PA.
• Research about refugee populations generally focuses on infectious disease, women’s health, pediatrics and mental health, with minimal research on the older adult refugee population.
• The objective of this study was to describe the characteristics of the older refugee population served by the CRH, focusing on chronic disease, smoking status, immunization and cancer screening rates, and presence of geriatric syndromes.

A Novel Role For Drebrin In Regulating Progranulin Bioactivity In Bladder Cancer., Shi-Qiong Xu, Simone Buraschi, Alaide Morcavallo, Marco Genua, Tomoaki Shirao, Stephen C Peiper, Leonard G Gomella, Ruth Birbe, Antonino Belfiore, Renato V Iozzo, Andrea Morrione

Department of Urology Faculty Papers

We recently established a critical role for the growth factor progranulin in bladder cancer insofar as progranulin promotes urothelial cancer cell motility and contributes, as an autocrine growth factor, to the transformed phenotype by modulating invasion and anchorage-independent growth. In addition, progranulin expression is upregulated in invasive bladder cancer tissues compared to normal controls. However, the molecular mechanisms of progranulin action in bladder cancer have not been fully elucidated. In this study, we searched for novel progranulin-interacting proteins using pull-down assays with recombinant progranulin and proteomics. We discovered that drebrin, an F-actin binding protein, bound progranulin in urothelial cancer cells. …

Identification And Linkage To Care Of Hcv-Infected Persons In Five Health Centers-Philadelphia, Pennsylvania, 2012-2014, Catelyn Coyle, Mph

JCPH Alumni

Approximately three million persons in the United States are infected with hepatitis C virus (HCV), a blood-borne pathogen that is an increasing cause of liver disease and mortality in the United States (1,2). Treatments for HCV are curative, of short duration, and have few associated side effects (3), increasing the importance of identifying HCV-infected persons. Many persons with HCV infection were infected decades ago, before implementation of prevention measures and most are unaware of their infection, regardless of when it occurred (4). Most newly diagnosed cases are associated with injection drug use (5). Persons born during 1945–1965 have a fivefold …

Adiponectin Attenuates Lung Fibroblasts Activation And Pulmonary Fibrosis Induced By Paraquat., Rong Yao, Yu Cao, Ya-Rong He, Wayne Bond Lau, Zhi Zeng, Zong-An Liang

Department of Emergency Medicine Faculty Papers

Pulmonary fibrosis is one of the most common complications of paraquat (PQ) poisoning, which demands for more effective therapies. Accumulating evidence suggests adiponectin (APN) may be a promising therapy against fibrotic diseases. In the current study, we determine whether the exogenous globular APN isoform protects against pulmonary fibrosis in PQ-treated mice and human lung fibroblasts, and dissect the responsible underlying mechanisms. BALB/C mice were divided into control group, PQ group, PQ + low-dose APN group, and PQ + high-dose APN group. Mice were sacrificed 3, 7, 14, and 21 days after PQ treatment. We compared pulmonary histopathological changes among different …

Evaluation Of A Pharmacist-Led Medication Assessment Used To Identify Prevalence Of And Associations With Polypharmacy And Potentially Inappropriate Medication Use Among Ambulatory Senior Adults With Cancer., Ginah Nightingale, Emily Hajjar, Kristine Swartz, Jocelyn Andrel-Sendecki, Andrew Chapman

College of Pharmacy Faculty Papers

PURPOSE: The use of multiple and/or inappropriate medications in seniors is a significant public health problem, and cancer treatment escalates its prevalence and complexity. Existing studies are limited by patient self-report and medical record extraction compared with a pharmacist-led comprehensive medication assessment.

PATIENTS AND METHODS: We retrospectively examined medication use in ambulatory senior adults with cancer to determine the prevalence of polypharmacy (PP) and potentially inappropriate medication (PIM) use and associated factors. PP was defined as concurrent use of five or more and less than 10 medications, and excessive polypharmacy (EPP) was defined as 10 or more medications. PIMs were …

Consequence Of The Tumor-Associated Conversion To Cyclin D1b., Michael A Augello, Lisa D Berman-Booty, Richard Carr, Akihiro Yoshida, Jeffry L Dean, M J Schiewer, Felix Y Feng, Scott A Tomlins, Erhe Gao, Walter J Koch, Jeffrey L Benovic, John Alan Diehl, Karen E Knudsen

Department of Cancer Biology Faculty Papers

Clinical evidence suggests that cyclin D1b, a variant of cyclin D1, is associated with tumor progression and poor outcome. However, the underlying molecular basis was unknown. Here, novel models were created to generate a genetic switch from cyclin D1 to cyclin D1b. Extensive analyses uncovered overlapping but non-redundant functions of cyclin D1b compared to cyclin D1 on developmental phenotypes, and illustrated the importance of the transcriptional regulatory functions of cyclin D1b in vivo. Data obtained identify cyclin D1b as an oncogene, wherein cyclin D1b expression under the endogenous promoter induced cellular transformation and further cooperated with known oncogenes to promote …

Weaving Quality Improvement And Patient Safety Skills Into All Levels Of Medical Training: An Annotated Bibliography., Eugene Mochan, Phd, Do, David B. Nash, Md, Mba

College of Population Health Faculty Papers

With the launching of the Liaison Committee on Medical Education’s new accreditation Standard ED-19-A in July 2013, a new era in quality improvement/patient safety (QI/PS) has begun. Core curriculum of medical schools must now include multidisciplinary teamwork; that is, inclusion of practitioners and/or students from other health professions. This Standard ED-19-A is harmonious with the earlier Accreditation Council for Graduate Medical Education’s (ACGME) Competency IV.A.5.c., which calls for QI to be integrated into residents’ training curricula. Residents need to be able to determine their strengths and deficiencies. ACGME requires residents to systematically analyze practice using QI methods; to incorporate formative …

Granular Cell Tumor Of The Common Hepatic Duct As An Unusual Cause Of Jaundice In A Hepatitis C Patient: Looking Beyond The Tip Of The Iceberg!, Tripti R. Chopade, Mbbs, Colin L. Smith, Md, Warren R. Maley, Md, Ali A. Siddiqui, Md, David A. Sass, Md

Division of Gastroenterology and Hepatology Faculty Papers

Introduction

Granular cell tumors (GCTs) are rare, benign mesenchymal tumors of Schwann cell origin. Since they were originally described by Abrikossoff in 1926,most GCTs have been described in the dermis, oral area, or subcutaneous tissue of the chest and arms. Only 5%-9% of reported cases have involved the gastrointestinal tract and fewer than 1% of cases have occurred in the biliary tract.Tumors involving the bile duct are difficult to distinguish radiographically from more common etiologies of biliary stricturing, and a tissue diagnosis is difficult to obtain endoscopically. Diagnosis and treatment is most often made via surgical resection.

We studied the roles of autologous (A) and allogeneic (allo) stem cell transplantation (SCT) in the treatment of 134 patients with T cell lymphoma (TCL) at our center. For frontline SCT, 58 patients were studied. The 4-year overall survival (OS) rates for ASCT (n = 47; median age, 49 years) and alloSCT (n = 11; median age, 55 years) groups were 76% and 54%, respectively (P > .05). The 4-year OS rates for first complete remission (CR1) patients were 84% and 83%, respectively. For SCT for relapsed disease, 76 patients were studied (41 with ASCT and 35 with alloSCT). The 4-year …

Transarterial Chemoembolization Is Ineffective For Neuroendocrine Tumors Metastatic To The Caudate Lobe: A Single Institution Review., Lawrence A Shirley, Megan Mcnally, Ravi Chokshi, Natalie Jones, Patrick Tassone, Gregory Guy, Hooman Khabiri, Carl Schmidt, Manisha Shah, Mark Bloomston

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

BACKGROUND: Caudate lobe liver metastases occur commonly in patients with neuroendocrine tumors. It is unknown, however, how these lesions respond to regional therapy and how their presence impacts outcomes. We reviewed our experience treating these lesions using transarterial chemoembolization (TACE).

METHODS: We reviewed radiographic response to TACE in 86 patients with metastatic neuroendocrine tumors to the liver. We determined the impact of caudate lesions on outcomes in comparison to the cohort of patients without caudate lesions, as well as response of caudate lesions to TACE versus lesions elsewhere in the liver.

RESULTS: Caudate lesions were identified in 45 (52%) patients. …

Adolescent And Adult African Americans Have Similar Metabolic Dyslipidemia., Samuel S. Gidding, Scott W. Keith, Bonita Falkner

Department of Pharmacology and Experimental Therapeutics Faculty Papers

BACKGROUND: African Americans (AAs) have lower triglyceride (TG) and higher high-density lipoprotein cholesterol (HDL-C) than other ethnic groups; yet, they also have higher risk for developing diabetes mellitus despite the strong relationship of dyslipidemia with insulin resistance. No studies directly compare adolescents and adults with regard to relationships among dyslipidemia, high-sensitivity C-reactive protein (hs-CRP), and insulin resistance. Here, we compare AA adolescents to adults with regard to the relationships of adiposity-related lipid risk markers (TG-to-HDL ratio and non-HDL-C) with body mass index (BMI), waist circumference (WC), homeostasis model of insulin resistance (HOMA), and hs-CRP.

METHODS: Two cohorts of healthy AA …

Management Of Complications Of Wrist Arthroplasty And Wrist Fusion., Michael P. Gaspar, Patrick M Kane, Eon K. Shin

Department of Orthopaedic Surgery Faculty Papers

The human wrist joint is unique from functional and anatomic standpoints. Numerous articulations exist within the wrist that allow for many options for partial wrist fusion and arthroplasty. In cases of pancarpal disease, fusion or arthroplasty of the entire wrist joint can be performed. Because of the high functional demand of the wrist, many of these surgical options can fail, leading to devastating complications. This article addresses the types of fusions and arthroplasties available for the wrist and discusses the potential complications associated with each. Methods to prevent these complications are presented and those to treat them once they have …

Compensatory Fetal Membrane Mechanisms Between Biglycan And Decorin In Inflammation., Luciana Batalha De Miranda De Araujo, Casie E Horgan, Abraham Aron, Renato V. Iozzo, Beatrice E Lechner

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Preterm premature rupture of fetal membranes (PPROM) is associated with infection, and is one of the most common causes of preterm birth. Abnormal expression of biglycan and decorin, two extracellular matrix proteoglycans, leads to preterm birth and aberrant fetal membrane morphology and signaling in the mouse. In humans and mice, decorin dysregulation is associated with inflammation in PPROM. We therefore investigated the link between biglycan and decorin and inflammation in fetal membranes using mouse models of intraperitoneal Escherichia coli injections superimposed on genetic biglycan and decorin deficiencies. We assessed outcomes in vivo as well as in vitro using quantitative PCR, …

Effects Of Chronic Manganese Exposure On Attention And Working Memory In Non-Human Primates., Jay S. Schneider, Charles Williams, Mark Ault, Tomás R. Guilarte

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Manganese (Mn) is essential for a variety of physiological processes, but at elevated levels, can be neurotoxic. While cognitive dysfunction has been recently appreciated to occur as a result of chronic Mn exposures, it is still unclear as to which cognitive domains are most susceptible to disruption by Mn exposure. We previously described early appearing Mn-induced changes in performance on a paired associate learning task in monkeys chronically exposed to Mn and suggested that performance of this task might be a sensitive tool for detecting cognitive dysfunction resulting from Mn exposure. As chronic Mn exposure has been suggested to be …

Reverse Genetics Of Mononegavirales: How They Work, New Vaccines, And New Cancer Therapeutics., Christian K Pfaller, Roberto Cattaneo, Matthias J. Schnell

Department of Microbiology and Immunology Faculty Papers

The order Mononegavirales includes five families: Bornaviridae, Filoviridae, Nyamaviridae, Paramyxoviridae, and Rhabdoviridae. The genome of these viruses is one molecule of negative-sense single strand RNA coding for five to ten genes in a conserved order. The RNA is not infectious until packaged by the nucleocapsid protein and transcribed by the polymerase and co-factors. Reverse genetics approaches have answered fundamental questions about the biology of Mononegavirales. The lack of icosahedral symmetry and modular organization in the genome of these viruses has facilitated engineering of viruses expressing fluorescent proteins, and these fluorescent proteins have provided important insights about the molecular and cellular …
