Disc In Flames: Roles Of Tnf-Α And Il-1Β In Intervertebral Disc Degeneration., Z I Johnson, Z R Schoepflin, H Choi, I M Shapiro, M V Risbud

Department of Orthopaedic Surgery Faculty Papers

The intervertebral disc is an important mechanical structure that allows range of motion of the spinal column. Degeneration of the intervertebral disc--incited by aging, traumatic insult, genetic predisposition, or other factors--is often defined by functional and structural changes in the tissue, including excessive breakdown of the extracellular matrix, increased disc cell senescence and death, as well as compromised biomechanical function of the tissue. Intervertebral disc degeneration is strongly correlated with low back pain, which is a highly prevalent and costly condition, significantly contributing to loss in productivity and health care costs. Disc degeneration is a chronic, progressive condition, and current …

Lysyl Hydroxylase 3 Localizes To Epidermal Basement Membrane And Is Reduced In Patients With Recessive Dystrophic Epidermolysis Bullosa., Stephen A Watt, Jasbani H S Dayal, Sheila Wright, Megan Riddle, Celine Pourreyron, James R Mcmillan, Roy M Kimble, Marco Prisco, Ulrike Gartner, Emma Warbrick, W H Irwin Mclean, Irene M Leigh, John A Mcgrath, Julio C Salas-Alanis, Jakub Tolar, Andrew P South

Department of Dermatology and Cutaneous Biology Faculty Papers

Recessive dystrophic epidermolysis bullosa (RDEB) is caused by mutations in COL7A1 resulting in reduced or absent type VII collagen, aberrant anchoring fibril formation and subsequent dermal-epidermal fragility. Here, we identify a significant decrease in PLOD3 expression and its encoded protein, the collagen modifying enzyme lysyl hydroxylase 3 (LH3), in RDEB. We show abundant LH3 localising to the basement membrane in normal skin which is severely depleted in RDEB patient skin. We demonstrate expression is in-part regulated by endogenous type VII collagen and that, in agreement with previous studies, even small reductions in LH3 expression lead to significantly less secreted LH3 …

Statins Increase Plasminogen Activator Inhibitor Type 1 Gene Transcription Through A Pregnane X Receptor Regulated Element., Frederick M Stanley, Kathryn M Linder, Timothy J Cardozo

Department of Medical Genetics Faculty Papers

Plasminogen activator inhibitor type 1 (PAI-1) is a multifunctional protein that has important roles in inflammation and wound healing. Its aberrant regulation may contribute to many disease processes such as heart disease. The PAI-1 promoter is responsive to multiple inputs including cytokines, growth factors, steroids and oxidative stress. The statin drugs, atorvastatin, mevastatin and rosuvastatin, increased basal and stimulated expression of the PAI-1 promoter 3-fold. A statin-responsive, nuclear hormone response element was previously identified in the PAI-1 promoter, but it was incompletely characterized. We characterized this direct repeat (DR) of AGGTCA with a 3-nucleotide spacer at -269/-255 using deletion and …

Current State Of The Art Of Regional Hyperthermia Treatment Planning: A Review., H P Kok, P Wust, Paul R. Stauffer, F Bardati, G C Van Rhoon, J Crezee

Department of Radiation Oncology Faculty Papers

Locoregional hyperthermia, i.e. increasing the tumor temperature to 40-45 °C using an external heating device, is a very effective radio and chemosensitizer, which significantly improves clinical outcome. There is a clear thermal dose-effect relation, but the pursued optimal thermal dose of 43 °C for 1 h can often not be realized due to treatment limiting hot spots in normal tissue. Modern heating devices have a large number of independent antennas, which provides flexible power steering to optimize tumor heating and minimize hot spots, but manual selection of optimal settings is difficult. Treatment planning is a very valuable tool to improve …

Thromboembolism After Intramedullary Nailing For Metastatic Bone Lesions., Brandon Shallop, Alexandria Starks, Simon Greenbaum, David S Geller, Alan Lee, John Ready, Geno J Merli, Mitchell Maltenfort, Phd, John A Abraham

Rothman Institute Papers

BACKGROUND: The risk of venous thromboembolism (VTE) in patients undergoing intramedullary nailing for skeletal metastatic disease is currently undefined. The purpose of our study was to determine the risk of thromboembolic events, to define the risk factors for VTE, and to define the rate of wound complications in this population.

METHODS: A retrospective review of surgical databases at three National Cancer Institute (NCI)-designated cancer centers identified 287 patients with a total of 336 impending or pathologic long-bone fractures that were stabilized with intramedullary nailing between February 2001 and April 2013. Statistical analysis was performed utilizing multivariable logistic regression and Fisher …

Conservation Of Inner Nuclear Membrane Targeting Sequences In Mammalian Pom121 And Yeast Heh2 Membrane Proteins., Annemarie Kralt, Noorjahan B Jagalur, Vincent Van Den Boom, Ravi K Lokareddy, Anton Steen, Gino Cingolani, Maarten Fornerod, Liesbeth M Veenhoff

Department of Biochemistry and Molecular Biology Faculty Papers

Endoplasmic reticulum-synthesized membrane proteins traffic through the nuclear pore complex (NPC) en route to the inner nuclear membrane (INM). Although many membrane proteins pass the NPC by simple diffusion, two yeast proteins, ScSrc1/ScHeh1 and ScHeh2, are actively imported. In these proteins, a nuclear localization signal (NLS) and an intrinsically disordered linker encode the sorting signal for recruiting the transport factors for FG-Nup and RanGTP-dependent transport through the NPC. Here we address whether a similar import mechanism applies in metazoans. We show that the (putative) NLSs of metazoan HsSun2, MmLem2, HsLBR, and HsLap2β are not sufficient to drive nuclear accumulation of …

High Throughput Sequencing Identifies Micrornas Mediating Α-Synuclein Toxicity By Targeting Neuroactive-Ligand Receptor Interaction Pathway In Early Stage Of Drosophila Parkinson's Disease Model., Yan Kong, Xijun Liang, Lin Liu, Dongdong Zhang, Chao Wan, Zhenji Gan, Liudi Yuan, Bing-Hua Jiang

Department of Medicine Faculty Papers

Parkinson's disease (PD) is a prevalent neurodegenerative disorder with pathological features including death of dopaminergic neurons in the substantia nigra and intraneuronal accumulations of Lewy bodies. As the main component of Lewy bodies, α-synuclein is implicated in PD pathogenesis by aggregation into insoluble filaments. However, the detailed mechanisms underlying α-synuclein induced neurotoxicity in PD are still elusive. MicroRNAs are ~20nt small RNA molecules that fine-tune gene expression at posttranscriptional level. A plethora of miRNAs have been found to be dysregulated in the brain and blood cells of PD patients. Nevertheless, the detailed mechanisms and their in vivo functions in PD …

A Prospective Highlight On Exosomal Nanoshuttles And Cancer Immunotherapy And Vaccination., Mohammad Rafi, Yadollah Omidi

Department of Neurology Faculty Papers

INTRODUCTION: Exosomes (EXOs) and ectosomes (ECTOs) are nanoscale membranous extracellular vesicles (EVs) derived from different cells mediating various cellular communications. EXOs are liberated based on the exocytosis of multivesicular bodies, while ECTOs are ubiquitously released from the plasma membranes.

METHODS: Here, in this paper, we go over the extracellular vesicular machineries and concisely highlight their clinical importance in solid tumors and their possible applications in cancer immunotherapy/vaccination.

RESULTS: In various types of cancers, these vesicles play central roles delivering cancer cell messages to the target cells, as a result both of them seem to provide a novel useful means for …

Reforming The Veterans Health Administration-Beyond Palliation Of Symptoms, Brett P. Giroir, Md, Gail R. Wilensky, Phd

College of Nursing Faculty Papers & Presentations

The Veterans Health Administration (VHA) is one of the largest health care delivery systems in the United States, with 9.1 million enrollees, 20,000 physicians, 1600 facilities, 288,000 employees, and a $59 billion budget. In response to highly publicized concerns regarding delayed access to care, preventable deaths in patients awaiting care, and falsification of lists to make waiting times appear shorter, Congress passed and President Barack Obama signed the Veterans Access, Choice, and Accountability Act of 2014. In addition to expanding non-VHA treatment options for veterans, this law requires a comprehensive, independent assessment of 12 areas of VHA care delivery and …

Dissecting Tumor Metabolic Heterogeneity: Telomerase And Large Cell Size Metabolically Define A Sub-Population Of Stem-Like, Mitochondrial-Rich, Cancer Cells., Rebecca Lamb, Bela Ozsvari, Gloria Bonuccelli, Duncan L Smith, Richard Pestell, Ubaldo E. Martinez-Outshoorn, Md, Robert B Clarke, Federica Sotgia, Michael P Lisanti

Kimmel Cancer Center Faculty Papers

Tumor cell metabolic heterogeneity is thought to contribute to tumor recurrence, distant metastasis and chemo-resistance in cancer patients, driving poor clinical outcome. To better understand tumor metabolic heterogeneity, here we used the MCF7 breast cancer line as a model system to metabolically fractionate a cancer cell population. First, MCF7 cells were stably transfected with an hTERT-promoter construct driving GFP expression, as a surrogate marker of telomerase transcriptional activity. To enrich for immortal stem-like cancer cells, MCF7 cells expressing the highest levels of GFP (top 5%) were then isolated by FACS analysis. Notably, hTERT-GFP(+) MCF7 cells were significantly more efficient at …

Chimeric Cells Of Maternal Origin Do Not Appear To Be Pathogenic In The Juvenile Idiopathic Inflammatory Myopathies Or Muscular Dystrophy., Carol M Artlett, Sihem Sassi-Gaha, Ronald C Ramos, Frederick W Miller, Lisa G Rider

Department of Medicine Faculty Papers

INTRODUCTION: Microchimeric cells have been studied for over a decade, with conflicting reports on their presence and role in autoimmune and other inflammatory diseases. To determine whether microchimeric cells were pathogenic or mediating tissue repair in inflammatory myopathies, we phenotyped and quantified microchimeric cells in juvenile idiopathic inflammatory myopathies (JIIM), muscular dystrophy (MD), and noninflammatory control muscle tissues.

METHOD: Fluorescence immunophenotyping for infiltrating cells with sequential fluorescence in situ hybridization was performed on muscle biopsies from ten patients with JIIM, nine with MD and ten controls.

RESULTS: Microchimeric cells were significantly increased in MD muscle (0.079 ± 0.024 microchimeric cells/mm(2) …

Relationships Between Cancer Pattern, Country Income And Geographical Region In Asia., Chirk Jenn Ng, Chin Hai Teo, Nurdiana Abdullah, Wei Phin Tan, Hui Meng Tan

Department of Surgery Faculty Papers

BACKGROUND: Cancer incidence and mortality varies across region, sex and country's economic status. While most studies focused on global trends, this study aimed to describe and analyse cancer incidence and mortality in Asia, focusing on cancer site, sex, region and income status.

METHODS: Age-standardised incidence and mortality rates of cancer were extracted from the GLOBOCAN 2012 database. Cancer mortality to incidence ratios (MIRs) were calculated to represent cancer survival. The data were analysed based on the four regions in Asia and income.

RESULTS: Cancer incidence rate is lower in Asia compared to the West but for MIR, it is the …

The Role Of Perlecan And Endorepellin In The Control Of Tumor Angiogenesis And Endothelial Cell Autophagy., Stephen Douglass, Atul Goyal, Renato V. Iozzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

During tumor growth and angiogenesis there is a dynamic remodeling of tissue architecture often accompanied by the release of extracellular matrix constituents full of biological activity. One of the key constituents of the tumor microenvironment is the large heparan sulfate proteoglycan perlecan. This proteoglycan, strategically located at cell surfaces and within basement membranes, is a well-defined pro-angiogenic molecule when intact. However, when partially processed by proteases released during cancer remodeling and invasion, the C-terminal fragment of perlecan, known as endorepellin, has opposite effects than its parent molecule. Endorepellin is a potent inhibitor of angiogenesis by exerting a dual receptor antagonism …

Risk Factors Of Pulmonary Hypertension In Brazilian Patients With Sickle Cell Anemia., Clarisse Lopes De Castro Lobo, Emilia Matos Do Nascimento, Renato Abelha, Ana Maria Mach Queiroz, Philippe Connes, Gilberto Perez Cardoso, Samir K. Ballas

Cardeza Foundation for Hematologic Research

This study was a prospective cross-sectional cohort study of 125 patients with sickle cell anemia (SS) between the ages of 16 to 60 years. Enrolled patients were followed-up prospectively for 15 months. Demographic, clinical, hematological and routine biochemical data were obtained on all patients. Six-minute walk test and Doppler Echocardiography were performed on all patients. A tricuspid regurgitant jet velocity (TRJV) < 2.5 m/sec was considered normal, 2.5 ≤ TRJV ≤ 3.0 was considered mild-moderate and > 3.0 m/sec, severe. Patients with abnormal TRJV were significantly older and more anemic, had significantly higher lactate dehydrogenase (LDH) levels, reticulocyte count and incidence of death. The logistic multimodal model implemented for the 125 patients indicated that age was …

Erbb3-Erbb2 Complexes As A Therapeutic Target In A Subset Of Wild-Type Braf/Nras Cutaneous Melanomas., Claudia Capparelli, Sheera Rosenbaum, Lisa D. Berman-Booty, Amel Salhi, Nadège Gaborit, Tingting Zhan, Inna Chervoneva, Jason Roszik, Scott E. Woodman, Michael A. Davies, Yulius Y. Setiady, Iman Osman, Yosef Yarden, Andrew E. Aplin

Department of Cancer Biology Faculty Papers

The treatment options remain limited for patients with melanoma who are wild-type for both BRAF and NRAS (WT/WT). We demonstrate that a subgroup of WT/WT melanomas display high basal phosphorylation of ErbB3 that is associated with autocrine production of the ErbB3 ligand neuregulin-1 (NRG1). In WT/WT melanoma cells displaying high levels of phospho-ErbB3, knockdown of NRG1 reduced cell viability and was associated with decreased phosphorylation of ErbB3, its coreceptor ErbB2, and its downstream target, AKT. Similar effects were observed by targeting ErbB3 with either siRNAs or the neutralizing ErbB3 monoclonal antibodies huHER3-8 and NG33. In addition, pertuzumab-mediated inhibition of ErbB2 …

Rac1 P29s Regulates Pd-L1 Expression In Melanoma., Ha Linh Vu, Sheera Rosenbaum, Timothy J. Purwin, Michael A. Davies, Andrew E. Aplin

Department of Cancer Biology Faculty Papers

Whole exome sequencing of cutaneous melanoma has led to the detection of P29 mutations in RAC1 in 5-9% of samples, but the role of RAC1 P29 mutations in melanoma biology remains unclear. Using reverse phase protein array analysis to examine the changes in protein/phospho-protein expression, we identified cyclin B1, PD-L1, Ets-1, and Syk as being selectively upregulated with RAC1 P29S expression and downregulated with RAC1 P29S depletion. Using the melanoma patient samples in TCGA, we found PD-L1 expression to be significantly increased in RAC1 P29S patients compared to RAC1 WT as well as other RAC1 mutants. The finding that PD-L1 …

Expression Of The Il-11 Gene In Metastatic Cells Is Supported By Runx2-Smad And Runx2-Cjun Complexes Induced By Tgfβ1., Xuhui Zhang, Hai Wu, Jason R. Dobson, Gillian Browne, Deli Hong, Jacqueline Akech, Lucia R. Languino, Gary S. Stein, Jane B. Lian

Department of Cancer Biology Faculty Papers

In tumor cells, two factors are abnormally increased that contribute to metastatic bone disease: Runx2, a transcription factor that promotes expression of metastasis related and osteolytic genes; and IL-11, a secreted osteolytic cytokine. Here, we addressed a compelling question: Does Runx2 regulate IL-11 gene expression? We find a positive correlation between Runx2, IL-11 and TGFβ1, a driver of the vicious cycle of metastatic bone disease, in prostate cancer (PC) cell lines representing early (LNCaP) and late (PC3) stage disease. Further, like Runx2 knockdown, IL-11 knockdown significantly reduced expression of several osteolytic factors. Modulation of Runx2 expression results in corresponding changes …

Human Ips Cell-Derived Astrocyte Transplants Preserve Respiratory Function After Spinal Cord Injury., Ke Li, Elham Javed, Daniel Scura, Tamara J. Hala, Suneil Seetharam, Aditi Falnikar, Jean-Philippe Richard, Ashley Chorath, Nicholas J. Maragakis, Megan C. Wright, Angelo C. Lepore

Department of Neuroscience Faculty Papers

Transplantation-based replacement of lost and/or dysfunctional astrocytes is a promising therapy for spinal cord injury (SCI) that has not been extensively explored, despite the integral roles played by astrocytes in the central nervous system (CNS). Induced pluripotent stem (iPS) cells are a clinically-relevant source of pluripotent cells that both avoid ethical issues of embryonic stem cells and allow for homogeneous derivation of mature cell types in large quantities, potentially in an autologous fashion. Despite their promise, the iPS cell field is in its infancy with respect to evaluating in vivo graft integration and therapeutic efficacy in SCI models. Astrocytes express …

Perceived Barriers To Infection Prevention And Control For Nursing Home Certified Nursing Assistants: A Qualitative Study., Jasmine Travers, Carolyn T A Herzig, Monika Pogorzelska-Maziarz, Eileen Carter, Catherine C Cohen, Patricia K Semeraro, Ragnhildur I Bjarnadottir, Patricia W Stone

Healthcare-associated infections, while preventable, result in increased morbidity and mortality in nursing home (NH) residents. Frontline personnel, such as certified nursing assistants (CNAs), are crucial to successful implementation of infection prevention and control (IPC) practices. The purpose of this study was to explore barriers to implementing and maintaining IPC practices for NH CNAs as well as to describe strategies used to overcome these barriers. We conducted a multi-site qualitative study of NH personnel important to infection control. Audio-recorded interviews were transcribed verbatim and transcripts were analyzed using conventional content analysis. Five key themes emerged as perceived barriers to effective IPC …

A Novel Compact Microwave Radiometric Sensor To Noninvasively Track Deep Tissue Thermal Profiles, Paolo F. Maccarini, Ankur Shah, Sharmila Y. Palani, Donald V. Pearce, Madhurima Vardhan, Paul R. Stauffer, Dario B. Rodrigues, Sara Salahi, Tiago R. Oliveira, Doug Reudink, Brent W. Snow

Department of Radiation Oncology Faculty Papers

Drawing from space technology to measure star temperature, we developed a noninvasive sensor to passively track thermal profiles in tissues well below the skin (>5cm). Ultra-low noise amplifiers combined with ultralow-loss switches in the 1- 2GHz band produce a high sensitivity multiband microwave radiometer. Due to the complex multilayer anatomy of human head, multiple sensing bands are needed to reconstruct the temperature of deep brain tissue. This is achieved by using a digitally controlled filter bank. To study its accuracy, the sensor was calibrated and tested in a multilayer phantom model of the human head with differential scalp and …

Type Of Preoperative Aura May Predict Postsurgical Outcome In Patients With Temporal Lobe Epilepsy And Mesial Temporal Sclerosis., Ali Akbar Asadi-Pooya, Maromi Nei, Ashwini Sharan, Michael R. Sperling

Department of Neurology Faculty Papers

PURPOSE: As the initial symptoms of epileptic seizures, many types of auras have significant localizing or lateralizing value. In this study, we hypothesized that the type of aura may predict postsurgical outcome in patients with medically refractory temporal lobe epilepsy (TLE) and mesial temporal sclerosis (MTS).

METHODS: In this retrospective study, all patients with a clinical diagnosis of medically refractory TLE due to unilateral mesial temporal sclerosis who underwent epilepsy surgery at the Jefferson Comprehensive Epilepsy Center were recruited. Patients were prospectively registered in a database from 1986 through 2014. Postsurgical outcome was classified into two groups: seizure freedom or …

Pkcε Is An Essential Mediator Of Prostate Cancer Bone Metastasis., Alvaro Gutierrez-Uzquiza, Cynthia Lopez-Haber University Of Pennsylvania, Danielle L. Jernigan, Alessandro Fatatis, Marcelo G. Kazanietz

Kimmel Cancer Center Papers, Presentations, and Grand Rounds

UNLABELLED: The bone is a preferred site for metastatic homing of prostate cancer cells. Once prostate cancer patients develop skeletal metastases, they eventually succumb to the disease; therefore, it is imperative to identify key molecular drivers of this process. This study examines the involvement of protein kinase C epsilon (PKCε), an oncogenic protein that is abnormally overexpressed in human tumor specimens and cell lines, on prostate cancer cell bone metastasis. PC3-ML cells, a highly invasive prostate cancer PC3 derivative with bone metastatic colonization properties, failed to induce skeletal metastatic foci upon inoculation into nude mice when PKCε expression was silenced …

We Can Do Better: An Argument For Improved Care Of The Opioid Addicted Mother-Infant Dyad, Michele K. Savin, Msn, Nnp-Bc

College of Nursing Faculty Papers & Presentations

As the number of addicted maternal-infant dyads increases, so does the need for nursing to expand its understanding of the addiction process and the evidencebased interventions that best serve mothers and infants. Nursing attitudes toward the opioid-addicted mother and infant dyad are influenced by knowledge deficits and communication difficulties. Care required encompasses medical, legal, social, and economic perspectives. Professionals and society at large have disagreements regarding whether to approach the phenomenon from a punitive or supportive strategy. Facilities to care for the mother-infant dyad with addiction are limited. Increasing knowledge has great potential for active understanding and ability to impact …
