Predictors Of High-Sensitivity Cardiac Troponin T Elevation In Patients With Acute Paroxysmal Supraventricular Tachycardia And Ischemic Heart Disease, Mehdi Sayadnik, Akbar Shafiee, Yaser Jenab, Arash Jalali, Saeed Sadeghian

The Texas Heart Institute Journal

We studied the predictors and patterns of high-sensitivity cardiac troponin T (hs-cTnT) elevation in patients with paroxysmal supraventricular tachycardia (PSVT) in the presence and absence of ischemic heart disease.

During calendar year 2013, we enrolled 70 of 72 consecutive adult patients with PSVT who presented at our center within 4 hours after the onset of tachycardia. On the basis of increased hs-cTnT at either of 2 initial measurements, we divided patients into groups (hs-cTnT–positive and hs-cTnT–negative), to study the predictors of enzyme elevation. We then divided the hs-cTnT–positive patients into 2 groups—those with and those without ischemic heart disease—and compared …

Inhibition Of Apoptosis Signal-Regulating Kinase 1 Alters The Wound Epidermis And Enhances Auricular Cartilage Regeneration., Qian-Shi Zhang, Deepa S. Kurpad, My G. Mahoney, Marla J. Steinbeck, Theresa A. Freeman

Department of Orthopaedic Surgery Faculty Papers

Why regeneration does not occur in mammals remains elusive. In lower vertebrates, epimorphic regeneration of the limb is directed by the wound epidermis, which controls blastema formation to promote regrowth of the appendage. Herein, we report that knockout (KO) or inhibition of Apoptosis Signal-regulated Kinase-1 (ASK1), also known as mitogen-activated protein kinase kinase kinase 5 (MAP3K5), after full thickness ear punch in mice prolongs keratinocyte activation within the wound epidermis and promotes regeneration of auricular cartilage. Histological analysis showed the ASK1 KO ears displayed enhanced protein markers associated with blastema formation, hole closure and regeneration of auricular cartilage. At seven …

The majority of pancreatic ductal adenocarcinomas (PDAC) rely on the mRNA stability factor HuR (ELAV-L1) to drive cancer growth and progression. Here, we show that CRISPR-Cas9–mediated silencing of the HuR locus increases the relative sensitivity of PDAC cells to PARP inhibitors (PARPi). PDAC cells treated with PARPi stimulated translocation of HuR from the nucleus to the cytoplasm, specifically promoting stabilization of a new target, poly (ADP-ribose) glycohydrolase (PARG) mRNA, by binding a unique sequence embedded in its 3⁰ untranslated region. HuR-dependent upregulation of PARG expression facilitated DNA repair via hydrolysis of polyADP-ribose on related repair proteins. Accordingly, strategies to …

Autoantibodies As Diagnostic Biomarkers For The Detection And Subtyping Of Multiple Sclerosis, Cassandra Demarshall, Eric Goldwaser, Abhirup Sarkar, George Godsey, Nimish Acharya, Umashanger Thayasivam, Benjamin Belinka, Robert Nagele

Rowan-Virtua School of Osteopathic Medicine Departmental Research

The goal of this preliminary proof-of-concept study was to use human protein microarrays to identify blood-based autoantibody biomarkers capable of diagnosing multiple sclerosis (MS). Using sera from 112 subjects, including 51 MS subjects, autoantibody biomarkers effectively differentiated MS subjects from age- and gender-matched normal and breast cancer controls with 95.0% and 100% overall accuracy, but not from subjects with Parkinson's disease. Autoantibody biomarkers were also useful in distinguishing subjects with the relapsing-remitting form of MS from those with the secondary progressive subtype. These results demonstrate that autoantibodies can be used as noninvasive blood-based biomarkers for the detection and subtyping of …

Hsp27 And Chemotherapy-Induced Autophagy As Biomarkers In Osteosarcoma, John Andrew Livingston

Dissertations and Theses (Open Access)

Survival for patients with osteosarcoma has not improved for > 30 years. Despite aggressive multi-agent chemotherapy combined with surgical resection, a significant fraction of patients with localized disease relapse after optimal treatment. We evaluated the occurrence of cytoplasmic LC3B (light chain 3B)-positive puncta (a marker of autophagy) and presence of HSP27 (heat shock protein 27) in cancer cells within pre-treatment biopsy, post-treatment surgical resection, and metastatic osteosarcoma specimens by immunohistochemistry in 260 patients. LCB3+ puncta expression was seen in 34% of pre-treatment. 50% of resection, and 67% of metastasis samples. Sixty-six percent of all specimens were scored positive for HSP27 (85% …

Brain Biomarkers And Pre-Injury Cognition Are Associated With Long-Term Cognitive Outcome In Children With Traumatic Brain Injury, Amy A Wilkinson, Maureen Dennis, Nevena Simic, Margot J Taylor, Benjamin R Morgan, Helena Frndova, Karen Choong, Craig Campbell, Douglas Fraser, Vicki Anderson, Anne-Marie Guerguerian, Russell Schachar, Jamie Hutchison

Paediatrics Publications

BACKGROUND: Children with traumatic brain injury (TBI) are frequently at risk of long-term impairments of attention and executive functioning but these problems are difficult to predict. Although deficits have been reported to vary with injury severity, age at injury and sex, prognostication of outcome remains imperfect at a patient-specific level. The objective of this proof of principle study was to evaluate a variety of patient variables, along with six brain-specific and inflammatory serum protein biomarkers, as predictors of long-term cognitive outcome following paediatric TBI.

METHOD: Outcome was assessed in 23 patients via parent-rated questionnaires related to attention deficit hyperactivity disorder …

Ccr4 Is A Determinant Of Melanoma Brain Metastasis., Anat Klein, Orit Sagi-Assif, Tsipi Meshel, Alona Telerman, Sivan Izraely, Shlomit Ben-Menachem, Jagadeesh Bayry, Diego M Marzese, Shuichi Ohe, Dave S B Hoon, Neta Erez, Isaac P Witz

Articles, Abstracts, and Reports

We previously identified the chemokine receptor CCR4 as part of the molecular signature of melanoma brain metastasis. The aim of this study was to determine the functional significance of CCR4 in melanoma brain metastasis. We show that CCR4 is more highly expressed by brain metastasizing melanoma cells than by local cutaneous cells from the same melanoma. Moreover, we found that the expression of CCR4 is significantly higher in paired clinical specimens of melanoma metastases than in samples of primary tumors from the same patients. Notably, the expression of the CCR4 ligands, Ccl22 and Ccl17 is upregulated at the earliest stages …

Saha Cardiovascular Research Center Faculty Publications

Introduction

Preeclampsia (PE) is a gestational disorder, manifested in the second half of pregnancy by maternal hypertension, proteinuria and generalized edema. PE is a major cause of maternal and fetal morbidity and mortality, accounting for nearly 40% of all premature births worldwide. Bioactive sphingolipids are emerging as key molecules involved in etiopathogenesis of PE, characterized by maternal angiogenic imbalance and symptoms of metabolic syndrome. The aim of this study was to compare the cross-gestational profile of circulating bioactive sphingolipids in maternal plasma from preeclamptic (PE) versus normotensive control (CTL) subjects with the goal of identifying sphingolipids as candidate first trimester …

Differentiated State Of Initiating Tumor Cells Is Key To Distinctive Immune Responses Seen In H-Ras, Michael A Podolsky, Jacob T Bailey, Andrew J Gunderson, Carrie J Oakes, Kyle Breech, Adam B Glick

Articles, Abstracts, and Reports

Heterogeneity in tumor immune responses is a poorly understood yet critical parameter for successful immunotherapy. In two doxycycline-inducible models where oncogenic H-RasG12V is targeted either to the epidermal basal/stem cell layer with a Keratin14-rtTA transgene (K14Ras), or committed progenitor/suprabasal cells with an Involucrin-tTA transgene (InvRas), we observed strikingly distinct tumor immune responses. On threshold doxycycline levels yielding similar Ras expression, tumor latency, and numbers, tumors from K14Ras mice had an immunosuppressed microenvironment, whereas InvRas tumors had a proinflammatory microenvironment. On a Rag1-/- background, InvRas mice developed fewer and smaller tumors that regressed over time, whereas K14Ras mice developed more …

Publications and Research

Cancer patients often experience weight loss caused by protein calorie malnutrition (PCM) during the course of the disease or treatment. PCM is expressed as severe if the patient has two or more of the following characteristics: obvious significant muscle wasting, loss of subcutaneous fat; nutritional intake of <50% of recommended intake for 2 weeks or more; bedridden or otherwise significantly reduced functional capacity; weight loss of >2% in 1 week, 5% in 1 month, or 7.5% in 3 months. Cancer anorexiacachexia syndrome (CACS) is a multifactorial condition of advanced PCM associated with underlying illness (in this case cancer) and is characterized by loss of muscle with or without loss of fat mass. Cachexia is defined as weight loss of …

Cancer Antigen 125 Is Associated With Length Of Stay In Patients With Acute Heart Failure, Hakki Kaya, Recep Kurt, Osman Beton, Ali Zorlu, Hasan Yucel, Hakan Gunes, Didem Oguz, Mehmet Birhan Yilmaz

The Texas Heart Institute Journal

Length of stay is the primary driver of heart-failure hospitalization costs. Because cancer antigen 125 has been associated with poor morbidity and mortality rates in heart failure, we investigated the relationship between admission cancer antigen 125 levels and lengths of stay in heart-failure patients. A total of 267 consecutive patients (184 men, 83 women) with acute decompensated heart failure were evaluated prospectively. The median length of stay was 4 days, and the patients were classified into 2 groups: those with lengths of stay ≤4 days and those with lengths of stay >4 days. Patients with longer lengths of stay had …

Sin

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is currently the third leading cause of death and there is a huge unmet clinical need to identify disease biomarkers in peripheral blood. Compared to gene level differential expression approaches to identify gene signatures, network analyses provide a biologically intuitive approach which leverages the co-expression patterns in the transcriptome to identify modules of co-expressed genes.

METHODS: A weighted gene co-expression network analysis (WGCNA) was applied to peripheral blood transcriptome from 238 COPD subjects to discover co-expressed gene modules. We then determined the relationship between these modules and forced expiratory volume in 1 s (FEV …

Barnstable Brown Diabetes Center Faculty Publications

Skeletal co-morbidities in type 1 diabetes include an increased risk for fracture and delayed fracture healing, which are intertwined with disease duration and the presence of other diabetic complications. As such, chronic hyperglycemia is undoubtedly a major contributor to these outcomes, despite standard insulin-replacement therapy. Therefore, using the streptozotocin (STZ)-induced model of hypoinsulinemic hyperglycemia in DBA/2J male mice, we compared the effects of two glucose lowering therapies on the fracture resistance of bone and markers of bone turnover. Twelve week-old diabetic (DM) mice were treated for 9 weeks with: 1) oral canagliflozin (CANA, dose range ~10-16 mg/kg/day), an inhibitor of …

Department of Medical Oncology Faculty Papers

The availability of blood-based diagnostic testing using a non-invasive technique holds promise for real-time monitoring of disease progression and treatment selection. Circulating tumor cells (CTCs) have been used as a prognostic biomarker for the metastatic breast cancer (MBC). The molecular characterization of CTCs is fundamental to the phenotypic identification of malignant cells and description of the relevant genetic alterations that may change according to disease progression and therapy resistance. However, the molecular characterization of CTCs remains a challenge because of the rarity and heterogeneity of CTCs and technological difficulties in the enrichment, isolation and molecular characterization of CTCs. In this …
