The Role Of Estradiol Metabolism In Urogenital Schistosomiasis-Induced Bladder Cancer, Nuno Vale, Maria Gouveia, Gabriel Rinaldi, Julio Santos, Lucio Lara Santos, Paul J. Brindley, Jose Correia Da Costa

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Urogenital schistosomiasis is a neglected tropical disease that can lead to bladder cancer. How urogenital schistosomiasis induces carcinogenesis remains unclear, although there is evidence that the human blood fluke Schistosoma haematobium, the infectious agent of urogenital schistosomiasis, releases estradiol-like metabolites. These kind of compounds have been implicated in other cancers. Aiming for enhanced understanding of the pathogenesis of the urogenital schistosomiasisinduced bladder cancer, here we review, interpret, and discuss findings of estradiol-like metabolites detected in both the parasite and in the human urine during urogenital schistosomiasis. Moreover, we predict pathways and enzymes that are involved in the production of these …

Esm-1 Sirna Knockdown Decreased Migration And Expression Of Cxcl3 In Prostate Cancer Cells, J Rebollo, Jan Geliebter, N Reyes

NYMC Faculty Publications

Endothelial cell-specific molecule-1 (ESM-1), also known as endocan, is a soluble proteoglycan expressed by the vascular endothelium, which also circulates in the bloodstream. Inflammatory cytokines and proangiogenic growth factors increase its expression, and increased serum levels have been reported in several cancer types and immunocompetent patients with sepsis. The aim of this study was to analyze the expression profile of CXC-chemokines and the effects of ESM-1 gene knockdown in proliferation, migration and CXC-chemokine expression in highly metastatic human prostate PC-3 cells. Expression profiles of CXC-chemokines were analyzed in metastatic PC-3 and non-tumorigenic PWR-1E cells. siRNA-mediated knockdown of ESM-1 was performed …

Metastatic Melanoma To The Bladder: Case Report And Review Of The Literature., Rohit V. Patil, Solomon L Woldu, Elena Lucas, Andrew M Quinn, Franto Francis, Vitaly Margulis

Urology Faculty Publications

A 49-year-old Caucasian woman presented to the dermatology clinic for follow-up of malignant melanoma with a complaint of painless gross hematuria. Two years prior she was diagnosed with malignant melanoma from a skin lesion on her left flank treated with wide excision, negative axillary sentinel lymph node biopsy, and adjuvant radiotherapy. Subsequently, she had no evidence of disease until urologic evaluation of her hematuria revealed two lesions in her bladder and cytopathology demonstrated findings consistent with malignant melanoma. We review literature on melanoma metastatic to the bladder and discuss the potential role of metastasectomy and other treatment strategies in such …

Cold Atmospheric Plasma, A Novel Promising Anti-Cancer Treatment Modality., Dayun Yan, Jonathan H Sherman, Michael Keidar

Neurological Surgery Faculty Publications

Over the past decade, cold atmospheric plasma (CAP), a near room temperature ionized gas has shown its promising application in cancer therapy. Two CAP devices, namely dielectric barrier discharge and plasma jet, show significantly anti-cancer capacity over dozens of cancer cell lines in vitro and several subcutaneous xenograft tumors in vivo. In contrast to conventional anti-cancer approaches and drugs, CAP is a selective anti-cancer treatment modality. Thus far establishing the chemical and molecular mechanism of the anti-cancer capacity of CAP is far from complete. In this review, we provide a comprehensive introduction of the basics of CAP, state of the …

Group Medical Visits To Provide Gynecologic Care For Women Affected By Breast Cancer, Sally R. Greenwald, Sarah Watson, Mindy Goldman, Tami S. Rowen

Journal of Patient-Centered Research and Reviews

Purpose

Women with breast cancer have complex and unique gynecologic needs that are challenging to effectively and comprehensively meet in a traditional gynecology visit format. Group medical visits are an effective and well-received model of care in other disease settings and can provide comprehensive health education as an adjunct to one-on-one evaluation and treatment. There are limited data regarding the use of this type of health care delivery in providing gynecology-focused care to women affected by breast cancer.

Methods

A group medical visit model was created for gynecology providers to see new breast cancer patient consults. From May 2012 to …

Hic1 (Hypermethylated In Cancer 1) Sumoylation Is Dispensable For Dna Repair But Is Essential For The Apoptotic Dna Damage Response (Ddr) To Irreparable Dna Double-Strand Breaks (Dsbs)., Sonia Paget, Marion Dubuissez, Vanessa Dehennaut, Joe Nassour, Brennan T Harmon, Nathalie Spruyt, Ingrid Loison, Corinne Abbadie, Brian R Rood, Dominique Leprince

Surgery Faculty Publications

The tumor suppressor gene HIC1 (Hypermethylated In Cancer 1) encodes a transcriptional repressor mediating the p53-dependent apoptotic response to irreparable DNA double-strand breaks (DSBs) through direct transcriptional repression of SIRT1. HIC1 is also essential for DSB repair as silencing of endogenous HIC1 in BJ-hTERT fibroblasts significantly delays DNA repair in functional Comet assays. HIC1 SUMOylation favours its interaction with MTA1, a component of NuRD complexes. In contrast with irreparable DSBs induced by 16-hours of etoposide treatment, we show that repairable DSBs induced by 1 h etoposide treatment do not increase HIC1 SUMOylation or its interaction with MTA1. Furthermore, HIC1 SUMOylation …

Natural Compounds Targeting Major Cell Signaling Pathways: A Novel Paradigm For Osteosarcoma Therapy., Pablo Angulo, Gaurav Kaushik, Dharmalingam Subramaniam, Prasad Dandawate, Kathleen Neville, Katherine Chastain, Shrikant Anant

Manuscripts, Articles, Book Chapters and Other Papers

Osteosarcoma is the most common primary bone cancer affecting children and adolescents worldwide. Despite an incidence of three cases per million annually, it accounts for an inordinate amount of morbidity and mortality. While the use of chemotherapy (cisplatin, doxorubicin, and methotrexate) in the last century initially resulted in marginal improvement in survival over surgery alone, survival has not improved further in the past four decades. Patients with metastatic osteosarcoma have an especially poor prognosis, with only 30% overall survival. Hence, there is a substantial need for new therapies. The inability to control the metastatic progression of this localized cancer stems …

Metabolic Reprogramming Of Triple-Negative Breast Cancer: The Role Of Mirnas, Amal Qattan

Biochemistry and Molecular Medicine Faculty Publications

MicroRNAs (miRNAs) are well known to influence the expression of the genes that regulate critical cellular functions. Various reports have suggested that they play critical roles in breast cancer metabolism through the regulation of various metabolic pathways, including the metabolism of glucose, lipids, glycolysis and the mitochondrial tricarboxylic acid cycle (TCA). miRNAs regulate the metabolic process by targeting key molecules (enzymes, kinases transporters) or by modifying the expression of key transcription molecules. In addition, miRNAs can indirectly regulate mRNA translation by targeting chromatin-remodeling enzymes. Furthermore, miRNAs influence the expression of both oncogenes and tumor suppressors and have a major impact …

Purpose: RNA and DNA sequencing data are traditionally used to discern intrinsic cellular pathways in cancer pathogenesis, their utility for investigating the tumor microenvironment (TME) has not been fully explored. This study explores the use of sequencing data to investigate immunity within the TME.

Experimental design: Here, we use immune cell fraction estimation analysis to determine the immune profiles in the microenvironment of neuroblastoma (NB) based on RNA-seq data in the TARGET database. The correlation between immune cell transcripts and prognosis in pediatric NB is also investigated.

Results: In silico analysis revealed a strong inverse correlation between MYCNamplification and …

Primary Pulmonary Malt Lymphoma Presenting As Non-Resolving Pneumonia, Asma Iftikhar, Albert Magh, Muhammed Azaz Cheema, Sarah Thappa, Sonu Sahni, Stephen Karbowitz

Touro College of Osteopathic Medicine (New York) Publications and Research

Primary lung lymphoma (PLL) is a rare unilateral or bilateral lung disorder that is challenging to diagnose solely based on clinical and radiological presentation. PLL may be misdiagnosed as pneumonia or a lung tumor due to non-specific findings. PLL is most frequently a mucosa-associated lymphoid tissue (MALT) lymphoma, a type of extranodal low-grade B-cell lymphoma most commonly discovered in the gastrointestinal tract. PLL should be considered in the differential diagnosis of non-resolving pneumonias. Herein we present a case of an 84-year-old patient discovered to have a primary pulmonary MALT lymphoma presenting as a non-resolving pneumonia causing a clinical challenge.

Characterization Of Malt1 Inhibitors And Their Effect On Leukemic Cell Growth Properties, Christina Snyder

Graduate School of Biomedical Sciences Theses and Dissertations

Leukemia is the most common childhood cancer, with a combined 40,000 predicted new cases in the United States in 2016 [8]. The two most common subtypes are acute myeloid leukemia (AML) and chronic lymphocytic leukemia (CLL) [9-11]. The commercially available inhibitor of Bruton’s tyrosine kinase (BTK) has shown promising results in clinical trials for CLL because of the importance of BCR signaling in CLL [12-15]. Recent studies suggest that the outgrowth of BTK inhibitor resistant clonal cells in some CLL patients results in a treatment-refractory phenotype [16-18]. MALT1, a protein involved in BCR activation of the NF-κB pathway that functions …

Development Of Cellular Assays To Monitor Enzymatic And Biological Activity Of Cd73: A Key Modulator Of Anti-Tumor Immune Response, Alexandra Fanuka

Graduate School of Biomedical Sciences Theses and Dissertations

Ecto-5’-nucleotidase, known as CD73, is an extracellular enzyme that converts adenosine monophosphate (AMP) to adenosine and has recently been identified as a potential drug target for cancer immunotherapy. Its immunosuppressive effects, mediated by the activity of adenosine, are associated with higher rates of tumor invasion and metastasis, as well as poorer prognoses overall in many cancer types. CD73 is often co-expressed with ectonucleoside triphosphate diphosphohydrolase-1 (CD39), which catalyzes the conversion of adenosine triphosphate (ATP) to adenosine diphosphate (ADP), and ADP to AMP on the surface of tumor cells. Dual expression further propagates immunosuppressive effects of adenosine in the tumor microenvironment. …

Medicine Faculty Publications

Clinical Practice Points. Plasmablastic lymphoma (PBL) is a rare and highly aggressive variant of diffuse large B cell lymphoma with median survival of advanced stage patients varying between 6 and 15 months in previous reports. We report here a human immunodeficiency virus-infected patient surviving over 12 years following treatment for advanced PBL with EPOCH chemotherapy and intrathecal therapy. This case highlights the potential for improved survival in PBL with intensive chemotherapy. Further, literature review suggests promising prospects utilizing novel targeted therapies to increase the rate of prolonged responses.

Testing Mice At Risk Of Pancreatic Cancer For Altered Protein Pathways Found In Diabetes, Henley Cheung

Honors Undergraduate Theses

Pancreatic cancer is nearly asymptomatic, which can result in extensive grow and even metastasis to other organs before detection. When diagnosed at a late stage, the survival rate is 3%. Early detection is therefore the key to treating pancreatic cancer. Diabetes was identified as a risk factor for the development of pancreatic cancer, but the mechanism remains unknown. In this project, the objective was to delineate a link between diabetes and pancreatic cancer by examining their shared protein signaling pathways. In a previous study, hyper-activation of AKT1 resulted in a pre-diabetic phenotype and also increased upregulation of downstream phosphorylated mTOR …

Reducing The Rate Of Late Stage Breast Cancer Through Effective Health Communication: An Opinion Piece, Rachele Hendricks-Sturrup

Internet Journal of Allied Health Sciences and Practice

Purpose: Health and illness are traditionally characterized and treated differently across various ethnic groups, which encourages American health systems serving these diverse populations to explore culturally competent and safe ways to effectively reduce illness within such populations. Certain ethnic groups of women in the United States (US) bear greater risk of late stage breast cancer because of various circumstances, which include but are not limited to a lack of insurance or underinsurance and discomfort with and/or resentment toward the US healthcare system. The dominant culture and the social aspects of the modern American health system often and most favorably serve …

Journal Articles: Eppley Institute

Adenocarcinoma (ADC) and squamous cell carcinoma (SqCC) are the two predominant subtypes of non-small cell lung cancer (NSCLC) and are distinct in their histological, molecular and clinical presentation. However, metabolic signatures specific to individual NSCLC subtypes remain unknown. Here, we perform an integrative analysis of human NSCLC tumour samples, patient-derived xenografts, murine model of NSCLC, NSCLC cell lines and The Cancer Genome Atlas (TCGA) and reveal a markedly elevated expression of the GLUT1 glucose transporter in lung SqCC, which augments glucose uptake and glycolytic flux. We show that a critical reliance on glycolysis renders lung SqCC vulnerable to glycolytic inhibition, …
