Plasmapheresis And Hiv-Associated Thrombotic Microangiopathy: An Institutional Review, Megan Fisher, Ms2, Nancy Edger Hall, Rn, Mba, Jennifer Webb, Md, Julie Karp, Md

Department of Pathology Honors Program Student Research Symposium

Thrombotic thrombocytopenic purpura (TTP) is a systemic disorder that classically results from a deficiency in the von Willebrand factor-cleaving enzyme, ADAMTS13. The human immunodeficiency virus (HIV) is a secondary cause of TTP. It has been recognized that some patients with HIV-associated TTP do not have a deficiency in ADAMTS13 activity. The role of plasmapheresis (PLEX) in these patients is unclear. This study reviewed 8 cases of HIV-associated TTP at Thomas Jefferson University Hospital. All patients responded to treatment; however, we were unable to make any conclusions regarding the use of PLEX in patients with normal ADAMTS13 activity. HAART initiation is …

Her-2 Heterogeneity In Breast Cancer: A Case Study, Kinnari Patel, Theodore Parsons

Department of Pathology Honors Program Student Research Symposium

CASE

The patient is a 75 year-old female with a history of stage 1 invasive ductal carcinoma of the left breast measuring 1.2 cm. Core biopsy of the mass demonstrated Nottingham grade 3 invasive ductal carcinoma; ER negative, PR negative, HER-2 negative (1+). The patient underwent mastectomy in April 2013. Mastectomy confirmed Nottingham grade 3 invasive ductal carcinoma pT1c/pN0/pMX with peritumoral lymphovascular invasion and invasive tumor less than 1 mm from the superoanterior margin. Due to comorbidities the patient was not considered a candidate for adjuvant chemotherapy.

In January 2014 the patient presented with a mastectomy site recurrence. Needle core …

T-CELL RECEPTOR, NORMALLY

T-cell receptors reside on the surface of T-cells, and recognize a specific antigen presented by an MHC molecule

Next, the T-cells become either CD4 or CD8 cells

Co-stimulation is a key step in activating the T-cell; B7 proteins on the surface of antigen-presenting cells interact with CD28/CTLA-4 receptors on the T-cell.

Haploidentical Hematopoietic Stem Cell Transplantation: Rationale, Development, And Jefferson’S Method, Susan Mcilvaine, Dolores Grosso, Rn, Crnp, Dnp, Beth Colombe

Department of Pathology Honors Program Student Research Symposium

INTRODUCTION

There are many indications for hematopoietic stem cell transplantation. In addition to hematologic malignancies, transplants are performed in certain non-hematologic malignancies, for marrow disorders such as Sickle Cell Anemia, and for various inherited disorders such as SCID. Traditionally, transplants have been performed between donors and recipients that are a complete HLA match (typically matched siblings). That is, patients have identical HLA alleles on both copies of chromosome 6. HLA alleles code for major histocompatibility complex molecules, which are the proteins that cause transplant rejection when a mismatch between donor and recipient is present. Thus, matched transplants have been historically …

Small Cell Carcinoma Of The Bladder: A Rare Entity, Andrew H. Matthews, Ruth Birbe, Md

Department of Pathology Honors Program Student Research Symposium

BACKGROUND

Primary small cell carcinoma of the urinary bladder is a rare tumor, accounting for less than 1% of the annual 70,000 cases of urinary bladder cancer.¹ Accordingly, little data is available beyond case series to guide diagnosis or treatment. Overall prognosis remains poor with five year survival often markedly below 50%. Current staging and treatment remains largely based on extrapolation from small cell carcinoma of the lung. We review two recent cases of bladder small cell carcinoma with a focus on comparing and contrasting with lung small carcinoma.

Giant Cell Tumor Of Soft Tissue: A Case Study, Rachel Schneider, Brian J. O'Hara

Department of Pathology Honors Program Student Research Symposium

BACKGROUND

Giant cell tumors of soft tissue are relatively uncommon tumors. They are considered to be the soft tissue counterpart to giant cell tumors of bone. Both tumors consist of multi-nucleated giant cells evenly distributed throughout a background of epithelioid mononuclear cells, and are usually benign, but can be locally invasive. Giant cell tumors of soft tissue typically occur in patients over age 40, and show no gender or racial predilection. They present as firm, well demarcated masses, which are not connected to the underlying muscle, tendon, or bone. Giant cell tumors of soft tissue are generally small, and tend …

Small Cell Carcinoma Of The Breast, Victor Carlson, Paolo Cotzia, Md, Juan P. Palazzo, Md

Department of Pathology Honors Program Student Research Symposium

INTRODUCTION

Small cell carcinoma of the breast (SCCB) is a rare, highly aggressive neoplasm first reported in 1983. With striking histologic similarity to small cell carcinoma of the lung, it is comprised of small cells with relatively large, hyperchromatic nuclei and scanty cytoplasm. While capable of hormone secretion, this is a rare occurrence in this variant of small cell carcinoma. Patients typically present with a suspicious breast mass confirmed on imaging, with variable lymph node invasion.

Motor Axon Synapses On Renshaw Cells Contain Higher Levels Of Aspartate Than Glutamate, Dannette Shanon Richards, Ronald W. Griffith, Shannon H. Romer, Francisco J. Alvarez

Neuroscience, Cell Biology & Physiology Faculty Publications

Motoneuron synapses on spinal cord interneurons known as Renshaw cells activate nicotinic, AMPA and NMDA receptors consistent with co-release of acetylcholine and excitatory amino acids (EAA). However, whether these synapses express vesicular glutamate transporters (VGLUTs) capable of accumulating glutamate into synaptic vesicles is controversial. An alternative possibility is that these synapses release other EAAs, like aspartate, not dependent on VGLUTs. To clarify the exact EAA concentrated at motor axon synapses we performed a quantitative postembedding colloidal gold immunoelectron analysis for aspartate and glutamate on motor axon synapses (identified by immunoreactivity to the vesicular acetylcholine transporter; VAChT) contacting calbindin-immunoreactive (-IR) Renshaw …

The Mi-2 Homolog Mit1 Actively Positions Nucleosomes Within Heterochromatin To Suppress Transcription, Kevin M. Creamer

Theses and Dissertations (ETD)

Eukaryotic DNA is packaged into the nucleus in complex with proteins that regulate access and utilization of the genetic material. These DNA and protein complexes form a dynamic structure known as chromatin. Nucleosomes are the repeating unit of chromatin, and consist of DNA wrapped around an octamer of histone proteins. Nucleosomes can then be modified and spatially arranged to facilitate processes such as transcription, DNA replication, and repair. A special transcriptionally repressive chromatin structure assembles onto gene-poor, repetitive regions of the genome known as constitutive heterochromatin. Mit1 is the putative chromatin remodeling subunit of the fission yeast Snf2/HDAC repressor complex …

Molecular Characterization Of Glioblastoma Cancer Stem Cells, Jo Meagan Garner

Theses and Dissertations (ETD)

Malignant gliomas are locally aggressive, highly vascular tumors that have an overall survival time less than 14 months, and current therapies provide little improvement in the disease course and outcome. While glioblastoma multiforme (GBM) patients present uniform histological phenotypes, the molecular determinants of the disease vary considerably between individual cases resulting in complicated prognosis. The heterogeneity, aggressiveness and rapid tumor relapse of GBM is believed to be sustained by cancer stem-like cell populations that are able to initiate and maintain tumors. Although CSCs represent only a small fraction of cells within a tumor, their high tumor-initiating capacity and therapeutic resistance …

Differential Regulation Of Iress In The Aurora A Mrna By Bfgf Through The Mtor Complex To Rc2 Modulates Aurora A Kinase Expression, Roy L. Voice Iii

Dissertations and Theses (Open Access)

Identifying the mechanisms that contribute to tumorigenesis is a major area of focus in our fight against cancer. Epithelial malignant tumors, such as breast, colon, ovarian and pancreatic cancers have been shown to overexpress proteins that control cell mitosis, growth, and proliferation. One of those proteins is the Aurora A kinase. Aurora A kinase is a member of a small family of kinases that contribute to mitotic events such as centrosome duplication, separation, and maturation. Aurora A overexpression leads to genomic instability, which can contribute to tumorigenesis, on the other hand, inhibiting Aurora A expression leads to apoptosis, making it …

Novel Therapeutic Approaches For Ischemic Heart And Brain Injury: Modulation Of Toll-Like Receptor-Mediated Signaling Pathways And Pi3k/Akt Signaling, Chen Lu

Electronic Theses and Dissertations

Innate immune and inflammatory responses contribute to myocardial and cerebral ischemia/reperfusion (I/R) injury. Toll-like receptors (TLRs) play a critical role in the induction of innate immune and inflammatory responses via activation of nuclear factor kappa B (NF-κB). We have shown that activation of NF-κB contributes to myocardial and cerebral I/R injury. Indeed, inhibition of TLR4-mediated NF-κB activation significantly decreased myocardial and cerebral I/R injury via activation of PI3K/Akt signaling. PI3K/Akt signaling is an important pathway in regulating cellular survival and inflammatory responses. Therefore, an important question is how to differentially modulate PI3K/Akt signaling and TLR/NF-κB-mediated signaling pathway during I/R injury? …

Photobiostimulation In C. Elegans As A Model For Low Level Light Therapy, Michael J. Spoto, Daryl D. Hurd

Science Scholars

Low-Level Laser Therapy (LLLT) is a developing therapeutic technique that has been gaining recognition in the scientific community in recent years. Previous experiments performed in LLLT research projects have been primarily mammalian and cell culture based. These experiments have produced results showing accelerated tissue repair. In this experiment, we introduce a new model, Caenorhabitidis elegans, a free-living soil nematode, to be used in LLLT research by testing the effects of exposure of the organism to various wavelengths and intensities of light commonly used in LLLT. C. elegans was shown to respond to photobiostimulation when exposed to specific wavelengths of …

Background

Primary CNS lymphoma (PCNSL) is a rare type of diffuse large B-cell lymphoma (DLBCL) arising from and usually confined to CNS. Understating of the pathogenesis and prognostic markers is a challenge due to rarity of this neoplasm and paucity of the material available to study. Recent studies have shown that dual expression of MYC and BCL2 in DLBCL contributes to inferior overall survival. The prognostic value of MYC and BCL2 in PCNSL is not well studied.

Mir-17/20 Sensitization Of Breast Cancer Cells To Chemotherapy-Induced Apoptosis Requires Akt1., Zuoren Yu, Zengguang Xu, Gabriele Disante, Jennifer Wright, Min Wang, Yuan Li, Qian Zhao, Tao Ren, Xiaoming Ju, Ellen Gutman, Guangxue Wang, Sankar Addya, Tieyan Li, Zhendong Xiang, Chenguang Wang, Xiongfei Yang, Xiaolai Yang, Richard Pestell

Department of Cancer Biology Faculty Papers

The serine threonine kinase Akt1 has been implicated in the control of cellular metabolism, survival and growth. Herein, disruption of the ubiquitously expressed member of the Akt family of genes, Akt1, in the mouse, demonstrates a requirement for Akt1 in miRNA-mediated cellular apoptosis. The miR-17/20 cluster is known to inhibit breast cancer cellular proliferation through G1/S cell cycle arrest via binding to the cyclin D1 3'UTR. Here we show that miR-17/20 overexpression sensitizes cells to apoptosis induced by either Doxorubicin or UV irradiation in MCF-7 cells via Akt1. miR-17/20 mediates apoptosis via increased p53 expression which promotes Akt degradation. Akt1-/- …

Adult Spinal Motoneurones Are Not Hyperexcitable In A Mouse Model Of Inherited Amyotrophic Lateral Sclerosis, Nicolas Delestrée, Marin Manuel, Caroline Iglesias, Sherif M. Elbasiouny, C. J. Heckman, Daniel Zytnicki

Neuroscience, Cell Biology & Physiology Faculty Publications

In amyotrophic lateral sclerosis (ALS), an adult onset disease in which there is progressive degeneration of motoneurones, it has been suggested that an intrinsic hyperexcitability of motoneurones (i.e. an increase in their firing rates), contributes to excitotoxicity and to disease onset. Here we show that there is no such intrinsic hyperexcitability in spinal motoneurones. Our studies were carried out in an adult mouse model of ALS with a mutated form of superoxide dismutase 1 around the time of the first muscle fibre denervations. We showed that the recruitment current, the voltage threshold for spiking and the frequency–intensity gain in the …

Inputs Drive Cell Phenotype Variability., James Park, Anthony Brureau, Kate Kernan, Alexandria Starks, Sonali Gulati, Babatunde Ogunnaike, James S. Schwaber, Rajanikanth Vadigepalli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

What is the significance of the extensive variability observed in individual members of a single-cell phenotype? This question is particularly relevant to the highly differentiated organization of the brain. In this study, for the first time, we analyze the in vivo variability within a neuronal phenotype in terms of input type. We developed a large-scale gene-expression data set from several hundred single brainstem neurons selected on the basis of their specific synaptic input types. The results show a surprising organizational structure in which neuronal variability aligned with input type along a continuum of sub-phenotypes and corresponding gene regulatory modules. Correlations …

Carp-1 Functional Mimetics Are A Novel Class Of Small Molecule Inhibitors Of Malignant Pleural Mesothelioma Cells, Shazia Jamal, Vino T. Cheriyan, Magesh Muthu, Sara Munie, Edi Levi, Abdelkader E. Ashour, Harvey I. Pass, Anil Wali, Mandip Singh, Arun K. Rishi

Oncology Faculty Publications

Malignant pleural mesothelioma (MPM) is an asbestos-related thoracic malignancy that is characterized by late metastases, and resistance to therapeutic modalities. The toxic side-effects of MPM therapies often limit their clinical effectiveness, thus necessitating development of new agents to effectively treat and manage this disease in clinic. CARP-1 functional mimetics (CFMs) are a novel class of compounds that inhibit growth of diverse cancer cell types. Here we investigated MPM cell growth suppression by the CFMs and the molecular mechanisms involved. CFM-1, -4, and -5 inhibited MPM cell growth, in vitro, in part by stimulating apoptosis. Apoptosis by CFM-4 involved activation of …

Depletion Of Pre-Mrna Splicing Factor Cdc5l Inhibits Mitotic Progression And Triggers Mitotic Catastrophe., R Mu, Y-B Wang, M Wu, Y Yang, W Song, T Li, W-N Zhang, B Tan, A-L Li, N Wang, Q Xia, W-L Gong, Chenguang Wang, T Zhou, N Guo, Z-H Sang, H-Y Li

Department of Cancer Biology Faculty Papers

Disturbing mitotic progression via targeted anti-mitotic therapy is an attractive strategy for cancer treatment. Therefore, the exploration and elucidation of molecular targets and pathways in mitosis are critical for the development of anti-mitotic drugs. Here, we show that cell division cycle 5-like (Cdc5L), a pre-mRNA splicing factor, is a regulator of mitotic progression. Depletion of Cdc5L causes dramatic mitotic arrest, chromosome misalignments and sustained activation of spindle assembly checkpoint, eventually leading to mitotic catastrophe. Moreover, these defects result from severe impairment of kinetochore-microtubule attachment and serious DNA damage. Genome-wide gene expression analysis reveals that Cdc5L modulates the expression of a …

Single Nucleotide Polymorphism Of Srebf-1 Gene Associated With An Increased Risk Of Endometrial Cancer In Chinese Women., Chun-Ping Qiu, Qing-Tao Lv, Samina Dongol, Chenguang Wang, Jie Jiang

Department of Cancer Biology Faculty Papers

AIM: Elevated levels of sterol regulatory element-binding protein-1 (SREBP-1) have been found in endometrial cancer (EC), suggesting that it is essential to the development of EC. Obesity and diabetes have been established as known risk factors of EC, while SREBF-1 gene polymorphisms have also been found to be associated with obesity and type II diabetes. Therefore, we hypothesize that single nucleotide polymorphism (SNP) in SREBF-1 gene may be associated with increased risk of EC.

METHOD: We analyzed the sequence of SREBF-1 in tissue samples from 30 EC cases and 6 benign controls using high throughput method. Based on the primary …

A human xenograft tumor model was established to assess tumor angiogenesis and tumor growth in vivo. Tube formation assay and chorioallantoic membranes assay were used to assess tumor angiogenesis.Results: We …

Substance P Differentially Modulates Firing Rate Of Solitary Complex (Sc) Neurons From Control And Chronic Hypoxia-Adapted Adult Rats, Nicole L. Nichols, Frank L. Powell, Jay B. Dean, Robert W. Putnam

Neuroscience, Cell Biology & Physiology Faculty Publications

NK1 receptors, which bind substance P, are present in the majority of brainstem regions that contain CO₂/H⁺-sensitive neurons that play a role in central chemosensitivity. However, the effect of substance P on the chemosensitive response of neurons from these regions has not been studied. Hypoxia increases substance P release from peripheral afferents that terminate in the caudal nucleus tractus solitarius (NTS). Here we studied the effect of substance P on the chemosensitive responses of solitary complex (SC: NTS and dorsal motor nucleus) neurons from control and chronic hypoxia-adapted (CHx) adult rats. We simultaneously measured intracellular pH …

Complexity Of Interferon-Γ Interactions With Hsv-1, Nancy J. Bigley

Neuroscience, Cell Biology & Physiology Faculty Publications

The intricacies involving the role of interferon-gamma (IFN-γ) in herpesvirus infection and persistence are complex. Herpes simplex virus type 1 (HSV-1) uses a variety of receptors to enter cells and is transported to and from the host cell nucleus over the microtubule railroad via retrograde and anterograde transport. IFN-γ exerts dual but conflicting effects on microtubule organization. IFN-γ stimulates production of suppressors of cytokine signaling 1 and 3 (SOCS1 and SOCS3), which are involved in microtubule stability and are negative regulators of IFN-γ signaling when overexpressed. IFN-γ also interferes with the correct assembly of microtubules causing them to undergo severe …

Exploring The Atomic Structure And Conformational Flexibility Of A 320 Å Long Engineered Viral Fiber Using X-Ray Crystallography., Anshul Bhardwaj, Sherwood R Casjens, Gino Cingolani

Department of Biochemistry and Molecular Biology Faculty Papers

Protein fibers are widespread in nature, but only a limited number of high-resolution structures have been determined experimentally. Unlike globular proteins, fibers are usually recalcitrant to form three-dimensional crystals, preventing single-crystal X-ray diffraction analysis. In the absence of three-dimensional crystals, X-ray fiber diffraction is a powerful tool to determine the internal symmetry of a fiber, but it rarely yields atomic resolution structural information on complex protein fibers. An 85-residue-long minimal coiled-coil repeat unit (MiCRU) was previously identified in the trimeric helical core of tail needle gp26, a fibrous protein emanating from the tail apparatus of the bacteriophage P22 virion. Here, …

A New Rhesus Macaque Assembly And Annotation For Next-Generation Sequencing Analyses, Aleksey V. Zimin, Adam S. Cornish, Mnirnal D. Maudhoo, Robert M. Gibbs, Xiongfei Zhang, Sanjit Pandey, Daniel T. Meehan, Kristin Wipfler, Steven E. Bosinger, Zachary P. Johnson, Gregory K. Tharp, Guillaume Marçais, Michael Roberts, Betsy Ferguson, Howard S. Fox, Todd Treangen, Steven L. Salzberg, James A. Yorke, Robert B. Norgren Jr.

Journal Articles: Genetics, Cell Biology & Anatomy

BACKGROUND: The rhesus macaque (Macaca mulatta) is a key species for advancing biomedical research. Like all draft mammalian genomes, the draft rhesus assembly (rheMac2) has gaps, sequencing errors and misassemblies that have prevented automated annotation pipelines from functioning correctly. Another rhesus macaque assembly, CR_1.0, is also available but is substantially more fragmented than rheMac2 with smaller contigs and scaffolds. Annotations for these two assemblies are limited in completeness and accuracy. High quality assembly and annotation files are required for a wide range of studies including expression, genetic and evolutionary analyses.

RESULTS: We report a new de novo assembly of the …

Identification And Characterization Of Downstream Effector Protein(S) Regulated By P53 And Prb, Miranda B. Carper

Theses, Dissertations and Capstones

A commonality among cancer types is the high frequency of mutations that inhibit or alter signaling of the p53 and pRb (Retinoblastoma) tumor suppressors. These genes regulate processes vital for cancer suppression such as apoptosis, senescence, and cell cycle arrest among others. Loss of both p53 and pRb promotes processes that support cancer progression and is associated with decreased patient survival and increased rates of tumor reoccurrence. Although data points to the ability of p53 and pRb to collaborate and to inhibit tumorigenesis, it remains unclear how p53 and pRb cooperate toward this task. Using RNA expression profiling, 179 p53 …

Complement Expression In The Retina Is Not Influenced By Short-Term Pressure Elevation, Konstantin Astafurov, Cecilia Q. Dong, Lampros Panagis, Gautam Kamtham, Lizhen Ren, Anna Rozenboym, Tarique D. Perera, Jeremy D. Coplan, John Danias

RNA and protein were extracted and used for analysis of expression levels of complement component genes and complement component 1, q subcomponent (C1q) and comple- ment factor H (CFH) immunoblotting. …

Computational Analysis Of Transcriptional Circuitries In Human Embryonic Stem Cells Reveals Multiple And Independent Networks, Xiaosheng Wang, Chittibabu Guda

Journal Articles: Genetics, Cell Biology & Anatomy

It has been known that three core transcription factors (TFs), NANOG, OCT4, and SOX2, collaborate to form a transcriptional circuitry to regulate pluripotency and self-renewal of human embryonic stem (ES) cells. Similarly, MYC also plays an important role in regulating pluripotency and self-renewal of human ES cells. However, the precise mechanism by which the transcriptional regulatory networks control the activity of ES cells remains unclear. In this study, we reanalyzed an extended core network, which includes the set of genes that are cobound by the three core TFs and additional TFs that also bind to these cobound genes. Our results …

Benzyl Isothiocyanate As An Adjuvant Chemotherapy Option For Head And Neck Squamous Cell Carcinoma, Mary Allison Wolf

Theses, Dissertations and Capstones

Isothiocyanates (ITCs) are natural phytochemicals produced by cruciferous vegetables. Recent evidence supports that, in addition to cancer prevention, ITCs can use various mechanisms to target malignant cells. Current therapies for cancer often provoke detrimental side effects, however clinical evidence supports that ITCs have little to no side effects in patients. Consequently, ITCs may be a promising treatment option for cancer patients, especially patients suffering from head and neck squamous cell carcinoma (HNSCC).

Despite recent improvements in cancer treatment, overall survival of advanced HNSCC has not improved in the past three decades. Metastasis and chemoresistance represent two detrimental events that greatly …
