Metadherin Functions As A Laminin Receptor That Is Essential For Metastasis And Is Associated With Poor Survival In Osteosarcoma, Limin Zhu

Dissertations and Theses (Open Access)

Osteosarcoma is a highly invasive bone malignancy in which metastasis accounts for the vast majority of death and morbidity in patients. Understanding the mechanisms controlling metastasis is essential for improving patient survival in this disease. In order to improve the clinical outcomes for patients with poor prognosis, it is urgent to find new therapeutic targets to block metastasis in this disease. Recent studies have shown that Metadherin (MTDH) plays an essential role in mediating tumorigenesis and metastasis in a variety of human cancers. Our study assessed the role of MTDH in osteosarcoma metastasis and elucidated the mechanisms underlying its metastasis-promoting …

Anti-Insulin Resistance Treatments Suppress Her2+ Breast Cancer Growth Via Altering Metabolism, Ping-Chieh Chou

Dissertations and Theses (Open Access)

Epidemiological studies have identified that type 2 diabetes mellitus (DM2) is a significant risk factor for carcinogenesis and cancer death, including breast cancer. Our previous finding in patients showed that anti-insulin resistance treatments are associated with improved HER2⁺ breast cancer survival of diabetic women. However, there were no transgenic mouse models to study the correlation and explain the detailed mechanism. We generated a mouse model of HER2⁺ breast cancer with DM2 by crossing leptin receptor point mutation (Lepr ^db/+) and MMTV-ErbB2 (neu) mice. The MMTV-ErbB2/Lepr ^db/db mice had a poor survival rate compared …

Diabetes And Obesity Induce Transcriptomic And Metabolomic Changes Enhancing Pancreatic Cancer Aggressiveness, Guermarie Velázquez Torres

Dissertations and Theses (Open Access)

Pancreatic cancer is one of the most aggressive types of cancer, with poor prognosis that lacks effective diagnostic markers and therapies. It is expected that in 2014 the incidence and the mortality of pancreatic cancer in the United States will be 46,420 and 39,590 respectively. Diabetes and obesity are modifiable risk factors associated with accelerated pancreatic carcinogenesis and tumor progression, but the biological mechanisms are not completely understood. The purpose of this study is to demonstrate direct evidence for the mechanisms mediating these epidemiologic phenomena. Our hypothesis is that obesity and diabetes mellitus type 2 (DM2) accelerate pancreatic cancer and …

Car-Modified T Cells Capable Of Distinguishing Normal Cells From Malignant Cells, Hillary G. Caruso

Dissertations and Theses (Open Access)

T cells can be redirected to target tumor-associated antigen (TAA) by genetic modification to express a chimeric antigen receptor (CAR), which fuses the specificity derived from an antibody to T-cell activation domains to result in lysis of TAA-expressing cells. Due to the potential for on-target, off-tissue toxicity, CAR⁺ T-cell therapy is currently limited to unique or lineage-restricted TAAs. Glioblastoma, a grade IV brain malignancy, overexpresses epidermal growth factor receptor (EGFR) in 40-50% of patients. EGFR also has widespread normal tissue expression. To target EGFR on glioblastoma while reducing the potential for normal tissue toxicity, EGFR-specific CAR generated from cetuximab, …

The Regulation Of Microrna Biogenesis By Ribosome-Interacting Proteins, Brian Pickering

Dissertations and Theses (Open Access)

MicroRNA (miRNA) are small, non-coding RNAs that affect gene expression through degradation of complementary mRNA targets or inhibition of translation. As they affect approximately 50% of all cellular processes, miRNA are tightly regulated by the cell through transcriptional and post-transcriptional mechanisms. Transcribed miRNA are capped and polyadenylated (referred to as pri-miRNA) which are cleaved by Drosha and DGCR8 to generate 60-90 nucleotide precursor miRNA. The precursors are cleaved again by Dicer and loaded into the RNA-induced silencing complex (RISC) of which Argonaute 2 is the functional component. Many of the proteins involved in miRNA biogenesis share a common role in …

Regulation Of Mammary Gland Development And Tumorigenesis By 14-3-3 Zeta, Sumaiyah Rehman

Dissertations and Theses (Open Access)

Signaling pathways that play critical roles in organ development are often aberrantly regulated during cancer initiation and progression. 14-3-3z is overexpressed in more than 40% of breast cancers and is associated with poor patient prognosis. Therefore, the function of 14-3-3z in cancer and normal mammary gland development was investigated utilizing multiple in vivo and in vitro approaches. 14-3-3z is a chaperone protein that interacts with a multitude of oncogenes and tumor suppressor genes, thereby functioning as a critical node in multiple oncogenic signaling networks. Mammary gland-specific 14-3-3z transgenic mouse models showed that 14-3-3z overexpression was sufficient to induce mammary tumorigenesis. …

Sumoylation Status And Effects Of Sumylation On Dax-1, Amy E. Scandurra, Hai Nguyen, Christina Tzagarakis -­‐Foster

Creative Activity and Research Day - CARD

DAX-1 (Dosage Sensitive Sex Reversal Adrenal Hypoplasia Congenita on the X Chromosome gene 1) is a Nuclear Hormone Receptor, which acts as a transcriptional repressor in the nucleus. DAX-1 plays an important role in development and also appears to have some influence on the progression of cancer. In an effort to better understand DAX-1 function both in normal and disease states we are examining one type of posttranslational modification, SUMOylation. SUMOylation involves the addition of the small polypeptide conjugate SUMO (Small Ubiquitin-like Modifier) to proteins, this can have a variety of effects on protein activity. To …

The Effects Of Gold Nanorods On The Rate Of Apoptosis Of Triple Negative Breast Cancer Cells, Mattie E. Raiford

Honors College Theses

Triple negative breast cancer (TNBC) is a subtype of breast cancer that is most often found in African American females that is characterized by the lack of the progesterone receptor (PR), the estrogen receptor (ER), and the human epithelial growth factor receptor two (HER2).TNBC is a very aggressive form of breast cancer because it does not respond to hormone therapy, due to the lack of the three vital receptors. Since the current treatment is not affective, the project used porphyrin to specifically target cancer in the body because it has an increased affinity for many cancer types. Gold nanorods were …

Analysis Of The Regulation And Function Of Cip2a To Identify Candidate Biomarkers For Prostate Cancer, Diana Savoly

Graduate School of Biomedical Sciences Theses and Dissertations

Protein Phosphatase 2A (PP2A) is a tumor suppressor involved in the regulation of several signaling pathways and the cell cycle. PP2A becomes inactivated by several inhibitors, including Cancerous Inhibitor of PP2A (CIP2A). CIP2A has been identified as an oncogene, which is over-expressed in cancers and inhibits PP2A through direct interaction. CIP2A is recognized as a biomarker for cancer; however, it is not cancer-specific. Therefore, we identified and examined the use of CIP2A-regulated proteins as potential biomarkers in prostate cancer to better diagnose prostate cancer in patients. Currently, Prostate Specific Antigen (PSA) is widely used to detect prostate cancer; however, it …

Molecular Pap Biomarkers For Cervical Cancer Risk Assessment In Thinprep® Clinical Specimens, Jennifer Taylor

Graduate School of Biomedical Sciences Theses and Dissertations

Approximately 500,000 patients are diagnosed with cervical cancer worldwide each year, thus making it the second most common cause of cancer-related deaths in women. Persistent high-risk human papillomavirus (HR-HPV) infections induce cervical dysplasia by increasing the expression of two viral oncogenes, E6 and E7. Utilization of the Papanicolaous smear test (Pap test) has contributed to a decrease in morbidity and mortality of cervical cancer; however, subjective analysis of cell morphology with a limited amount of cells has led to a substantial rate of false positive and false negative diagnoses. A more objective and sensitive diagnostic tool for the detection of …

A Melanin-Independent Interaction Between Mc1r And Met Signalling Pathways Is Required For Hgf-Dependent Melanoma, Agnieszka Wolnicka-Głubisz, Faith M. Strickland, Albert Wielgus, Miriam Anver, Glenn Merlino, Edward C. De Fabo, Frances P. Noonan

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Melanocortin 1 receptor (MC1R) signaling stimulates black eumelanin production through a cAMP-dependent pathway. MC1R polymorphisms can impair this process, resulting in a predominance of red phaeomelanin. The red hair, fair skin and UV sensitive phenotype is a well-described melanoma risk factor. MC1R polymorphisms also confer melanoma risk independent of pigment. We investigated the effect of Mc1r deficiency in a mouse model of UV-induced melanoma. C57BL/6-Mc1r+/+-HGF transgenic mice have a characteristic hyperpigmented black phenotype with extra-follicular dermal melanocytes located at the dermal/epidermal junction. UVB induces melanoma, independent of melanin pigmentation, but UVA-induced and spontaneous melanomas are dependent on black eumelanin. We …

Public Health, Health Administration, and Health Sciences Faculty Research

Biomarkers of selenium are necessary for assessing selenium status in humans, since soil variation hinders estimation of selenium intake from foods. In this study, we measured the concentration of plasma selenium, selenoprotein P (SEPP1), and glutathione peroxidase (GPX3) activity and their interindividual differences in 383 low-income blacks and whites selected from a stratified random sample of adults aged 40–79 years, who were participating in a long-term cohort study in the southeastern United States (US). We assessed the utility of these biomarkers to determine differences in selenium status and their association with demographic, socio-economic, dietary, and other indicators. Dietary selenium intake …

The Role Of Mammalian Cyclin C In Stress Response And Thyroid Disease Progression, Kun Wang

Graduate School of Biomedical Sciences Theses and Dissertations

The cellular response to stress involves changes in gene expression programs as well as the remodeling of subcellular organelles including the mitochondria. Important for this study, the mitochondria undergo extensive fragmentation when the cell is exposed to a variety of stressors. The cyclin C-Cdk8 kinase is a highly conserved transcription factor that associates with the RNA polymerase II holoenzyme. Using cyclin C knockout (CCNC^-/-) mouse embryonic fibroblast (MEF) cells, I revealed that cyclin C is required for the extensive mitochondrial fragmentation following treatment with pro-oxidants or the anti-cancer drug cisplatin. However, Cdk8 is not required for this process …

Paracrine-Rescued Lobulogenesis In Chimeric Outgrowths Comprising Progesterone-Receptor-Null Mammary Epithelium And Redirected Wild-Type Testicular Cells, Robert D. Bruno, Corinne A. Boulanger, Sonia M. Rosenfield, Lisa H. Anderson, John P. Lydon, Gilbert H. Smith

School of Medical Diagnostics & Translational Sciences Publications

We have previously shown that non-mammary and tumorigenic cells can respond to the signals of the mammary niche and alter their cell fate to that of mammary epithelial progenitor cells. Here we tested the hypothesis that paracrine signals from mammary epithelial cells expressing progesterone receptor (PR) are dispensable for redirection of testicular cells, and that re-directed wild-type testicular-derived mammary cells can rescue lobulogenesis of PR-null mammary epithelium by paracrine signaling during pregnancy. We injected PR-null epithelial cells mixed with testicular cells from wild-type adult male mice into cleared fat-pads of recipient mice. The testicular cells were redirected in vivo to …

Cancellation Of Cellular Responses To Nanoelectroporation By Reversing The Stimulus Polarity, Andrei G. Pakhomov, Iurii Semenov, Shu Xiao, Olga N. Pakhomova, Betsy Gregory, Karl H. Schoenbach

Bioelectrics Publications

Nanoelectroporation of biomembranes is an effect of high-voltage, nanosecond-duration electric pulses (nsEP). It occurs both in the plasma membrane and inside the cell, and nanoporated membranes are distinguished by ion-selective and potential-sensitive permeability. Here we report a novel phenomenon of bioeffects cancellation that puts nsEP cardinally apart from the conventional electroporation and electrostimulation by milli- and microsecond pulses. We compared the effects of 60- and 300-ns monopolar, nearly rectangular nsEP on intracellular Ca²⁺mobilization and cell survival with those of bipolar 60 + 60 and 300 + 300 ns pulses. For diverse endpoints, exposure conditions, pulse numbers (1-60), and …

The Effect Of Lactic Acid On Mast Cell Function, Andrew J. Spence

Theses and Dissertations

This study shows for the first time the effect that L-(+)-lactic acid has on mast cell activation. Lactic acid is a byproduct of anaerobic glycolysis and is associated with inflammatory environments such as wounds, tumors and, asthma. In this study, pre-treatment with lactic acid altered cytokine production by bone marrow-derived mast cells (BMMC). Specifically, lactic acid enhanced cytokine secretion following IgE cross-linking, but decreased IL-33 mediated cytokine production. These effects were altered by genetic background, since C57BL/6 mast cells demonstrated the aforementioned result, but lactic acid had no effect on IgE-mediated cytokine production in 129/SvJ mast cells. The affected cytokines …

In this study, we provide a detailed structural classification and analysis of functional dynamics for members of protein kinase families that are known to harbor cancer mutations. We also present a systematic computational analysis that combines sequence and structure-based prediction models to characterize the effect of cancer mutations in protein kinases. We focus on the differential effects of activating point mutations that increase protein kinase activity and kinase-inactivating mutations that decrease activity. Mapping of cancer mutations onto the conformational …

Analysis Of The Role Of Two Autophagy Pathway Related Genes, Becn1 And Tsc1, In Murine Mammary Gland Development And Differentiation, Amber N. Hale

Theses and Dissertations--Biology

The mammary gland is a dynamic organ that undergoes the majority of its development in the postnatal period in four stages; mature virgin, pregnancy, lactation, and involution. Every stage relies on tightly regulated cellular proliferation, programmed cell death, and tissue remodeling mechanisms. Misregulation of autophagy, an intracellular catabolic process to maintain energy stores, has long been associated with mammary tumorigenesis and other pathologies. We hypothesize that appropriate regulation and execution of autophagy are necessary for proper development of the mammary ductal tree and maintenance of the secretory epithelia during late pregnancy and lactation. To test this hypothesis we examined the …

Effect Of Heme Oxygenase-1 On Matrix Metalloproteinase-3 Expression In Human Fibroblasts, Theresa A. Stangl

PCOM Biomedical Studies Student Scholarship

Heme oxygenase-1(HO-1) is an enzyme that plays a very important role in the resolution of inflammation. HO-1-based therapies are effective in a number of disease conditions. However, HO-1 also increases tumor growth, angiogenesis, metastasis and chemoresistance. Matrix metalloproteinase-3 (MMP-3) is an enzyme involved in physiological and pathophysiological tissue remodeling. Unbalanced expression of MMPs is a key feature of connective tissue destruction in chronic inflammatory conditions. Previously shown in this laboratory, the HO-1 inducer, hemin, increased MMP-3 mRNA expression in some HGF cultures. To assess whether HO-1 and/or its products regulate expression of MMP-3 in human fibroblasts, the effect of HO-1 …

Beta-Alanine Suppresses Malignant Breast Epithelial Cell Aggressiveness Through Alterations In Metabolism And Cellular Acidity In Vitro, Roger A. Vaughan, Nicholas P. Gannon, Randi Garcia-Smith, Yamhilette Licon-Munoz, Miguel A. Barberena, Marco Bisoffi, Kristina A. Trujillo

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Background: Deregulated energetics is a property of most cancer cells. This phenomenon, known as the Warburg Effect or aerobic glycolysis, is characterized by increased glucose uptake, lactate export and extracellular acidification, even in the presence of oxygen. beta-alanine is a non-essential amino acid that has previously been shown to be metabolized into carnosine, which functions as an intracellular buffer. Because of this buffering capacity, we investigated the effects of beta-alanine on the metabolic cancerous phenotype.

Methods: Non-malignant MCF-10a and malignant MCF-7 breast epithelial cells were treated with beta-alanine at 100 mM for 24 hours. Aerobic glycolysis was quantified …

Investigating The Role Of Dachshund Homolog 1 (Dach1) And Mir-200b In Group 4 Medulloblastoma Pathogenesis, Courtney George

Theses : Honours

Medulloblastoma is the most common malignant childhood brain tumour, and the most significant cause of childhood cancer-related mortality. Recently four core molecular medulloblastoma sub-groups have been identified, with distinct pathogenesis and responses to therapies. Current therapies, do not account for this molecular variation, and many patients may receive inappropriate treatment. To address this, targeted therapies for each molecular sub-group would be ideal. Unfortunately, for the more aggressive Group 3 and Group 4 subgroups, the underlying mechanisms of pathogenesis remain poorly understood. The current challenge is to identify the key tumour suppressors or oncogenes involved in Group 3 and Group 4 …

Effects Of Keratin Filaments On Erk Signaling During Fas-Induced Death Of Cervical Cancer (Hela) Cells, Amanda Berger

Honors Theses and Capstones

Survival of cancer cells is influenced by a variety of factors, including physical elements such as keratin filaments. We know HeLa cells containing or lacking keratin 8/18 intermediate filaments (K+ and K- cells, respectively) are more sensitive to the death-inducing effects of Fas agonist compared to the cytokines tumor necrosis factor alpha (TNF-α) or TNF-related apoptosis-inducing ligand. Additionally, K- cells are more sensitive to Fas-induced death than K+ as shown by previous studies using mitochondrial activity and caspase activation assays. In the current study we tested the hypothesis that keratin filaments associate with the mitogen activated protein kinase (MAPK) cascade …

Synthetic Triterpenoids Can Protect Against Toxicity Without Reducing The Efficacy Of Treatment With Carboplatin And Paclitaxel In Experimental Lung Cancer, Karen T. Liby

Dartmouth Scholarship

Synthetic oleanane triterpenoids are multifunctional drugs being developed for the prevention and treatment of a variety of chronic diseases driven by inflammation and oxidative stress. Low nanomolar concentrations of triterpenoids inhibit the induction of inflammatory cytokines, and these drugs are potent activators of the Nrf2 cytoprotective pathway. In contrast, low micromolar concentrations of triterpenoids increased the production of ROS and induced apoptosis in a dose-dependent manner in malignant MCF10 CA1a breast cancer cells. Because cancer cells respond differently to ROS than normal cells, it should be possible to exploit these differences therapeutically. In an experimental model of lung cancer, the …
