The Role Of Bca2 In Regulation Of Warburg-Like Glucose And Lactate Metabolism In Breast Cancer Cell Lines, Richard T. Arkwright Iii Jan 2020

The Role Of Bca2 In Regulation Of Warburg-Like Glucose And Lactate Metabolism In Breast Cancer Cell Lines, Richard T. Arkwright Iii

Wayne State University Dissertations

Modified metabolism is a hallmark of cancer cell biology known as “The Warburg Effect,” characterized by increased glucose-consumption and lactate-production, providing the metabolites and energy necessary for rapid proliferation. Breast-cancer-associated-gene-2 (BCA2) is an E3-Ub-ligase known to modulate AMPK, the “master-regulator of energy-homeostasis.” BCA2 is an oncogene associated with poor patient-survival and breast cancer invasiveness. Phospho-proteomic analysis of siBCA2-MDA-MB-231 knockdown-(KD) revealed enrichment of Nicotinamide-Nucleotide-Adenylyl-transferase-1 (NMNAT1), an essential enzyme in nuclear NAD-synthesis and a tumor-suppressor.

Initial experiments demonstrated that glucose concentration was positively correlated with BCA2 and inversely with NMNAT1 protein expression. shBCA2-KD in MDA-MB-468/-231 reproduced the inverse correlation between BCA2 and …

Epithelial-to-mesenchymal transition (EMT) is one of the important underlying molecular mechanisms for most types of cancers including bladder cancer. The precise underlying molecular mechanism in EMT-mediated bladder cancer progression is far from completed. LSD1, a histone lysine-specific demethylase, is known to promote cancer cell proliferation, metastasis, and chemoresistance. We found in this study that LSD1 is highly upregulated in bladder cancer specimens, especially those underwent chemotherapy, and the elevated levels of LSD1 are highly associated with bladder cancer grades, metastasis status, and prognosis. Inhibiting or knockdown LSD1 repressed not only EMT process but also cancer progression. Mechanistically, LSD1 complexes with …

PCOM Scholarly Works

Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors originating from chromaffin cells in the adrenal medulla (PCCs) or extra-adrenal sympathetic or parasympathetic paraganglia (PGLs). About 40% of PPGLs result from germline mutations and therefore they are highly inheritable. Although dysfunction of any one of a panel of more than 20 genes can lead to PPGLs, mutations in genes involved in the VHL/HIF axis including

A High Docosahexaenoic Acid Diet Alters The Lung Inflammatory Response To Acute Dust Exposure, Edward C. Dominguez, Art J. Heires, Jacqueline A. Pavlik, Tricia D. Larsen, Stephanie Guardado, Joseph H. Sisson, Michelle L. Baack, Debra J. Romberger, Tara M. Nordgren

Journal Articles: Internal Medicine

Agricultural workers are at risk for the development of acute and chronic lung diseases due to their exposure to organic agricultural dusts. A diet intervention using the omega-3 fatty acid docosahexaenoic acid (DHA) has been shown to be an effective therapeutic approach for alleviating a dust-induced inflammatory response. We thus hypothesized a high-DHA diet would alter the dust-induced inflammatory response through the increased production of specialized pro-resolving mediators (SPMs). Mice were pre-treated with a DHA-rich diet 4 weeks before being intranasally challenged with a single dose of an extract made from dust collected from a concentrated swine feeding operation (HDE). …

Targeting The Tumor Core: Hypoxia-Responsive Nanoparticles For The Delivery Of Chemotherapy To Pancreatic Tumors, Matthew I. Confeld, Babak Mamnoon, Li Feng, Heather Jensen Smith, Priyanka Ray, James Froberg, Jiha Kim, Michael A. Hollingsworth, Mohiuddin Quadir, Yongki Choi, Sanku Mallik

Journal Articles: Eppley Institute

In pancreatic ductal adenocarcinoma (PDAC), early onset of hypoxia triggers remodeling of the extracellular matrix, epithelial-to-mesenchymal transition, increased cell survival, the formation of cancer stem cells, and drug resistance. Hypoxia in PDAC is also associated with the development of collagen-rich, fibrous extracellular stroma (desmoplasia), resulting in severely impaired drug penetration. To overcome these daunting challenges, we created polymer nanoparticles (polymersomes) that target and penetrate pancreatic tumors, reach the hypoxic niches, undergo rapid structural destabilization, and release the encapsulated drugs. In vitro studies indicated a high cellular uptake of the polymersomes and increased cytotoxicity of the drugs under hypoxia compared to …

Targeting Homologous Recombination Addicted Tumors: Challenges And Opportunities, Talia Golan, Jonathan Brody, Md

Kimmel Cancer Center Faculty Papers

Recent advances in next generation sequencing (NGS) and molecular subtyping of tumors have opened the door to clinically available targeted therapies. Although the treatment of many solid tumors still rely on a steady regimen of non-targeted chemotherapeutic agents, it is becoming increasingly more apparent that certain tumors with defects in DNA damage repair (DDR) genes may be exquisitely sensitive to DNA damaging agents or therapies targeting key elements of this pathway such PARP1, ATR, or ATM. Still, for tumors with DDR defects the challenges are multi-fold including: (I) identifying these tumors in patients in time for a window of opportunity …

Myo/Nog cells were discovered in the chick embryo epiblast. Their expression of MyoD reflects a commitment to the skeletal muscle lineage and capacity to differentiate into myofibroblasts. Release of Noggin by Myo/Nog cells is essential for normal morphogenesis. Myo/Nog cells rapidly respond to wounding in the skin and eyes. In this report, we present evidence suggesting that Myo/Nog cells phagocytose tattoo ink in tissue sections of human skin and engulf cell corpses in cultures of anterior human lens tissue and magnetic beads injected into the anterior chamber of mice in vivo. Myo/Nog cells are distinct from macrophages in the skin …


Investigation Of Molecular Mechanisms Of Liver Preservation Injury: A Complication Preceding Organ Transplantation, Ria C. Fyffe-Freil Jan 2020

Investigation Of Molecular Mechanisms Of Liver Preservation Injury: A Complication Preceding Organ Transplantation, Ria C. Fyffe-Freil

Theses and Dissertations

Of the over 108,000 American awaiting a life-saving organ transplant today, over 12,000 (11%) of those need a new liver (OPTN, 2020). Last year, only 35% of patients on the waiting list for an organ were transplanted. Improving the quality of marginal organs by preventing or reversing preservation injury could vastly increase the number of transplants performed. Washout of circulating blood during liver procurement with cold University of Wisconsin solution flushes out any endogenous pro-survival signaling molecules. We investigated lysophospholipid (LPL) surface receptors (G-protein coupled receptors for lysophosphatidic acid (LPA) and sphingosine- 1-phosphate (S1P)) and their role in protecting hepatocytes …


Role Of Nurd In Acute Leukemia Cell Survival, Javeria Aijaz Jan 2020

Role Of Nurd In Acute Leukemia Cell Survival, Javeria Aijaz

Theses and Dissertations

Depletion of the ATPase component of the Nucleosome Remodeling and Deacetylase (NuRD) complex, CHD4, reduces acute myeloid leukemia (AML) cell survival. This study identified other NuRD components, as potential therapeutic targets for disrupting protein-protein interactions within NuRD. In addition to AML, we established that T-cell Acute Lymphoblastic Leukemia (T-ALL) cell lines responded similarly to CHD4 depletion.

Greater than 90% depletion of either MBD2 or MBD3 (the mutually exclusive two DNA binding NuRD paralogues) – was unremarkable, but complete depletion of MBD3 increased apoptosis and genotoxic sensitivity. Combined depletion of MBD-NuRD proteins augmented apoptosis observed with complete MBD3 depletion - indicating …

Characterizing Glycosaminoglycan And Glycosaminoglycan-Oligo Interactions With Cancer Stem Cells And Their Regulators, Rahaman Navaz Gangji

Theses and Dissertations

Tumor metastasis and recurrence account for more than 90% of cancer-associated deaths and are thought to occur due to a small subpopulation of neoplastic cells known as cancer stem cells (CSCs). Because CSCs are resistant to conventional chemotherapy, there is a critical need to develop CSC-targeting agents. Microenvironmental components, especially glycosaminoglycans (GAGs), play a key role in regulating CSC phenotype. GAGs such as heparan sulfate (HS) interact with hundreds of proteins and influence a variety of biological processes including tumor proliferation, angiogenesis, metastasis and stem cell biology.

Recently, the Desai and Patel laboratories have demonstrated that a hexasaccharide form of …


Development Of A Torque-Based Device For The Quantification Of Arm Rigidity In Patients With Parkinson’S Disease, Georgina O. Miller Jan 2020

Development Of A Torque-Based Device For The Quantification Of Arm Rigidity In Patients With Parkinson’S Disease, Georgina O. Miller

Theses and Dissertations

Parkinsonian rigidity is caused by the inability of the muscles to relax and extend properly, due to reduced dopamine levels and often begins on one side of the body before spreading contralaterally. The current standard for determining joint rigidity in a clinical setting is a test completed by the clinician based on the feel of the relaxed wrist and elbow joints as they are passively flexed and extended and a series of ordinal rating scales, the Movement Disorder Society’s – Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), Hoehn and Yahr Scale (H&Y), and Parkinson’s Disease Questionnaire-39 (PDQ-39). These methods are used …

Isolation And Characterization Of Α-Gal-Containing Extracellular Vesicles (Evs) From Three Major Genotypes Of Trypanosoma Cruzi: Potential Biomarkers Of Chagas Disease, Nasim Karimi Hosseini

Open Access Theses & Dissertations

Chagas disease (ChD) is a neglected tropical disease (NTD) caused by the protozoan parasite, Trypanosoma cruzi. It is transmitted by the insect-vector triatomine (popular known as kissing bug), blood transfusion, organ transplantation, congenitally, and contaminated foods and juices. T. cruzi has evolved several strategies to invade the host cells, including the release extracellular vesicles (EVs), which assist pathogen survival and its replication within the host. T. cruzi is covered with highly glycosylated surface molecules such as glycoproteins and glycolipids, which are shown to be involved in the interaction with host immune cells. These molecules are highly immunogenic and reactive with …


Targeting Epha2 In Hepatocellular Carcinoma: Uncovering Its Therapeutic Potential And Beyond, Hao Wang Jan 2020

Targeting Epha2 In Hepatocellular Carcinoma: Uncovering Its Therapeutic Potential And Beyond, Hao Wang

Dissertations

Hepatocellular Carcinoma (HCC) remains one of the deadliest malignancies worldwide. One major obstacle to treatment is a lack of effective molecular-targeted therapies. Here, we identify EphA2 receptor tyrosine kinase as a clinically relevant target for HCC. EphA2 expression and signaling is enriched in human HCC and associates with poor prognosis. Loss of EphA2 suppressed the initiation and growth of HCC in vitro and in vivo. Furthermore, CRISPR/CAS9 mediated EphA2 inhibition significantly delayed tumor development in a genetically-engineered murine model of HCC. Mechanistically, we discovered that targeting EphA2 simultaneously suppresses both JAK1/STAT3 and AKT signaling, two separate oncogenic pathways in HCC. …

Coagulopathy often develops soon after acute traumatic brain injury and its cause remains poorly understood. We have shown that injured brains release cellular microvesicles that disrupt the endothelial barrier and induce consumptive coagulopathy. Morphologically intact extracellular mitochondria accounted for 55.2% of these microvesicles, leading to the hypothesis that these extracellular mitochondria are metabolically active and serve as a source of oxidative stress that activates platelets and renders them procoagulant. In testing this hypothesis experimentally, we found that the extracellular mitochondria purified from brain trauma mice and those released from brains subjected to freeze-thaw injury remained metabolically active and produced reactive …

Background: Children with nephrotic syndrome (NS) are at high risk for vaccine-preventable infections due to the immunological effects from the disease and concurrent treatment with immunosuppressive medications. Immunizations in these patients may be deferred due to their immunosuppressive treatment which may increase the risk for vaccine-preventable infections. Immunization practices in children with NS continue to vary among pediatric nephrologists. This raises the question of whether children with NS are receiving the recommended vaccinations at appropriate times. Therefore, it is critical to understand the practices and patient education provided by physicians to patients on the topic of vaccinations.

Methods: After informed …

Faculty, Staff and Student Publications

Among 170 adults with sickle cell disease, we evaluated chronic pain impact and disability prevalence, assessed age and gender differences, and identified psychosocial predictors of chronic pain intensity and disability. Most participants had a high level of disability. Chronic pain intensity and disability were significantly associated with pain catastrophizing and chronic pain self-efficacy, and worsened with age. Further research is needed to confirm study findings and develop interventions, including palliative care approaches that address catastrophizing and disability, particularly for young women and middle-aged adults with sickle cell disease. Moreover, consistent clinical assessment of chronic pain and psychosocial health should be …
