Aurka Inhibition-Based Combination Therapy Approaches In Glioblastoma., Muge Sak
Aurka Inhibition-Based Combination Therapy Approaches In Glioblastoma., Muge Sak
Electronic Theses and Dissertations
Glioblastoma is the most common and aggressive central nervous system tumor in adults with a 6% survival rate. Decades of research for improving life expectancy and quality of life have been ineffective. The discovery of better treatment strategies is urgent to improve the survival rates for glioblastoma patients. Aurora Kinase A is a regulator of tumor progression and is overexpressed in glioblastoma. We used a specific Aurora Kinase A inhibitor alisertib in combination with DNA-damaging platinum agent carboplatin or brain-penetrating taxane TPI 287. We investigated the efficacy of these combinations in treating in vitro and in vivo tissue culture models …
Clinical And Environmental Factors Affecting The Survival Outcomes Among Stage 1a Tn0m0 First Primary Non-Small Cell Lung Carcinoma Patients In The United States., Naiya Patel
Electronic Theses and Dissertations
Background: Lung cancer is the second leading cause of death in the United States (U.S.). The most prevalent histological type of lung cancer is Non-Small Cell Lung Cancer (NSCLC), which has an overall five years survival of 5% if left untreated. Therefore, early treatment of NSCLC is vital to improve overall survival (OS) outcomes. Several factors affect survival outcomes, which can be categorized as modifiable or non-modifiable. The difference in timely receipt of guideline-concordant treatment affects the survival outcomes of patients with stage 1A NSCLC. This dissertation explored factors that affect treatment and survival outcomes among stage 1A NSCLC patients …
The Role Of Obesity In Macrophage-Mediated Mechanisms Promoting Early-Onset Colon Cancer., Katharina Marietta Scheurlen
The Role Of Obesity In Macrophage-Mediated Mechanisms Promoting Early-Onset Colon Cancer., Katharina Marietta Scheurlen
Electronic Theses and Dissertations
Early-onset colon cancer (EOCC) is a leading cause of cancer death among people younger than 50 years of age in the United States and is associated with metabolic dysfunction and obesity. Anti-inflammatory tumor-associated macrophages (TAM) and low Peroxisome Proliferator Activated Receptor Gamma (PPARγ) gene expression in colon cancer (CC) tissue promote tumor progression and decreased patient survival. Obesity-related hormones, such as leptin and adiponectin, have the potential to affect gene expression in TAM to promote CC progression and thereby link obesity and EOCC. The aim of this project was to identify target genes in human CC and to investigate the …
Harnessing The Power Of Trained Immunity In The Setting Of Pancreatic Cancer: A Novel Mechanism Of Immune Trafficking And Tumor Control., Anne Elena Geller
Harnessing The Power Of Trained Immunity In The Setting Of Pancreatic Cancer: A Novel Mechanism Of Immune Trafficking And Tumor Control., Anne Elena Geller
Electronic Theses and Dissertations
Despite the success of immunotherapy in many types of cancer, pancreatic adenocarcinoma (PDAC) has yet to benefit. Innate immune cells are critical to antitumor immunosurveillance and recent studies have revealed that these populations possess a form of memory, termed trained innate immunity, which occurs through transcriptomic, epigenetic, and metabolic reprograming. Though trained innate immunity has mostly been investigated in the context of infection, the induction of trained innate immunity could also protect against tumors, and specifically pancreatic tumors. Here, we demonstrate that yeast-derived particulate β-glucan, a known inducer of trained immunity, traffics to the pancreas following IP administration. This causes …
Wnt/Β-Catenin Mediated Cancer Stem Cell Activation In Hepatocellular Carcinoma., Harshulkumar M. Pandit
Wnt/Β-Catenin Mediated Cancer Stem Cell Activation In Hepatocellular Carcinoma., Harshulkumar M. Pandit
Electronic Theses and Dissertations
Hepatocellular carcinoma (HCC) is one of the deadliest cancers, with variable presentation, high chemotherapy resistance and early tumor recurrence. In this dissertation, we have systematically enriched, identified and characterized HCC cancer stem cells (CSCs) from 3 different HCC cell lines (Hepa1-6, HepG2, and Hep3B) using in vitro serum-free culture method. Enriched spheroids acquired CSC properties, primarily self-renewal capability, spheroid formation ability, and drug resistance. Heterogeneous CSCs enriched from Hepa1-6 cells demonstrated higher tumor initiation and proliferation capability in vivo, compared to control HCC cells in orthotopic immunocompetent mouse model. EpCAM+ CSCs were significantly enriched within heterogeneous Hepa1-6 CSC spheroids. Consequently, …

Establishing A Clinically Relevant Mouse Model Of Human Aml To Test Novel Transmethylation Inhibitors., Aditya Barve
Electronic Theses and Dissertations
Acute myeloid leukemia (AML) is a highly heterogeneous clonal disorder characterized by an accumulation of malignant immature myeloid progenitors in the bone marrow (BM) that hinder normal hematopoiesis. Patient AML exhibits a dramatic heterogeneity in terms of cytogenetics, disease morphology, and associated prognoses and/or chemotherapeutic sensitivity. Thus it becomes clearly evident that the investigation of novel therapeutics for AML will require model systems that are capable of recapitulating this stark heterogeneity in a patient specific manner. Furthermore, it is now understood that the surrounding bone marrow (BM) microenvironment and supporting cells play a critical role in leukemic progression as well …
The Influence Of Mir-99a On Mtor Signaling Regulation In Colorectal Cancer Cell Lines., Jonathan Rice
The Influence Of Mir-99a On Mtor Signaling Regulation In Colorectal Cancer Cell Lines., Jonathan Rice
Electronic Theses and Dissertations
Colorectal cancer (CRC) is the third most common cancer worldwide and the fourth most common cause of death. These are staggering statistics for a disease that can essentially be cured if caught early and the pathology is favorable to therapeutic intervention. There is currently a drastic decrease in five year survival as the cancer stage increases from locally confined disease to metastatic disease. These statistics suggest that although some strides have been made with colon cancer screening and early intervention, there is still much room for improvement in both screening and treatment of CRC. One of the pathways that have …

Microrna-186 And Metastatic Prostate Cancer., Dominique Zilpha Jones
Electronic Theses and Dissertations
MicroRNA (miR) dysregulation alters cancer-associated gene expression, which contributes to cancer pathogenesis. For example, miR-186 over expression lead to enhanced proliferation and migration in pancreatic cancer cell models. However, the role of miR-186 in prostate cancer (PCa) remains controversial. Previously, miR-186-5p was up-regulated in PCa patient serum (stage III/IV) compared to controls. Furthermore, miR-186-5p was up-regulated in metastatic PCa (PC-3, MDA PCa 2b, LNCaP) relative to normal prostate epithelial cells (RWPE1). We hypothesized miR-186 inhibition will reduce aggressive PCa using metastatic cell models. To test this, we evaluated whether miR-186-5p inhibition would reduce aggressive PCa behavior and overexpression induce malignant …
