Distinct Response of Circulating microRNAs to the Treatment of Pancreatic Cancer
(Georgetown University, 2014)
An early detection and monitoring of pancreatic adenocarcinoma has been very challenging, which makes it one of the deadliest cancers today. This has stimulated research to explore new therapeutic strategies and new ways ...
The Molecular Determinants of Tumor Cell Sensitivity and Resistance to Antibody-Dependent Cellular Cytotoxicity (ADCC)
(Georgetown University, 2013)
Monoclonal antibodies represent the vanguard of targeted therapy due to their specificity and versatility. Aside from disrupting tumor cell survival and proliferation through cell surface receptor interactions, antibodies ...
THE MECHANISMS OF REVERSAL OF REFRACTORY DYSPLASIA IN THE SALIVARY GLAND: TESTING THE ROLE OF P53, RXR AND PPARGAMMA AGONISTS, AND PD0332991
(Georgetown University, 2012)
Loss of normal growth control is a hallmark of cancer progression. Therefore, understanding the early mechanisms of normal growth regulation and the changes that occur during preneoplasia may provide insights of both ...
Drivers of cancer cell invasion and metastasis
(Georgetown University, 2012)
Metastatic spread of cancer cells from their primary site requires invasion into the vasculature, extravasation at the distant organ site and colonization of the distant organ. Here we studied mechanisms of attachment and ...
CIRCUMVENTING ANTIGEN LOSS TO POTENTIATE CANCER IMMUNOTHERAPY
(Georgetown University, 2015)
Cancer cells become resistant to monoclonal antibody (mAb) therapy when they lose the cell surface antigens that mAbs target. To circumvent immune escape and maximize the efficacy of mAb therapy, new approaches to mitigate ...
Regulation of MicroRNAs Targeting the Angiogenic Switch Molecule Fibroblast Growth Factor Binding Protein 1 by Retinoic Acid Receptor Activation
(Georgetown University, 2014)
This dissertation examines the role of retinoic acid receptor activation in the post-transcriptional regulation of a fibroblast growth factor binding protein. Previous work showed that all-trans retinoic acid (ATRA) reduces ...
Molecular Features of Human Bone Marrow Stem Cells
(Georgetown University, 2012)
Understanding the quality and quantity of resident bone marrow cells as well as circulating bone marrow derived cells (BMDC) are key to unlocking the complexity of their contribution to physiological hemostasis or pathological ...
Novel Base Excision Repair and Hypoxanthine in Live Human Cells
(Georgetown University, 2018)
Elucidating the mechanism of DNA damage and mutation is key to understating cancer genesis. In the first section of this thesis we examined base excision repair enzymes (BER) responsible for mitigating damage to DNA. BER ...
Expression Levels of the Nuclear Coactivator AIB1 in Drug Resistance and Tumor Progression of Triple Negative Breast Cancer
(Georgetown University, 2019)
Breast cancer is the most diagnosed cancer and the most frequent cause of cancer mortality in women worldwide. Immunoreactive assays as well as gene expression profiling of breast cancer have shown a high degree of ...
T Cell Based Immunotherapy Targeting Fibroblast Growth Factor Receptor 4 as a Therapeutic against Rhabdomyosarcoma
(Georgetown University, 2019)
Rhabdomyosarcoma (RMS), the most common soft tissue sarcoma of childhood, has a low mutational burden with few actionable somatic targets. Fibroblast growth factor receptor 4 (FGFR4) is a candidate therapeutic target in ...
