The Chemopreventive Effect Of Polymethoxyflavones: Targeting The Colorectal Cancer Stem Cells, Fei Xu
The Chemopreventive Effect Of Polymethoxyflavones: Targeting The Colorectal Cancer Stem Cells, Fei Xu
Doctoral Dissertations
Among all the cancers, the death rate of colorectal cancer is one of the highest. Evidence from both murine xenograft model and human trials have shown cancer stem cells (CSCs) are responsible for the initiation, metastasis and recurrence of multiple cancers therefore targeting colorectal CSCs would be a promising chemo-preventive/ therapeutic strategy. Polymethoxyflavones including nobiletin (NBT) and 5-demethylatednobiletin (5DN) are exclusively found in citrus peels and have been shown to have anti-cancer effects. Our previous studies in the biotransformation and tissue distribution of NBT and 5DN have shown that in order to fuller evaluate the biological impact of those two …
The Investigation Of Rhodiola Crenulata Root Extract Effects On Obesity Associated Inflammation And The Antineoplastic Mechanism In Breast Cancer Cells, Lotfi M. Bassa
Doctoral Dissertations
Obesity and breast cancer are two disease models that directly affect the United States population, as more than 35% of the adult population is obese [8], and more than 200,000 new cases of breast cancer are diagnosed in the United States per year [34]. Several diseases are associated with obesity including, cardiovascular disease, insulin resistance, increased inflammation and increased cancer risk [9,10]. Therefore it essential to understand the risks associated with obesity as well as to investigate possible preventive and/or therapeutic treatment strategies. Rhodiola crenulata is a Tibetan plant that has been used in Eastern traditional medicine to relieve depression, …
Engineering Novel Detection And Treatment Strategies For Bacterial Therapy Of Cancer, Jan T. Panteli
Engineering Novel Detection And Treatment Strategies For Bacterial Therapy Of Cancer, Jan T. Panteli
Doctoral Dissertations
Finding and treating cancer is difficult due to limited sensitivity and specificity of current detection and treatment strategies. Many chemotherapeutic drugs are small molecules that are limited by diffusion, making it difficult to reach cancer sites requiring high doses that lead to systemic toxicity and off-target effects. Tomographic detection techniques, like PET, MRI and CT, are good at identifying macroscopic lesions in the body but are limited in their ability to detect microscopic lesions. Biomarker detection strategies are extremely sensitive and able to identify ng/ml concentrations of protein, but are poor at discriminating between healthy and disease state levels due …
Mimicking The Arterial Microenvironment With Peg-Pc To Investigate The Roles Of Physicochemical Stimuli In Smc Phenotype And Behavior, William G. Herrick
Mimicking The Arterial Microenvironment With Peg-Pc To Investigate The Roles Of Physicochemical Stimuli In Smc Phenotype And Behavior, William G. Herrick
Doctoral Dissertations
The goal of this dissertation was to parse the roles of physical, mechanical and chemical cues in the phenotype plasticity of smooth muscle cells (SMCs) in atherosclerosis. We first developed and characterized a novel synthetic hydrogel with desirable traits for studying mechanotransduction in vitro. This hydrogel, PEG-PC, is a co-polymer of poly(ethylene glycol) and phosphorylcholine with an incredible range of Young’s moduli (~1 kPa - 9 MPa) that enables reproduction of nearly any tissue stiffness, exceptional optical and anti-fouling properties, and support for covalent attachment of extracellular matrix (ECM) proteins. To our knowledge, this combination of mechanical range, low …
Investigation Of Zyflamend On Ampk Signaling And Potential Interactions Of Its Components, Yi Zhao
Investigation Of Zyflamend On Ampk Signaling And Potential Interactions Of Its Components, Yi Zhao
Doctoral Dissertations
The reductionist approach contributes greatly to our understanding of anticancer properties of phytonutrients, but in vitro studies demand concentrations that are 100-1000 times higher than achievable in humans, producing results with little physiologic relevance, resulting in disappointing outcomes in clinical trials. However, maintaining these bioactives in the presence of other compounds originally derived from the food/extract of origin may synergistically lower the bioactive dose so translatability becomes feasible. The first objective of this study was to determine if bioefficacy of phytonutrients can be enhanced when used in combination at doses that are ineffective when used in isolation. In this project, …
