Breast Cancer Sub-Clones That Metastasize To Lung And Bone Exhibit Different Metabolic Preferences, Mollie Merrell
Breast Cancer Sub-Clones That Metastasize To Lung And Bone Exhibit Different Metabolic Preferences, Mollie Merrell
Honors Theses
Metastasis is responsible for the majority of cancer related deaths. In breast cancer the lungs and bones are the major sites for metastasis. Previous studies used the metastatic aggressive MDA-MB-231 breast cancer line to isolate sub-clones that preferentially invade the lungs (LM line) or bones (BoM line). While genes associated with the tissue specific metastasis have been identified, it is unknown if metabolic adaptations contribute to the growth of the LM and BoM lines in their respective organs. The goal of this study was to test the hypothesis that the LM and BoM lines exhibit differences in glucose and glutamine …
Glucose Metabolism Of Breast Cancer Sub-Clones That Preferentially Metastasize To The Lungs And Bone, Anna G. Skubiz
Glucose Metabolism Of Breast Cancer Sub-Clones That Preferentially Metastasize To The Lungs And Bone, Anna G. Skubiz
Honors Theses
Malignant breast cancers exhibit preferential metastasis to bone and lung (1). While changes in gene expression in lung-specific (LM) and bone-specific metastasis (BoM) lines derived from the MDA-MB-231 breast cancer line have been identified, few metabolic genes are differentially expressed; thus it is unknown if tissue-specific metabolic reprogramming occurs. Two hallmarks of cancer cells are an altered metabolic phenotype characterized by enhanced conversion of glucose to lactate in spite of adequate oxygen availability for complete mitochondrial oxidation of this substrate (referred to as aerobic glycolysis or the Warburg effect) and a greater dependence on glutamine. These changes in primary tumor …
Cell Proliferation And Viability Inhibition By Resveratrol On Breast Cancer Cell Lines, Kyle Ford Gordon Jr
Cell Proliferation And Viability Inhibition By Resveratrol On Breast Cancer Cell Lines, Kyle Ford Gordon Jr
Honors Theses
Antioxidants are well-known for their various health benefits. They are able to protect cells from being damaged by free radicals that are produced by vital biochemical processes. It has long been known that antioxidants are important in our everyday health, but their potential as disease preventers and potential therapeutic agents is a relatively new field of study. Resveratrol, a natural polyphenol and well-known antioxidant, is found in plants, fruits, and products derived from them, like red wine. Resveratrol has been shown to have various properties, including antiaging, anti-aggregation of platelets, anti-inflammatory, and anticancer activities. Because of their many health benefits, …
Developing A New Water-Soluble Porphyrin As A Potential Photodynamic Cancer Therapy Agent, Catherine Shirley
Developing A New Water-Soluble Porphyrin As A Potential Photodynamic Cancer Therapy Agent, Catherine Shirley
Honors Theses
Photodynamic cancer therapy (PDT) is a type of treatment involving the use of light in conjunction with a photosensitive agent- a chemical or series of chemicals designed for activation when exposed to light. This research project investigated the synthesis and identification of the novel photosensitive agent, H2TPP-Pro-OH. To create the water-soluble porphyrin, (S)-(+)-prolinol was reacted with the tetra-carboxyl porphyrin, H2TPPC, to form the final H2TPP-Pro-OH product. This compound was then purified using syringe filtration and column chromatography, and subsequently characterized using infrared (IR), nuclear magnetic resonance (NMR), and Ultraviolet-visible (UV-vis) spectroscopies, as well as High Performance Liquid Chromatography (HPLC). Finally, …
Preparation And Cytotoxicity Of Novel Carbon Nano-Onion Materials, Cammie York
Preparation And Cytotoxicity Of Novel Carbon Nano-Onion Materials, Cammie York
Honors Theses
The applications of carbon nanomaterials (CNM), including graphene and its derivatives such as carbon nanotubes (CNTs) in nanomedicine is well established. These nanomaterials have been widely used as theranostic delivery systems with the potential to deliver bioactive agents and simultaneously detect selectively diseased tissues. A rather underexplored CNM for biomedical imaging and theranostics delivery are carbon nano-onions (CNOs). CNOs are carbon-based nanomaterials that can potentially be used in cancer therapy when they are functionalized. Recent studies on cellular fate of different CNMs, including CNOs, have demonstrated that the surface composition is critical for the in vivo application of these CNM. …
