Profiling Resistance To P450-Activated Food Carcinogens Using Toxicogenomic Approaches In Budding Yeast, Nicholas Stjohn
Profiling Resistance To P450-Activated Food Carcinogens Using Toxicogenomic Approaches In Budding Yeast, Nicholas Stjohn

The human response to environmental carcinogens, some of which require metabolic activation, is highly variable. Factors such as environment, lifestyle, and genetics all influence the rates of exposure to and ultimate bioactivation of these compounds. Genetic factors include mutations to cell-cycle regulation, cell proliferation, and DNA repair genes; however, epidemiological studies may lack significance due to inadequate patient numbers. We used budding yeast as a model organism to determine genetic susceptibility to food-associated carcinogens, including aflatoxin (AFB1) and heterocyclic aromatic amines (HAAs). Budding yeast does not contain P450s that activate these compounds, so expression vectors were induced that contain human …
Investigation Of Enzymatically Synthesized Glycogen As A Novel Nanodendrimer For Therapeutic Delivery, Sarah Ann Engelberth
Investigation Of Enzymatically Synthesized Glycogen As A Novel Nanodendrimer For Therapeutic Delivery, Sarah Ann Engelberth

The field of medicinal chemistry is ever expanding, designing and discovering new therapeutic strategies. Oftentimes, it is challenging for these therapeutics to undergo clinical translation due to ineffective administration or unwanted toxicity in vivo. As such, drug delivery vehicles are designed to overcome these hurdles, allowing for delivery to the site of action by improving biodistribution, protecting therapeutic cargo, and decreasing toxicity. The work presented here aims to investigate a naturally-derived carbohydrate nanodendrimer, enzymatically synthesized glycogen (ESG) for drug delivery. This nontoxic, highly-branched, glucose-based structure has interior void volumes to allow for cargo encapsulation as well as a large density …

Human breast cancer is currently the highest diagnosed form of cancer and the second leading cause of cancer-related deaths in American women. Triple negative breast cancer is of the basal subtype and displays the worst prognosis owing to its highly metastatic properties. Current treatments focused on eradicating breast tumors in lieu of or following local therapy include chemotherapy, hormonal therapy, and targeted therapy. Hormonal therapy is not an option for triple negative breast cancer as it does not contain hormone receptors and there are currently no approved biological targeted therapies. Chemotherapy has proven unsuccessful because triple negative breast cancer is …

A shortage of viable kidneys available for transplantation exists today, as the number of individuals waiting for a kidney transplant continues to grow while the number of kidneys available each year for transplantation has remained stagnant. The development of technology that will allow for transplantation of organs that currently may be considered too damaged for transplant will provide access to a large number of donors who have experienced traumatic injury deaths resulting in loss of cardiac function. These potential donors account for the majority of all traumatic injury deaths in intensive care units, however their organs have experienced a degree …
