Cytotoxic Effects Of Ruthenium Compounds On Human Cancer Cell Lines., Katie Beth Brown Dec 2008

Cytotoxic Effects Of Ruthenium Compounds On Human Cancer Cell Lines., Katie Beth Brown

Electronic Theses and Dissertations

Chemotherapy is the most common cancer treatment. Traditionally, platinum-based drugs are used in chemotherapy. More recently, researchers have focused on ruthenium based compounds as a substitute for the platinum compounds. Ruthenium-based compounds appear to be less toxic to healthy cells than traditional platinum-based compounds. In this study, 7 ruthenium-based compounds were tested on HT-29 (colon) and MCF-7 (breast) human cancer cell lines with the specific aim of determining whether or not any of the ruthenium-based compounds exhibited cytotoxic properties. In addition, levels of vascular endothelial growth factor (VEGF) production were tested in supernate from the cancer cells treated with various …

Characterization Of Murine Cardiac Cholinergic Innervation And Its Remodeling In Type 1 Diabetes., Abigail Marie Mabe

Electronic Theses and Dissertations

Murine models have become increasingly popular to study various aspects of cardiovascular diseases due to their ease of genetic manipulation. Unfortunately, there has been little effort put into describing the distribution of autonomic nerves in the mouse heart, making it difficult to compare current findings from clinical and experimental models related to cardiovascular diseases. Furthermore, determination of the requirements for the development of this system and its maintenance in adult mice remains largely unexplored. This study represents the first detailed mapping of cholinergic neuroanatomy of the mouse heart based on immunohistochemical staining using true cholinergic markers.
