Proteinated Subnano Particles of Elemental Selenium for the Treatment of Breast Cancer
Abstract
The purpose of this award is to test in preclinical models the hypothesis that cytotoxic conjugates of elemental selenium and proteins are safe and effective for the systemic therapy of invasive breast cancer. The grant has three specific aims, 1) to evaluate the safety and efficacy of systemically administered Se(0)- protein conjugates in athymic nude mice bearing xenografts of human breast cancer cells, 2) to assess the functional integrity of conjugate-treated normal human hematopoietic stem cells, and 3) to determine by use of the combination index method how Se(0)-protein conjugates interact with standard chemotherapeutic agents that are commonly used in the treatment of invasive breast cancer. We report here on the preparation and evaluation of high potency cytotoxic Se(0)-protein conjugates, a quantitative in vitro analysis of the interactions of Se(0)-protein conjugates with other chemotherapeutic agents, the surprise finding that certain antibiotics can interfere with the generation of cytotoxic conjugates, and a simple and rapid spectroscopic method to detect such interferences.
