Research Statement

My research focuses on the changes in intracellular oxidation-reduction potential as a signaling mechanism in response to select dietary phytochemicals. Many of these phytochemicals have been shown to be cancer preventive at concentrations that oxidize glutathione and cysteine. We are investigating the relationship between this alteration in redox potential and the induction of cell cycle arrest in human cancer cell lines. These studies involve flow cytometry and changes in the expression of p53, p21 and p27 protein and their role in cell cycle arrest, specifically G2/M arrest.
