My laboratory is interested in the molecular mechanisms of cellular injuries, with the goals of preventing and suppressing neural injury during neurodegenerations as well as inducing cancer cell damages in cancer research. Currently, our projects are focused on small G-proteins of Rho family GTPase regulation. One project investigates the deregulation of Rho family small GTPases in Alzheimer’s disease while another project explores regulation of Rho GTPases signaling in the anti-cancer drug induced neurodegeneration and regeneration. An additional project employs the prostate cancer xenograft and its derived cell lines to investigate signaling through protein-protein interactions in the Rho GTPase pathway in order to understand the mechanisms of cancer progression.
