Arsenic is a major environmental pollutant in many parts of the world, causing neurological disease and cancer. Dr. Liu is interested in how arsenic, in the form of arsenite, can be transported into cells. Uptake is one of the most important steps for arsenic to exert its toxicity. Dr. Liu has identified two major arsenite uptake pathways including families of aquaglyceroporins and eukaryotic glucose transporters. In her new lab in Oakland University, Dr. Liu is going to use genetic methods to investigate the molecular mechanisms of arsenite transport by these membrane proteins.
