Dr. Slitt's research interests focus on how 1) expression of drug transporters affects chemical (i.e. drug and environmental chemical) disposition and toxicity, 2) nutrition and intake of dietary antioxidants affects the expression of drug transporters, 3) liver disease (i.e. diabetes, cholestasis, and ethanol cirrohsis) affects transporter expression and chemical disposition, and 4) transporter expression affects cholesterol transport and susceptibility to gallstone formation.
