Drugs and chemicals are often too large to enter and exit cells unassisted. Transporter proteins can be used as gates that regulate which chemicals leave cells. In fact, the ATP-binding cassette transporters (ABC) are members of a superfamily of transporters found in the plasma membrane. ABC transporters function as efflux pumps that remove chemicals from the cell. Our laboratory studies members of three families of efflux transporters: ABCB1 (Multidrug resistance protein 1, MDR1, P-glycoprotein), ABCC1-6 (Multidrug resistance-associated proteins, MRP), and ABCG2 (Breast cancer resistance protein, BCRP). These transporters are important in removing chemicals from the liver and kidneys and can protect against target organ toxicity. Similarly, these efflux pumps are expressed in the placenta and participate in maternal-fetal xenobiotic disposition, thereby protecting the developing fetus from toxicant exposure.
Dr. Aleksunes’ laboratory investigates how drug transporters in the liver, kidneys, brain, and placenta protect against the accumulation and toxicity of pharmaceuticals and environmental chemicals. Her studies aim to 1) characterize substrates and inhibitors for efflux transporters, 2) determine how genetic variants influence transporter function, and 3) understand the regulatory mechanisms that control expression of transporters. Dr. Aleksunes’ laboratory utilizes molecular biology, cell biology, in vivo transgenic animal, explant human tissue, biomarkers of toxicity, and pharmacokinetic approaches to study the interplay of drug transport and toxicology.
