For example, healthy cells have proteins known as transporters that pump out toxic agents. One such group of proteins, called the ATP-binding cassette (ABC) transporters, expels some chemotherapy drugs, including doxorubicin, and some targeted therapies, like imatinib (Gleevec®). Enlarge

How do chemotherapies work?
