Abstract:The overexpression of breast cancer resistance protein (BCRP) is associated with multidrug resistance (MDR) in specific cancers. BCRP is an ATP‐binding cassette (ABC) transporter that is also functionally important in the blood brain barrier.

BCRP can also be problematic in its ability to inhibit the delivery of drugs to the brain. There are curre… Show more
