摘要: Knowledge concerning transport of maternally administered drugs across the placental barrier is essential for determining potential toxicity to fetus and value drug therapy during pregnancy. An important determinant fetal exposure expression efflux transporters in placenta. Among human tissues, ATP-binding cassette transporter BCRP (gene symbol ABCG2) most abundantly expressed apical membrane syncytiotrophoblasts. Although precise physiological role placenta still unclear, existing data strongly suggest that plays an protecting against drugs, xenobiotics, metabolites by expelling them barrier. In this review, we summarize current knowledge with respect expression, function, polymorphisms BCRP, as well transcriptional posttranscriptional regulation Finally, clinical significance pregnant women discussed.
