Multidrug Resistance in Acute Myeloid Leukemia: Potential New Therapeutics
ثبت نشده
چکیده
In acute myeloid leukemias (AMLs), multidrug resistance (MDR) is frequently, but not always, caused by the MDR1 gene product, a 170to 180kDa glycoprotein known as P-glycoprotein (Pgp) or human MDR1 protein (1). It is characterized by broad resistance to several structurally, chemically, and pharmacologically distinct chemotherapeutic compounds. Many theories explain how Pgp affects MDR, including the ‘‘drug pump’’ model, in which Pgp hydrolyzes adenosine triphosphate to actively pump drugs out of the cell (2,3). As many MDR cells have been found to have

متن کاملTargeting the multidrug resistance-1 transporter in AML: molecular regulation and therapeutic strategies.
The multidrug resistance-1 (MDR1) gene product, P-glycoprotein (P-gp), and the multidrug resistance-related proteins (MRPs) are members of the adenosine triphosphate (ATP)-binding cassette (ABC) transporter gene superfamily that regulates the trafficking of drugs, peptides, ions, and xenobiotics across cell membrane barriers. Three-dimensional modeling of human MDR1/P-gp indicates that these gl...
متن کاملThe role of ATP-binding cassette transporter A2 in childhood acute lymphoblastic leukemia multidrug resistance
Acute lymphoblastic leukemia (ALL) is one of the most prevalent hematologic malignancies in children. Although the cure rate of ALL has improved over the past decades, the most important reason for ALL treatment failure is multidrug resistance (MDR) phenomenon. The current study aims to explain the mechanisms involved in multidrug resistance of childhood ALL, and introduces ATP-binding cassette...
