The temporal relationship between ABCB1 promoter hypomethylation, ABCB1 expression and acquisition of drug resistance [PDF]
Induced expression of the Abcb1 drug transporter often occurs in tumors in response to chemotherapy. The role that epigenetic modifications within the ABCB1 promoter play in Abcb1 expression remains unclear. We selected MCF-7 cells for survival in increasing doses of chemotherapy drugs, and assessed the methylation status of 66 CpG sites within the ...

Targeted nanopore sequencing for the identification of ABCB1 promoter translocations in cancer
Background Resistance to chemotherapy is the most common cause of treatment failure in acute myeloid leukemia (AML) and the drug efflux pump ABCB1 is a critical mediator.

Not only P-glycoprotein: amplification of the ABCB1-containing chromosome region 7q21 confers multidrug resistance upon cancer cells by coordinated overexpression of an assortment of resistance-related proteins [PDF]
The development of drug resistance continues to be a dominant hindrance toward curative cancer treatment. Overexpression of a wide-spectrum of ATP-dependent efflux pumps, and in particular of ABCB1 (P-glycoprotein or MDR1) is a well-known resistance ...

Lapatinib potentiates cytotoxicity of YM155 in neuroblastoma via inhibition of the ABCB1 efflux transporter [PDF]
Adverse side effects of cancer agents are of great concern in the context of childhood tumors where they can reduce the quality of life in young patients and cause life-long adverse effects.

Effects of Polyphenols on P-Glycoprotein (ABCB1) Activity [PDF]
P-glycoprotein (Pgp, ABCB1) is a member of one of the largest families of active transporter proteins called ABC transporters. Thanks to its expression in tissues with barrier functions and its broad substrate spectrum, it is an important determinant of the absorption, metabolism and excretion of many drugs.

Association of ABCB1, 5-HT3B receptor and CYP2D6 genetic polymorphisms with ondansetron and metoclopramide antiemetic response in Indonesian cancer patients treated with highly emetogenic chemotherapy. [PDF]
Our study shows that in Indonesian cancer patients treated with highly cytostatic emetogenic, carriership of the CTG haplotype of the ABCB1 gene is related to an increased risk of delayed chemotherapy-induced nausea and ...

Carboplatin/taxane-induced gastrointestinal toxicity: a pharmacogenomics study on the SCOTROC1 trial [PDF]
Carboplatin/taxane combination is first-line therapy for ovarian cancer. However, patients can encounter treatment delays, impaired quality of life, even death because of chemotherapy-induced gastrointestinal (GI) toxicity.

Mechanism of multidrug recognition by MDR1/ABCB1 [PDF]
MDR1/ABCB1, a member of the ABC group of proteins, is clinically important because it is not only involved in multidrug resistance in cancer but also affects the pharmacokinetic properties of various drugs. The most puzzling feature of MDR1 is that it recognizes and transports such a wide variety of substrates.
