ATP-binding cassette transporter B1 (ABCB1; P-glycoprotein; multidrug resistance protein 1) is an adenosine triphosphate (ATP)-dependent efflux transporter located in the plasma membrane of many different cell types. Numerous structurally unrelated compounds, including drugs and environmental toxins, have been identified as substrates. ABCB1 limits the absorption of xenobiotics from the gut lumen, protects sensitive tissues (e.g. the brain, fetus and testes) from xenobiotics and is involved in… 

Effect of ABCB1 genetic polymorphisms on the transport of rivaroxaban in HEK293 recombinant cell lines

It is suggested that the ABCB1 coding SNPs investigated in the present study are unlikely to contribute to the inter-individual variability in rivaroxaban plasma concentrations.

Combinations of common SNPs of the transporter gene ABCB1 influence apparent bioavailability, but not renal elimination of oral digoxin

The population pharmacokinetic model supports the use of oral digoxin as a phenotyping substrate of intestinal P-gp, but not to assess renal P- gp activity, and the relationship between SNP combinations and digoxin pharmacokinetics was explored.

Effect of four ABCB1 genetic polymorphisms on the accumulation of darunavir in HEK293 recombinant cell lines

It is demonstrated that while ABCB 1 expression limits intracellular accumulation of darunavir, there is no significant difference in efflux activity between cells expressing wild-type ABCB1 and those that express any of the studied variants.

Polymorphisms of ABCB1, CYP3A4 and CYP3A5 Genes in Ovarian Cancer and Treatment Response in Poles.

Findings from this study may contribute to a better prediction of therapy outcome in Polish women and their response to treatment.

The Food and Drug Administration, the European Medicines Agency, and the Japanese Pharmaceuticals and Medical Devices Agency have identified seven transporters which need to be tested for investigational drug disposition, including two multidrug resistance protein 1 (MDR1) and the breast cancer resistance protein (BCRP).

Influence of Single Nucleotide Polymorphisms on Rifampin Pharmacokinetics in Tuberculosis Patients

This narrative review aims to identify literature that has explored the influence of single nucleotide polymorphisms of genes encoding drug transporters and their transcriptional regulators, metabolizing enzymes, and VDR and its pathway regulators on plasma RF concentrations in TB patients on antitubercular therapy.

Current knowledge of the functional significance genetic variants of ABC membrane transporters does not allow selection of a particular SNP to predict an individual's pharmacokinetics.

Clinical aspects of the MDR1 (ABCB1) gene polymorphism.

The impact of MDR1 polymorphisms on pharmacokinetics and pharmacodynamics of Pgp substrates is moderate, and clinical studies on the effects of the C3435T polymorphism and drug treatment with cardiac glycosides, the immunosuppressants cyclosporine and tacrolimus, HIV protease inhibitors, and tricyclic antidepressants are discussed.

Modulation of multidrug resistance P-glycoprotein 1 (ABCB1) expression in human heart by hereditary polymorphisms.

The present study based on auricular samples suggests that genetic factors play a rather limited role in modulating P- gp expression in human heart, and the substantial interindividual variability in cardiac P-gp expression is likely related to environmental or disease related factors.

Genetic polymorphisms of the human MDR1 drug transporter.

P-glycoprotein can be inhibited or induced by xenobiotics, thereby contributing to variable drug disposition and drug interactions, and potential implications of MDR1 polymorphisms for drug disposition, drug effects, and disease risk are discussed.

Polymorphisms of the drug transporters ABCB1, ABCG2, ABCC2 and ABCC3 and their impact on drug bioavailability and clinical relevance

Variation of bioavailability and drug response may be attributed only by a small amount to polymorphisms in transporter genes, whereas transcriptional regulation or post-transcriptional modification seems to be more critical.

Substrate-Dependent Effects of Human ABCB1 Coding Polymorphisms

Functional data demonstrate that nonsynonymous polymorphisms in ABCB1 may selectively alter P-gp transport and drug-drug interactions in a substrate- and inhibitor-dependent manner.

Role of pharmacogenetics of ATP-binding cassette transporters in the pharmacokinetics of drugs.

MDR1 pharmacogenetics: frequency of the C3435T mutation in exon 26 is significantly influenced by ethnicity.

The high frequency of the C allele in the African group implies overexpression of PGP and may have important therapeutic and prognostic implications for use of P GP dependent drugs in individuals of African origin.
