We conducted a case-control study to investigate the role of ABCB1 C3435T and G2677T/A in the susceptibility and prognosis of colorectal cancer patients. A total of 316 patients with colorectal cancer and 316 controls were collected between January 2009 and January 2011. Genotyping of ABCB1 C3435T and G2677T/A was conducted by the methods of Polymerase chain reaction restriction fragment length...
OBJECTIVES The effect of ABCB1 C3435T SNP on the pharmacokinetics of immunosuppressive drug tacrolimus in different studies was conflicting. So a meta-analysis was employed to study the correlation of ABCB1 C3435T SNP and the pharmacokinetics of tacrolimus at different post-transplantation times. METHOD Several studies about ABCB1 C3435T polymorphism and the pharmacokinetics of tacrolimus wer...
BACKGROUND Epilepsy is refractory to medical treatment in about one-third of the patients. The exact pathological mechanism of epilepsy pharmacoresistance is still unclear, but a decreased antiepileptic drug (AED) uptake into the brain is suspected to play a role. P-glycoprotein (Pgp), a transmembrane transporter encoded by ABCB1 gene and located at the endothelial cells of the blood-brain barr...
The ABCB1/MDR1 gene product ABCB1/P-glycoprotein is implicated in the development of colorectal cancer (CRC). NFKB1 encodes transcription factors regulating expression of a number of genes including ABCB1. We have previously found association between the ABCB1 C-rs3789243-T polymorphism and CRC risk and interactions between the ABCB1 C-rs3789243-T and C3435T polymorphisms and meat intake in rel...
BACKGROUND Human P-glycoprotein encoded by the ATP-binding cassette sub-family B member 1 (ABCB1) gene is expressed in the blood-brain barrier. ABCB1 protects the brain from many drugs and toxins such as glucocorticoids through the efflux pump. Recent evidence suggests that a specific allele of the ABCB1 gene confers susceptibility to major depressive disorder (MDD) in the Japanese population. ...
The aim of the study was to analyze the effect of ABCB1 genetic polymorphisms on the efficacy of phenytoin (PHT) treatment in epilepsy patients. In total, 200 epilepsy patients who were administered PHT were divided into the responsive and pharmaco-resistance groups depending on the clinical data of PHT treatment in epilepsy patients. The serum concentration of PHT was detected by high-performa...
Objective: To determine the frequency of the C3435T; a single nucleotide polymorphism of the ABCB1 gene for the first time in Pakistani population and compare it with the data available from other populations. Study Design: A cross-sectional study. Place and Duration of Study: Sampling was carried out at Combined Military Hospital, Rawalpindi from August 2012 to May 2013 and institute of Biomed...
Epilepsy is a common disease of the nervous system; approximately 20-30% of all patients with epilepsy are reported resistant to antiepileptic drugs. ABCB1 and ABCC2 are members of ATP-binding cassette transporter (ABC) family that is involved in the excretion of antiepileptic drugs. In this case-control study, we have investigated the role of ABCB1 rs1045642 and rs2032582 and ABCC2 rs2273697 a...
BACKGROUND The results of studies on association between ABCB1 gene polymorphisms and glucocorticoid-induced avascular necrosis of the femoral head (GANFH) are controversial. This study aimed to assess the association of ABCB1 gene polymorphisms with the risk of GANFH by conducting a meta-analysis. MATERIAL AND METHODS The PubMed, Cochrane Library, and Embase databases were searched for paper...
In order to comprehensively screen genetic variants leading to differential expression of the important human ABCB1 gene in the primary drug-metabolizing organ, ABCB1 mRNA expression levels were measured in 73 normal liver tissue samples from Chinese subjects. A set of Tag SNPs. were genotyped. In addition, imputation was performed within a 500 kb region around the ABCB1 gene using the referenc...
