Cyclosporine A (CsA) is a substrate for cytochrome P450 3A and the efflux transporter P-glycoprotein (P-gp; ABCB1), both abundantly expressed in the kidney. We retrospectively investigated the role of polymorphisms in CYP3A4, CYP3A5 and ABCB1 kidney graft donors on recipient renal function and subsequent graft loss, in a long-term cohort of recipients transplanted between 1990 and 2005. DNA fro...

Dasatinib is effective in most chronic phase chronic myeloid leukemia patients both in first-line therapy and following imatinib failure. While imatinib uptake into CD34(+) cells is low compared to mononuclear cells, few data evaluate how well dasatinib targets primitive CML cells. This study compares intracellular concentration of dasatinib and Bcr-Abl kinase inhibition in CML-CD34(+) progenit...

Цель . Изучение связи полиморфных маркеров генов репарации ДНК ERCC2 (rs13181), ERCC5 (rs17655), транспортного белка ABCB1 (rs1045642, rs2032582) с клиническим ответом и степенью патоморфологической регрессии (ПР) опухоли у беременных женщин онкологическими заболеваниями после ХТ препаратами платины.

There is accumulating evidence to suggest that overexpression of efflux drug transporters at the blood-brain barrier, by reducing antiepileptic drug (AED) accumulation in the seizure foci, contributes to drug resistance in epilepsy. P-glycoprotein, encoded by the ABCB1 gene, is the most studied drug transporter. There are conflicting data as to whether the CC genotype of the ABCB1 3435C>T polym...

BACKGROUND Parkinson's disease (PD) is the second most frequent neurodegenerative disorder. Previous publications have investigated the association of NOS1 and ABCB1 polymorphisms with PD risk. However, those studies have provided some contradictory results. METHODS Literature searches were performed using PubMed, Embase, PDgene, China National Knowledge Infrastructure database, and Google Sc...

OBJECTIVE To investigate whether single nucleotide polymorphisms (SNP) of drug transporter proteins for TDF is a risk factor for TDF-related renal function decrement. METHODS This study investigated the association between 3 SNPs (ABCC2-24, 1249, and ABCB1 2677), which are shown to be associated with TDF-induced tubulopathy, and clinically important renal outcomes (>10ml/min/1.73m2 decrement ...

BACKGROUND The multidrug transporter P-glycoprotein (PGP) is expressed in the human placenta. In particular the C3435T ABCB1 polymorphism was associated with altered tissue expression of PGP in the human placenta. However, the potential functional impact of this polymorphism on the offspring is unknown so far. METHODS We analyzed the impact of the ABCB1/C3435T polymorphism on fetal growth in ...

The purpose of this study is to investigate associations between allelic variations of ABCG2 and ABCB1 with skin toxicity, diarrhea, liver injury and interstitial lung disease (ILD) in gefitinib-treated patients. A prospective clinical study of 83 Japanese patients with non-small-cell lung cancer was performed. Polymorphic loci in ABCG2 and ABCB1 were genotyped, and their effects on gefitinib t...

Multixenobiotic resistance (MXR) is an important mechanism of cellular efflux mediated by ATP binding cassette (ABC) transporters that bind and actively remove toxic substrates from the cell. This study was the first to identify ABC transporter P-glycoprotein (P-gp/ABCB1) as a representative of the MXR phenotype in earthworm (Eisenia fetida). The identified partial cDNA sequence of ABCB1 overla...

Methylation-controlled J protein (MCJ) is a newly identified member of the DnaJ family of cochaperones. Hypermethylation-mediated transcriptional silencing of the MCJ gene has been associated with increased chemotherapeutic resistance in ovarian cancer. However, the biology and function of MCJ remain unknown. Here we show that MCJ is a type II transmembrane cochaperone localized in the Golgi ne...
