Clopidogrel is an antiplatelet agent currently used for preventing stent thrombosis. Despite certain clinical benefits of clopidogrel in patients undergoing percutaneous coronary intervention (PCI), adequate antiplatelet effect has not been obtained in some patients. The present study was designed to investigate the potential association of ABCB1 (ATP-Binding Cassette, Subfamily B, member1) gen...

BACKGROUND The ATP-binding cassette sub-family B member 1 (ABCB1) gene, which encodes the p-glycoprotein at the blood-brain barrier, is investigated for patients' susceptibility to major depressive disorder (MDD) and their therapeutic response to antidepressants. However, there is an inconsistency between the studies of different ethnic groups. The current study aimed to determine the potential...

The critical role of ATP-binding cassette B1 (ABCB1) in the function of the blood-brain barrier led us to conducted this prospective study in order to investigate the clinical outcome of patients suffering from severe traumatic brain injury. A total of 182 patients with traumatic brain injury were included in our study. Genotyping of ABCB1 C3435T and G2677T/A was conducted using polymerase chai...

Expression of the adenosine triphosphate-binding cassette B1 (ABCB1) transporter and P-glycoprotein are associated with resistance to anticancer drugs. The purpose of this study was to investigate the role of single nucleotide polymorphism in the ABCB1 and CYP3A genes in breast cancer patients who were treated with neoadjuvant chemotherapy. Stage II/III breast cancer patients were treated with ...

OBJECTIVE Many studies have focused on the association between the ABCB1 3435C>T polymorphism and colorectal cancer (CRC) risk. However, the results were conflicting. The aim of this meta-analysis is to evaluate the precise association between this polymorphism and CRC risk. METHODS We formally reviewed the literature at Pubmed, EMBASE and the Cochrane Library with the key words as follows: A...

BACKGROUNDS The etiology of congenital heart defect (CHD) is commonly believed to involve the interaction of multiple environmental and genetic factors. This study aimed to explore the joint effects of the ABCB1 gene C3435T polymorphism and maternal periconceptional toxicants exposure on the CHD risk in a Han Chinese population. METHODS An age and gender matched case-control study with standa...

Digoxin, a drug of narrow therapeutic index, is a substrate for common transmembrane transporter, P-glycoprotein, encoded by ABCB1 ( MDR1 ) gene. It has been suggested that ABCB1 polymorphism, as well as co-administration of P-glycoprotein inhibitors, may influence digoxin bioavailability. The aim of the present study was to evaluate the effects of ABCB1 gene polymorphism and P-gp inhibitor co-...

We conducted a case-control study to investigate the role of ABCB1 C3435T (rs1045642) and C1236T (rs1128503) gene polymorphisms in the susceptibility to acute myeloid leukemia. The polymerase chain reaction (PCR) coupled with restriction fragment length polymorphism (RFLP) method was carried out to genotyping ABCB1 C3435T and C1236T gene polymorphism. Statistical analysis was conducted using th...

OBJECTIVE Multi-drug resistance gene 1 (ABCB1) is closely related to bowel diseases. Therefore, our study was aimed to evaluate the correlation between ABCB1 polymorphisms (C1236T and C3435T) and ulcerative colitis (UC) susceptibility. METHODS A total of 61 UC patients and 64 healthy people participated in the study. Genotyping was conducted with the method of polymerase chain reaction-restri...
