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...

Data on genetic polymorphisms associated with response to anti-HIV drugs has accumulated over the years. Information on how polymorphisms influence drug metabolism and transport to target sites is important in guiding dosage or selection of appropriate alternative therapies. This study determined the frequency of MDR1 C3435T and CYP2B6 G516T polymorphisms associated with the transport and metab...

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...

BACKGROUND The prodrug clopidogrel requires intestinal absorption by the efflux pump P-glycoprotein MDR1 (multidrug resistant-1), encoded by the ABCB1 gene. Prior studies suggested that a common and functional genetic variant (C3435T, rs1045642) within ABCB1 influences clopidogrel treatment efficacy; however, existing data are highly inconsistent, because other studies failed to replicate this ...

INTRODUCTION Considering the high prevalence of liver tumors and the impact on patient survival, a greater understanding of the biological behavior of those tumors if of great importance. The multidrug resistance gene (MDR1) may present as single nucleotide polymorphism (SNP) which can affect the expression and activity of P-glycoprotein (Pgp), and high expression of Pgp has been associated wit...

BACKGROUND Despite the high prevalence of depression, the mechanism of the origin of this disease as well as the causes of resistance to therapy in some patients are still not fully understood. Increasingly, the possible role of genetic factors is considered. One of them is polymorphisms in the ABCB1 (MDR1) gene which encodes P-glycoprotein, responsible for the transport of xenobiotics, includi...

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...
