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 ...
Introduction: Infertility is defined as the inability of the couples to achieve pregnancy after 12 months of unprotected intercourse. P-glycoprotein (P-gp) also known as multidrug resistance protein 1 (MDR1) is an important protein of the cell membrane that pumps many foreign substances out of cells and has a protective role in sensitive tissues such as testis. MDR1 gene is located on q21.1 of ...
BACKGROUND Inflammatory bowel disease (IBD) is a chronic disease of unknown etiology in which genetic factors contribute to development of disease. Single nucleotide polymorphisms (SNPs) in multidrug resistance 1 (MDR1) gene encoding transporter P-glycoprotein have been associated with IBD, but their role in disease susceptibility remains unclear. Therefore, the aim of this study was to investi...
یکی از مشکلات دردرمان بیماران مبتلا به سرطان مقاومت دارویی است ،به طوری که این بیماران نسبت به داروهای مختلف که مکانیسم های اثرمتفاوتی دارند مقاوم می شوند. مقاومت دارویی پدیده پیچیده ای است که در آن ژن های متعددی که تنظیم کننده انتقال دارو، ترمیم سلولی، خنثی کردن سموم ومتابولیسم داروها می باشند نقش دارند.با این وجود در اغلب رده های سلولی و بیماران سرطانی افزایش فعالیت ژن های abc transporter می ...
BACKGROUND One third of patients with epilepsy have drug-resistant epilepsy, which is associated with an increased risk of death and debilitating psychosocial consequences. Because this form is resistant to multiple antiepileptic drugs, the mode of resistance must be nonspecific, involving drug-efflux transporters such as ATP-binding cassette sub-family B member 1 (ABCB1, also known as MDR1 and...
OBJECTIVES Conflicting data from studies on the potential role of multidrug resistance 1 gene polymorphisms in inflammatory bowel disease may result from the analysis of genetically and geographically distinct populations. Here, we investigated whether multidrug resistance 1 gene polymorphisms are associated with inflammatory bowel diseases in patients from Rio de Janeiro. METHODS We analyzed...
BACKGROUND AND OBJECTIVE The exploration for the etiology of osteonecrosis of the femoral head (ONFH) has got some promising findings, but the morbidity of ONFH is still not under control. The C3435T polymorphism of ATP-binding cassette subfamily B member 1 (ABCB1) gene has been reported to possess significant influence on ONFH onset, but relevant outcomes remain conflicting rather than conclus...
PURPOSE To investigate the association of ABCB1-C3435T transition with breast cancer risk which was followed by a meta-analysis. METHODS In a case-control study we collected blood samples from 290 women (including 150 breast cancer patients and 140 healthy controls). ABCB1-C3435T genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. ...
