The MDR1 multidrug transporter regulates the traffic of drugs, peptides and xenobiotics into the body as well as sensitive tissues like the brain, germ cells and the developing fetus. Hence, it may influence an individual's response to drugs as well as his/her susceptibility to complex diseases in which environmental factors, especially xenobiotics, play a(More)
Searching for genomic evidence of positive selection has been hailed as an attractive strategy for identifying functional polymorphisms. Here, we demonstrate the feasibility of identifying functional polymorphism at the MRP1 gene locus using this strategy. The 190 kDa MRP1 protein is an efflux pump that regulates the accumulation of xenobiotics and drugs in(More)
The major histocompatibility complex (MHC) containing the classical human leukocyte antigen (HLA) Class I and Class II genes is among the most polymorphic and diverse regions in the human genome. Despite the clinical importance of identifying the HLA types, very few databases jointly characterize densely genotyped single nucleotide polymorphisms (SNPs) and(More)
BACKGROUND The MRP1 gene encodes the 190 kDa multidrug resistance-associated protein 1 (MRP1/ABCC1) and effluxes diverse drugs and xenobiotics. Sequence variations within this gene might account for differences in drug response in different individuals. To facilitate association studies of this gene with diseases and/or drug response, exons and flanking(More)
In order to provide gene expression profiles of different cell types, the primary step is to isolate the specific cells of interest via laser capture microdissection (LCM), followed by extraction of good quality total RNA sufficient for quantitative real-time polymerase chain reaction (qPCR) analysis. This LCM-qPCR strategy has allowed numerous gene(More)
