Brief Summary:
Transporters in kidney are critical in detoxification and elimination of xenobiotics from systemic circulation and thus are major determinants of drug response and sensitivity Transporters in the renal epithelium control the exposure of renal cells to nephrotoxic drugs and environmental toxins and thus determine xenobiotic-induced nephrotoxicity Organic anion transporters OATs and organic cation transporters OCTs are two major classes of secretory transporters in the mammalian kidney Among the uptake transporters OAT1 OAT3 or OCT2 appear to be particularly important in the renal basolateral membrane to transport a large variety of endogenous and therapeutic compounds
Recently rapid advances in single nucleotide polymorphisms SNPs mapping can now be applied to characterize the individual patients who suffer adverse effects to a drug or those for whom a drug shows efficacy The aim of this study was to identify and functionally characterize OCT2 variants as a first step towards understanding whether genetic variation in OCT2 may contribute to interindividual differences in renal elimination of vancomycin Taiwanese patients will be screened and 12 coding region variants of OCT2 will be identified The non-synonymous variants of OAT1 OAT3 or OCT2 will then be constructed and characterized using in vitro human renal cell models It is to establish whether genetic variants in OAT1 OAT3 or OCT2 are likely significant contributors to intersubject variability in drug response In addition approaches toward prevention of some drug-induced nephrotoxicity are discussed based on molecular mechanisms of renal accumulation of these drugs Perhaps the researchers understanding of OAT1 OAT3 or OCT2 in pharmacogenomics may contribute to the goal of individualized drug therapy Development of new strategies based on the understanding of their cellular handing may achieve safer and more effective therapy for personalized medicines

Detailed Description:
Beta-lactam antibiotics aminoglycosides amphotericin B cyclosporine nonsteroidal anti-inflammatory drugs antineoplastic or antivirus drugs that are used extensively in clinical settings bear the risk of nephrotoxicity This side effect is dose-dependent and has been attributed mainly to the accumulation of drugs in the renal proximal tubule When assessing nephrotoxicity both the dosage and the tubular secretion system which allows transport of drug from blood to urine via the tubular cells are important factors This study was designed to investigate how renal transporters work in the renal secretion of specific drugs
