Imatinib uptake was significantly enhanced in OATP1A2-transfected human embryonic kidney (HEK)293 cells (P=0.002). Naringin, an OATP1A2 inhibitor, decreased the transport of imatinib in OATP1A2-transfected HEK293, the human intestinal cell line Caco-2, and the CML cell line K562 cells. Linkage disequilibrium was found between the SLCO1A2 -1105G>A and -1032G>A genotypes in 34 CML patients and 100 healthy subjects. Imatinib clearance of CML patients was influenced by the SLCO1A2 -1105G>A/-1032G>A genotype (P=0.075) and the SLCO1A2 -361GG genotype (P=0.005). These findings suggest that imatinib is transported into cells by OATP1A2, and that SLCO1A2 polymorphisms significantly affect imatinib pharmacokinetics., http://www.nature.com/clpt/journal/v90/n1/full/clpt2011102a.html}, pages = {157--163}, title = {Pharmacokinetic impact of SLCO1A2 polymorphisms on imatinib disposition in patients with chronic myeloid leukemia}, volume = {90}, year = {2011}, yomi = {ハマダ, アキノブ} }
