PG - 337-9 AB - A transgenic cell line stably expressing the human organic anion transporting polypeptide (OATP1B1) was established. Human Embryonic Kidney 293 (HEK293) cell line stably expressing OATP1B1*1a sequence was amplified through PCR with the extracted total RNA as templates from human liver, then subcloned into the plasmid pMD19-T and verified by sequencing. OATP1B1*1b/OATP1B1*15 mutant sequences were obtained by site-directed mutation PCR with pMD19-T/ OATP1B1*1a as templates. The plasmids pcDNA3.1(+)/OATP1B1*1a, *1b and *15 were constructed and transfected into HEK293 cell line using Lipofectamine 2000 transfection reagent. Several stable transfected clones were obtained after selection with G418. Using rosuvastatin as a probe substrate of OATP1B1, the intracellular rosuvastatin accumulation in HEK293 and HEK-OATP1B1*1a, *1b and *15 monoclone cells were validated by a ultra-performance liquid chromatography-tandem mass spectrometry. OATP1B1 mRNA and protein expression were detected by RT-PCR and Western blot, respectively. The results from RT-PCR, rosuvastatin uptake and Western blot assay indicated that human OATP1B1 was highly expressed in transfected cells compared with controls. The HEK-293 cell lines stably expressing human OATP1B1-wild and variant (HEK-OATP1B1, *1b and *15) are potential models to study drug transport in vitro.
