[Associations of SLCO1B1 polymorphisms with tacrolimus concentrations in Chinese renal transplant recipients]
Abstract:
The study aims to investigate the associations of SLCO1B1 polymorphisms with tacrolimus concentrations in Chinese renal transplant recipients. Blood samples and clinical data were collected from 89 renal transplant recipients with tacrolimus treatment. CYP3A5*3 genotypes were detected by PCR-RFLP method and SLCO1B1(rs2306283, rs4149032) genotypes were detected by Agena Bioscience Mass ARRAY® system. Trough concentrations of tacrolimus on day 7 after renal transplantation were collected from clinical data. Correlations between genetic polymorphisms and tacrolimus concentrations were analyzed by SPSS. In CYP3A5 nonexpressers, the dose-adjusted concentration of tacrolimus in SLCO1B1 rs2306283 CC carriers was considerably higher than that in CT and TT carriers. The results illustrated that SLCO1B1 rs2306283 polymorphisms were associated with tacrolimus concentrations, and genotyping for this SNP may be useful for individualized medicine of tacrolimus.
