Cellular levels of acitretin with different SLCO1B1 rs4149056 alleles. Legend: (A) Uptake of acitretin was significantly higher in HEK293-SLCO1B1 cells than in HEK293-MOCK cells. (B) Uptake mediated by SLCO1B1 521 C allele was less than that in the wild-type 521 T cells. (C,D) Uptake of acitretin mediated by SLCO1B1 was inhibited by rifampicin. SLCO1B1 521 T is the wild-type allele, and 521 C is the variant.
