139 For example, the SNP G3140C in exon 23 which causes a Ser substitution of Cys1047 in CL6 appears to occur at a much higher frequency (4.5%) in African-American populations than in Caucasian populations where it has not been detected in any of the individuals screened thus far. To date, none of the reported MRP1 polymorphisms have been associated with any medical condition or unusual drug responses, although it should be borne in mind that the number of individuals screened is still relatively low and clinical information is scant.

69 We also detected three known nonsynonymous variations, 218CÀT (Thr73Ile), 2168GÀA (Arg723Gln), and 3173GÀA (Arg1058Gln) at frequencies of 0.007, 0.065 and 0.003, respectively. These frequencies were similar to those found in the earlier reports for Japanese11) and Chinese.21) One of the variations, Arg723Gln, leads to reduced transport activities for LTC4, estradiol 17b-glucuronide and methotrexate.12) We did not detect three previously reported variations: 2012GÀT (Gly671Val; found with approximately 0.03 frequency in Caucasians), 3140GÀC (Cys1047Ser; 0.05 in African-Americans), and 4535CÀT (Ser1512Leu; 0.03 in Caucasians).8,9,12) These SNPs might be ethnic- speciˆc.

153 To determine whether the five nsSNPs, R633Q, G671V, R723Q, A989T, and C1047S, affected the ability of MRP1 to mediate efflux of calcein, HEK293 cells stably expressing wild-type and mutant MRP1 as well as untransfected HEK cells were incubated with several concentrations of the cell permeable acetoxymethyl ester of calcein (calcein-AM) at 37&#b0;C; 3 hours later, the intracellular hydrolyzed calcein that had not been effluxed by MRP1 was measured.

157 Thus, unlike the chemosensitivity assay, which showed that the drug-resistance patterns of A989T and C1047S were different from wild-type MRP1 (Table 2), the calcein efflux assay did not detect any differences (Fig. 3).

211 Membrane vesicles prepared from HEK293 cells expressing wild-type [WT (d)], A989T (s), and C1047S (m) mutant MRP1 were preincubated with a range of concentrations of (A) BAYu9773, (B) LY171883, and (C) LY465308 (+ GSH), and then ATP-dependent [3 H]E217bG uptake was measured after 5 minutes in the continued presence of the modulators as described in Materials and Methods.

246 (A) ATP-dependent uptake of [3 H]GSH (100 mM/120 nCi) in the presence of apigenin (30 mM) was measured in membrane vesicles prepared from HEK293 cells expressing wild-type, A989T and C1047S MRP1 for 20 minutes at 37&#b0;C.

258 The third and final category consists of A989T and C1047S which, despite the fact that most predictive methods indicated they were unlikely to affect MRP1 activity, exhibited altered phenotypes that distinguished them not only from wild-type MRP1 but to some degree from each other.

259 Thus, HEK cells expressing A989T or C1047S differed in their drug-resistance profiles and their sensitivity to LY465803- mediated inhibition of calcein efflux, as well as their cellular GSH levels as detected in cell-based assays.

260 The C1047S affected both vincristine and etoposide resistance while the A989T mutation affected only vincristine resistance.

262 Inhibition of calcein efflux by the GSH-dependent LY465803 was also reduced in A989T cells but not C1047S cells.

263 In contrast, membrane-based vesicular transport assays indicated that A989T and C1047S did not affect the ability of LY465803 to inhibit MRP1-mediated E217bG uptake.
