In these cells, n-3 PUFAs reduce transcript levels of the BA synthesizing enzymes CYP7A1, CYP27, and CYP8B1 and of the apical BA importer NTCP, while increasing those of the BA exporters MRP2, MRP3, MRP4
, and OST[beta] and of the metabolizing SULT2A1 enzyme (Figure 6).

Genes of interest were analyzed using TaqMan Master Mix and TaqMan Gene Expression Assays (Life Technologies): Sodium-dependent glucose cotransporter 1 (Sglt1), Rn00564718_m1; Sglt2, Rn00574917_m1; Oat1, Rn00568143_m1; Oat2, Rn00585513_m1; Oat3, Rn00580082_m1; Oct1, Rn00562250_m1; Oct2, Rn00580893_m1; Mrp2, Rn00563231_m1; Mrp4

Cells were treated with 25 p.M DAS, DADS and DAIS for 24 and 48 h and gene expression levels in colo 205 cells were determined for MRP1, MRP3, MRP4
UDCA treatment of WT mice significantly increased nuclear Nrf2 expression and that of hepatic Mrp2, Mrp3, and Mrp4
For example, knocking out the gene encoding for MRP4
increases inflammatory pain threshold  and knocking out the gene encoding for MRP3 alters morphine pharmacokinetics .
and MRP5 are expressed in all cell variants, but the expression levels are differently distributed.
In particular, aspirin, indomethacin, and ibuprofen are substrates for MRP4
 and may interfere with fluorescent probe staining.
