1 Moreover, 15d-PGJ(2)-induced GCLC expression was attenuated by the MK571 and also by siRNA knockdown of MRP1, suggesting that MRP1 contributes to 15d-PGJ(2)-mediated up-regulation of GCLC by pumping out the 15d-PGJ(2)-GSH conjugate.

3 It is speculated that 15d-PGJ(2), once effluxed through MRP, liberates from the GSH conjugate, and the free 15d-PGJ(2) re-enters the cell and forms the GSH conjugate again. Glutathione ATP binding cassette subfamily C member 1 Homo sapiens

5 In conclusion, MRP1 mediates Nrf2-dependent up-regulation of GCLC in 15d-PGJ(2)-treated MCF-7 cells, possibly via a putative recycling loop of 15d-PGJ(2)-GSH conjugation. Glutathione ATP binding cassette subfamily C member 1 Homo sapiens
