1 Expression of GSTP1-1 was associated with a fourfold to tenfold protection from 4NQO-induced cytotoxicity. 4-Nitroquinoline-1-oxide glutathione S-transferase pi 1 Homo sapiens
2 Moreover, MRP2 efflux activity also augmented GSTP1-1-mediated protection from 4NQO-induced nucleic-acid adduct formation. 4-Nitroquinoline-1-oxide glutathione S-transferase pi 1 Homo sapiens
3 We conclude that MRP2-mediated efflux of the glutathione conjugate of 4NQO and/or another toxic derivative of 4NQO is required to support GSTP1-1-associated protection from 4NQO toxicities in HepG2 cells. 4-Nitroquinoline-1-oxide glutathione S-transferase pi 1 Homo sapiens
4 We conclude that MRP2-mediated efflux of the glutathione conjugate of 4NQO and/or another toxic derivative of 4NQO is required to support GSTP1-1-associated protection from 4NQO toxicities in HepG2 cells. 4-Nitroquinoline-1-oxide glutathione S-transferase pi 1 Homo sapiens
