Lactones 97-104 ATP binding cassette subfamily G member 2 (Junior blood group) Mus musculus 149-153 23620484-6 2013 Notably, both BCRP and MDR1 conferred resistance to AR-67 lactone. Lactones 58-65 ATP binding cassette subfamily G member 2 (Junior blood group) Mus musculus 14-18 23620484-9 2013 In conclusion, BCRP- and MDR1-mediated efflux of AR-67 lactone confers resistance to AR-67, but OATP1B3-mediated uptake of the AR-67 carboxylate does not sensitize OATP1B3-expressing tumor cells. Lactones 55-62 ATP binding cassette subfamily G member 2 (Junior blood group) Mus musculus 15-19 19567673-8 2009 Preferential active transport of topotecan lactone over topotecan carboxylate was shown in vivo by vCSF lactone-to-carboxylate area under the curve ratios for wild-type, Mdr1a/b(-/-), Bcrp1(-/-), and Mdr1a/b(-/-)Bcrp1(-/-) mice of 5.69 +/- 0.83, 3.85 +/- 0.64, 3.61 +/- 0.46, and 0.78 +/- 0.19, respectively. Lactones 43-50 ATP binding cassette subfamily G member 2 (Junior blood group) Mus musculus 184-189 19567673-8 2009 Preferential active transport of topotecan lactone over topotecan carboxylate was shown in vivo by vCSF lactone-to-carboxylate area under the curve ratios for wild-type, Mdr1a/b(-/-), Bcrp1(-/-), and Mdr1a/b(-/-)Bcrp1(-/-) mice of 5.69 +/- 0.83, 3.85 +/- 0.64, 3.61 +/- 0.46, and 0.78 +/- 0.19, respectively.
