Lapatinib 33-42 ATP binding cassette subfamily B member 1 Homo sapiens 14-18 20607587-4 2011 We examined the impact of co-incubation of chemotherapy drugs in combination with lapatinib in P-gp over-expressing drug resistant cells. Lapatinib 82-91 ATP binding cassette subfamily B member 1 Homo sapiens 95-99 20607587-5 2011 Unexpectedly, lapatinib treatment, at clinically relevant concentrations, increased levels of the P-gp drug transporter in a dose- and time-responsive manner. Lapatinib 14-23 ATP binding cassette subfamily B member 1 Homo sapiens 98-102 20607587-7 2011 Despite the lapatinib-induced alteration in P-gp expression, use of accumulation, efflux and toxicity assays demonstrated that the induced alteration in P-gp expression by lapatinib had little direct impact on drug resistance. Lapatinib 12-21 ATP binding cassette subfamily B member 1 Homo sapiens 44-48 20607587-7 2011 Despite the lapatinib-induced alteration in P-gp expression, use of accumulation, efflux and toxicity assays demonstrated that the induced alteration in P-gp expression by lapatinib had little direct impact on drug resistance. Lapatinib 172-181 ATP binding cassette subfamily B member 1 Homo sapiens 153-157
