1 Treating R3327-AT1, Pgp-positive tumor cells at pH 7.4 with daunorubicin, cisplatin or docetaxel led to marked apoptosis induction and cell death. Daunorubicin ATP-binding cassette, subfamily B (MDR/TAP), member 1B Rattus norvegicus
2 Inhibiting Pgp with verapamil reversed the acidosis-induced chemoresistance against daunorubicin and docetaxel. Daunorubicin ATP-binding cassette, subfamily B (MDR/TAP), member 1B Rattus norvegicus
3 Since daunorubicin and docetaxel (but not cisplatin) are substrates of the Pgp, these results underline the influence of the tumor acidosis on the Pgp-mediated chemoresistance which can be counteracted by inhibition of the drug transporter. Daunorubicin ATP-binding cassette, subfamily B (MDR/TAP), member 1B Rattus norvegicus
