1 Cellular pharmacology of mitoxantrone in p-glycoprotein-positive and -negative human myeloid leukemic cell lines. Mitoxantrone ATP binding cassette subfamily B member 1 Homo sapiens
2 In order to determine the role of p-glycoprotein in the cellular pharmacology of mitoxantrone flow cytometry and confocal microscopy were used to study two human myeloid leukemia cell lines selected for resistance to mitoxantrone (HL-60MX2) and doxorubicin (HL-60DOX). Mitoxantrone ATP binding cassette subfamily B member 1 Homo sapiens
3 In contrast, 3.1- and 2.4-fold increases were found in uptake and retention of mitoxantrone in p-glycoprotein-positive cells (HL-60DOX) incubated with verapamil. Mitoxantrone ATP binding cassette subfamily B member 1 Homo sapiens
4 Our study demonstrates that the cellular pharmacology of mitoxantrone is affected by p-glycoprotein and can be reversed at least in part by verapamil. Mitoxantrone ATP binding cassette subfamily B member 1 Homo sapiens
