White blood cells from a total of 19 patients diagnosed as having acute lymphoblastic (ALL) or acute myeloid (AML) leukaemia were analysed (36 samples) for amplification and expression of the mdr1 and mdr3 genes. Nine of the patients had samples analysed at presentation and at subsequent stages of the disease (24 samples, including 4 at second relapse). Patients received standard MRC UK Trial remission-induction treatment protocols appropriate to disease and age. No amplification of either the mdr1 or mdr3 gene was found in any of the samples, and neither were mdr3 transcripts detected by dot-blot analysis using gene-specific probes. Transcripts of the mdr1 gene were found in only 2 ALL samples (of 10). However, mdr1 transcripts were detected in all AML patients and there was a significant increase in the transcript levels in these patients who went on to first and second relapse, compared with levels measured at presentation (P < 0.001). The results support the hypothesis that P-glycoprotein-mediated drug resistance may be a significant factor in tumour cell resistance to chemotherapy at relapse following initial induction-remission therapy for acute myeloid leukemia.
