1 We assessed the bone marrow uptake of (99m)Tc-MIBI and its correlation with messenger RNA (mRNA) levels of MDR1, multidrug-resistance associated protein-1 (MRP1) and lung resistance protein (LRP) in acute leukaemia. Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
2 RESULTS: There was an inverse relationship between (99m)Tc-MIBI uptake of bone marrow and both mRNA levels of MDR1 and MRP1 (P=0.000, r= -0.733 and P=0.001, r= -0.610, respectively). Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
3 CONCLUSION: Increased expression of MDR1 and MRP1 correlates with a low accumulation of (99m)Tc-MIBI in bone marrow areas in patients with acute leukaemia. Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
4 (99m)Tc-MIBI bone marrow scintigraphy can identify the MDR1 and MRP1 phenotype, but not LRP, in patients with acute leukaemia. Technetium Tc 99m Sestamibi ATP binding cassette subfamily B member 1 Homo sapiens
